title: [Job strain and hypertension risk in Capital Steel and Iron Company in Beijing].
abstract: OBJECTIVE
  To assess the relation between the scales of Job Demand control Model (or "Job strain") and the prevalence of hypertension.
  
  
  METHODS
  A standardized questionnaire base-line survey was conducted among 1,556 male and female employees aged 18-65 in two factories of the Capital Steel and Iron Company, Beijing, in 1997 to investigate the socio-demographic factors and job strain so as to identify the major risks of hypertension.
  
  
  RESULTS
  The prevalence of hypertension increased from 6.5% to 21.2% with an age-adjusted relative prevalence ratio (95% CI) of 3.26 (2.30, 4.41) when the job strain pattern changed from high control and low demand to moderate control and moderate demand and further to low control and high demand among the male employees. After adjustment for confounding effects from age, education, body mass index, smoking, alcohol consumption, and physical activity, the odds ratio (95% CI) was attenuated to 2.31 (1.45, 3.81). Such a phenomenon was not typical among females.
  
  
  CONCLUSIONS
  The risk of hypertension was elevated with the increase of job strain in men.
