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, and body mass index were adjusted for in the model. For the analysis in the employment strata, employment status was not included as an independent variable.
For women, age, education, family history of hypertension, smoking, body mass index were adjusted for in the model. For the analysis education was not included as an independent variable.
Job strain is coded from 1 (the lowest level) to 3 (the highest level).
