Significant Predictors for 10-year Change in Percent Body Fat Separately in White and Black Girls Between Ages 9-10 (Visit 1) and Ages 18-19 (Visit 10).

Response variables Significant explanatory variables	?	SE(ß)	Partial R-square	P
Percent of body fat increase for White girls (n=162)

Regression model by stepwise selection from explanatory variables: age, BMI, Insulin and maturation stage at baseline, parents' obesity level, change in Insulin Z score over 10 year follow-up, percent of calories from protein, from fat, from carbohydrate, from saturated fat (mean of interviews) during 10 year follow-up, and interaction terms (nutrients* baseline Insulin, nutrients* change in Insulin Z score).
