Status and social-ecological factors of interactive health literacy among adolescents in poverty-stricken areas of Yanbian / 中国学校卫生

Objective@#To understand the current situation of adolescents interactive health literacy in Yanbian poverty-stricken area and associated social-ecological factors, so as to provide scientific basis for targeted health education and policy adolescents in this area in the future.@*Methods@#Using cluster sampling method, a questionnaire survey was conducted on 818 junior high school students in grades 7 and 8 of all 4 junior high schools in Antu County in November 2019.@*Results@#The scores of interaction health literacy was in moderate level (101.38±20.12) in Yanbian poverty-stricken area. The average scores of all dimensions was (3.62±0.96), stress management (3.35±1.08), interpersonal relationship (3.29±0.82), nutrition (3.21±1.02), health awareness (2.99±0.82), physical activity (2.68±0.85). The results of multiple linear regression analysis showed that grade, gender, BMI, perceived health care, perceived academic performance, participation in extracurricular activities, types of guardians, parenting style; perceived school health policy; average screen time were associated with the level of adolescent interactive health literacy (P<0.05), explaining 54.5% of the total variation(F=35.97，P<0.01).@*Conclusion@#The health literacy level of adolescents in poverty-stricken areas is affected by personal, family environment, interpersonal relationship, school, media and other factors. It is recommended that future health literacy interventions for adolescents should consider the students themselves, as well as their socio-ecological environment.

[Microclimate and comfortable degree of Shanghai urban open spaces in summer].

Based on the observation data of air temperature, relative humidity, wind speed, and solar radiation from May to August 2006, the regulation effects of five types of open spaces (square, fountain, grassplot, corridor, and woodland) in Shanghai urban districts on the microclimate were analyzed, and discomfort index (DI) was introduced to evaluate the effects of these five types of open spaces on human body' s comfortable degree. The results showed that there existed definite differences in the air temperature and relative humidity among the open spaces, with the mean temperature decreased in the order of square > grassplot > fountain > corridor > woodland, and the mean relative humidity decreased in the order of woodland > corridor > fountain > grassplot > square. The area of the square, the wind speed and direction near the fountain, the grass species on the grass-plot, the width and tree coverage of the corridor, and the tree coverage and canopy height of the woodland had significant correlations with the microclimate parameters of corresponding open spaces. Comparing with other three types of open spaces, woodland and corridor had better regulation effects on the microclimate via shading, decreasing air temperature, and increasing relative humidity.
