Healthy lifestyle reduces sudden cardiac death in women

These US researchers the effect of healthy lifestyle on the risk of sudden cardiac death (SCD) women. The performed a prospective cohort study of women enrolled in the Nurses' Health Study (n=81 722). They examined lifestyle factors using questionnaires, defining a low-risk lifestyle as being a non-smoker, having a body mass index of 25 or less, exercising at least 30 minutes per day, and a diet in the top 40% of the alternate Mediterranean diet score.

The researchers found: "All 4 low-risk lifestyle factors were significantly and independently associated with a lower risk of SCD. The absolute risks of SCD were 22 cases/100,000 person-years among women with 0 low-risk factors, 17 cases/100,000 person-years with 1 low-risk factor, 18 cases/100 000 person-years with 2 low-risk factors, 13 cases/100,000 person- years with 3 low-risk factors, and 16 cases/100,000 person-years with 4 low-risk factors. Compared with women with 0 low-risk factors, the multivariable relative risk of SCD was 0.54 for women with 1 low-risk factor, 0.41 for 2 low-risk factors, 0.33 for 3 low-risk factors, and 0.08 for 4 low- risk factors. The proportion of SCD attributable to smoking, inactivity, overweight, and poor diet was 81%. Among women without clinically diagnosed coronary heart disease, the percentage of population attributable risk was 79%."

The researchers concluded: "Adherence to a low-risk lifestyle is associated with a low risk of SCD."
