BackgroundAdolescent health risk behaviors are a public health priority given their prevalence and their associations with chronic diseases and life quality in adulthood. This study examined the heterogeneity of adolescent health risk behaviors and the associations between demographic characteristics and subgroup membership in rural western China.MethodsIn fall 2015, 2805 students from rural middle schools in Sichuan Province were surveyed using the Health-Related Behavior Questionnaire for Adolescents. Latent class analysis (LCA) was used to identify subgroups of adolescents with distinct patterns of health risk behaviors. Differences in class membership related to selected demographic characteristics were examined using multinomial logistic regression analysis.ResultsA four-class model emerged: (1) high-risk group (n = 108, 4.0%), (2) high-physical-inactivity and suicide-risk group (n = 340, 12.1%), (3) moderate-risk group (n = 897, 32.0%), and (4) low-risk group (n = 1460, 52.1%). The multinomial logistic regression analysis revealed that boys and adolescents with poor parental relationships and high allowances (spending money) were significantly more likely to be in the high-risk group than the low-risk group.ConclusionsAdolescents in rural western China are a heterogeneous population requiring different tailored and effective interventions.

PTSD symptoms among adolescent survivors of a catastrophic earthquake seemed to persist over time. Long-term interventions are needed to alleviate PTSD symptoms among adolescent survivors. (Disaster Med Public Health Preparedness. 2018;page 1 of 5).

To understand the current situation of occupational exposure to blood-borne pathogens in a women's and children's hospital and analyze the causes to provide a scientific basis for improving occupational exposure prevention and control measures. We analyzed occupational exposure to blood-borne pathogens in a third-class women's and children's hospital from 2015 to 2018, considering the workers’ occupational categories and length of service; the sites, types, and causes of exposure; and the pathogens of the source patients. From 2015 to 2018, there were 146 cases of occupational exposure to blood-borne pathogens, mainly from sharp-instrument injuries (81.5%; 119/146). Trainees represented the highest proportion of occupational exposure (30.1%; 44/146), followed by nurses (29.5%; 43/146). Occupational exposure among staff with less than one year of service accounted for 43.2% (63/146) of cases. Fisher's exact test showed that different occupational groups had different types of occupational exposure, and among the occupationally exposed populations, the proportion of sharp injuries is higher than that of blood and body fluid exposure, and the difference is statistically significant (χ2 = 12.937, P = 0.008). Different occupational groups faced exposure to different types of pathogens: medical staff were more likely than workmen to be exposed to hepatitis B, while workmen were more likely than medical staff to be exposed to unknown pathogens; these differences were statistically significant (χ2 = 55.344, P < 0.001). Health records were established for all cases of occupational exposure to blood-borne pathogens, and no staff members contracted a blood-borne disease due to occupational exposure. In order to reduce occupational exposure, regular training in occupational protection for junior medical staff and workers should be strengthened, the monitoring and protection system of occupational exposure to blood-borne pathogens improved, standard prevention measures strengthened, operations standardized, safe injection equipment provided, and comprehensive measures taken.

Background Few studies have explored the health and development of AIDS orphans using the positive youth development (PYD) framework. Grounded in this framework, the main objective of this study is to examine how internal assets (i.e., resilience) and external assets (i.e., school connectedness, peer support) affect subjective well-being among Yi AIDS orphans in the Liangshan Yi Autonomous Prefecture, Sichuan province, China. Methods A cross-sectional survey was conducted by interviewing 571 AIDS orphans and 979 non-orphans of Yi ethnic minority from 5th-10th grades. Structural equation models (SEM) were utilized to identify and estimate the direct and indirect effects of internal and external assets on subjective well-being. Results The average score of subjective well-being was significantly lower for AIDS orphans than for in non-orphans (P < 0.05). Resilience, school connectedness, peer support (number of friends, caring friends), and self-rated physical health had significant and positive direct effects on subjective well-being. In addition, the effects of school connectedness, and peer support on subjective well-being were mediated by resilience. Conclusions Positive individual and school-related contextual assets can bolster subjective well-being among AIDS orphans. The design of health intervention programs for AIDS orphans should incorporate these positive development assets.
