Longitudinal studies evaluating the relationship between UPF consumption and the incidence of Metabolic Syndrome (MetS) and its components are still scarce. This study aimed to evaluate the effect of UPF consumption on the incidence of MetS and its components in adults. A prospective study was conducted with 896 participants from the 1978/79 Ribeirão Preto cohort, São Paulo, Brazil. UPF consumption was evaluated in %kcal and %g at ages 23–25 years. Incidence of MetS and its components were estimated at ages 37–39 years, according to the Joint Interim Statement criteria. Poisson regression was used to assess associations, and interactions with sex were investigated. UPF consumption had no association with MetS (%kcal Adjusted PR: 1.00; 95% CI: 0.99–1.01; %g Adjusted PR: 1.00; 95% CI: 0.99–1.01). However, women with higher UPF consumption, in %kcal and %g, had a higher risk of abdominal obesity (%kcal: p = 0.030; %g: p = 0.003); and women with higher UPF consumption, in %g, had a higher risk of low HDL-cholesterol (p = 0.041). For the other components of MetS, no significant associations were observed in either sex. These findings suggest evidence of no association between UPF consumption and MetS; however, consumption of UPF was associated with increased WC and low HDL-c, but only in women.

“…This number corresponded to 98% of live births that occurred in the eight maternity hospitals in Ribeirão Preto between 1 June 1978 and 31 May 1979. Of these respondents, 2094 were excluded because they were not residents in the city at the time of delivery [ 23 ]. A total of 6973 newborns remained in the study; of these, 6827 were single fetuses, and 146 were twins.…”

“…Finally, 2103 participants were reassessed. Forty twins were excluded, leaving 2063 individuals [ 23 ]. For this study, 29 participants were also excluded because they had no data on the food frequency questionnaire (FFQ), 141 because they did not undergo the bronchoprovocation test, 20 that presented forced expiratory volume in the first second (FEV1) ≤ 65% and 16 because they reported energy intake outside the mean ± 3 standard deviations, considered implausible [ 24 ], totaling 1857 individuals in the final sample ( Figure 1 ).…”

“…After the analysis of the theoretical model by applying the backdoor criterion, the variables suggested for the minimum adjustment set were sex (male and female), age (23,24, and 25 years), household income (<5, 5-9.9, >9.9 minimum wages, no information), smoking (yes and no), the level of physical activity (high, moderate, and low), and alcohol consumption. Since the analysis of the FFQ already considered alcohol consumption, it was not used as an adjustment variable.…”

Background: Ultra-processed Food (UPF) consumption can play a role in the pathogenesis and progression of asthma. The aim of this study was to evaluate the association between the consumption of UPF and asthma. Methods: This cross-sectional study included 1857 adults aged 23–25 years from the Ribeirão Preto-SP birth cohort (1978/1979). The exposure variable was the consumption of UPF (expressed as their percentage contribution to energy intake—% total caloric value [%TCV] and their percentage contribution to the amount of food ingested—%grams), which was assessed with a food frequency questionnaire. Asthma was the outcome and was defined based on a positive methacholine challenge test and the presence of wheezing, chest tightness, or shortness of breath over the last 12 months. Poisson regression with robust variance was used to estimate the association between these variables. Unadjusted analyses and analyses adjusted for sex, age, household income, smoking, and physical activity level were performed. Results: The prevalence of asthma in the sample was 13.2%. The mean total consumption of UPF was 37.9 ± 11.2% TCV (corresponding to 35.1 ± 15.1% grams). There was no association between the consumption of UPF and asthma in adults. Conclusion: This study provides no evidence for an association between the consumption of UPF and asthma in young adults.
