The purpose of this evaluation was to evaluate the effectiveness of a multidisciplinary educational and exercise program for individuals at risk for osteoporosis-related fractures.
The Highmark Osteoporosis Prevention and Education (HOPE) program is an ongoing, 8-week program with two postintervention follow-up assessments at 6 months and 2 years. Adults (n = 375) with osteoporosis or significant risk factors, most already engaged in healthy behaviors, self-selected for participation. Baseline measures included bone mineral density scans; fitness assessments; and surveys of depression, exercise, and nutrition behaviors. At course end and 6-month follow-up, assessments were repeated for fitness measures, depression, and exercise and nutrition adherence. Two-year postprogram assessments included bone mineral density scans and adherence measures.
Paired t-tests showed significant improvements at course end in all measures (p < .0001) for the 87% completing the course. A repeated measure analysis of variance after 2 years with 79% retention indicated that adherence to nutrition recommendations was maintained at 2-year follow-up (p < .0001), whereas exercise adherence decreased but continued to exceed baseline measures (p < .0001). At 2 years, participants averaged two strength training sessions and 131 minutes aerobic exercise per week and consumed an average of 97% and 99% of the recommended calcium and vitamin D.
Although findings of this nonexperimental study are limited because of lack of a control group, the HOPE program suggests that a comprehensive community-based education and behavior change program can significantly reduce risk factors for osteoporosis and related fractures. Participants maintained lifestyle modifications for a minimum of 2 years despite advancing age.
本评估旨在评价一项针对骨质疏松相关骨折高危个体的多学科教育与锻炼项目的效果。
“高马克骨质疏松预防与教育(HOPE)项目”是一个为期8周的项目,在干预后6个月和2年进行两次随访评估。患有骨质疏松或有显著风险因素的成年人(n = 375),其中大多数已经养成了健康的行为习惯,自行选择参与该项目。基线测量包括骨密度扫描、体能评估以及对抑郁、锻炼和营养行为的调查。在课程结束时和6个月随访时,重复进行体能测量、抑郁以及锻炼和营养依从性的评估。项目结束两年后的评估包括骨密度扫描和依从性测量。
配对t检验显示,完成课程的87%的参与者在课程结束时所有测量指标均有显著改善(p < .0001)。两年后,79%的参与者进行重复测量方差分析,结果表明,在两年随访时,对营养建议的依从性得以维持(p < .0001),而锻炼依从性虽有所下降但仍高于基线测量值(p < .0001)。在两年时,参与者平均每周进行两次力量训练课程和131分钟有氧运动,钙和维生素D的摄入量平均分别达到推荐量的97%和99%。
尽管由于缺乏对照组,这项非实验性研究的结果有限,但HOPE项目表明,一个基于社区的综合教育和行为改变项目可以显著降低骨质疏松和相关骨折的风险因素。尽管年龄增长,参与者至少在两年内维持了生活方式的改变。
