Work conditions as risk factors for varicose veins of the lower extremities in certain professions of the working population of Rijeka.

This research aims to establish the effect of working conditions on the appearance of varicose veins. The epidemiological study was carried out on 1,324 examinees, 530 males and 794 females, employed in 5 highly represented groups of professional activities in Rijeka (catering, trade, light industry, heavy industry and finances). The data were collected by survey and clinical examination. Varicose veins were more prevalent in the trade than in the office workers (odds ratio (OR) = 2.08; 95% confidence interval (CI) = 1.31-3.31), and more prevalent in catering industries than in the office workers (OR = 1.56; 95% CI = 1.001-2.43). chi 2-testing suggested that standing in the workplace (OR = 1.35; 95% CI = 0.95-1.92), weight handling while working (OR = 1.29; 95% CI = 1.01-1.64) and working indoors (OR = 1.61; 95% CI = 1.02-2.53) were risk factors for varicose veins. By multiple logistic regression, the following risk factors were isolated in the total population: female sex (OR = 1.92; 95% CI = 1.37-2.67), workplace (OR = 0.89; 95% CI = 0.78-0.99), age (OR = 1.05; 95% CI = 1.03-1.07), body mass index (OR = 1.04; 95% CI = 1.01-1.07) and family history of the disease (OR = 1.99; 95% CI = 1.55-2.57).</p
