The Behavior Change Consortium: setting the stage for a new century of health behavior-change research.

The Behavior Change Consortium (BCC), a collective of 15 National Institutes of Health-funded behavior-change projects, was conceived with the goal of evaluating the efficacy and effectiveness of novel ways of intervening in diverse populations to reduce tobacco dependence, and improve physical activity, nutrition and other health behaviors. The purpose of this article is to provide a general introduction and context to this theme issue by: (1) reviewing the promises and challenges of past efforts related to promoting change for three key health behaviors; (2) reviewing successful intervention strategies and principles of health behavior change; (3) discussing major theoretical approaches for obtaining successful behavior change; (4) setting BCC activities within the context of recent recommendations for the behavioral and social sciences; and (5) providing an organizational framework for describing each of the projects within this consortium. In addition to the rich database on behavioral outcomes for tobacco dependence, physical activity and diet, the BCC represents a unique opportunity to share data and address cross-cutting intervention research issues critical for strengthening the field of behavior change research.

The effects of exercise on the quality of life of frail older adults: a preplanned meta-analysis of the FICSIT trials.

The Frailty and Injuries: Cooperative Studies of Intervention Techniques (FICSIT) was a linked series of randomized clinical trials focused on the benefits of exercise in the frail elderly. This article uses covariate-adjusted preplanned meta-analyses of FICSIT data to evaluate the effect of exercise on quality of life (QOL) outcomes (N = 1,733; age = 73.4 +/- 6.1 years). Results indicate that (a) exercise produced a small but significant improvement in the emotional health component of QOL, trended toward an improved social component, and did not effect perceptions of general health; (b) exercise-related joint and muscle stresses did not increase bodily pain; and (c) QOL improvements were independent of changes in physical functioning. We conclude that exercise can improve QOL in the frail elderly but that the magnitude of the improvement is modest in size. The benefits of a meta-analytical approach for documenting efficacy outcomes across different types of interventions are discussed.

Targeted mailed materials and the Medicare beneficiary: increasing mammogram screening among the elderly.

OBJECTIVES: Older women have the highest breast cancer rates but are underscreened relative to their risk. Racial/ethnic minority women especially have low screening rates, often because of financial constraints. In response, Medicare introduced subsidized biennial mammogram benefits in 1991. This study examined the effect on mammography rates of an intervention that informed women about the Medicare benefit. METHODS: A list frame method of subject selection was used to select random samples of eligible women from the Health Care Financing Administration's master beneficiary file. Women were interviewed by telephone in 1991 (N = 917) before the targeted mailing and in 1993 (N = 922). One control and 2 treatment communities participated. RESULTS: Mammogram use increased significantly among minorities in the treatment groups. Among minorities who received the intervention, Black women were twice as likely (odds ratio = 1.97) and Hispanic women were more than twice as likely (odds ratio = 2.33) to undergo screening relative to their untreated cohorts. CONCLUSIONS: A targeted low-cost mailed intervention can help increase screening rates among elderly minority women. The Health Care Financing Administration should promote its benefits aggressively if it expects to reach its target--elderly beneficiaries.

Communication between older patients and their physicians.

This article provides an overview of communication between older patients and their physicians. The authors discuss distinctive features of geriatric medical visits and empirical investigations of communication between physicians and older patients in real life clinical encounters highlighting the content, interactional processes, and outcomes of care. They also discuss strategies for improving communication between physicians and older patients using new and innovative technologies. The authors conclude that healing in its broadest sense can occur only through a humanistic approach to geriatric care.

The economic implications of self-care: the effect of lifestyle, functional adaptations, and medical self-care among a national sample of Medicare beneficiaries.

OBJECTIVES: Self-care includes actions taken by individuals to promote or ensure their health, to recover from diseases or injuries, or to manage their effects. This study measured associations between self-care practices (lifestyle practices, adaptations to functional limitations, and medical self-care) and Medicare expenditures among a national sample of adults 65 years and older. METHODS: Regression models of Medicare use and expenditures were estimated by using the National Survey of Self-Care and Aging and Medicare claims for 4 years following a baseline interview. RESULTS: Lifestyle factors (swimming and walking) and functional adaptations (general home modifications) were associated with reductions in monthly Medicare expenditures over a 12-month follow-up period. Expenditure reductions were found over the 48-month follow-up period for participation in active sports, gardening, and medical self-care. Practices associated with increases in expenditures included smoking, physical exercise (possibly of a more strenuous nature), and specific home modifications. CONCLUSIONS: Certain self-care practices appear to have significant implications for Medicare expenditures and presumptively for the health status of older adults. Such practices should be encouraged among older adults as a matter of national health policy.

