    "abstract": "In this study, we aimed to investigate the relationship between body mass index (BMI), waist circumference (WC) or waist-to-hip ratio (WHR) and oligomenorrhea or irregular menstruation in Chinese women of childbearing age.\nA total of 1,423 Han women aged 19-39\u2009years who were routinely examined at the Physical Examination Center of Peking University People's Hospital were enrolled by convenience sampling method. All participants were asked to fill up menstrual questionnaires. Binary logistic regression models were used to assess the odds ratio (OR) of different BMI, WC and WHR groups for the prevalence of oligomenorrhea and irregular menstruation. Moreover, we used the ROC curves to compare the predictive effects of BMI, WC and WHR on oligomenorrhea and irregular menstruation.\nAmong the 1,423 participants, 93 women (6.5%) had BMI \u2265 30\u2009kg/m\nObesity, oligomenorrhea and irregular menstruation were common in Chinese women of childbearing age, and obesity was associated with oligomenorrhea and irregular menstruation. Abdominal obesity might have a stronger predictive effect on irregular menstruation.",
