Prevalence of Tobacco Use in Urban, Semi Urban and Rural Areas in and around Chennai City, India

PLOS ONE, Dec 2019

Background Tobacco use leads to many health complications and is a risk factor for the occurrence of cardio vascular diseases, lung and oral cancers, chronic bronchitis etc. Almost 6 million people die from tobacco-related causes every year. This study was conducted to measure the prevalence of tobacco use in three different areas around Chennai city, south India. Methods A survey of 7510 individuals aged > = 15 years was undertaken covering Chennai city (urban), Ambattur (semi-urban) and Sriperumbudur (rural) taluk. Details on tobacco use were collected using a questionnaire adapted from both Global Youth Tobacco Survey and Global Adults Tobacco Survey. Results The overall prevalence of tobacco use was significantly higher in the rural (23.7%) compared to semi-urban (20.9%) and urban (19.4%) areas (P value <0.001) Tobacco smoking prevalence was 14.3%, 13.9% and 12.4% in rural, semi-urban and urban areas respectively. The corresponding values for smokeless tobacco use were 9.5%, 7.0% and 7.0% respectively. Logistic regression analysis showed that the odds of using tobacco (with smoke or smokeless forms) was significantly higher among males, older individuals, alcoholics, in rural areas and slum localities. Behavioural pattern analysis of current tobacco users led to three groups (1) those who were not reached by family or friends to advice on harmful effects (2) those who were well aware of harmful effects of tobacco and even want to quit and (3) those are exposed to second hand/passive smoking at home and outside. Conclusions Tobacco use prevalence was significantly higher in rural areas, slum dwellers, males and older age groups in this region of south India. Women used mainly smokeless tobacco. Tobacco control programmes need to develop strategies to address the different subgroups among tobacco users. Public health facilities need to expand smoking cessation counseling services as well as provide pharmacotherapy where necessary.

Tobacco is used in forms either designed for smoking or for non-smoking routes. Tobacco use alone is currently ranked fourth in the world in its contribution to years of life lost [1]. The smokeless forms of tobacco are used mostly in developing countries, especially those in south East Asia. In India, tobacco is smoked as a cigarette, beedi (a thin, Indian cigarette filled with tobacco flake and wrapped in a tendu leaf tied with a string at one end) cheroot (a cigar cut square at both ends), or in a pipe. The smokeless forms of tobacco are chewed as raw tobacco leaves or panmasala (a mixture of arecanut, tobacco and other ingredients), or inhaled as snuff. Tobacco use is considered to be one of the chief preventable causes of death in the world. Globally, smoking causes about 71% of lung cancer, 42% of chronic respiratory diseases and about 10% of cardiovascular disease. It is responsible for 12% and 6% of male and female deaths respectively [2]. In India, it was reported in 1990 that 1.5% of the total deaths were tobacco related [3]. Tobacco continues to kill 6 million people each year globally, including more than 600000 non-smokers who die from exposure to tobacco smoke [4]. The chewing of tobacco products is a risk factor for oral cancers [5]. Further, tobacco consumption was found to be higher among the lower socioeconomic groups [6]. Basic data on tobacco use at the national level is available from the National Family Health Surveys [7] (a large scale, multi-round survey conducted in a representative sample of households in India). To estimate tobacco use among school children in the 8th grade to 10th grade (ages 13 to 15 years) and adults (of age .15 years), nationwide Global Youth Tobacco Survey (GYTS) [8,9] and Global Adult Tobacco Survey (GATS) have been conducted [10]. However, there is limited data on the social and behavioural factors that influence the use of various forms of tobacco and attitudes of tobacco users towards quitting the habit. Accordingly a study was planned and conducted in urban, semiurban and rural populations residing in and around Chennai city in the southern Indian state of Tamilnadu to estimate: a) the prevalence of use of various forms of tobacco (cigarette/beedi smoking, smokeless chewing tobacco or snuff) and study the factors that influence use of tobacco. Behavioural patterns of tobacco use among the adult population are described, based on their knowledge, attitude and practice as captured in the questionnaire adapted fr (...truncated)
