Longitudinal study of respiratory conditions among schoolchildren in Israel: interim report of an epidemiological monitoring program in the vicinity of a new coal-fired power plant.
Second and fifth grade schoolchildren living within 19 km of a 1400 megawatt coal-fired power plant were followed-up. The children were first studied in 1980, before the power plant went into operation, and in 1983 after two units were operating. They performed pulmonary function tests (PFT), and their parents filled out American Thoracic Society-National Heart and Lung Institute health questionnaires. In the younger cohort, respiratory symptoms and pneumonia and measles were more common in 1983 than in 1980, while in the older cohort pneumonia and measles showed higher prevalence in 1983 but most respiratory symptoms became less common. Temporal changes in prevalence of respiratory symptoms and diseases and annual increases in PFT within three communities in the region with different expected levels of pollution were analyzed. It appears that effects of age, epidemics, and background variables rather than environmental pollution are responsible for the observed differences.
