简要总结
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.
详细描述
Preliminary evidence suggests that summer employment can be an age-appropriate, structured intervention to prevent unhealthy changes in obesogenic behaviors among adolescents. While these findings are promising, none of the existing studies have measured changes in BMI over the summer or conducted comprehensive assessments of obesogenic behaviors, including diet, sedentary behavior, sleep, and physical activity. To address these gaps, this study proposes a small proof-of-concept study to assess the initial signal of effectiveness on understudied obesity-related outcomes in adolescents.
SYEPs are well-established, continuously operating initiatives over 60 years with proven benefits in academics, workforce development, and crime prevention, and may also act as obesity prevention strategies. Rather than creating new interventions, investing in and expanding access to SYEPs-programs with high demand yet limited capacity (with only ~28% of applicants matched with jobs each summer, leaving the majority on waitlists)-can offer a practical solution for youth obesity prevention.

研究组 & 干预措施
Summer Youth Employment Program
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.

结局指标
主要结局
Change in Age- and Sex-Specific Body Mass Index (BMI)-For-Age Z-Score (zBMI) From Baseline to Week 6
时间窗: Baseline and Week 6 (post)
Height and weight will be directly measured by trained staff. Each measurement will be taken twice, and the average will be used for analysis. Body mass index (BMI) will be calculated and expressed as Centers for Disease Control and Prevention (CDC) age- and sex-specific BMI-for-age z-scores (zBMI). The outcome will represent the change in zBMI from baseline to Week 6. A positive change score will indicate an increase (gain) in zBMI from baseline to Week 6, which will be considered a less favorable outcome. A negative change score will indicate a decrease in zBMI, which will be considered a favorable outcome. A change score of 0 will indicate no change in zBMI (maintenance), which will also be considered a favorable outcome for this intervention because preventing excess BMI gain during summer is a primary goal.
