Prevalence of current and former smoking in industrial workers worldwide: a systematic review and meta-analysis

Abstract

Objectives

One of the health problems in recent decades is the prevalence of smoking in the world. In this study, the global prevalence of smoking in industrial workers was investigated using meta-analysis.

Method

The method of the present study was a systematic review and meta-analysis. Three scientific sources, PubMed, Web of Science, and Scopus, were selected for the search, and these databases were searched until September 2020. Random effects method was used for the analysis and then the analysis was performed for the type of smoking (Current, Former), gender, and continent. Heterogeneity was examined in all analyses.

Result

A total of 88 studies were included in the meta-analysis. The prevalence of smoking in industrial workers was 41% also the confidence interval was 35–48%. The prevalence of current smoking in industrial workers was 39% also the confidence interval was 29–48%. The prevalence of former smoking in industrial workers was 18% also the confidence interval was 13–22%. I² heterogeneity test was 99.9%.

Discussion

From the findings of the present study, it can be seen that industrial workers are more exposed to smoking compared to the general population, and this can put their health at greater risk.
