Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2018, Vol 5, Issue 36
Abstract
BACKGROUND Nutrition plays an important role in a woman’s ability to sustain her pregnancy. Nearly 54% of Asian pregnant women were found to be at increased risk of inadequate energy intake. During pregnancy, a woman requires an extra 300-400 kcal/day, restriction of which leads to adverse maternal and foetal outcomes. Less is known about the impact of gestational weight gain in conjunction with BMI on perinatal outcomes in healthy pregnant women without other co-morbidities. The objectives of the study were to assess the prevalence of abnormal BMI in early pregnancy and to compare the two standards of BMI classification namely, the WHO classification for the general population and the revised classification for Asian Population. MATERIALS AND METHODS This study was a prospective descriptive study. The study was done during the months of August and September 2016 in a tertiary care hospital in South India. All pregnant women who registered in the hospital for antenatal care, prior to 12 weeks and 6 days were recruited. The profiles of the enrolled pregnant women were collected using a proforma and the values of BMI for each class from the WHO general classification system was compared to the corresponding class of the WHO classification system for the Asian population. The sample size needed for this study was estimated to be 384, assuming a prevalence of 50%, absolute precision of 5% and 95% confidence interval. RESULTS The participants’ age ranged from 18 to 44 years with a mean age of 26.0 ± 4.4 years. Of the pregnant mothers, 185 (46.3%) were multiparous and 215 (53.7%) were nulliparous. Out of the total of 400 pregnant mothers, 293 (73.3%) patients lived in an urban and 107 (26.7%) lived in rural areas. There were 176 (44%) graduates, 213 (53.3%) who had studied till atleast 5th standard and 11(2.7%) with no basic education. Thus among the participants, 97.3% had some form of basic education. CONCLUSION 1. Based on the WHO general standard of BMI classification, 201(50.2%) mothers were of ideal BMI, 57 (14.2%) were underweight, 95 (23.8%) were overweight and 47 (11.8%) were obese. 2. On comparing the two methods of WHO BMI classification (general and Asian), it was evident that the Asian classification classified more number of mothers to be in the higher risk category (137 (34.2%) were of ideal BMI, 123 (30.8%) were overweight and 83 (20.8%) were obese) 3. Of the 400 participants 199 (49.8%) had abnormal BMIs by general standards and 263 (65.8%) by the Asian standard.
