Maternal risk factors included: being of Quechua ethnicity (OR: 2.57; CI: 1.18, 5.61), being illiterate or having some primary education (OR: 3.04; CI: 2.16, 4.29), and the number of household members (OR: 1.18; CI: 1.09, 1.27). Protective factors included the mother having some level of higher education (OR: 0.52; CI: 0.32, 0.82) and adequate dietary diversity (OR: 0.51; CI: 0.37, 0.69). Conclusions: A third of the study population had growth delay, with associated factors including ethnicity, area of residence, maternal education level, history of prematurity, and household size.
