title: Epidemiology of venous insufficiency in an occupational population.
abstract: OBJECTIVE
  A cross sectional study of the prevalence and risk factors of chronic venous insufficiency (CVI) in a South European occupational population was performed.
  
  
  METHODS
  Over a 7-month period a questionnaire (CVI symptoms, general data and life style habits) was administrated to 1604 consecutive females (73.3%) and 586 consecutive males (26.7%). An oriented clinical examination was then performed. Subjects were classified into 4 groups: asymptomatic, light, moderate and severe CVI. Univariate and multivariate analysis were used.
  
  
  RESULTS
  Mean age 38.8+/-11.6 years (range 15-65). The prevalence of CVI all classes confounded was 51.4% (62.3% in women and 21.8% in men); the prevalence of moderate and severe CVI was 10.4% (12.1% in female and 6.3% in male). Age (Odds Ratio (OR): 1.93, 95% confidence interval (CI): 1.55-3.53), female sex (OR: 2.34, 95% CI: 1.62-2.30), obesity (kg/m(2)) (OR:1.11, 95% CI: 1.07-1.15) and familial history of CVI (OR: 2.80, 95% CI: 2.02-3.89) were risks factors of moderate and severe CVI. The comparison extended to the whole group of CVI added other risk factors: history of leg injury, pregnancy; a sitting posture at work. Unexpectedly smoking had a protective effect but only in the female group for the last one.
  
  
  CONCLUSIONS
  CVI is an important medical problem concern in this population. Some of the risk factors like obesity and standing position at work may benefit from preventive measures.
