[Survey on diarrhea symptoms and diarrhea vaccination willingness of residents in Tianjin].

<b>Objective:</b> To understand the symptoms of diarrhea of residents in Tianjin and their willingness to vaccinate, to provide reference for health education, prevention and control of infectious diarrhea. <b>Methods:</b> Cross-sectional study design was adopted. From September to December 2023, a questionnaire survey was conducted among some residents as subjects in Nankai District, Beichen District, Baodi District and Binhai Area of Tianjin by multistage stratified cluster random sampling,to collect information such as sociodemographic characteristics, diarrhea symptoms and vaccination intention. According to the formula <i>n</i>=[<i>u</i>²<i>_απ</i>(1 -<i>π</i>)]/<i>δ</i>², the estimated sample size was 3 458 cases. The logistic regression model was used to analyze the factors related to the willingness of the respondents to receive diarrhea vaccination. The software SPSS 24.0 was used for statistical analysis. <b>Results:</b> A total of 3 808 subjects were investigated, with the male-to-female ratio as 1∶1.11 (1 806∶2 002), the age was (42.48±21.59) years old, and the education level of middle school or below accounted for 50.84% (1 936/3 808). The incidence rate of diarrhea was 18.28% (696/3 808), and 48.84% (1 860/3 808) were willing to be vaccinated with diarrhea vaccine. The results of multivariate logistic regression analysis showed that the age was 15-59 years old and ≥60 years old (a<i>OR</i>=2.31, 95%<i>CI</i>:1.80-2.96; a<i>OR</i>=1.66, 95%<i>CI</i>:1.38-2.00), lived in Binhai Area (a<i>OR</i>=2.09, 95%<i>CI</i>:1.62-2.71), and those who knew that community health service centers can provide the vaccination (a<i>OR</i>=1.61,95%<i>CI</i>:1.34-1.92), those who walked from the address to the community health service center were less than 15 minutes (a<i>OR</i>=1.54, 95%<i>CI</i>:1.28-1.85), those who often travel or on business (a<i>OR</i>=1.36, 95%<i>CI</i>:1.07-1.73), and those who actively obtained health care information related to diarrhea prevention when going abroad (a<i>OR</i>=1.69,95%<i>CI</i>:1.43-1.98) were more willing to be vaccinated against diarrhea. <b>Conclusions:</b> The incidence of diarrhea symptoms of residents was slightly higher in Tianjin, but they were less willing to be vaccinated against diarrhea. People who often go outside and go abroad were more willing to be vaccinated against diarrhea. It is suggested that the popular science propaganda and health education of diarrhea vaccine should be effectively carried out by using network platform in community.
