Objective. To evaluate the effectiveness of a 12-week home-based postal and telephone physical activity and nutrition pilot program for seniors. Methods. The program was delivered by mailed material and telephone calls. The main intervention consisted of a booklet tailored for seniors containing information on dietary guidelines, recommended physical activity levels, and goal setting. Dietary and walking activity outcomes were collected via a self-administered postal questionnaire pre- and postintervention and analysed using linear mixed regressions. Of the 270 seniors recruited, half were randomly selected for the program while others served as the control group. Results. The program elicited favourable responses. Postintervention walking for exercise/recreation showed an average gain of 27 minutes per week for the participants in contrast to an average drop of 5 minutes for the controls (P < .01). Little change was evident in errand walking for both groups. The intervention group (n = 114) demonstrated a significant increase in fibre intake (P < .01) but no reduction in fat intake (P > .05) compared to controls (n = 134). Conclusions. The participants became more aware of their health and wellbeing after the pilot program, which was successful in increasing time spent walking for recreation and improving fibre intake.
目的。评估一项为期12周、以家庭为基础、通过邮寄和电话开展的针对老年人的身体活动与营养试点项目的效果。方法。该项目通过邮寄材料和电话进行。主要干预措施包括一本为老年人量身定制的手册，其中包含饮食指南、推荐的身体活动水平和目标设定等信息。通过干预前后自行填写的邮寄问卷收集饮食和步行活动结果，并使用线性混合回归进行分析。在招募的270名老年人中，一半被随机挑选参加该项目，另一半作为对照组。结果。该项目得到了积极的反馈。干预后，参与项目的人员每周用于锻炼/娱乐的步行时间平均增加了27分钟，而对照组平均减少了5分钟（P < .01）。两组用于跑腿的步行时间变化不大。与对照组（n = 134）相比，干预组（n = 114）的纤维摄入量显著增加（P < .01），但脂肪摄入量没有减少（P > .05）。结论。在试点项目实施后，参与者对自身健康和幸福的意识增强，该项目成功增加了用于娱乐的步行时间并改善了纤维摄入量。
