The effects of dietary approaches to stop hypertension diet on weight loss, anti-Müllerian hormone and metabolic profiles in women with polycystic ovary syndrome: A randomized clinical trial

Clin Endocrinol (Oxf). 2017 Jul;87(1):51-58. doi: 10.1111/cen.13333. Epub 2017 Apr 11.


Objective: This study was designed to evaluate the effects of the dietary approaches to stop hypertension (DASH diet) on weight loss, anti-Müllerian hormone (AMH) and metabolic profiles in women with polycystic ovary syndrome (PCOS).

Design, patients and measurements: A randomized controlled clinical trial was conducted among 60 overweight or obese patients with PCOS. Patients were randomly assigned to receive either low-calorie DASH (N=30) or control diet (N=30) for 12 weeks. The DASH and control diets were consisted of 52%-55% carbohydrates, 16%-18% proteins and 30% total fats; however, the DASH diet was designed to be rich in fruits, vegetables, whole grains, low-fat dairy products, cholesterol and refined grains. Both diets were equicaloric.

Results: Adherence to the DASH diet, compared to the control diet, resulted in a significant decrease in BMI (-1.6±0.5 vs -1.2±0.7 kg/m2 , P=.02). Significant decreases in AMH (-1.1±3.1 vs +0.3±0.7 ng/mL, P=.01), insulin (-25.2±51.0 vs -1.2±28.8 pmol/L, P=.02), homoeostasis model of assessment-estimated insulin resistance (-0.9±2.0 vs -0.1±1.0, P=.02), free androgen index (FAI; -0.03±0.09 vs +0.06±0.21, P=.02) and malondialdehyde (MDA) levels (-0.5±0.4 vs +0.2±0.3 μmol/L, P<.001), and significant increases in quantitative insulin sensitivity check index (+0.01±0.03 vs -0.004±0.01, P=.02), sex hormone-binding globulin (SHBG; +3.7±8.5 vs -1.5±7.2 nmol/L, P=.01) and nitric oxide (NO; +9.0±4.9 vs +0.6±2.3 μmol/L, P<.001) were also seen in the DASH group compared with the control group.

Conclusions: Adherence to the DASH diet for 12 weeks among PCOS women had beneficial effects on BMI, AMH, insulin metabolism, SHBG, FAI, NO and MDA levels.
