Background: Anemia and dementia are common diseases among the elderly, but conflicting data are available regarding an association between these two conditions. We analyzed data from the São Paulo Ageing & Health Study to address the relationship between anemia and dementia.Methods: This cross-sectional observational study included participants aged 65 years and older from a deprived area of the borough of Butantan, São Paulo, Brazil. Data about demographics, education, income, and cognitive and daily life function were collected, as well as blood samples. Anemia and dementia were defined according to WHO and DSM-IV criteria, respectively.Results: Of the 2267 subjects meeting the inclusion criteria, 2072 agreed to participate in the study; of whom 1948 had a valid total blood count and were included in the analysis. Anemia was diagnosed in 203 (10.2%) participants and dementia in 99 (5.1%). The frequency of anemia was higher in patients with dementia according to univariate analysis (odds ratio (OR) = 2.00, 95% confidence interval (CI) = 1.17-3.41, p = 0.01), but this association was not present after adjusting for age (OR = 1.33, 95% CI = 0.76-2.33, p = 0.32). Further multivariate adjustment did not change the results.Conclusion: Although anemia and dementia are frequent disorders in older people, we found their relationship to be mediated exclusively by aging in this low-income population from São Paulo.

Thyroid-associated symptoms are very similar to symptoms of the aging process; thus, improved methods for diagnosing overt and subclinical hypothyroidism in elderly people are crucial. Thyrotropin measurement is considered to be the main test for detecting hypothyroidism. Combined evaluations of thyroid stimulating hormone (TSH) and free-thyroxine can detect overt hypothyroidism (high TSH with low free-thyroxine levels) and subclinical hypothyroidism (high TSH with normal free-thyroxine levels). It is difficult to confirm the diagnosis of thyroid diseases based only on symptoms, but presence of symptoms could be an indicator of who should be evaluated for thyroid function. The most important reasons to treat overt hypothyroidism are to relieve symptoms and avoid progression to myxedema. Overt hypothyroidism is classically treated using L-thyroxine; elderly patients require a low initial dose that is increased every 4 to 6 weeks until normalization of TSH levels. After stabilization, TSH levels are monitored yearly. There is no doubt about the indication for treatment of overt hypothyroidism, but indications for treatment of subclinical disease are controversial. Although treatment of subclinical hypothyroidism may result in lipid profile improvement, there is no evidence that this improvement is associated with decreased cardiovascular or all-cause mortality in elderly patients. In patients with a high risk of progression from subclinical to overt disease, close monitoring of thyroid function could be the best option.Keywords: overt hypothyroidism, subclinical hypothyroidism, diagnosis, treatment, elderlyA Letter to the Editor has been received nad published for this article.

Background: Evidence indicates that physical activity reduces stress and promote a myriad of health-enhancing effects through anti-inflammatory mechanisms. However, it is unknown whether these mechanisms interfere in the association between psychosocial job stress and headache disorders., Objective: To test whether physical activity and its interplay with the systemic inflammation biomarkers high-sensitivity C-reactive protein (hs-CRP) and acute phase glycoproteins (GlycA) would mediate the associations between job stress and headache disorders., Methods: We cross-sectionally evaluated the baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) regarding job stress (higher demand and lower control and support subscales), migraine and tension-type headache (ICHD-2 criteria), self-reported leisure-time physical activity, and plasma hs-CRP and GlycA levels. Conditional process analyses with a sequential mediation approach were employed to compute path coefficients and 95 % confidence intervals (CI) around the indirect effects of physical activity and biomarkers on the job stress-headache relationship. Separate models were adjusted for sex, age, and depression and anxiety. Further adjustments added BMI smoking status, and socioeconomic factors., Results: In total, 7,644 people were included in the study. The 1-year prevalence of migraine and tension-type headache were 13.1 % and 49.4 %, respectively. In models adjusted for sex, age, anxiety, and depression, the association between job stress (lower job control) and migraine was mediated by physical activity [effect = -0.039 (95 %CI: -0.074, -0.010)] but not hs-CRP or GlycA. TTH was associated with higher job control and lower job demand, which was mediated by the inverse associations between physical activity and GlycA [Job Control: effect = 0.0005 (95 %CI: 0.0001, 0.0010); Job Demand: effect = 0.0003 (95 %CI: 0.0001, 0.0007]. Only the mediating effect of physical activity in the job stress-migraine link remained after further adjustments including socioeconomic factors, BMI, smoking, and the exclusion of major chronic diseases., Conclusion: In the ELSA-Brasil study, physical activity reversed the link between job stress and migraine independently of systemic inflammation, while the LTPA-mediated downregulation of GlycA was associated with lower job stress-related TTH., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Context: Thyroid-stimulating hormone (TSH) trajectory classification represents a novel approach to defining the adequacy of levothyroxine (LT4) treatment for hypothyroidism over time., Objective: This is a proof of principle study that uses longitudinal clinical data, including thyroid hormone levels from a large prospective study to define classes of TSH trajectories and examine changes in cardiovascular (CV) health markers over the study period., Methods: Growth mixture modeling (GMM), including latent class growth analysis (LCGA), was used to classify LT4-treated individuals participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) based on serial TSH levels. Repeated measure analyses were then utilized to assess within-class changes in blood pressure, lipid levels, hemoglobin A1c, and CV-related medication utilization., Results: From the 621 LT4-treated study participants, the best-fit GMM approach identified 4 TSH trajectory classes, as defined by their relationship to the normal TSH range: (1) high-high normal TSH, (2) normal TSH, (3) normal to low TSH, and (4) low to normal TSH. Notably, the average baseline LT4 dose was lowest in the high-high normal TSH group (77.7 µg, P < .001). There were no significant differences in CV health markers between the classes at baseline. At least 1 significant difference in CV markers occurred in all classes, highlighted by the low to normal class, in which total and high-density lipoprotein cholesterol, triglycerides, and A1c all increased significantly (P = .049, P < .001, P < .001, and P = .001, respectively). Utilization of antihypertensive, antihyperlipidemic, and antidiabetes medications increased in all classes., Conclusion: GMM/LCGA represents a viable approach to define and examine LT4 treatment by TSH trajectory. More comprehensive datasets should allow for more complex trajectory modeling and analysis of clinical outcome differences between trajectory classes., (© The Author(s) 2024.

