摘　　要：Background:Nicotine dependence,also known as tobacco dependence,is a common chronic disease and a major risk factor for chronic respiratory diseases.The present study was designed to determine the prevalence of nicotine dependence and its changes among smokers aged 40 years and older in China,to analyze the characteristics of nicotine dependence among smokers,and to provide a reference for smoking cessation interventions.Methods:The data were sourced from nationally representative large-sample surveys conducted during 2014-2015 and 2019-2020 in the Chinese population,covering 125 counties(districts)in 31 provinces,autonomous regions and municipalities.Variables related to smoking and nicotine dependence among residents≥40 years old were collected in face-to-face interviews.A total of 20,062 and 18,975 daily smokers were included in the 2014-2015 and 2019-2020 surveys,respectively.The severity of nicotine dependence was evaluated according to the Fagerström Test for Nicotine Dependence and Heaviness of Smoking Index.The level and change in nicotine dependence among daily smokers aged≥40 years were estimated using a complex weighted sampling design,and their influencing factors were analyzed.Results:Levels of nicotine dependence among daily smokers aged≥40 years in China could be divided into very low,low,medium,high,and very high,accounting for 31.1%,27.9%,13.4%,20.5%,and 7.1%of the total,respectively.The average Fagerström Test for Nicotine Dependence score was 3.9(95%confidence interval[CI]:3.8-4.0),with the prevalence of medium-high nicotine dependence being 41.0%(95%CI:39.0-42.9%)and that of high and very high nicotine dependence being 27.6%(95%CI:26.0-29.3%),both of which were significantly higher in men than in women(both P<0.001).Among daily smokers,those with a low education level,age at smoking initiation<18 years,and with smoking duration of≥20 years had a higher degree of nicotine dependence.In terms of geographic region,the level of medium-high nicotine dependence in South China was higher th
