Aims

A population-based study of 1046 young Finnish men was performed to evaluate whether body composition changes observed during military service are associated with a reduction in prevalence of metabolic syndrome (MetS), and whether the effect is body mass index (BMI)-dependent.

Methods

A prospective study of 1046 men (mean age 19.2 years, SD 1.0), with follow-up during 6-12 months of military service in northern Finland. Anthropometry, body composition, biochemical measurements and physical fitness were assessed at baseline and follow-up. MetS was defined using the International Diabetes Federations (IDF) criterion, continuous MetS Z-score calculated, and changes evaluated in BMI categories.

Results

Prevalence of MetS at baseline and follow-up was 6.1 % and 3.6 % , respectively (p < 0.001). Prevalence of MetS decreased by 40 % (p < 0.001) among the obese young men (BMI ¡Ý 30 kg/m²). Reduction in the MetS Z-score was mainly attributable to weight loss and reduced fat mass (p < 0.001) and improvement in physical fitness (muscle fitness index, p = 0.016).

Conclusions

Beneficial exercise-induced changes in body composition significantly reduced the prevalence of MetS among young, obese men. Our findings support the efficacy of increased physical activity for prevention of early-onset cardiovascular disease, particularly among overweight and obese young men.
