title: [Respiratory symptoms in school-age children, in 7 areas of France].
abstract: A study of respiratory symptoms in 6918 schoolchildren aged 6-10 years was carried out in 1975, in 7 French areas having different pollution levels. The proportion of children with respiratory symptoms (cough and/or wheezing), dyspnoea, colds and colds "going to the chest" was higher in Paris than in the other areas. The frequency was related to age, allergy and some socio-economic factors. After adjustment for these factors the difference in the respiratory symptoms between those in Paris and elsewhere was still statistically significant. According to 1974 average pollution data, air was more polluted in Paris than in the other areas, particularly for black smoke.
