  1. BMI body mass index; CI confidence intervals; df degrees of freedom
  2. *ANOVA for the difference between the groups. Bonferroni test 27–34 vs. 35–44 (p = 0.035), 45–54 vs. 55–64 (p = 0.013), p < 0.01 for all other pairwise comparisons between the age groups
  3. **ANOVA for the difference between the groups. Bonferroni test: did not complete high school vs. completed high school (p = 0.055). Did not complete high school vs. academic degree (p = 0.033). Completed high school vs. academic education (p = 1.0)
  4. ***ANOVA for the difference between the groups. Bonferroni test p > 0.2 for all pairwise
