Tobacco Smoking-Attributable Mortality in Kenya: 2012 – 2021

Résumé fourni par la source

BACKGROUND: Tobacco smoking poses a significant risk for various diseases, including cardiovascular diseases, chronic respiratory diseases, and cancers. In Kenya, tobacco-related deaths contribute substantially to non-communicable disease mortality. This study aims to quantify the mortality attributed to tobacco smoking in Kenya from 2012 to 2021. METHODS: Employing a prevalence-based analysis model, the study utilized Population Attributable Fraction to estimate age-specific Smoke Attributable Mortality (SAM) rates for individuals aged 35 years and older. Causes of death associated with tobacco use, including cancers, cardiovascular diseases, respiratory diseases, tuberculosis, and diabetes, were analyzed based on age, sex, and death records between 2012 and 2021. RESULTS: Over the study period, 60,228 deaths were attributed to tobacco-related diseases, with an annual increase observed until 2016 and subsequent fluctuations. Respiratory diseases, diabetes mellitus, malignant cancers, tuberculosis, and cardiovascular diseases collectively accounted for 16.5% of deaths among individuals aged 35 and older. Notable contributors were pneumonia and influenza (respiratory diseases), oesophageal cancer (cancers), and cerebrovascular diseases (cardiovascular diseases). SMOKING PREVALENCE: Smoking prevalence in Kenya indicated 17.4% of men, 0.9% of women, and 9% overall as current smokers. Former smokers constituted 10.6% of men, 1.4% of women, and 5.9% overall. SMOKING-ATTRIBUTABLE MORTALITY: Out of observed deaths, 16.5% were attributed to smoking, with respiratory diseases (40.5%), malignant cancers (31.4%), tuberculosis (13%), cardiovascular diseases (8.9%), and diabetes mellitus (6.1%) contributing. Pneumonia and influenza, oesophageal cancer, chronic airway obstruction, and tuberculosis were primary causes, comprising 70% of all Smoking-Attributable Mortality (SAM). DISCUSSION: The study underscores smoking's substantial impact on mortality in Kenya, emphasizing the urgency of preventive measures and tobacco control strategies. The findings highlight the differential contributions of smoking to various diseases, indicating the need for targeted interventions tailored to specific health outcomes. CONCLUSION: Tobacco-related mortality is a significant public health concern in Kenya. Efforts should focus on preventing tobacco use and managing associated disease burdens. Smoking cessation initiatives and comprehensive tobacco control measures are imperative to mitigate the impact on population health.
