Woodsmoke from cooking fires linked to pneumonia, cognitive impacts (Say goodbye BBQ)

Two new studies led by University of California, Berkeley, researchers spotlight the human health effects of exposure to smoke from open fires and dirty cookstoves, the primary source of cooking and heating for 43 percent, or some 3 billion members, of the world's population. Women and young children in poverty are particularly vulnerable.

In the first study, the researchers found a dramatic one-third reduction in severe pneumonia diagnoses among children in homes with smoke-reducing chimneys on their cookstoves. The second study uncovered a surprising link between prenatal maternal exposure to woodsmoke and poorer performance in markers for IQ among school-aged children.

The findings on pneumonia, the chief cause of death for children five and under, will be published in the journal Lancet on Thursday, Nov. 10, two days before World Pneumonia Day. While previous research has linked exposure to household cooking smoke to respiratory infections, the latest results come from the first-ever randomized controlled trial – the gold standard of scientific experiments – on air pollution.

"This study is critically important because it provides compelling evidence that reducing household woodsmoke exposure is likely a public health intervention that is on a par with vaccinations and nutrition supplements for reducing severe pneumonia, and is worth investing in," said Kirk Smith, professor of global environmental health at UC Berkeley's School of Public Health and principal investigator of the RESPIRE (Randomized Exposure Study of Pollution Indoors and Respiratory Effects) study.

"There is a huge burden of disease and death due to child pneumonia, and there aren't a lot of good interventions out there," added Dr. Arthur Reingold, a UC Berkeley professor of epidemiology and an internationally recognized expert on infectious diseases, who was not part of the RESPIRE trial. "Randomized controlled trials are frequently demanded by funding agencies and decision makers before they are willing to make substantial investments in new technologies or strategies, and this study provides the needed evidence of an intervention that works."

In the RESPIRE study – which includes partners from Guatemala's Universidad Del Valle, the U.S. Centers for Disease Control and Prevention, University of Liverpool, Norway's University of Bergen and the World Health Organization – researchers worked with rural communities in the Western Highlands of Guatemala. Households with a pregnant woman or young infant were randomly assigned to either receive a woodstove with a chimney or to continue cooking with traditional open woodfires.

The researchers found that using chimneys to vent cooking smoke outside homes led to a more striking decrease in cases of severe pneumonia compared with total pneumonia cases, possibly because the reduction in smoke with the chimney stoves was insufficient to significantly reduce all risk.

"The amount of smoke exposure babies were getting from the open woodfire stoves is comparable to having them smoke three to five cigarettes a day," said Smith, whose research in this field began 30 years ago. "The chimney stoves reduced that smoke exposure by half, on average."

In all there were 265 children in the chimney-stove homes and 253 children in the control homes. During the study, the researchers reported 149 children in the chimney-stove homes and 180 in the open-fire homes with physician-diagnosed pneumonia. For severe pneumonia, characterized by low blood oxygenation, there were 72 cases in the chimney-stove group and 101 in the control group.

In the second study, published online Sept. 24 in the journal NeuroToxicology, Smith led the research team that followed up with some of the families in the RESPIRE trial, which officially ended in 2005 when the infants were 18 months old. In 2010, when the children were 6-7 years old, the researchers recruited 39 mother-child pairs for the study.

The results found, for the first time, a link between exposure to woodsmoke – as determined by carbon monoxide levels measured individually – during the third trimester of pregnancy and lower performance on neurodevelopmental tests when the children were ages 6 and 7. Specifically, the researchers found impairments in visuo-spatial perception and integration, visual-motor memory, and fine motor skills.

"I was surprised because woodsmoke was always considered a risk for respiratory health, but not IQ," said study lead author Linda Dix-Cooper, who conducted the study for her master's thesis in UC Berkeley's Global Health and Environment graduate program. "The implications of our findings are highly worrisome. Neurodevelopmental impacts have societal costs, such as impacts on an individual's future lifetime earnings and educational attainment."

Dix-Cooper added that similar cognitive impacts among children have been noted in previous case reports of childhood acute carbon monoxide poisonings and in epidemiological investigations of other prenatal air pollutant exposures in developed countries' urban centers. However, larger studies are needed to confirm the link with pollution from woodsmoke, she said.

The new studies come amid growing worldwide attention to the need for cleaner, more fuel-efficient cookstoves. Just last year, the United Nations Foundation launched the Global Alliance for Clean Cookstoves, an international public-private initiative championed by Secretary of State Hillary Clinton.

In addition to the health consequences of burning wood, charcoal, dung or crop residue for cooking and heating, the alliance noted that use of traditional cookstoves increases pressures on local natural resources, contributes to climate change and puts women in danger when they forage for fuel in conflict zones.

