Association between lung function and disability in African–Americans
BACKGROUND: Impaired lung function is independently associated with higher rates of disability; however, few studies have examined the extent to which this relationship varies by sex. Because men are less likely to have disability, it is expected that the relationship between lung function and disability will be greater among women. METHODS: Logistic regression models were specified to examine the relationship between lung function and disability…
Are Comparisons the Answer to Understanding Behavioral Aspects of Aging in Racial and Ethnic Groups
The knowledge gained from studying diverse populations should help to address inequities and prepare us to deal with the needs of the increasing number of older minorities in this country. At the same time, research that is not properly conducted threatens to lead us astray and misconstrue relationships and outcomes related to behavioral aspects of aging. In this article, we propose that simple comparisons between groups are neither necessary nor…
Studying Biobehavioral Aspects of Health Disparities Among Older Adult Minorities
Origins of Individual Differences in Episodic Memory in the Oldest-Old
The relative importance of genetic and environmental influences on episodic memory in very late life was studied using a quantitative genetic approach. Identical (n = 125) and same-sex fraternal (n = 157) twin pairs, aged 80 and older (mean age = 83.3; SD = 3.1) and without a diagnosis of dementia were tested with seven memory measures: (1-2) Digit Span Forward and Backwards, (3) Prose Recall, (4) Thurstone's picture memory test, and the Memory i…
Genetic and Environmental Influences on Functional Age
Twin analyses were conducted to determine the relative influence of genetic and environmental factors on functional aging. As part of the ongoing Minnesota Twin Study of Adult Development and Aging (MTSADA), measures of 30 demographic, cognitive, physiological, personality, and behavioral variables were available from 140 monozygotic twin pairs and 97 dizygotic twin pairs ranging in age from 27 to 88 years. Functional age was based on a general l…
