Models of Health Promotion and Illness Prevention II

2.3K
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...

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 I

3.1K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age

340
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Aging

1.1K
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Area of Science:

  • Gerontology and Occupational Health
  • Digital Health Interventions
  • Behavioral Science in the Workplace

Background:

  • Workers aged 50+ face higher chronic disease risks.
  • Internet-based health promotion programs show efficacy.
  • Older workers are a key demographic for targeted health initiatives.

Purpose of the Study:

  • To evaluate the effectiveness of the HealthyPast50 web-based program.
  • To assess health practice improvements in workers aged 50 and older.
  • To utilize social cognitive theory in an automated online health promotion.

Main Methods:

  • Randomized controlled trial with 278 employees (ages 50-68).
  • Comparison between HealthyPast50 program and wait-list control.
  • Online self-report measures (diet, physical activity, stress, tobacco use) collected pre- and post-intervention; intent-to-treat analysis with multiple imputation.

Main Results:

  • Program group showed significant improvements in diet self-efficacy and planning, and mild exercise.
  • Additional significant effects found in eating practices, exercise self-efficacy/planning, and aging beliefs in complete case analysis.
  • Gender moderated exercise effects, suggesting greater impact among women.

Conclusions:

  • The HealthyPast50 web-based program demonstrates potential for short-term improvements in diet and exercise among older workers.
  • Online health promotion is a viable strategy for this demographic.
  • Program effects on exercise were more pronounced in women.
