ABSTRACT
BACKGROUND: India is an industrialised country and most work is labour intensive. There is very scarce data on occupation related injuries. AIM: To evaluate the prevalence, profile, severity and risk factors for occupational injuries presenting to the emergency medicine department of a tertiary care hospital. MATERIALS AND METHODS: A cross-sectional study was done in the emergency department of Christian Medical College, Vellore among the patients who presented with occupational injuries. The risk factors for occupational injuries like age, gender, shift work, work experience and type of work and their severity and outcome were evaluated. RESULTS: Older age group, working in shift duty, working longer hours were significant risk factors for occupational injuries. CONCLUSION: Training and use of safety protective measures will decrease occupational injuries.
ABSTRACT
BACKGROUND: Occupational health has never been a priority for policy makers in India, despite 63% of the Indian population being in the economically productive age group. OBJECTIVES: The study was designed to find out the morbidity as a result of long-term exposure to pesticides among professional pesticide sprayers in a rural block in Tamil Nadu. SUBJECTS AND METHODS: A cross-sectional study was done in Kaniyambadi block of Vellore district, Tamil Nadu, during July to October 2013. A total of 70 professional pesticide sprayers and 66 people engaged in other occupations were enrolled into the study. The participants were administered a standardized questionnaire apart from measuring pulmonary function and peripheral sensations. Venous blood samples were collected for measuring serum cholinesterase. RESULTS: The pesticide sprayers had higher prevalence of breathlessness on activities of daily living (odds ratio [OR]: 3.14, 95% confidence interval [CI]: 1.22-8.07), chronic cough/phlegm (OR: 3.53, 95% CI: 1.09-11.46), symptoms of peripheral sensory neuropathy (OR: 6.66, 95% CI: 2.53-17.51) and recurrent abdominal pain (OR: 3.05, 95% CI: 1.03-9.01), when compared to people engaged in other occupations. Pesticide sprayers also had significantly lower mean peak expiratory low rates and poor peripheral sensations. The serum cholinesterase levels were not statistically different between the groups. CONCLUSION: The pesticide sprayers had a higher morbidity when compared to people engaged in other occupations, and further research is needed to find out methods to prevent the same. Serum cholinesterase may not be a good marker for quantifying exposure to pesticide among sprayers, during a spraying season.
ABSTRACT
BACKGROUND: A variety of musculoskeletal disorders and discomfort are seen among brick kiln workers, where heavy physical work is associated with awkward working postures and manual handling of materials, leading to significant morbidity. MATERIALS AND METHODS: This cross-sectional study was conducted in unorganized brick kiln industries in villages of Vellore district of Tamil Nadu and included 310 brick kiln workers. Modified Nordic Questionnaire was used to survey the prevalence of musculoskeletal disorders and the intensity of pain was assessed by the body pain discomfort scale. RESULTS: The mean age of the workers was 37 ± 13.2 years with a range of 18-85 years. 62% (n = 192) had normal body mass index, whereas 27% (n = 85) were undernourished. The commonest posture adopted at work was squatting (67%) followed by standing (14%). Majority of workers (87%, n = 269) reported to having symptoms of pain currently of which 51% (n = 158) had pain during work. Chronic low back ache (LBA) (1 year prevalence -59%) and acute LBA (1 week prevalence-33%) were the commonest followed by chronic knee pain. More than 10 years of work was significantly associated (P < 0.05) with acute LBA and acute and chronic knee pain. Severity of the pain was also significantly (t statistic 2.476, P < 0.05) associated with job dissatisfaction. CONCLUSION: Long-term brick kiln workers, who adopt a specific posture for prolonged periods, have severe musculoskeletal pain that interferes with activities of daily living and reduces job satisfaction. Health education on frequent postural change, implementation and monitoring of laws among unorganized industries are recommended to bring down morbidity due to musculoskeletal disorders (MSD).
