Gestational nutrition improves outcomes of vaginal deliveries in Jordan: an epidemiologic screening.

Adequate and balanced nutrition during gestation is essential for achieving healthy pregnancy outcomes. This retrospective survey tested the hypothesis that maternal nutrition (macronutrients intake, micronutrients intake, and weight gain) during gestation will impact gestational outcomes (gestational age, birth weight, and labor spontaneity). The objectives of this study were to test the impact of macronutrients and micronutrients consumed during gestation, pregestational weight and weight gain during gestation on gestational age, birth weight, and labor spontaneity among Jordanian women. Study participants (n = 700) were recruited from a women's hospital in northern Jordan. Data were collected using structured interviews. Dietary determinants examined in the study included daily intake of macronutrients (energy, carbohydrate, protein, fat, and n-3 and n-6 fatty acids) and micronutrients (zinc, calcium, folate, vitamin C, vitamin A, and vitamin B6), pregestational body mass index, total weight gain, and weight gain pattern during pregnancy. Dietary data were obtained from a semiquantitative food frequency questionnaire. Mean (SEM) daily intakes of energy, carbohydrate, and protein were 10894 (138) Kj, 320 (3.8) g, and 90 (0.95) g, respectively; with fat contributing 36% of total energy. Average daily energy and carbohydrate intake during pregnancy were related negatively to gestational age (P < .05). Pregestational body mass index was associated positively with gestational age and birth weight (P < .05). Intakes of vitamin A and calcium had significant relationships with birth weight. Daily intakes of zinc, calcium, vitamin B6, and n-3 and n-6 fatty acids were associated with labor spontaneity. Dietary factors consumed during pregnancy are associated with pregnancy outcomes.
