Can Meals Outside Homes Impact Sodium Intake?

Abstract

ABSTRACTBackgroundThe WHO currently recommends a daily sodium intake of 2 g and has established the goal of a 30% reduction in mean salt intake by 2025.ObjectiveWe sought to estimate sodium intake in study participants according to the locations of where they consumed meals and their demographic and socioeconomic characteristics and practices related to salt consumption.MethodsA population-based, cross-sectional study was conducted with a sample of 2574 individuals aged ≥10 y who answered the 2015 Campinas-Brazil Nutrition Survey. Mean sodium intake was estimated using a 24-h recall log and associations with the independent variables were tested using generalized regression analysis stratified by age group.ResultsSodium intake was higher in male participants as well as adolescents and adults who reported eating ≥1 meal outside the home (6.07% and 7.06% increase, respectively). Per meal, sodium was consumed more outside the home at breakfast, during an afternoon snack, and at dinner among adolescents. No significant differences were found in the analysis by type of meal among the adults and seniors.ConclusionsSodium intake exceeded the WHO recommendation in all age groups analyzed. Having ≥1 meal outside the home was associated with greater sodium intake among adolescents and adults. Measures to regulate the food industry and dietary/nutritional education strategies targeting consumers are important to reducing the sodium intake of the population.
