Article: Risk Factors for Preterm Birth and Small-for-gestational-age Births among Canadian Women.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Preterm births (PTB) and small-for-gestational-age (SGA) births are distinct but related pregnancy outcomes, with differing aetiologies and short and long-term morbidities. Few studies have compared a broad array of predictors among these two outcomes. The purpose of this study was to compare risk factors for PTB and SGA births using a national sample of Canadian women. METHODS: We analysed data from the Canadian Maternity Experiences Survey (n = 6421). Mothers were ≥15 years of age, gave birth to a singleton infant and were living with their infant at the time of the interview (between 5 and 14 months post-partum). Backward stepwise multivariable logistic regression models were constructed for each outcome. RESULTS: Risk profiles for the two outcomes had both differences and similarities. Risk factors specific to PTB were education less than high school, having a previous medical condition, developing a new medical condition or health problem during pregnancy, being a primigravida, or being a multigravida with a previous PTB or a previous miscarriage or abortion. Risk factors unique to SGA were low pre-pregnancy body mass index (<18 kg/m(2) ), smoking during pregnancy and being a recent immigrant. Risk factors for both outcomes included low weight gain during pregnancy (<9.1 kg), short stature (<155 cm) and reporting life as 'very stressful' in the year prior to birth of the baby. CONCLUSION: A greater understanding of the risk factors related to PTB and SGA may help to reduce the prevalence of these conditions and the associated risk of infant mortality and morbidity.Paediatric and Perinatal Epidemiology 01/2013; 27(1):54-61. · 2.31 Impact Factor -
Article: Advanced maternal age and risk perception: A qualitative study.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Advanced maternal age (AMA) is associated with several adverse pregnancy outcomes, hence these pregnancies are considered to be "high risk." A review of the empirical literature suggests that it is not clear how women of AMA evaluate their pregnancy risk. This study aimed to address this gap by exploring the risk perception of pregnant women of AMA. METHODS: A qualitative descriptive study was undertaken to obtain a rich and detailed source of explanatory data regarding perceived pregnancy risk of 15 women of AMA. The sample was recruited from a variety of settings in Winnipeg, Canada. In-depth interviews were conducted with nulliparous women aged 35 years or older, in their third trimester, and with singleton pregnancies. Interviews were recorded and transcribed verbatim, and content analysis was used to identify themes and categories. RESULTS: Four main themes emerged: definition of pregnancy risk, factors influencing risk perception, risk alleviation strategies, and risk communication with health professionals. CONCLUSIONS: Several factors may influence women's perception of pregnancy risk including medical risk, psychological elements, characteristics of the risk, stage of pregnancy, and health care provider's opinion. Understanding these influential factors may help health professionals who care for pregnant women of AMA to gain insight into their perspectives on pregnancy risk and improve the effectiveness of risk communication strategies with this group.BMC Pregnancy and Childbirth 09/2012; 12(1):100. · 2.83 Impact Factor -
Article: Comparison of perception of pregnancy risk of nulliparous women of advanced maternal age and younger age.
[show abstract] [hide abstract]
ABSTRACT: Introduction: Over the last 3 decades, the proportion of women who have delayed childbearing into their mid 30s and early 40s has been increasing. Because advanced maternal age (AMA) is associated with several adverse maternal, fetal, and neonatal outcomes, these pregnancies are considered to be "high risk." Research indicates that pregnancy risk perception is an important factor in pregnant women's health care use and decision making during pregnancy. The objectives of this study were to compare risk perception in pregnant women of AMA (aged 35 years or older) with that of younger women and to explore the relationship between perception of pregnancy risk and selected variables. Methods: A sample of 159 nulliparous pregnant women (105 aged 20-29 years and 54 aged 35 years or older) was recruited from a variety of settings in Winnipeg, Manitoba, Canada. Women were asked to complete questionnaires to assess perception of pregnancy risk, risk knowledge, pregnancy-related anxiety, perceived control, health status, and medical risk. Results: Women of AMA had higher education levels, were more likely to work during pregnancy, and had higher medical risk scores than younger women. Women of AMA perceived higher pregnancy risk for both themselves and their fetuses than did younger women. They rated their risks of cesarean birth, dying during pregnancy, preterm birth, and having a newborn with a birth defect or one needing admission to a neonatal intensive care unit higher than those of younger women. There were no significant differences between the 2 age groups in pregnancy-related anxiety, knowledge of risk, perceived control, and health status. Discussion: Women of AMA have a higher perception of pregnancy risk than younger women, regardless of their medical risk. This evidence suggests that incorporating discussions of pregnancy risk into prenatal care visits may assist pregnant women of AMA to make more informed choices, reduce anxiety, and avoid unnecessary interventions.Journal of midwifery & women's health 09/2012; 57(5):445-53. · 1.13 Impact Factor -
Article: Prevalence of Abuse and Violence Before, During, and After Pregnancy in a National Sample of Canadian Women.
