3. Primary Prevention versus Secondary Prevention
Efforts targeting the entire population1
Healthy weight as well as overweight/obese children
Prevention of child obesity
Environmental and programmatic changes
SCT, SEM, MI
Efforts focus on overweight and obese children
Prevent disease progression and development of co-morbidities
More intensive programs2
SCT
Multi-component behavioral interventions that offered medium- (26 to 75 hours) to high-intensity (>75 hours) contact time, were the most effective, and consistently resulted in small to moderate improvements in weight status (mean difference in BMI change: 2.4). However, evidence is more limited for long-term maintenance of this BMI improvement at or beyond 12-months post-treatment. Finally this review found no evidence of adverse effects on growth, eating disorder pathology, or mental health with behavioral interventions in a limited number of reports.

8. Conclusions Summary of results
A total of 549 families with overweight or obese children, 2-12 y, randomized into MEND/CATCH or NEXT STEPS
Low income families, predominately Hispanic and Black
78% retention at 3 months
Significant intervention effects MEND/CATCH relative to NEXT STEPS at 3 months:
BMI z-score for 6- 8 y, and 9-12 y
Waist and waist:height for 9-12 y
Fat mass for 9-12 y
Diastolic blood pressure for 9-12 y
Secondary Prevention Programs can decrease BMI with elementary school children (ages 6-8 and perhaps 9-12)
Effects are greater with greater dose
Combining Primary and Secondary Prevention Efforts is challenging in a large urban setting