Objective: To investigate the relationship between mental health symptoms and the migraine-tension-type headache (TTH) spectrum in middle-aged adults from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil study)., Methods: In this cross-sectional analysis (baseline data: 2008-2010), it was evaluated the relationship between each mental health symptom assessed by the Clinical Interview Schedule-Revised (CIS-R) questionnaire and headache subtypes (migraine and TTH) according to international criteria. It was performed binary logistic regression models, with estimated odds ratios (OR) with their respective 95% confidence intervals (CI) adjusted for confounders including migraine attack frequency., Results: Among 13,916 participants, 70.1% reported any major primary headache subtype within the last year. The most common subtype was definite TTH (33.4%), followed by probable migraine (21.0%), definite migraine (8.5%), and probable TTH (7.2%). Our main findings indicated positive associations between anxiety-related symptoms and the migraine-tension type headache (TTH) spectrum with a clear trend toward definite migraine more than tension-type headache. The presence of somatic symptoms presented a high likelihood for the associations with headaches, mainly definite migraine (OR: 7.9, 95% CI: 6.4-9.8), probable migraine (OR: 4.5, 95% CI 3.7-5.4) and probable TTH (OR: 3.0, 95% CI: 2.3-3.8). Other symptoms associated with headache disorders included fatigue, panic, irritability, anxiety symptoms, concentration problems, forgetfulness, depressive symptoms, and worry. The effect of associations remained significant after controlling for headache attack frequency., Conclusion: This study provides evidence of consistent associations between mental health symptoms and primary headache disorders, with a higher burden of anxiety-based symptoms observed in people with migraine than those with TTH., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Objective: The aim of this study was to investigate whether sex, age, race, income, education, and marital status are associated with having a religion in a sample of Brazilian men and women., Methods: Data were obtained from 15,098 participants of the Brazilian Longitudinal Study of Adult Health, a longitudinal study that ultimately aims to investigate long-term outcomes of chronic diseases. The sociodemographic characteristics and data on religion status were self-reported during interviews conducted by trained personnel. All study procedures followed standard and validated protocols., Results: There was a strong association between being a woman and having a religion (adjusted OR=2.12, 95%CI 1.95-2.31) when compared to men. Regarding age, those with 45-54 years were more likely to have a religion (adjusted OR=1.14, 95%CI 1.03-1.27). Blacks and Browns were more religious (adjusted OR=1.31, 95%CI 1.15-1.49, and OR=1.22, 95%CI 1.10-1.34, respectively) compared to Whites. Those with high income and education were less likely to state having a religion (adjusted OR=0.78, 95%CI 0.70-0.87, and adjusted OR=0.50, 95%CI 0.43-0.59, respectively). Those who did not have a stable conjugal union were found to be less religious (adjusted OR=0.82, 95%CI 0.75-0.89). Stratifying the analysis according to income showed that higher education was inversely associated with religion on both strata: lower and higher annual earnings., Conclusion: This study suggests that education is one of the most important socioeconomic characteristics to consider when studying religion. Race, sex, income, and marital status are also important factors; however, there was not a clear association between religion and age.

Background/objectives: The association between dietary acid load (DAL) and chronic kidney disease (CKD) progression remains controversial. Also, there is a gap in the literature on the association between DAL and mortality. In this study, we evaluated the association between NEAP (net endogenous acid production) and PRAL (potential renal acid load) and the risk of events of all-cause mortality and kidney replacement therapy (KRT) in people with CKD., Subjects/methods: We included 442 patients (250 diabetics) from the Progredir Cohort Study, based in São Paulo, Brazil. We estimated NEAP and PRAL from dietary intake. Events of death before KRT and KRT were ascertained after a median follow-up of 5.8 and 5.1 years, respectively. Cox proportional hazards regression, Weibull regression, and competing risk models were performed., Results: Median NEAP and PRAL were 49.5 and 4.8 mEq/d. There were 200 deaths and 75 KRT events. Neither NEAP nor PRAL were associated with mortality or KRT when all participants were analyzed. After stratification for diabetes, both estimates were positively related to the risk of KRT even after adjustment for age, sex, weight status, glomerular filtration rate, serum bicarbonate, and intakes of protein, phosphorus, and energy (HR 1.31; 95% CI 1.07, 1.60 for NEAP, and HR 1.27; 95% CI 1.04, 1.57 for every 10 mEq/d increments). Competing risk analyses confirmed these findings., Conclusions: DAL estimates were associated with the risk of KRT in people with CKD and diabetes but not in non-diabetics. There was no association between all-cause mortality and DAL., (© 2023. The Author(s), under exclusive licence to Springer Nature Limited.)

Context: The presence of thyroid peroxidase antibodies (TPOAbs) may be considered as an indicator of adverse health outcomes., Objective: We aimed to investigate the potential determinants of TPOAb levels and to analyze the association between TPOAb titers and the risk of all- and specific-cause mortality., Methods: Baseline and longitudinal data of 13 187 participants from the ELSA-Brasil Study were analyzed. We investigated the association of TPOAb, detectability, positivity, and persistent positivity with sociodemographic and lifestyle factors using logistic regressions. Cox proportional hazards and Fine-Gray subdistribution hazard regression analyses were used to verify the association of TPOAbs with mortality., Results: The determinants of TPOAb detectability and positivity were younger age, higher body mass index, female sex, and former and current smoking status. Black, mixed, and other self-reported races, intermediate and higher education, and heavy drinking were determinants of detectable and positive TPOAb levels. Female sex, White race, and former smoking were determinants of persistent TPOAb positivity at 2 visits, although only the female sex maintained its association at 3 visits. Moreover, after multivariate adjustment, there were associations between higher levels of TPOAbs and higher risk of cancer-related mortality among men, and TPOAb detectability and mortality by other causes among women., Conclusion: Sociodemographic and lifestyle-related factors were determinants of multiple TPOAb categories. TPOAb levels were associated with mortality risk; however, the low mortality rate in this sample might have compromised this finding. We suggest further studies to explore the clinical importance of detectable TPOAb levels, not only its positivity, as a potential marker of inflammation., (© The Author(s) 2023.

Objective: To assess the influence of two functional scales- Modified Rankin Scale (m-RS) and Modified Katz Index (m-Katz Index) on long-term mortality in a stroke cohort., Material and Methods: Among 760 stroke survivors (median age: 66 (IQR:56-75), 56.4 % women) m-Katz Index and m-RS scales applied at 1 and 6 months after stroke, were investigated in relation to 12-years of all-cause mortality. Kaplan-Meier survival curves were computed, and time-varying covariate Cox regression models were fitted to calculate hazard ratios (HRs) with 95 % confidence intervals (CIs) in all sample and by sex. The prognostic ability of the fitted models was computed for each model by six different measures., Results: After 12 years of follow-up (median survival time: 7.3 years), 311 participants died. Overall survival curves show lower survival rates among those with the highest levels of disability/dependence (all log-rank p-values <0.0001). These findings were confirmed in all regression models for both sexes, particularly in men who had higher levels of dependence on Activities of Daily Living (ADLs) by m-Katz Index and severe disability by m-RS and presented the highest HR of dying (HR: 3.34 (95 %CI: 2.27-4.92) and HR: 4.94 (95 % CI: 3.15-7.75), respectively)., Conclusions: Both the m-Katz Index and the m-RS scale were good predictors of long-term mortality, which is of importance for guiding the functional rehabilitation of stroke patients. Besides, high levels of disability and dependence were implicated with high mortality risks, regardless of sex., Competing Interests: Declaration of Competing Interest ACGG, KASS, GT, APA, ACV, TEG, NGT, ISS, PAL, IMB, ACG: Declare no conflict of interest.

