To examine the relationships among health behaviors in older persons and whether they form related groups of behaviors.
Health behaviors (physical activity, alcohol use, nutrition, weight stability, and smoking) were analyzed using factor analysis in two representative samples of two cohorts of Israeli older persons aged 75 to 94. Data collection was conducted during 1989-1992 for the first cohort (N = 1,200) and during 2000-2002 for the second (N = 421).
Four factors of health behaviors were found mostly unrelated: (a) physical activity and weight stability, (b) alcohol use, (c) smoking, and (d) nutrition.
The analysis enables identification of underlying health-behavior dimensions in an understudied population. Furthermore, the findings have important implications for health-promotion policy, indicating that prevention and health-promotion programs for older persons should target each health behavior, and not assume that the practice of any health behavior implies a healthy overall lifestyle in this population.
探讨老年人健康行为之间的关系，以及它们是否形成相关的行为组群。
使用因子分析方法对两个具有代表性的以色列 75 至 94 岁老年人队列的两个样本中的健康行为（身体活动、饮酒、营养、体重稳定和吸烟）进行分析。数据收集于 1989 年至 1992 年进行了第一队列（N=1200），并于 2000 年至 2002 年进行了第二队列（N=421）。
发现了四个主要不相关的健康行为因子：（a）身体活动和体重稳定，（b）饮酒，（c）吸烟，和（d）营养。
该分析能够确定在研究较少的人群中潜在的健康行为维度。此外，这些发现对健康促进政策具有重要意义，表明针对老年人的预防和健康促进计划应针对每个健康行为，而不是假设在该人群中任何健康行为的实践都意味着健康的整体生活方式。
