Nutritional Correlates of Women with a History of Gestational Diabetes and Insulin Resistance in the National Health and Nutrition Examination Survey (NHANES) 2000-2010
Objective: To evaluate the associations of gestational diabetes (GDM) history with dietary intake, nutritional status, insulin resistance, demographic, and anthropometrical data. Materials & Methods: This cross-sectional study used data from the National Health and Nutrition Examination Survey for the years 2000-2010. Data analysis was based on 290 women who reported a history of GDM compared to 4239 women who denied a GDM history. Insulin resistance [HOMA_IR = (fasting insulin in mU/mL × fasting glucose in mmol/L)/405] was calculated. Pearson correlation, Wilcoxon rank sum tests, Student’s t-tests, and chi-square analysis were used while linear regression assessed independent associations. Results: The median time-lapse from the diagnosis of GDM was 15 years. Women with a GDM history had significantly higher body mass index (BMI), other anthropometric measurements, diastolic blood pressures and insulin resistance. They were also more likely to be Hispanic, have delivered macrosomic infants, and delivered via cesarean. Previous GDM history compared to non-GDM subjects had significantly higher dietary intakes of energy calories, protein, total fat, saturated fatty acids, mono-saturated fatty acids, and cholesterol. Within the entire cohort, increasing insulin resistance was also associated with lower income, less college education, Hispanic or African American ethnicity, obesity, higher systolic and diastolic blood pressures, and with higher dietary cholesterol but lower intake of dietary fiber and micronutrients. Regression analyses showed that GDM history, Hispanic ethnicity, BMI, dietary intake of cholesterol and decreasing income were independently predictive of insulin resistance. Conclusion: The data confirm that even many years after a pregnancy associated with GDM, women with a history of GDM still report significantly higher dietary intakes of energy calories, protein, and fat with no corresponding increase in consumption of dietary fiber or minerals and vitamins. Consequently, the increased calorie and food consumption of women with previous GDM are associated with obesity, insulin resistance and higher blood pressures. These observations may suggest the need to target high-risk groups who may need more resources and awareness of the benefits of quality nutrition.
