A group of 224 participants in a health promotion program for older adults had complete baseline data, including demographic information, self-perceived mental and physical health ratings, and measures of socialization and health limitations. Participants were offered exercise sessions 3 times a week, weekly health education classes, and a weekly stress management group. Their attendance at these classes varied from no classes to approximately 750 classes. Initially, participants were divided into the following 5 subgroups: 90 with virtually no attendance, and approximately 30 in each of 4 quartiles of class attendance. The group with the lowest attendance (first quartile) was found to be statistically like the group whose participants never attended any classes; these groups were combined. The Kruskal-Wallis One-Way Analysis of Variance was used to test for significant differences among the four groups on the variables of interest. In a comparison of the four groups from lowest to highest attendance, those participants with lowest attendance had lower incomes (P < .05), tended to live alone (P < .01), and were less likely to be able to climb two flights of stairs or walk a half-mile (P < .01) than those in greater attendance groups. Their socialization behaviors were poorer (P < .01), and their health often limited their activities (P < .05).
一组224名参与老年人健康促进项目的参与者拥有完整的基线数据,包括人口统计学信息、自我感知的心理和身体健康评分,以及社交和健康限制的测量指标。参与者可参加每周3次的锻炼课程、每周的健康教育课程和每周一次的压力管理小组。他们参加这些课程的次数从没有参加到大约750次不等。最初,参与者被分为以下5个亚组:90人几乎没有参加课程,其余4个出勤四分位数组每组约30人。发现出勤率最低的组(第一四分位数)在统计学上与那些从未参加任何课程的参与者组相似;这两组被合并。采用Kruskal-Wallis单向方差分析来检验四组在感兴趣变量上的显著差异。在对出勤率从低到高的四组进行比较时,出勤率最低的那些参与者比出勤率较高组的参与者收入更低(P < .05),倾向于独居(P < .01),并且爬两层楼梯或走半英里的可能性更小(P < .01)。他们的社交行为更差(P < .01),并且他们的健康状况常常限制了他们的活动(P < .05)。
