Given limited longitudinal research with caregivers (CGs, n = 122) of spouses with Alzheimer disease, and demographically matched noncaregivers (NCGs, n = 117), we compared these groups on psychological distress (anxiety, depression), burden, and health behaviors over 2 years. Analyses examined group differences in relationships of micronutrient recommended daily allowances (RDAs) and physical activity considering hours of care, psychological distress, and burden. Participants were measured and assessed on whether they met micronutrient intake and physical activity totaled over an average week. Regression analyses showed a total effect whereby NCGs had greater increases in meeting micronutrient allowances (RDAs) than CGs ( = 10.91, standard error [SE] = 4.74, 95% confidence interval [CI]: 1.56-20.26). Additionally, over time, NCGs had greater increases in physical activity, which was mediated by hours of care ( = 0.149, SE = 0.060, 95% CI: 0.034-0.270). These results suggest CGs may lack proper nutrients, and care hours may influence their health behaviors.
由于针对配偶患有阿尔茨海默病的照顾者 (CGs，n=122) 的纵向研究有限，并且与人口统计学匹配的非照顾者 (NCGs，n=117)，我们在 2 年内比较了这两组人的心理困扰 (焦虑、抑郁)、负担和健康行为。分析考虑了照顾时间、心理困扰和负担，考察了微量营养素推荐日摄入量 (RDA) 和体育活动与群体差异的关系。参与者被测量并评估他们是否在一周的平均时间内摄入了足够的微量营养素和进行了足够的体育活动。回归分析显示出总效应，即与 CGs 相比，NCGs 更有可能增加满足微量营养素摄入量的情况 (RDA) ( = 10.91，标准误差 [SE] = 4.74，95%置信区间 [CI]：1.56-20.26)。此外，随着时间的推移，NCGs 增加了更多的体育活动，这是由照顾时间介导的 ( = 0.149，SE = 0.060，95% CI：0.034-0.270)。这些结果表明，CGs 可能缺乏适当的营养，而照顾时间可能会影响他们的健康行为。
