  1. BSRM Body system related morbidity, PR Prevalence rate, CI Confidence interval
  2. aThe association of age and BMI group with BSRM was assessed by using Poisson regression. The dependent variable was defined as the total number of BSRM (range from 0 to 8). Model adjusted for sex, socioeconomic status (low, medium, and High), and ethnicity (Israeli-born Jewish, European-born Jewish; Middle Eastern-born Jewish; Americas-born Jewish; former USSR-born Jewish; Ethiopian-born Jewish; Arab; missing)
  3. bThe association of age and BMI group with annual cost burden was assessed by using linear regression. The dependent variable was defined as log(x + 1) transform of the estimated annual cost burden using a Clalit cost compendium. Model adjusted for sex, socioeconomic status (low, medium, and High), and ethnicity (Israeli-born Jewish, European-born Jewish; Middle Eastern-born Jewish; Americas-born Jewish; former USSR-born Jewish; Ethiopian-born Jewish; Arab; missing)
  4. cRetransformation adjustment (exp β) was performed in going from the log model to estimates of Clalit cost compendium (NIS)
