Parental smoking and post-infancy wheezing in children: A prospective cohort study
The contribution of parental smoking to wheezing in children was studied in a subset of all British births between April 5 and 11, 1970 (N = 9,670). Children of smoking mothers had an 18.0 per cent cumulative incidence of post-infancy wheezing through 10 years of age, compared with 16.2 per cent among children of nonsmoking mothers (risk ratio 1.11, 95% CI: 1.02, 1.21). This difference was confined to wheezing attributed to wheezy bronchitis, of …
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 consta…
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…
Analysis of completed reproductive histories: A cautionary tale
Recent authors have suggested that cross-sectional studies of adverse outcome of pregnancy are misleading, and that the only valid method of analysis controls for eventual number of pregnancies. The present study shows, by simple examples, that such a method produces results that cannot be interpreted in the way claimed for them
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 signi…
Accuracy of registered causes of neonatal deaths in 1958
The ensuing analyses have been compiled for two main reasons. First, from an epidemiological stand point it is important to know how meaningful are the statistics published by the Registrar General. Secondly, before the Ninth Revision of the Inter national Classification of Diseases is finalized it might be of advantage to ascertain the shortcomings of the Seventh and Eighth Revisions. To this end it is proposed to carry out two studies. The firs…