Prevalence and impact of caregiving: a detailed comparison between dementia and nondementia caregivers.

Analyzing data from more than 1,500 family caregivers from the 1996 National Caregiver Survey, this study documents the ways in which dementia care is different from other types of family caregiving. Not only do dementia caregivers spend significantly more hours per week providing care than nondementia caregivers, they also report greater impacts in terms of employment complications, caregiver strain, mental and physical health problems, time for leisure and other family members, and family conflict. Differential impacts remain even after controlling for intensity of caregiving involvement and sociodemographic factors. Study findings suggest the need to tailor programs and services to the unique challenges faced by dementia caregivers.

Quality of life following bladder training in older women with urinary incontinence.

This study investigated the changes in quality of life following a randomized controlled 6-week trial of bladder training in 123 older women with urinary incontinence. Both clinical (diary, pad test) and quality of life measures (Incontinence Impact Questionnaire (IIQ), Center for Epidemiological Studies-Depression Scale (CES-D)) and visual analog scales on symptom burden were obtained at baseline, 6 weeks and 6 months following treatment. All subscales and the composite scale of the IIQ and the visual analog scales were significantly improved following bladder training, with effects maintained 6 months later. No changes were observed in CES-D scores. Women with genuine stress incontinence and those with detrusor instability with or without concomitant stress incontinence had similar improvements. We conclude that bladder training is effective in improving the quality of life of incontinent women regardless of urodynamic diagnosis.

Gender, self-reported depressive symptoms, and sleep disturbance among older community-dwelling persons. FICSIT group. Frailty and Injuries: Cooperative Studies of Intervention Techniques.

The purposes of this report are: (1) to investigate the association between sleep disturbances and depressive symptomatology in older adults; (2) to evaluate the degree to which gender serves to mediate this relationship; and (3) to determine whether several predefined covariates help to explain the association between sleep disturbance and depressive symptoms. This is a retrospective and cross-sectional analysis of baseline data from 485 elderly adults enrolled in three of the eight clinical sites participating in the Frailty and Injuries: Cooperative Studies of Intervention Techniques (FICSIT) trials. FICSIT was a linked series of randomized clinical trials which evaluated the impact of various exercise interventions on several measures of frailty in older adults. Women reported more depressive symptoms and more sleep disturbances than men. Sleep disturbances were independently associated with depressive symptoms, bodily pain, a history of falling, limited education, being married, and being female. Gender interactions suggest that, although women reported more depressive symptoms and more chronic health conditions than men, both may be more important predictors of sleep disturbance in men. By contrast, being married may be more predictive in women. Finally, the data suggest a stronger relationship between sleep disturbance and depressive symptoms in men than in women.

Predicting mortality from community surveys of older adults: the importance of self-rated functional ability.

Using data from the 1990 baseline of the National Survey of Self-Care and Aging (NSSCA), and nearly three years of follow-up mortality data, we examined the association between self-rated functional ability, a global measure of perceived ability of function independently, and mortality among a national sample of older adults. The study included 3,485 subjects selected from the Medicare Beneficiary Files according to a stratified random sampling design, with approximately equal numbers of adults by gender in each of three age categories, 65-74, 75-84, and 85 and over. Self-rated functional ability was found to have an independent contribution to the subsequent risk of death among older adults. Using multivariate models that accounted for self-rated health, age, gender, medical conditions, functional status, and assistance from others, poor self-ratings on this single item nearly doubled the risk of death during the follow-up period. These findings suggest the importance, for both researchers and clinicians, of measuring the potential prognostic importance of self-ratings of health and self-ratings of functional ability among older adults.

Metropolitan versus nonmetropolitan differences in functional status and self-care practice: findings from a national sample of community-dwelling older adults.

The objective of this study was to use a recent national probability survey of the noninstitutionalized older adult population to compare the functional status and self-care practices of older adults residing in metropolitan and nonmetropolitan communities and to identify differences associated with residential location. The survey used in this study was the National Survey of Self-care and Aging (NSSCA). A cross-sectional design was employed using weighted bivariate and multivariate logistic regression analyses to examine the relationship between metropolitan and nonmetropolitan residential location and self-reported ability to perform basic, mobility, and instrumental activities of daily living (ADLs), as well as to assess the degree to which the levels and types of functional limitations affect metropolitan versus nonmetropolitan older adults' performance of self-care activities. The bivariate logistic analyses pointed to modest, often insignificant metropolitan versus nonmetropolitan differences in the ability to perform functional tasks. However, larger positive effects of nonmetropolitan residence were generally observed once other factors likely to account for some of these differences were taken into account. Older adults from nonmetropolitan areas were more likely to report being able to perform functional activities but also were more likely to report performing self-care activities both in the presence and absence of disability. This study, therefore, concluded that nonmetropolitan older adults may discount the significance of declining functional status, thus normalizing the trajectory of aging in a different way than do their metropolitan counterparts. If this process occurs, it may affect how nonmetropolitan persons use primary health care and/or long-term care services, challenging the economists' concept of demand, the clinicians' concept of need, and the policy analysts' concept of equity. Additional work is required to assess whether such a normalization process actually occurs and, if so, to explore its distribution, causes, correlates, and consequences.

