Women's lifestyle changes, even in middle age, may reduce future stroke risk

Middle age may not be too late for women to substantially reduce their stroke risk by not smoking, exercising, maintaining a healthy weight and making healthy food choices, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
In general, women are more likely than men to have a stroke, die from stroke and have poorer health and physical function after a stroke. The average age of first stroke in women is 75 years. Based on this information, researchers theorized that making mid-life lifestyle changes might help reduce stroke's burden among women.
"We found that changing to a healthy lifestyle, even in your 50s, still has the potential to prevent strokes," said Goodarz Danaei, Sc.D., lead study author and Bernard Lown Associate Professor of Cardiovascular Health at Harvard T.H. Chan School of Public Health in Boston. "Women who made lifestyle modifications in middle age reduced their long-term risk of total stroke by nearly a quarter and ischemic stroke, the most common type of stroke, by more than one-third."
Researchers analyzed the Nurses' Health Study, which includes health information on nearly 60,000 women who enrolled at average age of 52 and continued in the study for an average of 26 years. Researchers studied the impact on stroke risk from smoking cessation, exercising 30 minutes or more daily and gradual weight loss if women were overweight. The researchers also studied the impact of making recommended dietary modifications that emphasize eating more fish, nuts, whole grains, fruits and vegetables and less red meat, no processed meat and less alcohol.
During the 26-year follow-up, researchers found:
4.7% of women with no lifestyle interventions had a stroke of any type; 2.4% had ischemic stroke; and 0.7% had hemorrhagic stroke.
Engaging in the three non-dietary interventions -- smoking cessation, daily exercise and weight loss -- was estimated to reduce the risk of total stroke by 25% and ischemic stroke by 36%.
Sustained dietary modifications were estimated to reduce the risk of total stroke by 23%.
Researchers also found that increasing fish and nut consumption and reducing unprocessed red meat consumption appeared to have positive impacts on reducing stroke risk, although the degree of impact from these dietary changes was not as big as those achieved through increased physical activity, smoking cessation and maintaining a healthy weight.
While this was an observational study that included mostly white, middle-aged women, Danaei said, "there are other studies to support that the proportional changes in stroke risk from lifestyle and dietary modifications may be generalizable to men. We also estimate that exercising 30 minutes or more daily may reduce the risk of stroke by 20%."

Consuming extra calories can help exercising women avoid menstrual disorders

Exercising women who struggle to consume enough calories and have menstrual disorders can simply increase their food intake to recover their menstrual cycle, according to a study accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in the Journal of the Endocrine Society.
The study found that exercising women with menstrual disorders can start menstruating again by consuming an additional 300-400 calories a day.
"These findings can impact all exercising women, because many women strive to exercise for competitive and health-related reasons but may not be getting enough calories to support their exercise," said lead researcher Mary Jane De Souza, Ph.D., of Penn State University.
By consuming enough calories, exercising women with menstrual disorders can avoid complications associated with a condition known as the Female Athlete Triad, De Souza said. This is a medical condition that starts with inadequate food intake that fails to meet the body's needs. It leads to menstrual disorders and poor bone health. It is associated with a high incidence of stress fractures.
The study included 62 young, exercising women with infrequent menstrual periods. Thirty-two women increased their calorie intake an average of 300-400 calories a day, and 30 maintained their exercise and eating habits for the 12-month study. Women who consumed the extra calories were twice as likely to have their menstrual period during the study compared with the women who maintained their regular exercise and eating routine.
"This strategy is easy to implement with the help of a nutritionist. It does not require a prescription and avoids complications from drug therapy," De Souza said. "The findings will encourage healthcare providers to try to help exercising women with menstrual disorders who consume too few calories to eat more, and this may help them to be healthier athletes and avoid bone complications."
