Abstract and Figures

Anaemia among women of reproductive age (WRA) increases the risk of pregnancy-related morbidity, mortality, and poor pregnancy outcomes. Globally, there is growing interest to reduce anaemia among WRA. In Ghana, anaemia among WRA declined at the national level between 2008 (59%) and 2014 (42%). There were also important declines at the sub-national level. The Eastern region (in the south) and Upper West region (in the north) provide an interesting opportunity to understand the decline. Identifying the drivers of anaemia reduction among WRA in Ghana provides important implementation science evidence for designing effective interventions. This current study examined the drivers of reduced anaemia prevalence in women of reproductive age using data from the Ghana Demographic and Health Surveys for 2008 and 2014. Anaemia was diagnosed as haemoglobin<12.0g/dl. Data were summarized using proportions and 95% confidence intervals. A weighted binary logistic-based multivariate decomposition technique was used to identify the potential drivers of anaemia across surveys for 2003, 2008 and 2014. Sensitivity analysis was carried out to test the robustness of the results of the decomposition analysis using haemoglobin concentration. The results of the decomposition analysis were presented as endowment and coefficient effects. Statistical analysis was carried out using Stata version 15. There was an improvement in access to water and sanitation, health services, family planning, and health insurance across surveys. Drivers of anaemia reduction over time at the national level included wealth index and maternal age, education, use of hormonal contraception and body mass index (BMI). In the Eastern region, the drivers of change were household wealth index, maternal age, hormonal contraceptive use and BMI. The drivers of change in the Upper West region, were household access to water, maternal education and BMI.

ABSTRACT
Anaemia among women of reproductive age (WRA) increases the risk of
pregnancy-related morbidity, mortality, and poor pregnancy outcomes. Globally,
there is growing interest to reduce anaemia among WRA. In Ghana, anaemia
among WRA declined at the national level between 2008 (59%) and 2014 (42%).
There were also important declines at the sub-national level. The Eastern region
(in the south) and Upper West region (in the north) provide an interesting
opportunity to understand the decline. Identifying the drivers of anaemia reduction
among WRA in Ghana provides important implementation science evidence for
designing effective interventions. This current study examined the drivers of
reduced anaemia prevalence in women of reproductive age using data from the
Ghana Demographic and Health Surveys for 2008 and 2014. Anaemia was
diagnosed as haemoglobin<12.0g/dl. Data were summarized using proportions
and 95% confidence intervals. A weighted binary logistic-based multivariate
decomposition technique was used to identify the potential drivers of anaemia
across surveys for 2003, 2008 and 2014. Sensitivity analysis was carried out to
test the robustness of the results of the decomposition analysis using haemoglobin
concentration. The results of the decomposition analysis were presented as
endowment and coefficient effects. Statistical analysis was carried out using Stata
version 15. There was an improvement in access to water and sanitation, health
services, family planning, and health insurance across surveys. Drivers of anaemia
reduction over time at the national level included wealth index and maternal age,
education, use of hormonal contraception and body mass index (BMI). In the
Eastern region, the drivers of change were household wealth index, maternal age,
hormonal contraceptive use and BMI. The drivers of change in the Upper West
region, were household access to water, maternal education and BMI. The findings
suggest that multi-level interventions are needed across sectors to further reduce
anaemia among WRA.

INTRODUCTION
Anaemia among women of reproductive age (WRA) is a key public health
challenge linked with adverse health, nutrition, social, and economic challenges
[1]. Anaemia increases the risk of pregnancy-related morbidity, mortality, and poor
pregnancy outcomes such as low birth weight and stunted growth in children [2,3].
There is growing global interest [4] to reduce anaemia among WRA by half
(Sustainable Development Goals indicator 2.2.3) [5].
A third (29.9%) of WRA are anaemic [6], representing more than half a billion
women worldwide. Anaemia prevalence is classified as severe and moderately
severe in many developing countries including Ghana. The anaemia prevalence is
higher in pregnant (36.5%) than in non-pregnant women (29.6%) [7]. Worldwide,
there was a slight decline in moderate (14% in 2000 to 13% in 2019) and severe
(2% in 2000 to 1% in 2019) anaemia prevalence among WRA in 2019 [8]. Key
drivers to this reduction included actions addressing both nutrition-specific (iron
supplementation and provision of micronutrient powders) and nutrition-sensitive
interventions (biofortification, distribution and use of insecticide-treated nets) [8
10].
