Aim(s) or purpose: To determine if compliance with a components of a nutrition education program correlate with improvements in BMI z-score among obese adolescents ages 11-18 years enrolled in a multidisciplinary lifestyle modification program.
Design and method: Compliance data was analysed from a multidisciplinary lifestyle modification program for obese (BMI > 95th percentile) adolescents ages 11-18 years at Virginia Commonwealth University in Richmond, Virginia. During the initial six months of the program, adolescents were expected to participate in 3 supervised exercise sessions per week, biweekly behaviour support sessions, and biweekly nutrition education sessions. Parents were invited to attend nutrition sessions with their child during which a registered dietician covered a standard series of lectures. Subjects were expected to maintain and bring a complete food diary to each nutrition session. BMI and BMI z-scores were determined using standardized measurements at baseline and at 6 months. Compliance was monitored by the program coordinator.
Results: Complete data was available for 58 subjects (25 males, 32 females, mean age 13 ± 1.6 years), After 6 months of program participation, mean BMI (36.8 ± 6.5 vs 36.0 ± 6.9 kg/m2) and BMI z-scores (2.4 ± 0.3 and 2.3 ± 0.4SD) both decreased significantly (p Conclusions: Intensive lifestyle modification is associated with modest improvement in mean BMI among obese adolescents, but there are wide variations. After controlling for other baseline and compliance factors, parental participation was a strong independent predictor of changes in BMI Z-score. Parental involvement is an important component of a successful adolescent weight management program.
