Psychological and academic adjustments were assessed in a group of 130 adopted children (six to 12 years of age) living in five different family constellations: only children, children with younger adopted siblings only, children with younger biological siblings only, children with older adopted siblings only, and children with older biological siblings only. Few differences were found from one...

Epidemiologic evidence indicates that several markers of exposure to childhood infections are inversely associated with the risk of childhood leukemia and lymphomas. We used the Swedish Family-Cancer Database to assess the effects of number of siblings on the risk of non-Hodgkin's (n = 7,007) and Hodgkin's lymphomas (n = 3,115), leukemias (n = 7,650), and multiple myeloma (n = 1,492) by histopa...
