Is it possible to predict your longevity based on your current or previous menstrual cycle? A study published in The BMJ on Oct. 3, 2020, linked irregular or menstrual periods that are long (defined as 40 days or more) both in adolescence and adulthood to a higher risk of early death (before age 70) than those with normal or short menstrual cycles. The researchers discovered that the link was stronger for fatalities from heart and blood vessel disease and among women who smoked, based on data from roughly 80,000 women who took part in the Nurses' Health Study II.
When the trial began, the women in the study were on average 38 years old and had no history of cardiovascular disease, cancer, or diabetes. The women were asked to recall the regularity and length of their menstrual cycles at different points throughout their lives. The ladies were followed for 24 years, and fatalities for various reasons were recorded. Even after controlling for other factors including lifestyle and family history, the link between early death and irregular or extended menstrual cycles remained.