Objective: Expressing the cardiovascular disease (CVD) risk in relation to peers may complement the estimation of absolute CVD risk. We aimed to determine 10-year CVD risk percentiles by sex and age in the Brazilian population and evaluate their association with estimated long-term atherosclerotic CVD (ASCVD) risk., Methods: A cross-sectional analysis of baseline data from the ELSA-Brasil study was conducted in individuals aged 40-74 years without prior ASCVD. Ten-year CVD risk and long-term ASCVD risk were estimated by the WHO risk score and the Multinational Cardiovascular Risk Consortium tool, respectively. Ten-year risk percentiles were determined by ranking the calculated risks within each sex and age group., Results: Ten-year CVD risk versus percentile plots were constructed for each sex and age group using data from 13,364 participants (55% females; median age, 52 [IQR, 46-59] years). Long-term ASCVD risk was calculated in 12,973 (97.1%) participants. Compared to individuals at the <25 th risk percentile, those at the ≥75 th percentile had a greater risk of being in the highest quartile of long-term risk (ORs [95% CIs] 6.57 [5.18-8.30] in females and 11.59 [8.42-15.96] in males) in regression models adjusted for age, race, education, and 10-year CVD risk. In both sexes, the association between risk percentile and long-term risk weakened after age 50. A tool for calculating 10-year CVD risk and the corresponding percentile is available at https://bit.ly/3CzPUi6., Conclusions: We established percentiles of predicted 10-year CVD risk by sex and age in the Brazilian population, which independently reflect the estimated long-term ASCVD risk in younger individuals., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: RDS received honoraria for consulting, speaker activities, and research from Abbott, Ache, Amgen, AstraZeneca, Biolab, EMS, Hypera, Libbs, Esperion, Kowa, Getz Pharma, Novo Nordisk, Novartis, Merck, PTC Therapeutics, Pfizer, and Sanofi.

Objective: We aimed to evaluate the frequency of obstructive sleep apnea (OSA) in patients with thrombotic primary antiphospholipid syndrome (tPAPS), to investigate the performance of screening tools for OSA in this scenario and to compare clinical/laboratorial differences in tPAPS patients with and without OSA., Methods: We consecutively enrolled patients with tPAPS to undergo sleep studies using a portable monitor. OSA was defined as apnea-hypopnea index ≥15 events/h. Frequency of OSA in tPAPS was evaluated and compared with age-, gender-, and BMI-matched controls (1:3 ratio) from the Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Next, we tested the performance of three different screening tools for assessing OSA in patients with tPAPS. Finally, patients with tPAPS were stratified according to OSA status comparing their clinical and laboratory characteristics (including damage burden measured by Damage Index for Antiphospholipid Syndrome [DIAPS] and biomarkers associated with thrombosis) using standard statistical procedures., Results: Fifty-two patients were included for analysis (females: 82.7%; mean age: 48 ± 14 years; body-mass index: 31.1 ± 6.5 Kg/m 2 ; 25% with moderate-severe OSA). When compared to matched controls from ELSA-Brasil (n = 115), there was no significant differences in the frequencies of OSA (tPAPS: 12/42 [28.6%] vs. controls: 35/115 [30.4%], p = 0.821). Among screening tools, NoSAS had the highest area under ROC curve (AUC 0.806, CI 95% 0.672-0.939, p = 0.001), followed by STOP-Bang (AUC 0.772, CI 95% 0.607-0.938, p = 0.004). Patients with comorbid tPAPS and OSA presented higher levels of von Willebrand factor (vWF) (median 38.9 vs. 32.6, p = 0.038) and DIAPS (median 5 vs. 2, p = 0.020), when compared to those without OSA. OSA remained statistically associated with higher DIAPS, even after controlling for age, disease duration and BMI., Conclusion: OSA is common in patients with tPAPS, with rates comparable to a non-referred population. Both NoSAS and STOP-Bang scores seems to be useful for screening OSA in these patients. Patients with tPAPS+OSA had higher damage burden and higher levels of vWF, which might suggest a more severe phenotype of tPAPS in this scenario., Competing Interests: Declaration of Competing Interest All authors declare no competing financial interests., (Copyright © 2023 Elsevier Inc.

There is a lack of consensus about the association between psoriasis (PSO) and carotid intima-media thickness (cIMT) in literature, since previous studies considered dermatologic clinic patients or general population. This study aimed to compare cIMT levels according to PSO in a sample of 10,530 civil servants form the ELSA-Brasil cohort study and analyze its association with the disease. The PSO cases and disease duration were identified by medical diagnosis self-reported at study enrollment. A paired group was identified by propensity score matching among all the participants without PSO. Mean cIMT values were considered for continuous analysis while cIMT above 75th percentile was considered for categorical analysis. Multivariate conditional regression models were used to analyze association between cIMT and PSO diagnosis, by comparing PSO cases against paired controls and overall sample without disease. A total of n = 162 PSO cases were identified (1.54%) and no difference in cIMT values was observed between participants with PSO and overall sample or control group. PSO was not associated with linear increment of cIMT (vs. overall sample: β = 0.003, p = 0.690; vs. matched controls: β = 0.004, p = 0.633) neither with increased chance of having cIMT above 75th percentile (vs. overall sample: OR = 1.06, p = 0.777; vs. matched controls: OR = 1.19, p = 0.432; conditional regression: OR = 1.31, p = 0.254). There was no relationship between disease duration and cIMT (β = 0.000, p = 0.627). Although no significant relationship between mild cases of psoriasis and cIMT was observed among a wide cohort of civil servants, longitudinal investigation about cIMT progression and severity of disease are still needed., (© 2023.

Objectives: Potentially inappropriate medications (PIM), especially those with potential effects on the central nervous system, can increase the risk of cognitive impairment. We investigated the association of the use of PIM and PIM that may impair cognition (PIM-Cog) with cognitive performance among older adults., Methods: In this cross-sectional study with 2,626 participants, PIM and PIM-Cog were defined by the 2019 American Geriatrics Society Beers criteria. We calculated global cognition and memory, verbal fluency, and Trail Making Test B version (TMT-B) z-scores. Linear regression models adjusted for sociodemographic and clinical variables were used to investigate the association between PIM and cognition., Results: 27% and 7% of the sample (mean age = 65.1 ± 4.1 years old, 54% women, and 61% White) used at least one PIM and PIM-cog, respectively. PIM was associated with poor performance in the TMT-B (β = -0.17, 95% Cl = -0.29; -0.05, p = 0.007). PIM-Cog was also associated with poor TMT-B performance (β = -0.08, 95% Cl = -0.15; -0.01, p = 0.025)., Conclusion: The use of PIM and PIM-Cog was associated with poor executive function among older adults. The review of PIM use and the deprescription of these drugs may be an effective way to improve cognitive function., (© 2023.

Even though suicide is a relatively preventable poor outcome, its prediction remains an elusive task. The main goal of this study was to develop machine learning classifiers to identify increased suicide risk in Brazilians with common mental disorders. With the use of clinical and sociodemographic baseline data (n = 4039 adult participants) from a large Brazilian community sample, we developed several models (Elastic Net, Random Forests, Naïve Bayes, and ensemble) for the classification of increased suicide risk among individuals with common mental disorders. 1120 participants (27.7%) presented increased suicide risk. The Random Forests model achieved the best AUC ROC (0.814), followed by Naive Bayes (0.798) and Elastic Net (0.773). Sensitivity varied from 0.922 (Naive Bayes) to 0.630 (Random Forests), while specificity varied from 0.792 (Random Forests) to 0.473 (Naive Bayes). The ensemble model presented an AUC ROC of 0.811, sensitivity of 0.899, and specificity of 0.510. Features representing depression symptoms were the most relevant for the classification of increased suicide risk. Some of our models presented good performance metrics in the classification of increased suicide risk in the investigated sample, which can provide the means to early preventive interventions., Competing Interests: Declaration of Competing Interest ICP is CNPq research fellow and supported by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Brazil and by FIPE (Fundo de Incentivo à Pesquisa e Eventos) from Hospital de Clínicas de Porto Alegre, Brazil.

