Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Levels of Health Promotion and Illness Prevention01:26

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...

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome is...

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 from...

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...
Primary Healthcare Services01:30

Primary Healthcare Services

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Summary
This summary is machine-generated.

Multi-component community interventions for physical activity show inconsistent results. Methodological issues in studies mean current evidence does not support their effectiveness in increasing population physical activity levels.

Area of Science:

  • Public Health
  • Health Promotion
  • Epidemiology

Background:

  • Community-wide interventions for physical activity are popular but their population-level impact remains unclear.
  • Evaluating the effectiveness of multi-strategic approaches to increase physical activity is crucial for public health initiatives.

Purpose of the Study:

  • To assess the impact of community-wide, multi-strategic interventions on population levels of physical activity.
  • To synthesize evidence from rigorous study designs on the effectiveness of physical activity interventions.

Main Methods:

  • A comprehensive search of multiple databases and grey literature was conducted up to November 2009.
  • Included studies were cluster randomized controlled trials, RCTs, quasi-experimental designs, interrupted time-series, and prospective controlled cohort studies with at least six-month follow-up.
  • Data extraction and risk of bias assessment were performed independently by at least two authors, with outcomes analyzed using risk differences and relative risks.

Main Results:

  • Twenty-five studies were included, with 19 from high-income and six from low-income countries.
  • Fifteen studies had a high risk of bias, primarily due to selection bias, with only one study using community randomization.
  • Intervention effects were inconsistent, and some well-designed studies showed no improvement in physical activity levels; publication bias was also evident.

Conclusions:

  • Significant methodological limitations and inconsistencies in findings confound the evidence.
  • The current body of evidence does not support the effectiveness of multi-component, community-wide interventions for increasing population physical activity.
  • Future research requires well-designed studies focusing on measurement quality, frequency, and appropriate allocation to intervention and control groups.
