To determine the effectiveness of a 3-month home-based booster program for seniors to increase walking.
A longitudinal prospective study.
Perth, Western Australia.
Of the 177 (of 260) program participants and 236 (of 313) controls who initially completed the neighborhood walking intervention, 114 (64%) and 134 (57%) were available for the booster, and 100 and 131 participants completed the entire program, respectively.
A 6-month neighborhood walking intervention was followed 12 months later by a 3-month home-based booster program comprised of print-based materials, a pedometer, and two motivational phone calls.
A self-reported questionnaire was administered at four time points: original intervention, baseline (t1) and 6 months (t2); booster, 18 months (t3) and 21 months (t4). Physical activity levels were measured using the International Physical Activity Questionnaire. Personal and demographic information was collected.
Descriptive statistics and repeated-measures analysis of variance.
The intervention group's mean time spent walking for recreation and mean time spent walking for errands per week showed significant increases between t1 and t2, but the weekly mean time walking for recreation dropped by 52 minutes from t2 to t3. Significant increases were evident from t3 to t4 as a result of the booster. Walking levels for the control group remained stable over the study period.
Physical activity levels of seniors revert once an intervention concludes. A home-based booster program can reactivate physical activity levels. Hence, program planners should include booster sessions for program sustainability.
确定一项针对老年人的为期 3 个月的家庭强化计划在增加步行方面的有效性。
纵向前瞻性研究。
西澳大利亚州珀斯。
在最初完成邻里步行干预的 177 名（260 名中的）项目参与者和 236 名（313 名中的）对照者中，有 114 名（64%）和 134 名（57%）可参加强化计划，分别有 100 名和 131 名参与者完成了整个计划。
在 6 个月的邻里步行干预之后，12 个月后进行为期 3 个月的家庭强化计划，包括基于印刷的材料、计步器和两次动机电话。
在四个时间点进行自我报告问卷调查：原始干预、基线（t1）和 6 个月（t2）；强化，18 个月（t3）和 21 个月（t4）。使用国际体力活动问卷测量体力活动水平。收集个人和人口统计信息。
描述性统计和重复测量方差分析。
干预组每周用于娱乐的步行时间和用于差事的步行时间的平均值在 t1 到 t2 之间显示出显著增加，但从 t2 到 t3 的每周用于娱乐的步行时间减少了 52 分钟。由于强化，t3 到 t4 之间出现了显著增加。对照组的步行水平在整个研究期间保持稳定。
一旦干预结束，老年人的身体活动水平就会恢复。家庭强化计划可以重新激活身体活动水平。因此，项目规划者应在计划可持续性方面包括强化课程。
