To develop and test a model based on Bandura's social cognitive theory to predict healthy lifestyle behaviors for the prevention of osteoporosis.
Participants were 354 girls, ages 8-11 years, recruited from area Girl Scout troops. Baseline data from a randomized trial of behavioral interventions are presented. Measures of social support, knowledge, self-efficacy, dietary calcium intake, and weight-bearing physical activity (WBPA) were obtained via interviews and self-administered questionnaires.
A structural equation model was tested and fit the data well. Family social support, perceived self-efficacy for eating a calcium-rich diet, and knowledge of WBPA significantly predicted calcium intake. Friend and family support for exercise predicted WBPA. Self-efficacy partially mediated the relationship between family support and calcium intake, as confirmed by Holmbeck's post-hoc probing strategy (2002).
Suggestions are made for primary prevention interventions such as parent and peer involvement, health education, and problem-solving training.
基于班杜拉的社会认知理论开发并测试一个模型，以预测预防骨质疏松症的健康生活方式行为。
参与者为354名年龄在8至11岁的女孩，她们来自当地的女童军部队。呈现了一项行为干预随机试验的基线数据。通过访谈和自填问卷获取社会支持、知识、自我效能、膳食钙摄入量和负重体育活动（WBPA）的测量数据。
测试了一个结构方程模型，该模型与数据拟合良好。家庭社会支持、摄入富含钙饮食的自我效能感以及WBPA知识显著预测了钙摄入量。朋友和家庭对运动的支持预测了WBPA。如霍尔姆贝克（2002年）的事后探测策略所证实，自我效能部分介导了家庭支持与钙摄入量之间的关系。
针对初级预防干预提出了建议，如家长和同伴参与、健康教育和问题解决培训。
