Objectives-To investigate the relation between traffic indicators in the area of residence and the occurrence of chronic respiratory disorders in children.
Methods-A population based survey was conducted in 10 areas of northern and central Italy (autumn 1994 to winter 1995) in two age groups (6-7 and 13-14 years).
Information on several respiratory disorders and on traffic near residences was collected with a questionnaire given to children and to their parents.
The sample analysed included 39275 subjects (response rate 94.4%). Outcomes were : (a) early (first 2 years of life) respiratory diseases, and (b) current respiratory disorders (asthma, wheeze, cough, or phlegm in the past year).
Odds ratios (ORs) and 95% confidence intervals (95% CIs), adjusted for several potential confounders, were estimated from logistic regression models.
Main results were stratified by level of urbanisation (metropolitan areas, other centres).
In the metropolitan areas, high frequency of lorry traffic in the street of residence was associated with significantly increased risks for many adverse respiratory outcomes.
Among early respiratory diseases, the strongest associations were found for recurrent bronchitis (OR 1.69,95% CI 1.24 to 2.30), bronchiolitis (1.74,1.09 to 2.77) and pneumonia (1.84,1.27 to 2.65), although no association was detected for episodes of wheezing bronchitis. (...)
