Risk and protective factors for Long COVID in Brazilian adults (CUME Study).

Background: Most people recover from COVID-19, however, between 5 to 20% have experienced new, recurring, or continuous health problems four or more weeks after being infected, a phenomenon called Long COVID, and whose reasons for its manifestation are incipient. Our objective was to analyse the risk and protective factors for Long COVID in Brazilian adults participating in the CUME Study. Methods: The CUME Study is a prospective cohort conducted with graduates from federal universities in the State of Minas Gerais, Brazil. In this study, 390 participants who answered the baseline questionnaire in 2016 and the third follow-up questionnaire in 2022 (which contained a block of questions about occurrence of COVID-19 and Long COVID) were included. The diagnosis of Long COVID was based on self-reporting of persistence of signs and symptoms of COVID-19 between 30 days and 6 months after remission of the disease. To estimate the risk and protective factors for Long COVID, a hierarchical multivariate statistical analysis was conducted using the Poisson regression technique. Results: Long COVID was observed in 48.9% of the participants. The following characteristics were identified as risk factors for the outcome: female sex (RR = 1.56; 95% CI = 1.22-1.99); prior diagnosis of hypertension (RR = 1.46; 95% CI = 1.19-1.80); having contracted COVID-19 in the first (RR =1.38; 95% CI = 1.07-1.79) or in the second waves (RR = 1.33; 95% CI = 1.07-1.65) of the pandemic period; and having presented three or more signs and symptoms during the acute phase of COVID-19 (RR = 2.99; 95% CI = 1.08-8.24). On the other hand, having a doctoral/postdoctoral educational level (RR = 0.69; 95% CI = 0.50-0.94) was identified as a protective factor for the outcome. Conclusion: Health system managers and healthcare professionals should be aware of the socioeconomic profile and disease history of patients who have had COVID-19 because women, people with a prior diagnosis of hypertension, and those who manifested multiple signs and symptoms of COVID-19 during the acute phase of the disease were at greater risk of developing Long COVID.

Fatty acid intake and prevalence of depression among Brazilian graduates and postgraduates (CUME Study).

BACKGROUND: Dietary fatty acids are related to the development of several inflammatory-related diseases, which may include depression. So, the association between fatty acids, culinary oils and fat intake and depression in highly educated Brazilians was evaluated. METHODS: Multicenter cross-sectional study using baseline data from the Cohort of Universities of Minas Gerais. The diagnosis of depression was self-reported, and the daily intake of fatty acids was assessed using a 144-item food frequency questionnaire (FFQ). RESULTS: A total of 7157 participants (68.83 % women) with a median age of 33 years were included. The prevalence of depression was 12.60 % (N = 902). In the adjusted analyses, it was observed that individuals with the highest intake of omega-6 fatty acids (n-6) (OR: 1.36, 95 % CI 1.11-1.67) had a higher prevalence of depression. This increased n-6 intake was identified as a risk factor for depression only among male participants, while among overweight participants, higher n-6 intake was also positively associated with depression. Conversely, a higher ratio of polyunsaturated to monounsaturated and saturated fatty acids (PM/S) was also found to be positively associated with depression, but this association was observed only among non-overweight participants. No associations were found between the consumption of culinary oils or fats and depression. LIMITATIONS: Cross-sectional design limits the assessment of causality. The use of the FFQ can make estimates more difficult. CONCLUSION: Higher consumption of n-6, and higher PM/S ratios were associated with depression, and individual factors can interfere. The mental health care policies should include specific nutritional strategies.

30-Year High Cardiovascular Risk Incidence and its Determinants: CUME Study.

OBJECTIVE: Estimate the incidence of the 30-year high cardiovascular risk and its determinants among graduates of federal universities in Minas Gerais. METHODS: This is a prospective cohort of 2,854 adults aged 20 to 59. The incidence of the outcome was calculated using the Framingham equation and its determinants were determined through multivariate Cox regression. RESULTS: After an average of 2.62 years, the incidence of high cardiovascular risk was 8.09 and 20.1 cases per 1,000 person-years, for females and males respectively. Being male (HR: 2.34; 95% CI: 1.58 - 3.46), employment (HR: 2.13; 95% CI: 1.13 - 3.99), high consumption of processed foods (HR: 2.44; 95% CI: 1.21 - 4.90), and being physically active (HR: 0.63; 95% CI: 0.41 - 0.98) were associated with high cardiovascular risk. CONCLUSIONS: Among highly educated adults, being male, employment, and high consumption of processed foods are predictors of high cardiovascular risk, while being physically active acts as a protective factor.

