Exercise intervention and health checks for middle-aged men with elevated cardiovascular risk: a randomized controlled trial.

OBJECTIVE

To study the effects of a health check by a nurse alone or combined with an exercise intervention in middle-aged men at increased cardiovascular risk.

DESIGN

A randomized controlled trial.

SETTING AND INTERVENTION

Primary care in Kirkkonummi municipality with 36 000 inhabitants. A health check by a nurse alone or combined with an exercise intervention to controls with no intervention was compared.

SUBJECTS

A total of 168 men aged 35 to 45 years with at least two cardiovascular risk factors and physical activity (PA) frequency < 3 times a week.

MAIN OUTCOME MEASURES

Metabolic syndrome (MetS) as defined by International Diabetes Federation/American Heart Association and self-reported PA frequency.

RESULTS

Overall, focusing on health increased physical activity frequency in middle-aged men. After one year, 19% had increased PA to ≥ 3 times a week (95% CI 12-26). All study groups increased PA to ≥ 3 times: 26% of men in the exercise intervention group, 15% of men in the health check group, and 16% of controls. The differences between the groups were not statistically significant. The intervention did not have any meaningful impact on MetS or other cardiovascular outcomes at one-year follow up.

CONCLUSIONS

Physical activity increased in all study groups of middle-aged men in this health-promotion trial. The interventions had no effect on metabolic syndrome or other cardiovascular outcomes in the participants. The trial increased awareness and collaboration in physical activity promotion among municipal health care and exercise services.
