Towards healthy food retail: An assessment of public health nutrition workforce capacity to work with stores

OBJECTIVE

This article aims to investigate the capacity of nutrition professionals to engage in food retail practice change to improve population diet.

METHODS

Convergent mixed method design was used that includes pre-interview surveys, in-depth interviews, and retrospective mapping of service provision. The study was conducted in organisations that provide a nutrition professional service to food retail stores in remote Australia. The study participants include 11 nutrition professionals and eight organisation representatives, including managers, organisation directors and policy officers. Systems-mapping and thematic analysis of the in-depth interviews were conducted using a capacity development framework. Descriptive analysis was applied to pre-interview survey and mapping data.

RESULTS

A gap between the aspirational work and current capacity of nutrition professionals to engage effectively with stores was identified. Engagement with stores to improve population health was valued by organisations. Dominance of the medical health model limited organisation strategic support for store work and created barriers. Key barriers included the limited access to training, decision-support tools, information, financial resources and organisational structures that directed store work.

CONCLUSIONS

Provision of adequate store-specific training, resources and organisational support may empower the nutrition professional workforce to be powerful leaders in co-design for healthy food retail.

IMPLICATIONS FOR PUBLIC HEALTH

Building capacity for this critical workforce to engage in food retail practice change must consider the influence of the broader health system and employer organisations and need for access to evidence-based decision-support tools.

Pathways to Sustainability: 8-Year Follow-Up From the PROSPER Project

The large-scale dissemination of evidence-based practices (EBPs) is often hindered by problems with sustaining initiatives past a period of initial grant funding. Communities often have difficulty generating resources needed to sustain and grow their initiatives, resulting in limited public health impact. The PROSPER project, initiated in 2001, provided community coalitions with intensive technical assistance around marketing, communications, and revenue generating strategies. Past reports from PROSPER have indicated that these coalitions were successful with sustaining their programming, and that sustainability could be predicted by early aspects of team functioning and leadership. The current study examines financial sustainability 8 years following the discontinuation of grant funding, with an emphasis on sources of revenue and the relationships between revenue generation, team functioning, and EBP participation. This study used four waves of data related to resource generation collected between 2004 and 2010 by PROSPER teams in Iowa and Pennsylvania. Teams reported annually on the amount and sources of funding procured, as well as annual reports of team functioning and leadership and annual reports of EBP participation by youth and parents. Data revealed that teams' overall revenue generation increased over time. There was significant variation in success with revenue generation at both the community level and across the two states. Teams accessed a variety of sources. Cash revenue generation was positively and predictively associated with EBP participation, but relationships with team functioning and leadership ratings varied significantly by state. State level differences in in-kind support were also apparent. The results indicated that there are different pathways to sustainability, and that no one method works for all teams. The presence of state level infrastructures available to support prevention appeared to account for significant differences in sustainability success between Pennsylvania and Iowa.

Evaluating health promotion in schools: a case study of design, implementation and results from the Hong Kong Healthy Schools Award Scheme

Health promoting schools (HPS) and Healthy Schools Award Schemes from a number of countries have demonstrated positive changes in children's health behaviours and the culture and organisation of the school. The Hong Kong Healthy Schools Award Scheme (HKHSA) aims to promote staff development, parental education, involvement of the whole school community, and linkage with different stakeholders to improve the health and well-being of the pupils, parents and staff, and the broader community, supported by a system to monitor the achievement. This concept is very much in line with the research literature on school effectiveness and improvement. The indicators examined to evaluate the success of the HKHSA reflect outcomes related to both health and education and are not limited to changes in population health status. The early results demonstrated significant improvements in various aspects of student health and also improvement in school culture and organisation. The evaluation framework described in this paper and data collected to assess how schools perform in the HKHSA scheme, provides insight into how HPSs could lead to better outcomes for both education and health.

