项目摘要

DESCRIPTION (provided by applicant): Prevention of osteoporosis is an important nursing and health care concern. This study's purpose is to evaluate the effect of dual energy x-ray absorptiometry (DXA) screening on Osteoporosis Preventing Behaviors (OPB) of men ages 50 years and older at 6 and 12 months post DXA. It is based on the Revised Health Belief Model (RHBM) and proposes that bone density assessment will provide the stimulus to get men to attend to information about osteoporosis, learn more about osteoporosis, alter their health beliefs, and perform more osteoporosis preventing behaviors (OPB). The independent variable is DXA screening, an objective measure of bone density, hypothesized to affect the dependent OPB variables (calcium intake, exercise, smoking) through the mediating variables of knowledge and RHBM (susceptibility, seriousness, benefits, barriers, motivation, and self-efficacy). The mediating variables, in turn, will influence the OPB. The Specific aims of this study are to: 1) Compare Revised Health Belief Model (RHBM) variables and Knowledge of Osteoporosis between men who have a first DXA and those who do not; 2) Compare performance of OPB between men who have a first DXA and those who do not; 3) Determine which variables (DXA, RHBM variables, Knowledge of Osteoporosis) are most predictive of the performance of OPB; 4) Determine whether Health Beliefs are related to the performance of OPB; 5) Determine whether BMD results influence RHBM, knowledge, and/or OPB; 6) Determine the mechanism through which DXA affects OPB. The research questions are: 1) Does having a DXA cause an increase in Knowledge of Osteoporosis? 2) Does having a DXA cause an increase in Revised Health Belief scores? 3) Does having a DXA cause an increase in OPB? 4) Does an increase in Knowledge of Osteoporosis cause and increase in OPB? 5) Does an increase in Revised Health Belief variable scores (or a decrease in barrier scores) cause an increase in OPB scores? 6) Does having a DXA cause an increase in OPB when controlling for Knowledge of Osteoporosis and Revised Health Belief scores? 7) For the subsample of men who have DXA: Is there a difference in OPB among men with normal DXA T-scores (>-1), osteopenic T-scores (-1.0 to 2.5), and osteoporotic T-scores (<-2.5) when controlling for knowledge? 8) Does Knowledge of Osteoporosis or Revised Health Benefits have the stronger casual effect on OPB? 9) What are the overall effect parameters of the proposed model? 10) What are the effects of specific dimensions of the RHBM on OPB? Statistical analyses are tailored to the aims and derived hypotheses.

描述（由申请人提供）：预防骨质疏松症是重要的护理和医疗保健问题。这项研究的目的是评估双能X射线吸收仪（DXA）筛查对DXA后6和12个月大50岁以上男性的骨质疏松症预防骨质疏松症的影响。它基于修订后的健康信念模型（RHBM），并提出骨密度评估将提供刺激性，以使男性参与有关骨质疏松症的信息，了解有关骨质疏松症的更多信息，改变其健康信念，并执行更多的骨质疏松症（OPB）（OPB））。独立变量是DXA筛选，是对骨密度的客观度量，假设通过知识和RHBM的中介变量（易感性，严肃性，优势，障碍，动机，自我动机，和自我动机，和自我攻击，锻炼，运动，动机，自我，动机，动机，和自我动机，动机，动机和自我）来影响依赖的OPB变量（钙的摄入量，运动，吸烟） -功效）。介导变量反过来会影响OPB。这项研究的具体目的是：1）比较修订后的健康信念模型（RHBM）变量以及对拥有第一个DXA的男性与没有的男性之间的骨质疏松知识； 2）比较拥有第一个DXA的男性与没有的男性的表现； 3）确定哪些变量（DXA，RHBM变量，骨质疏松知识）最可预测OPB的性能； 4）确定健康信念是否与OPB的表现有关； 5）确定BMD结果是否影响RHBM，知识和/或OPB； 6）确定DXA影响OPB的机制。研究问题是：1）具有DXA是否会增加骨质疏松知识？ 2）拥有DXA是否会增加修订的健康信念评分？ 3）具有DXA会导致OPB增加吗？ 4）对骨质疏松症的知识增加并增加了OPB的增加？ 5）修订后的健康信念变量得分（或屏障得分的下降）是否会增加OPB分数的提高？ 6）在控制骨质疏松知识和修订健康信念评分时，具有DXA会导致OPB增加吗？ 7）对于患有DXA的男性的子样本：DXA T得分（> -1），骨质减少T分数（-1.0至2.5）和骨质疏松性T分数（<-- <-- 2.5）在控制知识时？ 8）对骨质疏松症或修订的健康益处的知识是否对OPB具有更强的休闲作用？ 9）所提出模型的总体效应参数是什么？ 10）RHBM对OPB的特定维度有什么影响？统计分析是针对目标和衍生假设量身定制的。
