Health insurance and access to care for families with young children in California, 2001-2005: differences by immigration status.

Objectives To examine differences and trends in health insurance coverage and access to care for California families by immigration status. Methods Cross-sectional data on 37,236 families with young children <18 years of age from the 2001, 2003 and 2005 California Health Interview Survey are used to assess trends in health insurance and access to care for children and their parents by four immigration dyads: (1) both are Citizens; (2) child is a legal resident/citizen, and parent is legal resident (Documented); (3) child is a citizen, and parent is undocumented (Mixed); and (4) both are Undocumented. Results Before and after adjustment for covariates, only children in Undocumented dyads were less likely than Citizen dyads to have insurance (OR = 0.20, CI: 0.16–0.26) and all three measures of access: physician visits (OR = 0.69, CI: 0.52–0.91), dental visits (OR = 0.47, CI: 0.35–0.63), and a regular source of care (OR = 0.51, CI: 0.37–0.69). Parents in all non-Citizen dyads had poorer access than Citizen dyads across all measures, with the exception of dental visits and a regular source for parents in Documented dyads. Children of all dyads except Citizens were more likely to be insured in 2005 vs. 2001. The largest gain was for undocumented dyad children with 2.77 times higher odds (CI: 1.62–4.75) of being insured in 2005 vs. 2001. All children dyads except Mixed were also more likely to have a physician visit. For parents, there was only a decrease in insurance coverage for Citizen dyads (OR = 0.79, CI: 0.67–0.93) and few changes in access. Conclusions While there were relatively few disparities and some improvements in insurance coverage and access for children in California (except for undocumented children), concomitant changes for parents were not observed. Without attention to the family in health care reforms, disparities may not fully resolve for children and may continue or even increase for parents.