Increasing the Health Promotive Capacity of Human Environments

This article offers an integration of two different perspectives on health promotion research and practice: one emphasizing the concept of community capacity for health improvement and the other focusing on the notion of health supportive environments. These two approaches generally have emphasized different kinds of community assets for health promotion. Specifically, community capacity research has focused on the cultivation of human resources (e.g., collaborative coalitions, participatory decision-making, health education strategies) for health promotion, whereas environmentally oriented research has underscored the influence of material resources (e.g., the built environment, natural resources, technological infrastructure) on important health behaviors and outcomes. Combining these two streams of health promotion research yields a broader understanding of the health promotive capacity of human environments and suggests several “best process” guidelines for enhancing health promotion practice.

Realistic Expectations: Investing in Organizational Capacity Building for Chronic Disease Prevention

Purpose.

This article presents findings that explore investment in organizational capacity building for chronic disease prevention. Specifically, this analysis examines variation in investment inputs, intervention outputs, and capacity changes to inform expectations of health-promotion capacity-building investment.

Design/Setting.

This multiple case study involving both qualitative and quantitative data is based on seven provincial dissemination projects involved in the Canadian Heart Health Initiative.

Methods.

Data on investment, number, and type of capacity-building activities and capacity changes come from a questionnaire, key informant interviews, and project report analysis. Quantitative data were analyzed descriptively and for trends, while qualitative data were analyzed thematically.

Results.

Per capita investments in capacity building ranged from a low of $0.21 in Ontario to $167.41 in Prince Edward Island. Multiple, tailored capacity-building interventions were used in each project. Mostly positive but modest changes were observed in at least five dimensions of capacity in all but one project.

Conclusion.

These findings reveal that capacity building for chronic disease prevention requires a long-term investment and is context specific. Even limited investment can produce interventions that appear to positively influence capacity for chronic disease prevention. The findings also suggest an urgent need to expand surveillance to include indicators of capacity-building investments and interventions to allow policy makers to make more informed decisions about investments in public health.

A Conceptual Model of Community Capacity Development for Health Promotion in the Alberta Heart Health Project

Purpose. The objective of this study was to derive a conceptual model of community capacity development for health promotion based on the 5-year demonstration phase of the Alberta Heart Health Project. Method. Community actions associated with successful implementation and uptake of initiatives in four diverse target sites were identified by case study evaluation. Results. Thirteen common elements of capacity development were found across the projects and categorized to define three primary dimensions of the process: (a) leadership that provided a driving force for implementation, (b) policy making that ensured diffusion and sustainability, and (c) use of local community resources and infrastructure. A conceptual model was constructed using these 3 dimensions and their interactions. Conclusion. Effective implementation of community health initiatives to promote heart health can be conceptualized as the involvement of local leadership, policy advocacy, and enhancement of existing infrastructure. The model highlights building these dimensions of community capacity development for health promotion.

Assessing Organizational Capacity to Deliver HIV Prevention Services Collaboratively: Tales from the Field

Collaborative efforts between university researchers and community entities such as citizen coalitions and community-based organizations to provide health prevention programs are widespread. The authors describe their attempt to develop and implement a method for assessing whether community organizations had the organizational capacity to collaborate in a national study to prevent HIV infection among young men who have sex with men and what, if any, needs these institutions had for organizational capacity development assistance. The Feasibility, Evaluation Ability, and Sustainability Assessment (FEASA) combines qualitative methods for collecting data (interviews, organizational records, observations) from multiple sources to document an organization's capacity to provide HIV prevention services and its capacity-development needs. The authors describe experiences piloting FEASA in 13 communities and the benefits of using a systematic approach to partnership development.

Association between organizational capacity and involvement in chronic disease prevention programming among Canadian public health organizations

In the context of the emerging field of public health services and systems research, this study (i) tested a model of the relationships between public health organizational capacity (OC) for chronic disease prevention, its determinants (organizational supports for evaluation, partnership effectiveness) and one possible outcome of OC (involvement in core chronic disease prevention practices) and (ii) examined differences in the nature of these relationships among organizations operating in more and less facilitating external environments. OC was conceptualized as skills and resources/supports for chronic disease prevention programming. Data were from a census of 210 Canadian public health organizations with mandates for chronic disease prevention. The hypothesized relationships were tested using structural equation modeling. Overall, the results supported the model. Organizational supports for evaluation accounted for 33% of the variance in skills. Skills and resources/supports were directly and strongly related to involvement. Organizations operating within facilitating external contexts for chronic disease prevention had more effective partnerships, more resources/supports, stronger skills and greater involvement in core chronic disease prevention practices. Results also suggested that organizations functioning in less facilitating environments may not benefit as expected from partnerships. Empirical testing of this conceptual model helps develop a better understanding of public health OC.

