Table 4.

Odds ratios for incident “at risk” of overweight (BMI 85^th-95^th percentile), overweight (>95^th percentile), incident percent body fat > 30%, and incident percent body fat > 35% in 8^th grade girls according to change in activity levels from 6^th to 8^th grade^*

	Change in sedentary activity OR (95% CI)	Change in light activity OR (95% CI)
Incident overweight 85^th (cases/total n = 44/655)	1.00096 (0.99705, 1.00489)	1.00067 (0.99590, 1.00547)
Incident overweight 95^th (cases/total n = 31/824)	0.99485 (0.98966, 1.00006)	0.99871 (0.99318, 1.00427)
Incident %BF ≥ 30% (cases/total n = 177/597)	1.00036 (0.99780, 1.00293)	0.99967 (0.99651, 1.00284)
Incident %BF ≥ 35% (cases/total n = 138/615)	0.99893 (0.99628, 1.00160)	0.99862 (0.99533, 1.00193)

OR, odds ratio

CI, confidence interval

Change = 8^th grade value – 6^th grade value.

Logistic mixed models: Incidence = Change in activity + Race + (Field Center + School within Field Center included as random effects).
