Research reports on obesity from University of California provide new insights
2009 JUL 13 - (NewsRx.com) -- According to recent research published in the American Journal of Obstetrics and Gynecology, "The objective of the study was to examine risk factors for postterm (gestational age >= 42 weeks) or prolonged (gestational age >= 41 weeks) pregnancy. We conducted a retrospective cohort study of all term, singleton pregnancies delivered at a mature, managed care organization." "The primary outcome measures were the rates of pregnancies greater than 41 or 42 weeks' gestation. Multivariable logistic regression models were used to control for potential confounding and interaction. Specific risk factors for pregnancy beyond 41 weeks of gestation include obesity (adjusted odds ratio [aOR], 1.26; 95% confidence interval [CI], 1.16-1.37), nulliparity (aOR, 1.46; 95% CI 1.42-1.51), and maternal age 30-39 years (aOR, 1.06; 95% CI, 1.02-1.10) and 40 years or older ( aOR, 1.07; 95% CI, 1.02-1.12). Additionally, African American, Latina, and Asian race/ethnicity were all associated with a lower risk of reaching 41 or 42 weeks of gestation. Our findings suggest that there may be biological differences that underlie the risk for women to progress to 41 or 42 weeks of gestation," wrote A.B. Caughey and colleagues, University of California. The researchers concluded: "In particular, obesity is a modifiable risk factor and could potentially be prevented with prepregnancy or interpregnancy interventions." Caughey and colleagues published their study in American Journal of Obstetrics and Gynecology (Who is at risk for prolonged and postterm pregnancy' American Journal of Obstetrics and Gynecology, 2009;200(6):E1).
