[영문]Objectives. We examined the health status and patterns of health care use of children in US immigrant families. Methods. Data from the 1999 National Survey of America’s Families were used to create 3 subgroups of immigrant children: US-born children with noncitizen parents, foreign-born children who were naturalized US citizens, and foreign-born children with noncitizen parents. Chi-square and logistic regression analyses were used to examine relationships between immigrant status and health access variables. Subgroup analyses were conducted with low-income families. Results. Foreign-born noncitizen children were 4 times more likely than children from native families to lack health insurance coverage and to have not visited a mental health specialist in the preceding year. They were 40% and 80% more likely to have not visited a doctor or dentist in the previous year and twice as likely to lack a usual source of care. US-born children with noncitizen parents were also at a disadvantage in many of these aspects of care. Conclusions. We found that, overall, children from immigrant families were in worse physical health than children from non-immigrant families and used health care services at a significantly lower frequency.
