ABSTRACT BACKGROUND: Osteoporosis, characterized by decreased bone density and increased fracture risk, imposes significant physical, psychosocial, and financial burdens. Early detection and prevention are crucial for managing osteoporosis and reducing the risk of fractures. OBJECTIVES: To investigate the relationship between Hepatitis A seropositivity and bone mineral density (BMD) in adolescents and adults and to explore the potential link between Hepatitis A infection and osteoporosis risk. DESIGN AND SETTING: This cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 to evaluate the association between hepatitis A seropositivity and BMD in 15,693 participants. METHODS: Multivariable regression analysis was used to calculate the mean BMD and standard error for adolescents and adults, followed by an independent z-test to determine whether there was a significant difference between the seropositive and seronegative groups. RESULTS: Hepatitis A seropositive adolescents and adults had lower BMD than their seronegative counterparts, with significant differences in lumber spine (mean difference = -0.03 g/cm2, P < 0.01 for both age groups) and pelvis BMDs (mean difference = -0.02 g/cm2, P < 0.01 for the adult age groups), after adjusting for various covariates. CONCLUSIONS: This study confirmed that both adolescent and adult individuals seropositive for Hepatitis A antibodies had reduced BMD among both adolescents and adults, especially in the adult group. This finding suggests a possible link between Hepatitis A infection and risk of osteoporosis.

Objective@#To explore the effectiveness of painting group counseling intervention on problem behavior and the quality of parent child relationship in primary school students.@*Methods@#The problem behaviors of grade fouth primary school students were screened and compared with the norm. Two classes were randomly selected as the intervention group and control group, respectively. Intervention group received for an 8 week painting group counseling experiment. Conners Child Behavior Rating Scale, Problem Solving Scale and Parental Acceptance Questionnaire were used as the evaluation tools.@*Results@#There was no significant difference in the detection rate of problem behavior between the experimental and the control group before intervention(27.59%, 15.38 %, Z=1.10, P >0.05). After intervention, the detection rate of problem behavior in the experimental group was significantly lower than that in the control group(17.24%, 3.85%, Z=3.71, P <0.01). There was no difference in the scores of problem solving and parental acceptance between the two groups before the intervention( t=0.63, 0.38, P >0.05). After the intervention, the score of problem solving in the experimental group was lower than that in the control group( t=-2.28, P <0.05), and the score of parental acceptance was higher than that in the control group( t=2.57, P <0.05). For the intervention group, problem behavior and problem solving decreased significantly( t=2.56, 2.44, P <0.05), while the scores of parental acceptance increased significantly( t=-2.26, P <0.05)after the intervention. The scores of these three variables in the control group showed no significant changes before and after the intervention( P >0.05). The results of repeated measurement variance showed that the main effect of problem behavior and the interactive effect of problem solving and parental acceptance( F=8.63, 8.01, 4.62, P <0.05) were significant.@*Conclusion@#Painting group counseling can reduce the problem behaviors of primary school students and improve the quality of parent child relationship. It can be applied in primary school mental health education and plays a positive role in promoting the healthy development of primary school students.

Abstract@#The visual health of children and adolescents in China has become a major issue that is relevant to the nation s present and its future. This article analyzed the value of map reading and searching for specific features during orienteering projects for myopia prevention and control. The findings suggest that orienteering exercises show good regulatory effects on eye muscles, effectively improve concentration, and help to stimulate mental activity and visual system. Targeted exercises, including scanning maps for specific features, is beneficial for myopia prevention and control. It is proposed that, by changing the teaching style of cross-country orienteering, teaching space, and teaching scene, exercises can be tailored to treat and relieve eye strain, as well as to prevent and control myopia, which is essential to promote the visual health of children and adolescents.