Building capacity for dementia care in Latin America and the Caribbean

Latin America and the Caribbean (LAC) have limited facilities and professionals trained to diagnose, treat, and support people with dementia and other forms of cognitive impairment. The situation for people with dementia is poor, and worsening as the proportion of elderly in the general population is rapidly expanding. We reviewed existing initiatives and provided examples of actions taken to build capacity and improve the effectiveness of individuals, organizations, and national systems that provide treatment and support for people with dementia and their caregivers. Regional barriers to capacity building and the importance of public engagement are highlighted. Existing programs need to disseminate their objectives, accomplishments, limitations, and overall lessons learned in order to gain greater recognition of the need for capacity-building programs.

A four-part ecological model of community-focused therapeutic recreation and life skills services for children and youth with disabilities

AIM

This article presents a four-part model of community-focused therapeutic recreation and life skills services for children's rehabilitation centres.

METHOD AND RESULTS

The model is based on 15 years of clinical and management practice in a Canadian context combined with evidence from the literature on community-focused service delivery. The model incorporates an ecological approach and principles from models of therapeutic recreation, community capacity building, and health promotion, as well as client/family-centred care. The four pillars of the model reflect a set of integrated services and principles designed to support the participation of children and youth with disabilities in community activities. The pillars involve providing community outreach services, providing community development services, sharing physical and educational resources with community partners, and promoting the organization as a community facility that provides adapted physical space and specialized instruction. The lessons learned in implementing the model are discussed, including the importance of ensuring the sustainability of community recreation programmes.

CONCLUSIONS

The model will be of use to managers and service organizations seeking to develop an integrated programme of community-focused therapeutic recreation and life skills services based on a collaborative capacity-building approach.

Exploring facilitators and barriers to individual and organizational level capacity building: outcomes of participation in a community priority setting workshop

This article explores facilitators and barriers to individual and organizational capacity to address priority strategies for community-level chronic disease prevention. Interviews were conducted with a group of participants who previously participated in a community priority-setting workshop held in two Alberta communities. The goal of the workshop was to bring together key community stakeholders to collaboratively identify action strategies for preventing chronic diseases in their communities. While capacity building was not the specific aim of the workshop, it could be considered an unintended byproduct of bringing together community representatives around a specific issue. One purpose of this study was to examine the participants' capacity to take action on the priority strategies identified at the workshop. Eleven one-on-one semi-structured interviews were conducted with workshop participants to examine facilitators and barriers to individual and organizational level capacity building. Findings suggest that there were several barriers identified by participants that limited their capacity to take action on the workshop strategies, specifically: (i) organizations' lack of priorities or competing priorities; (ii) priorities secondary to the organizational mandate; (iii) disconnect between organizational and community priorities; (iv) disconnect between community organization priorities; (v) disconnect between organizations and government/funder priorities; (vi) limited resources (i.e. time, money and personnel); and, (vii) bigger community issues. The primary facilitator of individual capacity to take action or priority strategies was supportive organizations. Recognition of these elements will allow practitioners, organizations, governments/funders, and communities to focus on seeking ways to improve capacity for chronic disease prevention.

Conceptualizing dissemination research and activity: the case of the Canadian Heart Health Initiative

Cardiovascular diseases are now the world's leading cause of death. To reduce high rates of such preventable premature deaths, evidence-based approaches to heart health promotion must be disseminated across public health systems. To succeed, we must build capacity to disseminate strategies that are practical and effective. However, we know little about such dissemination, and we lack both conceptual frameworks to guide our thinking and appropriate scientific methodologies. This article presents conceptual and analytic frameworks that integrate several approaches to understanding and studying dissemination processes within public health systems. This work is based on the Canadian Heart Health Dissemination Project, a research program examining a national heart health dissemination initiative. The primary focus is the development of a systematic protocol for measuring levels of capacity and dissemination, and determining successful conditions for, and barriers to, capacity and dissemination, as well as the nature of the relationship between these key concepts.

