Health insurance status and healthcare utilization in US adults with cLBP (N = 700).

In the cLBP subgroup frequent healthcare users (≥10 healthcare visits per year) were more likely to be insured, than those who had fewer healthcare visits (p = 0.0008), adjusted odds ratio for age, gender, race, education, number of comorbidities (aOR) 2.10 ([95% Confidence interval] 1.03–4.26), p = 0.04. The distribution of health insurance types was significantly different in frequent healthcare users. Among those cLBP subjects, who reported ≥10 healthcare visits in the past year 50.5% were covered by federal or state-subsidized insurance plans (the “other” category includes other government-sponsored plans) vs 34.6% of those who had less frequent healthcare visits (p = 0.006), aOR 2.10 (1.21–3.64) for Medicare, 2.31 (1.35–3.97) for Medicaid, p = 0.001.
