Regression Discontinuity Estimates

	(1)	(2)	(3)
	BMI screened annually (2004–2007)	BMI screened biennially (2008–2015)	Full study period (2004–2015)
Panel A: Overweight reports
BMI z-score	−0.007	0.002	−0.005
	(0.008)	(0.011)	(0.007)
Bandwidth	2.702	3.046	2.704
N	42,863	37,932	76,578
Panel B: Obese reports
BMI z-score	−0.013	−0.016	−0.016*
	(0.009)	(0.012)	(0.008)
Bandwidth	0.976	1.114	0.918
N	26,756	24,943	46,749

Note: Robust standard errors are clustered by school. Choice of optimal bandwidth follows Calonico et al.¹⁵ Long-run effect indicates the effect of BMI report at kindergarten on BMI z-score at fourth grade. All estimations contain controls for age, gender, race, and school meal status. ^*p < 0.1, ^**p < 0.05, ^***p < 0.01.