[show abstract] [hide abstract]
ABSTRACT: Objectives. We describe the prevalence of abuse before, during, and after pregnancy among a national population-based sample of Canadian new mothers. Methods. We estimated prevalence, frequency, and timing of physical and sexual abuse, identified category of perpetrator, and examined the distribution of abuse by social and demographic characteristics in a weighted sample of 76 500 (unweighted sample = 6421) Canadian mothers interviewed postpartum for the Maternity Experiences Survey (2006-2007). Results. Prevalence of any abuse in the 2 years before the interviews was 10.9% (6% before pregnancy only, 1.4% during pregnancy only, 1% postpartum only, and 2.5% in any combination of these times). The prevalence of any abuse was higher among low-income mothers (21.2%), lone mothers (35.3%), and Aboriginal mothers (30.6%). In 52% of the cases, abuse was perpetrated by an intimate partner. Receiving information on what to do was reported by 61% of the abused mothers. Conclusions. Large population-based studies on abuse around pregnancy can facilitate the identification of patterns of abuse and women at high risk for abuse. Before and after pregnancy may be particularly important times to monitor risk of abuse.American Journal of Public Health 08/2012; 102(10):1893-1901. · 3.93 Impact Factor -
Article: Neighbourhood context and abuse among immigrant and non-immigrant women in Canada: findings from the Maternity Experiences Survey.
[show abstract] [hide abstract]
ABSTRACT: To examine the relationship between neighbourhood deprivation and concentration of immigrants, and abuse among immigrant women versus non-immigrant women. Using data from the Canadian Maternity Experiences Survey (un-weighted sample N = 5,679 and weighted sample N = 68,719) linked to the neighbourhoods Census data, we performed contextual analysis to compare abuse prevalence among: immigrants ≤5 years, immigrants >5 years and Canadian-born. We identified two level effect modifiers: living in high (≤15 % of households at or below low-income cut-off- [LICO]) versus low-income (>15 % below LICO) neighbourhoods and living in high (≥25 %) versus low immigrant (<25 %) neighbourhoods. Individual socioeconomic position (SEP), family variables and neighbourhood SEP or percentage of immigrants were considered in different logistic regression models. Immigrant women were less likely to experience abuse even upon adjustment for individual SEP, family variables and neighbourhood characteristics. The protective effect of the neighborhood was stronger among immigrant women living in low-income and high immigrant neighborhoods, irrespective of length of stay in Canada. Policies and interventions to reduce abuse among immigrant women need to consider neighbourhood's SEP and concentration of immigrants.International Journal of Public Health 05/2012; 57(4):679-89. · 2.54 Impact Factor -
Article: Comparison of adolescent, young adult, and adult women's maternity experiences and practices.
[show abstract] [hide abstract]
ABSTRACT: Pregnant adolescents face unique challenges. Understanding the experiences, knowledge, and behaviors of adolescents during the pregnancy and postpartum periods may contribute to improvement of their maternity care. The purpose of this study was to compare the maternity experiences, knowledge, and behaviors of adolescent, young adult, and adult women by using a nationally representative sample. This study used data from the Canadian Maternity Experiences Survey (N = 6421). The weighted proportions of each variable were calculated by using survey sample weights. Logistic regression was used to estimate odds ratios. Bootstrapping techniques were used to calculate variance estimates for prevalence and 95% confidence intervals. Adolescents and young adults were more likely to experience physical abuse in the previous 2 years, initiate prenatal care late, not take folic acid before or during pregnancy, have poor prenatal health behaviors, have a lower cesarean delivery rate, have lower breastfeeding initiation and duration rates, experience more stressful life events, experience postpartum depression symptoms, and rate their infant's health as suboptimal than adult women. Adolescents were more likely to rate their own health as suboptimal. Adolescents have unique needs during pregnancy and postpartum. Health care professionals should seek to provide care in a manner that acknowledges these needs.PEDIATRICS 04/2012; 129(5):e1228-37. · 4.47 Impact Factor -
Article: Use of routine interventions in labour and birth in Canadian hospitals: comparing results of the 1993 and 2007 Canadian hospital maternity policies and practices surveys.
