A healthy diet after pregnancy may help reduce risk of high blood pressure in women who had gestational diabetes mellitus (GDM), according to a new report in
Researchers conducted the analysis based on data from 3818 women with a history of GDM who were part of the Nurses’ Health Study II and were followed up from 1989 to 2011. Self-administered questionnaires previously validated by medical record review were used to identify incident hypertension.
Scores for adherence for following the alternative Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH), and the alternative Healthy Eating index 2010 (AHEI) were computed for each woman. The associations between dietary scores and hypertension were evaluated using Cox proportional hazard models.
Over the course of 18.5 years of follow up, 1069 cases of incident hypertension were reported. After adjustment for major risk factors for hypertension, the alternative Mediterranean and DASH diets and the AEHI were significantly inversely associated with risk of hypertension: hazard ratios and 95% confidence interval comparing the extreme quartiles (highest vs lowest) 0.76 (0.61–0.94; P for linear trend =0.03) for AHEI score, 0.72 (0.58–0.90; P for trend =0.01) for Dietary Approach to Stop Hypertension score, and 0.70 (0.56–0.88; P for trend =0.002) for alternative Mediterranean diet score.
The researchers concluded that sticking to a healthful dietary pattern reduces the risk of developing hypertension among women who have a history of GDM.
