Abstract：ObjectiveTo investigate the quality of life of lead exposed workers in Shaoguan City and analyze its influence factors. Methods During November 2013 and July 2015 we used cluster sampling to recruit 670 lead-exposed female workers from nine lead-relevant companies in Shaoguan City, including non-ferrous metal ore concentrating mills, smelting enterprises, lead-acid battery business. A survey was conducted by self-made questionnaire and WHO Quality of Life-BREF (WHOQOL-BREF). Their quality of life was assessed. The influence of age, education level, marital status, occupational history and basic situation of their jobs on their quality of life were sstatistically analyzed by t test, ANOVA, rank-sum test and linear trend test. Results The scores of the lead exposed female workers in Shaoguan City in four domains(physiological domain: 14.50±1.54; psychological domain: 12.93±1.40; social domain: 12.80±1.30; environment domain: 11.70±1.79) were significantly lower than those of the national norm (P＜0.05). The scores in social and psychological domains increased with the increment of the average monthly income(P＜0.05). The female workers who wore effective personal protective equipment as required by work got higher scores in psychological domain (13.38±1.43) than those who did not (13.05±1.41) (P＜0.05). The female workers who had ≤5 working days per week scored higher in psychological and social domains (13.05±1.48 and 12.86±1.35) than those who had ＞5 working days per week (12.81±1.38 and 12.44±1.28) (P＜0.05). The scores in psychological and environment domains of the female workers whose workplaces were equipped with protective measures(13.08±1.43 and 11.86±1.86 ) were significantly higher than those of the workers whose workplace were not (12.82±1.42 and 11.48±1.73) (P＜0.05). The scores in physiological domain of the female workers who were aged ＜30 or 30~ years (15.00±1.51 and 15.30±1.50 )were higher than those who were aged 40~ or 50~ years (14.30±1.56 and 14.28±1.55 ) (P＜0.05). There are significant differences in the scores of social and psychological domains among female workers with different marital status (P＜0.05). In the psychological domain, the unmarried(13.26±1.42) and married(13.04±1.39) scored higher than the divorced or widowed(12.58±1.41)(P＜0.05). In the social domain, the married(13.08±1.31)scored higher than the unmarried(13.02±1.29)and divorced or widowed(12.38±1.30)(P＜0.05). Conclusions The overall quality of life of the lead-exposed female workers in Shaoguan City is poor. It is influenced by marital status, age,monthly income,working days per week,wearing of effective personal protective equipment as required in work and equipment with protective measures in workplaces. Comprehensive measures should be taken to improve their quality of life.
