The Aging, Demographics, and Memory Study: study design and methods.

OBJECTIVE: We describe the design and methods of the Aging, Demographics, and Memory Study (ADAMS), a new national study that will provide data on the antecedents, prevalence, outcomes, and costs of dementia and "cognitive impairment, not demented" (CIND) using a unique study design based on the nationally representative Health and Retirement Study (HRS). We also illustrate potential uses of the ADAMS data and provide information to interested researchers on obtaining ADAMS and HRS data. METHODS: The ADAMS is the first population-based study of dementia in the United States to include subjects from all regions of the country, while at the same time using a single standardized diagnostic protocol in a community-based sample. A sample of 856 individuals age 70 or older who were participants in the ongoing HRS received an extensive in-home clinical and neuropsychological assessment to determine a diagnosis of normal, CIND, or dementia. Within the CIND and dementia categories, subcategories (e.g. Alzheimer's disease, vascular dementia) were assigned to denote the etiology of cognitive impairment. CONCLUSION: Linking the ADAMS dementia clinical assessment data to the wealth of available longitudinal HRS data on health, health care utilization, informal care, and economic resources and behavior, will provide a unique opportunity to study the onset of CIND and dementia in a nationally representative population-based sample, as well as the risk factors, prevalence, outcomes, and costs of CIND and dementia.

Does urinary incontinence affect middle-aged and older women's time use and activity patterns?

OBJECTIVE: To investigate the relationship between urinary incontinence and women's levels and hours of participation in 31 activities. METHODS: A subset of panel members from the Health and Retirement Study completed the self-administered Consumption and Activities Mail Survey questionnaire in 2001. These data were linked with Health and Retirement Study 2000 data. Analyses were limited to 2,190 female Consumption and Activities Mail Survey self-respondents born in 1947 or earlier. Logistic regression was used to predict activity participation. Linear regression was used to predict the number of hours of participation. RESULTS: The hypothesis that urinary incontinence affects women's time use and activity patterns was supported. Compared with the continent women, the incontinent women were less likely to have house cleaned, shopped, physically shown affection, or attended religious services in the recent past; and were more likely to have watched television or made music by singing or playing an instrument. Compared with continent activity participants, incontinent participants reported significantly fewer hours spent walking, communicating with friends and family by telephone or e-mail, working for pay, using a computer, and engaging in personal grooming and hygiene. CONCLUSION: These findings substantiate prior work on the relationship between urinary incontinence and quality of life, and suggest a useful route for educating patients about the impact of urinary incontinence. Clinicians must be alert to opportunities for encouraging incontinent women to be active. It is also important to consider the implications for time use and activity patterns when advising patients about treatment and management options. LEVEL OF EVIDENCE: II-2.

A lengthy look at the daily grind: time series analysis of events, mood, stress, and satisfaction.

The present study investigated processes by which job stress and satisfaction unfold over time by examining the relations between daily stressful events, mood, and these variables. Using a Web-based daily survey of stressor events, perceived strain, mood, and job satisfaction completed by 14 university workers, 1,060 occasions of data were collected. Transfer function analysis, a multivariate version of time series analysis, was used to examine the data for relationships among the measured variables after factoring out the contaminating influences of serial dependency. Results revealed a contrast effect in which a stressful event associated positively with higher strain on the same day and associated negatively with strain on the following day. Perceived strain increased over the course of a semester for a majority of participants, suggesting that effects of stress build over time. Finally, the data were consistent with the notion that job satisfaction is a distal outcome that is mediated by perceived strain.
