About this study

Official title: Family Lifestyle Overweight Prevention Program: Evaluation of a Weight Management Program for Mexican American Youth

The purpose of the study was to design a weight management program for Mexican American youth and to determine the effectiveness of the program for weight management compared to a self help program.

  1. At the end of 6 months, individuals randomly assigned to Intensive Intervention (II) (instructor/trainer led intervention) will lose more weight than individuals assigned to Self Help (SH) only.
  2. At the end of 1 year, individuals randomly assigned to II will maintain their weight losses better than individuals assigned to SH.

Secondary hypotheses will include examination of main effects and interactions at the end of 6 months with the following secondary dependent measures: treatment adherence (e.g., attendance, food diaries, exercise diaries), blood levels, changes in percent body fat, overall psychological functioning (PEDS-QL 4.0), and eating behaviors as assessed by food frequency checklists.

Read the detailed description

The overall objective of this study is to compare the effectiveness of a behavioral, family-based weight management program and a self-help only group for the prevention of obesity in adolescents. The treatments are; Self Help(SH) Instructions to follow a 12-week self help manual for healthy eating and increased physical activity; Intensive Intervention (II) 12 Weeks of daily and 7 Monthly sessions consisting of nutrition instruction, physical activity training, and behavior modification instruction. One hundred (BMI-for-age = 85th - 97.5th % or parent BMI > 25) adolescent males and females will be recruited into the study and randomly assigned to SH) Instructions to follow the self help manual for healthy eating and increased physical activity; II) 12 Weeks daily and 7 Monthly sessions consisting of nutrition instruction, physical activity training, and behavior modification instruction for one year. Participants will receive final measurements at the end of year 1 and intermediate evaluations at month 6. Given that the interventions decline in intensity and frequency after 3 months, the 1 year assessments will help evaluate which treatment was most effective in maintaining weight losses with minimal contact.

SH will consist of participants being instructed to follow a 12-week parent/child based self help book for weight loss, but they will not receive any active intervention. The manual (TRIM Kids, Sothern, von Almen, \& Schumacher, 2001) that the families will follow is a treatment program which uses a family-based, behavioral intervention that focuses on diet and exercise with instructions and guidelines designed to assist the family in maintaining weight losses. II will consist of 12 Weeks of daily and 7 Monthly sessions consisting of nutrition instruction, physical activity training, and behavior modification instruction over the 1-year period. Body mass index (BMI), blood analyses (i.e. cholesterol, triglycerides, insulin, glucose, C-reactive protein, mono-unsaturated fatty acids, and inflammatory cytokines), analysis of eating and exercise behavior, and eating and exercise self-efficacy measures will be taken throughout the study. The focus of this study is to evaluate the effectiveness of an active, behaviorally designed intervention for the prevention of adult obesity.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing FLOW and SelfHelp in people with Overweight and Obesity, run by Baylor College of Medicine.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

standardized body mass index (zbmi). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00454610, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2017; AzTrials last refreshed its copy on 26 Oct 2026.
