Dietary Intake in Third Trimester of Pregnancy and Prevalence of LBW: A Community-based Study in a Rural Area of Haryana.

Objectives: (1) To assess the magnitude of the problem of low birth weight (LBW) in a rural area of Haryana (2) To study the association of caloric and protein intake in third trimester of pregnancy with birth weight. Study Design: Longitudinal study. Sample Size: One hundred and forty pregnant women. Study Area: Ten purposively selected villages in the rural area of Naraingarh block in Haryana. Study Tool and Data Collection: Pre-tested questionnaire was administered to record information regarding socioeconomic status, antenatal care, nature of physical activity and dietary intake in 24 h between September 2001 and August 2002. Data Analysis: For categorical variables, Chi-square test was used, and for numerical variables, t-test was used. Multivariate analysis was done for variables that were significant in bivariate analysis. Results: The prevalence of low birth weight (less than 2500 g) was 24.3% (95% CI 17.4-32.2%). The mean caloric intake during three dietary assessments was 1695 ± 182.8 kcal. The mean protein intake during three dietary assessments was 50.8 ± 9.27 g. The higher prevalence of LBW babies was observed in pregnant women with mean caloric intake of less than 1500 kcal and mean protein intake of less than 40 g (P < 0.001). In multivariate analysis, the association of caloric intake (P < 0.01) and weight of the mother (P = 0.02) was independently associated with LBW. Conclusions: Low caloric intake in the third trimester of pregnancy and maternal weight are significantly associated with the birth weight of babies. [ABSTRACT FROM AUTHOR]
