  1. NB At baseline, the prevalence of anemia, underweight, stunting, and wasting was zero
  2. * p < 0.05; ** p < 0.001 using Fisher’s exact test
  3. a Hemoglobin: ≥ 11 Gram/deciliter, b: 10 to 10.9 Gram/deciliter, c: 7 to 9.9 Gram/deciliter, d: < 7 Gram/deciliter
  4. e Normal underweight, stunting, or wasting: ≥ −2 SD of the WHO median for WAZ, LAZ, or WLZ
  5. f Moderate underweight, stunting, or wasting: ≥ −3 SD but < −2 SD of the WHO median for WAZ, LAZ, or WLZ
  6. g Severe underweight, stunting, or wasting: < −3 SD of the WHO median for WAZ, LAZ, or WLZ
