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