| Résumé : | [BDSP. Notice produite par INIST gyR0x0hH. Diffusion soumise à autorisation]. Background Two-thirds of complaints received by the Hong Kong Environmental Protection Department in 1988 were related to poor air quality. In July 1990 legislation was implemented to reduce fuel sulphur levels. The intervention led to a reduction in respiratory symptoms and bronchial hyperresponsiveness of primary school children. The objectives of this study were to investigate the differences in respiratory health between non-smoking women living in the more polluted district (Kwai Tsing) and those living in the less polluted district (Southern) ; to assess the impact of the government air quality intervention ; and to study the effect of environmental tobacco smoke on respiratory health in non-smoking women in both districts. Method A total of 3405 non-smoking women, aged 36.5 years (standard deviation=3.0), from two districts with good and poor air quality respectively before the intervention were followed yearly from 1989 to 1991. Binary latent variable modelling was used to summarize the six respiratory symptoms and to estimate the effects of risk factors. Results In 1989, living in the polluted district was associated with poor respiratory health (odds ratio [OR]=1.55,95% confidence interval [CI] : 1.11-2.17, P<0.01). After the intervention, in the polluted district only, sulphur dioxide levels fell by up to 80% and sulphate concentrations in respirable particulates by 38%. Between 1989 and 1990-1991, there was no significantly greater decline (P>0. (...) |
