Early childhood television viewing predicts explosive leg strength and waist circumference by middle childhood

Table 2 Unstandardized beta coefficients reporting the association between televiewing at 29 months and an increase in televiewing between 29 and 53 months and fitness indicators in middle childhood

	Model 1		Model 2
Independent variables	Standing long jump (Grade 2)		Waistline (Grade 4)
1. Early televiewing (hours per week)	-.361 ^c	[−.576, -.145]	.009	[−.005, .073]
2. Increase in televiewing (hours per week)	-.285 ^b	[−.436, -.134]	.047^a	[.001, .094]
Adjusted R square	.101		.441

Note. The regression for Model 1 is adjusted for child sex, family income, weight for gestational age, overeating and weekly participation in physical activity at 29 months, and age in months and weight status (coded as 0 = normal weight and 1 = overweight) in the second grade. The regression for Model 2 controls for maternal BMI, immigration status, and level of education, and child age in months and weight status in the second grade.
^a = p < .05., ^b = p < .01. ^c = p < .001.
