Abstract

OBJECTIVES: Targeting physical activity (PA) is a mainstay in obesity treatment, but its BMI benefits are poorly quantified. We studied long-term predictive PA-BMI relationships in overweight/obese children presenting to primary care. METHODS: Three-year follow-up of 182 overweight/obese 5- to 10-year-olds recruited from 45 Melbourne general practices. PREDICTOR: 7-day accelerometry (counts per minute, cpm). OUTCOMES: change in BMI z score, BMI category, and clinically significant BMI improvement (z score change ≥0.5). ANALYSIS: Linear and logistic regression. RESULTS: Mean (SD) baseline and 3-year BMI z scores were 1.8 (0.6) and 1.8 (0.7), and mean (SD) activity scores 334 (111) and 284 (10..
