Using data spanning 1996-2009 from multiple panels of the Survey of Income and Program Participation, this study investigates children's (average age 8.5 years) physical health, dental visits, and doctor contact among low-income children (n = 46,148) in immigrant versus native households. Immigrant households are further distinguished by household citizenship and immigration status. The findings show that children residing in households with non-naturalized citizen parents, particularly those with a nonpermanent resident parent, experience worse health and less access to care even when controlling for important demographic, socioeconomic, and health insurance variables.
