Life-Long Physical Activity Involvement and the Risk of Ischemic Stroke in Southern China

Abstract EN

A case-control study was conducted in southern China to investigate the relationship between life-long physical activity involvement and the risk of ischemic stroke.

Information on life-long physical activity exposure and other lifestyle characteristics was obtained from 374 incident stroke patients and 464 hospital-based controls using a validated and reliable questionnaire.

Logistic regression analyses were performed to assess the association between life-long physical activity involvement and the ischemic stroke risk.

The control subjects reported more involvement in physical activity over the life course than the stroke patients (P<.001).

The risk of ischemic stroke was inversely associated with life-long physical activity exposure, with adjusted odds ratio 0.39 (95% confidence interval 0.25 to 0.59) for participants who had always been involved relative to those who have never been much involved.

The dose-response relationship was also significant (P<.001).

Therefore, being active life long should be encouraged to prevent this major chronic disease.
