Table 1.
Age, anthropometric data, body composition (weight, height, BMI, lean and fat mass measured with DEXA, fat cross-sectional area (CSA) measured with pQCT), physical activity and smoking habits. Comparison of these characteristics in the two subject groups. Values are means ± Standard Deviations (p-values result from an independent t-test), only the present smoking status is reported in % (p-value results from chi-square test).
