Association between dietary fat intake and risk of polycystic ovary syndrome
OBJECTIVE To analyze the association between dietary fat intake and the risk of polycystic ovarian syndrome(PCOS).METHODS PCOS patients treated in a tertiary hospital in Anhui Province from October 2021 to October 2022 were selected as the case group,and non-PCOS patients treated in the hospital during the same period were selected as the control group.A total of 262 subjects were included in the study,131 were included in the case group and 131 in the control group.A semi-quantitative dietary frequency questionnaire was used to investigate the dietary intake in the past year,and the daily intake of various fatty acids and the ratio of fatty acid energy supply were calculated according to the food intake.Logistic regression analysis was used to investigate the association between dietary fat intake and the risk of PCOS.RESULTS The dietary intakes of total fat,fatty acid,saturated fatty acid and monounsaturated fatty acid in PCOS patients were higher than those in control group(P＞0.05),and there was statistical significance in daily intakes of eicosapentaenoic acid between two groups(P＜0.05).After adjusting for confounding factors such as long-term residence,occupation,family per capita monthly income,menstrual cycle regularity,menstrual volume,and weight loss experience,Logistic regression analysis showed that the ratio of fat supply to energy was positively correlated with the risk of PCOS(OR=1.622,95％CI 1.237-2.127).The energy supply ratio of monosaturated fatty acids(OR=0.597,95％CI 0.373-0.955)and polyunsaturated fatty acids(OR=0.585,95％CI 0.372-0.921)were negatively correlated with the risk of PCOS(P＜0.05).CONCLUSION The energy supply ratio of fat was positively correlated with the risk of PCOS,while the energy supply ratio of monosaturated fatty acids and the energy supply ratio of polyunsaturated fatty acids were negatively correlated with the risk of PCOS.
