Health-Related Quality of Life in Community-Dwelling Older Whites and African Americans
Findings suggest that general well-being serves as an intervening step between physical and mental health in both White and African American older adults
The Association Between Social Resources and Cognitive Change in Older Adults
We examined associations between multiple aspects of social resources and 5-year change in performance on different domains of cognitive function. Results indicated that lower satisfaction with support was associated with decline in episodic memory performance over 5 years. We also found significant interactions between age and social networks of family and friends and satisfaction with support for the separate cognitive domains. The results sugg…
Negative Life Events and Cognitive Performance in a Population of Older Adults
The findings support previous research indicating that using estimates of individual stressors rather than aggregate stress measures increases the predictive validity of stress measurement. Furthermore, the individual negative life events can have both a positive and a negative effect, which nullify one another when using the sum score of events
Depressive Symptoms Among African American and White Older Adults
Guided by a stress and coping model, we explored determinants of depressive symptoms among community samples of older African Americans (n=255) and older Whites (n=452). We gave focus to the effects of demographic variables, physical health constraints (chronic conditions and functional disability), and psychosocial attributes (sense of mastery, religiosity, social support, and satisfaction with support), along with their interactive roles. We id…
Complexity of Work and Risk of Alzheimer's Disease
We examined the association between risk of dementia or Alzheimer's disease (AD) and occupation by using measures of complexity of work with data, people, and things. The study included 10,079 members of the population-based Swedish Twin Registry who were participants in the HARMONY study. We diagnosed dementia by means of a two-stage procedure--cognitive impairment screening followed by full clinical evaluation. We analyzed data with case-contro…
Determinants of a Sense of Mastery in African American and White Older Adults
Although African American older adults had a lower sense of mastery than Whites, their feelings of mastery were less likely to be diminished by old age and poor health and more likely to be enhanced by religiosity. Possible explanations for cross-racial differences are discussed, as are implications
The Role of Mastery and Social Resources in the Associations Between Disability and Depression in Later Life
PURPOSE: Although disability is widely acknowledged as a risk factor for late-life depression, few studies have studied the potential of psychosocial factors to alter the association between disability and depression. The present study assessed the impacts of mastery and social resources (social network, social support, and satisfaction with support) on depression and, in particular, whether they modify the link between disability and depression.…
The Role of Neuroticism in the Association Between Performance-Based and Self-Reported Measures of Mobility
Given a certain level of physical performance, individuals who scored high on neuroticism were more likely to report disability. Also, the combination of poor performance and high neuroticism increased self-reported disability. The findings suggest that neuroticism may play an important role in subjective perception and should be considered in the interpretation of data based on self-reports
Education and the Risk of Alzheimer's Disease
The association between dementia and education was studied in 143 twin pairs discordant for dementia, using a matched-pair design, and in 221 dementia cases and 442 unrelated controls from the same twin registry, using a case-control design. Low education was defined as 6 years or less of schooling. Case-control analyses with prevalent cases showed low education to be a risk for Alzheimer's disease but not dementia in general. Low education did n…
Cognitive Function and Apolipoprotein E in Very Old Adults
Our findings suggest that the APOE epsilon4 allele may be included among the variables that predict high cognitive function in cognitively intact, very old adults. Although the presence or absence of the epsilon4 allele is known to be related to the risk of dementia, it also appears to be related to maintaining high levels of cognitive function in old age
