	RF	GW-RF
	%IncMSE	Min	Max	Mean	Std
Obesity	175.60	2.33	179.98	79.75	33.94
Physical inactivity	178.85	6.76	115.92	56.95	24.29
Access to exercise	86.85	− 13.01	46.37	14.35	11.68
Food environment index	81.24	− 3.96	55.06	21.94	10.22
Poverty	116.09	− 7.31	64.90	21.85	13.59
Education	143.86	6.34	84.48	37.03	13.09
MSE	1.87	0.75	2.79	1.69	0.48
R2	0.69	0.184	0.780	0.508	0.005

Both models were trained with 5 years of mean data (2013–2017) of 3108 counties.

%IncMSE: mean increase in MSE, MSE: mean squared error.
