Cancer Survival Analysis01:21

Cancer Survival Analysis

383
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

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 II01:18

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

12.7K
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...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

352
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

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...

Area of Science:

  • Public Health
  • Health Disparities
  • Cancer Prevention

Background:

  • Health equity significantly impacts cancer screening, treatment, and mortality rates.
  • Systematic review to identify and evaluate video/DVD interventions for reducing cancer screening inequities.

Approach:

  • Searched major databases (PubMed, Web of Science, Embase, Cochrane) for randomized control trials (RCTs) up to January 2023.
  • Included studies comparing video interventions against usual care, focusing on cancer screening uptake.
  • Assessed risk of bias using the Cochrane Collaboration tool.

Key Points:

  • 18 RCTs analyzed, focusing on colorectal, cervical, breast, and prostate cancer screening.
  • Most interventions were US-based, targeting ethnic/racial minorities and low-income groups.
  • Culturally tailored or emotive videos were more effective than information-only formats, especially for cervical cancer screening.

Conclusions:

  • Video interventions offer potential benefits for increasing cancer screening in underserved populations, but results are variable.
  • Individual and cultural tailoring of educational materials is crucial for intervention effectiveness.
  • Further research outside the USA is recommended to explore broader applicability.