Older adults as a community resource: results from the National Survey of Self-Care and Aging.

Using data collected from the first wave of a longitudinal data set collected in the late fall and winter of 1990-1991, the National Survey of Self-Care and Aging (NSSCA), we examined the extent and type of assistance older people provided to others. Age, gender, and perceived health status were the most consistent predictors of the four types of assistance: personal care, child care, volunteer work, and listening/offering advice and support. Help with instrumental activities of daily living either alone or in combination with other activities of daily living was the most common type of personal care provided.

The effects of exercise on falls in elderly patients. A preplanned meta-analysis of the FICSIT Trials. Frailty and Injuries: Cooperative Studies of Intervention Techniques.

OBJECTIVE: To determine if short-term exercise reduces falls and fall-related injuries in the elderly. DESIGN: A preplanned meta-analysis of the seven Frailty and Injuries: Cooperative Studies of Intervention Techniques (FICSIT)--independent, randomized, controlled clinical trials that assessed intervention efficacy in reducing falls and frailty in elderly patients. All included an exercise component for 10 to 36 weeks. Fall and injury follow-up was obtained for up to 2 to 4 years. SETTING: Two nursing home and five community-dwelling (three health maintenance organizations) sites. Six were group and center based; one was conducted at home. PARTICIPANTS: Numbers of participants ranged from 100 to 1323 per study. Subjects were mostly ambulatory and cognitively intact, with minimum ages of 60 to 75 years, although some studies required additional deficits, such as functionally dependent in two or more activities of daily living, balance deficits or lower extremity weakness, or high risk of falling. INTERVENTIONS: Exercise components varied across studies in character, duration, frequency, and intensity. Training was performed in one area or more of endurance, flexibility, balance platform, Tai Chi (dynamic balance), and resistance. Several treatment arms included additional nonexercise components, such as behavioral components, medication changes, education, functional activity, or nutritional supplements. MAIN OUTCOME MEASURES: Time to each fall (fall-related injury) by self-report and/or medical records. RESULTS: Using the Andersen-Gill extension of the Cox model that allows multiple fall outcomes per patient, the adjusted fall incidence ratio for treatment arms including general exercise was 0.90 (95% confidence limits [CL], 0.81, 0.99) and for those including balance was 0.83 (95% CL, 0.70, 0.98). No exercise component was significant for injurious falls, but power was low to detect this outcome. CONCLUSIONS: Treatments including exercise for elderly adults reduce the risk of falls.

Self-care and assistance from others in coping with functional status limitations among a national sample of older adults.

Using data from the first wave of a new longitudinal data set collected in the late fall and winter of 1990-1991, the National Survey of Self-Care and Aging (NSSCA), we examined older adults' self-care practices in coping with functional status limitations based on in-person interviews with a national probability sample of 3,485 noninstitutionalized adults aged 65 or older selected from Medicare beneficiary files. A composite score of functional status was calculated to reflect the presence and severity of disability in three dimensions: basic, mobility, and instrumental activities of daily living. Three types of self-care coping strategies were defined: use of equipment or devices, changes in behavior, and modifications in one's environment. National estimates of self-care practices, assistance from others, and functional status measures were presented. Data revealed that the likelihood of engaging in self-care coping strategies increased as the severity of disability increased, except among the most severely disabled. Generally, those receiving assistance from others were more likely to engage in self-care activities, suggesting that receiving assistance supplements, rather than supplants, self-care coping strategies.

Preventing falls among community-dwelling older persons: results from a randomized trial.

A randomized trial of falls prevention program that addressed home safety, exercise, and behavioral risks was conducted with 3,182 independently living HMO members age 65 and older. The intervention decreased the odds of falling by 0.85, but only reduced the average number of falls among those who fell by 7%. The effect was strongest among men age 75 and older. The likelihood of avoiding falls requiring medical treatment was not significantly affected by the intervention. We conclude that the intervention dose was not of sufficient intensity or duration to have a marked protective effect on older persons. Future research should focus on more intensive intervention approaches because serious falls do not appear to be amendable to low-intensity environment/behavioral efforts.
