Challenge! Adolescent Obesity Prevention (Challenge)

August 14, 2019 updated by: Maureen Black, University of Maryland, Baltimore

Challenge! in Baltimore City Middle Schools

The prevalence of overweight among adolescents (BMI-for-age %tile over the 95th percentile) has more than tripled over the past 3 decades in the US. Overweight and physical inactivity disproportionately affect low- income, female, African American adolescents.

A prior health-promotion/ obesity-prevention program for adolescents developed and tested by our group (Challenge!) showed that adolescents who received the intervention were less likely to become overweight or obese over 2 years when compared to the control group. This intervention was administered one-on-one to adolescents in their homes or community by a college-aged mentor.

Schools are an ideal setting for interventions because the effect can be far-reaching and sustainable. School-based obesity-prevention interventions have thus far shown modest results.

The purpose of this study is to evaluate the impact of a multilevel intervention that includes both the Challenge program administered in a small group format after school using mentors and teachers and a school-wide environmental change on adolescent females' body composition, diet, and physical activity. The intervention is targeted to 6th and 7th grade female students. The small group intervention is conducted over 12 weeks and includes goal setting focusing on healthy diet and physical activity, along with membership and weekly trips to the YMCA. The environmental intervention includes a Health and Activity Committee (HAC), comprised of 8th grade female students (popular opinion leaders), school personnel, parents, and community members. The HAC develops school-wide health promotion messages and activities. Parents of participating 6th and 7th grade girls provide information on family variables. The hypotheses are that females who receive the small group or environmental intervention are at less risk of weight gain (overweight) than females in the control small group condition, that females in environmental schools are at less risk of weight gain (overweight) than females in the control environmental condition, and that females who receive both the small group and environmental intervention are at the lower risk of weight gain (overweight) than females who receive only the environmental or small group intervention or neither intervention.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

10 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Experimental: Challenge! Small Group Intervention only

This group receives the Challenge! Small Group intervention consisting of curriculum related to health behavior goal setting, healthy eating, and staying active, works out with their Health Educators, and receives a year-long membership to the YMCA.

This group is in schools that were randomly assigned to NOT receive the Environmental Intervention.
Behavioral: Challenge! Small Group Intervention
The Challenge! Small Group intervention consists of curriculum related to health behavior goal setting, healthy eating, and staying active, working out with Health Educators, and receiving a year-long membership to the YMCA.

The environmental intervention involves the formation of a Health and Activity Committee composed of community members, teachers, parents, school staff, and 8th grade girls from the school. Together, this group comes up with ways to make their school environment healthier.
