Resumen

The objective of the present study was to assess the association between the observed and perceived food environment and food insecurity among households with children <18 years in Lima, Peru. This was a cross-sectional study including an income-stratified random sample of households (n 329) in Villa el Salvador, a low-income district in Lima, Peru. Data were collected with a household questionnaire - including the Household Food Insecurity Access Scale (HFIAS) and the University of Pennsylvania's Perceived Nutrition Environment Survey (NEMS-P) - and a neighbourhood food outlet census, including recording of food outlets' GPS coordinates. Three-quarters of the households interviewed were food insecure. Compared with food secure households and adjusting for socio-demographic covariates, food insecure households were more likely to disagree to having easy access (OR 5-4; 95 % CI 2-1, 13-4), high quality (OR 3-1; 95 % CI 1-7, 5-5) and variety (OR 2-5; 95 % CI 1-4, 4-6) of fresh fruits and vegetables in their neighbourhood. About 60 % (513 out of 861) of the food outlets identified in participants' neighbourhoods were classified as fresh, including markets, bodegas, and fruit and vegetable vendors. There was no difference in distance to fresh food outlets by household food insecurity; all households were on average within 52-62 m from a fresh food outlet (~2-min walk). Despite negative perceptions of their neighbourhood food environment, food insecure households had similar physical access to fresh food sources than their food secure counterparts. Thus, changes to the food environment may not alleviate food insecurity in urban poor areas of Peru. Copyright © The Author(s), 2022.
