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.

Functional impairment as a risk factor for urinary incontinence among older Americans.

AIMS: Using a large nationally representative sample of older Americans we investigate four domains of functional impairment as possible risk factors for the subsequent development of urinary incontinence (UI) symptoms. METHODS: Data from three waves (1993, 1995, 1998) of the Asset and Health Dynamics among the Oldest Old (AHEAD) survey were used to model the effects of functional impairment on the onset of UI symptoms. RESULTS: A greater number of serious chronic conditions and functional impairment in the lower body mobility domain increased the odds of the onset of mild UI (vs. remaining continent). Factors that contributed to greater odds of the onset of severe UI (vs. remaining continent) were older age, being represented by a proxy respondent, and functional impairment in the strength domain. CONCLUSIONS: Understanding the possible relationship between functional impairment and UI is an important step toward developing appropriate interventions for the prevention, treatment, or management of urine loss.

Is urinary incontinence a barrier to exercise in women?

OBJECTIVE: To describe the prevalence of urinary incontinence during exercise in women, estimate whether exercise intensity is related to leakage severity, and report women's assessments of incontinence as a barrier to exercise. METHODS: Questionnaires were mailed to 5,130 women aged 18-60 years drawn from National Family Opinion research panels. Physical activity levels were assessed by the International Physical Activity Questionnaire. Urinary incontinence, defined as involuntary leakage in the last 30 days, was assessed with the Sandvik Severity Index and a global measure of bother. Prevalence estimates were adjusted via post-stratification weighting. RESULTS: A total of 3,364 eligible women responded (68%), of whom 34.6% were insufficiently active (95% confidence interval [CI] 32.7-36.5%), 29.7% were sufficiently active (95% CI 27.9-31.5%), and 35.7% were highly active (95% CI 33.8-37.6%). Urinary incontinence prevalence was 34.3% (95% CI 32.5-36.1%). One in seven women experienced urinary leakage during physical activity; this was more common among highly active (15.9%) than less active women (11.8%) (P = .01). After adjusting for age, comorbidities, education, and race, women with very severe incontinence were 2.64 times (95% CI 1.25-5.55) more likely to be insufficiently active than continent women. Incontinence was a moderate or substantial barrier to exercise for 9.8% (95% CI 8.8-10.9%) of women. Of incontinent women, the proportion for whom incontinence was a moderate or substantial barrier to exercise increased with each severity category: 9.2%, slight; 37.8%, moderate; 64.6%, severe; and 85.3%, very severe (P < .01). CONCLUSION: Urinary incontinence is perceived as a barrier to exercise, particularly by women with more severe leakage.

Evaluating potentially modifiable risk factors for prevalent and incident nocturia in older adults.

OBJECTIVES: To examine associations between nocturia and potentially modifiable risk factors in older adults. DESIGN: Secondary analysis of cross-sectional and longitudinal data. SETTING: Respondents were selected using population-based sampling, drawing from a single Michigan county in 1983. They were followed through 1990. PARTICIPANTS: Community-living adults aged 60 and older. MEASUREMENTS: Episodes of nocturia, development of nocturia at 2 years after baseline survey, age, sex, hypertension, diabetes mellitus, drinking fluids before bedtime, amount of fluid intake before bedtime, diuretic use, and 24-hour coffee intake. All measures were self-reported. RESULTS: Bivariate cross-sectional analysis revealed significant associations with two or more episodes of nocturia for hypertension (odds ratio (OR)=1.7, 95% confidence interval (CI)=1.37-2.1), diabetes mellitus (OR=1.51, 95% CI=1.1-2.0), diuretic use (OR=1.7, 95% CI=1.3-2.1), age (OR=1.05 per additional year over 60, 95% 1.03-1.06), and number of cups of coffee (OR=0.93 for each cup of coffee, 95% CI=0.89-0.97). In multivariate analysis, hypertension (OR=1.52, 95% CI=1.2-1.9), diuretic use (OR=1.3, 95% 95% CI=1.0-1.7), and age (OR=1.04 per additional year over 60, 95% 1.03-1.06) were independently associated with two or more nocturia episodes per night. No baseline factors predicted future development of nocturia (save for age, in one model). CONCLUSION: Hypertension, older age, and diuretic use were independently associated with two or more episodes of nocturia in cross-sectional analysis. No baseline factor was related to the development of nocturia over a 2-year interval in this sample. Nighttime fluid intake and coffee intake, practices providers commonly target in patients with nocturia, were not associated with nocturia in this population-based sample of community-living older adults.

The impact of own and spouse's urinary incontinence on depressive symptoms.

