Link between saturated fat intake and heart rate variability in women with polycystic ovary syndrome


Dr Anita Kant    18 November 2017

A study published in the journal of Annals of Nutrition and Metabolism revealed that lower saturated fatty acid intake is associated with improved cardiovascular autonomic function in polycystic ovary syndrome PCOS . The researchers conducted this study with an aim of evaluating heart rate variability in women with PCOS n 84 and control n 54 based on the dietary intake of saturated fatty acid. The results demonstrated that body mass index blood pressure and HOMA IR were higher in women with PCOS. Moreover those with PCOS had higher testosterone dehydroepiandrosterone sulfate and free androgen index and lower sex hormone binding globulin levels than controls. The clinical profile and calorie intake were similar between saturated fatty acid categories in both the groups. In PCOS group testosterone level was lower when saturated fatty acid intake was less than 8.5 . PCOS women with SFA less than 8.5 consumed more beans fruits and vegetables. In addition they had better frequency and time domain heart rate variability indices. On the other hand in controls no differences in heart rate variability were identified between saturated fatty acid categories. In PCOS group age and saturated fatty acid intake were found to be the independent predictors of heart rate variability.
