Changes in bowel elimination patterns (BEP) for elders admitted to an acute care hospital is essentially unknown. This exploratory study compared a group of 154 elderly with 149 middle-aged subjects from two northern New England hospitals. Interviews, diaries, questionnaires, chart reviews, the Nagley VAS for Confusion, Katz Index of ADL and MEDISGRPS were used in data collection. Analysis included descriptive statistics, t-tests, and multiple regression. During hospitalization, the BEP of both groups changed significantly, but there was no difference between groups on the degree of change. Multiple regression analysis was used to examine the effects of diet and activity on degree of change in BEP while controlling for effects of gender, severity of illness, functional status, and cognitive status; producing a significant coefficient for only the elderly subjects (R2 = .13, p, .01). Therefore, these results support the supposition that activity and diet play a greater role in changes in BEP for elderly patients than middle-aged patients admitted to an acute care hospital.
入住急症医院的老年人肠道排泄模式（BEP）的变化基本未知。这项探索性研究比较了来自新英格兰北部两家医院的154名老年人和149名中年人的情况。通过访谈、日记、问卷、病历审查、用于评估意识模糊的纳格利视觉模拟量表、日常生活活动能力的卡茨指数以及医疗分组进行数据收集。分析包括描述性统计、t检验和多元回归。住院期间，两组的BEP均发生了显著变化，但两组在变化程度上没有差异。多元回归分析用于在控制性别、疾病严重程度、功能状态和认知状态影响的同时，研究饮食和活动对BEP变化程度的影响；结果仅在老年受试者中产生了显著系数（R2 = 0.13，p < 0.01）。因此，这些结果支持这样一种假设，即对于入住急症医院的患者而言，活动和饮食在老年患者BEP变化中所起的作用比中年患者更大。