This study investigated the impact of own and spouse's urinary incontinence on depressive symptoms. Attention was paid to the possibility that gender and caregiving might be important factors in understanding significant effects. We used negative binomial regression to analyze survey data for 9974 middle-aged and older respondents to the Health and Retirement Study in the USA. Results supported the hypothesis that the respondents' own urinary incontinence was associated with depressive symptoms (unadj. IRR = 1.73, 95% CIs = 1.53, 1.95 for men; unadj. IRR = 1.50, 95% CIs = 1.38, 1.63 for women). Controlling sociodemographic and health variables reduced this relationship, but it remained statistically significant for both men and women. Having an incontinent wife put men at greater risk for depressive symptoms (unadj. IRR = 1.13, 95% CIs = 1.02, 1.25), although this relation became nonsignificant with the addition of control variables. No relation between women's depressive symptoms and husbands' (in)continence status was found. Caregiving was not a significant variable in the adjusted analyses, but spouses' depressive symptoms emerged as a significant predictor of the respondents' own depressive symptoms. Health care providers must be sensitive to the emotional impact of urinary incontinence. Our findings also suggest the importance of considering the patient's mental health within a wider context, particularly including the physical and mental health of the patient's spouse.

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.

Medical and self-care practices reported by women with urinary incontinence.

OBJECTIVES: To determine the extent to which women with incontinence have been identified by physicians, the coping and treatment strategies that incontinent women use, and the factors associated with treatment strategy utilization. STUDY DESIGN: A 2-stage, nationwide, cross-sectional survey. METHODS: Survey participants were adult women from representative US households in NFO WorldGroup survey panels. Of 2310 incontinent women who received the second-stage detailed questionnaire, 1970 (85%) responded. Descriptive analyses were performed to determine the impact of incontinence, the proportion of respondents who had talked to a physician about incontinence, the responses of physicians to these incontinent women, and coping strategies used. We conducted logistic regressions to determine factors associated with treatment strategy utilization. RESULTS: Almost half of incontinent women considered their incontinence moderately to extremely bothersome, yet only 56% of the moderately to extremely bothered women had ever talked to a physician about incontinence. In 85% of all cases, the incontinent woman, rather than the physician, raised the issue of incontinence. Coping strategies women reported ever trying included limiting fluid intake (38%) and physical activity (21%). Kegel exercises and prescription medications were used currently by 20% and 6% of this population, respectively. CONCLUSIONS: Among women of all ages, only about half of women bothered by incontinence have ever talked to a physician about it, and many incontinent women rely on strategies to avoid or conceal incontinence. A better understanding of the current use of coping and treatment strategies as well as the interaction between women and physicians regarding incontinence may help to inform efforts to optimize management of incontinence for women bothered by incontinence symptoms.

Patterns of body weight in middle-aged and older Americans, by gender and race, 1993-2000.

OBJECTIVES: Despite evidence of poor health outcomes associated with excessive weight gain or loss, longitudinal patterns of body weight over the adult life course have not been fully described. This article seeks to address this by examining body weight patterns for middle-aged and older adults. METHODS: Panel data from the Health and Retirement Study (HRS) original cohort and the original cohort of the Asset and Health Dynamics Among the Oldest Old (AHEAD) study are used to compare, by social group, characteristics of respondents and non-respondents, baseline weight (1993 and 1994) to year 2000 weight, and explore various weight change trajectories over time. RESULTS: Overall, a greater proportion of middle-aged adults are heavier over time than at baseline and a greater proportion of older adults lose weight over time compared to baseline. Examining the transitions across weight trajectories for all of the social groups suggests considerable variability. CONCLUSIONS: These findings suggest that differing physiologic and social or environmental experiences may have implications for body weight patterns. Understanding these patterns by race/ethnicity and gender could provide insight into health disparities among different social groups.

Proceedings of the National Institute of Diabetes and Digestive and Kidney Diseases International Symposium on Epidemiologic Issues in Urinary Incontinence in Women.

The Epidemiologic Issues in Urinary Incontinence: Current Databases and Future Collaborations Symposium included an international group of 29 investigators from 10 countries. The purpose of the symposium was to discuss the current understanding and knowledge gaps of prevalence, incidence, associated risk factors, and treatment outcomes for incontinence in women. During the symposium, investigators identified existing large databases and ongoing studies that provide substantive information on specific incontinence research questions. The investigators were able to form an international collaborative research working group and identify potential collaborative projects to further research on the epidemiology of urinary incontinence and bladder dysfunction.

Burden of stress urinary incontinence for community-dwelling women.

