  1. Time trends in respiratory symptoms in childhood over a 24 year period.

    Article - En anglais

    Two cross sectional surveys, 24 years apart, using the same respiratory questionnaire, were carried out to examine changes in prevalence rates of cough, phlegm, and wheeze and to relate changes in wheeze to objective peak expiratory flow rates (PEFRs).

    The surveys were done in towns in southern and northern England and South Wales in schoolchildren aged 6.0-7.5 years; n=1655 in 1966 and n=2323 in 1990.

    Parents reported on winter cough and winter phlegm (early morning or day/night) and wheeze; PEFRs were also measured.

    The proportion of children reported as wheezing on most days or nights increased from 3.9% to 6.1% (95% confidence interval (CI) for increase -0.2 to 4.6), with a smaller increase in the prevalence of those who had ever wheezed.
