What is your degree of familiarity with the underlying studies (1=low, 5=high)?

Have done considerable degree of research based on personal interest and motivation.

I cite the studies in my outreach to community environmental justice advocates.

In third world countries it is very common of using gas and kerosine stoves, which give out lot of volatile organic compounds, have very devastating effect on health and especially on respiratory organs. Asthma and other illness are very common.

My consulting firm did a review of the Gruenwald study.

Generaly, the methodology of paper of Gruenwald et al. is poor, and theirs conclusion is vague.

Several different study designs have shown the risk for asthma exacerbations in children. Several birth cohorts suggest that gas stoves increase risk of incident asthma.

Because there must be difference in Developing and developed country style.

Prof Kuku Voyi, head of our Section, did a lot of studies on air quality and asthma and most of us are aware of the danger of gas stoves - however we also do relative risk and hazard analysis and are aware that gas stoves are not high on the list as a cause of asthma in South Africa.

I read the recent published review and most of the underlying studies on which it was based.

Gruenwald et al., 2023 provide a correlation between gas cooking stoves and childhood asthma, but do not attribute the cause of childhood asthma to gas stoves. They also ignored confounding factors, such as time of year when data were collected.

I have read both of these studies.

I've never seen these studies before

Not very much people use the gas stoves

multiple studies have shown same results

I reviewed one of the papers.

Consumer-grade natural gas has also shown to contain a significant number of contaminants that may pose a health risk, including well-know carcinogens such as toluene and xylene. Taking that most of the kitchens in the US have poor ventilation, the current assessment of the impacts of gas stoves might go beyond asthma.