[show abstract] [hide abstract]
ABSTRACT: To compare policies and practices of routine interventions in labour and birth in Canadian hospitals in 1993 and 2007 and to describe trends regarding adherence to evidence-based guidelines. We used data from surveys of Canadian hospitals in 1993 and 2007 on routine maternity care practices and policies, including interventions in labour and birth. The response rate of hospitals in 1993 was 91% (523/572), and in 2007 it was 92% (323/353). In 1993, 65% of hospitals (335/516) had a policy that all women should have initial electronic fetal heart rate monitoring, and in 2007, 74% (235/319) had such a policy. In 1993, 55% of hospitals (284/516) used epidural anaesthesia as one of the methods for pain control, and in 2007, 87% of hospitals (278/318) did so. In 1993, 37% of hospitals (193/521) had a "no enema/suppository" policy on admission, and in 2007, 88% (282/322) did. In 1993, 87% of hospitals (450/516) had a policy encouraging the presence of both the woman's partner and other labour support people in the room during the course of labour; in 2007, 80% (259/323) did. In 1993, hospitals estimated that 62% of primiparous women and 44% of multiparous women had an episiotomy in their units. In 2007, the episiotomy rate, irrespective of parity, was 17%. In 1993, 20% of hospitals (98/498) had a policy specifying the length of the second stage of labour, and in 2007, 33% (101/307) had such a policy. Positive and negative trends in adherence to best practices were seen in policies and practices of routine interventions during labour and birth in Canadian hospitals between 1993 and 2007.Journal of obstetrics and gynaecology Canada: JOGC = Journal d'obstetrique et gynecologie du Canada: JOGC 12/2011; 33(12):1208-17. -
Article: Comparison of maternity experiences of Canadian-born and recent and non-recent immigrant women: findings from the Canadian Maternity Experiences Survey.
[show abstract] [hide abstract]
ABSTRACT: To compare the maternity experiences of immigrant women (recent, ≤ 5 years in Canada; non-recent > 5 years) with those of Canadian-born women. This study was based on data from the Canadian Maternity Experiences Survey of the Public Health Agency of Canada. A stratified random sample of 6421 women was drawn from a sampling frame based on the 2006 Canadian Census of Population. Weighted proportions were calculated using survey sample weights. Multivariable logistic regression was used to estimate odds ratios comparing recent immigrant women with Canadian-born women and non-recent immigrant women with Canadian-born women, adjusting for education, income, parity, and maternal age. The sample comprised 7.5% recent immigrants, 16.3% non-recent immigrants, and 76.2% Canadian-born women. Immigrant women reported experiencing less physical abuse and stress, and they were less likely to smoke or consume alcohol during pregnancy, than Canadian women; however, they were more likely to report high levels of postpartum depression symptoms and were less likely to have access to social support, to take folic acid before and during pregnancy, to rate their own and their infant's health as optimal, and to place their infants on their backs for sleeping. Recent and non-recent immigrant women also had different experiences, suggesting that duration of residence in Canada plays a role in immigrant women's maternity experiences. These findings can assist clinicians and policy-makers to understand the disparities that exist between immigrant and non-immigrant women in order to address the needs of immigrant women more effectively.Journal of obstetrics and gynaecology Canada: JOGC = Journal d'obstetrique et gynecologie du Canada: JOGC 11/2011; 33(11):1105-15. -
Article: The experience of pregnancy and birth with midwives: results from the Canadian maternity experiences survey.
