Prevalence and Factors Associated with Current Cigarette Smoking among Ethiopian University Students: A Systematic Review and Meta-Analysis

الملخص EN

Background.

Although tobacco use is highest in high-income countries, most tobacco-related deaths occur in low- and middle-income countries with the highest number of deaths recorded in East Africa.

The aim of this systematic review and meta-analysis is to determine the pooled prevalence and associated factors of current cigarette smoking among Ethiopian university students.

Methods.

The authors searched databases from PubMed, PsycINFO, Google Scholar, EMBASE, and Web of Sciences.

The publications included in the analysis were inclusive, the literature was searched from January 2011 to December 2018.

The JBI-MAStARI critical appraisal tool was applied to 13 publications identified by the database search.

I2 statistics were used to indicate heterogeneity.

Publication bias was evaluated using the visual funnel plot.

A p value < 0.1 was considered as indicative of statistically significant publication bias.

A random effect meta-analysis model was computed to estimate the pooled prevalence of cigarette smoking, and the variables associated with cigarette smoking were examined.

Results.

The meta-analysis of 13 studies showed that the pooled prevalence of current cigarette smoking was found to be 12.55% (95% CI: 10.39–14.72; I2 = 94.0%) with no publication bias according to Egger’s test (p=0.007) for cigarette smoking by 2.05 (95% CI: 1.52–2.75).

Factors associated with cigarette smoking were peer influence 2.79 (95% CI: 1.62–4.82; I2 = 35.7), khat chewing (95% CI: 2.81–15.26; I2 = 82.5), and alcohol use 11.16 (95% CI: 7.46–16.71).

Conclusion.

Our findings indicate a high prevalence of cigarette smoking among Ethiopian university students as compared to the general population.

Gender, peer influence, khat chewing, and current alcohol use were significantly associated with cigarette smoking.

The authors recommend promoting antismoking campaigns, emphasizing health hazard public service announcements about cigarettes, and integrating health education on smoking in youth-friendly services, especially targeting higher educational institutions.
