Maternal Preconception Body Mass Index and Gestational Weight Gain: A Prospective Cohort Study Potentially to Prevent Low Birth Weight

Pregnancy is the most critical period of growth and development change. Low and high birth weight infant would be having in the future the risk of many health problems. Adequate gestational weight gain (GWG) based on preconception body mass index (BMI) is important for optimal birth weight infants. This study aimed to 1) assess the relationship between preconception BMI and totalGWG; 2) calculate proportion of mother who does not meet weight gain recommendation. The longitudinal prospective study conducted from February 2013 to June 2014. The total 37 preconception women enrolled as samples and only 18 samples can be measured for GWG in 3rd trimester. Exclusion criteria were: 1) no data weighing for more than 3 months, 2) no records of first day of last menstrual period (LMP), and 3) miscarriage. Data of GWG compared to weight gain recommendations based on preconception BMI issued by Institute of Medicine. Collected data were analyzed by using STATA v.11. T-test was used to analyze the mean differences of BMI among groups then regression analysis was operated to assess the RR of GWG and nutritional status. We found no significant associations between preconception BMI and GWG (p>0.05). Based on maternal nutritional status at preconception, the highest risk not reaching GWG recommendation were in underweight women in 3rd trimester (RR=1, 43 [95%CI: 1, 00-2, 06]) (p<0.05). The lower nutritional status the higher total GWG even most of maternal did not meet IOM recommendation. Therefore, underweight maternal be required to be treated properly to avoid adverse pregnant outcomes.