OBJECTIVE: The purpose of this study was to better understand the subjective bothersomeness of stress urinary incontinence symptoms and their impact on the quality of life of community-dwelling women. STUDY DESIGN: We conducted a mail survey of 605 women in the United States who reported symptoms of stress urinary incontinence. RESULTS: More than three fourths of the respondents reported their symptoms to be bothersome, with approximately 29% reporting their symptoms to be moderately to extremely bothersome. The odds of moderate-to-extreme bother decreased with age and increased with symptom severity. Concerns about social embarrassment were evident. CONCLUSION: Stress urinary incontinence symptoms can impose a significant burden on the women who have them. The results reinforce the need for health care professionals to be proactive in questioning and educating patients about this common lower urinary tract symptom.

Factors associated with women's decisions to seek treatment for urinary incontinence.

BACKGROUND: Urinary incontinence is a highly prevalent and burdensome condition among women. However, fewer than half of women with symptoms talk to a physician about incontinence, and the determinants of treatment seeking are not well understood. DESIGN: A two-stage cross-sectional survey of adult U.S. women; 45,000 households participating in NFO Worldgroup survey research received a questionnaire to identify adults with incontinence. Based on stratified random sampling of identified incontinent women, 2310 women received a detailed questionnaire. RESULTS: Among 1970 women with urinary incontinence symptoms, 38% had initiated a conversation with a physician about incontinence. In multivariate logistic regression analysis, some of the factors associated significantly with treatment seeking were symptom duration >3 years (OR 2.33, 95% CI 1.57-3.45), having a history of a noticeable accident (OR 1.41, 95% CI 1.06-1.87), worse disease-specific quality of life scores (OR 1.89, 95% CI 1.32-2.70), not being embarrassed to talk with a physician about urinary symptoms (OR 1.65, 95% CI 1.28-2.14), talking with others about urinary incontinence (OR 3.34, 95% CI 2.49-4.49), and keeping regular appointments for routine/preventive care (OR 2.25, 95% CI 1.54-3.29). CONCLUSIONS: Less than half of community-dwelling adult U.S. women with symptoms of urinary incontinence have talked with a physician about urinary incontinence. In addition to duration of symptoms, factors associated with treatment seeking included the impact of incontinence on quality of life, lack of embarrassment about talking to a physician about urinary symptoms, and attitudes toward healthcare use. Concerns about the meaning of incontinence for overall and future health were important reasons for women choosing to seek treatment.

Additive and interactive effects of comorbid physical and mental conditions on functional health.

OBJECTIVE: To understand the role of cognitive impairment and depressive symptoms on functional outcomes of stroke and diabetes. Evaluation approaches to functional outcomes have rarely focused on the presence of specific comorbidities, particularly those involving mental health disorders. METHODS: Data are from the AHEAD cohort of the Health and Retirement Study (HRS), a nationally representative panel of persons 70+ years of age in 1993. Analyses are limited to 5,646 self-respondents for whom functional outcome data are available in 1995. Additive and interactive multiple regression models are compared for each outcome and focal condition combination. RESULTS: The additive model is sufficient for the majority of outcome and focal condition combinations. The interaction term is significant in 4 of 12 comparisons. DISCUSSION: Stroke, diabetes, cognitive impairment, and depressive symptoms exhibit strong independent effects on physical functioning. Support for the hypothesis that cognitive impairment and depression exacerbate the impact of stroke and diabetes is more limited.

Informal caregiving time and costs for urinary incontinence in older individuals in the United States.

OBJECTIVES: To obtain nationally representative estimates of the additional time, and related cost, of informal caregiving associated with urinary incontinence in older individuals. DESIGN: Multivariate regression models using data from the 1993 Asset and Health Dynamics Study, a nationally representative survey of people aged 70 and older (N = 7,443). SETTING: Community-dwelling older people. PARTICIPANTS: National population-based sample of community-dwelling older people. MEASUREMENTS: Weekly hours of informal caregiving, and imputed cost of caregiver time, for community-dwelling older people who reported (1) no unintended urine loss, (2) incontinence that did not require the use of absorbent pads, and (3) incontinence that required the use of absorbent pads. RESULTS: Thirteen percent of men and 24% of women reported incontinence. After adjusting for sociodemographics, living situation, and comorbidities, continent men received 7.4 hours per week of care, incontinent men who did not use pads received 11.3 hours, and incontinent men who used pads received 16.6 hours (P <.001). Women in these groups received 5.9, 7.6, and 10.7 hours (P <.001), respectively. The additional yearly cost of informal care associated with incontinence was $1,700 and $4,000 for incontinent men who did not and did use pads, respectively, whereas, for women in these groups, the additional yearly cost was $700 and $2,000. Overall, this represents a national annual cost of more than $6 billion for incontinence-related informal care. CONCLUSIONS: The quantity of informal caregiving for older people with incontinence and its associated economic cost are substantial. Future analyses of the costs of incontinence, and the cost-effectiveness of interventions to prevent or treat incontinence, should consider the significant informal caregiving costs associated with this condition.
