Changes in health behaviors of older adults: the San Diego Medicare Preventive Health Project

Behaviour change techniques in personalised care planning for older people: a systematic review

BACKGROUND

Personalised care planning (PCP) interventions have the potential to provide better outcomes for older people and are a key focus in primary care practice. Behaviour change techniques (BCTs) can maximise effectiveness of such interventions, but it is uncertain which BCTs are most appropriate in PCP for older adults.

AIM

To identify BCTs used in successful PCP interventions for older people aged ≥65 years.

DESIGN AND SETTING

Systematic review.

METHOD

The authors searched 12 databases from date of inception to 30 September 2017. They identified randomised controlled trials (RCTs) of interventions involving participants aged ≥65 years, and contextually related to PCP. Five areas of risk of bias were assessed. The Michie et al, BCT taxonomy was used for coding.

RESULTS

Twenty-three RCTs involving 6489 participants (average age 74 years) described PCP interventions targeting the general older adult population and older people with specific long-term conditions (for example, heart disease, diabetes, stroke). Just over half of the studies were deemed to be at a low risk of bias. Eleven 'promising' BCTs were identified in five trials reporting significant improvements in quality of life (QoL). Six BCTs were reported in all five of these trials: 'goal setting', 'action planning', 'problem solving', 'social support', 'instructions on how to perform a behaviour', and 'information on health consequences'. Modes of delivery varied.

CONCLUSION

Future PCP interventions to improve QoL for people aged ≥65 years may benefit from focusing on six specific BCTs. Better reporting of BCTs would enhance future design and implementation of such interventions.

Health Risk Appraisals With Aging Adults: An Integrative Review

Identification of risk factors unique to the aging experience is vital to support health promotion efforts and prevent loss of independence for the increasing aging population. Health risk appraisals are tools capable of identifying a broad range of factors that affect health; however, these tools were designed for use with predominantly healthy working-age adults. The purpose of this integrative review was to describe uses and adaptations of health risk appraisals with aging adults. A total of 43 articles met inclusion criteria, identifying multiple adaptations necessary to effectively identify the risks faced by aging adults, including those related to activities of daily living, pain, depression, social support/network, vision, hearing, and cognitive status. Uses included support for health promotion efforts and to determine risk for depression, falls, and loss of independence. Further research needs to be done to evaluate impact when used as a health promotion and prevention tool for aging adults.

The STAYWELL Program-Maximizing Elders' Capacity for Independent Living Through Health Promotion and Disease Prevention Activities

The STAYWELL Program, an 8-session health promotion/disease prevention pro-gram for older adults, was found to have a significant impact on elder participants' health-related beliefs and behaviors. This quasi-experimental study's 146 participants were recruited from 8 western New York senior citizen centers, and 70% (n = 102) were available for a 9-month follow-up assessment. As compared with elders on a waiting list, study participants who experienced the STAYWELL intervention ex-pressed significantly healthier beliefs and reported behavioral changes indicative of a healthier lifestyle at follow-up. All of the intervention effect sizes observed may be characterized as large to very large: (1) The intervention group expressed healthier beliefs as assessed using the healthy belief index-at follow-up, three quarters of them scored higher on this measure than the average person in the waiting list comparison group (U3 = 77.3%); (2) the intervention group engaged in healthier behaviors as assessed by using the healthy behavior index (U3 = 92.4%); and (3) they also took fewer medications (U3 = 74.2%); all p < .05. Extant cohorts in this field (more than 20,000 elders) may offer collaborative opportunities for needed longer follow-up of health outcome end-points.

Relationship of health locus of control with specific health behaviours and global health appraisal: a meta-analysis and effects of moderators

Health locus of control (HLOC) refers to beliefs regarding how one’s health is influenced by oneself, others, or fate. This meta-analysis investigated whether three HLOC dimensions (internality/I-HLOC, powerful others/P-HLOC, chance/C-HLOC) were related to both specific health behaviours and global health appraisal, and whether these relationships were moderated by gender and age compositions, individualism, and power distance. Three-level mixed-effects meta-analysis was performed on studies examining the associations of HLOC with specific health behaviour (k = 76, N = 76,580, 57% women, M_age = 43.75) and global health appraisal (k = 95, N = 12,068, 57% women, M_age = 45.44), respectively. For specific health behaviour, the averaged correlations with the HLOC dimensions were generally weak (r’s = −.07 to .10). However, the links between P-HLOC and exercise were moderated by all four demographic moderators, and gender composition and individualism moderated the association between the HLOC dimensions and diet. For global health appraisal, all of the averaged correlations were statistically significant (r’s = −.16 to .21), except that between P-HLOC and mental quality of life. The results further showed individualism and power distance to moderate the links between the HLOC dimensions and both mental and physical quality of life, and gender composition to moderate those between these dimensions and two indicators of emotional problems (depression and anxiety).

Intervening on Exercise and Nutrition in Older Adults

Presented are the basic design, methods, and baseline data analyses for the Study of Exercise and Nutrition in Older Rhode Islanders (SENIOR Project) an experimental study to investigate the relative effectiveness of a 12-month, stage of readiness to change-based multiple-behavior intervention (exercise and nutrition) compared to single-behavior interventions in a community-dwelling population of 1,277 older adults. Relationships between stage of readiness to change in the two target behaviors, as well as the relationship between stage of readiness and self-reported exercise levels and fruit and vegetable consumption, were examined using a combination of Pearson chi-squares, analyses of variance (ANOVA), and Spearman’s rank order correlations. Stage of change (SOC) for fruit and vegetable consumption was significantly associated with the dietary measure, and SOC for exercise was associated with both the three physical activity measures and servings of fruits and vegetables per day. Overall, individual older adult's readiness to change seems largely to be behavior-specific.

