Characteristics of interventions targeting multiple lifestyle risk behaviours in adult populations: a systematic scoping review

BACKGROUND

Modifiable lifestyle risk behaviours such as smoking, unhealthy diet, physical inactivity and alcohol misuse are the leading causes of major, non-communicable diseases worldwide. It is increasingly being recognised that interventions which target more than one risk behaviour may be an effective and efficient way of improving people's lifestyles. To date, there has been no attempt to summarise the global evidence base for interventions targeting multiple risk behaviours.

OBJECTIVE

To identify and map the characteristics of studies evaluating multiple risk behaviour change interventions targeted at adult populations in any country.

METHODS

Seven bibliographic databases were searched between January, 1990, and January/ May, 2013. Authors of protocols, conference abstracts, and other relevant articles were contacted. Study characteristics were extracted and inputted into Eppi-Reviewer 4.

RESULTS

In total, 220 studies were included in the scoping review. Most were randomised controlled trials (62%) conducted in the United States (49%), and targeted diet and physical activity (56%) in people from general populations (14%) or subgroups of general populations (45%). Very few studies had been conducted in the Middle East (2%), Africa (0.5%), or South America (0.5%). There was also a scarcity of studies conducted among young adults (1%), or racial and minority ethnic populations (4%) worldwide.

CONCLUSIONS

Research is required to investigate the interrelationships of lifestyle risk behaviours in varying cultural contexts around the world. Cross-cultural development and evaluation of multiple risk behaviour change interventions is also needed, particularly in populations of young adults and racial and minority ethnic populations.

A systematic review of selected interventions for worksite health promotion. The assessment of health risks with feedback

BACKGROUND

Many health behaviors and physiologic indicators can be used to estimate one's likelihood of illness or premature death. Methods have been developed to assess this risk, most notably the use of a health-risk assessment or biometric screening tool. This report provides recommendations on the effectiveness of interventions that use an Assessment of Health Risks with Feedback (AHRF) when used alone or as part of a broader worksite health promotion program to improve the health of employees.

EVIDENCE ACQUISITION

The Guide to Community Preventive Services' methods for systematic reviews were used to evaluate the effectiveness of AHRF when used alone and when used in combination with other intervention components. Effectiveness was assessed on the basis of changes in health behaviors and physiologic estimates, but was also informed by changes in risk estimates, healthcare service use, and worker productivity.

EVIDENCE SYNTHESIS

The review team identified strong evidence of effectiveness of AHRF when used with health education with or without other intervention components for five outcomes. There is sufficient evidence of effectiveness for four additional outcomes assessed. There is insufficient evidence to determine effectiveness for others such as changes in body composition and fruit and vegetable intake. The team also found insufficient evidence to determine the effectiveness of AHRF when implemented alone.

CONCLUSIONS

The results of these reviews indicate that AHRF is useful as a gateway intervention to a broader worksite health promotion program that includes health education lasting > or =1 hour or repeating multiple times during 1 year, and that may include an array of health promotion activities. These reviews form the basis of the recommendations by the Task Force on Community Preventive Services presented elsewhere in this supplement.

The association between health risk change and presenteeism change

OBJECTIVE

This prospective study investigates whether changes in health risks are associated with changes in presenteeism (on-the-job productivity loss).

METHOD

A total of 7026 employees of a national financial services company responded to a health risk appraisal (HRA), which included a modified version of the Work Limitation Questionnaire (WLQ) in both 2002 and 2004. The association between changes in health risks and changes in self-reported presenteeism was examined.

RESULTS

Changes in perceptual/psychologic health risks had a strong association with changes in presenteeism. Individuals who reduced their risks generally saw an improvement in productivity, whereas those who gained risks or remained high-risk status saw deterioration in productivity. Each risk factor increased or reduced was associated with a commensurate change in 1.9% productivity loss over time and estimated to be 950 dollars per year per risk changed.

CONCLUSIONS

Positive and negative changes in health risks are associated with same-direction changes in presenteeism.

Heart healthy and stroke free: successful business strategies to prevent cardiovascular disease

BACKGROUND

Heart disease and stroke, the principal components of cardiovascular disease (CVD), are the first and third leading causes of death in the United States. In 2002, employers representing 88 companies in the United States paid an average of 18,618 dollars per employee for health and productivity-related costs. A sizable portion of these costs are related to CVD.

