Cancer Prevention02:59

Cancer Prevention

6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Models of Health Promotion and Illness Prevention I

2.1K
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...

Models of Health Promotion and Illness Prevention II

1.6K
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...

Levels of Health Promotion and Illness Prevention

12.8K
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...

Diabetes Mellitus: Type 2 and Gestational

2.6K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

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.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Area of Science:

  • Digital Health Interventions
  • Behavior Change Theory
  • Maternal Health

Background:

  • Healthy diet and physical activity (PA) during pregnancy improve maternal and fetal outcomes.
  • Digital interventions offer a cost-effective and accessible approach to behavior change.
  • The Baby Buddy app is a widely used platform for supporting parents in the UK.

Purpose of the Study:

  • To develop a theory-based intervention within the Baby Buddy app.
  • To empower expectant parents to adopt healthier dietary and PA habits.
  • To support healthy behaviors throughout pregnancy and parenthood.

Main Methods:

  • Utilized the Behavior Change Wheel and a person-based approach for intervention design.
  • Conducted three stages of qualitative research with pregnant and recently pregnant parents.
  • Incorporated iterative feedback from users, patient involvement, and expert contributors.

Main Results:

  • Confirmed the appeal and relevance of the intervention concept, including partner involvement.
  • Refined intervention design based on iterative feedback, ensuring relevance for a diverse audience.
  • Identified and addressed functionality, content, and design issues to enhance user experience.

Conclusions:

  • Combining theoretical methods with a person-based approach yields user-friendly and engaging interventions.
  • The developed intervention is theory-based, user-friendly, appealing, and engaging.
  • Further research is required to assess the intervention's effectiveness on diet, PA, and weight management.
