Epidemiology of childhood respiratory disease in Israel
Insights
Children living near a coal power plant experienced more respiratory issues, especially if mothers smoked or homes were crowded. Parental history of lung disease also increased risks for children
Area of Science:
- Environmental Health
- Pediatric Pulmonology
- Epidemiology
Background:
- Children's respiratory health can be influenced by environmental factors and family history.
- Coal-fired power plants are potential sources of air pollutants affecting nearby populations.
- Socioeconomic factors and parental habits may play a role in pediatric respiratory outcomes.
Purpose of the Study:
- To investigate the impact of proximity to a coal-fired power plant on children's respiratory health.
- To analyze the influence of socioeconomic background, parental smoking, and family history of pulmonary diseases on respiratory symptoms and lung function in children.
- To assess the specific contributions of mothers' and fathers' health and habits.
Main Methods:
- Longitudinal study of second and fifth graders living within 19 km of a coal power plant.
- Utilized ATS-NHLI health questionnaires for parents and pulmonary function tests (PFTs) including FVC, FEV1, FEV1/FVC, and PEF for children.
- Statistical analysis to determine the effects of environmental, socioeconomic, and familial factors on respiratory health outcomes.
Main Results:
- Children from crowded homes showed higher FEV1/FVC, fewer respiratory diseases, but more respiratory symptoms.
- Maternal smoking was linked to increased bronchitis, slightly higher asthma rates, lower FEV1/FVC, and reduced FEV1 and PEF in children.
- Family history of pulmonary diseases correlated with higher respiratory symptoms and diseases in children, though PFT parameters were unaffected.
Conclusions:
- Living near a coal power plant and factors like maternal smoking and home crowding significantly impact children's respiratory health.
- Maternal influence on children's respiratory symptoms and diseases appears more pronounced than paternal influence.
- While family history increases disease prevalence, specific environmental or lifestyle factors may be more critical for lung function deficits.
Abstract:
Second and fifth grade schoolchildren living within 19 km from a 1400 megawatt coal fired power plant are followed up. Their parents filled out an ATS-NHLI health questionnaire and they performed pulmonary function tests (PFT), which included: FVC, FEV1, FEV1/FVC, and PEF. The effects of socioeconomic background, smoking habits and pulmonary diseases in the families on the distribution of respiratory symptoms, respiratory diseases and PFT of the children were analysed. Higher FEV1/FVC, lower prevalence of respiratory diseases and excess respiratory symptoms were present among children from crowded homes. Mothers' smoking was found to be connected with significantly higher prevalence of bronchitis, non significant higher prevalence of asthma, significant lower FEV1/FVC and a trend of lower FEV1 and PEF among their children. House heating did not effect the prevalence of respiratory symptoms and diseases of the children. Significantly higher prevalence of respiratory symptoms and diseases was found among children, whose families reported about a history of pulmonary diseases, but no reduction of PFT parameters could be found among them. Mothers' contribution to respiratory symptoms and diseases of their children seems to be more significant than that of the children's fathers. Most respiratory symptoms were more common among children with a history of pneumonia in childhood, especially those who had pneumonia recently.
