Abstract

Context:

Faith-based health interventions may improve obesity-related health behaviors, including healthy eating and physical activity. However, the generalizability of results and comprehensiveness of reporting for critical design elements sufficient for large-scale implementation and broad public health impact are unclear. This review assesses the degree to which faith-based healthy eating and physical activity programs report intervention elements using the reach, effectiveness/efficacy, adoption, implementation, maintenance framework.

Evidence Acquisition:

A systematic literature search was initiated in June 2017, and updated searches concluded in December 2019. Articles were included if they (1) were published in an English language peer-reviewed journal, (2) were conducted in the U.S., (3) were interventions, (4) included individual-level healthy eating or physical activity behavioral outcomes, (5) were conducted within an organizational setting, and (6) were faith-based. Intervention elements were extracted, and comprehensiveness of reporting for intervention elements was assessed according to reach, effectiveness/efficacy, adoption, implementation, maintenance domains.

Evidence Synthesis:

A total of 38 interventions (46 articles) met the inclusion criteria. Most were conducted at the individual/interpersonal level (66%); few included additional elements of policy or environmental change (34%). Most interventions showed favorable changes in at least 1 health behavior outcome. No intervention addressed all reach, effectiveness/efficacy, adoption, implementation, maintenance indicators. The mean level of reporting was low for all reach, effectiveness/efficacy, adoption, implementation, maintenance dimensions (reach: 2.3 of 5 [SD=1.0] indicators, efficacy/effectiveness: 2.3 of 4 [SD=0.8] indicators, adoption: 3.7 of 6 [SD=1.4] indicators, implementation: 1.3 of 3 [SD=0.6] indicators, maintenance: 0.3 of 3 [SD=0.5] indicators).

Conclusions:

Studies reporting outcomes of faith-based interventions to improve healthy eating/physical activity behaviors lack the information necessary to understand the potential for broad dissemination and implementation in community settings. Future studies should report on the considerations for the translation and dissemination of evidence-based programs to expand public health impact.

Levels of Health Promotion and Illness Prevention

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...
