Basic Information

Brief Summary

The investigators propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 48 overweight/obese Hispanic males ages 18-64 over 12 weeks; 2) assess participant characteristics and process measures related to the uptake of mobile-health (mHealth) technology in overweight/obese Hispanic males over 12 weeks; and 3) assess pathologic changes in the liver in Hispanic men enrolled in a 12-week weight loss intervention using a non-invasive MRI as a therapeutic response biomarker.

Detailed Description

In the U.S., Hispanic males have the highest rate of overweight and obesity when compared to males of other racial/ethnic groups placing them at greater risk for obesity-related disease. Yet, current literature is lacking to inform on best practices to engage Hispanic males in weight loss and/or to promote a successful weight loss trajectory. Without this information the health disparities associated with obesity and obesity-related chronic disease will continue. Evidence exists to support behavioral weight loss in reducing obesity-related health risks. There are limited data to suggest these programs are effective for men and no data to support the feasibility and effectiveness of these programs among Hispanic males despite this being the fastest growing and highest burdened group for obesity-related disease within the U.S. population. Using existing practice guidelines and evidence from recently completed in-depth qualitative interviews in overweight/obese Hispanic males, the investigators will test a novel intervention approach to address this gap in knowledge. The investigators propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 48 overweight/obese Hispanic males ages 18-64 over 12 weeks; 2) assess participant characteristics and process measures related to the uptake of mobile-health (mHealth) technology in overweight/obese Hispanic males over 12 weeks; and 3) assess pathologic changes in the liver in Hispanic men enrolled in a 12-week weight loss intervention using a non-invasive MRI as a therapeutic response biomarker. This project will challenge current research paradigms for Hispanic males by testing a gender- and culturally-sensitive weight loss intervention and providing highly impactful formative research on the use of novel mHealth self-monitoring technologies to facilitate dietary/physical activity behavior changes. Given the Hispanic population is the fastest growing in the U.S., efforts to identify strategies to promote weight control among Hispanic males has potential to significantly impact public health. The expected outcome of the proposed project is the identification of feasible and appropriate weight loss intervention strategies to improve engagement and weight management in this vulnerable ethnic group.

Study Groups

Intervention

Includes changing eating behaviors, increasing physical activity, and attending regular in-person weight loss meetings for 12 weeks. To support additional weight loss/weight maintenance, participants will receive bi-weekly phone calls across a 12 week follow-up.

Group Type: EXPERIMENTAL

Counseling sessions

Intervention Type: BEHAVIORAL

During the first 12 weeks, intervention participants will attend weekly 30-45-minute individual counseling sessions guided by a trained bilingual Hispanic male lifestyle coach. Counseling sessions will be tailored to the needs of the participants (e.g., evening/weekend sessions, waiting/childcare area). After 12 weeks, intervention group participants will receive bi-weekly phone calls across a 12-week follow-up. Phone calls will last approximately 10 minutes in duration and study staff will follow a script to review current body weight, eating and activity behaviors, and specific barriers for weight loss/maintenance or diet/physical activity behaviors.

Wait List Control

Wait-list control participants will not receive any intervention for the first 12 weeks. After 12 weeks, participants will receive the weight loss intervention plus mHealth technology support.

Group Type: OTHER

Wait List Control

Intervention Type: BEHAVIORAL

After 12 weeks, the wait list control will receive the weight loss intervention plus mHealth technology support. It will include tailored, targeted text messaging and real-time self-monitoring support including beverage tracking cups, which provide the amount of calories users are consuming through beverages on a daily basis, and wearable activity monitors.Behavioral constructs used for the intervention group will be maintained during this intervention delivery thereby ensuring all participants have the appropriate tools to continue weight loss efforts regardless of mHealth use.

Eligibility Criteria

Inclusion Criteria

• 18-64 years of age
• BMI between 25 to 45.0 kg/m² (NOTE: The investigators elected to cap this at 45.0 kg/m² to minimize potential risks and to reduce the potential for obesity to limit exercise participation)
• Ability to provide informed consent and health risk assessment prior to participation in this study
• Speak, read, and write either English and/or Spanish

Exclusion Criteria

• Uncontrolled diabetes mellitus
• History of bariatric surgery
• Report medical condition or treatment for a medical condition that could affect body weight or ability to engage in structured physical activity that is consistent with the intervention for this study
• Current congestive heart failure, angina, uncontrolled arrhythmia, or other symptoms indicative of an increased acute risk for a cardiovascular event
• Resting systolic blood pressure of ≥150 mmHg or resting diastolic blood pressure of ≥90 mmHg
• Eating disorders that would contraindicate weight loss or physical activity
• Alcohol or substance abuse
• Currently treated for psychological issues (i.e. depression, bipolar disorder, etc.), taking psychotropic medications with the previous 12 months, or hospitalized for depression within the previous 5 years
• Report exercise on ≥3 days per week for ≥ 20 minutes per day over the past 3 months
• Report weight loss of ≥5% or participating in a weight reduction diet program in the past 3 months
• Report plans to relocate to a location that limits their access to the study site or having employment, personal, or travel commitments that prohibit attendance to all of the scheduled assessments