In Ghana, anaemia among WRA at the national level declined between 2008
(59%) and 2014 (42%) [11,12]. The decline was also observed at the sub-national
levels. The Eastern region (ER) in the southern part of Ghana had a decline from
58% in 2008 to 39% in 2014, and the Upper West region (UWR) in the north from
70% in 2008 to 36% in 2014. These two regions have been exposed to large
population-based nutrition-specific and sensitive interventions [1316] whiles the
standard anaemia interventions are nationwide. This decline provides an
opportunity to understand the drivers of reduced anaemia prevalence among WRA
to inform programming at the sub-national level. Therefore, the current study
examined the drivers of reduced anaemia prevalence in WRA using data from the
Ghana Demographic and Health Surveys for 2003, 2008 and 2014.
MATERIALS AND METHODS
Dataset source
The current study used nationally-representative data from the Ghana
Demographic and Health Survey (GDHS) years 2003, 2008, and 2014. The GDHS
is a nationally representative survey of Ghana. The data comprised women of
reproductive age (15-49 years).
https://doi.org/10.18697/ajfand.116.23075
22251
Sampling design of the GDHS
A multi-stage stratified cluster sampling technique was used to select participants
for the surveys [9,10,17]. First, there was a selection of enumeration areas (EAs),
followed by stratification and proportionate sampling from each stratum using a
probability proportionate to size. Then, 20-30 households were systematically
sampled from each EA by listing the households in the selected EAs and
households were randomly selected from the list for the survey. Further details are
referenced here [9,10,17].
Eligible women were those between ages 15-49 years and were permanent
residents or visitors who stayed in the selected households the night before the
survey. Anaemia testing and anthropometric data (height and weight) were
collected from a subsample of the eligible women who consented to be interviewed
and tested [9,10,17].
The 2003 GDHS included haemoglobin concentration and anaemia data from 5278
WRA (92.7% response rate). The 2008 GDHS included haemoglobin concentration
and anaemia status of 4,758 WRA (response rate of 96.8%). The 2014 GDHS
included 4704 WRA’s anaemia and haemoglobin data (50.1% response rate). A
pooled dataset of n= 14,740 women aged 15-49 years was included in this current
analysis (Appendix 1).
Outcome measures
Anaemia status was used as the outcome measure for this study. Anaemia was
determined using haemoglobin (Hb) concentration measured using a battery-
operated portable HemoCue analyzer. Anaemia was classified using altitude-
adjusted haemoglobin (Hb) level for women not pregnant as Hb <12.0g/dl and for
pregnant women, anaemia was Hb <11.0g/dl. Anaemia status was further
classified as severe <7.0g/dl; moderate 7.0-9.9g/dl; or mild anaemia 10.0-11.9g/dl
for not pregnant and 10.0-10.9g/dl for pregnant women. Haemoglobin
concentration was used in sensitivity analysis to test the robustness of the results
of the decomposition analysis, using anaemia status.
Covariates
The selection of the covariates was informed by the UNICEF conceptual
framework [18] of factors affecting undernutrition, and findings of published studies
reporting covariates of anaemia among WRA [1925]. The data included
household- as well as individual-level variables. The household-level variables
included household size; sex of household head; socio-economic status;
urban/rural residence; region; access to improved water sources; household toilet
https://doi.org/10.18697/ajfand.116.23075
22252
facilities and the number of insecticides treated bed nets. The individual-level
variables were anaemia status, current age, religion, marital status, parity,
ethnicity, age, educational level, hormonal contraceptive use, and possession of a
valid National Health Insurance (NHI) card [9,10,17].
Statistical analysis
Data management and analyses were carried out using Stata version 15 [26]. All
statistical analyses accounted for the complex survey structure by adjusting for the
survey weighting for each survey year. For the pooled data analysis, the standard
survey weight was denormalised by dividing the survey's standard weight by the
survey sampling fraction that is the proportion of all women aged 15 to 49 years
who were interviewed during the survey year to all women at the time of the
survey). The GDHS datasets were used to determine the total number of women
aged 15 to 49 years who were interviewed during the survey year, and
OurWorldinData [27] was used to determine the total number of women aged 15 to
49 years who were living in the nation (Ghana) at the time of the survey. This is
represented by the formula:
women&sampling&weight&from&in&the&DHS ×total&females&aged&15 49&in&the&country&during&the&survey&
number&of&females&aged&15 49&interviewed&in&the&survey&
The analysis was carried out in two phases: the national level where data from all
women aged 15- 49 years who participated in the study across all the regions were
included. The second stage included participants from only the Eastern and Upper
West regions of Ghana.
