Residents' sense of acquisition and influencing factors in China's Sanitary City Initiative / 中华流行病学杂志

Objective: To analyze the residents' sense of acquisition (recognition, perceptibility and satisfaction) and influencing factors in China's Sanitary City Initiative. Methods: A cross-sectional survey was conducted from December 2020 to February 2021. The data about the residents' sense of acquisition were collected by using questionnaire from 2 465 residents who were aged ≥18 years and had lived in local communities for at least one year in 31, 14 and 16 cities with national sanitary city title in eastern, central and western China the influencing factors of residents' sense of acquisition in China's Sanitary City Initiative were analyzed by using multivariate multilevel model. Results: The total score of residents' sense of acquisition in China's Sanitary City Initiative was 231.15±32.45. After converting the scores according to the 100-score standardized method, the results showed that the recognition score, perception score and the satisfaction score were 85.02, 59.08 and 61.42, respectively. The results of influencing factors analysis showed that education level, gender, marital status, age, prevalence of physical exercise and self-assessment of health status were correlated with the scores of residents' recognition (β:1.24-2.54,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' perception (β:1.76-8.86,all P<0.05); the concentration of inhalable fine particles , the green coverage of built-up area, the level of GDP per capita and the type of residential community, education level, prevalence of physical exercise and self-assessment of health status were correlated with the score of residents' satisfaction (β:1.34-6.26,all P<0.05). Conclusions: The total score of residents' sense of acquisition in China's Sanitary City Initiative was relatively high, indicating that the policy has been widely recognized. The detailed management of policy implementation should be strengthened in the future, and more attention needs to be paid to actual needs of the residents to further improve the residents' sense of acquisition in China's Sanitary City Initiative.

Developing a Subjective Evaluation Scale for Assessing the Built Environments of China's Hygienic City Initiative / 生物医学与环境科学（英文）

Objective@#To develop a preliminary subjective evaluation scale for assessing the built environments of China's Hygienic City Initiative and to evaluate its reliability and validity.@*Methods@#The initial items of the scale were determined based on a review of policy documents and consultations with experts. The final items of the scale were confirmed through individual interviews with residents combined with the discretetrend method, critical ratio method, correlation coefficient method, and factor analysis method. Then, the dimensions of the scale were determined using exploratory factor analysis (EFA). The Cronbach's @*Results@#A scale containing five dimensions with 22 items was established, including urban lifestyle, governance, basic functions, environmental sanitation, and amenities. The Cronbach's @*Conclusion@#The preliminarily subjective evaluation scale for assessing the built environments of China's Hygienic City Initiative demonstrates a high level of reliability and validity. Additional empirical studies should be carried out to further verify the value of the scale in terms of practical application.

Cognition status and intervene needs for prevention of work-related musculoskeletal disorders among greenhouse farmers / 中国职业医学

OBJECTIVE: To explore the cognition status and intervene needs for prevention of work-related musculoskeletal disorders( WMSD) among greenhouse farmers. METHODS: By purpose sampling method,1 780 participants were surveyed by the Cognition Status and Intervene Needs for Prevention of WMSD Questionnaires. By convenience sampling and judgement sampling method,14 respondents were interviewed. RESULTS: 66. 0 %( 1 174 /1 780) of subjects surveyed thought that WMSD was one of the most serious occupational hazard. Only 20. 3 %( 362 /1 780) of subjects well understood the knowledge of preventing WMSD. 54. 7 %( 974 /1 780) of subjects considered that they will protect themselves according to requirement. A total of 96. 7 %( 1 721 /1 780) respondents were willing to attend training classes.With the improvement of culture level,the awareness rate of WMSD severity was decreased( P < 0. 01),the awareness rate of WMSD prevention knowledge was increased( P < 0. 05) and the more was willing to attend training( P < 0. 05).The awareness rate of WMSD severity in plant length of service ≥ 20. 0 years was higher than that of plant length of service < 20. 0 years( 68. 9 % vs 61. 5 %,P < 0. 05). The awareness rate of WMSD severity in WMSD patients was higher than that of non-WMSD person( 67. 2 % vs 61. 6 %,P < 0. 05). The most needs for the greenhouse farmers was health education intervention methods,power tools and protection of improvement and development. CONCLUSION: The knowledge of preventing musculoskeletal disorders is deficient among greenhouse farmers. Health education suitable for farmers 'lifestyle should be launched in greenhouse and it is essential to devise protective equipment.
