[quote=Anonymous][quote=jsteele][quote=Anonymous][quote=jsteele][quote=Anonymous][quote=jsteele][quote=Anonymous][quote=jsteele][quote=Anonymous][quote=jsteele]Just to be clear, you prefer to see poor children in DC suffer from asthma and increased risk of diabetes and cancer rather than be provided with an affordable means of reducing those risks? How many children are you willing to see suffer simply because you don't like Charles Allen?[/quote]

Tell me you don’t know how to read studies without telling me…

Jeff, this is embarrassing you fell for that.[/quote]

Here is an analysis of 41 separate studies that concludes, "in children, gas cooking increases the risk of asthma".

That doesn't seem particularly hard to understand.

But, if you are not concerned about the risk, don't replace your stove. Nobody is forcing you. This bill just provides an opportunity for low income folks who do want to replace gas stoves.

The authors aren't very confident about gas cooking being causal. It may only be linked to another variable, like urban living, where gas is readily available.

[quote]
Our finding of an association between gas cooking and asthma in the absence of an association between measured NO2 and asthma suggests that gas cooking may act as a surrogate for causal variables other than air pollutants produced by gas combustion
[/quote][/quote]

You are misinterpreting that quote, which doesn't say anything about urban living. The quote is saying that there may be factors involved with gas cooking beyond the production of NO2 which contribute to asthma and then goes on to say:

"This is supported by an Australian study, where the association between gas cooking and respiratory symptoms remained significant after adjustment for measured NO2."

In other words, NO2 production is not the only problem arising from gas cooking.

DP here. I think you misunderstood what the study says. [/quote]

Why don't you explain it then because I think I understood it perfectly well.
[/quote]

The OP of the quoted section, the authors said asthma doesn't seem to be causal with gas stoves. They believe it is possible gas stoves to represent some other variable that they can't correct for or measure. So, you can't use this study to blame gas stoves for asthma. However, indoor NO2 and wheezing are correlated and the main source of indoor NO2 is gas stoves.[/quote]

You are still misreading. Here is the conclusion:

[quote][b]Conclusions[/b] This meta-analysis provides quantitative evidence that, in children, gas cooking increases the risk of asthma and indoor NO2 increases the risk of current wheeze.[/quote]

If your reading were correct, they could not arrive at this conclusion.

That's the one-liner that people are going to run as headlines. The discussion makes it clear that they don't have a mechanism that would directly implicate gas stoves as a cause for asthma in children. Gas cooking is an indicator of increased risk of asthma, but the reasons for it aren't clear. Gas cooking may be a proxy for some other environmental hazard related to asthma. I believe the main problem is that they don't have indoor PM2.5 readings, the suspected mechanism in gas cooking. Indoor NO2 was easier to link to wheezing because the occurence of wheezing was linked to measured indoor NO2 concentrations, and the only significant indoor source is gas cooking.[/quote]