Purpose: We aimed to perform a cross-sectional evaluation of the association between dietary patterns and carotid intima-media thickness (cIMT), using baseline data from the Brazilian Longitudinal Study of Adult Health., Methods: The participants with measurement of the cIMT were included (n = 9,624). cIMT was evaluated in a continuous way and categorized as < 75th and ≥ 75th and ≤ 0.9 mm and > 0.9 mm. Dietary patterns (DPs) were identified by principal component factor analysis. Linear and logistic regression models were used to evaluate the association between cIMT and DPs., Results: Three DPs were derived. For each unit increase in the convenience DP score, the odds for cIMT ≥ 75th increased by 13% (OR 1.13; 95% CI 1.05: 1.22) and for cIMT > 0.9 mm increased by 14% (OR 1.14; 95% CI 1.07: 1.22) in the fully adjusted model. In contrast, each unit increase in the prudent DP score decreased by 8% the odds of having cIMT ≥ 75th (OR 0.92; 95% CI 0.86: 0.98) and by 11% of cIMT > 0.9 mm (OR 0.89; 95% CI 0.84: 0.95). Furthermore, each increase in the convenience DP score was associated with increase in the cIMT (β 0.01; 95% CI 0.01: 0.02), while each increase in the prudent DP score was associated with decrease in the cIMT (β -0.01; -0.01; -0.01) in linear regression models., Conclusions: Our results demonstrate that those individuals with adherence to the convenience dietary pattern are more likely to have high cIMT, while those with adherence to a prudent dietary pattern have lower odds for this characteristic., (© 2023.

High salt intake has been linked to both obesity and high blood pressure (BP). Part of the variability of BP attributed to salt intake might be BMI-mediated. To investigate whether hypertension would be an effect modifier in the complex network including salt intake, obesity, and BP, we tested the hypothesis that salt intake has direct and BMI-mediated effects on systolic (SBP) and diastolic blood pressure (DBP). Data from 9,028 participants (aged 34-75 years, 53.6% women) were analyzed. A validated formula was used to estimate daily salt intake from the sodium excretion (12 h urine collection). A path model adjusted for covariates was designed in which salt intake has both a direct and a BMI-mediated effect on BP. In normotensives, standardized beta coefficients showed significant direct (Men: 0.058 and 0.052, Women: 0.072 and 0,061, P < 0.05) and BMI-mediated (Men: 0.040 and 0.065, Women: 0.038 and 0.067, P < 0.05) effect of salt intake on the SBP and DBP, respectively. However, in hypertensive individuals, neither the direct (Men: 0.006 and 0.056, Women: 0.048 and 0.017) nor the indirect effect (Men: -0.044 and 0.014, Women: 0.011 and 0.050) of salt intake on the SBP and DBP were significant. These data suggest that cardiovascular risk stratification should consider the complex interaction between salt intake and weight gain, and their effects on BP of normotensive and hypertensive individuals., (© 2022.

Background: Relationship between reperfusion therapy post-acute coronary syndrome (ACS) and mortality in secondary care is not well-known., Objectives: To evaluate the impact of three therapeutic strategies: (1) exclusive medical therapy, (2) percutaneous coronary intervention (PCI) and (3) coronary artery bypass grafting (CABG) on long-term survival of participants in the Strategy of Registry of Acute Coronary Syndrome (ERICO) study., Methods: Survival analyses for all-cause, cardiovascular (CVD) and coronary artery disease (CAD) mortality were performed according to three therapeutic strategies (exclusive medical therapy, PCI or CABG). Cox regression models were used to estimate the hazard ratio (HR) with respective 95% confidence interval (95%CI) from 180 days to four years of follow-up after ACS. Models are presented as crude, age-sex adjusted and further adjusted for previous CAD, ACS subtype, smoking, hypertension, dyslipidemia, left ventricular ejection fraction and according to the number of obstructed (≥ 50%) major coronary arteries., Results: Among 800 participants, the lowest crude survival rates were detected among individuals who underwent CABG (all-cause and CVD). CABG was correlated to CAD (HR: 2.19 [95% CI: 1.05-4.55]). However, this risk lost significance in the full model. PCI was associated to lower probability of fatal events during four-year follow-up: all-cause [multivariate HR: 0.42 (95% CI: 0.26-0.70)], CVD [HR: 0.39 (95% CI: 0.20-0.73)] and CAD [multivariate HR: 0.24 (95% CI: 0.09-0.63)] compared to those submitted to exclusive medical therapy., Conclusion: In the ERICO study, PCI after ACS was associated to better prognosis, particularly CAD survival.

Introduction: We aimed to investigate the association of frailty with persistent and incident common mental disorders (CMD) in older adults during the pandemic., Methods: We included 706 older adults who participated in the onsite wave of the ELSA-Brasil study (2017-2019) and the online COVID-19 assessment (May-July 2020). CMD were assessed in both waves by the Clinical Interview Schedule-Revised. Frailty was defined according to the physical phenotype and Frailty Index in the 2017-2019 wave. Logistic regression was used to investigate the association of frailty with persistent and incident CMD, adjusted for sociodemographics., Results: Frailty according to both definitions were associated with persistent CMD (Frailty Index: OR = 8.61, 95 % CI = 4.08-18.18; physical phenotype: OR = OR = 23.67, 95 % CI = 7.08-79.15), and incident CMD (Frailty Index: OR = 2.79, 95 % CI = 1.15-6.78; physical phenotype OR = 4.37, 95 % CI = 1.31-14.58). The exclusion of exhaustion (that overlaps with psychiatric symptoms) from the frailty constructs did not change the association between frailty and persistent CMD, although the associations with indent CMD were no longer significant., Limitations: Fluctuations in CMD status were not captured between both assessments., Conclusion: Frailty status before the COVID-19 outbreak was associated with higher odds of persistent and incident CMD in older adults during the pandemic first wave. Identifying individuals at higher risk of mental burden can help prioritize resources allocation and management., Competing Interests: Conflict of interest The authors declare no conflict of interests., (Copyright © 2023 Elsevier B.V.

