  1. National Health Telephone Interview Survey “German Health Update (GEDA)” 2009).
  2. Estimates of 12-month prevalence (%) and their 95% confidence intervals (95% CI) were weighted according to German population statistics (December 31, 2007).
  3. # including 101 (1%) under-weighted subjects whose body mass index (BMI) is less than 18.5 kg/m2.
  4. * p < .05, ** p < .01, *** p < .001, derived from Rao-Scott chi-square tests for the difference of prevalence estimates within specific group.
  5. Adjusted and unadjusted odds ratio (OR) and 95% confidence intervals (95% CI) were derived from logistic regression models. Variables in the adjusted logistic regression model include all variables listed in Table 1.
