OBJECTIVES: To examine the separate and combined effects of having health insurance and a usual source of care (USC) on access to healthcare for low-income children and to determine if one or the other is superior in ensuring better access to necessary services. METHODS: We conducted cross-sectional, multivariable analyses of data from a mail-return survey of Oregon food stamp program. Results from 2681 completed surveys were weighted back to a population of 84,087 families with adjustments for oversampling techniques and nonresponse. RESULTS: Among low-income Oregon children, those with health insurance and a USC reported the best access to healthcare. In multivariable comparisons to this reference group, insured children without a USC had higher rates of unmet medical need [odds ratio (OR) = 2.18; 95% confidence interval (CI): 1.27-3.73]; no doctor visits in 12 months (OR = 6.77; 95% CI: 3.80-12.06); and problems obtaining specialty care (OR = 4.12; 95% CI: 1.59-10.68). Similarly, having a USC but not health insurance was associated with an even higher likelihood of unmet medical needs (OR = 4.33; 95% CI: 2.85-6.57); as well as unmet prescription needs (OR = 2.64, 95% CI: 1.77-3.94), and problems obtaining dental care (OR = 4.83; 95% CI: 3.31-7.06). CONCLUSIONS: Incremental policy solutions are being proposed that focus on either health insurance coverage for children or expanded access to primary care. However, neither approach displaces the need for the other. The effects of a USC and health insurance, together, are additive predictors of the likelihood that children have optimal access to necessary healthcare services.
