Context:
Vulnerable population groups such as migrant workers are identified as emerging high-risk groups for oral cancer owing to the high prevalence of smokeless tobacco consumption. Premature deaths due to oral cancer can be prevented by screening the population with high tobacco consumption practices and detecting early reversible stages of oral mucosal cavity lesions and facilitating linkages for further care.
Aim:
To assess prevalence of potentially malignant oral mucosal cavity lesions among tobacco consuming migrant construction workers in sub-urban Chennai, India.
Settings And Designs:
A workplace based cross-sectional study design.
Materials And Methods:
A cross-sectional study was conducted at workplaces i.e., construction sites for screening potentially malignant oral mucosal cavity lesions among migrant workers across 23 construction sites of Chennai during September 2019 - February 2020. An onsite, group health education session was provided about the harms of tobacco use to the migrants.
Statistical Analysis Used:
Data entered in MS Excel was analysed using SPSS and multivariate analysis was performed.
Results:
Among 640 migrants included in the study, 411 (64.2%) were less than 30 years of age, 623 (97.4%) were from north-eastern states of India such as West Bengal, Bihar, Rajasthan, Uttar Pradesh, Jharkhand. A considerable size (272, 42.5%) could not read or write and 355 (55.4%) earn a monthly income of less than ten thousand rupees. Current tobacco users were 619 (96.7%), smokeless tobacco users (463, 72.34%), smokers (206, 32.2%) and dual users (52,8.12%). Inflammatory mucosal lesions in the oral cavity were 70.97% and more among smokeless tobacco users comparable to 22.58% among tobacco smokers and was significantly associated with up to 20 years of tobacco consumption.
Conclusions:
Prevalence of Potentially malignant oral lesions among smokeless tobacco using interstate migrant construction site workers is very high and need urgent interventions.
