Objective: Nearly 300 million people in India use some type of tobacco product, with about 60% of those using smokeless tobacco. Smokeless tobacco use has been associated with a number adverse health outcomes in India and across South Asia.
Method: A cross-sectional study of outpatients at a dental hospital in Navi Mumbai, India was conducted between January and June 2015. Trained interviewers administered a 19-item questionnaire to all patients receiving regular dental care. In addition to demographic information, data about the use of smokeless tobacco was collected. Nicotine dependence was assessed using the six-item Fagerstrom Nicotine Dependence Scale, adapted for smokeless tobacco.
Results: Approximately one third of 1,067 respondents (30.55%; N = 326) reported use of smokeless tobacco. Neither use of smokeless tobacco nor nicotine dependence was associated with any demographic variables. High nicotine dependence was associated with a younger age of initiation of smokeless tobacco use (RD = 0.14; 95% CI: 0.03, 0.25) and with frequency of use, with those who reported daily use having an excess risk of high nicotine dependence of 14% (95% CI: 2%, 27%).
Conclusion: To reduce dependence on smokeless tobacco in India and subsequent adverse health outcomes, interventions should emphasize a combination of policy and public health interventions focused on increasing the age at which a person initially uses smokeless tobacco and decreasing the frequency of use.