Are ambulatory blood pressure parameters associated more with central adiposity than with total adiposity? Results of the ELSA-Brasil study.

Background: Worldwide obesity has a high prevalence, as well as carries a high risk of several chronic diseases, including hypertension. Studies of the association between obesity and ambulatory blood pressure (BP) are scarce and most use only body mass index (BMI) as indicator of adiposity. Thus, we aimed to examine for associations between total and central adiposity and ambulatory BP parameters (BP means and variability, nocturnal dipping and morning surge) among participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: This cross-sectional study (2012-2014) used a subsample of participants (n = 812) of ELSA-Brasil who underwent 24-hour ambulatory BP monitoring to assess systolic and diastolic BP (SBP and DBP, respectively) over 24-hour periods and sub-periods. Indicators for total adiposity were BMI and body fat (BF) and, for central adiposity, waist circumference (WC) and waist-to-height ratio (WHR). Associations were tested using crude and adjusted gamma and logistic regression. Results: Overweight (BMI) and abdominal obesity (WC and WHR) associated positively with mean 24-hour (Coef = 2.71, 3.09 and 4.00, respectively), waking (Coef = 2.87, 3.26 and 4.16, respectively), and sleeping (Coef = 2.30, 2.74 and 3.50, respectively) SBP; mean DBP associated with high WHR in these three periods (Coef = 2.00, 2.10 and 1.68, respectively) and with WC in the waking period (Coef = 1.44). Overweight and abdominal obesity (WC and WHR) were positively associated with SBP variability over 24 h (Coef = 0.53, 0.45 and 0.49, respectively) and in sleep (Coef = 0.80, 0.74 and 0.59, respectively), and with DBP variability in 24 h (Coef = 0.64, 0.73 and 0.58, respectively), wakefulness (Coef = 0.50, 0.52 and 0.52, respectively) and sleep (Coef = 0.53, 0.45 and 0.49); excess BF associated positively with DBP variability over 24 h (Coef = 0.43) and in wakefulness (Coef = 0.38). Lastly, high WHR and excess BF were associated with higher odds of extreme dipping (OR = 1.03 for both), while high WC and WHR associated with higher odds of exacerbated diastolic morning surge (OR = 3.18 and 3.66, respectively). Conclusion: Indicators of adiposity were associated with the BP means and variability, nocturnal dipping and morning surge, with more substantial results for indicators of central adiposity that the others.

Higher caffeine consumption is associated with insufficient sleep time in Brazilian adults (CUME study).

We aimed to evaluate the association between caffeine intake and sleep time in Brazilian adults. This cross-sectional study was conducted with 6,356 participants from the Cohort of Universities of Minas Gerais (CUME Study). Data was collected through an online self-report questionnaire. Of the total, 31.9% of the participants had insufficient sleep. Women were found to sleep less than men (64.1 vs. 35.9%; p < 0.001), as well as being more likely to consume higher doses of caffeine (55.2%, p < 0.001). Coffee (35.7%), dark chocolate (25.2%), milk chocolate (15.2%), and diet soda (11.0%) were the foods that more contributed to caffeine intake. Individuals in the highest quartile of caffeine intake (87.0 - 572.0 mg/day) had a 19% higher prevalence of insufficient sleep compared with the lowest quartile (PR: 1.19; 95%CI: 1.08 - 1.31). Future studies are needed to investigate the genetic and hormonal factors involved in the interindividual response in this population.

The 30-year cardiovascular risk trajectories and their independently associated factors in participants of a Brazilian cohort (CUME Study).

