 To obtain a designbased pooled prevalence estimate across all 5 CCHS cycles, the cyclespecific survey weights for each respondent were rescaled based on the proportion that cycle contributed to the total weighted pooled population using Statistics Canada’s Bootvar program (1). The rescaled weights were used to calculate the designbased prevalence estimates. The modelbased prevalence estimates were aggregated to the micro area using poststratification methods (see Additional file 1). The mean risk factor prevalence was calculated for each county, as well as the entire region (LHIN) for both models. Model 1 results are comparable to the designbased estimates, which do not adjust for income
 a The interval of variation of the designbased prevalence estimate is expressed as a 95 % confidence interval (CI). bThe interval of variation of the Bayesian modelbased prevalence estimate is expressed as a 95 % credible interval (CI).
