Objective : Objective To investigate the demand for health management and influencing factors among occupational population at high risk of stroke, so as to provide insights into the development of stroke health management strategies among occupational population. Methods: Occupational population aged 40 to 60 years who participated in health examination were sampled from three tertiary hospitals in Luzhou City, Sichuan Province using a quota sampling method in the ratio of 4∶1∶1, from August to December 2020. Participants' blood biochemistry tests and health examination were collected through the examination reports, and the participants at high risk of stroke were screened using the assessment criteria for high-risk of stroke. Participants' general information and demand for health management were collected using questionnaire surveys. In addition, factors affecting the demand for health management were identified using a multivariable logistic regression model. Results: A total of 3 003 people who participated in health examination were investigated, and 1 062 participants met the assessment criteria for high risk of stroke, accounting for 35.36%. There were 1 000 men (94.16%) and 62 women (5.84%), with a mean age of (49.26±4.97) years. There were 414 professional and technical staff (39.50%). There were 709 participants (66.76%) with demand for health management, with the top three in the demand as health checkups (915 participants, accounting for 86.16%), health consultation (601 participants, accounting for 56.60%) and exercise guidance (560 participants, accounting for 52.73%), and 210 participants (19.77%) received health management. Multivariable logistic regression analysis showed that occupational population at high risk of stroke who received health management were more likely to have the demand for health management (OR=2.158, 95%CI: 1.479-3.149). Conclusions The occupational population at high risk of stroke have the demand for health management. Having received health management may affect the demand for health management among occupational population at high risk of stroke.

Objective: To investigate the implementation of sex education and its influencing factors among preschool teachers in Luzhou City, Sichuan Province, so as to provide insights into promoting the development of sex education, physical and mental health for preschool children. Methods: In January 2022, preschool teachers were sampled in 24 kindergartens in Longmatan District, Naxi District and Hejiang County of Luzhou City using the stratified random cluster sampling method. Demographic information, knowledge, attitudes, implementation of sex education, as well as difficulties, support, and needs in implementing sex education among preschool teachers were collected through questionnaire surveys. Factors affecting practice of sex education by preschool teachers were analyzed using a multivariable logistic regression model. Results: A total of 461 preschool teachers were included, including 456 females (98.92%), and had a median age of 28.00 (interquartile range, 9.50) years. The proportions of preschool teachers with good and pass of knowledge about sex education for preschool children were 10.20% and 57.48%, respectively. The proportions of preschool teachers with positive and general attitudes towards sex education were 28.20% and 36.44%, respectively. A total of 343 preschool teachers had implemented sex education (74.40%). A lack of a relaxed social environment was the main difficulty in carrying out sex education for preschool children (76.14%), while support from parents of preschool children was the primary need for conducting sex education activities (75.27%). Multivariable logistic regression analysis showed that age (>30 years, OR=2.218, 95%CI: 1.256-3.917), kindergarten type (public, OR=2.101, 95%CI: 1.253-3.524), attitude towards sex education (positive, OR=2.083, 95%CI: 1.036-4.187), participation in activities related to sex education (OR=6.355, 95%CI: 3.362-12.015), and communication with parents about sex education (OR=5.399, 95%CI: 3.152-9.248) were influencing factors for practice of sex education by preschool teachers. Conclusions The main difficulty in the practice of sex education for preschool children by preschool teachers in Luzhou City is a lack of a relaxed social environment, and there is a high demand for support from parents. Age, kindergarten type, attitude towards sex education, participation in activities related to sex education, and communication with parents about sex education are associated factors.

