Hi Nathalie, It's funny, we are just analysing data from RDC were we are looking into that.... First preliminary analysis and litterature review make us think Oedema & MUAC would be more adapted (but MUAC might also overestimate a little bit). I will let you know when we completed all the analyis. There is also an interesting article published this year on this subject: "Growth pattern from birth to adulthood in African pygmies of known age" Fernando V. Ramirez Rozzi, Yves Koudou, Alain Froment, Yves Le Bouc & Jeremie Botton. http://www.nature.com/ncomms/2015/150728/ncomms8672/full/ncomms8672.html I hope this help, Pascale

super thanks. keep me informed! one more question: if you want to select 6-59months, which height do you take?...
