title: Anthropometric and body composition characteristics during pregnancy: a study from West Bengal, India.
abstract: The present cross-sectional study was aimed at investigating changes in anthropometric, body composition and blood pressure characteristics during pregnancy. A total of 406 healthy, pregnant women aged between 16 and 33 years participated in the study. Pregnant women were recruited from the outpatient department of the two-referral hospital in Bolpur subdivision of Birbhum district, West Bengal, India. Anthropometric measures such as height, weight, three circumferences and skinfold thickness at four sites (biceps, triceps, subscapular and suprailaic) were obtained using standard techniques. Percentages of body fat (%BF), intra abdominal visceral fat (IVF), basal metabolic rate (BMR) and body mass index (BMI) were measured using an Omron body fat analyser. Two forenoon blood pressure measurements were also taken and averaged for analysis. Subjects were categorized into three trimester groups: Group I, n=30; Group II, n=163; and Group III, n=213. ANOVA with Scheffe's post-hoc test revealed that Group I had significantly lower mean than both Group II and Group III for systolic blood pressure and IVF, whereas Group I had significantly lower mean than Group III for BMI, BMR, %BF, diastolic blood pressure and skinfolds. The mean change in maternal weight from the first to the third trimester was merely 3 kg. Mean waist circumference varied from the first to the third trimester but not from the first to the second trimester. Furthermore, significantly increased systolic and diastolic blood pressure was observed across the trimesters. However, longitudinal studies involving interaction of body fat topography and pregnancy-induced hormones are required to further our understanding of gestation mechanism.
