*
Unadjusted results from joinpoint regression.
^
Adjusted results from multinomial logistic regression, with covariates including child's age, parent's age, race/ethnicity of the child, region of residence, parental education, family composition, parental employment, and child's perceived health status.
BOLD P-value (P<0.05) considered statistically significant.
#
Small sample sizes (N<30) for most years, estimates unreliable.
Note: Low Income = <200% FPL (federal poverty level); Middle Income = 200 - <400% FPL. The FPL in 2011 was $22,350.
