Prevalence of asthma-like symptoms with ageing

# metadata.dc.description.abstract[].value
BACKGROUND: Change in the prevalence of asthma-like symptoms in
                populations of ageing adults is likely to be influenced by
                smoking, asthma treatment and atopy. METHODS: The European
                Community Respiratory Health Survey collected information on
                prevalent asthma-like symptoms from representative samples of
                adults aged 20-44 years (29 centres in 13 European countries and
                Australia) at baseline and 10 and 20 years later (n=7844). Net
                changes in symptom prevalence were determined using generalised
                estimating equations (accounting for non-response through
                inverse probability weighting), followed by meta-analysis of
                centre level estimates. FINDINGS: Over 20 years the prevalence
                of 'wheeze' and 'wheeze in the absence of a cold' decreased
                (-2.4%, 95% CI -3.5 to -1.3%; -1.5%, 95% CI -2.4 to -0.6%,
                respectively) but the prevalence of asthma attacks, use of
                asthma medication and hay fever/nasal allergies increased (0.6%,
                95% CI 0.1 to 1.11; 3.6%, 95% CI 3.0 to 4.2; 2.7%, 95% CI 1.7 to
                3.7). Changes were similar in the first 10 years compared with
                the second 10 years, except for hay fever/nasal allergies
                (increase seen in the first 10 years only). Decreases in these
                wheeze-related symptoms were largely seen in the group who gave
                up smoking, and were seen in those who reported hay fever/nasal
                allergies at baseline. INTERPRETATION: European adults born
                between 1946 and 1970 have, over the last 20 years, experienced
                less wheeze, although they were more likely to report asthma
                attacks, use of asthma medication and hay fever. Decrease in
                wheeze is largely attributable to smoking cessation, rather than
                improved treatment of asthma. It may also be influenced by
                reductions in atopy with ageing.
