Impact of Second Trimester Maternal Dietary Intake on Gestational Weight Gain and Neonatal Birth Weight.

ABSTRACT: Poor maternal nutrition is a major contributor to the high incidence of low birth weight deliveries in developing countries. This study aimed to assess the impact of second trimester maternal dietary intake on gestational weight gain and neonatal birth weight. A longitudinal study was conducted in a tertiary care hospital in Sri Lanka. Participants were 141 pregnant women at 18-24 weeks gestation who were followed up until delivery. Maternal dietary intake was assessed using a validated Food Frequency Questionnaire at 21.1 ± 1.8 gestational weeks. Gestational weight gain was examined at the end of 28 weeks gestation and at the end of pregnancy. Energy and nutrient intakes were calculated using NutriSurvey 2007 (EBISpro, Willstaett, Germany) nutrient analysis software, modified for Sri Lankan foods. The mean total gestational weight gain of women with low carbohydrate intake (229-429 g/day) was 2.2 kg less than that of women with moderate carbohydrate intake (430-629 g/day) (95% confidence interval (CI) 0.428-4.083 kg; p = 0.016). Similarly, babies of women with low carbohydrate intake were 312 g lighter compared with those of women with a moderate carbohydrate intake (95% CI 91-534 g; p = 0.006). Our results suggest that second trimester maternal carbohydrate intake has significant impacts on total gestational weight gain and neonatal birth weight.

Project description:IntroductionTo date, there have only been provisional recommendations about the appropriate gestational weight gain in twin pregnancies. This study aimed to contribute evidence to this gap of knowledge.Material and methodsUsing a cohort of 10 603 twin pregnancies delivered between 2000 and 2015 in the state of Hessen, Germany, the individual and combined impact of maternal body mass index and gestational weight gain on maternal and neonatal outcomes was analyzed using uni- and multivariable logistic regression models. The analysis used newly defined population-based quartiles of gestational weight gain in women carrying twin pregnancies (Q1: <419.4 g/week [low weight gain], Q2-Q3: 419.4-692.3 g/week [optimal weight gain], Q4: >692.3 g/week [high weight gain]) and the World Health Organization body mass index classification.ResultsPre-pregnancy body mass index ≥25 kg/m2 was associated with significantly increased rates of cesarean deliveries (aOR1.2, 95% CI: 1.01-1.41) and pregnancy-induced hypertensive disorders (aOR 1.53, 95% CI: 1.11-2.1) but not with any adverse neonatal outcome. Perinatal mortality (aOR 2.23, 95% CI: 1.38-3.6), preterm birth (aOR 1.88, 95% CI: 1.58-2.25), APGAR'5 < 7 (aOR 1.61, 95% CI: 1.19-2.17) and admissions to the neonatal intensive care unit (aOR 1.6, CI: 1.38-1.85) were increased among women with low gestational weight gain. Rates of cesarean deliveries were high in both women with low (aOR 1.25, 95% CI: 1.05-1.48) and high gestational weight gain (aOR 1.17, 95% CI: 1.01-1.35). A high gestational weight gain was also associated with higher rates of hypertensive disorders in pregnancy (aOR 2.32, 95% CI: 1.79-3.02) and postpartum hemorrhage (aOR 1.72, 95%CI: 1.12-2.63). The risk of preterm birth, low Apgar scores and NICU admissions showed a converse linear relation with pre-pregnancy body mass index in women with low gestational weight gain.ConclusionsIn twin pregnancies, nonoptimal weekly maternal weight gain seems to be strongly associated with maternal and neonatal adverse outcomes. Since gestational weight gain is a modifiable risk factor, health care providers have the opportunity to counsel pregnant women with twins and target their care accordingly. Additional research to confirm the validity and generalizability of our findings in different populations is warranted.
