BACKGROUND Low birth weight (LBW) is an important public health problem in undernourished populations. OBJECTIVE We tested whether improving women's dietary micronutrient quality before conception and throughout pregnancy increases birth weight in a high-risk Indian population. DESIGN The study was a nonblinded, individually randomized controlled trial.(More)
RESEARCH QUESTION: Intakes of micronutrient-rich foods are low among women of child-bearing age living in slums. We investigated relationships between consumption of these foods and socio-demographic variables. METHODOLOGY: A 91-item Food Frequency Questionnaire was administered to women (n=1651) aged 16-40 yrs living in a Mumbai slum. We identified(More)
Background: Low birth weight (LBW) is an important public health problem in undernourished populations. Objective: We tested whether improving women's dietary micro-nutrient quality before conception and throughout pregnancy increases birth weight in a high-risk Indian population. Design: The study was a nonblinded, individually randomized controlled trial.(More)
BACKGROUND Prospective observational studies suggest that maternal diets rich in leafy green vegetables and fruit may help prevent gestational diabetes mellitus (GDM). OBJECTIVE Our objective was to test whether increasing women's dietary intake of leafy green vegetables, fruit, and milk before conception and throughout pregnancy reduced their risk of(More)
Intakes of micronutrient-rich foods are low among Indian women of reproductive age. We investigated whether consumption of a food-based micronutrient-rich snack increased markers of blood micronutrient concentrations when compared with a control snack. Non-pregnant women (n 222) aged 14-35 years living in a Mumbai slum were randomised to receive a treatment(More)
Heavy gas dispersion models have been developed at IIT (hereinafter referred as IIT heavy gas models I and II) with a view to estimate vulnerable zones due to accidental (both instantaneous and continuous, respectively) release of dense toxic material in the atmosphere. The results obtained from IIT heavy gas models have been compared with those obtained(More)
Improving micronutrient intakes of under-nourished mothers in low- and middle-income countries increases birth weight, but there is little data on the nature and timing during gestation of any effects on fetal growth. Ultrasound measures of fetal size were used to determine whether and when a food-based supplement affected fetal growth. Non-pregnant women(More)
Vitamin B12 is an important cofactor in one-carbon metabolism whose dysregulation is associated with various clinical conditions. Indians have a high prevalence of B12 deficiency but little is known about the genetic determinants of circulating B12 concentrations in Indians. We performed a genome-wide association study in 1001 healthy participants in the(More)
