bAverage difference in body mass index (BMI) measured in kg/m2 between 2015 and 2019.
cBeta coefficients (β) and 95% confidence intervals (95% CI) obtained by simple linear regression, with the average difference in BMI between 2015 and 2019 as the dependent variable.
dBeta coefficients (β) and 95% confidence intervals (95% CI) obtained by multiple linear regression, adjusted for age (in 2015), with the average difference in BMI between 2015 and 2019 as the dependent variable.
eBeta coefficients (β) and 95% confidence intervals (95%CI) obtained by multiple linear regression. Adjusted for age, region, color, and education (in 2015), with the dependent variable being the average difference in BMI between 2015 and 2019.
