Irregular periods can reduce life expectancy

Women with irregular or prolonged menstrual cycles have a higher risk of dying before the age of 70 from cardiovascular disease and cancer.

The research results were published in the journal BMJ on September 30.

Analysis conducted by US scientists from 1993 to present, with more than 79,500 women, average age of 37.7 participating. They all have not reached menopause, have no history of heart disease, cancer, or diabetes.

The participants must answer questions about their lifestyle and medical history twice a year. In addition, the degree of stability, or instability of the menstrual cycle in the three periods 14-17 years, 18-22 years, and 29-46 years old, has also been reported.

Medical history, death certificate after 24 years, showed that 1,975 people died before the age of 70, of which 849 died of cancer, 172 of heart disease.

The team concluded that, compared to women with stable menstrual cycles (26-31 days), those with irregular periods were at risk of dying before age 70 or dying young.

According to the research team, irregular periods are associated with a high body mass index (BMI), high blood pressure, high cholesterol, endometriosis, or a family history of diabetes.

Therefore, the menstrual group has a high risk of dying from cancer, especially cardiovascular diseases. The authors also added hormonal disturbances as one of the causes.

“There is a lot of scientific literature on the relationship between menstrual cycle problems and chronic diseases, but the impact on longevity is not clear,” said Dr. Jorge E. Chavarro, associate professor at the Department of Nutrition and Epidemiology at the Harvard School of Public Health, said study co-author.

He expressed hope that the research helps to raise awareness among health care providers that the menstrual cycle is “an important marker” to evaluate women’s health.

Dr. Frans M. Helmerhorst, from the Department of Clinical Epidemiology at the Leiden University Medical Center, said the study reinforces previous analyzes of the association between women not ovulating and heart disease. pulse, obesity.

Some experts acknowledge the results, but think that the research is still limited, especially when some volunteers used to be nurses, often work the night shift, the circadian clock is interrupted, affecting cycle.
