OBJECTIVE -To estimate the prevalence of several health-related behaviors among women of reproductive age with and without a history of gestational diabetes mellitus (hGDM).RESEARCH DESIGN AND METHODS -We performed a cross-sectional study using the [2001][2002][2003] Behavioral Risk Factor Surveillance System, a national population-based random sample telephone survey. Participants were 177,420 women aged 18 -44 years with and without self-reported hGDM. Outcome measures included meeting physical activity and fruit and vegetable guidelines, sedentary activity level, and current smoking.RESULTS -Approximately 3% (n ϭ 4,718) of women aged 18 -44 years reported physiciandiagnosed hGDM. Women with hGDM had higher BMIs, were significantly older, were less often educated or employed, and were more often Hispanic or African American, married, and living with children. Women with hGDM reported worse self-rated health than women without hGDM. In unadjusted and multivariate adjusted comparisons, there were no significant differences in levels of physical activity, fruit and vegetable consumption, or smoking among women with and without hGDM. However, women with hGDM who lived with children were significantly less likely to meet fruit and vegetable consumption guidelines (odds ratio 0.78 [95% CI 0.63-0.97]; P Ͻ 0.05) and more likely to smoke (1.21 [1.01-1.47]; P Ͻ 0.05) than their counterparts without hGDM.CONCLUSIONS -Despite their elevated risk for future diabetes, women with hGDM who lived with children were less likely to meet fruit and vegetable consumption guidelines and more likely to smoke than women with children who did not have hGDM.
Diabetes Care 29:1788 -1793, 2006G estational diabetes mellitus (GDM), or glucose intolerance first recognized during pregnancy, affects 3-8% of pregnancies in the U.S. (1). The incidence of GDM is increasing, fueled by maternal obesity and advancing maternal age (2). Although most women with GDM return to normal glucose tolerance after delivery, as many as 10 -50% of women with GDM are diagnosed with type 2 diabetes within 5 years (3-5). Better characterization of women with a history of gestational diabetes mellitus (hGDM) has taken on heightened urgency after the Diabetes Prevention Program (DPP) found that its lifestyle intervention prevented or delayed the onset of type 2 diabetes (6). The DPP specifically recruited women with self-reported hGDM and current glucose intolerance, among other risk factors (7). The DPP lifestyle intervention successfully prevented or delayed the onset of type 2 diabetes among women with and without hGDM (R. Ratner, personal communication).To our knowledge, there have been no population-based studies of health behavior for U.S. women with hGDM. In the Nurses Health Study II, women who eventually developed GDM had poorer health behaviors than unaffected women before pregnancy (8). These behavioral patterns may have continued after pregnancy. In another prospective cohort study, women with hGDM had significantly poorer physical functioning before preg...
