A questionnaire survey of all health districts in England and Wales was carried out at the end of 1984 to document screening programmes for identifying hearing loss in childhood. The response rate was 81.3%. All districts performed distraction testing, all but nine aiming at doing so at 7-9 months of age. All districts tested children''s hearing at school, generally before 7 years of age. The number of times that children were screened both before school and at school varied considerably, from one to six times before school and one to six times at school. Few districts collected information that would allow them to make judgments about the efficiency of effectiveness of their screening programmes.  相似文献

This paper investigates the association between obesity and skill attainment in early childhood (aged 2-3 years). Data from the German Socio-Economic Panel Study are used to estimate models of developmental functioning in four critical areas (verbal skills, activities of daily living, motor skills, and social skills) as a function of various measures of weight (including body mass index and obesity) controlling for a rich set of child, parent, and family characteristics. The findings indicate that, among boys, obesity is associated with reduced verbal skills, social skills, motor skills, and activities of daily living. Among girls, obesity is associated with reduced verbal skills. Further investigations show that the correlations exist even for those preschool children who spend no time in day care, which implies that the correlations cannot be due solely to discrimination by teachers, classmates, or day care providers.  相似文献
