2002 and 2010 percentages for each indicator compared using the Wald statistic for the difference between prevalence estimates in 2002 and 2010.
Anemia, defined as Hb<110 g/l, not adjusted for altitude.
ID defined as serum ferritin <12 ng/ml.
IDA defined as low Hb (<110 g/l) with low serum ferritin (<12 ng/ml).