Background: Experimental studies have linked triglyceride-rich lipoproteins (TRLs) to inflammation, but the extent of this phenomenon in vivo has not been completely elucidated., Objective: We investigated the association between TRL subparticles and inflammatory markers (circulating leukocytes, plasma high-sensitivity C-reactive protein [hs-CRP], and GlycA) in the general population., Methods: This was a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). TRLs (number of particles per unit volume) and GlycA were measured by nuclear magnetic resonance spectroscopy. The association between TRLs and inflammatory markers was determined by multiple linear regression models adjusted for demographic data, metabolic conditions, and lifestyle factors. Standardized regression coefficients (beta) with 95% confidence intervals are reported., Results: The study population comprised 4,001 individuals (54% females, age 50 ± 9 years). TRLs, especially medium and large subparticles, were associated with GlycA (beta 0.202 [0.168, 0.235], p<0.001 for total TRLs). There was no association between TRLs and hs-CRP (beta 0.022 [-0.011, 0.056], p = 0.190). Medium, large, and very large TRLs were associated with leukocytes, with stronger connections with neutrophils and lymphocytes than monocytes. When TRL subclasses were analyzed as the proportion of the total pool of TRL particles, medium and large TRLs were positively related to leukocytes and GlycA, whereas smaller particles were inversely associated., Conclusions: There are different patterns of association between TRL subparticles and inflammatory markers. The findings support the hypothesis that TRLs (especially medium and larger subparticles) may induce a low-grade inflammatory environment that involves leukocyte activation and is captured by GlycA, but not hs-CRP., (Copyright © 2023.

Purpose: The EAT-Lancet Commission released a reference sustainable diet to improve human health and respect the planetary boundaries. The Planetary Health Diet Index (PHDI) was developed with the purpose of evaluate the adherence to this reference diet. The aim of the present study was to evaluate the association between adherence to the EAT-Lancet diet with cardiometabolic risk profile., Methods: We used the cross-sectional baseline data from 14,155 participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter ongoing cohort study. Dietary data were collected using a 114-item validated food frequency questionnaire. The PHDI was used to assess the adherence to the EAT-Lancet diet. It consists of 16 components and the total score can range from 0 to 150 points. Linear, logistic and quasi-Poisson regression models were built to evaluate the associations between PHDI and the outcomes., Results: Individuals with higher adherence to EAT-Lancet diet (PHDI, 5th quintile) had lower values for systolic blood pressure (β - 0.84; 95% CI - 1.66: - 0.01), diastolic blood pressure (β - 0.70; 95% CI - 1.24: - 0.15), total cholesterol (β - 3.15; 95% CI - 5.30: - 1.01), LDL-c (β - 4.10; 95% CI - 5.97: -  2.23), and non-HDL-cholesterol (β - 2.57; 95% CI - 4.62: - 0.52). No association was observed for HDL-c, triglycerides and HOMA-IR., Conclusions: Our results indicate that higher adherence to the EAT-Lancet diet is associated with lower levels of blood pressure, total cholesterol, LDL-c, and non-HDL-c., (© 2022.

Current data shows that the autonomic and vascular systems can influence each other. However, only a few studies have addressed this association in the general population. We aimed to investigate whether heart rate variability (HRV) was associated with coronary artery calcium (CAC) in a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We examined baseline data from 3138 participants (aged 35 to 74 years) without previous cardiovascular disease who underwent CAC score assessment and had validated HRV recordings. Prevalent CAC was defined as a CAC score>0, and HRV analyses were performed over 5-min segments. We detected CAC score>0 in 765 (24.4%) participants. Subgroup analyses in older participants (≥49 years) adjusted for sociodemographic and clinical variables revealed that CAC score>0 was associated with lower values of standard deviation of NN intervals (SDNN) (odds ratio [OR]=1.32; 95%CI: 1.05,1.65), root mean square of successive differences between adjacent NN intervals (RMSSD) (OR=1.28; 95%CI: 1.02,1.61), and low frequency (LF) (OR=1.53, 95%CI: 1.21,1.92). Interaction analysis between HRV indices and sex in age-stratified groups revealed significant effect modification: women showed increased OR for prevalent CAC in the younger group, while for men, the associations were in the older group. In conclusion, participants aged ≥49 years with low SDNN, RMSSD, and LF values were more likely to present prevalent CAC, suggesting a complex interaction between these markers in the pathogenesis of atherosclerosis. Furthermore, our results suggested that the relationship between CAC and HRV might be sex- and age-related.

Introduction: Metabolic Syndrome (MetS) and depression comorbidity has been recognized, but its directionality is still uncertain. The aims of this study was to assess the association between depression (diagnosis and severity) and MetS (components, diagnosis and trajectory) in the baseline and over a 4-year follow-up period., Material and Methods: Baseline and follow-up data from 13,883 participants of the Brazilian Longitudinal Study of Adult Health were analyzed. The Clinical Interview Schedule Revised assessed depressive episode and its severity. MetS components and diagnosis were assessed according to the National Cholesterol Education Program Adult Treatment Panel III. Participants were grouped according to MetS trajectory as recovered, incident and persistent MetS. Logistic regression analysis was conducted estimating odds ratios (OR) and 95% confidence intervals (95%CI)., Results: Baseline depression was positively associated with recovered (OR = 1.59, 95%CI 1.18-2.14), incident (OR = 1.45, 95%CI 1.09-1.91) and persistent (OR = 1.70, 95%CI 1.39-2.07) MetS. Baseline depression was also associated with large waist circumference (OR = 1.47, 95%CI 1.23-1.75), high triglycerides (OR = 1.23, 95%CI 1.02-1.49), low high-density lipoprotein cholesterol (OR = 1.30, 95%CI 1.08-1.56), and hyperglycemia (OR = 1.38, 95%CI 1.15-1.66) at follow-up. Having three or more MetS components at follow-up was associated with baseline depression, with a positive dose-response effect (OR = 1.77, 95%CI 1.29-2.43; OR = 1.79, 95%CI 1.26-2.54; OR = 2.27, 95%CI 1.50-3.46, respectively). The magnitude of associations was greater in severe depression, when compared to moderate and mild., Discussion: These results support that depression is a risk factor for the development of MetS and highlights the need to follow metabolic and cardiovascular alterations in the presence of depression., Competing Interests: Declaration of competing interest The authors declare no conflict of interest.

Introduction: The association of diabetes with subclinical thyroid diseases may increase the risk of cardiovascular diseases. We analyzed the association of subclinical hypothyroidism, diabetes, and both diseases with carotid Intima-Media Thickness (cIMT) as a surrogate maker for early cardiovascular disease in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)., Methods: Cross-sectional analysis with data from the 3 rd visit (2017‒2019). Linear regression models were used to evaluate the association of subclinical hypothyroidism, diabetes and of both diseases with a cIMT presented as Beta (95% Confidence Interval ‒ 95% CI) without adjustment, with adjustment for sociodemographic variables (Model 1) and multivariable adjustment (Model 1 more cardiovascular risk factors). We also used logistic regression models to analyze the Odds Ratio (OR) and 95% CI for the association of both diseases using cIMT > P75%., Results: After the exclusion of patients with previous cardiovascular disease, 5,077 participants with no diseases, 1578 with diabetes, 662 with subclinical hypothyroidism, and 234 with both diseases were included in the analysis. Linear regression models showed an association of cIMT with only diabetes (β = 0.019; 95% CI 0.012 to 0.027; p < 0.0001) and subclinical hypothyroidism more diabetes (β = 0.03; 95% CI 0.010‒0.047, p < 0.0001). The logistic regression model reported an association between diabetes and CIMT higher than P75% (OR = 1.49, 95% CI 1.30‒1.71). No interaction between diabetes and subclinical hypothyroidism was detected using cIMT respectively as a continuous (p = 0.29) or as a categorical variable (p = 0.92)., Discussion: Diabetes was associated with higher cIMT values. However, no additive effect of subclinical hypothyroidism associated with diabetes over cIMT was detected., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 HCFMUSP.

