Abstract
BACKGROUND: Lead poisoning is one of the most common preventable paediatric and occupational health problems today. It accounts for 0.6% of the global burden of disease. The weight of evidence of its damaging effects on health and the environment is overwhelming. In India, many studies have been conducted to estimate the burden of lead poisoning and its risk factors, which have shown that even after decline in leaded petrol, lead poisoning continues to be public health problem. Painters are continuously exposed to lead containing paints during painting. This study aims to assess the prevalence and risk factor for elevated blood lead level among residential and automobile painters. OBJECTIVES: 1. To assess the prevalence of elevated blood lead levels among people involved in residential and automobile painting occupation from rural and urban areas of Vellore. 2. To identify factors associated with elevated blood lead levels among painters from rural and urban areas of Vellore. 3. To study the associated health effects due to elevated blood lead levels among the people involved in painting occupation from rural and urban areas of Vellore. MATERIAL AND METHODS: A community-based cross-sectional study was conducted among people primarily involved in residential and automobile painting occupations residing in rural and urban areas of Vellore. A total of 150 study participants were chosen by simple random sampling from a list of residential painters and automobile painters collected from various sources. After obtaining written informed consent a pilot tested semi structured interviewer administered questionnaire was used to obtain information on socio-demographic details and lifestyle measures among painters. Anthropometry measurements, vitals, complete clinical examination and laboratory blood investigations (Blood lead level, Hb, SGPT, creatinine) were done for all subjects. Data entry was done using Epidata- Version 3.1 and analysed using Statistical Package for Social Sciences (SPSS 24.0). RESULTS: • According to the revised CDC guideline value of 10mcg/dl, 35.7% (52) of the 147 study participants had elevated blood lead levels. • Prevalence among residential and automobile painters i. Residential painters (n=114) ▪ 20.2% of study participants had BLL above 10μg/dl. ii. Automobile painters (n=33) ▪ 67.8 % of study participants had BLL above 10μg/dl. • On performing bivariate analysis age (<40 years), socioeconomic status (lower), area of residence (urban), material used to paint house, type of roof, use of kajal/Surma, occupation involved, man hours at work, painting method, method to mix paints, dispose of empty cans and inappropriate use of personnel protective equipment were potential risk factors for elevated BLL. • Multivariate analysis after adjusting for potential confounders study participants involved in automobile painting [adjusted OR=12.56,95% CI (2.53-62.24)], manhours involved in painting [adjusted OR=0.38,95% CI (0.14-0.99)], people living under concrete roof [adjusted OR=0.35,95% CI (0.12-0.96)] were potential risk factors for elevated BLL. CONCLUSION: From this study, it was concluded that the prevalence of elevated blood lead level among residential and automobile painters continuing to be a major public health problem. Findings also depict that people involved in automobile painting are at higher risk of having elevated blood lead level when compared to automobile painters. RECOMMENDATIONS: Painters and people in similar occupations should have periodical health examination and laboratory testing; should be a component of primary health care program. Use of personal protective equipment’s should be encouraged.