Descriptive statistics were presented in terms of proportions and 95% confidence
intervals. Rao-Scott χ2 test statistics was used to test for associations between the
independent characteristics and anaemia status of the women. A weighted binary
logistic-based multivariate decomposition technique [28] was used to quantify the
contribution of selected variables to the change/reduction in anaemia prevalence
between 2008 and 2014 at the national level and for the Eastern and Upper West
regions.
Sensitivity analysis was carried out using haemoglobin concentration to test the
robustness of the results of the decomposition analysis. The results of the
decomposition analysis were presented as endowment and coefficient effects. The
endowment effect explains how much the changes in the level of the explanatory
variables between 2008 and 2014 contribute to the observed difference in anaemia
and mean Hb level between 2008 and 2014. The coefficient effect measures the
https://doi.org/10.18697/ajfand.116.23075
22253
contribution of differences in the coefficients (including differences in the intercept)
to the observed difference in the mean Hb level between 2008 and 2014.
The interaction term accounts for the fact that differences in endowments and
coefficients exist simultaneously between 2008 and 2014. Following binary
analysis, the variables -household wealth index, current age, maternal educational
level, hormonal contraceptive use and BMI were selected for decomposition
analysis for the national level and Eastern Region. For the Upper West Region,
variables selected were household access to improved water sources, maternal
education, and BMI. Contributions of each covariate were reported in terms of
coefficients and percentages.
RESULTS AND DISCUSSION
The findings provide background characteristics of the study population and the
changes in anaemia prevalence between 2003 to 2014 among selected
households and individual-levelled characteristics. The drivers (variables) of the
changes and decline in anaemia prevalence and haemoglobin concentration
between 2008 and 2014 for the national level, Eastern and Upper West regions of
Ghana are also presented.
Selected household and maternal/individual-levelled characteristics
The mean age of the household heads was 43.8 (± 13.7) years and a higher
proportion (61.6%) of households were headed by males. About four out of every
ten (44.4%) households had less than 5 members. More than two-thirds of the
households had access to improved drinking water (87.7%) Use of insecticide-
treated bednets, improved over the years from 2003 (19.3%) to 2014 (75.1%).
The mean age of the women was 29.2 (± 9.4) years. Close to half (47.6%) of the
women were currently married. More than half of the women had up to secondary
level education. Sixty percent of the women had normal body size while three in
every ten women were either overweight (BMI>25kg/m^2) or obese
(BMI>30kg/m^2). Most of the women had between one and four children each.
About 20% were currently breastfeeding. Appendix 2 provides further details of the
household and maternal/individual-levelled characteristics.
Levels, trends, and differences in maternal anaemia status between surveys
The prevalence of maternal anaemia at the national level has been fluctuating over
the past decades (Figure 1). In 2003, the prevalence was 44.6% [95%CI:42.8,46.4]
but increased to 58.7% [95%CI:56.7,60.7] in 2008. Thus, there was a 14.1% points
https://doi.org/10.18697/ajfand.116.23075
22254
increase in anaemia among women between 2003 to 2008. In 2014, the level of
maternal anaemia declined to 42.4% [95%CI: 40.5,44.2], thus, a 16.3% points
reduction from 2008. The reduction in maternal anaemia between 2003 and 2014
was 2.2% points (Appendices 3 and 4).
Overall, except for the sex of the household head, marital status, ethnicity, parity,
and the number of children alive, the prevalence of maternal anaemia was
significantly different across all levels of the variables studied (p<0.05).
Consistently, the prevalence of maternal anaemia was relatively lower among
women who use hormonal contraception. The prevalence of maternal anaemia
decreased among WRA with higher educational levels across survey years.
Appendix 3 provides details of the prevalence of anaemia among selected
households and individual-levelled characteristics, and Appendix 4, the changes in
reduction over the survey periods of study.

Drivers of reduced anaemia (decomposition analysis results)
The multivariate decomposition analysis identified the drivers of the reduction in
maternal anaemia prevalence between the survey periods 2008 and 2014. At the
national level, changes in the characteristics (endowments) of the participants
were associated with a reduction in maternal anaemia by 0.01471 representing

9.04% (p<0.001) whiles the size of the effect of all the characteristics (coefficients)
was associated with a decline of 0.14806 representing 90.96%. Changes in the
proportion of hormonal contraceptive use were associated with a 1.5% reduction in
maternal anaemia. Changes in the distribution of maternal BMI status were
associated with a 5.05% reduction in maternal anaemia. In the sensitivity analysis
using haemoglobin concentration as the outcome, 9.8 % of the changes in
characteristics (endowments) were associated with a reduction in maternal
anaemia by 0.047 whiles the size of the effect (coefficients) was associated with a
reduction of 0.592 representing 90.2%. Details of the decomposition analysis are
shown in Table 1 and Appendix 7.
