Abstract BACKGROUND AND OBJECTIVES: We examined the effect of body mass index in early pregnancy on pregnancy outcome since no study in Saudi Arabia has addressed this question. METHODS: This prospective cohort study involved women registered for antenatal care during the first month of pregnancy at primary health care centers in Al-Hassa, Saudi Arabia. Data was collected from records and by direct interview. RESULTS: The study included 787 women. Compared to normal weight women (n=307), overweight (n=187) and obese (n=226) women were at increased risk for pregnancy-induced hypertension (RR=4.9 [95\% CI 1.6-11.1] and 6.1 [95\% CI 2.1-17.8], respectively), gestational diabetes (RR=4.4 [95\% CI 1.2-16.3] and 8.6 [95\% CI 2.6-28.8]), preeclamptic toxemia (RR=3.8 [95\% CI 1.1-14.6] and 5.9 [95\% CI 1.7-20.4]), urinary tract infections (RR=1.4 [95\% CI 0.5-3.9] and 3.7 [95\% CI 1.7-6.2]), and cesarean delivery (RR=2.0 [95\% CI 1.3-3.0] in obese women). Neonates born to obese women had an increased risk for postdate pregnancy (RR=3.7 [95\% CI 1.2-11.6]), macrosomia (RR=6.8 [95\% CI 1.5-30.7]), low 1-minute Apgar score (RR=1.9 [95\% CI 1.1-3.6]), and admission to neonatal care units (RR=2.1 [95\% CI 1.2-2.7]). On the other hand, low birth weight was less frequent among obese women (RR=0.5 [95\% CI 0.3-0.9]) while the risk was high among underweight women (RR=2.3 [95\% CI 1.4-3.8]). CONCLUSION: Even with adequate prenatal care, overweight and obesity can adversely affect pregnancy outcomes.