We aimed to analyze the different trajectories of 30-year cardiovascular risk (CVR) and its independently associated factors in participants of the CUME Study, a prospective study with alumni from federal universities of Minas Gerais State, Brazil. In this study, 1,286 participants who answered the baseline (2016) and follow-up (2018 and 2020) questionnaires were included. Trajectories of CVR, according to the Framingham score, were identified with the latent class growth modelling technique with the use of the censored normal model. Analysis of the factors independently associated with each of the trajectories was conducted with multinomial logistic regression technique. Three CVR trajectories were identified: Low-Low (68.3%), Medium-Medium (26.2%), and High-High (5.5%). Male sex, living in a stable union, and having moderate and high intakes of ultra-processed foods were positively associated with the Medium-Medium and High-High CVR trajectories. Having non-healthcare professional training and working were positively associated with the Medium-Medium CVR trajectory, whereas being physically active was negatively associated with the High-High CVR trajectory. In conclusion, more than one-third of participants had CVR trajectories in the Medium-Medium and High-High categories. Food consumption and physical activity are modifiable factors that were associated with these trajectories; thus, implementing health promotion measures could help prevent the persistence or worsen of CVR. On the other hand, sociodemographic and labor characteristics are non-modifiable factors that were associated with Medium-Medium and High-High trajectories, which could help identify people who should be monitored with more caution by health services.

Effect of carotenoids on gut health and inflammatory status: A systematic review of in vivo animal studies.

Carotenoids have anti-inflammatory and antioxidant properties, being a potential bioactive compound for gut health. The objective of this systematic review was to investigate the effects of carotenoids on gut microbiota, gut barrier, and inflammation in healthy animals. The systematic search from PubMed, Scopus, and Lilacs databases were performed up to March 2023. The final screening included thirty studies, with different animal models (mice, rats, pigs, chicks, drosophila, fish, and shrimp), and different carotenoid sources (ß-carotene, lycopene, astaxanthin, zeaxanthin, lutein, and fucoxanthin). The results suggested that carotenoids seem to act on gut microbiota by promoting beneficial effects on intestinal bacteria related to both inflammation and SCFA production; increase tight junction proteins expression, important for reducing intestinal permeability; increase the mucins expression, important in protecting against pathogens and toxins; improve morphological parameters important for digestion and absorption of nutrients; and reduce pro-inflammatory and increase anti-inflammatory cytokines. However, different carotenoids had distinct effects on gut health. In addition, there was heterogeneity between studies regarding animal model, duration of intervention, and doses used. This is the first systematic review to address the effects of carotenoids on gut health. Further studies are needed to better understand the effects of carotenoids on gut health.

Acute effect of a beverage containing Brazil and cashew nuts on oxidative stress, lipemia, and blood pressure of women with cardiometabolic risk (Brazilian Nuts Study): a randomized clinical trial.

Nuts are important sources of antioxidants that combat oxidative stress and improve lipid profile as well as vascular function. However, the intake of typical Brazilian nuts and its acute effect on cardiovascular health needs to be better understood. Thus, the present study aimed to evaluate the acute effect of a beverage containing cashew (Anacardium occidentale L.) and Brazil nuts (Bertholletia excelsa H.B.K.) on postprandial oxidative stress, lipemia, and blood pressure of adult women aged 20 to 55 years with cardiometabolic risk. This was an acute, randomized, parallel arm, controlled clinical trial. The participants received either a beverage containing nuts (30 g Brazil nuts + 15 g cashew nuts) or a beverage without nuts with similar macronutrient composition. Oxidative stress markers and lipid profiles were evaluated at fasting and 4 h after beverage consumption. Blood pressure was measured during fasting and after beverage intake (1, 2, 3, and 4 h). In the postprandial state, there was a greater reduction in malondialdehyde levels in the intervention group compared to the control group (-12.3 ± 0.59 vs. -10.7 ± 0.43 µmol/mL; p < 0.05), which was positively correlated with the concentrations of TG (r = 0.399; p < 0.05), VLDL (r = 0.399; p < 0.05), TG/HDL (r = 0.380; p < 0.05), and blood pressure (iAUC SBP r = 0.391; p < 0.05, iAUC DBP r = 0.409; p < 0.05). The remaining oxidative stress markers showed similar postprandial changes between groups. In women with cardiometabolic risk, a beverage containing Brazilian nuts promoted a significant acute reduction on postprandial malondialdehyde levels. The study was registered in the Brazilian Clinical Trials Registry-ReBEC (protocol: RBR-3ntxrm).