The Development and Efficacy of a Theory-Based Educational Curriculum to Promote Self-Regulation Among High-Risk Older Drivers

Knowledge Enhances Your Safety (KEYS) is a curriculum developed for older drivers who maintain driving privileges while coping with visual limitations that increase crash risk. KEYS’ goal is to promote safe driving through self-awareness of vision impairment and adopting self-regulatory strategies. We discuss KEYS’ theoretical framework based on the tenants of the Social Cognitive Theory, Health Belief and Transtheoretical Models, and Principles of Self-Regulation and Regulatory Self-Efficacy. Baseline and 6-month posttest evaluations tested its efficacy in terms of theoretical construct outcomes. KEYS’ participants improved self-perceptions of vision impairment, perceived a greater number of benefits in the performance of self-regulatory behaviors, and moved closer to the preparation and action/maintenance stages of change. Results indicate that high-risk older drivers benefit from educational interventions that promote self-awareness and self-regulation of driving. Future work will evaluate KEYS’ efficacy for high-risk older drivers in promoting driver behavior changes and its impact on crash involvement.

Prevalence and Correlates of Exercise Among Older Adults

A secondary analysis of data from the 1990 Health Promotion and Disease Prevention Supplement to the National Health Interview Survey was conducted to estimate the prevalence of exercise among adults aged 55 and older and identify correlates of exercise in this population. Walking and participation in other exercises were the exercise variables, and the explanatory variables included sociodemographic measures, self-reported health status and medical conditions, and health belief measures. For both exercise measures, physical activity declined with advanced age. Age, gender, education, and the health beliefs that smoking causes heart disease and cancer were the most important correlates of walking and playing sports. Additional interventions are needed to increase participation in regular walking, the most prevalent form of physical activity among older adults. In developing and testing these strategies, investigators should place emphasis on an approach that incorporates health education rather than simple prescriptive advice regarding regular exercise.

Effects of a one-year physical activity programme for women with systemic lupus erythematosus - a randomized controlled study

OBJECTIVES

To study the effects of a one-year physical activity programme on aerobic capacity, physical activity and health-related quality of life (HRQL) in patients with systemic lupus erythematosus (SLE) by a randomized control design.

METHODS

Thirty-five women with low or moderate disease activity and organ damage were randomized to intervention (I) or control (C) group. The intervention during months 0-3 consisted of education, supervised aerobic exercise at high intensity and individual coaching, as well as self-managed physical activity at low-to-moderate intensity. During months 4-12, the physical activity was self-managed and the coaching was successively reduced over time. Outcome measures included: maximal oxygen uptake (VO2 max) from a bicycle ergometer test, self-reported physical activity and HRQL (SF-36).

RESULTS

VO2 at sub-max. and max. increased, independent of group, during the one-year study period (main effect of time p < 0.0001). VO2 max. increased between baseline and month 3 (p < 0.0001), between months 3 and 6 (p = 0.01) and the increase was sustained at month 12 (ns). Frequency of physical activity at high intensity also increased, independent of group, during the study period. It was increased at months 3, 6 and 12 compared to baseline (p = 0.02, p < 0.001, p = 0.03). Improvement in mental health between baseline and month 6 (p = 0.002) was seen for the I-group, not the C-group (p = 0.03). Disease activity and organ damage did not change.

CONCLUSIONS

Physical activity and aerobic capacity increased after supervised exercise and coaching, and the improvement was sustained during the one-year programme. However, no interactions between the group differences were seen, which suggests that repeated measurements could motivate to increased physical activity and thereby to increased aerobic capacity. As sub-max. VO2 increased over time, training-induced changes in VO2 on-kinetics could be another explanation. Little influence on HRQL was seen after the programme. The study indicates that physical activity at high intensity over one year is tolerated by patients with mild to moderate SLE.

Systematic literature review of randomized control trials assessing the effectiveness of nutrition interventions in community-dwelling older adults

OBJECTIVE

Nutrition interventions may play an important role in maintaining the health and quality of life in community-dwelling older adults. To the authors' knowledge, no systematic literature review has been conducted on the effectiveness of nutrition interventions in the community-dwelling older adult population.

DESIGN

Systematic literature review followed by descriptive data extraction and critical appraisals for studies meeting inclusion criteria.

SETTING

Medical Literature and Retrieval System Online (MEDLINE) and Cumulative Index to Nursing and Allied Health Literature (CINAHL) search for randomized controlled trials (RCTs) assessing nutrition interventions in community-dwelling older adults.

PARTICIPANTS

Fifteen RCTs involving nutrition-related outcomes in community-dwelling older adults.

ANALYSIS

Descriptive data extraction and critical appraisals using the Jaded scale. Outcome measures included study blinding, allocation concealment, intention-to-treat analysis, and a priori calculations.

RESULTS

Ten RCTs involved nutrition counseling, education, or dietary advice, whereas 5 involved nutrition supplements. Jaded scores ranged from 1 (n = 8) to 2 (n = 4) to 4 (n = 3). Ten RCTs reported positive results post-intervention.

