BACKGROUND

Despite expansions in public health insurance programs, millions of US children lack coverage. Nearly two-thirds of Oregon's uninsured children seem to be eligible for public insurance.

OBJECTIVES

We sought to identify uninsured but eligible children and to examine how parental coverage affects children's insurance status.

METHODS

We collected primary data from families enrolled in Oregon's food stamp program, which has similar eligibility requirements to public health insurance in Oregon. In this cross-sectional, multivariable analysis, results from 2861 surveys were weighted back to a population of 84,087 with nonresponse adjustment. Key predictor variables were parental insurance status and type of insurance; the outcome variable was children's insurance status.

RESULTS

Nearly 11% of children, presumed eligible for public insurance, were uninsured. Uninsurance among children was associated with being Hispanic, having an employed parent, and higher household earnings (133-185% of the federal poverty level). Children with an uninsured parent were more likely to be uninsured, compared with those who had insured parents (adjusted odds ratio 14.21, 95% confidence interval 9.23-20.34). More surprisingly, there was a higher rate of uninsured children among privately-insured parents, compared with parents covered by public insurance (adjusted odds ratio 4.39, 95% confidence interval 2.00-9.66).

CONCLUSIONS

Low-income Oregon parents at the higher end of the public insurance income threshold and those with private insurance were having the most difficulty keeping their children insured. These findings suggest that when parents succeed in pulling themselves out of poverty and gaining employment with private health insurance coverage, children may be getting left behind.
