Mortality risk ratios comparing smokers with nonsmokers were adjusted for age, educational level, and use of alcohol. Results : About 5% of female control subjects and 37% of male control subjects between the ages of 30 and 69 years were smokers. In this age group, smoking was associated with an increased risk of death from any medical cause among both women (risk ratio, 2.0 99% confidence interval [CI], 1.8 to 2.3) and men (risk ratio, 1.7 99% CI, 1.6 to 1.8). Daily smoking of even a small amount of tobacco was associated with increased mortality. Excess deaths among smokers, as compared with nonsmokers, were chiefly from tuberculosis among both women (risk ratio, 3.0 99% CI, 2.4 to 3.9) and men (risk ratio, 2.3 99% CI, 2.1 to 2.6) and from respiratory, vascular, or neoplastic disease. Smoking was associated with a reduction in median survival of 8 years for women (99% CI, 5 to 11) and 6 years for men (99% CI, 5 to 7). If these associations are mainly causal, smoking in persons between the ages of 30 and 69 years is responsible for about 1 in 20 deaths of women and 1 in 5 deaths of men. In 2010, smoking will cause about 930,000 adult deaths in India of the dead, about 70% (90,000 women and 580,000 men) will be between the ages of 30 and 69 years. Because of population growth, the absolute number of deaths in this age group is rising by about 3% per year.  Conclusions Smoking causes a large and growing number of premature deaths in India.

Public Titre : Smoking cessation and short- and longer-term mortality Type de document : document électronique Auteurs : Eo Rin Cho, Auteur ; Ilene K. Brill, Auteur ; Inger T Gram, Auteur ; Patrick E Brown, Auteur ; Jha Prabhat, Auteur Année de publication : 2024 Importance : 3 p. Langues : Anglais (eng) Catégories : [TABAC] étude:méta-analyse [TABAC] étude:statistique:mortalité [TABAC] sevrage tabagique Index. décimale : TA 3.2.1 Mortalité Résumé : BACKGROUND Smoking cessation reduces mortality and morbidity. However, the extent and rapidity at which cessation reduces contemporary death rates from smoking-related illnesses remain uncertain. METHODS We pooled current or former versus never cigarette smoker hazard ratios from four national cohorts with linkage to death registries in the United States, United Kingdom, Norway, and Canada among adults 20 to 79 years of age from 1974 to 2018. We calculated excess risk differences and survival, comparing current or never smokers with age-specific cessation and cessation fewer than 3, 3 to 9, or 10 or more years earlier. RESULTS Among 1.48 million adults followed for 15 years, 122,697 deaths occurred. Adjusting for age, education, alcohol use, and obesity, current smokers had higher hazard ratios for death compared with never smokers En ligne : https://evidence.nejm.org/doi/full/10.1056/EVIDoa2300272 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10222