Sustaining a school-based prevention program: results from the Aban Aya Sustainability Project

Sustaining effective school-based prevention programs is critical to improving youth and population-based health. This article reports on results from the Aban Aya Sustainability Project, an effort to sustain a school-based prevention program that was tested via a randomized trial and targeted violence, drug use, and risky sex-related behaviors among a cohort of 5th-grade African American children followed through 10th grade. Sustainability project health educators trained parent educators to deliver the Aban Aya prevention curriculum in five schools, and project researchers studied the resultant curricular implementation and relations between the research and school-based teams. Study results showed uneven implementation across the five schools that we largely attributed to parent educator preparation and parent educator-health educator relations. These and related results are discussed to answer the study's primary research question: How viable was the sustainability project's parent-centered approach to sustaining a school-based prevention program?

The unbearable lightness of technocratic efforts at dengue control

OBJECTIVE

To identify key elements that should provide an added value and assure sustainable effects of the deployment of technical tools for Aedes aegypti control.

METHODS

An observational study was conducted between April 2001 and March 2002 in 30 blocks (1574 houses) in the central zone of Guantanamo city. A trial that combined two complementary technical interventions, the distribution of new ground level water tanks and the intensive use of insecticide, was nested in May 2001. Another 30 blocks (1535 houses) were selected as control area. We assessed community perceptions and household risk behaviour at baseline and after 9 months, and measured the trial's impact through entomological indices.

RESULTS

Perceived self efficacy to solve A. aegypti infestation and prevent dengue was not modified. We found no changes in behaviour. In the study area the container indices decreased significantly from 0.7% before to 0.1% 1 month after the intervention. Six months later, they had increased to 2.7% and uncovered new water tanks constituted 75.9% of all breeding sites. Over the 9 months after the trial the average monthly house indices were similar in the study and control areas. A technical approach and lack of community involvement in the trial's implementation were the main causes of these short-lived results.

CONCLUSIONS

Top-down deployment of technical tools without active involvement of the community has a temporary effect and does not lead to the behavioural changes necessary for sustainable A. aegypti control.

Sustaining health promotion programs within sport and recreation organisations

The involvement of the sport and recreation sector as a setting for health promotion is a new strategy implemented by health policy makers and strategic planners. Strategies to promote and sustain health promotion activities are important considering the risk that programs may cease after initial funding ends. This study explored the factors affecting the sustainability of a sport- and recreation-based health promotion program. A stratified sampling method was used to select four of the nine Regional Sports Assemblies (RSAs) that delivered a state-wide health promotion program funded by the Victorian Health Promotion Foundation in Australia. Data were collected from in-depth interviews with four Executive Officers (EOs) and focus group discussions with their Boards of Management. A sustainability checklist with pre-specified dimensions (e.g. organisational setting, broader community environment, and program design and implementation) guided data collection and analysis. The results showed that the organisational setting and the broader community environment supported program institutionalisation; whilst the design and implementation of the program worked against institutionalisation. The capacity of the organisations to generate new funds for the program was limited; the relationship between the central funding organisation and the Boards of Management was weak; and the program did not support the retention of staff. The engagement of sport and recreation organisations has potential to facilitate health promotion and public health. To enhance organisational capacity and achieve program sustainability, it is important that organisational processes, structures, and resources that support long-term health promotion practice are effectively and efficiently planned and managed.

Using participatory design to develop (public) health decision support systems through GIS

Background

Organizations that collect substantial data for decision-making purposes are often characterized as being 'data rich' but 'information poor'. Maps and mapping tools can be very useful for research transfer in converting locally collected data into information. Challenges involved in incorporating GIS applications into the decision-making process within the non-profit (public) health sector include a lack of financial resources for software acquisition and training for non-specialists to use such tools. This on-going project has two primary phases. This paper critically reflects on Phase 1: the participatory design (PD) process of developing a collaborative web-based GIS tool.