[show abstract] [hide abstract]
ABSTRACT: In Canada maternity care is publicly funded, and although women may choose their care providers, choices may be limited. The purpose of this study was to compare perceptions of maternity outcomes and experiences of those who received care from midwives with those who received care from other providers. Based on the 2006 Canadian census, a random sample of women (n = 6,421) who had recently given birth in Canada completed a computer-assisted telephone interview for the Maternity Experiences Survey. The sample was stratified according to province or territory where birth occurred, age, rural or urban residence, and presence of other children in the home. Those who were 15 years of age and older, gave birth to a singleton baby, and were living with their infant were eligible for inclusion. Women whose primary prenatal providers were midwives had fewer ultrasounds and were more likely to attend prenatal classes and have at least five or more prenatal visits. They were also more likely to rate satisfaction with their maternity experience as "very positive" and be satisfied with information provided on a variety of pregnancy and birth topics if their primary prenatal provider was a midwife. They were almost half as likely to experience induction and 7.33 times more likely to experience a medication-free delivery. They were more likely to initiate and maintain breastfeeding at 3 and 6 months. Evidence shows that midwifery outcomes and levels of satisfaction meet or exceed Canadian maternity care standards. Facilitation of the continuing integration of midwives as autonomous practitioners throughout Canada is recommended. (BIRTH 38:3 September 2011).Birth 09/2011; 38(3):207-15. · 2.18 Impact Factor -
Article: Breastfeeding policies and practices in Canadian hospitals: comparing 1993 with 2007.
[show abstract] [hide abstract]
ABSTRACT: The Baby-Friendly Hospital Initiative (BFHI) promotes the World Health Organization International Code of Marketing of Breast-milk Substitutes (WHO Code) and the WHO/UNICEF's Ten Steps to Successful Breastfeeding (Ten Steps). The purpose of this study is to describe and compare maternity hospitals' adherence to the BFHI in 1993 and 2007 for Canada and for each province and territory. A survey of all Canadian maternity hospitals was conducted in 1993 and 2007 on routine maternity care practices and policies including infant feeding. The overall response rate was 91 percent (n = 523/572 hospitals) in 1993 and 92 percent (n = 323/353 hospitals) in 2007. Eighty-two percent (415/507) of hospitals in 1993 and 68 percent (198/292) in 2007 had exclusive contracts with formula companies. Fifty-eight percent (302/517) of hospitals in 1993 and 90 percent (289/322) in 2007 never gave breastfeeding mothers sample packs containing formula. Fifty-eight percent (296/507) in 1993 and 85 percent (273/321) in 2007 had written breastfeeding policies (Step 1); 97 percent (503/518) in 1993 and 99 percent (320/322) in 2007 allowed mothers to breastfeed, on cue, whenever the babies indicated an interest 24 hours a day (Step 8); 24 percent (126/519) in 1993 and 64 percent (206/321) in 2007 reported that they did not provide soothers (Step 9); 58 percent (297/513) in 1993 and 68 percent (215/316) in 2007 always offered information on breastfeeding support groups and/or advice at time of discharge (Step 10). In the 14 years separating the two surveys, Canadian maternity hospitals substantially improved their implementation of the WHO Code and their adherence to the WHO/UNICEF Ten Steps.Birth 09/2011; 38(3):228-37. · 2.18 Impact Factor -
Article: Comparison of demographic and obstetric characteristics of Canadian primiparous women of advanced maternal age and younger age.
[show abstract] [hide abstract]
ABSTRACT: The rate of pregnancy at advanced maternal age (AMA) has increased during recent decades. The purpose of this study is to compare demographic and obstetric characteristics of Canadian primiparous women of AMA with those aged 20 to 29 years. We conducted a secondary analysis of data collected through the national Maternity Experiences Survey (MES) of the Canadian Perinatal Surveillance System. The sample included 301 primiparous women aged 35 years or over and 1,564 primiparous women aged 20 to 29 years. Estimates of prevalence for each group and their odds ratios were calculated using sample weights of the survey, and variances were calculated using bootstrapping methods adjusting for sampling design and weights. Women of AMA were significantly more likely to be better educated, to have higher income, to be employed, and to continue to work until the end of pregnancy than younger women. They also reported having significantly more information on pregnancy, labour, and birth, and they were more likely to attend prenatal classes. They were more likely to have had a miscarriage or infertility treatment, to request or be offered a Caesarean section, and to have a higher rate of Caesarean section. There were no significant differences in rates of preterm birth, low birth weight, and small-for-gestational age infants. Pregnant women of AMA differ from younger women in demographic characteristics, knowledge level, and some health behaviours and pregnancy outcomes. The growing number of pregnancies at AMA indicates the need for developing appropriate care plans to address the specific needs of this group.Journal of obstetrics and gynaecology Canada: JOGC = Journal d'obstetrique et gynecologie du Canada: JOGC 08/2011; 33(8):820-9. -
Article: Factors associated with perceived stress and stressful life events in pregnant women: findings from the Canadian Maternity Experiences Survey.