Finding cleaner alternatives to traditional cookstoves has been an area of active research at UC Berkeley and the Lawrence Berkeley National Laboratory (LBNL) for decades. Some current projects are part of the UC Berkeley-based Blum Center for Developing Economies. They include one led by Smith to replace unhealthy coal stoves in rural China through carbon offsets, and another led by Daniel Kammen, Class of 1935 Distinguished Professor of Energy at UC Berkeley, to develop cost-effective methods to disseminate improved cook stoves throughout Tanzania.

"The biggest collection of people working in the area of cookstoves in the world is at UC Berkeley and LBNL," said Kammen, who co-authored a 2001 study linking smoke from cookstoves and health in Kenya that also appeared in The Lancet. "We are the center of this field in the academic community." Kammen just returned to campus from a one-year stint as the first clean-energy czar at the World Bank, one of the biggest sources of funding for cookstove projects and technology

Could it be that people who use fires as their primary cooking source have other disease causing things in common as well.

A blatant attempt to bank bbqs and grills.

The environment is a cult religion for the environweenies. They have a morbid fear that the Earth God is going to smite them for their sins. For the dupes of this religion, repentence and atonement is their lifestyle. For the ringleaders, this is a money grubbing operation as calculating as the Bhagwan Shree Rajneesh riding one his 90 Roll Royces past his barefoot followers.

"A blatant attempt to bank bbqs and grills."

At least non-propane models. More likely target is wood burning fireplaces. They've been after them for years around here in the Pacific Northwest.

Regarding the third world use of open flame cooking. I'm betting it depends more on ventilation and what is used for fuel. In some places they use pretty much anything that burns including animal scat.

Public education needs to end. Every college and university should survive on their own merits.

Not one taxpayer dollar should go into funding education.

If a school wants to sell education services, let them compete fairly like every other business.

Tax subsidies and student loans have distorted the true demand for education to an absurd level.

This is why most college students drop out before graduating and why so many who do obtain a diploma do not work in their field of study.

The “college bubble”.

I'm not that old, I'm only 27 years old. But back in the '80s, I played on "dangerous" monkey bars and I've never broken any of my bones. *knock on wood*

It's hard to believe on how much things have changed just in a couple of decades.

You think that’s bad?

A panel of expert scientists assembled specifically for the purpose has just recently announced that life leads inevitably to death.

Just think about that for a moment.

What it means is that no one lives forever.

Bureaucrats stay employed by extrapolating data like this and then misapplying it.

Folks that cook over wood 365 days/year, every year have a problem...
So, being a good bureaucrat, we’ll “save” those cooking over wood 12 times a year.....

Movie popcorn with coconut oil....gone!
because if you eat it every day for 10 years, it could be a problem....

CARB has been after the BBQ business for a couple years now. This is from Aug. 2009

“Slayton, owner of Jake’s Tex Mex, almost single-handedly (my words, NOT his) backed the San Joaquin Valley Air District down from a new requirement that would have forced any restaurant grilling 800 pounds of meat a week to spend potentially hundreds of thousands of dollars to buy and install new exhaust systems.”

I once had a manager that worked out there. He said he rented a house with some other guys (1970s), and the furnace burned sawdust.

It wasn't until he moved back East that he found out about the downside of sawdust from a Pac Northwest native. Fleas.

The manager said he always wondered about his ankle rash when he was out there.

Folks, this is a real issue. It’s not about the environment or BBQs.

it’s about people who live in third world huts, with a little fire on the center of the room, with a hole in the roof (to let the smoke out. The fuel is whatever can be found, and Mom and the kids live in this smoky environment.

Humanitarian efforts help by providing simple stoves that burn fuel more completely, and heating food more efficiently with less fuel.

Look up “Rocket Stove” for one that can be made with 16 clay bricks.

I love these kinds of studies. One question though.

Are people who are exposed to woodsmoke made less intelligent by it....

Or are less intelligent people more likely to be using wood instead of electricity?

Makes me wonder how I lived so long. Started out with a coal stove on the high plains, then went to wood in the Ozarks. The thing that nearly killed me was Natural Gas when it blew up our camper trailer in 1956. Burnt my mom horribly.

Maybe the Anazazi of the 4-Corners area died off because they were required by their religion to keep open fires in the kivas. the smoke made the person going in and out “ceremonialy clean”.

Maybe the same for the women cooking.

We had wood and coal stoves for heating and cooking until the mid 60’s and then we got LP gas. I hated wood chopping.

My grandmother cooked with a wood fired cook stove until about 1946 and generations of Americans prepared their food that way and many lived to ripe old ages. They also consumed a diet high in fats like lard, used salt in large quantities especially in home canning and were exposed to hazards the nanny state would never allow, yet they survived. If even half the stuff we are now told is deadly to our health were true, I figure the human race would have died out a long time ago.
