There is a notable gap in translating efficacious interventions to community-based organizations. Further, physical activity interventions have been less successful in promoting longer-term maintenance.
This study examined 6-month maintenance of improvements seen in Active for Life (AFL), a translational research initiative.
Participants from seven of 12 AFL sites enrolled in Years 3 and 4 were surveyed 6 months after completing the 6-month telephone-based Active Choices program (AC, one site) or the 20-week or 12-week group-based Active Living Every Day program (ALED, six sites). Repeated measures analyses controlled for site clustering and covariates. Programs were implemented from 2003 to 2007 and analysis was conducted in 2009.
For the AC (n=368) and ALED (n=2151) programs, respectively, participants were aged 72.0 and 70.8 years on average, were 70% and 78% non-Hispanic white, and were 72% and 83% women; 46% and 50% returned 6-month follow-up surveys. For AC, improvements from pre- to post-test were maintained at follow-up for physical activity; satisfaction with body function (SBF); and BMI. For ALED Year 3, there was a decrease at follow-up for physical activity and SBF. Body mass index decreased from pretest to follow-up. For ALED Year 4, increases in physical activity and reductions in BMI were maintained at follow-up. Satisfaction with body function increased from pretest to 12 weeks post-test, declined at 20 weeks, and was maintained at follow-up.
Improvements were generally maintained at the 6-month follow-up. When behavioral decay occurred, follow-up values remained more favorable than at pretest. Given the broad reach of this translational initiative, the results suggest the viability of evidence-based programming as an effective public health practice.
将有效的干预措施转化为社区组织存在显著差距。此外,身体活动干预在促进长期维持方面效果较差。
本研究检验了积极生活(AFL)的 6 个月维持效果,这是一项转化研究计划。
来自 12 个 AFL 站点中的 7 个站点的参与者参加了第 3 年和第 4 年的研究,在完成 6 个月的基于电话的主动选择计划(AC,一个站点)或 20 周或 12 周的基于小组的日常积极生活计划(ALED,六个站点)6 个月后进行调查。重复测量分析控制了站点聚类和协变量。这些项目从 2003 年到 2007 年实施,分析于 2009 年进行。
对于 AC(n=368)和 ALED(n=2151)计划,参与者的平均年龄分别为 72.0 岁和 70.8 岁,分别有 70%和 78%是非西班牙裔白人,分别有 72%和 83%是女性;46%和 50%的人返回了 6 个月的随访调查。对于 AC,从预测试到随访测试,身体活动、身体功能满意度(SBF)和 BMI 都保持了改善。对于 ALED 第 3 年,随访时身体活动和 SBF 下降。体重指数从预测试到随访测试都有所下降。对于 ALED 第 4 年,身体活动的增加和 BMI 的减少都保持了随访。从预测试到 12 周随访,身体功能满意度增加,20 周后下降,随访时保持不变。
随访时总体上保持了改善。当行为衰减发生时,随访值仍比预测试更有利。鉴于这一转化计划的广泛影响,结果表明基于证据的计划作为一种有效的公共卫生实践是可行的。
