Questions related to Nutritional Status
In checking for child malnutrition in a household, if there is more than one child, some are malnourished while others are not and we want to check the resilience capacity of the household, how do we classify the household, malnourished or not? and this is to check transition from one state to another between years.
I have researched the relationship between food consumption patterns and nutritional status. The result showed that significant relationship between iron intake with nutritional status (BMI). What causes iron intake to be related to nutritional status (BMI)? What is the mechanism? Are there other influencing factors that cause a relationship between iron intake with nutritional status?
I'm searching For a standard or any others questionnaire for Assessing nutritional status of GDM
I have data from households, where two types of data were collected:
- A validated questionnaire (Household Dietary Diversity Score (HDDS)), which gives a score between 0 and 12 for each household.
- Anthropometric measurements of all children < 5 years old in each household = a measure of nutritional status for the children.
I now wish to perform a regression analysis with HDDS score as independent variable and the anthropometric measurements as dependent variable.
The challenge is: In some households there were more than one child, which results in more observations of nutritional status than households scores, and the observations for the nutritional status are not independent, as some of the children come from the same household.
One way to g about it, is to take a mean of the nutritional status for all children in one household, but I would rather not do this, as children of different ages are difficult to compare regarding nutrition.
So what do I do to make sure I respect the assumption of independent observation in this analysis?
In case it's just not possible to perform a regression on this data, please feel free to suggest another analysis!
Hope there's someone out there who can help.
Please suggest standard questionnaire or format for interview schedule that can be used for conducting clinical assessment of deficiency signs and symptoms in relation to assessment of nutritional status in a rural community.
In the literature we can find research on the relationships: (1) emotional state and disease; (2) nutrition and disease. Can the two factors be considered together?
For example, if a person watches TV while eating - could this be a reason to get sick in the future?
I am working on comparative analysis of food and nutrition ( 6-23 months) security in two different production systems (groups). For the first phase of analysis, food security part, I have taken 182 households from one group and 188 from another group and finally I have conducted data analysis on household food security status. When I come to the second phase of the analysis, i.e. nutritional status of children between 6-23 months, I have found that the number of households who have children between 6 to 23 moths were only 54 in one group( which means 54 out of 188 households) and 172 in another group( which means 172 out 182 households) . So my question here is that , can I proceed with these sample sizes to make comparison between these groups?
N.B 1. I have already collected data
2. I am using ordinal logit( nutritional status and food security status) and Binary logit for some of nutritional status outcomes such as wasting , stunting and underweight.
I want to know, is there any association between fish consumption and nutritional status of adolescents; and its related review of literature if any.
Child growth is internationally recognized as an important indicator of nutritional status in populations and underweight, wasting, and stunting are the three most common indicators used to measure nutritional imbalance resulting in undernutrition. The percentage stunting in an area reflects the cumulative effects of undernutrition and infections since and even before birth. The percentage of underweight can reflect the percentage of ‘wasting’ indicating acute weight loss, ‘stunting’, or both. Thus, 'underweight' is a composite indicator and may therefore be difficult to interpret. But, scholars argue that wasting is not a preferable indicator of undernutrition in areas with a high prevalence of stunting, because it may underestimate undernutrition. Can this proposition be acceptable?
Can anyone have the information regarding the average nutritional status of this cocopeat and vermicompost? I want to know whether the cocopeat has the capacity to stand alone for a crop?
I am comparing multiple questionnaires for assessing nutritional status. The comparison is based on ROC analysis and I'm using SPSS.
A questionnaire used for the reference standard has 3 result categories, while other questionnaires are based on point scales without defined categories. So, cut off points are needed.
Till now in my work I was always defining only one cut off point for a specific method, so my question is:
What is the difference in defining, in this case, two cut off points instead of one, is it even possible and if it is, how to define them by using ROC analysis?
Thank you in advance.

I am currently undertaking a research pertaining the assessment of nutritional status of school age children 6-11 years, so I need help with more articles..
the elderly people are often identified as a vulnerable group who appear susceptible to malnutrition and disease. At the moment there are no standards for assessing the nutritional status of the elderly. In adults, body size and nutritional status are calculated using Body Mass Index (BMI is weight divided by height squared). The problem with doing the same for the elderly is that it can be difficult to measure their height because of spinal curvature or osteoporosis...
I am working on comparative analysis of household food security and nutritional status of coffee growers and what producer households of Ethiopia. Recently, Food and nutrition security is considered as single entity, rather than treating them as separate subjects. However, I couldn't find clear and sufficient sources to refer and work with. Most of researches indicated the title as " food and nutrition security" and yet their analyses came up with " food security" and " nutrition security " separately rather than "food and nutrition security" as combined analyses. I would appreciate if, anyone can help me to in this regard?