In the Eastern Region, the variables studied were associated with changes in the
distribution of the characteristics (endowment) to the decline of anaemia by
0.01164 representing a 5.99% reduction while the size of the effect of all the
characteristics (coefficients) was associated with a decline by 0.18271
representing 94.01% of maternal anaemia between 2008 and 2014 survey periods.
Changes in the proportion of hormonal contraceptive use were associated with a
0.002 reduction (1.03%) of maternal anaemia. In the sensitivity analysis using
haemoglobin concentration as the outcome, 6.1 % of the changes in
characteristics (endowments) were associated with a reduction in maternal
anaemia by 0.015 whiles the size of the effect (coefficients) was associated with a
reduction of 0.601 representing 93.9% (Appendices 5 and 7).
In the decomposition analysis for the Upper West Region, the variables studied
were associated with a 0.0173 (5.48%; p<0.050) reduction to changes in the
distribution of the characteristics (endowment) of maternal anaemia between 2008
and 2014; whiles the size of the effect of all the characteristics (coefficients) was
associated with 0.29836 (94.52%) decline (Table 3). Changes in the proportion of
access to improved water sources were associated with a 1.09% reduction in
maternal anaemia. Maternal education was associated with 1.49% of the reduction
in maternal anaemia. For the sensitivity analysis using haemoglobin concentration
as the outcome, 6.7 % of the changes in characteristics (endowments) were
associated with a reduction of maternal anaemia by 0.019 whiles the size of the
effect (coefficients) was associated with a reduction of 1.149 representing 93.3%
(Appendices 6 and 7).
The current study examined and described the drivers of reduced anaemia
prevalence among WRA at the national and sub-national levels in the northern and
southern parts of Ghana using data from the Ghana Demographic and Health
Surveys for 2003, 2008 and 2014. Determining the drivers at the national and sub-
https://doi.org/10.18697/ajfand.116.23075
22256
national levels provides an opportunity to understand the variance at the sub-
national level. The findings will inform sub-national specific interventions to
promote the reduction of anaemia among WRA.
The drivers associated with a decline in anaemia between 2008 and 2014 at the
national and sub-national levels comprised both household and maternal
characteristics similar to other studies [21,24,25]. At the national level, the factors
included household wealth index and maternal level characteristics (maternal age
and education, BMI, and hormonal contraceptive use). At the sub-national level -
Eastern Region, the decline in anaemia among WRA was linked to household
wealth index, maternal age, maternal educational level, BMI, and hormonal
contraceptive use. In the Upper West Region, the key drivers explaining the
decline in anaemia prevalence included household access to improve water
sources, maternal education, and BMI.
Household wealth index is a measure of the socioeconomic status (SES) of the
household, the ability of the household to access basic needs and healthcare
services and provide for the needs of household members. It was identified as a
driver of the decline in anaemia at the national and the Eastern Region. Over the
period of the study, socioeconomic changes [29] were observed in the country.
These included an increase in access to information and communication
technology (ICT) [30], poverty reduction, improved trade policies, improved
healthcare infrastructure (expansion in Community-based Health and Planning
Services (CHPS)) [15,31], increasing access to healthcare services; increase in
water, sanitation and hygiene (WASH) services (drilling of boreholes and improved
toilet facilities) [32,33]; and provision of agricultural inputs and services [34].
Other services were an increase in social safety net programmes such as
Livelihood Empowerment Against Poverty (LEAP), the school-feeding programme,
health insurance, the distribution of iron-folate supplements to pregnant women
and adolescent girls, and provision of Sulfadoxine/pyrimethamine (SP) for
presumptive treatment of malaria during pregnancy [35]. These were enabled
through government, development partners and individual resources who worked
with community leaders to improve the livelihoods of households in the regions
[32,36]. All these changes were likely to have influenced household socioeconomic
status. According to the 2021 Population and Housing Census [29], the Eastern
Region with a wider population experienced more socioeconomic changes and
could therefore explain the changes observed as compared to the Upper West
Region. Household wealth index was noted to influence a decline in anaemia
among WRA in other developing settings [10,25].
https://doi.org/10.18697/ajfand.116.23075
22257
The changes in the SES [20,37] of the country preceding and during the period of
study could explain increased access to services including healthcare, and WASH
which could have led to better health outcomes such as decline in anaemia noted
in this study. For example, there were expansion in access to improved toilet
facilities and drilling of boreholes from the activities of non-governmental
organisations such as World Vision [38]. These interventions might likely have
improved household livelihoods and reduced the risk of infections and sickness
which could compromise the nutrition of women as observed by Kothari et al. [21].
