Effectiveness of anti-smoking interventions towards community: a meta-analysis study

Smoking is one of the biggest public health problems in the world. The World Health Organization (WHO) has declared the MPOWER package which provides a guide for tobacco control. The package includes six evidence based anti-smoking interventions. This meta-analysis study aims to assess the effectiveness of MPOWER - (M)onitor, (P)rotect, (O)ffer, (W)arn, (E)nforce, and (R)aise. In the study, "smoking prevalence rate, smoking cessation rate and number of cigarettes smoked daily" outputs were used in adult and adolescent age groups.

Literature search has been made with "smok*, tobacco, cigarette*" keywords from the databases of Medline, Web of Science, Scopus, and Cochrane-Library. Abstracts were assessed in detail according to the inclusion criteria by the research team. Quality of articles was evaluated with modified Jadad criteria. The follow-up periods of articles were determined in two groups named as short and long term periods. We used random effects model (p ≤ 0.05) and fixed effects model (p > 0.05) according to the heterogeneity test results.

P and O interventions, which are evaluated with smoking cessation rate, increased the smoking cessation rate in adults by 39% in the longest follow-up period - RR: 1.39 (1.23-1.57). However, it was determined that the interventions were not effective on smoking cessation rate in adolescents - RR: 1.13 (0.90-1.42). Nicotine replacement therapy (NRT) was the most effective intervention for smoking cessation rate in adults. W interventions, which are evaluated with smoking prevalence rate, decreased the smoking prevalence rate in adults by 13% in the longest follow-up period - OR: 0.87 (0.82-0.92). P, W and E interventions, which are evaluated with smoking prevalence rate, decreased the smoking prevalence rate in adolescents by 26% in the longest follow-up period - OR: 0.74 (0.68-0.80).

MPOWER interventions affect smoking prevalence rate, smoking cessation rate and number of cigarettes smoked daily in different age groups. Well-controlled, well-planned and cost-effective anti-smoking interventions have great importance for public health protection.
