Trends in cardiovascular disease risk factor prevalence among male transport workers: Bulgaria, 1986 to 1997

Abstract
OBJECTIVES: This study investigated cardiovascular risk factors among male transport workers in Bulgaria. METHODS: Comparisons were made of data from independent surveys conducted among male transport workers aged 30 to 59 years in Sofia, Bulgaria, during 1986 (n = 1146) and 1996-1997 (n = 638). RESULTS: Smoking prevalence increased from 49% to 59% between 1986 and 1996-1997. Among current smokers, the percentage smoking 15 or more cigarettes per day decreased. The prevalence of elevated body mass index, hypertension, or angina pectoris did not change. CONCLUSIONS: Smoking prevalence rates increased during the study period; the prevalence of other risk factors remained high.