The evidence of an association between selected WASH indicators and anaemia is
well established [10,21,25]. Kothari et al. [21] observed that in both WRA and
children, the presence of water in the household appeared to be protective against
anaemia (lower anaemia prevalence and odds). Nguyen et al., [25] also reported a
9% decline in anaemia prevalence among pregnant women due to improved
sanitation in India. Heckert et al., [24] noted a 12% decline in anaemia prevalence
among WRA in Tanzania due to a reduction in the percentage of households using
open defecation. These studies highlight the benefit of integrating WASH into
nutrition interventions specific to addressing anaemia, and therefore suggest an
increased access to these services to aid in the reduction of anaemia among
WRA.
Hormonal contraceptive use as a driver, reduces the risk of anaemia among WRA
possibly through a decrease in monthly menstrual cycle flow and birth spacing [10].
For this study, at the national level, the expansions in healthcare infrastructure [31]
and access to healthcare services such as family planning which could have
impacted access to hormonal contraceptives by WRA and therefore its uptake,
influencing birth spacing. The Eastern Region [39] was observed to have benefited
a lot from sexual reproductive health (SRH) services support such as enhanced
staff training and women’s education on SRH and promotion of free contraceptives
from donors and development partners which could explain the use of hormonal
contraceptives in the Eastern Region as compared to the Upper West. Hormonal
contraceptive use was also noted in other studies to be a driver of anaemia decline
among WRA [19,24,40]. Lakew et al. [40] from Ethiopia noted that contraceptives
use among lactating women was protective against anaemia (-7.7%). Heckert et al.
[24] study in Tanzania also reported a 30% change in anaemia prevalence a result
of contraceptive use.
A higher educational level among WRA as a driver of the decline in anaemia was
noted in other studies [24,25]. An increase in education was likely to have led to a
better understanding of anaemia and its associated factors among WRA. With an
https://doi.org/10.18697/ajfand.116.23075
22258
increase in the SES of the country and improved ICT, WRA were better positioned
to increase their knowledge about anaemia. Increased access to healthcare and
possible visits to the health facility and interaction with health staff were likely to
have informed dietary choices about the consumption of iron-rich foods, and
supplementation, therefore leading to the decline observed. Nguyen et al. [25]
noted a 24% decline in anaemia among WRA due to improved maternal education.
Heckert et al., [24] also noted a 36% change in anaemia among WRA as a result
of improved maternal education.
Increased maternal age was a driver of reduced anaemia among WRA. Exposure
to activities, projects and interventions as the woman ages were likely to have
enhanced the woman’s knowledge about anaemia and empowered her to make
informed decisions about her dietary habits, and other issues such as family
planning and birth spacing. This is consistent with literature [10].
Body mass index was a driver of reduced anaemia at the national and sub-national
levels. Women who were normal or overweight/ obese had reduced anaemia
compared to underweight women. With improvement in the SES of the country
(ICT, reduced poverty), these could have informed dietary habits and patterns and
was likely to have led to a decline in anaemia. The findings from this study are
similar to those from other studies [14,15,35].
The findings of this study demonstrate the roles of nutrition actions and
interventions (nutrition-specific and nutrition-sensitive) in addressing anaemia
among WRA. The evidence shows addressing the burden of anaemia among WRA
requires multiple actions across different sectors [10]. It also shows evidence of
actions and initiatives of the Government of Ghana and development partners that
precede the decade under investigation to help explain the observed decline in
anaemia among WRA. For example, the development and publication of the
National Plan of Action on Food and Nutrition 1995-2002 by the Government of
Ghana to address malnutrition served several ministries aside from health
(nutrition).