CONCLUSIONS AND IMPLICATIONS

Nutrition counseling interventions involving active participation and collaboration showed the most promise in affecting positive nutrition-related outcomes in community-dwelling older adults. Future research should determine which nutrition interventions will benefit community-dwelling older adults with less active participation and health perceptions, and lower educational attainment.

Maintaining exercise and healthful eating in older adults: the SENIOR project II: study design and methodology

The Study of Exercise and Nutrition in Older Rhode Islanders (SENIOR) Project II is an intervention study to promote the maintenance of both exercise and healthful eating in older adults. It is the second phase of an earlier study, SENIOR Project I, that originally recruited 1277 community-dwelling older adults to participate in behavior-specific interventions designed to increase exercise and/or fruit and vegetable consumption. The general theoretical framework for this research is the Transtheoretical Model (TTM) of Health Behavior Change. The current intervention occurs over a 48-month period, using a manual, newsletters, and phone coaching calls. Annual assessments collect standardized data on behavioral outcomes (exercise and diet), TTM variables (stage of change and self-efficacy), psychosocial variables (social support, depression, resilience, and life satisfaction), physical activity and functioning (SF-36, Up and Go, Senior Fitness Test, and disability assessment), cognitive functioning (Trail Making Test and Forward and Backward Digit Span), physical measures (height, weight, and waist circumference), and demographics. The SENIOR Project II is designed to answer the following question as its primary objective: (1) Does an individualized active-maintenance intervention with older adults maintain greater levels of healthful exercise and dietary behaviors for 4years, compared to a control condition? In addition, there are two secondary objectives: (2) What are the psychosocial factors associated with the maintenance of health-promoting behaviors in the very old? (3) What are the effects of the maintenance of health-promoting behaviors on reported health outcomes, psychosocial measures, anthropometrics, and cognitive status?

Efeito do exercício físico aeróbio sobre o perfil lipídico de pacientes idosas, portadoras de Diabetes Mellitus tipo 2, atendidas em Unidade Básica de Saúde, Maringá, Estado do Paraná

RESUMO Este estudo tem por objetivo verificar a influência de um programa de exercícios físicos aeróbios sobre o perfil lipídico de pacientes idosas, portadoras de Diabetes Mellitus (DM) tipo 2. Foram selecionados 40 pacientes do gênero feminino com idade maior ou igual a 60 anos. A amostra foi distribuída em dois grupos de 20 pacientes cada: Grupo Treinado, que recebeu orientação nutricional e participou das sessões supervisionadas de exercício físico aeróbio, e Grupo Controle, que recebeu somente orientação nutricional. A intervenção teve a duração de 12 semanas. O protocolo de exercício foi aplicado três vezes por semana, tendo cada sessão 1 h de duração. Os dados obtidos mostraram que o protocolo desenvolvido promoveu redução significativa nos triglicerídeos séricos (pré-teste= 190 ± 76,67 e pós-teste= 125,33 ± 45,82 mg/dL, p<0,05) e no LDL-colesterol (pré-teste= 147,98 ± 29,98 e pós-teste= 122,24 ± 17,61 mg/dL, p<0,05) no Grupo Treinado. Os resultados permitiram concluir que o programa de exercícios adotado promoveu melhora no perfil lipídico de pacientes idosas portadoras de DM tipo 2, demonstrando a importância da prática de atividade física orientada em Unidades Básicas de Saúde.

Older adults' exercise behavior: roles of selected constructs of social-cognitive theory

Exercise is consistently related to physical and psychological health benefits in older adults. Bandura's social-cognitive theory (SCT) is one theoretical perspective on understanding and predicting exercise behavior. Thus, the authors examined whether three SCT variables-self-efficacy, self-regulation, and outcome-expectancy value-predicted older adults' (N = 98) exercise behavior. Bivariate analyses revealed that regular exercise was associated with being male, White, and married; having higher income, education, and self-efficacy; using self-regulation skills; and having favorable outcome-expectancy values (p < .05). In a simultaneous multivariate model, however, self-regulation (p = .0097) was the only variable independently associated with regular exercise. Thus, exercise interventions targeting older adults should include components aimed at increasing the use of self-regulation strategies.

Which model of successful ageing should be used? Baseline findings from a British longitudinal survey of ageing

BACKGROUND

there is increasing interest in how to age 'successfully' and in reaching consensus over its definition.

OBJECTIVE

to assess different models of successful ageing, using a British longitudinal survey of ageing in 2000-1.

SETTING

community settings in Britain.

METHODS

five models of successful ageing were tested on a British cross-sectional population survey of 999 people aged 65+. The models were biomedical, broader biomedical, social, psychological and lay based.

RESULTS

the lay model emerged as the strongest. Respondents who were classified as successfully aged with this model, compared with those not successfully aged, had over five times the odds of rating their quality of life (QoL) as good rather than not good [odds ratio (OR) = 5.493, 95% confidence interval (95% CI) = 2.655-11.364].

CONCLUSION

the lay-based, more multidimensional, model of successful ageing predicted perceived QoL more powerfully than unidimensional models and should be used to evaluate the outcomes of health promotion in older populations.

