BP, blood pressure; SBP, systolic BP; SEP, socioeconomic position.
Model 1 adjusts for age and sex; Model 2 adjusts for variables in Model 1 plus hypertension status; and, Model 3 adjusts for variables in Model 2 plus behavioral and anthropometric risk factors. Model 4 adjust for the variables in Model 3 plus office SBP. Model 5 adjusts for the variables in Model 4 plus mean 24-h SBP.