Objective: To evaluate the effectiveness of sex education curriculum on sex related knowledge, attitude and practice of preschool children in senior class, so as to provide a reference basis for the comprehensive development of early childhood sex education in the future. Methods: From December 2021 to July 2022, the two stage stratified sampling method was used to select 12 kindergartens in Luzhou City, of which 6 senior classes were chosen as the intervention group (360 before the intervention, 354 after the intervention), and the other 6 senior classes as the control group (416 before the intervention, 326 after the intervention). The intervention group was conducted with early childhood sex education classes in the form of a series of courses, with a total of four topics including one parent course and three child courses every month, while the control group received routine teaching schedule. A survey was conducted on the knowledge, attitude and practice of early childhood sex education among preschool children and their parents before and after the intervention. χ 2 text analysis was used to carry out the effect. Results: There was no statistically significant difference in sexual education related knowledge, attitude and practice between the intervention group and the control group before intervention ( P >0.05). There were statistically significant differences in the awareness rate of sexual knowledge (77.4%, 69.6%), positive attitude rate (73.7%, 10.1%), good practice rate (59.3%, 38.0%), and good knowledge, attitude and practice rate (37.9%,1.8%) between the intervention group and the control group after intervention ( χ 2=5.28, 279.77, 30.77, 134.62, P <0.05). Similar findings were observed in the intervention group before and after the intervention ( χ 2=63.39, 344.31 , 41.41, 161.03, P <0.05). The difference in the awareness rate of sexual related knowledge between the control group before and after intervention was statistically significant ( χ 2=44.29, P <0.05). Conclusion The early childhood sex education curriculum might help improve sex related knowledge, attitude and practice. Kindergartens should be encouraged to actively promote sex education, training, and guidance for preschool children and their parents, in order to improve the sex related knowledge, attitude and practice.

Objective To develop the knowledge,attitude,and practice evaluation scale for teach-ers'early childhood sex education and analyze the reliability and validity of the scale,providing evaluation tools for the research on teachers'early childhood sex education.Methods On the basis of relevant guidelines,pub-lications,and the theory of knowledge,attitude,and practice,a preliminary pool of items for the scale was formed by group discussions.The scale was drafted after two rounds of Delphi expert consultation.In May 2023,stratified cluster sampling was conducted,and 535 preschool teachers from Changshou District,Chongqing were selected for a survey.Cronbach's α coefficient,split-half reliability,exploratory factor analysis,and content validity were adopted to assess the reliability and validity of the scale.Results An evaluation scale for teachers'early childhood sex education was formulated,involving 27 items in 3 dimensions of knowledge,attitude,and practice.The total Cronbach's α coefficient of the scale was 0.875,and that of the knowledge,attitude,and practice dimensions were 0.902,0.743,and 0.879,respectively.The total split-half reliability of the scale was 0.937,and that of the knowledge,attitude,and practice dimensions were 0.934,0.821,and 0.912,re-spectively.The content validity of the scale was good,with a factor loading range of 0.500-0.836 and a cumu-lative variance contribution rate of 61.57.The average score of teachers'knowledge,attitude,and practice in sex education was 72.85±7.13,with a good rate of 70.84％.Conclusions The developed scale for evaluating teacher's early childhood sex education demonstrates good reliability and validity,and it can be used to evaluate the teachers'knowledge,attitude,and practice in early childhood sex education.The evaluation results indicate that teachers have low levels of knowledge,attitude,and practice in sex education,and relevant departments need to carry out training on the sex education for young children.

Objective To understand the current situation and influencing factors of kindergarten teach-ers'participation in training for preschool sex education in Luzhou city,and provide a basis for improving the sex education literacy of kindergarten teachers in the future.Methods A multi-stage stratified cluster sampling meth-od was adopted,and a questionnaire survey was conducted from December 2021 to January 2022 on the knowl-edge,attitude,and practice of preschool sex education among all the teachers in 24 kindergartens in Luzhou city.Results Among the 461 teachers,43.0％had participated in lectures/courses/training activities related to pre-school sex education;99.1％hoped to participate in lectures/courses/training activities related to preschool sex education;82.6％learned about child sexual knowledge through school education;75.5％expressed the hope to learn about child sexual knowledge through expert training.The results of multivariate Logistic regression showed that except private kindergartens as an inhibiting factor(OR=0.57,95％CI=0.37-0.87,P=0.008),high monthly income(OR=3.52,95％CI=1.13-9.30,P=0.011),more ways to know about sex education knowledge(OR=2.87,95％CI=1.76-4.70,P＜0.001),and social support(OR=1.58,95％CI=1.04-2.38,P=0.030)were promoting factors for teachers to participate in the training for preschool sex educa-tion.Conclusions The kindergarten teachers presented a participation rate but a high demand for the training for preschool sex education.They mainly obtain the sex education knowledge from school education.The nature of kindergarten,monthly income of teachers,social support situation,and ways of understanding sex education knowledge are the key factors influencing the teachers'participation in the training for preschool sex education.
