The General Linear Model is controlled by drinking water, sanitation service, sex, place of residence (rural or urban) and region (coastal, highlands and jungle), rotavirus vaccine, grade of education (no education, elementary, high school and college) and age (6–11, 12–23, 24–35 and 36–59 months).
Drinking water, sanitation service, Fe supplementation, rotavirus vaccination, where 0: No and 1: Yes.
The variable sex corresponds to 0: female and 1: male. Place of residence 0: urban, 1: rural grade of education, 0: no education, 1: primary, 2: secondary and 3: university. Geographic region, 1: Coast, 2: Highlands and 3: Jungle.
Ages in months are categorical variables.
Model 1 = Fe supplementation during 12 months before the survey (sample = 98 321).
Model 2 = Fe supplementation during 7 d prior to the survey (sample = 114 121).
Survey: DHS 2009–2019 (Peru).
