Abstract Background: Subjective age (SA) has been found to be a biopsychosocial marker of aging, yet little is known about factors that influence SA development. This study examined factors influencing SA using longitudinal data of community-dwelling older Japanese. Methods: Data drawn from the Kusatsu Longitudinal Study were collected during annual health check-ups in 2017 and 2018 from participants (aged 65-95) who completed all the measurement items used for this analysis (N=981). SA was indexed by asking participants to specify in years how old they felt. Proportional discrepancy scores ((subjective age - chronological age)/chronological age ×100) were calculated to indicate younger or older SAs and used as a dependent variable. As influencing factors of SA, chronological age, sex, years of schooling, history of smoking, cognitive function (using MMSE scores, range 14-30 at baseline), depressive symptoms, physical function (gait speed), and social function (employment status) were examined. Analyses were performed with random-effects GLS regression models. Results: Significant partial regression coefficients were found for cognitive function (0.48%, CI: 0.18, 0.79), years of schooling (-0.42%, CI: -0.69, -0.15), depressive symptoms (0.32%, CI: 0.11, 0.53), and chronological age (-0.18%, CI: -0.30, -0.68). Implications: This study found that older age and longer years of schooling were associated with younger SA, while better cognition and depressive symptoms were linked to older SA. Better cognition being associated with older SA was inconsistent with existing studies. This may be due in part to the association of better cognition and the level of satisfaction influenced by awareness of age-related physical/social changes.

Activity Restriction

ABSTRACTBackground:Chronic pain is likely to lead to depressive symptoms, but the nature of this relationship is not completely clear. The aim of the present study is to analyze the role of activity restriction in the pain-depression relationship in older people, and to test the hypothesis that this role is more relevant in community-dwelling older people than in nursing home residents.Method:Depressive symptoms, pain intensity, and activity restriction were measured in a sample of 208 older adults with osteoarthritis, 102 living in nursing homes (NH), and 106 in the community. Analyses were carried out using moderation and moderated mediation analyses approach, treating activity restriction as a confounder.Results:Results showed a significant confounding effect of activity restriction, interaction effect between pain intensity and activity restriction on depression, and modifying effect of pain intensity on depression by adding activity restriction into the model. These results suggest a potential mediating and moderating effects of activity restriction. Moreover, analyses suggest that, surprisingly, the strength of the mediation could be higher in nursing homes.Conclusions:Overall, it may be that what is really important to emotional well-being is not so much pain itself, but rather the way in which the pain alters older people's lives. The greater strength of the mediation in NH might be understood within the scope of self-determination theory. Generally speaking, the NH context has been considered as a coercive setting, promoting non-autonomous orientation. In this context, when events are objectively coercive, people may lack perceived autonomy and hence be at greater risk of depression.

Abstract Background To establish trajectories of cognitive and motor function, and to determine the sequence of change across individual tests in community-dwelling individuals aged 45–90 years. Method Between 1997 and 2016, we repeatedly assessed cognitive function with 5 tests in 9514 participants aged 45–90 years from the population-based Rotterdam Study. Between 1999 and 2016, we measured motor function with 3 tests in 8297 participants. All participants were free from dementia, stroke, and parkinsonism. We assessed overall and education-specific cognitive and motor trajectories using linear mixed models with age as time scale. Next, we determined the sequence of change across individual tests. Results The number of assessments per participant ranged between 1 and 6 (mean interval, years [SD]: 5.1 [1.4]) for cognitive function, and 1 and 4 (5.4 [1.4]) for motor function. Cognitive and motor trajectories declined linearly between ages 45 and 65 years, followed by steeper declines after ages 65–70 years. Lower educated participants had lower cognitive function at age 45 years (baseline), and declined faster on most cognitive, but not on motor tests than higher educated participants. Up to a 25-year age difference between the fastest and slowest declining test scores was observed. Conclusions On a population-level, cognitive and motor function decline similarly. Compared to higher educated individuals, lower educated individuals had lower cognitive function at baseline, and a faster rate of decline thereafter. These educational-effects were not seen for motor function. These findings benefit the understanding of the natural course of cognitive and motor function during aging, and highlight the role of education in the preservation of cognitive but not motor function.

Moderating Role

The current study examined the moderating role of adherence to a healthy prudent diet and an unhealthy Western diet in the relationship between perceived stress and cognitive function among community-dwelling older adults. It was hypothesized that the association between perceived stress and cognition would be buffered by prudent diet and exacerbated by Western diet intake. 201 adults aged 60 and older participated in the study. Prudent diet was a significant effect-modifier, such that higher perceived stress was associated with poorer executive functioning at low levels of prudent diet. Prudent diet did not moderate the association between perceived stress and episodic memory. Western diet was not a significant effect-modifier in the perceived stress-cognition relationship. These findings provide preliminary evidence that a healthy diet may buffer the association between perceived stress and executive function in older adults. Future research with a more diverse sample is needed to confirm these findings.