Methods

A case study design is being used whereby the case is defined as the data analyst and manager dyad (a two person team) in selected Ontario Early Year Centres (OEYCs). Multiple cases are used to support the reliability of findings. With nine producer/user pair participants, the goal in Phase 1 was to identify barriers to map production, and through the participatory design process, develop a web-based GIS tool suited for data analysts and their managers. This study has been guided by the Ottawa Model of Research Use (OMRU) conceptual framework.

Results

Due to wide variations in OEYC structures, only some data analysts used mapping software and there was no consistency or standardization in the software being used. Consequently, very little sharing of maps and data occurred among data analysts. Using PD, this project developed a web-based mapping tool (EYEMAP) that was easy to use, protected proprietary data, and permit limited and controlled sharing between participants. By providing data analysts with training on its use, the project also ensured that data analysts would not break cartographic conventions (e.g. using a chloropleth map for count data). Interoperability was built into the web-based solution; that is, EYEMAP can read many different standard mapping file formats (e.g. ESRI, MapInfo, CSV).

Discussion

Based on the evaluation of Phase 1, the PD process has served both as a facilitator and a barrier. In terms of successes, the PD process identified two key components that are important to users: increased data/map sharing functionality and interoperability. Some of the challenges affected developers and users; both individually and as a collective. From a development perspective, this project experienced difficulties in obtaining personnel skilled in web application development and GIS. For users, some data sharing barriers are beyond what a technological tool can address (e.g. third party data). Lastly, the PD process occurs in real time; both a strength and a limitation. Programmatic changes at the provincial level and staff turnover at the organizational level made it difficult to maintain buy-in as participants changed over time. The impacts of these successes and challenges will be evaluated more concretely at the end of Phase 2.

Conclusion

PD approaches, by their very nature, encourage buy-in to the development process, better addresses user-needs, and creates a sense of user-investment and ownership.

Building the backbone for organisational research in public health systems: development of measures of organisational capacity for chronic disease prevention

BACKGROUND

: Research to investigate levels of organisational capacity in public health systems to reduce the burden of chronic disease is challenged by the need for an integrative conceptual model and valid quantitative organisational level measures.

OBJECTIVE

To develop measures of organisational capacity for chronic disease prevention/healthy lifestyle promotion (CDP/HLP), its determinants, and its outcomes, based on a new integrative conceptual model.

METHODS

Items measuring each component of the model were developed or adapted from existing instruments, tested for content validity, and pilot tested. Cross sectional data were collected in a national telephone survey of all 216 national, provincial, and regional organisations that implement CDP/HLP programmes in Canada. Psychometric properties of the measures were tested using principal components analysis (PCA) and by examining inter-rater reliability.

RESULTS

PCA based scales showed generally excellent internal consistency (Cronbach's alpha = 0.70 to 0.88). Reliability coefficients for selected measures were variable (weighted kappa(kappa(w)) = 0.11 to 0.77). Indicators of organisational determinants were generally positively correlated with organisational capacity (r(s) = 0.14-0.45, p<0.05).

CONCLUSIONS

This study developed psychometrically sound measures of organisational capacity for CDP/HLP, its determinants, and its outcomes based on an integrative conceptual model. Such measures are needed to support evidence based decision making and investment in preventive health care systems.

Challenges and facilitating factors in sustaining community-based participatory research partnerships: lessons learned from the Detroit, New York City and Seattle Urban Research Centers

In order to address the social, physical and economic determinants of urban health, researchers, public health practitioners, and community members have turned to more comprehensive and participatory approaches to research and interventions. One such approach, community-based participatory research (CBPR) in public health, has received considerable attention over the past decade, and numerous publications have described theoretical underpinnings, values, principles and practice. Issues related to the long-term sustainability of partnerships and activities have received limited attention. The purpose of this article is to examine the experiences and lessons learned from three Urban Research Centers (URCs) in Detroit, New York City, and Seattle, which were initially established in 1995 with core support from the Centers for Disease Control and Prevention (CDC). The experience of these Centers after core funding ceased in 2003 provides a case study to identify the challenges and facilitating factors for sustaining partnerships. We examine three broad dimensions of CBPR partnerships that we consider important for sustainability: (1) sustaining relationships and commitments among the partners involved; (2) sustaining the knowledge, capacity and values generated from the partnership; and (3) sustaining funding, staff, programs, policy changes and the partnership itself. We discuss the challenges faced by the URCs in sustaining these dimensions and the strategies used to overcome these challenges. Based on these experiences, we offer recommendations for: strategies that partnerships may find useful in sustaining their CBPR efforts; ways in which a Center mechanism can be useful for promoting sustainability; and considerations for funders of CBPR to increase sustainability.