[Analysis of the Educational Program for Self-Care in the Elderly (PECA) for improving the quality of life of the elderly]

OBJECTIVE

To determine the efficacy over 12 months of the educational programme on self-care of the elderly (PECA), which covers quality of life, nutritional status, and perceived social support of people over 65 living in their own homes.

DESIGN

Pre-test/post-test experimental study with control group.

SETTING

Urban population in the Manso Health District (Example, Barcelona), Spain.

PARTICIPANTS

Persons over 65 living in their own homes, healthy or with chronic illnesses characteristic of their age, who had a normal score in the Pfeiffer test. A total of 70 subjects (35 per group) were selected and 5 of the control group left the study.

INTERVENTION

Programme on self-care of the elderly, including education on physical activity, nutrition, and social support.

MEASUREMENTS

Dependent variables were quality of life, measured by the Nottingham Health Profile; nutritional status, measured by the Mini-Nutritional Assessment (MNA); and social support, measured by the Duke-Unk Functional Social Support Scale.

RESULTS

The study sample had an average age of 70.9 (SD, 3.1); 88.2% had self-perception of good health; and 21% lived alone. We only found statistically significant differences between pre- and post-intervention observations in nutritional status (P=.001).

CONCLUSION

Despite a statistically significant difference in the variable of nutritional status, the difference was not "clinically" relevant. The ineffectiveness of the intervention is due to our starting from a very homogeneous sample, which had good health status and well-established social networks.

Health promotion behaviors and quality of life among community-dwelling elderly in Korea: A cross-sectional survey

As individuals live longer, health promotion behaviors become even more important, particularly with regard to maintaining functional independence and improving quality of life (QoL). The purpose of this study was to explore the relationship between health promotion behaviors and QoL in Korean elderly living in the community. This study was a descriptive-correlational study to explore the relationship between health promotion behaviors and QoL among the community-dwelling elderly in Korea. A convenience sample of 2000 community residents who were over 65 years old and cognitively intact were selected from 32 senior centers and 242 public health centers in Korea. A total of 1920 were included in the analyses, following the exclusion of 80 incomplete questionnaires and subject refusals. Participants who consented to participate in the study were interviewed by trained interviewers with a structured questionnaire. The results of the study showed that there were statistically significant differences in QoL of the elderly related to exercise participation, alcohol abstinence and blood pressure (BP) check-up (p<.05). Multiple regression analysis revealed that perceived health status, number of chronic illnesses, activities of daily living, BP checkup, exercise, and gender were statistically significant predictors of QoL. R(2) for this whole regression model was .412, indicating that approximately 41.2% of the variance in QoL was accounted for by the linear combination of these variables. Nurses should enhance the QoL in elderly persons by facilitating health promotion behaviors through formal nursing interventions which will maintain and increase a healthy and active life.

The routine use of health risk appraisals: results from a national study of physician organizations

PURPOSE

To document use of health risk appraisals (HRAs) by U.S. physician organizations as part of their overall approach to health promotion and to identify associated organizational characteristics.

METHODS

Telephone survey of 1590 physician organizations in the United States; surveys were conducted in organizations comprising 20 or more physicians and were conducted between September 2000 and September 2001 (70% response rate). Chi-square tests and logistic regression analysis were used to examine the association between organizational characteristics and routine administration of HRAs.

RESULTS

Only 22.5% of physician organizations in the United States routinely administer HRAs. External quality incentives, information technology capabilities, and status as a medical group vs. an independent practice association are associated with greater odds of the routine use of HRA.

DISCUSSION

Increased use of external quality incentives and information technology in physician organizations may be important in supporting the use of HRAs.

Efeitos de um programa de orientação de atividade física e nutricional sobre o nível de atividade física de mulheres fisicamente ativas de 50 a 72 anos de idade

A promoção do estilo de vida mais ativo na terceira idade tem sido utilizada como estratégia de desenvolver melhora nos padrões de saúde e na qualidade de vida. O objetivo do presente estudo foi verificar o efeito de um programa de orientação de atividade física (AF) e nutricional sobre o nível de atividade física (NAF) de mulheres fisicamente ativas. A amostra foi composta de 64 senhoras de 50 a 72 anos de idade de São Caetano do Sul que participavam de um programa regular de ginástica. As senhoras foram alocadas em um dos quatro grupos: A) nutrição (n: 17); B) nutrição + atividade física (n: 17); C) atividade física (n: 13); D) controle (n: 15). Para avaliar o NAF foi utilizado o Questionário Internacional de Atividade Física IPAQ. O programa de intervenção foi realizado durante 12 semanas, uma vez por semana, por 5 a 10 minutos após as aulas de ginástica. As orientações nutricionais foram baseadas na nutrição saudável e as de AF fundamentadas na mensagem do Agita São Paulo, que estimula, pelo menos 30 minutos por dia, na maior parte dos dias da semana, de forma contínua ou acumulada, atividades físicas em intensidade moderada, além das aulas de ginástica. Os resultados indicaram aumento na freqüência (vezes/semana) das atividades moderadas (32,4%; 49,6%; 47,9%; p < 0,05) nos grupos A, B e C, respectivamente, após 12 semanas de intervenção, em comparação com o controle. As senhoras que receberam orientação de AF aumentaram significativamente a duração das atividades moderadas em 123,2% e da caminhada em 150,9% e também a freqüência da caminhada (97,6%) em relação aos valores pré-intervenção. O presente estudo demonstrou que o programa de intervenção promoveu aumento significativo do NAF até mesmo em senhoras irregularmente ativas.

