TABLE 3.
Linear regression models, predicting adolescent growth and development from earlier childhood adiposity. The six factors of BMI and pictogram, at time points before PHV, appear only in models predicting subsequent PHV. Each predictor is in a separate regression model. Model N’s range from 724 (models of adiposity 3yrs before age at PHV) to 4999 (models using adiposity immediately before PHV).

Models predicting PHV adjust for age at PHV.
Models adjust for exact age (to month) when age 10 adiposity (BMI or pictogram) was obtained. These dependent variables were only analyzed with predictor variables BMI and pictogram at age 10yr, as these are the only factors always measured earlier in time; for example, for many girls their BMI immediately before PHV was measured at age 11yr or later, and thus was not prior to growth from age 10 to 18yr.