One of our students is interested to do research on effect of physical exercise on nutritional status and academic performance of sport sciences students. His subjects are university students studying for BSc in Sports sciences. He wanted to follow the students for two semesters. The aim is to see if the dietary intake of the students is inline with their physical activities and academic results... He proposed longitudinal study design but not sure how to calculate sample size. Please advise. Sincerely

I need a self-administered, validated questionnairre for assessing physical activity for children below 15 years of age to look for its relation to nutritional status. The available IPAQ questionnaire is for those above 15 years old and the Canadian Community Health Survey doesn't mention the details of the questionnairre
India has got its freedom in the year 1947 and we have already passed 68 year. Children are country's future human resources. Their health & nutrition should be in good condition. But recent survey revealed that the state-wide (West Bengal) prevalence of malnutrition was 26.1% & 19.6% in primary & upper-primary students respectively. Another 28.6% & 26.1% of the studied population were `At High Risk’ of developing under-nutrition (3rd to <10th percentile weight & height in respect to age & sex of Indian Academy of Paediatric standard) among primary & upper-primary students. State-wide Ideal Nutritional status was 17% & 23.5% among primary & upper-primary students. Prevalence of anaemia was 29% & 19% among primary & upper-primary students. Other important observations indicated that malnutrition was higher in rural students than their urban counterpart and more in boys than girls. But prevalence of anaemia was higher among girls than boys. Problem of exclusive stunting was 6.9% & 5.7% and that of exclusive under-weight was 6.4% & 4.6% among primary and upper-primary students respectively. Both under-weight and stunting was present in the tune of 12.8% & 9.3% in primary & upper-primary students respectively.
My question is how to improve this situation further as all studied subjects have been receiving receiving school meal programme (freshly prepared cooked meal that is served hot during lunch time)? Does nutrition surveillance at school level will improve the scenario apart from strengthening school meal services including its health components?
Is it possible to estimate the level of food security using nutritional status of children. if it so, how to estimate the same.
Please share some information.
I would like to draw the vector graphic according to the metodology descrited by Haase and Rose, 1995 (Vector analysis and its use for interpreting plant nutrient shifts...). Thanks.
Based on your experience, what do you think are the most reliable indicators of nutritional status in birds?
I would like to measure them in both adults and nestlings of seabirds.
Many thanks and best regards
I am looking for literature on nutritional status of adult specially focusing on daily laborers. I want to use these literature discussion part of my current study done on nutritional status of daily laborers. I was trying to look on google scholar and pubmed but I am not satisfied with search results. Any recommendation?
The phenol concentration is too high for the modified Lowry assay (for proteins) to be reliable. I've found that in most methods phenol in some way interferes in one of the reactions and selectively removing the phenol (or the proteins) seems like a tricky task as well.
Hi, I am confused with the assumption of linearity to the logit for continuous predictor variables in logistic regression analysis. Do we need to check for the linear relationship while screening for potential predictors using univariable logistic regression analysis?
In my case, I am using the multiple logistic regression analysis to identify factors associated with nutritional status (dichotomous outcome) among the participants. The continuous variables including age, Charlson comorbidity score, Barthel Index score, hand grip strength, GDS score, BMI etc. My first step is to screen for significant variables using simple logistic regression. Do I need to check for the linearity assumption during simple logistic regression analyses for each continuous variables? Or should I just check for it in the final multiple logistic regression model?
Besides, from my understanding, we need to log transform the non-linear continuous variable before enter it into the model. Can I categorize the non-linear continuous variable instead of transformation?
Nutrition is a indicator of poverty as it comes under the dimension of poverty i.e 'health'. How nutritional status of a particular community or a particular respondent can be calculated? What will be the criteria or on what basis we will do survey.
I have studied two populations of school boys (8-16 yrs age). The indices of malnutrition were calculated according to the classification of World Health Organization (WHO, 1995). Results shows that Population 2 has lower stunting values, but higher thinness and overweight values in comparison to population 1.
So, Which population has better nutritional status?
Can anybody answer the cause of this type of prevalence .
Is there any similar publication?
Human beings have adapted well through maintaining dietary habits in mountainous areas but it is also fact that people in such areas especially children have low nutritional status in compare to lowland areas. The changing dietary habits in mountainous areas have either degraded or bettered the nutritional status of these people. The growing food insecurity in such fragile environments is a global concern today. Anybody working is this line may kindly share information.
Organic fertilization: source of macro and micronutrients considered essential for plants and also other nutrients and organic substances.
To estimate the nutritional condition of fish and invertebrate larvae, biochemical methods are widely used. One of the most important is the RNA/DNA ratio. Since the quantity of DNA remains constant in the cells regardless the condition of the individual, but RNA levels are associated to metabolic activity, this ratio provides an accurate indication of the nutritional status of the individual.
Samples collected for this purpose are generally frozen or kept in RNAlater, which avoids any RNAse activity. However, often samples are collected with other purposes and kept, for example, in ethanol. Would it be feasible to use these samples for this type of analysis?
In this study, the results showed an association between nutritional status with intelligence by using the correlation test. But it was not clearly stated in the abstract if the nutritional statuses, which were used in the analysis of correlation with intelligence, were by height for age or weight for age.
Eclamsia is a major cause of maternal mortality, morbidity and adverse fetal and neonatal outcome. There are research attempts to investigate the factors associated with eclamsia; but is there any recent finding that suggests the association of eclamsia with specific nutrient deficiency in developing countries.
I am working on some topics related to nutritional status in children and poverty, but I cannot understand the ideas of " stunting, overweight" etc. Would anybody like to explain and provide the standard formulas to calculate them?
Diet diaries and food frequency questionnaires are time consuming.
What alternative methods exist as alternative to 24 hours recall and diet diaries to assess the dietary patterns in epidemiological studies?
