OBJECTIVE: To determine risk of delivering a preterm infant (<37 weeks) in overweight/obese women.
DESIGN: Descriptive.
SAMPLE: Population-based sample of 169,881 singleton Missouri birth certificate records for 1998-2000.
MEASURES: Prepregnancy body mass index (BMI): underweight BMI<19.8; normal BMI=19.8-24.9; overweight BMI=25-29.9; and obese BMI> or =30; and preterm birth (<37 completed weeks' gestation).
RESULTS: In each BMI category, the percent of women who delivered a preterm infant is: underweight 11.5%, normal 8.3%, overweight 8.2%, and obese 8.5%. For women with a BMI of overweight (odds ratio [OR] 0.9, 95% confidence interval [CI]=0.8-0.9) and obese (OR 0.8, 95% CI=0.8-0.9), the risk of delivering a preterm infant decreased when compared with women with a BMI<19.8. Black (OR=2.5, 95% CI 2.4-2.6) and Hispanic (OR=1.4, 95% CI 1.2-1.5) women had a higher risk of preterm birth than White women when obesity, diabetes, hypertension, and prenatal care were controlled. Women with diabetes (OR=1.4, 95% CI=1.2-1.5), hypertension (OR=3.2, 95% CI=3.1-3.4), and those who smoked (OR=1.6, 95% CI=1.6-1.7) were at increased risk for a preterm birth.
CONCLUSIONS: Findings suggest that preconception and prenatal care focus on identification and management of risks associated with premature births and maternal risk factors such as diabetes, hypertension, and smoking.