Goal setting as a strategy for dietary and physical activity behavior change: a review of the literature

OBJECTIVE

Estimate effectiveness of goal setting for nutrition and physical activity behavior change, review the effect of goal-setting characteristics on behavior change, and investigate effectiveness of interventions containing goal setting.

DATA SOURCE

For this review, a literature search was conducted for the period January 1977 through December 2003 that included a Current Contents, Biosis Previews, Medline, PubMed, PsycINFO, and ERIC search of databases and a reference list search. Key words were goal, goal setting, nutrition, diet, dietary, physical activity, exercise, behavior change, interventions, and fitness.

STUDY INCLUSION AND EXCLUSION CRITERIA

The search identified 144 studies, of which 28 met inclusion criteria for being published in a peer reviewed journal and using goal setting in an intervention to modify dietary or physical activity behaviors. Excluded from this review were those studies that (1) evaluated goal setting cross-sectionally without an intervention; (2) used goal setting for behavioral disorders, to improve academic achievement, or in sports performance; (3) were reviews.

DATA EXTRACTION AND SYNTHESIS

The articles were categorized by target audience and secondarily by research focus. Data extracted included outcome measure, research rating, purpose, sample, sample description, assignment, findings, and goal-setting support.

RESULTS

Thirteen of the 23 adult studies used a goal-setting effectiveness study design and eight produced positive results supporting goal setting. No adolescent or child studies used this design. The results were inconclusive for the studies investigating goal-setting characteristics (n = 7). Four adult and four child intervention evaluation studies showed positive outcomes. No studies reported power calculations, and only 32% of the studies were rated as fully supporting goal setting.

CONCLUSIONS

Goal setting has shown some promise in promoting dietary and physical activity behavior change among adults, but methodological issues still need to be resolved. The literature with adolescents and children is limited, and the authors are not aware of any published studies with this audience investigating the independent effect of goal setting on dietary or physical activity behavior. Although, goal setting is widely used with children and adolescents in nutrition interventions, its effectiveness has yet to be reported.

Health risk appraisal for older people in general practice using an expert system: a pilot study

The prevention of disability in later life is a major challenge facing industrialised societies. Primary care practitioners are well positioned to maintain and promote health in older people, but the British experience of population-wide preventive interventions has been disappointing. Health risk appraisal (HRA), an emergent information-technology-based approach from the USA, has the potential for fulfilling some of the objectives of the National Service Framework for Older People. Information technology and expert systems allow the perspectives of older people on their health and health risk behaviours to be collated, analysed and converted into tailored health promotion advice without adding to the workload of primary care practitioners. The present paper describes a preliminary study of the portability of HRA to British settings. Cultural adaptation and feasibility testing of a comprehensive health risk assessment questionnaire was carried out in a single group practice with 12,500 patients, in which 58% of the registered population aged 65 years and over participated in the study. Eight out of 10 respondents at all ages found the questionnaire easy or very easy to understand and complete, although more than one-third had or would have liked assistance. More than half felt that the length of the questionnaire was about right, and one respondent in 10 disliked some questions. Of those who completed the questionnaire and received tailored, written health promotion advice, 39% provided feedback on this with comments that can be used for increasing the acceptability of tailored advice. These findings have informed a wider exploratory study in general practice.

Maintenance of physical activity following an individualized motivationally tailored intervention

This study examined predictors of exercise maintenance following completion of a physical activity intervention. Sedentary adults recruited through newspaper advertisements were randomly assigned to receive either (a) a motivation-matched intervention with feedback reports that were individually tailored (IT) to psychological variables from social cognitive theory and the Transtheoretical Model via computer expert system, or (b) a standard, print-based intervention (ST). The intervention phase of the study included mailed assessments and intervention materials at baseline, 1, 3, and 6 months. An assessment-only follow-up was conducted 6 months after the end of the intervention (Month 12). Participants were assessed for current physical activity participation, motivational readiness for physical activity, a number of psychological constructs posited to influence participation in physical activity (e.g., self-efficacy), and current affect. Significantly more participants in the IT condition met or exceeded exercise participation goals at the end of the intervention period and maintained this level of physical activity through the Month 12 follow-up compared to ST participants. Prospective analyses revealed significant differences in several psychological constructs both at program entry (baseline) and the end of the intervention period between individuals who maintained their physical activity participation through Month 12 and those who did not. Results suggest that the maintenance of physical activity following the end of an active intervention program may be influenced by attitudes and behaviors acquired along with increased participation in physical activity, as well as by preexisting characteristics that individuals bring into treatment.

Nutrition and health promotion in older adults

During recent decades, the concept of health promotion has become a legitimate part of health care because of the aging of the postwar baby boom generation. As this population ages, the potential strain on health care systems will increase because the greatest use of health care services occurs during the last years of life. In older adults there are many correctable health factors that can be assessed through screening protocols. Hypertension, cholesterol, hearing, vision, diabetes, and cancer screening are well integrated into health promotion programs; nutrition promotion programs are not as well integrated. Reluctance to develop health promotion programs for older adults exists because of a perception that they would not follow such plans or change their lifestyles. However, longitudinal studies have shown that health promotion activities extend the number of years of health in older people although the relationship weakens in older age. Changes in diet and exercise patterns are most effective in the prevention of nutrition-related conditions when they are instituted early in life, but positive effects can occur at any age. If nutritional interventions are instituted early, a substantial reduction in health care expenditures may result from a decrease in the incidence or the delayed onset of these conditions. Changes in behaviors (reducing salt and fat intake) were positively associated with a belief that consuming a healthful diet would contribute to better health. The use of a variety of adult education theories and models will enhance behavior changes that lead to more healthful habits and enable a health educator to be successful in effecting change.

