NCT07227220

Brief Summary

The purpose of this proof-of-concept study is to assess the initial signal of effectiveness of summer youth employment programs (SYEP) on understudied obesity-related outcomes in adolescents. This small-scale study is essential to identify early success and refine the intervention before scaling to a larger, more resource-intensive randomized trial. Specifically, this one-group pre-posttest study will: Aim 1 (Primary): Evaluate if a 6-week SYEP provides an initial signal for effectiveness (maintenance or decrease in zBMI) over the summer. Hypothesis 1: Adolescents who participated in a SYEP will maintain or decrease their BMI over the summer. Aim 2 (Secondary): Evaluate changes in obesogenic behaviors (physical activity, sleep, sedentary, and diet) over the summer. Hypothesis 2: Adolescents who participated in a SYEP will increase physical activity, reduce sedentary behavior, and improve sleep and diet quality over the summer. Aim 3 (Secondary): Evaluate the feasibility of SYEP for obesity prevention intervention to inform intervention scalability. Hypothesis 3: The SYEP program will be a feasible and acceptable intervention strategy for the prevention of obesity in adolescents over the summer.

Outcome Measures

Primary Outcomes (1)

  • zBMI

    Height and weight will be directly measured by trained staff. Each measurement will be taken twice, and the average will be used for analysis. Changes in BMI will be expressed as Centers for Disease Control age-sex specific z-scores (zBMI).

    Baseline and Week 6 (post)

Secondary Outcomes (10)

  • Sedentary behaviors

Study Arms (1)

Summer Youth Employment Program

EXPERIMENTAL

Participants will work as junior summer camp counselors at a University of Houston camp, up to 24 hours/week, Monday-Thursday, 8:30 AM-3:30 PM (with a 12-1 PM lunch break), for six weeks from mid-June to the end of July. Participants will assist senior counselors with indoor/outdoor activities such as games, enrichment, and academics. On Fridays, from 10 AM to 12 PM, participants will attend professional development workshops on topics such as communication, teamwork, resume building, and job search skills. From 12-2:30 PM, undergraduate staff will lead social activities and mentoring.

Behavioral: Summer Youth Employment Program

Interventions

The intervention aims to employ adolescents in paid positions for six weeks during the summer, providing them with a structured, routine-based, and adult-supervised environment similar to that of the school year.
