Examination of Hospital Inpatient Enquiry data for England and Wales for the years 1962-81 shows that the annual number of discharges with a diagnosis of undescended testicle has risen by a factor of 2.3. Cohort analysis suggests that the cumulative rate to age 15 of discharge for undescended testis has risen from 1.4% for the 1952 birth-cohort to 2.9% for(More)
The constancy of ratings of behaviour made at home and school between the ages of 7--11, 11--16 and 7--16 is examined. There were moderate correlations between ratings at the different ages (0.31--0.48) but the majority of children in the 'deviant' (top 13 per cent) group at one age had moved out of that group by a later follow-up (4, 5 or 9 years later).(More)
This paper examines early adult outcomes of truancy regarding family formation and health-related behaviour, and is based on data collected in the National Child Development Study, which surveyed all people in Great Britain born in the week 3-9 March 1958, at birth, and at ages 7, 11, 16 and 23. Truants compared to non-truants were found to be relatively(More)
Data from the National Child Development Study have been used to examine the relationship between mother's smoking during pregnancy and neonatal mortality, birthweight and the subsequent development of the child to the age of 11. In this paper analyses are reported which extend this work to examine development by the age of 16. After allowing for a wide(More)
All 155 surviving children from a cohort of 200 very low birthweight infants originally studied in 1984-5 were traced. These infants had careful sequential ultrasound examinations in the neonatal period. The children were examined again at entry into school at 5 years of age. The test of motor impairment (TOMI) and the vocabulary subscale of the Wechsler(More)
This paper presents some findings of a study into early adult outcomes of truancy, which was based on the National Child Development Study, a longitudinal survey of all people in Great Britain born in the week 3rd-9th March 1958. It was found that truancy is associated with lower status occupations, less stable career patterns and more unemployment. Among(More)
-The following summary presents the key findings of an evaluation of a 6 month trial of one Integrated Learning System (ILS) in nine U.K. Schools, conducted by the School of Education, Leicester University. The pupils in the target population ranged from 8 to 13 years of age. The evaluation design was based on the comparison of outcome performance in(More)
The housing conditions of children in the National Child Development Study are related both to 16-year school attainment and also to progress through secondary school from 11 to 16. Children in homes which are crowded or lacking amenities, or in council homes at sixteen have relatively low scores on tests of reading and mathematics at the same age. The(More)
Despite its status as the preferred method for routine enantiopurity analysis in pharmaceutical research, supercritical fluid chromatography (SFC) has historically been unsuited for the accurate and precise measurements required for release testing of active pharmaceutical ingredients (APIs) under current good manufacturing processes (cGMPs).
