do gas stoves cause asthma

Introduction

The potential link between gas stove use and asthma has been a topic of significant research interest. This synthesis aims to present the key findings from multiple studies to determine whether gas stoves contribute to the development or exacerbation of asthma.

Key Insights

Increased Risk of Childhood Asthma:
- Gas stove use is associated with an increased risk of current asthma among children, with an estimated 12.7% of childhood asthma cases in the US attributable to gas stove use .
- Children exposed to gas stoves have higher odds of asthma, wheeze, and bronchitis, especially when ventilation is not used.
Respiratory Symptoms in Adults:
- Among adults with asthma, gas stove use did not show a significant impact on pulmonary function or respiratory symptoms.
- However, other studies suggest that indoor sources of combustion, including gas stoves, are associated with increased asthma morbidity in adults.
Gender Differences:
- Women who use gas stoves for cooking have an increased risk of asthma-like symptoms, including wheeze and shortness of breath, compared to men .
Role of Ventilation:
- Using ventilation when operating gas stoves is associated with lower odds of asthma, wheeze, and bronchitis in children, and better lung function.
Nitrogen Dioxide and Other Pollutants:
- Gas stoves emit nitrogen dioxide and other respiratory irritants, which are linked to increased respiratory symptoms in children .
- The presence of nitrogen dioxide from gas stoves is a marginal risk factor for respiratory symptoms, suggesting additional risks beyond nitrogen dioxide exposure.

Conclusion

The collective evidence indicates that gas stove use is associated with an increased risk of asthma and respiratory symptoms, particularly in children and women. The use of ventilation can mitigate some of these risks. While the impact on adults with asthma is less clear, the overall findings suggest that reducing exposure to gas stove emissions could benefit respiratory health, especially in vulnerable populations.

Using ventilation when operating gas stoves in homes is associated with higher lung function and lower odds of asthma, wheeze, and bronchitis in children aged 2-16 years.

Association of respiratory symptoms and lung function in young adults with use of domestic gas appliances

Gas cooking is significantly associated with respiratory symptoms in women, but not in men, possibly due to greater exposure due to cooking more frequently.

Domestic gas appliances and lung disease

In East Anglia, the use of gas cooking is significantly associated with respiratory symptoms in women, but not in men.

Respiratory symptoms in children and indoor exposure to nitrogen dioxide and gas stoves.

Gas stove exposure is a significant risk factor for respiratory symptoms in children, with nitrogen dioxide exposure being a marginal risk factor.

Health risks from indoor gas appliances.

Gas appliances contribute to asthma and carbon monoxide poisoning, and simple behavioral changes can reduce exposure.

Indoor combustion and asthma.

Exposure to indoor combustion, particularly coal stoves, is associated with asthma development and severity in children.

Association between gas stove use and childhood asthma in the Canadian CHILD Cohort Study

Gas stove use is associated with an increased risk of childhood asthma in Canada, but the Canadian CHILD Cohort Study found no significant association between gas stove use and asthma in Canadian children.