Background: There is mixed evidence on increasing rates of psychiatric disorders and symptoms during the coronavirus disease 2019 (COVID-19) pandemic in 2020. We evaluated pandemic-related psychopathology and psychiatry diagnoses and their determinants in the Brazilian Longitudinal Study of Health (ELSA-Brasil) São Paulo Research Center., Methods: Between pre-pandemic ELSA-Brasil assessments in 2008-2010 (wave-1), 2012-2014 (wave-2), 2016-2018 (wave-3) and three pandemic assessments in 2020 (COVID-19 waves in May-July, July-September, and October-December), rates of common psychiatric symptoms, and depressive, anxiety, and common mental disorders (CMDs) were compared using the Clinical Interview Scheduled-Revised (CIS-R) and the Depression Anxiety Stress Scale-21 (DASS-21). Multivariable generalized linear models, adjusted by age, gender, educational level, and ethnicity identified variables associated with an elevated risk for mental disorders., Results: In 2117 participants (mean age 62.3 years, 58.2% females), rates of CMDs and depressive disorders did not significantly change over time, oscillating from 23.5% to 21.1%, and 3.3% to 2.8%, respectively; whereas rate of anxiety disorders significantly decreased (2008-2010: 13.8%; 2016-2018: 9.8%; 2020: 8%). There was a decrease along three wave-COVID assessments for depression [ β = -0.37, 99.5% confidence interval (CI) -0.50 to -0.23], anxiety ( β = -0.37, 99.5% CI -0.48 to -0.26), and stress ( β = -0.48, 99.5% CI -0.64 to -0.33) symptoms (all p s < 0.001). Younger age, female sex, lower educational level, non-white ethnicity, and previous psychiatric disorders were associated with increased odds for psychiatric disorders, whereas self-evaluated good health and good quality of relationships with decreased risk., Conclusion: No consistent evidence of pandemic-related worsening psychopathology in our cohort was found. Indeed, psychiatric symptoms slightly decreased along 2020. Risk factors representing socioeconomic disadvantages were associated with increased odds of psychiatric disorders.

Background: Diabetes is an important public health problem due to its health impairments and high costs for health services. We analyzed the relationship between the domains of physical activity at leisure-time (LTPA) and at commuting (CPA) with diabetes and pre-diabetes in an ELSA-Brasil study., Methods: Data from 11,797 participants (52.5% women, 49.1 ± 7.2 years) were analyzed. LTPA and CPA were measured using the International Physical Activity Questionnaire. Diabetes and pre-diabetes were defined by medical history, medication use to treat diabetes or blood glucose. Logistic regression models were performed to estimate the association between LTPA and CPA with diabetes and pre-diabetes after adjustment for sociodemographic and cardiovascular risk factors., Results: The prevalence of LTPA and CPA was 24.4% and 34%, respectively. Physically active participants at LTPA were less likely to have pre-diabetes (OR = 0.86 [95% CI = 0.77-0.95]) and diabetes (OR = 0.80 [95% CI = 0.69-0.93]), compared with inactive participants. No association between CPA and diabetes/pre-diabetes was observed. LTPA was inversely associated with diabetes among men (OR = 0.73 [95% CI = 0.60-0.89]), but was not associated among women. Women who were active (OR = 0.78 [95% CI = 0.67-0.90]) (OR = 0.79 [95% CI = 0.65-0.95]) at LTPA were less likely to have pre-diabetes, than inactive women., Conclusion: LTPA was inversely associated with diabetes and pre-diabetes in the ELSA-Brasil participants. A different behavior was observed between genders.

Aim: To estimate the association between consumption of sugar-sweetened soft drinks and unsweetened fruit juice with metabolic syndrome (MetS) and its components in participants of the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) after 4 years of follow-up., Methods: We used data from ELSA-Brasil cohort (N = 15,105). The sample consisted of 6,124 civil servants free of the MetS at baseline (35 to 74 years, both sexes). The consumption of sugar-sweetened soft drinks and unsweetened fruit juice was estimated by a food frequency questionnaire previously validated. The outcome was MetS and its components (Joint Interim Statement criteria). To test the association between beverage consumption at baseline (2008-2010) and MetS and its components at follow-up (2012-2014), we used Poisson regression models with robust variance adjusting for potential confounders., Results: After 4-year follow-up, the higher consumption of sugar-sweetened soft drinks (≥ 1 serving/day = 250 mL/day) increased the relative risk of MetS (RR = 1.22; 95% CI 1.04-1.45), high fasting glucose (RR = 1.23; 95% CI 1.01-1.48), and high blood pressure (RR = 1.23; 95% CI 1.00-1.54). Moderate consumption of this beverage (0.4 to < 1 serving/day) increased the relative risk of high waist circumference (WC) (RR = 1.21; 95% CI 1.02-1.42). After adjustment for confounding variables, the consumption of unsweetened fruit juice was not associated with the MetS and its components., Conclusion: Higher sugar-sweetened soft drinks consumption was associated with a higher risk relative of MetS, high fasting glucose, and high blood pressure, while moderate consumption of this beverage increased the relative risk of high WC in Brazilian adults., (© 2022.

Background: Atrial fibrillation (AF) negatively impacts health systems worldwide. We aimed to capture perceptions of and barriers and facilitators for AF care in Brazilian primary care units (PCUs) from the perspective of healthcare professionals (HCPs)., Methods: This mixed-methods, cross-sectional study utilised an exploratory sequential design, beginning with the quantitative data collection (up to 18 closed questions) immediately followed by a semi-structured interview. HCPs were recruited from 11 PCUs in the Sao Paulo region and included managers, physicians, pharmacists, nurses and community health agents. Descriptive statistics were used to present findings from the quantitative questionnaire and inductive analysis was used to identify themes from the qualitative data., Results: One hundred seven HCPs were interviewed between September 2019 and May 2020. Three main themes were identified that encapsulated barriers and facilitators to AF care: access to care (appointments, equipment/tests and medication), HCP and patient roles (HCP/patient relationship and patient adherence) and the role of the organisation/system (infrastructure, training and protocols/guidelines). Findings from the qualitative analysis reinforced the quantitative findings, including a lack of AF-specific training for HCPs, protocols/guidelines on AF management, INR tests in the PCUs, patient knowledge of AF management and novel oral anticoagulants (NOACs) as key barriers to optimal AF care., Conclusions: Development and implementation of AF-specific training for PCU HCPs are needed in Brazil, along with evidence-based protocols and guidelines, educational programmes for patients, better access to INR tests for patients taking warfarin and availability of NOACs., (© 2022.

