Ultra-processed foods (UPF) have been associated with cardiometabolic outcomes, but the literature has still not reported their association with incidence of dyslipidemias, one of the most important risk factors for the occurrence of cardiovascular diseases. The objective of this study was to verify the association between consumption of UPF and incidence of dyslipidemia in Brazilian civil servants at a 4-year follow-up. The study used data from 5,275 participants at baseline and on the first follow-up visit in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We applied a food frequency questionnaire (FFQ) at baseline and identified UPF from NOVA, classification of foods as to the extent and purpose of processing. The proportion (in weight) of UPF in the total diet was calculated for each participant and categorized in tertiles, corresponding to low (first tertile), medium (second tertile), and high (third tertile) consumption. A mixed-effects logistic model was used to obtain the incidence of dyslipidemia associated with consumption of UPF. Individuals with medium and high consumption of UPF showed increases in the risks of development of isolated hypercholesterolemia by 12% (OR=1.12, CI:1.00-1.27) and 28% (OR=1.28, CI:1.12-1.47), of isolated hypertriglyceridemia by 14% (OR=1.14, CI:1.03-1.26) and 30% (OR=1.30, CI:1.17-1.45), of mixed hyperlipidemia by 21% (OR=1.21, CI:1.05-1.39) and 38% (OR=1.38, CI:1.18-1.62), and of low-HDL by 12% (OR=1.12, CI:1.00-1.24) and 18% (OR=1.18, CI:1.05-1.32), respectively, compared to participants that consumed less UPF. Our findings showed important cardiovascular risk associated with consumption of UPF and a gradient in the consumption´s effect, so these products should be discouraged.
