BACKGROUND
Models are needed for implementing weight management interventions for adolescents through readily accessible venues. This study evaluated the feasibility and efficacy of a school nurse-delivered intervention in improving diet and activity and reducing BMI among overweight and obese adolescents.
METHODS
Six high schools were randomized to either a 6-session school nurse-delivered counseling intervention utilizing cognitive-behavioral techniques or nurse contact with provision of information. Eighty-four overweight or obese adolescents in grades 9 through 11 completed behavioral and physiological assessments at baseline and 2- and 6-month follow-ups.
RESULTS
At 2 months, intervention participants ate breakfast on more days/week (difference = 1.01 days; 95% CI 0.11, 1.92), and had a lower intake of total sugar (difference = −45.79g; 95% CI −88.34, −3.24) and added sugar (difference = −51.35g; 95% CI −92.45, −10.26) compared to control participants. At 6 months, they were more likely to drink soda ≤ one time/day (OR 4.10: 95% CI 1.19, 16.93) and eat at fast food restaurants ≤ one time/week (OR 4.62: 95% CI 1.10, 23.76) compared to control participants. There were no significant differences in BMI, activity or caloric intake.
CONCLUSION
A brief school nurse-delivered intervention was feasible, acceptable, and improved selected obesogenic behaviors, but not BMI.
