Binary and Nonbinary Measures of Successful Aging: Do They Yield Comparable Conclusions?

Multidimensional Factors Affecting Successful Aging among Empty-Nesters in China Based on Social-Ecological System Theory

BACKGROUND

This study aims to identify the status of successful aging and the factors influencing empty-nest elderly in China based on the social-ecological system theory.

METHODS

The data came from the follow-up survey (2018) of the China Health and Retirement Longitudinal Study and 3074 empty-nesters aged 60 and over are included. Chi-squared tests and logistic regressions were used to identify factors associated with successful aging.

RESULTS

The successful aging rate of empty-nesters in China was 5.9%. The results of the multifactor analysis showed that younger age, higher education level, good self-rated health, good hearing, high life satisfaction, availability of financial resources at the microsystem level, higher frequency of contact with children at the mesosystem level, and medical insurance at the macrosystem level were the contributing influencing factors for successful aging of empty-nesters in China.

CONCLUSION

This study is an important attempt to explore the successful aging of empty-nesters in China. Because this study is based on social-ecological system theory, it confirms the important role of individual characteristics of older adults and their surrounding environment in achieving successful aging. Therefore, we should pay attention not only to the individual characteristics of the elderly, but also to the role of the surrounding environment on the health of the elderly, so that we can develop intervention measures to promote their successful aging.

Successful ageing in the oldest old: objectively and subjectively measured evidence from a population-based survey in Germany

Despite rapid increase of people aged 80 and over, concepts of successful ageing (SA) are primarily examined for people below that age. Therefore, successful ageing was examined in a population-based representative sample of N = 1863 people aged 80 to 102 (NRW80+) with 11% living in institutionalized settings. In this survey on quality of life and well-being, multiple linear and logistic regression models were used to calculate the distribution of successful agers. According to Rowe and Kahn's objective definition, 9% of the sample aged successfully, but one-third (33%) still met four to five SA criteria. This is in line with the theoretical a priori criterion of 10% in a normal distribution of a sample, while 80% age normally and 10% pathologically. However, averages of life satisfaction, affective well-being, positive ageing experience and valuation of life were high. The majority of the oldest old (65%) are successful agers in their own subjective perception, which is not in line with objective measurements. Moreover, 11% of objectively measured successful agers do not meet subjective criteria. These empirical findings reveal a remarkable discrepancy between objective and subjective criteria of SA. Future research on concepts that define successful ageing for the oldest old should consider more holistic markers of success, e.g., outcomes of productive social engagement.
