The influence of family type on children's behaviour and development at five years.

Development and behaviour at five years were assessed in children from a national cohort; comparisons were drawn between those living in one-parent families, in step-parent families and with both natural parents. On average, children from one-parent families scored worst and children from two-parent families best on tests of behaviour, vocabulary and visuomotor co-ordination. The differences remained significant after allowing for associated influences. The behaviour of children from one-parent families and step-parent families was perceived on average as more 'anti-social' than that of children from two-parent families. Children in one-parent families were seen on average as marginally more 'neurotic' than children in two-parent families.

Educational attainment of 10-year-old children with treated and untreated visual defects.

Children with visual defects who took part in a 10-year survey were compared with their peers on measures of intelligence, reading, mathematics and sporting ability. Results are consistent with earlier findings of increased intelligence among children with myopia and slightly reduced intelligence among children with amblyopia. Those with other visual defects had normal intelligence scores. Once intelligence had been taken into account, only children with mild hypermetropia were under-achieving at reading. Those with severe myopia were reading better than expected. None of the children could be shown to be over- or under-achieving at maths, any variation being due to intelligence. The mothers of children with visual defects perceived them to be less able at sport. Comparison of the performances of children with minor visual defects who had and had not been prescribed spectacles did not suggest any disadvantage for those without spectacles, with the possible exception of children with mild hypermetropia. It is concluded that the majority of visual defects do not affect children's learning, and that current indications for prescribing spectacles need to be validated.

Visual acuity in a national sample of 10 year old children.

The prevalence of defects of visual acuity among the 10 year old children in the 1970 birth cohort was 22.1%, but only in one third of these children was the defect more severe than 6/9. Defects were more common among girls. The relation of defects to social class was complex. Comparison with data collected on the children of the 1958 cohort when they were 11 years old suggests that although the prevalence of 6/9 visual acuity has remained constant over the last decade, the prevalence of more severe defects has declined from 12.9% to 7.3%. These findings have a number of implications for the provision of screening programmes and of ophthalmic services for children.

Teenage mothering: child development at five years.

Developmental outcome at 5 yr was compared in 1031 singleton children of teenage mothers and 10,950 singleton children of older mothers in a national longitudinal study. Children born to teenage mothers and living with them through the first 5 yr performed less well than other children in tests of vocabulary and behaviour at 5 yr of age; they were also shorter on average and had a smaller head circumference. These differences remained significant after allowing for certain social and biological factors, whereas a difference on visuomotor coordination did not. Teenage mothering thus appears somewhat disadvantageous to children's development.

Evidence for increasing prevalence of diabetes mellitus in childhood.

The prevalence of diabetes mellitus among the cohort of children in the Child Health and Education Study studied at age 10 was 1.3/1000. Comparison with prevalences found in the two previous British birth cohort studies suggested that the prevalence of diabetes is doubling roughly every decade. The data suggested that childhood diabetics are a socially advantaged group. These findings have important implications and should be taken into account by health service planners if the needs of these children are to be met in the future.

Family type and accidents in preschool children.

Children living in single-parent families or stepfamilies were found to be more likely to suffer accidental injuries in their first five years of life than children living with two natural parents. Frequent household moves, low maternal age, and perceived poor behaviour in the child were all more strongly associated with overall accident rates than family type, and these disadvantages were more common in atypical families. Family type appeared to be the most important influence on hospital admission after accidents. Overall, there was a close similarity in accident rates between children of single-parent families and stepfamilies, and both groups were more at risk than children living with both natural parents.

Breast feeding, eczema, asthma, and hayfever.

The association of breast feeding with rates of atopic illness during the first five years of life was assessed in a national study of 13 135 children studied during the first week and at age 5 years. Eczema was reported more often in children who had been breast fed; this relationship persisted even after allowance was made for social and family factors influencing the likelihood both of breast feeding and of eczema; the other factors most significantly associated with rates of eczema were parental history of eczema or asthma and advantaged family socioeconomic status. A similar, but less pronounced, positive association of breast feeding with reported hayfever became non-significant after adjustment for intervening factors. Rates of reported asthma were not influenced by breast feeding. "Any wheezing" including asthma was reported more often in children who had not been breast fed, but this association disappeared after adjustment for parental asthma and maternal smoking. Breast feeding does not appear to protect against these atopic diseases. The positive association with reported eczema might relate to accuracy of diagnosis or to associated influences not considered in the analysis; alternatively, it might be due to (recent) environmental contaminants crossing in breast milk, causing eczema in the child.

A non-polarized alternative to polarized nearpoint test cards.

Refractive balance at near is feasible with an inexpensive, nonpolarizing device that yields data which compare favorably with polarizing methods. The device described here differs from the Turville system in that it provides a fused central field flanked by right and left peripheries that are seen monocularly. Among the advantages are simplicity, ease of alignment and low cost.

A national study of asthma in childhood.

A history of asthma was obtained in 3.5% of a representative national sample of children aged 11 years. A further 8.8% had a history of wheezy bronchitis. In the 12 months before the interview, 2% had experienced attacks of asthma and a further 2.9% attacks of wheezy bronchitis. Both conditions were significantly more common among boys than girls, and a history of asthma was reported more frequently among children from non-manual than from manual social classes. Children with frequent attacks of wheezing had lower mean relative weights. A history of eczema and hay fever was more frequently discovered in children with reported asthma than in those with wheezy bronchitis, whereas migraine or recurrent headaches, recurrent abdominal pain, and recurrent throat or ear infections were more commonly associated with wheezy bronchitis than with asthma. The modified Rutter home behaviour scale, which reflects the parental view of the child's behaviour, was significantly raised among children with a history of wheezing, but their school behaviour as judged by the Bristol social adjustment guide showed no such difference. In spite of increased absence from school because of illness, no differences were found in educational attainment between children with a history of asthma or wheezy bronchitis and those with neither condition.