The current study had some limitations. The study used secondary data from
cross-sectional studies for analysis. Data for cross-sectional studies are carried out
at a single time point and are subject to respondent recall bias therefore it is
challenging to establish causality as the outcome and exposure variables are
measured at the same time. Secondly, the secondary data did not include
variables such as haemoglobin measurement of pregnant women at registration
and delivery, and malaria intermittent preventive treatment (IPT) doses which are
https://doi.org/10.18697/ajfand.116.23075
22259
important indicators about anaemia among WRA to inform decision-making and
planning of interventions. And, therefore, recommend the collection of these data
in future surveys. Thirdly, the current study used data from the last DHS -2014 in
the decomposition analysis to determine the drivers of the decline. It is likely, there
have been changes in the explanatory variables up to date which might help
explain the decline or otherwise. Despite these limitations, to the best of our
knowledge, this study is the first of its kind to examine, identify and describe the
drivers of anaemia reduction among WRA at the national and sub-national levels in
Ghana. The use of a large nationally representative dataset increased the study
sample size and power. The use of the multivariate decomposition technique, a
rigorous method enabled the determination of the effect of explanatory variables
contributing to the decline observed.
CONCLUSION
The current study provides evidence about the drivers of reduced anaemia
prevalence at the national and sub-national levels in Ghana. The decomposition
analysis identified changes at the national level in household wealth index,
maternal age and education, BMI, and hormonal contraceptive use as key drivers
of change. At the sub-national levels - Eastern Region, household wealth index,
maternal age and education, BMI, and the use of hormonal contraceptives were
the drivers. In the Upper West Region, household access to improved water
sources, maternal education, and BMI were the noted drivers. The observed
changes in decline in anaemia prevalence could be attributed to improvement in
the SES of Ghana and policy and programme interventions such as LEAP, school
feeding, and health insurance. Other interventions are WASH, iron-folate
supplementation for pregnant and adolescent girls and food fortification. Working
engagement across the different sectors from the national to the sub-national level
between government and development partners implementing these interventions
was also a contributory factor. Further declines in anaemia reduction require more
multisectoral coordination and targeted interventions which address the drivers of
anaemia among WRA reduction. Identifying the drivers of anaemia reduction
among WRA at the national and sub-national levels has highlighted the context-
specific drivers needed to tackling anaemia prevalence. It provides an opportunity
to understand the variance at the sub-national level which may inform sub-national
specific interventions to promote the reduction of anaemia among WRA.

... In Ghana, anaemia in WRA has decreased from 59% in 2008 to 42% in 2014. Tetteh et al. 34 observed improvements in the wealth index of families as a result of a variety of characteristics including the mother's age, education, usage of hormonal contraception, and body mass index (BMI) which partially explained the decline in anaemia among WRA over the years. The household wealth index, a measure of the family's socioeconomic status (SES), the capacity of the household to obtain basic needs and healthcare services, and the ability of the household to provide for the needs of household members, was critical to the lowering prevalence of WRA in Ghana. ...
... However, there has been a paucity of research on the detrimental health effects of biomass smoke exposure 35,36 , where a significant proportion of the population use firewood exclusively or in combination with LPG or kerosene for fuel/energy. The studies of Tetteh et al. 34 and Armo-Annor et al. 37 are the only known studies that explored solid fuel use-related anaemia among women. Even so, the study of Tetteh et al. 34 considered the drivers of anaemia reduction among WRA, with less emphasis on the effect of cooking fuel use on anaemia risk, while focusing on The Eastern and Upper West regions of Ghana. ...

In low- and middle-income countries, indoor air pollution (IAP) is a serious public health concern, especially for women and children who cook with solid fuels. IAP exposure has been linked to a number of medical conditions, including pneumonia, ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer, and anaemia. Around 500 million women of reproductive age (WRA) suffer from anaemia globally, with an estimated 190 million cases in sub-Saharan Africa (SSA). This study, which is based on prior research, investigates the relationship between IAP exposure and anaemia among WRA in Ghana. A diverse sample of 2,406 WRA living in Ghana were interviewed, of which 58.06% were anaemic and used high-pollutant fuels for cooking. Age, place of residence, region, education level, religion, ethnicity, wealth index, type of drinking water, type of toilet facility, and type of cooking fuels were all found to be significantly linked with anaemic state by bivariate analysis. Type of cooking fuels utilized, age, region of residence, and the type of residence were shown to be significant predictors of anaemia status using sequential binary logit regression models. The results emphasise the critical need for efforts to promote the usage of clean cooking fuel in an attempt to lower anaemia prevalence in Ghana. To reduce dependency on solid fuels for cooking, initiatives should promote the use of cleaner cooking fuels and enhance the socioeconomic status of households. These interventions could have significant public health effects by reducing the burden of anaemia and improving maternal and child health outcomes due to the prevalence of anaemia among WRA. Overall, this study sheds light on the relationship between IAP exposure and anaemia in Ghana and highlights the demand for focused public health initiatives to address this serious health problem.