Studying coronary artery disease in the retirement community

A study was conducted to identify the prevalence of heart disease and associated health-related behaviors among continuing care retirement community (CCRC) residents; researchers also sought to identify management strategies for heart disease. Study results indicated that self-reported heart disease is prevalent among CCRC residents: 60% reported three or more health risk behaviors. The CCRC environment lends itself to providing various management advantages, including access to on-site clinicians, group education, and exercise and dining facilities to promote adherence to exercise, nutrition, and medical management plans.

Are older hazardous and harmful drinkers less likely to participate in health-related behaviors and practices as compared with nonhazardous drinkers?

OBJECTIVES

To describe the (1) prevalence of at-risk drinking and participation in health-related behaviors and practices and (2) associations of at-risk drinking with other health-related behaviors and practices among older persons completing a health-risk appraisal for the elderly (HRA-E).

DESIGN

Cross-sectional study using data from a self-administered, mailed survey sample.

SETTINGS

Persons from three organizations were surveyed: (1) the American Association of Retired Persons; and (2) a large medical group and (3) a community-based senior health center in southern California.

PARTICIPANTS

1,889 persons age 55 years and older.

MEASUREMENTS

The HRA-E included items on health characteristics, drinking behaviors (including amount of alcohol use and two alcoholism screening measures: the CAGE (Cut down, Annoyed, Guilty, Eye opener) and Short Michigan Alcoholism Screening Test-Geriatric version (SMAST-G), and participation in selected health-related behaviors and practices. Social drinkers were defined as those who drank fewer than 14 drinks weekly and screened negative on the CAGE (defined as two or more "no" responses) and SMAST-G. Hazardous drinkers drank fewer than 14 drinks weekly and screened negative. Harmful drinkers drank fewer than 14 drinks weekly and screened positive. Possible at-risk drinkers drank 14 or more drinks weekly and screened positive. Least squares regression models were used to assess the effects of hazardous, harmful, and possible at-risk drinking on each of the health-related practices and behaviors. We also conducted these analyses using three other definitions of social, possible at-risk, hazardous, and harmful drinking.

RESULTS

Of all respondents, 40% were social drinkers, 3% were harmful drinkers, 2% were hazardous drinkers, and 11% were possible at-risk drinkers. Hazardous, harmful, and possible at-risk drinkers commonly reported driving after drinking or being driven by someone who had been drinking (67%, 76%, and 64% respectively). Harmful and possible at-risk drinkers were more likely than social drinkers to smoke and were less likely to use seatbelts regularly. These findings were observed regardless of how the drinking groups were defined.

CONCLUSION

All groups of at-risk drinkers more commonly engaged in selected adverse health-related behaviors and practices than did social drinkers.

Using goal setting as a strategy for dietary behavior change

Recent reviews have noted that behavioral theory-based nutrition education programs are more successful at achieving food behavior change than knowledge-based programs and that a clear understanding of the mechanisms of behavior change procedures enable dietetics professionals to more effectively promote change. Successful dietary behavior change programs target 1 or more of the personal, behavioral, or environmental factors that influence the behavior of interest and apply theory-based strategies to influence or change those factors. Goal setting is a strategy that is frequently used to help people change. A 4-step goal-setting process has been identified: recognizing a need for change; establishing a goal; adopting a goal-directed activity and self-monitoring it; and self-rewarding goal attainment. The applications of goal setting in dietary interventions for adults and children are reviewed here. Because interventions using goal setting appear to promote dietary change, dietitians should consider incorporating the goal-setting strategies to enhance the behavior change process in nutrition education programs.

Identification of the factors associated with compliance to therapeutic diets in older adults with end stage renal disease

OBJECTIVE

To identify theory based factors pertinent to compliance with therapeutic diets.

DESIGN

A paper and pencil survey was read to volunteer hemodialysis patients in outpatient dialysis clinics.

SUBJECTS

A convenience sample of 276 hemodialysis patients aged 50 years and older who agreed to be interviewed during treatment.

STATISTICAL ANALYSIS

Descriptive statistics were used to report responses to all survey questions. The Fisher exact test was used to test associations between the dependent variable, dietary compliance, and independent variables, which included knowledge, perceived severity of illness, attitudes toward compliance, environmental factors, perceived barriers, self-efficacy, and perceived health benefits. Principal Components Analysis determined final scale items. Logistic regression was used to develop a model of independent variables profiling the compliant patient.

RESULTS

Subjects were more likely to be compliant if they indicated favorable attitudes toward compliance (P =.0076), a supportive environment (P =.0107), and knowledge about their diet (P =.0014). A logistic regression model of compliance indicated that subjects who followed their special diets were more likely to have higher knowledge (odds ratio [OR] = 1.092, 95% CI = 1.006, 1.186), perceived fewer barriers (OR = 1.094, 95% CI = 0.841, 1.226), being white race (OR = 0.710, 95% CI = 0.399, 1.263), and having gout (OR = 9.349, 95% CI = 1.139, 76.714).

