Abstract Improving health literacy can effectively reduce the risk of health risk behaviors and adverse health outcomes in children and adolescents. Global research on health literacy of children and adolescents has been increasing in recent years. The paper reviews the existing research and proposes that there is no universal definition and connotation of health literacy for children and adolescents, most of the studies use or make some revisions on the definition of adult health literacy in child and adolescent health literacy, failing to consider developmental characteristics and unique health needs of children and adolescents. Moreover, the assessment index system and instruments are diversified, making the research findings from different studies difficult to compare, and to obtain consistent and reliable conclusions. Future endeavors are encoouraged to expand health literacy researches and to update more comprehensive and practical definition, and to develop a standardized assessment instrument that can be validated in Chinese culture.

Objective: To preliminarily develop the Infectious Disease Prevention Health Literacy Scale for Chinese Middle School Students, as an important measuring tool for assessment of comprehensive abilities in infectious disease prevention of Chinese middle school students. Methods: The basic dimensional framework and item pool were established by literature review in the view of public health. Then Delphi method was used to modify the framework and item pool to scale 1.0. Panel discussion in middle school students was used to adjust the expression and structure of scale 1.0, turning it into scale 2.0. With the confirmation of theory experts subjects, the scale was preliminarily developed. Results: Literature review suggested that the basic dimension framework included five longitudinal dimensions and seven horizontal dimensions. According to Delphi method ( n =18), the Kendall s coefficient of concordance ( W ) of the scale was equal to 0.14 ( P <0.01), the average importance, proportion of full marks, coefficient of variation and weight coefficient of all dimensions and items met the inclusion criteria. According to panel discussion, the scale was finally adjusted into scale 2.0 with 53 items. Conclusion This study preliminarily established the Infectious Disease Prevention Health Literacy Scale for Chinese Middle School Students, which might be applied in both scientific research and practical use.

Objective: To understand the current situation regarding sex education in home and school settings in China, and to provide a scientific basis for more effective family and school sex education. Methods: Using a convenient sampling method, a crosssectional survey of students from grade 7 to grade 9 in Beijing, Liaoning, Sichuan, Chongqing, Yunnan and Henan was carried out from September to December 2021. The questionnaire covered general demographic information, sex education at home and school, and the status of comprehensive sexuality education. Finally, 4 109 valid questionnaires were collected. Results: A total of 760(18.50%) middle school students had not received any form of sex education, 923(22.46%) had only received sex education at school, 299(7.28%) had only received sex education at home, and 2 127 (51.76%) had received sex education at home and at school. The scores related to junior middle school students knowledge of comprehensive sexuality education was (12.43±2.89) points, the attitude score was (47.86±5.31) points, the behavior score was (40.44±5.18) points, and the comprehensive level score was (82.02±9.01) points. Junior middle school students who received sex education at home and in school had the highest comprehensive level of sex education( P <0.01). Junior middle school students who only received sex education at school had a higher comprehensive sexuality education knowledge level than those who only received sex education at home( P < 0.01 ). The level of comprehensive sexuality education behavior among junior middle school students who only received family sex education was significantly higher than among those who only received sex education at school( P <0.01). Conclusion Receiving sex education in both home and school settings can effectively improve the comprehensive sexuality education competency among junior middle school students. School based sex education should be further implemented in the future and family sex education should be encouraged.

Abstract Subjective social status and life skill level are important influencing factors of adolescent health risk behaviors, and they interact with each other and jointly act on adolescent health risk behaviors, which make the mechanism of adolescent health risk behaviors become more diverse and complex. The current paper reviews the correlations among subjective social status, life skill level and adolescent health risk behaviors, in order to explore the joint influence of subjective social status and life skill level on adolescent health risk behaviors, then provides future directions for exploring possible mechanisms, and proposes recommendations for effective prevention strategies of adolescent health risk behaviors.