Introduction previous studies in African populations have not extensively described the spectrum of thyroid dysfunction using the profile of thyroid hormones. Although iodine deficiency is a common thyroid disorder in Africa, it does not represent the entire spectrum of thyroid dysfunction seen in patients. This retrospective study aimed to describe the spectrum of thyroid dysfunction among patients seen at the Korle-Bu Teaching Hospital (KBTH), a tertiary care hospital in Accra, Ghana. Methods a retrospective analysis of medical records of all consultations on thyroid disorders seen at the Internal Medicine Department of KBTH between January 2019 and December 2021 was conducted. Information on patient demographics, and thyroid hormone profiles (triiodothyronine - FT3, thyroxine - FT4, and thyroid stimulating hormone - TSH) were extracted and subjected to descriptive statistics. The thyroid hormone profiles of the subjects were analyzed and classified into thyroid dysfunction categories using guidelines from the American Thyroid Association (ATA). Results out of the 215 patients with thyroid disorders enrolled, 85.1% (n=183) were females and 14.9% (n=32), were males. The mean age of patients was 45±14 years, with most of the patients within the age range of 31-50 years (49.3%; n=106). The most reported thyroid function dysfunction was primary hyperthyroidism (57.7%), followed by primary hypothyroidism (22.3%), subclinical hyperthyroidism (9.3%), euthyroid sick syndrome (6.5%), and subclinical hypothyroidism (4.6%) respectively. Conclusion primary hyperthyroidism was the most commonly diagnosed thyroid dysfunction. Hyperthyroidism has been associated with cardiac morbidity and mortality. Timely interventions are required to reduce the morbidity risks and burden associated with the hyperthyroid state.

Building the capacity of a new generation of scholars is both a necessary and an exciting quest. It is an opportunity to be intentional in passing on the baton of ‘know-how’ (knowledge and experience) and ‘know-do’ (competence and leadership) in a way that ensures that future generations of scholars will generate the scientific evidence to support policy and program decisions make the world a better place. This special issue of AJFAND includes output from scholars involved in capacity building activities that have been possible through more than 20 years of research and training partnership between the University of Ghana, McGill University, and rural institutions in Ghana. The two Universities have collaborated on multiple projects (the RIING, ENAM, Nutrition Links, and LInkINg UP projects) that have developed the capacity of young trainees while improving maternal and child nutrition in rural settings [1-3].

Information on patient demographics, and thyroid hormone profiles (triiodothyronine - FT3, thyroxine - FT4, and thyroid stimulating hormone - TSH) were extracted and subjected to descriptive statistics. Thyroid hormone profiles of subjects were analyzed and classified into thyroid dysfunction categories using guidelines of the American Thyroid Association (ATA). Results: Out of the 215 patients with thyroid disorders enrolled, 85.1% (n = 183) were females and 14.9% (n = 32), males. The mean age of patients was 45±14 years, with most of the patients within the age range of 31-50 years (49.3%; n=106). The most reported thyroid function dysfunction was primary hyperthyroidism (57.7%), followed by primary hypothyroidism (22.3%), subclinical hyperthyroidism (9.3%), euthyroid sick syndrome (6.5%), and subclinical hypothyroidism (4.6%) respectively. Conclusion: Primary hyperthyroidism was the most commonly diagnosed thyroid dysfunction. Hyperthyroidism has been linked with cardiac morbidity and mortality. Timely interventions are required to reduce the morbidity risks and burden associated with the hyperthyroid state.

