Unravelling India's tobacco epidemic--priorities and recommendations for the second round of Global Adult Tobacco Survey (GATS).

The Global Adult Tobacco Survey, or GATS, has proved to be an invaluable tool for policymakers. In India, it highlighted the alarming rates of prevalence of use and risks both nationally and at state level. However, a rapid analysis of GATS-India shows that there are limitations in methods (sampling, questionnaire, measures undertaken to ensure data quality and management), which may impact the estimates of prevalence. This review discusses these potential weaknesses and recommends measures that can be adopted in the next round of surveys to overcome the limitations.