Allies against asthma: a midstream comment on sustainability

The ability of a coalition to sustain its impact in a community over time is a vital element of success. Four sustainability strategies have emerged among Allies Against Asthma coalitions: (a) resource development; (b) institutionalization; (c) system change, including policy change; and (d) capacity building. Although it is too early to determine their ultimate success, a number of important lessons have been learned about the coalitions' sustainability efforts: (a) sustainability must be considered as a planning principle, (b) data demonstrating success will enhance efforts to sustain worthy efforts, (c) ongoing communication and relationship building are critical elements of sustainability, (d) considering sustainability can help guide membership recruitment efforts, (e) coalitions with previous asthma and/or coalition experience may be better prepared to address sustainability within a short project period, and (f) although difficult to fund, the coalition infrastructure itself is key to successfully sustaining outcomes and activities.

Understanding Facilitators of and Barriers to Health Promotion Practice

The health promotion best practices literature is imbued with hope for knowledge mobilization, enhanced practice, and improved population health. Given constrained medical care systems, health promotion is key to reducing the significant burden of chronic disease. However, we have seen little evidence of change. This article investigates facilitators of, and barriers to, three stages of health promotion practice in public health organizations, interagency coalitions, and volunteer committees. The article focuses not on what works but why it does or does not, drawing on five case studies within the Canadian Heart Health Initiative. Results indicate that the presence or absence of appropriately committed and/or skilled people, funds and/or resources, and priority and/or interest are the most common factors affecting all stages of health promotion practice. The article extends the literature on internal and external factors affecting health promotion and highlights strategic influences to consider in support of effective health promotion practice.

Fostering organizational change through a community-based initiative

Program funders and managers are increasingly interested in fostering changes in the policies, practices, and procedures of organizations participating in community-based initiatives. But little is known about what factors contribute to the institutionalization of change. In this study, the authors assess whether the organizational members of the Bronx Health REACH Coalition have begun to change their functioning and role with regard to their clients and their staff and in the broader community, apart from their implementation of the funded programs for which they are responsible. The study identifies factors that seemed to contribute to or hinder such institutional change and suggests several strategies for coalitions and funders that are seeking to promote and sustain organizational change.

Using linking systems to build capacity and enhance dissemination in heart health promotion: a Canadian multiple-case study

The purpose of this paper is to examine the utility of linking systems between public health resource and user organizations for health promotion dissemination and capacity building, and to identify factors related to the success of linking systems. The design is a parallel-case study using key informant interviews and content analysis of project reports (synthesized qualitative and quantitative data) of three provincial dissemination projects of the Canadian Heart Health Initiative-Dissemination Phase. Each provincial project used linking activities with public health user groups including meetings, skill building, resources, collaboration, networking and research feedback to facilitate capacity building for and implementation of heart health promotion activities. This paper presents empirical examples of linking system designs, activities, and qualitative and quantitative changes in the public health user groups' health promotion capacity, program delivery and sustainability. The findings indicate enhanced health promotion skills, partnerships, resources, infrastructure, and increased programming and sustainability in the targeted public health organizations of all three provincial projects. Identified barriers to the success of linking systems included lack of appropriately skilled personnel, funds, buy-in and leadership. We conclude that linking systems can be flexibly used to build capacity and disseminate health promotion innovations, and suggest conditions for success.

