Cognitive and neuropsychological functioning in transnationally adopted juvenile delinquents.

AIM: To evaluate cognitive and neuropsychological abilities of adopted delinquent adolescents in institutional care. METHODS: Transnationally adopted adolescents admitted to institutional care (n = 20) and non-delinquent controls who were also transnationally adopted (n = 21) were compared concerning the Wechsler Intelligence Scale for Children and Adults (WISC and WAIS), the Wisconsin Card Sorting Test (WCST) and the Tower of London test (TOL). The adoptive parents answered questions about the adoption, early childhood and family circumstances by a questionnaire sent by mail. RESULTS: The adopted delinquents had a significantly lower IQ and significantly lower results on several other measurements in the WISC/WAIS compared to the controls even after adjustment for age of arrival in the adoptive home. Both groups of adoptees scored low in the WISC/WAIS subscale of arithmetics when compared to the population mean. The TOL test showed that the delinquents were slower and made more errors than the controls. CONCLUSION: The delinquent adoptees scored significantly lower on many variables in the WISC/WAIS. Both delinquent and non-delinquent adoptees had some difficulties with arithmetic. The weak performances in arithmetics might point to some weaknesses in the neuropsychological domain. These results probably have complex explanatory causes and need to be further evaluated.

Influence of perinatal factors on the onset of puberty in boys and girls: implications for interpretation of link with risk of long term diseases.

The authors examined the hypothesis that perinatal factors influence the onset of puberty. Children born as singletons in Uppsala, Sweden, in 1973-1977 were followed for height development before and during their school years (through 16 years of age). In all, 62 children born after preeclampsia, 129 born prematurely, 90 born small for gestational age, 175 born large for gestational age, 49 born short for gestational age, and 38 born tall for gestational age were compared with 688 "normal" children. Differences in age and height at puberty onset and age at menarche were analyzed using the t test and analyses of covariance. For boys, the mean age at puberty onset did not differ between normal boys and those with perinatal factors. Boys born small or short for gestational age were 4 cm shorter than normal boys, and those born large for gestational age were 3 cm taller than normal boys. Among girls, patterns for differences in height were similar. Girls born small for gestational age were 5 months younger than normal girls at the onset of puberty and menarche. Patterns of early childhood growth seemed to explain the relations between these perinatal factors and height and age at puberty. The authors conclude that body size at birth affects stature at puberty; in girls, smallness for gestational age is associated with earlier puberty. Associations between intrauterine exposures and disease risk may be confounded by, or mediated through, effects on adolescence.

Serum lipoproteins and apolipoproteins in children during the first five years of diabetes.

Serum lipoproteins and apolipoproteins were followed in 34 children during a period of 5 years from the onset of diabetes. The group did not differ in these respects from a healthy control group after 5 years of disease. The variation in serum triglycerides and very-low-density lipoprotein (VLDL) triglycerides was more pronounced, some patients having high values. Serum triglycerides and VLDL lipids were significantly correlated to subcutaneous fat, measured as triceps and subscapular skinfolds. None of the patients had albuminuria, so lipid levels could not be related to renal albumin excretion. There was no significant correlation between any serum lipid and haemoglobin A1c.
