Study Question: Are physical activity (PA) and body mass index (BMI) associated with irregular periods and heavy menstrual bleeding (HMB) in Australian women?
Summary Answer: Overweight and obese women have higher odds of both irregular periods and HMB than underweight/normal-weight women, but high levels of PA reduce the odds of HMB.
What Is Known Already: Most studies on relationships between PA and menstrual problems have focused on female athletes, but there have been few population-based studies.
Study Design, Size, Duration: Prospective cohort study, 10618 participants in the Australian Longitudinal Study of Women's Health (ALSWH) who completed mailed surveys in 1996, with follow-ups in 2000, 2003, 2006, 2009, 2012, and 2015. Read More
