Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 6
Abstract
Background: Maternal weight gain during pregnancy is major determinant of birth weight, primary indicator of infant morbidity and mortality and exerts direct influence on pregnancy outcome. Appropriate weight gain advice is therefore of great importance. Present study was done to assess the maternal weight gain and its association with factors like birth weight of baby, maternal age, socio-economic status and gestational age in the study population. Methods: It is a hospital based prospective study. Study duration was from 14-10-1993 to 30-10-1994. Target population was women booked at 12 weeks of gestational period and who delivered at hospital during study period. Details regarding age, income, occupation, education, obstetrical history, menstrual history was collected from study subjects. After the delivery, the newborn baby was weighed, within 30 minutes of the birth, without clothing, on a lever type of weighing machine and weight was recorded in grams. All the above data were recorded and appropriate statistical tests were performed. Mean birth weight was analyzed in relation with the maternal weight gain. Multiple linear regression analysis was done to analyze relation of maternal age, socio-economic status and gestational age with maternal weight gain. Results: A cohort of 500 pregnant women was included in present study. Mean birth weight increased with the increase in maternal weight gain. The overall mean birth weight was 2728.9 grams. There was a difference of 335.1 grams in the birth weight at the two extremes of maternal weight gain. Maximum number of women i.e. 220 (44%) had weight gain of 5-7 Kg. (Mean Birth Weight 2628.9 grams), 145 (29%) had weight gain of 8-9 kg. (Mean birth weight 2704.8 grams). Multiple linear regression analysis showed that maternal age, socio-economic status and gestational age showed significant association with maternal weight gain. Conclusion: Pregnant women should receive appropriate weight gain advice, according to individual maternal characteristics. Better understanding of the influence of various maternal factors on weight gain values may strengthen the credibility and perhaps the influence of dietary advice to pregnant women.
