Table 3. Multiple linear regression analyses with SB or PA as the dependent variable.
| Independent variables | SB (min/day) | LPA (min/day) | MVPA (min/day) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| B | β | P | B | β | P | B | β | P | |
| Model 1 | |||||||||
| Age at independent walking (mos.) | 10.88 | 0.13 | 0.001 | -6.35 | -0.10 | 0.022 | -4.54 | -0.17 | <0.001 |

Model 1: Adjusted for gender, months of age, interaction (gender × months of age), schools, and accelerometer wear time.
Model 2: As Model 1 plus birth weight and current weight.
B, unstandardized regression coefficient; β, standardized regression coefficient.
SB, sedentary behavior; LPA, light physical activity; MVPA, moderate-to-vigorous physical activity.
