Tobacco-alcohol consumption, socio-sanitary profile and factors influencing the anthropometric and cardiorespiratory parameters of Kinshasa smokers

Objective: To determine the prevalence of alcoholism and the influence of the associated «tobacco-alcohol» consumption on the anthropometric and cardiorespiratory parameters of some smokers in Kinshasa. Material and Method: Cross-sectional and prospective study, conducted in Kinshasa from January to October 2017, including 120 tobacco smokers with at least 5 years of service, with a mean age of 36 ± 9 years. The Global Tobacco Surveillance System (GTSS) Validated Adult Tobacco Surveillance Questionnaire has been adapted and used. Socio-demographic, anthropometric, cardiorespiratory parameters and behavioral of consumption were the variables of interest. At the p≤0.05 threshold, correlation and multiple linear regressions allowed for statistical inference. Results: The sex ratio was 19/1 (M / F), 84.2% of the smokers were alcoholics. The median seniority in smoking and alcohol consumption was 8 years. The median amount of tobacco consumed was 27 pack-years; it was positively correlated with the amount of alcohol consumed, the oldest in smoking and alcoholism. The BMI of smokers was influenced by seniority in smoking and the amount of alcohol consumed (R2 = 0.049, p <0.001). RR rest was influenced by the amount smoked, seniority in tobacco and alcohol (R2 = 0.187, p <0.001). While the DBP was influenced by age, the amount of smoked tobacco, alcohol consumed as well as seniority in smoking and alcoholism (R2 = 0.102, p <0.001). Conclusion: The prevalence of alcoholism is very high in Kinshasa smokers; this association "tobacco-alcohol" has an influence on their BMI, RR rest and DBP.
