Linear regression analyses on consequences of screen-time change (hr/d) from age 11 to 15 years—1993 Pelotas (Brazil) Birth Cohort Study (N = 4,118)
| Outcome | Unadjusted | Model 1a | Model 2b |
|---|---|---|---|
| Beta (95% CI) | Beta (95% CI) | Beta (95% CI) | |
| BMI (kg/m2) | .02 (−.02, .05) | .06 (.02, .10) | .06 (.01, .10) |
| Sum of skinfolds (mm) | .001 (−.1, .1) | .09 (−.05, .22) | .2 (.1, .3) |
| Waist circumference (cm) | .1 (.01, .2) | .2 (.1, .3) | .1 (.04, .2) |
| Leisure-time PA (min/wk) | 8 (4, 11) | 11 (7, 16) | 8 (3, 11) |
| Systolic BP (mm Hg) | .04 (−.04, .13) | .16 (.06, .26) | .04 (−.06, .14) |
| Diastolic BP (mm Hg) | −.04 (−.09, .01) | −.04 (−.10, .02) | .04 (−.02, .11) |
BP = blood pressure.
a
Model 1: Adjusted for screen time (min/d) at baseline.
b
Model 2: Adjusted for model 1 plus sex, skin color, assets index, and maternal schooling.
