To understand the current situation of adult tobacco prevalence in each sub-district and township of Dingzhou city, Hebei Province, provide data support for formulating grass-roots tobacco control policies, and provide a reference for estimating tobacco prevalence indicators at the county-district level.
A multi-stage stratified cluster sampling method and Probability Proportional to Size (PPS) sampling method were used to conduct a questionnaire survey among permanent residents aged 15 and above in Dingzhou city. The survey data were cleaned, weighted, and analyzed using SAS 9.4. The current smoking rate, quitting rate, and second-hand smoke exposure rate in Dingzhou city were reported. The Small Area Estimation (SAE) method was used to estimate the above-mentioned indicators for each sub-district and township.
A total of 7 660 valid questionnaires were collected in this survey, with an overall response rate of 68.70%. In 2023, the current smoking rate among people aged 15 and above in Dingzhou city was 22.27%, the quitting rate was 9.60%, and the second-hand smoke exposure rate among non-smokers was 36.84%. The estimation results of the SAE model showed that there were differences in tobacco prevalence monitoring indicators among different sub-districts and townships. Townships such as Xingyi Town, Liqinggu Town, and Dongliuchun Township in the southern part of Dingzhou city had relatively high current smoking rates (25%-35%). Some townships in the northwest and southeast regions had relatively low quitting rates (less than 10%), while the sub-districts and townships with relatively high second-hand smoke exposure rates were more scattered, with the rates in Dongting Town and Xizhong Town exceeding 50%.
The SAE model can be used to estimate tobacco prevalence monitoring indicators at the county-district and even sub-district and township levels. Currently, the tobacco prevalence situation in some sub-districts and townships of Dingzhou city is relatively severe. Targeted grass-roots tobacco control work should be carried out, the construction of smoke-free environments should be strengthened, and grass-roots smoking cessation services should be promoted.