Intra-Amniotic Administration of Cashew Nut (Anacardium occidentale L.) Soluble Extract Improved Gut Functionality and Morphology In Vivo (Gallus gallus).

Cashew nuts are rich in dietary fibers, monounsaturated fatty acids, carotenoids, tocopherols, flavonoids, catechins, amino acids, and minerals that offer benefits for health. However, the knowledge of its effect on gut health is lacking. In this way, cashew nut soluble extract (CNSE) was assessed in vivo via intra-amniotic administration in intestinal brush border membrane (BBM) morphology, functionality, and gut microbiota. Four groups were evaluated: (1) no injection (control); (2) H2O injection (control); (3) 10 mg/mL CNSE (1%); and (4) 50 mg/mL CNSE (5%). Results related to CNSE on duodenal morphological parameters showed higher Paneth cell numbers, goblet cell (GC) diameter in crypt and villi, depth crypt, mixed GC per villi, and villi surface area. Further, it decreased GC number and acid and neutral GC. In the gut microbiota, treatment with CNSE showed a lower abundance of Bifidobacterium, Lactobacillus, and E. coli. Further, in intestinal functionality, CNSE upregulated aminopeptidase (AP) gene expression at 5% compared to 1% CNSE. In conclusion, CNSE had beneficial effects on gut health by improving duodenal BBM functionality, as it upregulated AP gene expression, and by modifying morphological parameters ameliorating digestive and absorptive capacity. For intestinal microbiota, higher concentrations of CNSE or long-term intervention may be necessary.

Food consumption by degree of processing is associated with nocturnal dipping and blood pressure variability: The ELSA-Brasil study.

BACKGROUND AND AIMS: Ambulatory blood pressure monitoring (ABPM) allows the assessment of cardiovascular risk markers that cannot be obtained by casual measurements; however, the evidence on the association between food consumption and blood pressure (BP) assessed by ABPM is scarce. We aimed to evaluate the association between food consumption by degree of processing and ambulatory BP. METHODS AND RESULTS: Cross-sectional analysis (2012-2014) of data from a subsample (n = 815) of ELSA-Brasil cohort participants who performed 24-h ABPM was conducted. Systolic (SBP) and diastolic (DBP) BP means and variability during the 24 h and subperiods (sleep and wake), nocturnal dipping, and morning surge were evaluated. Food consumption was classified according to NOVA. Associations were tested by generalized linear models. The consumption of unprocessed, minimally processed foods, and culinary ingredients (U/MPF&CI) was 63.1% of daily caloric intake, 10.8% of processed (PF), and 24.8% of ultraprocessed (UPF). A negative association was found between U/MPF&CI consumption and extreme dipping (T2: odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.55-0.58; T3: OR = 0.55; 95% CI = 0.54-0.57); and between UPF consumption and nondipping (T2: OR = 0.68, 95% CI = 0.55-0.85) and extreme dipping (T2: OR = 0.63, 95% CI = 0.61-0.65; T3: OR = 0.95, 95% CI = 0.91-0.99). There was a positive association between PF consumption and extreme dipping (T2: OR = 1.22, 95% CI = 1.18-1.27; T3: OR = 1.34, 95% CI = 1.29-1.39) and sleep SBP variability (T3: Coef = 0.56, 95% CI = 0.03-1.10). CONCLUSIONS: The high consumption of PF was associated with greater BP variability and extreme dipping, while the U/MPF&CI and UPF consumption were negatively associated with alterations in nocturnal dipping.

Habitual polyphenol intake of foods according to NOVA classification: implications of ultra-processed foods intake (CUME study).

We aimed to evaluate the intake of dietary total polyphenols and their classes according to NOVA classification among adults of a Brazilian cohort study. This is a cross-sectional study, in which food consumption was assessed using an Food Frequency Questionnaire (FFQ) and polyphenol content (total and their classes) was estimated at Phenol-Explorer for each food category and presented as mean and 95% confidence interval. Adjusted linear regression was used to describe the trend of the association between the quintiles of polyphenols intake (dependent variable) and NOVA group of food consumption (independent variable). The higher consumption of fresh/minimally processed foods is accompanied by a higher intake of total polyphenols and all their classes, while the higher consumption of ultra-processed foods represented the lower intake of total polyphenols and their classes. Fresh foods are the greatest sources of polyphenols, and their daily consumption should be encouraged, while ultra-processed foods are deficient in such bioactive compounds.

