Regular physical activity is an important lifestyle behavior for preventing or reducing the burden of osteoporosis, and for promoting optimal bone health. This report evaluates the effect of an osteoporosis education program on knowledge, self-efficacy, and initiation and/maintenance of physical activity (PA) in older African Americans.
African American adults 50 years and older (n=130) were randomly assigned to either experimental (EG) or control (CG) groups. Immediately following baseline assessment EG was offered six-weekly education sessions, using the Expanded Heath Belief Model and the CG offered same after the intervention. Main outcome measures were knowledge and self-efficacy regarding osteoporosis and engagement in PA.
One hundred and ten (59=EG, 51=CG) participants completed all assessments. Overall, significantly higher (p<.01) mean self-efficacy and knowledge scores were observed in the EG than in the CG. Physical activity scores were positively related to self-efficacy but not knowledge scores.
Self-efficacy is important in increasing PA in older African Americans, and emphasis on culturally appropriate strategies may improve PA and reduce the risk of osteoporotic fracture.
规律的体育活动是预防或减轻骨质疏松症负担以及促进骨骼健康的重要生活方式行为。本报告评估了一项骨质疏松症教育计划对老年非裔美国人的知识、自我效能以及体育活动（PA）的启动和维持的影响。
50岁及以上的非裔美国成年人（n = 130）被随机分配到实验组（EG）或对照组（CG）。在基线评估后，立即为实验组提供为期六周的教育课程，采用扩展健康信念模型，对照组在干预后提供相同课程。主要结局指标是关于骨质疏松症的知识和自我效能以及参与体育活动的情况。
110名（59名在实验组，51名在对照组）参与者完成了所有评估。总体而言，实验组的平均自我效能和知识得分显著高于对照组（p <.01）。体育活动得分与自我效能呈正相关，但与知识得分无关。
自我效能在增加老年非裔美国人的体育活动方面很重要，强调适合文化背景的策略可能会改善体育活动并降低骨质疏松性骨折的风险。
