ABSTRACT Objective: To determine if there is an association between the altitude of the living place and chronic malnutrition (CM) and obesity in Peruvian children less than five years old. Materials and methods: This is a secondary analysis of the National Monitoring of Nutritional Indicators Survey (2007-2010). CM was defined as a <2 SD height/age ratio; obesity was defined as a >2 SD weight/height ratio, and poverty was defined as the presence of one or more unsatisfied basic needs. The cutoff value was established at 2500 meters above sea level. Results: Nearly 4000 children (3845) were included. Below 2500 meters altitude, CM was more frequent in children more than 24 months old (13.3%), as well as in poor children (20.5%). Obesity was more frequent in children less than 24 months old (11.1%), as well as in those who were not poor (8.5%). At =2500 m altitude, CD was more prevalent in children more than 24 months old (32.5%), as well as in poor children (35.8%). Obesity was more frequent in children 24 months old or less (5.8%), as well as in poor children (4.5%). Living in cities below 2500 m altitude (odds ratio (OR): 0.31; 95% confidence interval (CI): 0.23-0.44), being 24 months old or less (OR: 0.61; 95% CI: 0.49-0.77) and not being poor (OR: 0.31; 95% CI: 0.23-0.41) were protection factors for not developing CM. Living in cities <2500 m altitude (OR: 2.67; 95% CI: 1.70-4.19) and being 24 months old or less (OR: 2.03; 95% CI: 1.35-3.06) increased the likelihood for being obese. Conclusion: There may be an association between high altitude and malnutrition. Chronic malnutrition is usually found in high altitude populations, and obesity is usually found in low altitude populations
