^dResults from all matched surveys. For example, HFIAS was collected at 18, 24, 30, and 36 months but since the starting median age at the time of first survey was 34 months, the number of matched surveys were 207 forms from 89 children. For anthropometry, there were 40 children under 24 months of age who had 2–3 repeat measures, while there were 76 children 24 months or older with 10–13 repeat measures
