To evaluate the effects of an exercise and scheduled-toileting intervention on appetite and constipation in nursing home (NH) residents.
A controlled, clinical intervention trial with 89 residents in two NHs. Research staff provided exercise and toileting assistance every two hours, four times per day, five days a week for 32 weeks. Oral food and fluid consumption during meals was measured at baseline, eight and 32 weeks. Bowel movement frequency was measured at baseline and 32 weeks.
The intervention group showed significant improvements or maintenance across all measures of daily physical activity, functional performance, and strength compared to the control group. Participants in both groups consumed an average of approximately 55% of meals at all three time points (approximately 1100 calories/day) with no change over time in either group. There was also no change in the frequency of bowel movements in either group, which averaged less than one in two days for both groups; and, approximately one-half of all participants had no bowel movement in two days.
An exercise and scheduled-toileting intervention alone is not sufficient to improve oral food and fluid consumption during meals and bowel movement frequency in NH residents.
评估运动和定时排便干预对养老院居民食欲和便秘的影响。
对两家养老院的89名居民进行一项对照临床干预试验。研究人员每两小时提供一次运动和排便协助，每天4次，每周5天，持续32周。在基线、第8周和第32周测量用餐期间的口服食物和液体摄入量。在基线和第32周测量排便频率。
与对照组相比，干预组在日常身体活动、功能表现和力量的所有测量指标上均有显著改善或维持。两组参与者在所有三个时间点平均摄入约55%的餐食（约1100卡路里/天），两组随时间均无变化。两组的排便频率也没有变化，两组平均每两天排便少于一次；并且，所有参与者中约有一半在两天内没有排便。
单独的运动和定时排便干预不足以改善养老院居民用餐期间的口服食物和液体摄入量以及排便频率。
