Summary
Mobile health (mHealth) interventions using behavior change techniques (BCTs) are highly acceptable for cancer survivors with overweight or obesity. This approach supports lifestyle changes and psychological adjustment post-treatment.
Area of Science:
- Oncology
- Behavioral Science
- Digital Health
Background:
- Many cancer survivors experience overweight or obesity, negatively impacting health.
- Weight management is often overlooked in standard oncology aftercare.
- Mobile health (mHealth) combined with behavior change techniques (BCTs) shows promise for lifestyle modification in this population.
Purpose of the Study:
- To assess the acceptability of an mHealth-based behavior change intervention for cancer survivors with a BMI ≥ 25.
- To gather participant feedback for intervention refinement.
Main Methods:
- An 8-week intervention combining educational sessions and physical activity goal setting via mobile technology (Fitbit, SMS).
- Utilized a randomized controlled trial design with semistructured interviews and a quantitative survey.
- Thematic analysis of qualitative data and statistical analysis of survey responses.
Main Results:
- High acceptability reported, with 97% of survey respondents holding a positive attitude.
- mHealth components (Fitbit, SMS goal setting) were particularly well-received.
- Participants perceived high efficacy (94%) for improving health and well-being, with understanding extending beyond weight management.
Conclusions:
- The mHealth and BCT intervention is acceptable for overweight/obese cancer survivors.
- Participants recommended incorporating social support.
- Further research is needed on clinical feasibility and provider acceptability.

01:21Cancer Survival Analysis
523
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...

02:59Cancer Prevention
7.2K
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.

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:18Models 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.

919
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

01:15Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
