This experimental longitudinal study was designed to examine the relationship between having a bone density through dual energy X ray absorptiometry (DXA) and osteoporosis preventing behaviors (OPB) among healthy postmenopausal women.
Subjects were 203 healthy community-based women 50-65 years of age. Mediating variables were general knowledge of osteoporosis and revised health belief model variables. Treatment group women (n = 101) had a DXA screen and control group women (n = 102) did not. Study questionnaires were completed at three time points; initially and at 6 months and 12 months.
Repeated measures ANOVA revealed treatment group women scored significantly higher on perceived susceptibility and calcium intake. Wilks's Lambda F revealed a significant difference in use of osteoporosis preventing medications.
Personal knowledge gained from DXAs increased perceived susceptibility to osteoporosis, calcium intake, and use of osteoporosis preventing medications and appears to be an effective intervention in promoting OPB in younger postmenopausal women.
本实验性纵向研究旨在探讨通过双能X线吸收法（DXA）检测骨密度与健康绝经后女性骨质疏松预防行为（OPB）之间的关系。
研究对象为203名年龄在50 - 65岁之间、来自社区的健康女性。中介变量为骨质疏松的一般知识和修订后的健康信念模型变量。治疗组女性（n = 101）接受了DXA筛查，对照组女性（n = 102）未接受。研究问卷在三个时间点完成，即初始阶段、6个月和12个月时。
重复测量方差分析显示，治疗组女性在感知易感性和钙摄入量方面得分显著更高。威尔克斯λ检验显示，在使用骨质疏松预防药物方面存在显著差异。
通过DXA获得的个人知识增加了对骨质疏松的感知易感性、钙摄入量以及骨质疏松预防药物的使用，并且似乎是促进年轻绝经后女性OPB的一种有效干预措施。
