RESUMO
Objective@#To analyze the effect of the peer education intervention model on improving adolescent knowledge, attitudes, and behavior among primary and secondary school students, so as to provide a basis for exploring adolescent based health education methods.@*Methods@#A group of students from grades 4-5 and 7-8 were selected from two primary schools and two middle schools in a district of Chongqing. The sample was divided into an intervention group (n=685) and a control group (n=821), and the intervention group received peer education for one year. Basic information related to the pre and post intervention, and data regarding knowledge, attitudes, and behavior were investigated using a basic situation questionnaire and an adolescent knowledge attitudes behavior questionnaire that were designed by the research group.@*Results@#The results obtained after the intervention showed that the scores of adolescent knowledge attitudes behavior and the total scores of the intervention group increased from (10.00±6.39) (39.19±5.79) (28.69±4.24) and (77.89±12.66) to (15.65±5.87) (42.06±5.95) (29.95±4.05) and (87.66±12.93), and the difference was statistically significant (P<0.01). After the intervention, increasing of adolescent knowledge attitudes behavior and the total scores of the intervention group were (5.64±5.61) (2.87±6.72) (1.26±4.55) (9.77±11.91), respectively, which were higher than those of the control group [(4.42±5.15) (2.08±5.84) (0.86±4.24) (7.36±10.70)]. Except for adolescent behavior, increasing of other scores were statistically significant (t=-4.39,-2.40,-1.73,-4.09,P<0.05).@*Conclusion@#Peer education shows certain effects on improving adolescent knowledge and positive attitudes, although similar effect on adolescent behavior needs further study.
RESUMO
Objective@#To understand the health literacy level and its influencing factors among middle school students in Chongqing, and to provide a basis for health promotion.@*Methods@#Using stratified cluster random sampling and a self-designed questionnaire, we conducted a survey among 8 449 junior and senior high school students from four districts and counties in Chongqing municipality from November to December 2019.@*Results@#The attainment rates of total health literacy, functional health literacy, interactive health literacy, and critical health literacy among middle school students in Chongqing were 67.96%, 75.12%, 50.24%, and 72.21%, respectively. Among the 12 factors, low rates were observed in health decision-making, reasonable nutrition, and communication (41.52%, 46.09% and 62.18%, respectively). After controlling for related confounding factors, the results of the multivariate Logistic regression analysis indicated that the following factors affected the total health literacy of middle school students: the investigated region (OR=1.20); school segment (OR=1.35); relationship with mother (OR=1.52); relationship with teacher (OR=2.20); number of close friends (OR=1.68); and health education course (OR=1.52) (P<0.05).@*Conclusion@#The health literacy level of middle school students in Chongqing is relatively low. Therefore, it is necessary to focus on improving interactive health literacy in order to promote the healthy development of middle school students.
