Prevalence and factors associated with smoking among patients with tuberculosis in Conakry (Guinea)

Abstract

Introduction: Smoking increases the risk of Mycobacterium tuberculosis infection and the risk of tuberculosis disease progression in infected individuals. The objective of this study was to estimate the prevalence and factors associated with tobacco use among tuberculosis patients.

Methodology: We conducted a 3-month cross-sectional study with analytical aims in tuberculosis treatment centers in Conakry. 646 patients were included in this study, in whom smoking status and tobacco consumption in the last 12 months were assessed. We used the Fargerstrom test to measure nicotine dependence. The backward stepwise multivariate logistic regression model was used to identify potential factors associated with smoking in tuberculosis patients. The significance threshold was set at 5%.

Result: The prevalence of smoking was 37%, the mean age was 37.84±43.24, the male sex was predominant M/F=1.74; In 44.89%, these patients were illiterate; more than 14% were co-infected TB/HIV and 23.10% were alcoholics. Only 35.4% had knowledge of the health risks associated with smoking. The factors potentially associated with smoking were: age (p<0.001); male sex predominantly0.03 [0.01;0.06]; low level of education5.53 [2.62;12.6]. Low-income patients 2.06 [1.16;3.65]. Tuberculosis smokers were statistically associated with alcoholism 0.05 [0.03;0.08].

Conclusion: the prevalence of tobacco-dependent tuberculosis patients remains high and iThere appears to be sufficient evidence to conclude that factors such as alcohol consumption, gender, age, and standard of living were significantly associated with smoking.
