Recent WASH research

There have been some interesting studies published so far in June
There are links to the abstracts or full text of the studies below on Sanitation Updates :

Re: Recent WASH research

Thanks for posting this.
Lets see if that figure of minimum of 60% sanitation coverage for effects to start being measurable (see neighbourhood sanitation study) holds up to further investigation. It could also be combined with the identified population density to OD relation of the study further below. While the latter just confirms what has been a common assumption for long, it still gives some interesting harder data to work with.

Re: Recent WASH research

Dear Dan,
Thanks for repeating the post from Sanitation Updates on "Recent WASH research" here on the Forum. Would you be ably to make the post a bit more focused though, i.e. is this research on health aspects primarily? Or research on anything WASH-related? If it is on health, then I would prefer to move it to the health category of the forum.

I actually get a bit overwhelmed if you put 10 new articles into one post... Probably each of them would warrant a discussion thread on their own where we could get in touch with the authors...
Thank you, Kris, for picking out certain aspects that you find most important; both of them are indeed intriguing. Which of the articles spoke about 60% sanitation coverage as a minimum to see effects? That last one on population density is an interesting one. The comparison on health outcomes for urban people was new to me:

Studies on child health in developing countries often find that children are healthier in urban areas than in rural areas. There are many reasons for this disparity. People in urban areas tend to be richer and better educated. Further, more densely populated places are more likely to have easier access to health services that matter for child survival and development, such as trained doctors, maternal care, and medicines.

www.niussp.org/article/population-densit...t-sante-des-enfants/

Hmmm, "richer and better educated" if you live in an urban slum? Might be a bit of an over-generalisation.

Regards,
Elisabeth

The 'Exposure–response relationship of neighbourhood sanitation and children’s diarrhea' one if I remember correctly. It is a bit hidden as a factor of '0.6' probably because the authors themselves are not so sure about it.

Regarding the urban/rural devide: I think this is an artifact of how effects are measured. If you just look at early childhood deaths then urban areas often look better as easily accessed medical services (even if expensive) often do prevent deaths there.

Re: Recent WASH research

Hi Elisabeth

I appreciate the suggestion and will just post a single key study in the future rather than a list.
