PURPOSE
To examine the effect of bone mineral density (BMD) screening via dual-energy x-ray absorptiometry (DXA) results on osteoporosis preventing behaviors (OPB), knowledge of osteoporosis, and health beliefs of men aged 50 years or older (N = 196) was evaluated.
DESIGN
An experimental, 2-group longitudinal design was used. The independent variable was DXA, dependent variables were osteoporosis preventing behaviors, and mediating variables were general knowledge of osteoporosis and Health Belief variables. Half of the men had low bone density. Men diagnosed to be osteoporotic increased their calcium intake.
FINDINGS
Health belief variables predicted calcium intake and/or exercise. In addition, 9 men in the experimental group were taking medications to prevent/restore bone loss at Time 3. Healthcare providers play a significant role in assessing bone loss and preventing and treating osteoporosis in men.
IMPLICATIONS
The cost of a DXA screen is far less than financial and social costs due to osteoporotic fractures.
目的
通过双能X线吸收法（DXA）检测骨密度（BMD）结果对50岁及以上男性（N = 196）预防骨质疏松行为（OPB）、骨质疏松知识及健康信念的影响进行了评估。
设计
采用实验性两组纵向设计。自变量为DXA，因变量为预防骨质疏松行为，中介变量为骨质疏松常识及健康信念变量。一半男性骨密度较低。被诊断为骨质疏松的男性增加了钙摄入量。
研究结果
健康信念变量可预测钙摄入量和/或运动量。此外，实验组有9名男性在第3阶段服用药物预防/恢复骨质流失。医疗服务提供者在评估男性骨质流失以及预防和治疗骨质疏松方面发挥着重要作用。
启示
DXA筛查的成本远低于骨质疏松性骨折造成的经济和社会成本。
