Guided by the social comparison theory, we examined correlates of the discrepancy between chronological and felt ages in three age groups of community-dwelling older adults: 65 to 69, 70 to 79, and 80 and older.
Data from the National Health and Aging Trends Study and linear regression models were used to test the hypothesis that age discrepancy would be significantly associated with objective health indicators among those in the 65 to 69 and 70 to 79 age groups but not among the 80+ group.
Objective health indicators were significantly associated with age discrepancy only in the 70 to 79 age group, while subjective health perceptions and psychological well-being were significantly associated with age discrepancy in all age groups.
The correlates of the discrepancy in the 65 to 69 age group appear to resemble those in the 80+ group more than those in the 70 to 79 age group. Further research is needed to identify the determinants of age group differences.
本研究以社会比较理论为指导,考察了三个年龄段(65-69 岁、70-79 岁和 80 岁及以上)社区居住的老年人中实际年龄与自我感知年龄差异的相关因素。
本研究使用国家健康老龄化趋势研究的数据和线性回归模型来检验以下假设:在 65-69 岁和 70-79 岁年龄组中,年龄差异与客观健康指标显著相关,但在 80 岁及以上年龄组中不相关。
仅在 70-79 岁年龄组中,客观健康指标与年龄差异显著相关,而主观健康感知和心理幸福感与所有年龄组的年龄差异均显著相关。
65-69 岁年龄组差异的相关因素似乎与 80 岁及以上年龄组更相似,而不是与 70-79 岁年龄组更相似。需要进一步研究以确定年龄组差异的决定因素。
