Consumo de productos ultraprocesados y enfermedades respiratorias sibilantes en niños. Proyecto SENDO

Abstract

Introduction The consumption of ultra-processed products (UP) is associated with many diseases in the adult, such as arterial hypertension, diabetes, or asthma. Objective To determine whether the consumption of UP in children is associated with wheezing respiratory diseases (asthma or bronchitis/recurrent wheezing). Material and methods A cross-sectional study was conducted within the Follow-up of the Child for Optimal Development ?SENDO? project (an open, multidisciplinary and multiple outcome study of Spanish children). The consumption of UP was calculated using semi-quantitative questionnaires on the frequency of food consumption. The foods were grouped according the NOVA classification, and the daily consumption was estimated along with the percentage of kilocalories from the UP. The exposure was grouped into “high” and “low” from the median consumption. Odds ratios and 95% confidence intervals were calculated for wheezing respiratory diseases associated with the high consumption UP, using low consumption as a reference. Crude and multi-adjusted estimators were calculated, and mixed regression models were used to take into account the correlation between siblings. Results In the 513 children studied (51.8% males, mean age 5.2 years), the mean consumption of UP was 446.76 g/day, representing 39.9% of the total calories ingested. A high consumption of UP was associated with an increase of 87% in the prevalence of wheezing respiratory diseases (OR 1.87; 95% CI 1.01-3.45). It was found that a higher consumption of UP multiplied by 2.12 (95% CI 1.10-4.05) the prevalence of bronchitis/recurrent wheezing. Conclusions The results of this study show a direct relationship between UP consumption and the prevalence of wheezing diseases in children.