In recent decades, different data-driven approaches have emerged to identify dietary patterns (DP) and little is discussed about how these methods are able to capture diet complexity within the same population. This study aimed to apply three statistical methods to identify the DP of the Longitudinal Study of Adult Health (ELSA-Brasil) population and evaluate the similarities and differences between them. Dietary data were assessed at baseline in the ELSA-Brasil study using a FFQ. DP were identified by applying three statistical methods: (1) factor analysis (FA), (2) treelet transform (TT) and (3) reduced rank regression (RRR). The characteristics of individuals classified in the last tertile of each DP were compared. Cross-classification and Pearson's correlation coefficients were assessed to evaluate the agreement between individuals' adherence to DP of the three methods. A similar convenience DP was identified for all three methods. FA and TT also identified a similar prudent DP and a DP highly loaded for the food groups rice and beans. Individuals classified in the third tertile of similar DP of each method presented similar socio-demographic and nutrient intake characteristics. Regarding the cross-classification, prudent DP from FA and TT presented a higher level of agreement (75 %), while convenience DP from TT and RRR presented the lowest agreement (44·8 %). The different statistical methods were able to capture the populations' DP in a similar way while highlighting the particularities of each method.

Purpose: This study evaluated the association between coffee consumption and serum lipid profile in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)., Methods: This is a cross-sectional study on baseline data from participants of the cohort ELSA-Brasil. Only participants of São Paulo Research Center who underwent a nuclear magnetic resonance (NMR) spectroscopy examination of lipid profile were included (N = 4736). Coffee intake was categorized into four categories (cups/day, in reference cup size of 50 mL, which is the household measure adopted in Brazil): never/almost never, ≤ 1, 1-3, and > 3. Serum lipid profile [i.e., Total Cholesterol (TC), Total Triglycerides (TG), Very Low-Density Lipoprotein-cholesterol (VLDL-c), Low-Density Lipoprotein-cholesterol (LDL-c), High-Density Lipoprotein-cholesterol (HDL-c), Triglyceride-rich Lipoprotein Particles (TRLP) and subfractions particles] was analyzed. To estimate the effect of coffee consumption on serum lipid profile, multivariate Generalized Linear Models were performed., Results: Compared to participants who never or almost never drink coffee, individuals who consumed more than 3 cups/day showed an increase in concentrations of TC (β: 4.13; 95% CI 0.81, 7.45), TG (β: 9.53; 95% CI 1.65, 17.42), VLDL-c (β: 1.90; 95% CI 0.38, 3.42), TRLP (β: 8.42; 95% CI 1.24, 15.60), and Very Small-TRLP and Medium-TRLP subfractions (β: 7.36; 95% CI 0.21, 14.51; β: 2.53; 95% CI 0.89, 4.16, respectively), but not with HDL-c and LDL-c. Among individuals with low (≤ 1 cup/day) and moderate (1-3 cups/day) coffee consumption, no significant associations with lipids was observed., Conclusion: High coffee consumption (more than 3 cups per day) was associated with an increase in serum lipids, namely TC, TG, VLDL-c, and TRL particles, highlighting the importance of a moderate consumption of this beverage., (© 2022.

Aim: Evidence indicates most people were resilient to the impact of the COVID-19 pandemic on mental health. However, evidence also suggests the pandemic effect on mental health may be heterogeneous. Therefore, we aimed to identify groups of trajectories of common mental disorders' (CMD) symptoms assessed before (2017-19) and during the COVID-19 pandemic (2020-2021), and to investigate predictors of trajectories., Methods: We assessed 2,705 participants of the ELSA-Brasil COVID-19 Mental Health Cohort study who reported Clinical Interview Scheduled-Revised (CIS-R) data in 2017-19 and Depression Anxiety Stress Scale-21 (DASS-21) data in May-July 2020, July-September 2020, October-December 2020, and April-June 2021. We used an equi-percentile approach to link the CIS-R total score in 2017-19 with the DASS-21 total score. Group-based trajectory modeling was used to identify CMD trajectories and adjusted multinomial logistic regression was used to investigate predictors of trajectories., Results: Six groups of CMD symptoms trajectories were identified: low symptoms (17.6%), low-decreasing symptoms (13.7%), low-increasing symptoms (23.9%), moderate-decreasing symptoms (16.8%), low-increasing symptoms (23.3%), severe-decreasing symptoms (4.7%). The severe-decreasing trajectory was characterized by age < 60 years, female sex, low family income, sedentary behavior, previous mental disorders, and the experience of adverse events in life., Limitations: Pre-pandemic characteristics were associated with lack of response to assessments. Our occupational cohort sample is not representative., Conclusion: More than half of the sample presented low levels of CMD symptoms. Predictors of trajectories could be used to detect individuals at-risk for presenting CMD symptoms in the context of global adverse events., (© 2022.

This study aimed to predict dietary recommendations and compare the performance of algorithms based on collaborative filtering for making predictions of personalized dietary recommendations. We analyzed the baseline cross-sectional data (2008-2010) of 12,667 participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The participants were public employees of teaching and research institutions, aged 35-74 years, and 59% female. A semiquantitative Food Frequency Questionnaire (FFQ) was used for dietary assessment. The predictions of dietary recommendations were based on two machine learning (ML) algorithms-user-based collaborative filtering (UBCF) and item-based collaborative filtering (IBCF). The ML algorithms had similar precision (88-91%). The error metrics were lower for UBCF than for IBCF: with a root mean square error (RMSE) of 1.49 vs. 1.67 and a mean square error (MSE) of 2.21 vs. 2.78. Although all food groups were used as input in the system, the items eligible as recommendations included whole cereals, tubers and roots, beans and other legumes, oilseeds, fruits, vegetables, white meats and fish, and low-fat dairy products and milk. The algorithms' performances were similar in making predictions for dietary recommendations. The models presented can provide support for health professionals in interventions that promote healthier habits and improve adherence to this personalized dietary advice.

Objective: Although relatively costly and non-scalable, non-invasive neuromodulation interventions are treatment alternatives for neuropsychiatric disorders. The recent developments of highly-deployable transcranial electric stimulation (tES) systems, combined with mobile-Health technologies, could be incorporated in digital trials to overcome methodological barriers and increase equity of access. The study aims are to discuss the implementation of tES digital trials by performing a systematic scoping review and strategic process mapping, evaluate methodological aspects of tES digital trial designs, and provide Delphi-based recommendations for implementing digital trials using tES., Methods: We convened 61 highly-productive specialists and contacted 8 tES companies to assess 71 issues related to tES digitalization readiness, and processes, barriers, advantages, and opportunities for implementing tES digital trials. Delphi-based recommendations (>60% agreement) were provided., Results: The main strengths/opportunities of tES were: (i) non-pharmacological nature (92% of agreement), safety of these techniques (80%), affordability (88%), and potential scalability (78%). As for weaknesses/threats, we listed insufficient supervision (76%) and unclear regulatory status (69%). Many issues related to methodological biases did not reach consensus. Device appraisal showed moderate digitalization readiness, with high safety and potential for trial implementation, but low connectivity., Conclusions: Panelists recognized the potential of tES for scalability, generalizability, and leverage of digital trials processes; with no consensus about aspects regarding methodological biases., Significance: We further propose and discuss a conceptual framework for exploiting shared aspects between mobile-Health tES technologies with digital trials methodology to drive future efforts for digitizing tES trials., (Copyright © 2022 International Federation of Clinical Neurophysiology.