[show abstract] [hide abstract]
ABSTRACT: Prenatal maternal stress has been linked to multiple adverse outcomes. Researchers have used a variety of methods to assess maternal stress. The purpose of this study was to explore and compare factors associated with stress in pregnancy as measured by perceived stress and stressful life events. We analyzed data from the Canadian Maternity Experiences Survey. A randomly selected sample of 8,542 women who had recently given birth was drawn from the 2006 Canadian Census. Women were eligible if they were at least 15 years of age, had delivered a live, singleton infant, and were living with their infant at the time of the interview (5-14 months postpartum). Prevalence estimates and odds ratios were calculated using sample weights of the survey and their variances were calculated using bootstrapping methods. Bivariate analyses identified statistically significant factors associated with each stress measure. Backward stepwise multivariate logistic regression models were constructed. A total of 6,421 women (78%) participated in the computer assisted telephone interview. Twelve percent of women experienced high levels of perceived stress and 17.1% reported having three or more stressful life events in the year prior to the birth of their baby. In the final model, psychosocial variables were associated with both outcomes, whereas demographic factors were associated only with life event stress. Different factors contributed to perceived stress and life event stress, suggesting that these concepts measure different aspects of stress. These findings can inform routine psychosocial risk assessment in pregnancy.Maternal and Child Health Journal 12/2010; 16(1):158-68. · 2.24 Impact Factor -
Article: Birth outcomes and infant mortality among First Nations Inuit, and non-Indigenous women by northern versus southern residence, Quebec.
[show abstract] [hide abstract]
ABSTRACT: In circumpolar countries such as Canada, northern regions represent a unique geographical entity climatically, socioeconomically and environmentally. There is a lack of comparative data on birth outcomes among Indigenous and non-Indigenous subpopulations within northern regions and compared with southern regions. A cohort study of all births by maternal mother tongue to residents of northern (2616 First Nations (North American Indians), 2388 Inuit and 5006 non-Indigenous) and southern (2563 First Nations, 810,643 non-Indigenous) Quebec, 1991-2000. Compared with births to southern non-Indigenous mother tongue women, births to northern women of all three mother tongue groups were at substantially elevated risks of infant death (adjusted OR (aOR) 1.7-2.9), especially postneonatal death (aOR 2.2-4.4) after controlling for maternal education, age, marital status and parity. The risk elevation in perinatal death was greater for southern First Nations (aOR 1.6) than for northern First Nations (aOR 1.2). Infant macrosomia was highly prevalent among First Nations in Quebec, especially in the north (31% vs 24% in the south). Within northern regions, Inuit births were at highest risk of preterm delivery (aOR 1.4) and infant death (aOR 1.6). All northern infants (First Nations, Inuit or non-Indigenous) were at substantially elevated risk of infant death in Quebec, despite a universal health insurance system. Southern First Nations newborns have not benefited from the more advanced perinatal care facilities in southern regions. Environmental influences may partly account for the very high prevalence of macrosomia among First Nations in northern Quebec.Journal of epidemiology and community health 11/2010; 66(4):328-33. · 3.04 Impact Factor -
Article: Advanced maternal age and the risk of cesarean birth: a systematic review.
