Quitting Smoking by Age 35 Years—A Goal for Reducing Mortality
Menée à partir des données d'une enquête américaine réalisée sur la période 1997-2018 auprès de 551 388 personnes (âge moyen : 48,9 ans ; 56 % de femmes), cette étude évalue l'effet des comportements tabagiques sur la mortalité en fonction du sexe et de l'origine ethnique
Thomson et al reported that there were almost 75 000 deaths by the end of 2019 among 551 338 respondents to the US National Health Interview Survey from 1997 to 2018. Their findings showed that cigarette smoking was associated with earlier death overall and increased mortality from cancer, heart disease, and lower respiratory disease. In their study, the excess mortality associated with smoking was higher among women than men. The study, to my knowledge, is the first to estimate risk of mortality associated with smoking among race and ethnicity subgroups of the US population. The authors found that compared with the non-Hispanic White population, Hispanic and non-Hispanic Black individuals had lower frequency and intensity of smoking and began smoking at older ages, although the mortality associated with smoking was still substantial. These results remind us that reducing smoking intensity (cigarettes per day) should be one of the goals for tobacco control programs.
