Abstract:
Objective: To understand the prevalence of smoking and its change in adults aged ≥40 years in China and provide evidence for the development of chronic obstructive pulmonary disease (COPD) prevention and control strategies. Methods: The data of this study were obtained from COPD surveillance in China during 2014-2015 and during 2019-2020. The surveillance covered 31 provinces (autonomous regions and municipalities). A multi-stage stratified cluster random sampling were used to select residents aged ≥40 years, and face-to-face interviews were conducted to collect the information about their tobacco use. After complex sampling weighting of the samples, the current smoking rate, average age to start smoking and average daily cigarette consumption of people with different characteristics during 2019-2020 were estimated, and the changes in the current smoking rate and average daily cigarette consumption were analyzed from 2014-2015 to 2019-2020. Results: During 2019-2020, the current smoking rate in adults aged ≥40 years was 27.2%, and the rate was much higher in men (52.1%) than in women (2.5%).The average age of the smokers to start smoking was 20.0 years old, and men usually started smoking at younger age (19.6 years) compared with women (27.9 years). The average daily cigarette consumption of daily smokers was 18.0 sticks, and the consumption of men (18.3 cigarettes) was higher than that of women (11.1 cigarettes). Compared with the surveillance results during 2014-2015, the current smoking rate had decreased by 2.8 percentage points in the general population, 4.1 percentage points in males, 1.6 percentage points in females, and the urban and rural areas fell by 3.1 percentage points and 2.5 percentage points, respectively. The average daily cigarette consumption decreased by 0.6 sticks. Conclusions: In recent years, the current smoking rate and average daily cigarette consumption in adults aged ≥40 years decreased in China, but smoking is still common in more than quarter of this population and more than half of men aged ≥40 years. It is necessary to take targeted tobacco control measures based on population and regional characteristics to further reduce the smoking level of the population.
