The reduced number of participants is due to selective missing data.
For men, age, employment, marital status, family history of hypertension, smoking, alcohol intake, physical activity index, body mass index, and job strain were included in the model.
For women, age, education, family history of hypertension, smoking, body mass index, and job strain were included in the model. Each factor adjusted for each other factor.
Age is coded from 1 (⩽35) to 4 (56–65). Smoking habits are coded from 1 (never smoker) to 4 (smoked cigarettes ⩾21/day) for men, and from 1 (never smoker) to 3 (current smoker) for women. Alcohol intake is coded from 1 (never and ex-drinker) to 4 (drank ⩾86.7 g/day of alcohol). Physical activity index, body mass index and job strain are coded from 1 (the lowest level) to 3 (the highest level).
The OR values for variables with more than two categories were the ORs for each step.
Reference categories of the dichotomous variables are white collar workers, currently married, higher educational level, and no family history of hypertension.