APPLICATION

Health professionals should apply these findings in providing dietary education focused on improving not just knowledge, but attitudes and family support. Nutrition education and health promotion applications geared to non-white populations could be particularly important as tools to improve dietary compliance.

Health promotion for older Americans in the 21st century

OBJECTIVES

To provide a broad overview of the role of the individual, the physical environment, and the social environment on health and functioning in older adults (65 and older), and to highlight interventions and recommendations for action on each of these levels.

DATA SOURCES

Published studies and government reports on health and functioning in older Americans and on the individual, social, and physical environmental contributors to health were identified through journal and government documents review and computer library searches of medical and social science data bases for 1980-1999.

STUDY SELECTION

Preference was given to published studies and government reports that focused specifically on behavioral and environmental contributors and barriers to health promotion in Americans 65 and older and/or that highlighted creative interventions with relevance to this population. Both review articles and presentations of original research were included, with the latter selected based on soundness of design and execution and/or creativity of intervention described.

DATA EXTRACTION

Studies were examined and their findings organized under three major headings: (1) behavioral risk factors and risk reduction, including current government standards for prevention and screening; (2) the role of the physical environment; and (3) the role of the social environment in relation to health promotion of older adults.

DATA SYNTHESIS

Although most attention has been paid to the role of behavioral factors in health promotion for older adults, a substantial body of evidence suggests that physical and social environmental factors also play a key role. Similarly, interventions that promote individual behavioral risk reduction and interventions targeting the broader social or physical environment all may contribute to health in the later years.

CONCLUSIONS

With the rapid aging of America's population, increased attention must be focused on health promotion for those who are or will soon be older adults. Promising intervention strategies addressing the individual, the physical environment, and the social environment should be identified and tested, and their potential for replication explored, as we work toward a more comprehensive approach to improving the health of older Americans in the 21st century.

Determinants of physical activity initiation and maintenance among community-dwelling older persons

BACKGROUND

Understanding determinants of initiation and maintenance of an active lifestyle among older individuals is of great concern to public health because of the increasing evidence that lifestyle may alter the course of frequently occurring chronic diseases.

METHOD

Two thousand five hundred seven community-dwelling Medicare beneficiaries age 65 and over were interviewed at three points over 4 years regarding their physical activity, defined as a self-report of walking briskly, gardening, or heavy housework at least three times a week. Extensive data were also collected on health status, health services use, sociodemographics, and, at the final interview, self-mastery, importance of various factors in the decision to be physically active, and interaction with their physician regarding physical activity. Determinants of initiation and maintenance of physical activity were identified using logistic regressions.

RESULTS

Forty-one percent maintained an active lifestyle; 12% initiated an active lifestyle; 22% declined to become sedentary; 25% were sedentary at all observation. Predictors of both initiation and maintenance of physical activity were younger age, moderate to excellent health, and the patient's belief that physical activity was important to his/her health. Among the 301 patients who initiated activity, 40% said their physician was a very important influence.

CONCLUSIONS

Strengthening the belief of older individuals in the benefits to their health of physical activity holds promise for increasing the proportion of community-dwelling older persons who move from a sedentary lifestyle to a more physically active lifestyle and for maintaining such activity.

Mortality, health services use, and health behavior in a cohort of well older adults

OBJECTIVES

To construct an evidence-based Good Health Behavior Score and examine the relationship between aggregate health behaviors, mortality, and health services utilization in the last year of life in a cohort of well older adults.

DESIGN

A prospective cohort.

SETTING

A large health maintenance organization.

PARTICIPANTS

1867 older enrollees who responded to a health promotion survey.

MEASUREMENTS

A baseline self-administered questionnaire was used to ascertain health behaviors in 1987-1988, and vital status was determined 48 months later. A Good Health Behavior Score was calculated, and a Cox proportional hazards model was used to compare high, middle, and low score groups regarding risk of death. For those who died, differences in amount and type of health services utilization in relation to the summary score were compared for the year before death.

RESULTS

During the 4 years of follow-up, the mortality rate for the mid-level score group was 50% less, and in the highest score group was 70% less, than in the lowest score group. Among decedents, no significant differences were found between high and low Good Health Behavior score groups for inpatient and outpatient utilization, pharmacy use, or total cost during the last year of life.

CONCLUSION

An easily developed and simple health behavior score can predict short term mortality quite strongly. Medical care costs in the last year of life were similar in individuals with higher and lower health behavior scores.

Physical activity interventions using mass media, print media, and information technology

INTRODUCTION

Media-based physical activity interventions include a variety of print, graphic, audiovisual, and broadcast media programs intended to influence behavior change. New information technology allows print to be delivered in personalized, interactive formats that may enhance efficacy. Media-based interventions have been shaped by conceptual models from health education, Social Cognitive Theory, the Transtheoretical Model, and Social Marketing frameworks.

METHODS

We reviewed 28 studies of media-based interventions of which seven were mass media campaigns at the state or national level and the remaining 21 were delivered through health care, the workplace, or in the community.

RESULTS

Recall of mass-media messages generally was high, but mass-media campaigns had very little impact on physical activity behavior. Interventions using print and/or telephone were effective in changing behavior in the short term. Studies in which there were more contacts and interventions tailored to the target audience were most effective.

