老年人比其他年龄段的人更久坐不动。我们试图确定，提供一个带有活动反馈的加速计，并使用Go4Life教育材料咨询年长的受试者是否会增加活动水平。参与者是从辅助生活设施内的独立生活区和明尼苏达州罗切斯特地区的普通公众招募的。49名年龄在65-95岁(79.5+/-7.0岁)、不活动但久坐且超重的受试者参加了为期一年的随机对照交叉试验。在两周的基准期后，第一组接受24周的加速计和使用Go4Life教育材料(www.Go4Life.nia.nih.gov)的咨询，并在接下来的24周接受单独的加速计。第二组在前24周没有干预，然后接受了24周的加速计和基于Go4Life的咨询。两组患者的基线无显著差异。干预与活动量、体重、体脂百分比或血液参数的显著变化无关(p>；0.05)。年龄较大(80-93岁)的受试者比年龄较小(65-79岁)的受试者更不活跃(p=0.003)。在48周的研究过程中，活动水平的增加与体脂百分比的下降有关(p=0.008)。增加活动量有利于老年患者。然而，提供加速计和基于Go4Life的运动咨询计划并没有使这一老年人口的活动水平提高15%。在这个年龄段的老年人中，可能需要其他的运动咨询方法。(C)2014爱思唯尔爱尔兰有限公司。保留所有权利。
Older people are more sedentary than other age groups. We sought to determine if providing an accelerometer with feedback about activity and counseling older subjects using Go4Life educational material would increase activity levels. Participants were recruited from independent living areas within assisted living facilities and the general public in the Rochester, MN area. 49 persons aged 65-95 (79.5 +/- 7.0 years) who were ambulatory but sedentary and overweight participated in this randomized controlled crossover trial for one year. After a baseline period of 2 weeks, group 1 received an accelerometer and counseling using Go4Life educational material (www.Go4Life.nia.nih.gov) for 24 weeks and accelerometer alone for the next 24 weeks. Group 2 had no intervention for the first 24 weeks and then received an accelerometer and Go4Life based counseling for 24 weeks. There were no significant baseline differences between the two groups. The intervention was not associated with a significant change in activity, body weight, % body fat, or blood parameters (p > 0.05). Older (80-93) subjects were less active than younger (65-79) subjects (p = 0.003). Over the course of the 48 week study, an increase in activity level was associated with a decline in % body fat (p = 0.008). Increasing activity levels benefits older patients. However, providing an accelerometer and a Go4Life based exercise counseling program did not result in a 15% improvement in activity levels in this elderly population. Alternate approaches to exercise counseling may be needed in elderly people of this age range. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