Ultra-processed food consumption is positively associated with the incidence of depression in Brazilian adults (CUME project).

OBJECTIVE: To evaluate the association between the consumption of ultra-processed food and the incidence of depression in Brazilian adults. METHODS: This longitudinal study included 2572 participants (M = 936 and F = 1636, mean age of 36.1 years) from the Cohort of Universities of Minas Gerais - CUME Project, Brazil. Ultra-processed food (UPF) consumption (in % of daily energy intake, DEI), as defined by the NOVA food classification system, was assessed at baseline using a validated semi-quantitative 144-item food frequency questionnaire. Participants were classified as incident cases of depression if they reported a medical diagnosis of depression in at least one of the follow-up questionnaires. Crude and adjusted cox regression models were used to assess the relationship between UPF consumption and the incidence of depression. RESULTS: After a mean of follow-up of 2,96 years, a total of 246 incident cases of depression were identified. The mean consumption of UPF was 44 g/d or 24 % of DEI. Participants in the highest quartile of UPF consumption (31 to 72 % of DEI) had a higher risk of developing depression (HR = 1.82 95 % CI = 1.15-2.88) than those in the lowest quartile (0 to 16 % of DEI) after adjusting for potential confounders. CONCLUSION: Higher UPF consumption is a risk factor of depression incidence in Brazilian adults with high education level.

Association between total dietary antioxidant capacity and food groups and incidence of depression in a cohort of Brazilian graduates (CUME Project).

This study aims to evaluate the association between Dietary Total Antioxidant Capacity (dTAC) and Total Antioxidant Capacity of food groups (fgTAC) with the incidence of depression in Brazilian graduates participating in the Cohort of Universities of Minas Gerais (CUME Study). The sample consisted of 2572 participants without a medical diagnosis of depression at baseline who responded to at least one follow-up questionnaire from the CUME Project. The Ferric Reducing Antioxidant Power assay was used to determine dTAC. Incidence of depression was estimated by self-reported medical diagnosis of depression during the years of cohort follow-up. Cox regression models were used to relate dTAC and fgTAC to the incidence of depression. The mean follow-up time was 2·96 (1·00) years, and 246 cases of depression were observed (32·3/1000 person-years). The mean dTAC was 11·03 (4·84) mmol/d. We found no associations between higher dTAC and lower risk of developing depression after adjusting for possible confounders. The incidence of depression was inversely associated with fgTAC of the beans and lentils group (hazard ratio (HR): 0·61; 95 % CI 0·41, 0·90). The fgTAC of the junk food group was positively associated with higher incidence of depression after all adjustments (HR: 1·57; 95 % CI 1·08, 2·26). Our findings do not support an association between dTAC and the incidence of depression in a highly educated Brazilian population. However, associations of fgTAC show the importance of analysing the food matrix in which these antioxidants are inserted. We highlight the need for more prospective studies with different nationalities to confirm these results.

Fat Intake and High Triglyceride-Glucose Index in Individuals at Cardiometabolic Risk: An Isocaloric Substitution Analyses.

Insulin resistance (IR) is an important risk factor for cardiovascular diseases, and the triglyceride-glucose index (TyG index) is a potential IR biomarker. Evidence also suggests that fat intake may modulate IR status, but this relationship remains unclear. Thus, the present study aimed to analyze the relationship between the TyG index and isocaloric replacement of macronutrients, including the profile of dietary fatty acids in individuals at cardiometabolic risk.This cross-sectional study enrolled 264 individuals at cardiometabolic risk (age 43.1 ± 16.3 years) who participated in a nutritional intervention study (ReBEC, id: RBR-5n4y2g). The baseline demographic, anthropometric, clinical, dietary, and lifestyle data were used. The TyG index was calculated using the formula ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]. Multivariate nutrient density models were used to analyze isocaloric replacement of fatty acids (as 5% of energy). The chance of having a high TyG index (TyG index >8.83, median value) was decreased by 60% after replacing 5% of the energy intake of polyunsaturated fatty acid (PUFA), saturated fatty acid (SFA), and trans fatty acid (TFA) with monounsaturated fatty acid (MUFA) or PUFA and SFA with protein.Isocaloric replacement of PUFA, SFA, and TFA with MUFA and protein was associated with lower chances of having a high TyG index. These results indicate the importance of macronutrient and dietary fat profiles in the dietary planning of individuals at cardiometabolic risk.

