Levels of physical activity may outweigh CVD risk due to overweight and obesity

Impact of physical activity on the association of overweight and obesity with cardiovascular disease: The Rotterdam Study

Background

Overweight and obesity are associated with an increased CVD risk, whereas higher levels of physical activity (PA) are associated with a decreased CVD risk [1-6]. However, it is not clear to what extent PA can counterbalance the CVD risk associated with overweight and obesity.

In this study, the role of PA in the association between BMI and CVD was evaluated, in middle-aged and elderly participants, based on data from the large population-based Rotterdam

Study, with 5344 participants who were followed for 15 years. Intensity of activity was quantified using metabolic equivalent of task (MET) scores to all activities. Normal weight with high levels of PA was used as the reference category in all analyses including BMI, PA as well as CVD.

Main results

Conclusion

In this long-term follow-up study, only overweight and obese participants with low PA, and not those with high PA, were at increased risk for CVD, when compared to participants with normal weight. These findings suggests that regular PA reduces CVD risk in these individuals and that further benefits can be gained from maintaining a healthy weight.