[show abstract] [hide abstract]
ABSTRACT: The increasing pregnancy rate at advanced maternal age is contemporaneous with the increasing rate of cesarean birth. Several studies have found that advanced maternal age is a risk factor for cesarean birth. The objective of this systematic review was to assess the relationship between advanced maternal age and cesarean birth among nulliparous and multiparous women. To identify relevant studies, we searched the literature for articles published from January 1, 1995 to March 1, 2008, using Medline, EMBASE, PsychINFO, and CINAHL. We also hand-searched the bibliographies of retrieved articles to identify additional related studies. We included all cohort studies and all case-control studies that examined this association in developed countries. The Cochrane Collaboration's Review Manager software (5.0) was used to summarize the data. Twenty-one studies met the inclusion criteria and were included in the review. All studies demonstrated an increased risk of cesarean birth among women at advanced maternal age compared with younger women, for both nulliparas and multiparas (relative risk varied from 1.39 to 2.76). Because we found extreme heterogeneity (both statistical and clinical) among the included studies, we did not provide a pooled estimate of the risk of cesarean birth. All included studies illustrated an increased risk of cesarean birth among older women. Fifteen studies adjusted this association for potential confounders, which suggests that a valid and independent association is likely to exist between advanced maternal age and cesarean birth. However, the associated factors for this increased risk are not totally understood in the literature.Birth 09/2010; 37(3):219-26. · 2.18 Impact Factor -
Article: Birth outcomes and infant mortality by the degree of rural isolation among first nations and non-first nations in Manitoba, Canada.
[show abstract] [hide abstract]
ABSTRACT: It is unknown whether rural isolation may affect birth outcomes and infant mortality differentially for Indigenous versus non-Indigenous populations. We assessed birth outcomes and infant mortality by the degree of rural isolation among First Nations (North American Indians) and non-First Nations populations in Manitoba, Canada, a setting with universal health insurance. A geocoding-based birth cohort study of 25,143 First Nations and 125,729 non-First Nations live births to Manitoban residents, 1991-2000. Degree of rural isolation was defined by an indicator of urban influence (no, weak, moderate/strong) based on the percentage of the workforce commuting to urban areas. Preterm birth and low birth weight rates were somewhat lower in all rural areas regardless of the degree of isolation as compared to urban areas for both First Nations and non-First Nations. Infant mortality rates were not significantly different across areas for First Nations (10.7, 9.9, 7.9, and 9.7 per 1,000 in rural areas with no, weak, moderate/strong urban influence, and urban areas, respectively), but rates were significantly lower in less isolated areas for non-First Nations (7.4, 6.0, 5.6, and 4.6 per 1,000, respectively). Adjusted odds ratios showed similar patterns. Living in less isolated areas was associated with lower infant mortality only among non-First Nations. First Nations infants do not seem to have similarly benefited from the better health care facilities in urban centers, suggesting a need to improve urban First Nations' infant care in meeting the challenges of increasing urban migration.The Journal of Rural Health 03/2010; 26(2):175-81. · 1.43 Impact Factor -
Article: Cesarean and vaginal birth in canadian women: a comparison of experiences.
[show abstract] [hide abstract]
ABSTRACT: Many publications have examined the reasons behind the rising cesarean delivery rate around the world. Women's responses to the Maternity Experiences Survey of the Canadian Perinatal Surveillance System were examined to explore correlates of having a cesarean section on other experiences surrounding labor, birth, mother-infant contact, and breastfeeding. A randomly selected sample of 8,244 estimated eligible women stratified primarily by province and territory was drawn from the May 2006 Canadian Census. Completed responses were obtained from 6,421 women (78%). Three-quarters of the women (73.7%) gave birth vaginally and 26.3 percent by cesarean section, including 13.5 percent with a planned cesarean and 12.8 percent with an unplanned cesarean. In addition to more interventions in labor, women who had a cesarean birth after attempting a vaginal birth had less mother-infant contact after birth and less optimal breastfeeding practices. Findings from the Maternity Experiences Survey indicated that women who have cesarean births experience more interventions during labor and birth and have less optimal birthing and early parenting outcomes.Birth 03/2010; 37(1):44-9. · 2.18 Impact Factor -