RESULTS

Employers can yield a 3 dollar to 6 dollar return on investment for each dollar invested over a 2 to 5 year period and improve employee cardiovascular health by investing in comprehensive worksite health-promotion programs, and by choosing health plans that provide adequate coverage and support for essential preventive services. The most effective interventions in worksites are those that provide sustained individual follow-up risk factor education and counseling and other interventions within the context of a comprehensive health-promotion program: (1) screening, health risk assessments, and referrals; (2) environmental supports for behavior change (e.g., access to healthy food choices); (3) financial and other incentives; and (4) corporate policies that support healthy lifestyles (e.g., tobacco-free policies). The most effective practices in healthcare settings include systems that use (1) standardized treatment and prevention protocols consistent with national guidelines, (2) multidisciplinary clinical care teams to deliver quality patient care, (3) clinics that specialize in treating/preventing risk factors, (4) physician and patient reminders, and (5) electronic medical records.

CONCLUSIONS

Comprehensive worksite health-promotion programs, health plans that cover preventive benefits, and effective healthcare systems will have the greatest impact on heart disease and stroke and are likely to reduce employers' health and productivity-related costs.

A prescribed employee fitness program and job-related attitudes

A prescribed physical fitness exercise program was initiated in a small furniture manufacturing plant. The present purpose was to investigate the effect of an intervention to change employees' attitudes and sense of well-being. The objective was to evaluate the changes in employees' attitudes (well-being) attributable to the exercise program. The method of evaluation was the survey administered to a treatment (n = 22) and a mixed (n = 30) control group. A multidimensional attitude survey questionnaire was administered to assess effects over a 6-mo. period. While some changes in job attitudes were observed for the treatment group, those were not the expected changes. Possible explanations for the findings are discussed.

A review and analysis of the clinical and cost-effectiveness studies of comprehensive health promotion and disease management programs at the worksite: 1995-1998 update (IV)

The fourth in a series of critical reviews, this study examines the clinical and cost outcome evaluations of 10 worksite health promotion programs that were comprehensive, multifactorial, and directed at risk management. The studies, conducted between 1994 and 1998, indicate favorable clinical and cost outcomes and suggest characteristics of worksite interventions that may be critical for effectiveness.

Worksite physical activity interventions

BACKGROUND

National objectives for public health have targeted worksite as important settings for interventions to increase physical activity. However, expert reviews reveal no scientific consensus about the effectiveness of worksite interventions for increasing physical activity or fitness.

METHODS

We judged the quantity and quality of existing evidence against scientific standards for the internal and external validity of the research design and the validity of measurements. Meta-analytic methods were used to quantify the size of effects expressed as Pearson correlation coefficients (r). Variation in effect was examined in relation to several features of the studies deemed important for implementing successful worksite interventions. Pre-experimental cohort studies were excluded because they are sensitive to secular trends in physical activity.

RESULTS

Twenty-six studies involving nearly 9,000 subjects yielded 45 effects. The mean effect was heterogeneous and small, r = 0.11 (95% CI, -0.20 to 0.40), approximating 1/4 S.D., or an increase in binomial success rate from 50% to 56%. Although effects varied slightly according to some of the study features we examined, effects were heterogeneous within levels of these features. Hence, the moderating variables examined did not explain variation in the effects (P > 0.05). The exception was that effects were smaller in randomized studies compared with studies using quasi-experimental designs (P < 0.05).

CONCLUSIONS

Our results indicate that the typical worksite intervention has yet to demonstrate a statistically significant increase in physical activity or fitness. The few studies that have used an exemplary sample, research design, and outcome measure have also yielded small or no effects. The generally poor scientific quality of the literature on this topic precludes the judgment that interventions at worksites cannot increase physical activity or fitness, but such an increase remains to be demonstrated by studies using valid research designs and measures.

Worksite health promotion programs in the U.S.: factors associated with availability and participation

PURPOSE

To examine how the availability of and participation in worksite health promotion programs varies as a function of individual (e.g., age), organizational (e.g., occupation), and health (e.g., high blood pressure) characteristics. Availability of worksite programs was also compared to that reported in two previous national surveys of private companies.

DESIGN

Data analyzed were from the 1994 National Health Interview Survey (NHIS), a national cross-sectional probability sample of the U.S. civilian population.

SUBJECTS

Five thousand two hundred nineteen NHIS respondents met the inclusion criteria of (1) being currently employed in a company of at least 50 employees, and (2) completing the NHIS section on worksite health promotion.

MEASURES

Employees indicated the availability of, and their participation in, 33 different types of worksite programs. National Health Interview Survey data were also available regarding general health, blood pressure, body mass index, and medical conditions.

RESULTS

Smoking cessation programs had the highest mean availability (43%), followed by health education programs (31%) and screening tests (31%). Overall, availability of worksite programs appeared comparable to that reported in a recent national survey. Participation ranged from 32% for health education programs to 5% for smoking cessation programs. Compared to availability, participation depended less on individual and organizational characteristics. Healthy employees were not consistently more likely to participate in worksite health promotion programs than nonhealthy employees.

