目的：背景：身体活动是一种复杂的行为
这涉及到个人、社会、文化等多层次因素的相互作用，
环境水平。然而，以前的研究主要集中在
心理和/或社会环境因素以及
这些因素对身体活动的影响。很少有研究探讨
多层次因素可以相互作用以影响活动水平。因此
本研究的目的是检查直接和间接的影响，
影响日本青少年学校体育活动的多层次因素
小伙子们方法：在日本青少年的横断面调查中，
生活方式，379名初中男生受邀完成自我报告
年龄、年级、体重、身高、自我效能、社会支持（家庭，
朋友和老师），学校的物理环境（设备，设施和
安全）和每周午餐时间的平均体力活动分钟数
和放学后在学校发生的事情。结构方程模型
控制年龄的分析被用来检查身体的影响，
体质指数、自我效能感、社会支持和学校物理环境
午餐时间和课后体育活动的变量。结果：在
午餐时间、自我效能感对身体素质有直接的正向影响
活动BMI、设施和安全性与
通过自我效能感进行午餐时间的体力活动。均无
设备和社会支持与午餐时间身体检查的显著关系
活动在课后时间，家庭支持和设施直接
影响身体活动。自我效能感与
通过家庭支持进行体育活动。BMI、设备和安全间接
通过自我效能和/或家庭支持影响身体活动。
结论：影响青少年体力活动的因素是多层次的
男孩的情况不同，这意味着干预措施，
促进体育活动应该根据具体情况而定。调查结果鼓励
制定未来有效的干预措施，以促进身体活动
通过午餐时间的自我效能以及家庭支持，
放学后
Purpose: Background: Physical activity is a complex behavior
which involves the interaction of multilevel factors at the individual, social
and environmental level. However, previous studies have largely focused on
psychological and/or social environmental factors and the direct impact of
such factors on physical activity. There are few studies having examined how
multilevel factors may interact to influence activity level. Therefore, the
purpose of the present study was to examine both direct and indirect effects of
multilevel factors on school-based physical activity in Japanese adolescent
boys. Methods: In this cross-sectional survey of the Japanese adolescent
lifestyles, 379 junior high school boys were invited to complete self-report
measures of age, grade, weight, height, self-efficacy, social support (family,
friends and teachers), school physical environment (equipment, facilities and
safety) and average minutes per week of physical activity during lunch time
and after-school hours occurring at school. Structural equation modeling
analyses controlling for age were utilized to examine the effects of body
mass index (BMI), self-efficacy, social support and school physical environmental
variables on lunchtime and after-school physical activity. Results: During
lunch time, self-efficacy exhibited direct positive effects on physical
activity. BMI, facilities, and safety were indirectly associated with
lunchtime physical activity through self-efficacy. However, there were no
significant relationships of equipment and social support with lunchtime physical
activity. During after-school hours, family support and facilities directly
affected physical activity. Self-efficacy was indirectly related with
physical activity through family support. BMI, equipment, and safety indirectly
affected physical activity through self-efficacy and/or family support.
Conclusion: Effects of multilevel factor on physical activity among adolescent
boys differed according to context, which implies that interventions to
promote physical activity should be context-specific. Findings encourage
the development of future effective interventions to promote physical activity
through self-efficacy during lunch time as well as family support during
after-school hours.
