- NHANES National Health and Nutrition Examination Survey, CI Confidence interval. The weighted quantile sum (WQS) regression was fitted for the obesity and BMI z-score, which scored all the chemical exposures into quantiles and estimated the weight index. OR estimates represent the odds ratios of obesity as 1 quartile increased in the WQS index. β estimates represent the mean differences in the BMI z-score as 1 quartile increased in the WQS index. Model 1: Adjusted for age, gender, ethnicity, and log-transformed creatinine. Model 2: Adjusted for age, gender, ethnicity, caloric intake, serum cotinine, and log-transformed creatinine. Model 3: Adjusted for age, gender, ethnicity, educational levels, family income-to-poverty ratio, caloric intake, serum cotinine, and log-transformed creatinine