CONCLUSION

A key issue for research on media-based physical activity interventions is reaching socially disadvantaged groups for whom access, particularly to new forms of communication technology, may be limited. There is a clear need for controlled trials comparing different forms and intensities of media-based physical activity interventions. Controlled studies of personalized print, interactive computer-mediated programs, and web-based formats for program delivery also are needed. The integration of media-based methods into public and private sector service delivery has much potential for innovation.

Mediating variable framework in physical activity interventions. How are we doing? How might we do better?

INTRODUCTION

Behavioral science provides the foundation for physical activity interventions. The mediating variable framework is used to assess the status of physical activity interventions and the roles that are, or could be played, by behavioral theory.

METHODS

Twenty-five physical activity intervention studies and 45 physical activity correlational studies were found in the literature, tabulated, and included in the analysis.

RESULTS

Behavioral interventions for promoting physical activity have worked primarily when participants were motivated enough to volunteer or when a school-based physical education program changed. In most cases, behavioral or psychosocial theory accounted for 30% or less of the variability in physical activity behaviors. Most intervention studies do not measure mediating variables, and when they do, they do not systematically effect changes in all the mediating variables on which they are predicated.

DISCUSSION

To increase the effectiveness of physical activity interventions, more physical activity research should focus on a better understanding of the predictors of physical activity and toward interventions demonstrated to effect change in these predictors of physical activity.

CONCLUSION

Changing the focus to basic behavioral and social science and mediator change research should provide a more systematic and cost-effective approach to increasing the effectiveness of physical activity interventions.

Development of a health education programme for elderly with age-related macular degeneration: a focus group study

Age-related macular degeneration is a serious public health problem, and in most cases no cure exists. One available intervention is low vision rehabilitation, and there is a lack of programmes for the elderly. The purpose of this paper is to present the results of an evaluation of a group-based health education programme. This programme comprised six to eight 2-3 hour meetings, once a week, for persons with age-related macular degeneration. Each group consisted of four to six participants. The goal of the programme, which has its roots in the health belief model, was to sustain and restore the participants' performance of their daily activities. The tool used for process evaluation was focus group methodology, and eight focus groups were involved. Forty five persons, whose average age was 80 years, took part in the evaluation. The results indicated that the participants were, on the whole, pleased with the content of the programme. There were, however, some indications that they did not understand all the information provided. Social support, regained hope and meeting others with the same disease were reported as positive aspects of the health education programme. The importance of the group leader's role in guiding this health education programme was emphasised. Furthermore, with regard to the composition of the groups, the participants pointed out that it was important to consider variation in visual acuity, so as to provide different models for comparison, and whether both sexes should participate in all groups. Finally, several suggestions for improving the programme are put forward.

Development of a health risk appraisal for the elderly (HRA-E)

The purpose of this project is to develop a health risk appraisal for the elderly (HRA-E) and test its application in both medical and nonmedical settings. The HRA-E system consists of a questionnaire and software for computer-generation of personalized reports to participants, 55 years and older, and their physicians. Items in the questionnaire cover a comprehensive range of content domains relevant to health promotion in the elderly. The goal of the HRA-E system is to prevent functional decline. Samples of eligible subjects from the American Association of Retired Persons (AARP), a group practice, and a senior center were extended invitations to participate. Those responding affirmatively to the invitation were given a questionnaire and evaluation form. Each person who returned the questionnaire received his or her personal report and a second evaluation form. Four months after receiving their reports, respondents were questioned about behavior changes during the interim. Preliminary findings, based on 1895 respondents, indicate that nearly all participants found the questionnaire easy to complete and were pleased with its overall length. In addition, most participants read their reports, and many planned to take action, based on report recommendations. In the next phase of this project, the intent is to refine the questionnaire, extend the intervention protocols for longitudinal application, and evaluate its impact on health-related behaviors, medical care utilization, and functional decline.

Getting started--a review of physical activity adoption studies

The aim of this paper has been to review methods that have been found to be effective in getting sedentary adults to adopt physical activity, to examine these methods within the multilevel framework conceptualised by Winett et al, and to provide recommendations for future research to test new methods and their effectiveness in leading to the adoption of physical activity in sedentary populations. Searches for relevant studies were conducted on the Medline computerised database. Additional studies were located in reference sections of these studies and other review papers. Surveys that specifically identified determinants of adoption of physical activity in adults were included. Reviewed articles were selected on the basis of quasi-experimental and experimental designs that specifically examined the question of how to get sedentary adults to adopt a programme of physical activity or exercise, had completely described methods, and evaluated the effectiveness of methods of increasing physical activity and/or exercise. While numerous reviews have been written on determinants on physical activity adoption and maintenance, only two prospective surveys have identified specifics of adoption of physical activity. Most of the evidence for techniques that help inactive people to adopt physical activity comes from quasi-experimental and experimental intervention studies examining various cognitive and behavioural strategies at the individual level. Fewer studies have examined techniques at the interpersonal, organisational, community, environmental, and policy level. More prospective observational studies aimed at homogeneous subgroups are needed to identify correlates of physical activity adoption to help tailor interventions. Continued clinical studies are needed to differentiate the necessary and sufficient strategies at the personal and interpersonal levels. Interventions aimed at environmental, institutional, and social levels remain largely unexplored and there is a need for more research that specifically targets inactive subgroups at these levels.