Total Polyphenol Intake, Polyphenol Subtypes, and Prevalence of Hypertension in the CUME Cohort.

Objective:Epidemiological studies have shown associations between polyphenol consumption and reduced risk of cardiovascular diseases. This study aimed to assess the association between polyphenol intake and the prevalence of hypertension.Methods:This cross-sectional study was performed on data from the Cohort of Universities of Minas Gerais (CUME) project. Participants completed an online food frequency questionnaire, and polyphenol intake was assessed using the Phenol-Explorer database and articles. Hypertension was determined by a medical diagnosis, having a blood pressure ≥ 130 mmHg/80 mmHg, or using antihypertensive drugs. Adjusted logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for the prevalence of hypertension.Results:The prevalence of hypertension was 39.57%, and the average intake of total polyphenols was 860.79 mg/day. The highest (5th quintile) intake of flavonoids (mean: 368.46mg/day; OR: 0.83; 95%CI 0.70; 0.97), hydroxybenzoic acids (mean: 379.38mg/day; OR: 0.77; 95%CI: 0.66;0.91), and flavonols (mean: 44.13mg/day; OR: 0.79; 95%CI: 0.67; 0.93) was inversely associated with hypertension prevalence, compared to the lowest intake (1st quintile).Conclusions:Our findings demonstrate that the intake of flavonoids, hydroxybenzoic acids, and flavonols is associated with a lower prevalence of hypertension.

Low polyphenol intake among highly scholarity population: CUME cohort.

In the absence of a recommendation for daily intake of phenolic compounds, to compare the intake of the main dietary polyphenols between populations is a really challenge. This study aimed to estimate the total dietary intake of polyphenols, classes and their food sources among Brazilian graduates and postgraduates. This was a cross-sectional study using baseline data from the Cohort of Universities of Minas Gerais (CUME project). Food consumption was assessed using a quantitative food frequency questionnaire with 144 food items. Polyphenol intake was estimated from the Phenol-Explorer and US Department of Agriculture database, and previous studies that evaluated the phenolic content of specific foods. A total of 4130 individuals of both sexes with a median age of 34 (18-86) years old were finally included. The median intake of total polyphenols adjusted for energy was 753.41 mg/day (interquartile range - IQR=461.80; p<0.001), and the most consumed classes were phenolic acids and flavonoids, with median intakes of 552.30 mg/d (IQR=429.78; p<0.001) and 154.70 mg/day (IQR=108.70; p<0.001), respectively. The main food sources of polyphenols were coffee, peanuts, beans, and fruits. A lower intake of total polyphenols and their classes was observed in a population with similar characteristics to those from developed countries. The results demonstrate the importance of disseminating nutritional information about foods, so that the consumption of natural foods is prioritized. New studies that evaluate the consumption of polyphenols and their impact on human health are recommended to establish a daily recommendation for the consumption of such compounds.

Effects of minimally and ultra-processed foods on blood pressure in Brazilian adults: a two-year follow up of the CUME Project.

AIM: To assess the association of food consumption according to degree of processing with changes in systolic (SBP) and diastolic (DBP) blood pressure in adult participants of a Brazilian cohort. METHODS: Longitudinal study with 2496 adult participants of the Cohort of Universities of Minas Gerais (CUME Project). Food consumption was categorized by food groups according to degree of processing following the NOVA grading system: unprocessed/minimally processed foods/culinary ingredients (U/MPF&CI), processed foods (PFs) and ultra-processed foods (UPFs). unprocessed/minimally processed foods/culinary ingredients (U/MPF&CI), processed foods (PFs) and ultra-processed foods (UPFs). Changes in SBP and DBP were categorized (decreased, maintained, increased). Independent associations between exposure and outcomes were verified using multiple generalized ordered logistic models adjusted for potential confounders. RESULTS: After a two-year follow-up, the consumption of U/MPF&CI (% daily caloric intake) reduced the chance of increasing DBP (P for trend = 0.014), with a more evident effect among participants within the 5th quintile of this food group (odds ratio (OR) = 0.55; 95% confidence interval (CI): 0.34-0.97]. On the other hand, the consumption of UPFs (% daily caloric intake) raised the chance of increasing DBP (P for trend = 0.005) and was more evident among participants within the quintiles of higher consumption (4th quintile - OR = 1.97; 95% CI: 1.25-3.10; 5th quintile - OR = 1.79; 95% CI = 1.12-2.86). No associations were found between food consumption according to degree of processing and changes in SBP. CONCLUSION: Higher consumption of U/MPF&CI and UPFs were independently associated to lower and greater chances of increased DBP in adult participants from CUME Project.

