Resumo

ObjectiveTo investigate the association between neighbourhood food availability and the consumption of ready-to-consume products (RCP), either processed or ultra-processed, and unprocessed/minimally processed foods (UF-MPF) by children.DesignCross-sectional. 24 h Dietary recalls were collected from children from January 2010 to June 2011. Neighbourhood food availability data were collected from 672 food stores located within 500 m of participants' homes, using an adapted and validated instrument. Neighbourhood-level socio-economic status (SES) was obtained by calculating the mean years of household head's education level in each census tract covered by 500 m buffers. Foods that were consumed by children and/or available in the food stores were classified based on their degree of industrial processing. Multilevel random-effect models examined the association between neighbourhood food availability and children's diets.SettingSantos, Brazil.SubjectsChildren (n 513) under 10 years old (292 aged <6 years, 221 aged 6 years).ResultsThe availability of RCP in food stores was associated with increased RCP consumption (P<0001) and decreased UF-MPF consumption (P<0001). The consumption of UF-MPF was positively associated with neighbourhood-level SES (P<001), but not with the availability of UF-MPF in the neighbourhood.ConclusionsResults suggest that food policies and interventions that aim to reduce RCP consumption in Santos and similar settings should focus on reducing the availability in food stores. The results also suggest that interventions should not only increase the availability of UF-MPF in lower-SES neighbourhoods, but should strive to make UF-MPF accessible within these environments.
