Clinical and laboratory evaluation of new immigrant and refugee children arriving in Greece.

backgroundMigrant children are a population at risk for various health problems. Despite the increased inflow of migrants in Greece, data regarding their health assessment are lacking. This study aims to describe the clinical and certain laboratory characteristics and identify possible associations in a group of new immigrant (I) and refugee (R) children, arriving in Athens, Greece.

methodsA prospective, cross- sectional study was performed in a migrant outpatient clinic of a tertiary Children's hospital. All immigrant and refugee children, examined to obtain a health certificate, within 3 months of their arrival in the country, were enrolled. Clinical and laboratory information was collected in a pre- designed form. We applied multiple logistic regression models to investigate the association between the child's status (immigrant vs refugee) and health indicators controlling for possible confounding effects, mainly of age and area of origin.

resultsFrom 2010 to 2013, a total of 300 children (I/R:138/162) with a mean age of 7.08 (range 1-14) years were included. Overall, 79.3% presented unknown vaccination status, 21.3% dental and 7.3% additional clinical problems. Latent tuberculosis was identified in 2.7%, while anemia, low serum ferritin and eosinophilia were found in 13.7%, 17.3%, and 22.7% of subjects, respectively. 57.7% had protective antibodies to hepatitis B surface antigen (anti-HBs ≥ 10 IU/L) and 30.6% elevated blood lead levels (EBLLs). Immigrants had less likely unknown immunization (OR = 0.25, p < 0.001), but had increased odds of low ferritin (OR = 1.97, p = 0.043), EBLLs (OR = 2.97, p = 0.001) and protective anti-HBs (OR = 1.79, p = 0.03). Age was inversely associated with anemia (OR = 0.0.89, p = 0.017), low ferritin (OR = 0.91, p = 0.027), EBLLs (OR = 0.86, p = 0.001) or positive anti-HBs (OR = 0.92, p = 0.025). Children from Europe or Africa presented decreased probability of EBLLs (OR = 0.31, p = 0.001, and OR = 0.15, p = 0.005, respectively) compared to those from Asia.

conclusionsNew immigrant and refugee children presented distinct clinical problems and certain laboratory abnormalities. Some of these health issues differed according to their migration status, age and geographic area of origin. These findings provide evidence that may assist the optimal approach of this vulnerable population.
