Inactivity after 30 main cause of heart disease in women
Physical inactivity after age 30 may be one of the biggest risk factors of heart disease among women, according to new research.
Scientists collected data on more than 32,000 Australian women who had participated in the Australian Longitudinal Study on Women’s Health, which tracks information on long-term health of women born between 1921 and 1978. Using a mathematical formula and additional data from the Global Burden of Disease study, the researchers then observed the prevalence of the following four known risk factors of heart disease: high body mass index (BMI), smoking, high blood pressure and physical inactivity.
The researchers found that in women under the age of 30, smoking was the biggest risk factor of heart disease. Between ages 30 and 90, however, the biggest risk factor was low physical activity levels. The study’s findings, published in the British Journal of Sports Medicine, suggest that national programs that promote physical activity should be a higher public health priority for women. The World Health Organization (WHO) recommends getting 150 minutes of moderate physical activity each week.