Strengthening the HIV/AIDS service delivery system in Liberia: an international research capacity-building strategy

Liberia's prolonged post-conflict transition has negatively impacted its health infrastructure, including the functioning of its health care delivery system. Considering the current national health crises, a study was conducted to identify research gaps and the need to propose changes for improving the health care delivery system in the country. The study results clearly demonstrated a lack of HIV/AIDS research infrastructure including organizational structure, linkages, leadership, champions, expertise, resources, and policies and procedures. Alignment of research needs and practice, and research use to support HIV/AIDS service delivery programmes in the country was also limited. An international research capacity-building partnership is proposed as an effective planned change strategy to strengthen HIV/AIDS-related research infrastructure and to inform management and practice within the Liberian HIV/AIDS service delivery system. A proposed capacity-building planning model can also strengthen research infrastructure and the production and use of research to positively impact the HIV/AIDS epidemic in Liberia and other developing countries.

Health Care Needs of Elderly in a Rural Community in Korea

The purpose of this study was to examine the need for health and social support services of the elderly who lived alone in a rural community in Korea. All 97 elderly who lived alone in 32 communities in H Eub(county), Kangwon Province participated in the study. Comprehensive assessment was conducted on their need for these services and on the status of their physical, functional, cognitive, emotional, nutritional, social, and environmental factors. Data were collected by eight public health nurses and were analyzed using descriptive statistics and stepwise multiple regression. Elderly subjects living alone had more than one disease, limited gait ability, limited functional capabilities as measured by the combination of activities of daily living and instrumental activities of daily living, and poor nutritional state. They had low level of cognitive ability, high level of depression, and high level of need for financial support. They engaged in no or little exercise. Service need for physical care was highest, and the factors contributing to the service need were gait ability, functional capabilities, nutrition state, and perceived health status. The results of this study indicate that their needs are multiple and complex. Well-coordinated health services that integrate social welfare services for elderly population who live alone are recommended.

Methodologic advances and ongoing challenges in designing community-based health promotion programs

Community intervention trials continue to attract researchers as potential ways to achieve widespread, long-term change in health behaviors. The first generations of community studies were somewhat unsophisticated in design and analysis, and their promise may have been overstated. As design and analysis issues were better defined, as secular trends caught up with the behaviors that researchers were trying to change, or as other unknown variables affected community studies, small effects of interventions were observed in community trials. Discussions were held in professional meetings and reported in the literature: Should community trials be discontinued? In general, the answer was a qualified no. In this paper, we briefly review some of the many advances made in community intervention trials, and address in more detail the challenges ahead.

Reconsidering community-based health promotion: promise, performance, and potential

Contemporary public health emphasizes a community-based approach to health promotion and disease prevention. The evidence from the past 20 years indicates, however, that many community-based programs have had only modest impact, with the notable exception of a number of HIV prevention programs. To better understand the reasons for these outcomes, we conducted a systematic literature review of 32 community-based prevention programs. Reasons for poor performance include methodological challenges to study design and evaluation, concurrent secular trends, smaller-than-expected effect sizes, limitations of the interventions, and limitations of theories used. The effectiveness of HIV programs appears to be related in part to extensive formative research and an emphasis on changing social norms.

A Model for Building Collective Capacity in Community-Based Programs: The Elderly in Need Project

As the focus of health promotion moves from individuals to organizations, communities and broader social policy, the models that guide public health program planning and development need reexamination. Public health nurses are gaining experience in strengthening and supporting the ability of communities to grow and change. This study aimed to illuminate the process. Data, gathered as part of an action research project to develop individual and community-based strategies to decrease isolation in frail older adults, provided a rich source of qualitative data. Analysis was directed toward identifying the factors and processes of capacity-building. The emerging model was clarified and partially validated with academics and practitioners from health promotion programs across the age span. Four stages of building collective capacity were identified: identifying common ground, working cooperatively, working in partnership, and working across the community. At each stage, processes of relationship building, project management and capacity-building resulted in stage specific products. A model of building collective capacity, grounded in community health practice and supported by the literature provides a base for developing practice indicators, and practice guidelines which will strengthen the ability to reach health goals.

