Percentage differences were tested using cross-tabulation and Chi-Square test. Means were compared by one-way ANOVA, and post hoc tests by Bonferroni correction. Ad. justing with other variables was done by general linear model. BMI = body mass index; MET = metabolic equivalent; LTL = leukocyte telomere length. MET I < 6 METh/week; MET II 6.1-12.0 METh/week; MET III 12.1-22.5 METh/week; MET IV 22.6-45.0 METh/wk; MET V > 45.1 METh/week. p-values are compared to MET I group.Covariate-adjusted for age, fat free mass, smoking, alcohol intake, high sensitive C-reactive protein, educational attainment and marital status.
