ABSTRACT. Objective. To assess the correlates of unmet need for medical care among migrant children.Design and Setting. A cross-sectional household survey used multistage sampling to identify migrant families in eastern North Carolina.Participants. Three hundred adult caretakers of 1 (per household) randomly selected child <13 years old.Results. Fifty-three percent of the children had an unmet medical need. The most common reasons for unmet medical need were lack of transportation (80%) and lack of knowledge of where to go for care (20%). Unmet medical need was associated inversely with less than very good health (odds ratio Conclusions. Medical-access barriers among migrant children are largely nonfinancial. Preschool-aged migrant children disproportionately experience unmet medical need. Decreasing forgone care among migrant children will likely require a combination of individual, health-system, and labor-policy modifications. Pediatrics 2004;113:e276 -e282.

[1][2][3][4][5][6][7][8] The inability to obtain needed health care is used to indicate unmet needs for care. 9 A small and growing literature describes the prevalence and correlates of unmet need for health care among children. 9 -19 The prevalence of any unmet need for care among US children Ͻ18 years old is 7.3% 9 and varies by the type of care. For example, the proportion of children reported to experience an unmet need for medical care is 1.6%, whereas 5.3% of children are reported to experience unmet need for dental care. 9 Among all children, unmet need for care is consistently associated with poverty and a lack of insurance. 9 -12,14,15,17-19 Adjusted associations with unmet need for care among US children include 1) school age, 2) living in a single-parent household, 3) less than very good health status (including beddays or activity limitation), and 3) lack of a usual source of care. 9 Few studies examine the prevalence and correlates of unmet health needs among children categorized as ethnic/racial minorities. Although these studies reveal trends, several inconsistencies are evident. As compared with white (non-Latino) children, the prevalence of unmet health needs is generally higher among African American and Latino children. 9,20 -24 Moreover, Latino children have increased unadjusted odds of unmet need (odds ratio [OR]: 1.31; P Ͻ .01). 9 After multivariable control, the association between unmet need and ethnic/racial category became insignificant, 21,22,25 exhibited an inverse association, 9 or persisted among Latino females, as compared with males. 21 Similarly, the prevalence of unmet mental health needs is higher among African American, Latino, and Asian/Pacific Isla...