30-Year High Cardiovascular Risk Incidence and its Determinants: CUME Study / Incidencia del alto riesgo cardiovascular de 30 años y sus determinantes: Estudio CUME / Incidência do alto risco cardiovascular de 30 anos e seus determinantes: Estudo CUME

ABSTRACT Objective: Estimate the incidence of the 30-year high cardiovascular risk and its determinants among graduates of federal universities in Minas Gerais. Methods: This is a prospective cohort of 2,854 adults aged 20 to 59. The incidence of the outcome was calculated using the Framingham equation and its determinants were determined through multivariate Cox regression. Results: After an average of 2.62 years, the incidence of high cardiovascular risk was 8.09 and 20.1 cases per 1,000 person-years, for females and males respectively. Being male (HR: 2.34; 95% CI: 1.58 - 3.46), employment (HR: 2.13; 95% CI: 1.13 - 3.99), high consumption of processed foods (HR: 2.44; 95% CI: 1.21 - 4.90), and being physically active (HR: 0.63; 95% CI: 0.41 - 0.98) were associated with high cardiovascular risk. Conclusions: Among highly educated adults, being male, employment, and high consumption of processed foods are predictors of high cardiovascular risk, while being physically active acts as a protective factor.

RESUMEN Objetivo: Estimar la incidencia del alto riesgo cardiovascular de 30 años y sus determinantes en graduados de universidades federales de Minas Gerais. Métodos: Cohorte prospectiva con 2.854 adultos de 20 a 59 años. Se calculó la incidencia del desenlace usando la ecuación de Framingham y sus determinantes a través de la regresión multivariante de Cox. Resultados: Después de un promedio de 2,62 años, la incidencia del alto riesgo cardiovascular fue de 8,09 y 20,1 casos por 1.000 personas-año, respectivamente, en los géneros femenino y masculino. Ser masculino (HR: 2,34; IC95%: 1,58 - 3,46), trabajar (HR: 2,13; IC95%: 1,13 - 3,99), un alto consumo de alimentos procesados (HR: 2,44; IC95%: 1,21 - 4,90) y ser activo físicamente (HR: 0,63; IC95%: 0,41 - 0,98) se asociaron con el alto riesgo cardiovascular. Conclusiones: En adultos con alta educación, ser masculino, trabajar y el alto consumo de alimentos procesados son predictores del alto riesgo cardiovascular, mientras que ser activo físicamente es un factor de protección.

RESUMO Objetivo: Estimar a incidência do alto risco cardiovascular de 30 anos e seus determinantes em egressos de universidades federais mineiras. Métodos: Coorte prospectiva com 2.854 adultos de 20 a 59 anos. Calculou-se a incidência do desfecho pela equação de Framingham e seus determinantes pela regressão de Cox multivariada. Resultados: Após uma média de 2,62 anos, a incidência do alto risco cardiovascular foi de 8,09 e 20,1 casos/1.000 pessoas-ano, respectivamente, nos sexos feminino e masculino. O sexo masculino (HR: 2,34; IC95%: 1,58 - 3,46), trabalhar (HR: 2,13; IC95%: 1,13 - 3,99), elevado consumo de alimentos processados (HR: 2,44; IC95%: 1,21 - 4,90) e ser ativo fisicamente (HR: 0,63; IC95%: 0,41 - 0,98) associaram-se ao alto risco cardiovascular. Conclusões: Em adultos com alta escolaridade, o sexo masculino, trabalhar e o elevado consumo de alimentos processados são preditivos do alto risco cardiovascular, enquanto ser ativo fisicamente é um fator de proteção.
