Body mass index, physical activity, and smoking in relation to military readiness

Abstract

The objective of the study was to analyze the influence of excess weight, regular physical activity, and smoking on the military readiness of the Belgian Armed Forces in a cross-sectional online survey. A multinomial logistic regression was used to study the influence of modifiable risk factors on participation in the physical fitness test. In our study population (n = 4,959), subjects with a body mass index higher than 25 kg/m(2), smokers, and subjects with a lower level of vigorous physical activity were significantly more likely to have failed the physical fitness test. In the Belgian Armed Forces, serious efforts should be made to encourage vigorous physical activity, smoking cessation, and weight loss to preserve our military readiness. Instead of relying on civilian public health interventions, Belgian Defense should develop its own specific approaches to prevent weight gain, improve physical fitness, and influence smoking attitude.
