Regression Discontinuity Estimates: First-Time Reports and Long-Run Effects

	First-time reports			Long-run effect
	(1)	(2)	(3)	(4)
	BMI screened annually (2004–2007)	BMI screened biennially (2008–2015)	Full study period (2004–2015)	Full study period (2004–2015)
Panel A: Overweight reports
BMI z-score	−0.015	0.007	−0.012	−0.026
	(0.011)	(0.015)	(0.010)	(0.030)
Bandwidth	2.975	3.281	2.859	4.576
N	23,984	23,835	43,852	11,775
Panel B: Obese reports
BMI z-score	−0.001	−0.018	−0.006	−0.022
	(0.011)	(0.016)	(0.011)	(0.032)
Bandwidth	1.209	1.339	1.046	2.100
N	16,850	16,683	27,437	6719

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.