Article: Community Remoteness, Perinatal Outcomes and Infant Mortality among First Nations in Quebec.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: Little is known about community remoteness in relation to birth outcomes among Indigenous populations. We assessed whether community remoteness matters for perinatal outcomes and infant mortality in Quebec First Nations communities. STUDY DESIGN: A retrospective cohort study of all births (n=11,033) to residents of First Nations communities in Quebec 1991-2000, using linked vital statistics data. First Nations communities were grouped by community remoteness into four zones from the least to most remote. RESULTS: Preterm birth rates declined progressively from the least remote (8.0%) to the most remote (5.7%) zones (p=0.002). In contrast, total fetal and infant mortality rose progressively from the least remote (10.4 per 1000) to the most remote (22.7 per 1000) zones (p<0.001). The excess infant mortality in the more remote zones was mainly due to higher rates of postneonatal mortality. Similar patterns were observed after adjusting for maternal age, education, parity and marital status. Substantially elevated risks in most remote communities remained for perinatal death (adjusted OR=2.1), postneonatal death (adjusted OR=2.7), and total fetal and infant death (adjusted OR=2.3). CONCLUSION: Living in more remote First Nations communities was associated with a substantially higher risk of fetal and infant death, especially postneonatal death, despite a lower risk of preterm delivery. There is a need for more effective perinatal and infant care programs in more remote First Nations communities to reduce perinatal and infant mortality.The Open Women s Health Journal 01/2010; 4(1):32-38. -
Article: Individual- and Community-Level Disparities in Birth Outcomes and Infant Mortality among First Nations, Inuit and Other Populations in Quebec.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: We assessed individual- and community-level disparities and trends in birth outcomes and infant mortality among First Nations (North American Indians) and Inuit versus other populations in Quebec, Canada. METHODS: A retrospective birth cohort study of all births to Quebec residents, 1991-2000. At the individual level, we examined outcomes comparing births to First Nations and Inuit versus other mother tongue women. At the community level, we compared outcomes among First Nations and Inuit communities versus other communities. RESULTS: First Nations and Inuit births were much less likely to be small-for-gestational-age but much more likely to be large-for-gestational-age compared to other births at the individual or community level, especially for First Nations. At both levels, Inuit births were 1.5 times as likely to be preterm. At the individual level, total fetal and infant mortality rates were 2 times as high for First Nations, and 3 times as high for Inuit. Infant mortality rates were 2 times as high for First Nations, and 4 times as high for Inuit. There were no reductions in these disparities between 1991-1995 and 1996-2000. Modestly smaller disparities in total fetal and infant mortality were observed for First Nations at the community level (risk ratio=1.6), but for Inuit there were similar disparities at both levels. These disparities remained substantial after adjusting for maternal characteristics. CONCLUSION: There were large and persistent disparities in fetal and infant mortality among First Nations and Inuit versus other populations in Quebec based on individual- or community-level assessments, indicating a need to improve socioeconomic conditions as well as perinatal and infant care for Aboriginal peoples.The Open Women s Health Journal 01/2010; 4:18-24. -
Article: North-South Gradients in Adverse Birth Outcomes for First Nations and Others in Manitoba, Canada.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: to determine the relationship of north-south place of residence to adverse birth outcomes among First Nations and non-First Nations in Manitoba, Canada, a setting with universal health insurance. STUDY DESIGN: Live birth records (n=151,472) for the province of Manitoba, Canada 1991-2000 were analyzed, including 25,743 First Nations and 125,729 non-First Nations infants. North-south and rural-urban residence was determined for each birth through geocoding. RESULTS: Comparing First Nations to non-First Nations, crude rates in North (and South) were: 7.0% versus 8.4% (9.3% versus 7.5%) for preterm birth; 6.1% versus 8.4% (8.7% versus 10.0%) for small-for-gestational-age birth, 4.2% versus 6.5% (6.2% versus 5.7%) for low birth weight, and 20.6% versus 13.7% (17.0% versus 11.0%) for large-for-gestational-age birth; and mortality per 1000 - neonatal 3.2 versus 6.2 (3.8 versus 3.3), post-neonatal 6.4 versus 6.4 (5.8 versus 1.5), and infant 9.5 versus 12.6 (9.6 versus 4.8). Adjusting for observed maternal and infant characteristics and rural versus urban residence, the North was high risk for large-for-gestational-age birth for both First Nations and non-First Nations. First Nations' risk of preterm, small-for-gestational-age and low birth weight was lowest in the North, but for non-First Nations, the North was lower only for small-for-gestational-age. First Nations mortality indicators were similar North to South, but for non-First Nations, the North was high risk. CONCLUSION: North-South place of residence does matter for adverse birth outcomes, but the effects may differ by ethnicity and could require different intervention strategies.The Open Women s Health Journal 01/2010; 4:46-54.
