Association Of Maternal Bmi And Anthropometry Of New-Born- A Hospital Based Cross Sectional Study

Abstract

Background and Objective: Birth weight of the new-born is the single most predictor of its survival. As per world Health Organization, low birth weight is defined as birth weight less than 2500 g. The definition of Low Birth Weight does not take into account the gestational period. The reason for LBW could be prematurity or intra uterine growth restriction. In developing countries Intrauterine growth restriction constitutes major proportion of LBW. Maternal nutrition during pregnancy has been regarded as an important determinant for foetal growth, hence the study was conducted to know the association of maternal body mass index on anthropometry of New-born Methodology: Study population: Registered pregnant women delivering at KLE’s Prabhakar Kore Charitable Hospital. Study design: A hospital based cross sectional study. Study period: One year (1st January to 31st December 2017). Data was collected using pre-designed and pre-tested questionnaire. Results: Mean maternal age of the study participants was 24.28 ± 3.34 years and mean parity was 1.68 ± 0.73. Mean Maternal Height was 155.25 ± 7.08 cm. The mean maternal weight at the third trimester was 52.95 ± 9.86 and the mean maternal BMI was 21.98± 4.3. Mean birth weight of the new-born was 2.83 ± 0.4 kg. Prevalence of low birth weight was 17.42%.Study showed significant association between maternal BMI at all trimester and birth weight of the new-born. 1st and 2nd trimester BMI showed positive association with length of the new-born. Maternal BMI at 2nd and 3rd trimester also showed positive association with head circumference of the new-born. The maternal BMI at 1st, 2nd and 3rd trimester didn’t show positive association with chest circumference of the new-born. Conclusion: Positive association was seen between maternal BMI at all trimester and weight of the new-born. Interventions targeted during pregnancy to improve the nutritional status of the mother helps to improve the birth weight of the new-born.
