The association between fertility diet score and polycystic ovary syndrome: A Case-Control study

We performed this case-control study with 303 polycystic ovarian syndrome (PCOS) patients and 588 age-matched controls to evaluate the relation between fertility diet score and odds of PCOS. In a fully adjusted model, the top tertile of fertility diet score compared to the bottom was associated with 22% [95%CI 0.71-0.93] lower odds of PCOS (P trend = 0.012). Ratio of monounsaturated to trans fat and vegetable protein was associated with a lower odd of PCOS. Animal protein intake and glycemic load were associated with a higher odd of PCOS. Based on our results, increasing the quality of the diet according to fertility diet score can reduce the odds of PCOS.

Automated summary

This case-control study found that increasing the quality of the diet according to fertility diet score can reduce the odds of PCOS. The ratio of monounsaturated to trans fat and vegetable protein were associated with lower odds of PCOS, while animal protein intake and glycemic load were associated with higher odds of PCOS.