13 years after the first Lancet Series on maternal and child undernutrition, we reviewed the progress achieved on the basis of global estimates and new analyses of 50 low-income and middle-income countries with national surveys from around 2000 and 2015. The prevalence of childhood stunting has fallen, and linear growth faltering in early life has become less pronounced over time, markedly in middle-income countries but less so in low-income countries. Stunting and wasting remain public health problems in low-income countries, where 4·7% of children are simultaneously affected by both, a condition associated with a 4·8-times increase in mortality. New evidence shows that stunting and wasting might already be present at birth, and that the incidence of both conditions peaks in the first 6 months of life. Global low birthweight prevalence declined slowly at about 1·0% a year. Knowledge has accumulated on the short-term and long-term consequences of child undernutrition and on its adverse effect on adult human capital. Existing data on vitamin A deficiency among children suggest persisting high prevalence in Africa and south Asia. Zinc deficiency affects close to half of all children in the few countries with data. New evidence on the causes of poor growth points towards subclinical inflammation and environmental enteric dysfunction. Among women of reproductive age, the prevalence of low body-mass index has been reduced by half in middle-income countries, but trends in short stature prevalence are less evident. Both conditions are associated with poor outcomes for mothers and their children, whereas data on gestational weight gain are scarce. Data on the micronutrient status of women are conspicuously scarce, which constitutes an unacceptable data gap. Prevalence of anaemia in women remains high and unabated in many countries. Social inequalities are evident for many forms of undernutrition in women and children, suggesting a key role for poverty and low education, and reinforcing the need for multisectoral actions to accelerate progress. Despite little progress in some areas, maternal and child undernutrition remains a major global health concern, particularly as improvements since 2000 might be offset by the COVID-19 pandemic.

Stunting in Ghana is associated with rural communities, poverty, and low education; integrated agricultural interventions can address the problem. This cluster randomized controlled trial tested the effect of a 12-month intervention (inputs and training for poultry farming and home gardening, and nutrition and health education) on child diet and nutritional status. Sixteen clusters were identified and randomly assigned to intervention or control; communities within clusters were randomly chosen, and all interested , eligible mother-child pairs were enrolled (intervention: 8 clusters, 19 communities, and 287 households; control: 8 clusters, 20 communities, and 213 households). Intention to treat analyses were used to estimate the effect of the intervention on endline minimum diet diversity (≥4 food groups), consumption of eggs, and length-forage (LAZ)/height-forage (HAZ), weight-forage (WAZ), and weight-for-length (WLZ)/ weight-for-height (WHZ) z-scores; standard errors were corrected for clustering. Children were 10.5 ± 5.2 months (range: 0-32) at baseline and 29.8 ± 5.4 months (range: 13-48) at endline. Compared with children in the control group, children in the intervention group met minimum diet diversity (adjusted odds ratio = 1.65, 95% CI [1.02, 2.69]) and a higher LAZ/HAZ (β = 0.22, 95% CI [0.09, 0.34]) and WAZ (β = 0.15, 95% CI [0.00, 0.30]). Sensitivity analyses with random-effects and mixed-effects models and as-treated analysis were consistent with the findings. There was no group difference in WLZ/WHZ. Integrated interventions that increase access to high-quality foods and nutrition education improve child nutrition.

Poor dietary quality and nutritional status among young children is common in rural low‐income households in Upper Manya Krobo District (UMKD), Ghana. Consumption of animal source foods can improve diet and growth outcomes. The Nutrition Links Project is a 5‐y capacity‐building project to improve nutrition and well‐being of vulnerable populations in UMKD. The project includes a small cluster randomized controlled trial that provides home gardening, health, nutrition education, and poultry entrepreneurial activities for caregivers who had a 0‐to 12‐mo‐old infant and were living in the intervention communities at enrollment (IN; n=102). Caregivers in the control (CT) communities (n=228) receive only the standard‐of‐care for nutrition, health, and agricultural extension provided by government staff. This on‐going study seeks to improve the diets and growth outcomes of young children, partly through increased egg consumption. For this analysis, longitudinal data comparing children's egg consumption during the previous day, were collected from caregivers at baseline and at the first follow‐up [IN (n=102); CT (n=228)], approximately 7 months after the intervention was implemented. At baseline, when infants were 8.7±4.1 mo old, few consumed eggs [IN (15.5%) and CT (20.8%)]. By the first follow‐up, there was a statistically significant difference in the percent of children consuming eggs (IN (28.4%) vs. CT (52.6%); P<0.001). The lower intake of eggs among IN children occurred despite the fact that IN caregivers had an increased access to eggs from the poultry enterprise. The negative effect during the early months of the intervention may reflect caregivers placing greater emphasis on egg sales for income and success of their poultry enterprise rather than home consumption. In‐depth evaluation is needed to better understand caregivers’ behaviours and to determine the project effect on the total diet. Nutrition education activities continue to encourage use of eggs as well as diverse nutrient‐rich foods in UMKD children's diets to ensure the nutrition‐sensitive agriculture intervention achieves the expected objective of improving diets and nutritional status of project participants.
