What You Need to Know Before You Apply

What is the purpose of this trial?

Mexican American families share similar elevated risks for obesity and obesity-related conditions, such as type 2 diabetes. Because negative family interactions and relationships (e.g., poor communication, high conflict, low emotional closeness) are associated with obesity treatment outcomes, this study tests a behavioral weight management intervention that provides relationship skills counseling to mothers and adult daughters. The goal is to improve family interaction patterns to buffer challenges and strengthen collaboration for eating and physical activity behaviors that support long-term weight management and thus provide an effective obesity treatment approach to address a major public health concern.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the Family-Based Obesity Intervention for Mexican Americans safe for participants?

The studies reviewed suggest that behavioral weight management interventions, including those with relationship skills training, are generally safe for participants. No specific safety concerns were reported in the studies involving Mexican American populations.12345

How does the Family-Based Obesity Intervention for Mexican Americans differ from other treatments for obesity?

This treatment is unique because it combines standard behavioral weight management with relationship skills training, emphasizing family involvement and cultural sensitivity, which has shown to be more effective for weight loss in Mexican Americans compared to individual-focused approaches.14567

What data supports the effectiveness of the treatment for obesity in Mexican Americans?

Research shows that culturally adapted behavioral weight-loss programs for Mexican American women can lead to significant weight loss and improved family relationships, which are linked to better weight management outcomes. A study found that adding relationship skills training to standard behavioral treatment resulted in greater weight loss and improved family dynamics.24589

Published Research Related to This Trial

The study applied the Transtheoretical Model of Behavior Change to a sample of Mexican American women in a weight-loss program, identifying five distinct profiles of change that align with previous research in other behavioral contexts.
Although the sample size was small, the findings support the effectiveness of the Transtheoretical Model for understanding weight-loss behaviors in Hispanic populations, highlighting the need for more inclusive future research.

A core outcome set for behavioral weight management programs (BWMPs) is being developed to standardize how outcomes are reported, allowing for better comparison of different interventions for adults with overweight and obesity.
The study will utilize a Delphi process involving 40 experts to reach consensus on which outcomes to measure and the definitions or instruments to use, ensuring that the findings are relevant and applicable in real-world settings.

A culturally-adapted weight-loss program for obese Spanish-speaking Mexican women was successfully implemented, with 47 participants and a focus on group activities and Mexican traditions over 12 months.
Participants achieved a mean weight loss of 7.2 kg and a BMI reduction of 5.5 kg/m² by the end of the study, demonstrating the efficacy of the intervention in promoting weight loss in this population.
