The mean age among surveyed children less than 3 years of age is 16.0 months. Seventy one (15.3%) of the surveyed children were under the age of six months. Ninety one (19.6%) were between 6 and 11.9 months, one hundred and ninety five (42%) were between 12 and 23.9 months, and one hundred and seven (23.1%) were between 24 and 35.9 months. These figures are slightly different than the baseline survey, due to no children under the age of 6 months being admitted into the baseline study. This was mainly due to the beliefs that is was difficult to obtain a venous blood sample and lack of clear reference values for hemoglobin in young infants2. This changed with the midterm survey though and children under the age of six months were admitted. Due to the change in age requirements the bracket of less than six months of age fluctuates in each of the surveys from 0% to 26.4% to finally 15.3%. All other age brackets are relatively the same as the final percentages given above.
