Variable coding: Smoking, smoke exposure and employment–yes = 1, no = 0; TB and HIV–positive = 1, negative = 0; education—graduated from high school = 1, did not graduate = 0; walking—walk > 2km/day = 1, 30 minutes/day; hypertension (HT) was coded using dummy variables with non-treated hypertensives used as the reference group and compared with non-hypertensives and treated hypertensivesMultiple regression models for BMI, waist circumference and blood pressure in male and female subjects.
