[Prevalence and factors associated with smoking among adults living in the Moungali district of Brazzaville in 2021].

Introduction: tobacco epidemic is a real public health problem in the world and in Africa. The purpose of this study was to estimate the prevalence and identify factors associated with smoking among adults living in the Moungali district.

Methods: we conducted a cross-sectional analytical study of 800 adults. Two-stage random sampling was used to select subjects in the Moungali district, Brazzaville, in September 2021. Binary logistic regression using the ascending stepwise method allowed identification of the associated factors. The adjustment of the model was verified by the Hosmer Lomeshow test. Data were collected via the Kobo collect V1.30.1 app. and analyzed with the Stata 15.0 software.

Results: smoking prevalence was 4.63%, 95% CI [3.37-6.31]. Males (AOR=8.36 95% CI [3.74-18.72], p-value < 0.0001), alcohol consumption (AOR=2.6 95% CI [1.11-6.11], p-value = 0.028), and professional activity (formal or informal sector) (AOR=3.91 95% CI [1.16-13.11], p-value = 0.027) were factors significantly associated with smoking.

Conclusion: this study highlights that smoking is a stronger risk factor in men than in women. In addition, alcohol consumption and professional activity in the formal or informal sector are also factors associated with active smoking. Preventive actions focusing on these factors are necessary to effectively fight smoking in adults.