CONCLUSIONS

Although availability of worksite health promotion programs remains high, participation by employees in specific types of programs can vary widely. Attempts to increase participation should look beyond individual, health, and organizational variables, to specific features of the work environment that encourage involvement in health promotion activities.

Clinical and cost outcomes of multifactorial, cardiovascular risk management interventions in worksites: a comprehensive review and analysis

This paper is a critical review of the clinical and cost outcome evaluation studies of multifactorial, comprehensive, cardiovascular risk management programs in worksites. A comprehensive international literature search conducted under the auspices of the National Heart, Lung and Blood Institute identified 17 articles based on 12 studies that examined the clinical outcomes of multifactorial, comprehensive programs. These articles were identified through MEDLINE, manual searches of recent journals, and through direct inquiries to worksite health promotion researchers. All studies were conducted between 1978 and 1995, with 1978 being the date of the first citation of a methodologically rigorous evaluation. Of the 12 research studies, only 8 utilized the worksite as both the unit of assignment and as the unit of analysis. None of the studies analyzed adequately for cost effectiveness. Given this limitation, this review briefly considers the relevant worksite research that has demonstrated cost outcomes. Worksite-based, multifactorial cardiovascular intervention programs reviewed for this article varied widely in the comprehensiveness, intensity, and duration of both the interventions and evaluations. Results from randomized trials suggest that providing opportunities for individualized, cardiovascular risk reduction counseling for high-risk employees within the context of comprehensive programming may be the critical component of an effective worksite intervention. Despite the many limitations of the current methodologies of the 12 studies, the majority of the research to date indicates the following: (1) favorable clinical and cost outcomes; (2) that more recent and more rigorously designed research tends to support rather than refute earlier and less rigorously designed studies; and (3) that rather than interpreting the methodological flaws and diversity as inherently negative, one may consider it as indicative of a robust phenomena evident in many types of worksites, with diverse employees, differing interventions, and varying degrees of methodological sophistication. Results of these studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and insights regarding the essential components and characteristics of successful programs.

The financial impact of changes in personal health practices

The impact of changes in health practices on medical claims costs between 1985-1987 and 1988-1990 was examined among 796 employees. Employees completed a health risk appraisal in 1985 and 1988 and were categorized into health risk levels. High-cost status and high-risk status were significantly associated at both times. The percentage of employees with high-risk status decreased from 31.8% to 25.3% between 1985 and 1988 (P < 0.01). Changes in average costs and the percentage with high-cost status followed the risk change. The largest increase in average costs occurred in employees who moved from low-risk to high-risk status. The greatest reduction in average costs occurred in employees who moved from high-risk to low-risk status. Median costs were not as sensitive to risk change. The findings provide strong evidence that improving individual health status is associated with financial benefits.

A review of health-related outcomes of multi-component worksite health promotion programs

PURPOSE

The purpose of this article is to critically review evaluation studies of the health-related effects (i.e., health risk modification and reduction in worker absenteeism) of multicomponent worksite health promotion programs.

SEARCH METHOD

A comprehensive literature search conducted under the auspices of the Centers for Disease Control and Prevention identified 36 articles that examined health-related outcomes of multi-component programs. The authors identified 11 additional articles through manual searches of recent journal issues and through personal contacts with worksite health promotion researchers. Forty-seven studies describing the results of 35 worksite health promotion programs were reviewed.

IMPORTANT FINDINGS

The worksite health promotion programs reviewed for this article varied tremendously in the comprehensiveness, intensity, and duration of the intervention activities. All of the programs provided health education to employees. In a majority of the programs, opportunities to learn and practice new skills were also offered. A smaller number of programs incorporated modifications in organizational policy or the physical work environment. Results from well-conducted randomized trials suggest that providing opportunities for individual risk reduction counseling for high risk employees within the context of comprehensive programming may be the critical component of an effective worksite health promotion program. Just offering low intensity, short duration programs aimed at increasing awareness of health issues for the entire employee population may not be sufficient to achieve desired outcomes.

MAJOR CONCLUSIONS

The results of the studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and some general guidance as to the critical components and characteristics of successful programs. Overall, the evidence suggests that a rating of indicative/acceptable may best characterize this literature.

Obstacles to community health promotion

The health transition ushered into the world in this century calls for a reorientation of traditional health services to manage the new causes of morbidity and mortality, renewing interest in disease prevention and health promotion. Community-based health promotion emphasizes prevention and community participation with people's empowerment to overturn current inequities and increase control over their health. Encouraged worldwide by the World Health Organization for the last two decades, some community health promotion programs have been implemented and lessons learned. However, the shift in focus required means nothing less than a paradigm change demanding not only a reorientation of professional training, but also a reorganization of social structures in communities. This article discusses nine of the interrelated obstacles that must be overcome to further develop community health promotion.
