Smoking tobacco is a major contributor to the global cardiovascular disease burden. India bears a huge part of this burden and it is estimated that nearly a quarter million individuals aged >15 years consume tobacco in India. Moreover, about 70% of tobacco deaths are reported to be in the age range of 30-69 years.
Motivational interviewing (MI) is an innovative manner of communication which puts the focus on the patient and strengthens their motivation for behavior change without overt confrontation or persuasion. MI delivered by community health workers (CHW) is part of the strategy planned by the investigators.
In order to deliver personalized assistance and increase penetration of the required intervention into different parts of the country, text messaging is a promising strategy in low and middle-income countries but there is no data regarding its application for tobacco use in India.
The investigators plan to screen 560 individuals between the age of 18 and 70 years for smoking from 16 randomly selected clusters in the economically backward urban towns of Dalkhola (West Bengal) and Jabalpur (Madhya Pradesh). The screening will be done using house to house visits by CHWs who will administer a questionnaire based on the WHO STEPS survey. An individual identified as a chronic tobacco user irrespective of his/her stage of behavior change will be eligible for further participation in the study and assigned to the appropriate intervention arm. Clusters will be randomized to either receive the combined intervention or usual care.
Apart from screening and recruitment, CHWs will be responsible for differentiating individuals between being pre-contemplative vs contemplative. Based on their readiness to quit, participants will receive a structured intervention which involves motivational interviewing delivered by the CHW in their homes and weekly support provided through regular mobile text messages.
The CHWs will be chosen from the study population based on a set of criteria through a formal selection panel after consulting with the local leaders and physicians. They will undergo a week of training for the screening process, an additional week for the intervention and finally a refresher course every 6 months.
The text messages are selected from a pre-determined database of messages and the content of which changes based on the individual's stage of behavior change. The messages are delivered automatically every other day of the week and are controlled by the investigators in Cleveland, Ohio, USA.
The control group, during their screening visit, will be informed of their problems, given a brief pamphlet and encouraged to seek physician help.
The investigators hypothesize that a community health worker based intervention, utilizing motivational interviewing and health education, coupled with text messaging based support will lead to increased quit rates amongst participants who are daily smokers.
At the end of one year, the self-reported abstinence of the participants in the intervention arm will be recorded and biochemically verified with a carbon monoxide breath analyzer test.

Experimental: Motivational Interviewing/Text messaging
Home visits by community health worker to deliver motivational interviewing and set up a structured text messaging strategy designed around a pre-determined quit date for smoking cessation.
Behavioral: Motivational Interviewing/Text messaging
The intervention is a multi-component one that is tailored to the individual and will target smoking cessation. The CHW, after identifying the individual's stage of behavior change, will provide motivational interviewing and set up an automatic text messaging system with their mobile phones that are structured around a quit date chosen by the participant.
The CHW visits are pre-determined and she monitors the progress of the individual regularly. She may restart the process of determining the stage of behavior change for those who relapse or quit the intervention midway thereby reassigning them to the appropriate phase of the trial
No Intervention: Control
All participants will receive brief verbal advice about the hazards of smoking and the benefits of smoking cessation.
- Quit rate at the end of 1 year [ Time Frame: 1 year ]Self-reported abstinence, biochemically verified, for the past 14 days at the end of 1 year from the start of the intervention.
- Relapse rate at the end of 1 year [ Time Frame: 1 year ]The number of individuals who have relapsed into smoking after completing the intervention at the end of 1 year.
