Brief summary

Using a previously created weight management program for adolescents, the intervention will be implemented through school-based health centers (SBHC) and will be delivered by SBHC providers trained in Motivational Interviewing. Students at intervention school sites will be compared to students at control school sites. All students will have baseline, 1 year, and 2 year follow-up to assess if students in the intervention school sites will have improved risk factor profile for metabolic syndrome, improved nutrition and increased physical activity when compared with students at control school sites.

Interventions

BEHAVIORALACTION PAC

School-based health center providers will use motivational interviewing to assist students with adopting strategies for improving nutrition and increasing physical activity. All participants will receive annual BMI and other health results discussion with clinical providers. Adolescents with overweight/obesity will meet with providers for 16 sessions over 2 years.

BEHAVIORALCommunication with parents

A letter containing BMI and other health results and obesity prevention recommendations will be sent to parent/guardians.

Change in Reported Added Sugar IntakeBaseline to two yearsReported change in added sugar intake as measured by the Block Kids Food Screener-Last Week for Ages 2-17 for students who had a baseline BMI \<85th percentile and endline data

Change in BMI Z-scoreBaseline to two yearsChange in body-mass index (BMI; weight in kilograms divided by the square of the body height in meters) Z-score for students who had a baseline BMI \>= 85th percentile (overweight or obese) and endline data. A Z-score of 0 represents the population mean. A Z-score above 2 indicates obesity (BMI \>2 standard deviations above the mean) in children and teens. A decline in BMI Z-score would be a positive outcome in this weight management study.
Change in HOMA-IRBaseline to two yearsChange in Homeostatic Model Assessment for Insulin Resistance (HOMA-IR; insulin resistance index) for students who had a baseline BMI \>= 85th percentile (overweight or obese) and endline data. HOMA-IR is calculated using the formula: (fasting glucose \[mg/dL\] x fasting insulin \[microU/mL\])/405. HOMA-IR values \>2 indicate insulin resistance. A decrease in HOMA-IR would be a positive outcome.

Participant flow

Recruitment details

Participants were enrolled from February 2014 to November 2015. Participants were recruited during general school registration events, the classes or practices of interested teachers, and lunch time.

Pre-assignment details

Teens were excluded based on assessments at the baseline visit: blood pressure in the range of stage 2 hypertension or a score of ≥20 on the Eating Attitudes Test.

Change in BMI Z-score

Change in body-mass index (BMI; weight in kilograms divided by the square of the body height in meters) Z-score for students who had a baseline BMI \>= 85th percentile (overweight or obese) and endline data. A Z-score of 0 represents the population mean. A Z-score above 2 indicates obesity (BMI \>2 standard deviations above the mean) in children and teens. A decline in BMI Z-score would be a positive outcome in this weight management study.
