  1. Notes: MNP refers to micronutrient powder; odds ratios were reported; standard errors in parentheses. The results of control variables are not reported here. Adjusted logistic regression (after control variables) used the following for reference: High adherence = 1, Low adherence = 0. Proper usage = 1, Improper usage = 0
  2. a Village-based delivery channel: MNP was distributed at the village health office, village activity room, or village committee location; township-based: MNP was distributed at the township health center; home visit-based: MNP was distributed to the household in a home visit
  3. b Proper usage (Yes) refers to following the MNP feeding instructions: Adding MNP to warm boiling water and stirring into paste; or mixing MNP with other supplementary food. Proper usage (No) refers to other usage
  4. c High adherence: ≥4 MNP sachets were consumed every week, low adherence: < 4 MNP sachets were consumed every week
  5. *p < .05. **p < .01. ***p < .001
