Current Trends and Impact of Smoking Cessation Interventions for Adult Smokers in Low and Middle Income Countries: A Systematic Literature Review

Abstract

Objective: This study aims to systematically review the existing literature on the current developments and impact of smoking cessation interventions targeted toward adult smokers in low and middle income countries (LMICs).Methods: Major databases were searched with the following selection criteria: (1) studies based on empirical findings that demonstrate the impact of smoking cessation interventions in LMICs; (2) studies conducted in or focused on LMICs; (3) studies targeted at the adult smoking population; (4) studies focused on smoking cessation component of tobacco control; (5) studies that reported on the capacity for smoking cessation intervention and current developments in LMICs; (6) published in peer review journals between 2003 and April, 2013; (7) studies written or transcribed in English.Results: A total of 23 articles (23 studies) were included in the review. Six studies assessed the effectiveness and cost-effectiveness of smoking cessation intervention types in some LMICs. Four studies explored the reach, adoption and institutionalisation of cessation interventions. Six studies assessed physicians’ capacity to provide cessation interventions, and seven studies provided insights on current developments.Conclusion: Smoking cessation interventions are not readily available and affordable in LMICs. Extensive research is needed to determine the most cost-effective and culturally appropriate smoking cessation interventions for adult smokers in LMICs.
