Association between gas cooking and respiratory disease in children
Insights
Children using gas stoves for cooking experienced more respiratory issues like coughs and bronchitis. This indoor air quality finding was independent of other environmental and social factors, suggesting gas combustion byproducts may be responsible.
Area of Science:
- Environmental Health
- Pediatric Respiratory Medicine
- Epidemiology
Background:
- Indoor air quality is a significant determinant of respiratory health in children.
- Previous studies have suggested links between domestic environments and childhood respiratory illnesses.
- Understanding the impact of specific indoor pollutants is crucial for public health interventions.
Purpose of the Study:
- To investigate the association between domestic cooking fuel and respiratory symptoms in schoolchildren.
- To identify potential indoor environmental risk factors for respiratory disease in a pediatric population.
- To analyze the first year of a longitudinal study on respiratory health in English and Scottish schoolchildren.
Main Methods:
- A cross-sectional analysis of 5758 children aged 6-11 years from 28 randomly selected areas in England and Scotland.
- Data collection included respiratory symptom questionnaires and examination of environmental and socio-economic factors.
- Statistical analysis to assess the impact of gas cooking versus electric cooking on respiratory health outcomes.
Main Results:
- Children from homes using gas for cooking reported higher incidences of cough, bronchitis, and 'colds going to the chest'.
- Girls using gas stoves also showed increased rates of wheezing compared to those using electric stoves.
- The observed 'cooking effect' remained significant after adjusting for multiple confounding variables including age, social class, and outdoor air pollution.
Conclusions:
- Gas cooking is associated with an increased prevalence of respiratory symptoms in children.
- Oxides of nitrogen produced from gas combustion are hypothesized as the causative agents for increased respiratory illness.
- This finding highlights the importance of indoor air quality from domestic appliances in pediatric respiratory health.
Abstract:
A four-year longitudinal study of the prevalence of respiratory symptoms and disease in schoolchildren and related environmental and socio-economic factors is in progress. We report results for the first year of this study (1973). A total of 5758 children aged 6 to 11 years from 28 randomly selected areas of England and Scotland were examined. In an analysis of the effects on health of possible indoor pollutants, boys and girls from homes in which gas was used for cooking were found to have more cough, "colds going to the chest", and bronchitis than children from homes where electricity was used. The girls also had more wheeze if their families used gas for cooking. This "cooking effect" appeared to be independent of the effects of age, social class, latitude, population density, family size, overcrowding, outdoor levels of smoke and sulphur dioxide and types of fuel used for heating. It was concluded that elevated levels of oxides of nitrogen arising from the combustion of gas might be the cause of the increased respiratory illness.