Durability, dissemination, and institutionalization of worksite tobacco control programs: Results from the working well trial

Durability, dissemination and institutionalization o f tobacco control activities are reported, based on the Working Well worksite cancer control intervention study (n = 83 worksites). Tobacco control activities increased significantly in intervention worksites as a result of research-supported activities but were not sustained 2 years after the conclusion of the intervention. Intervention sites were more likely than control sites to initiate and maintain structures for institutionalizing programs, such as assigning a committee responsibility for health-promotion programs or providing a budget for health-promoting activities. Dissemination of the program to control worksites had little impact on the level of smoking control activities in control worksites. Although program durability was not a primary aim of this intervention study, these analyses provide an important assessment of program maintenance beyond a funded intervention and underscore the need for additional research to identify effective organizational strategies for institutionalization of worksite health-promotion programs.

Durability and diffusion of the nutrition intervention in the Working Well Trial

BACKGROUND

The Working Well Trial (WWT) emphasized employee participation in the planning and implementation of the health promotion intervention. These participatory strategies were intended to promote institutionalization of the health promotion program and thereby encourage maintenance of the intervention activities. We used data from 107 worksites in the WWT to test whether the nutrition intervention activities were maintained after the research program (i.e., durability) or were adopted by control sites (i.e., diffusion).

METHODS

At baseline, upon the completion of the 2-year intervention, and 2 years later, we conducted organization surveys regarding worksite health promotion activities. A nutrition activity score from 0 to 3 was calculated based on availability of nutrition-related programs, self-help manuals or guides, and videos, tapes, brochures, or posters.

RESULTS

From baseline to the end of the intervention, there was a significant increase in the nutrition activity score in intervention worksites compared with the controls (P < 0.001). However, 2 years later, there was no difference between intervention and control worksites. In addition, there was no significant increase in the nutrition activity score in control site 2 years after they received the intervention protocols and materials.

CONCLUSIONS

Research is needed to develop and test worksite-based interventions to promote institutionalization, durability, and diffusion.

Multiplying health gains: the critical role of capacity-building within health promotion programs

Health outcomes in populations are the product of three factors: (1) the size of effect of the intervention; (2) the reach or penetration of an intervention into a population and (3) the sustainability of the effect. The last factor is crucial. In recent years, many health promotion workers have moved the focus of their efforts away from the immediate population group or environment of interest towards making other health workers and other organisations responsible for, and more capable of, conducting health promotion programs, maintaining those programs and initiating others. 'Capacity-building' by health promotion workers to enhance the capacity of the system to prolong and multiply health effects thus represents a 'value added' dimension to the health outcomes offered by any particular health promotion program. The value of this activity will become apparent in the long term, with methods to detect multiple types of health outcomes. But in the short term its value will be difficult to assess unless we devise specific measures to detect it. At present the term 'capacity-building' is conceptualised and assessed in different ways in the health promotion literature. Development of reliable indicators of capacity-building which could be used both in program planning and in program evaluation will need to take this into account. Such work will provide health-decision makers with information about program potential at the conclusion of the funding period, which could be factored into resource allocation decisions, in addition to the usual information about a program's impact on health outcomes. By program potential, we mean ability to reap greater and wider health gains.

The long-term effects of a cardiovascular disease prevention trial: the Stanford Five-City Project

OBJECTIVES

This study examined long-term effects of a health-education intervention trial to reduce the risk of cardiovascular disease.

METHODS

Surveys were conducted in California in two treatment and two control cities at baseline (1979/1980), after the 6-year intervention (1985/1986), and 3 years later at follow-up (1989/1990). Net treatment/control differences in risk-factor change were assessed for women and men 25 to 74 years of age.

RESULTS

Blood pressure improvements observed in all cities from baseline to the end of the intervention were maintained during the follow-up in treatment but not control cities. Cholesterol levels continued to decline in all cities during follow-up. Smoking rates leveled out or increased slightly in treatment cities and continued to decline in control cities but did not yield significant net differences. Both coronary heart disease and all-cause mortality risk scores were maintained or continued to improve in treatment cities while leveling out or rebounding in control cities.

CONCLUSIONS

These findings suggest that community-based cardiovascular disease prevention trials can have sustained effects. However, the modest net differences in risk factors suggest the need for new designs and interventions that will accelerate positive risk-factor change.
