Objective: To analyse the association between food consumption according to the degree of processing and incidence of hypertension in CUME project participants. Design: Longitudinal study in which food consumption was evaluated according to the percentage contribution of daily energetic intake (%/d) of each NOVA classification group (unprocessed/minimally processed foods and culinary preparations (U/MPF&CP); processed foods and ultra-processed foods (UPF)). Hypertension was defined according to American College of Cardiology/American Heart Association (ACC/AHA) criteria. Adjusted relative risks (RR) and their 95% confidence intervals (95 % CI) were estimated by Poisson regression models with robust variances. Setting: Brazil. Participants: 1221 graduates classified as non-hypertensive at baseline and monitored for 2 years. Results: Daily energetic percentage from each group according to degree of processing was 64·3 (sd 12) % for U/MPF&CP; 9·9 (sd 5·8) % for processed foods and 25·8 (sd 11) % for UPF. Incidence of hypertension was high (152/1000 person-years; n 113, 193/1000 person-years in males and n 257, 138/1000 person-years in females). After adjusting for potential confounders, participants in the upper quintile of daily energetic intake of U/MPF&CP presented a reduced risk of hypertension (RR: 0·72; 95 % CI 0·52, 0·98), while those in the upper quintile of daily energetic intake of UPF presented an increased risk of the outcome (RR: 1·35; 95 % CI 1·01, 1·81). Conclusions: In this prospective cohort of Brazilian middle-aged adult university graduates, the highest consumptions of U/MPF&CP and UPF were associated with, respectively, reduced and increased risk of hypertension. Additional longitudinal studies are needed to confirm our results.
RESUMOO objetivo deste estudo foi analisar a validade dos diagnósticos autodeclarados de síndrome metabólica (SM) e de seus componentes pelos participantes da Coorte de Universidades Mineiras (CUME). Uma subamostra de 172 participantes da coorte (33 homens e 139 mulheres, idade 38 ± 11 anos) foi aleatoriamente selecionada para este estudo. A presença de SM foi definida segundo os critérios da International Diabetes Federation (IDF). Dados de peso, altura, pressão arterial, concentração sérica de glicose, triglicerídeos e HDL-c foram autodeclarados em questionário online da coorte e as mesmas variáveis foram aferidas presencialmente mediante protocolo padronizado em laboratórios das instituições de ensino superior envolvidas no projeto. Os dados autodeclarados e aferidos foram comparados por meio de coeficiente de correlação intraclasse (CCI), coeficiente Kappa (k) e diferenças entre medidas autodeclaradas e aferidas segundo a metodologia de Bland e Altman. As prevalências da SM foram de 4,7%e 5,2%, de acordo com os dados autodeclarados e aferidos, respectivamente. O coeficiente Kappa entre diagnósticos de SM autodeclarado e aferido foi 0,814, indicando concordância quase perfeita, situação similar à observada para a obesidade (k=0,882). Os demais componentes da SM apresentaram concordâncias moderadas (k=0,41 a 0,60). Os CCIs também indicaram excelente concordância para peso, estatura, IMC e HDL-c, respectivamente, 0,989, 0,995, 0,983 e 0,761. A glicose apresentou baixa concordância (CCI: 0,336). Concluiu-se que participantes do projeto CUME forneceram informações válidas para os diagnósticos autodeclarados de SM e de seus componentes.

The study concludes that the CUME project participants provided valid information for the self-reported diagnoses of MetS and its components. ABSTR ACT The aim of this study was to analyze the validity of self-reported diagnoses of metabolic syndrome (MetS) and its components through participants of the Cohort of Universities of Minas Gerais (CUME). A subsample of 172 cohort participants (33 males and 139 females, age 38 ± 11 years) was randomly selected for this study. The presence of MetS was defined according to the criteria of the International Diabetes Federation (IDF
Background: The Food Frequency Questionnaire (FFQ) is usually used in epidemiological studies to assess food consumption. However, the FFQ must have good accuracy, requiring its validation and reproducibility for the target population. Thus, this study aimed to describe the construction of the online Food Frequency Questionnaire (oFFQ) used at the Cohort of Universities of Minas Gerais (CUME project, Brazil) and evaluate its validity and reproducibility.Methods: The oFFQ was answered two times in 1 year (March/August 2018—March/April 2019; n = 108 participants—reproducibility), and four 24-h dietary recalls (24hRs) were applied in two seasons of the southern hemisphere [two 24hRs in autumn (March/June 2018) and two 24hRs in winter (August/September 2018); n = 146 participants—validity]. To assess the validity and reproducibility, the intraclass correlation coefficients (ICCs) were estimated.Results: The oFFQ had 144 food items separated into eight groups (dairy products; meat and fish; cereals and legumes; fruits; vegetables; fats and oils; drinks; other foods). In assessing the validity, ICCs for energy and macronutrients were considered moderate, ranging from 0.41 (energy) to 0.59 (protein), while the ICCs for micronutrients were considered low to moderate, ranging from 0.25 (fibers) to 0.65 (vitamin B6). Regarding reproducibility assessment, ICCs for energy and all the assessed items were considered moderate to excellent, ranging from 0.60 (vegetables) to 0.91 (vitamin E and retinol).Conclusions: The self-reported oFFQ had satisfactory validity and reproducibility. So, it can be used to analyze the association between food consumption and chronic diseases in the participants of the Cohort of Universities of Minas Gerais (CUME project—Brazil).
Objective: To verify the association between heavy episodic alcohol consumption [binge drinking (BD)] and overweight in 2,909 adults from the Cohort of Universities of Minas Gerais (CUME Project) baseline, Brazil. Method: Cross-sectional study in which sociodemographic, anthropometric (BMI ≥ 25 kg/m2 = overweight) and dietary intake data were collected. This study evaluated the occurrence and monthly frequency of BD (≥ 4 drinks at one time for women; ≥ 5 drinks at one time for men, in the last 30 days). Results: The prevalence of BD and overweight were 41.3% and 40.8%, respectively. BD increased the prevalence of overweight by 19%, and, BD exposure by ≥ 5 days / month increased it by 31%. Conclusion: BD on a single or multiple occasion during the month was associated with a higher prevalence of overweight. Therefore, such a lifestyle should be considered in weight gain prevention strategies.
