title: Suicide mortality among electricians in the Swedish construction industry.
abstract: OBJECTIVE
  To investigate the risk of suicide in Swedish electricians employed in the construction industry. A few studies have indicated an increased risk of suicide for electricians in the construction industry and electricians exposed to electromagnetic fields.
  
  
  METHODS
  This is a cohort study. Electricians were identified through a computerised register of construction workers who had participated in health examinations in 1971-92. In this register, 33,719 male electricians were identified together with a reference group consisting of 72,653 male glass or woodworkers. Through a linkage with the Swedish Death Register, the cause of death was identified to the end of 1997. Mortality as a result of suicide was also compared with the general population with adjustments for sex, age, and period.
  
  
  RESULTS
  The risk of mortality from suicide was decreased for electricians (standardised mortality ratio (SMR) 0.58, 95% confidence interval (95% CI) 0.47 to 0.71) and for the reference group of construction workers (SMR 0.81, 95% CI 0.72 to 0.91) compared with the general population.
  
  
  CONCLUSIONS
  Contrary to some other studies, risk of suicide was not increased among electricians in the construction industry.