Background: Metabolic syndrome (MetS) and common mental disorders are prevalent conditions. However, the relationship of MetS and its components with depression, anxiety, and common mental disorders has not been sufficiently addressed in low-/middle-income countries., Objective: To investigate whether depression, anxiety, and common mental disorders are associated with MetS and its components in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)., Methods: A cross-sectional analysis of the ELSA-Brasil baseline visit (2008-2010) was performed. Adults without cardiovascular diseases had their MetS status defined by the National Cholesterol Education Program's Adult Treatment Panel III criteria. We assessed mental disorders using the Clinical Interview Schedule-Revised. We employed multiple logistic regression models adjusted for sociodemographic and behavioral factors. The dependent variables were mental disorders, and the independent variables were MetS and its components. We also performed analyses stratified by age and gender., Results: Our sample included 12,725 participants (54.9% women, mean age of 51.8 ± 8.9 y). MetS and depressive disorders were significantly associated (odds ratio [OR] = 1.55, 95% confidence interval [CI] 1.30-1.85). Increased abdominal circumference (OR = 1.54, 95% CI 1.29-1.84), diabetes mellitus (OR = 1.24, 95% CI 1.02-1.50), hypertriglyceridemia (OR = 1.33, 95% CI 1.11-1.60), and low high-density lipoprotein cholesterol (only when adjusted for sociodemographic factors) (OR = 1.25, 95% CI 1.02-1.52) were also associated with depression. This association remained significant for all stratified analyses. Finally, MetS was also significantly associated with anxiety disorders (OR = 1.19, 95% CI 1.07-1.32) and common mental disorders (OR = 1.27, 95% CI 1.17-1.39)., Conclusions: Our cross-sectional findings suggested that depression, anxiety, and common mental disorder are associated with MetS. Depression was also associated with abdominal obesity, elevated blood glucose, elevated triglycerides, and reduced high-density lipoprotein cholesterol, but not with hypertension., (Copyright © 2022 Academy of Consultation-Liaison Psychiatry.

Background: Machine learning investigates how computers can automatically learn. The present study aimed to predict dietary patterns and compare algorithm performance in making predictions of dietary patterns., Methods: We analysed the data of public employees (n = 12,667) participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The K-means clustering algorithm and six other classifiers (support vector machines, naïve Bayes, K-nearest neighbours, decision tree, random forest and xgboost) were used to predict the dietary patterns., Results: K-means clustering identified two dietary patterns. Cluster 1, labelled the Western pattern, was characterised by a higher energy intake and consumption of refined cereals, beans and other legumes, tubers, pasta, processed and red meats, high-fat milk and dairy products, and sugary beverages; Cluster 2, labelled the Prudent pattern, was characterised by higher intakes of fruit, vegetables, whole cereals, white meats, and milk and reduced-fat milk derivatives. The most important predictors were age, sex, per capita income, education level and physical activity. The accuracy of the models varied from moderate to good (69%-72%)., Conclusions: The performance of the algorithms in dietary pattern prediction was similar, and the models presented may provide support in screener tasks and guide health professionals in the analysis of dietary data., (© 2022 The British Dietetic Association Ltd.)

Abstract: Musculoskeletal pain is a global health concern, and work-related psychosocial stress might be a potential contributing factor. This cross-sectional study investigates whether job stress is associated with chronic and widespread musculoskeletal pain in 2051 Brazilian active civil servants included in the Brazilian Longitudinal Study of Adult Health Musculoskeletal (ELSA-Brasil MSK). Job stress was assessed using the Effort-Reward Imbalance (ERI) questionnaire. Associations between ERI domains, categorized into tertiles, and chronic musculoskeletal pain (CMP) at any site and per number of affected sites (0, 1-2, ≥3-multisite pain) and body regions (0, 1-2, 3-generalized pain), were investigated using binary and multinomial logistic regression, adjusted for sociodemographic, occupational, and health covariates. The prevalence of CMP at any site, multisites, and generalized regions was 52.9%, 18.2%, and 9.5%, respectively. After adjustments, the lower the reward and the greater the overcommitment, the higher the odds of CMP at any site. The ERI domains were more strongly associated with multisite and generalized CMP than with CMP at any site. Multisite CMP was associated with lower reward and with greater effort, overcommitment, and effort-reward imbalance ratio. Chronic musculoskeletal pain according to body regions, especially generalized pain, was also associated with ERI domains effort (OR = 2.06; 95%CI = 1.33-3.21), overcommitment (OR = 3.44; 95%CI = 2.20-5.39), and effort-reward imbalance ratio (OR = 2.06; 95%CI = 1.30-3.27). Results reveal an association between job stress not only with CMP at any site but notably with the pain spread to other body sites or regions. Our findings suggest that lowering stress at work and discouraging overcommitment may help reduce the CMP burden, including reduction of CMP spread from one site or region of the body to another., (Copyright © 2022 International Association for the Study of Pain.)

Background: Advances in technology have led to the identification of a greater number of metabolites related to diet. Although fruit intake biomarkers have been reported in some studies, these findings require further replication, considering the relevance of fruits for diet quality and health., Objectives: The aim of this study was to explore the associations of a set of potential urinary biomarkers of diet, assessed using a targeted metabolomics approach, with self-reported fruit intake data in participants of a computer-assisted 24-h dietary recall (GloboDiet software) validation study., Methods: A total of 93 individuals aged 43-72 y, 54% female, participated in this study. The subjects were a subsample of the Longitudinal Study of Adult Health (ELSA-Brasil). A 24-h dietary recall was obtained with the aid of GloboDiet software matching a 24-h urine sample from each participant. Candidate biomarkers were selected in a literature search and identified in urine by LC coupled to high-resolution MS. Spearman correlation analyses were performed between fruit intake and each biomarker., Results: Spearman correlation analysis showed that total fruits intake was significantly correlated with citric acid (ρ = 0.213, P = 0.041), ferulic acid sulfate I (ρ = 0.240, P = 0.020), hesperetin glucuronide/homoeriodictyol glucuronide (ρ = 0.303, P = 0.003), hydroxyhippuric acid (ρ = 0.239, P = 0.021), homovanillic alcohol sulfate (ρ = 0.339, P = 0.001), methylgallic acid sulfate (ρ = 0.268, P = 0.009), naringenin glucuronide (NG; ρ = 0.278, P = 0.007), proline betaine (PB; ρ = 0.305, P = 0.003), syringic acid sulfate (ρ = 0.210, P = 0.044), and sinapic acid sulfate (ρ = 0.412, P < 0.001). Among them, 3 have been described in literature as promising biomarkers for intake of total fruit, oranges, and citrus fruit: NG, hesperetin glucuronide, and PB., Conclusions: Associations of total fruits intake with urinary measurements indicate the potential usefulness of dietary biomarkers in the Brazilian population as a complement to self-reported dietary assessments., (© The Author(s) 2022.

Aim: To investigate the association between medication use and long-term all-cause mortality in a Brazilian stroke cohort., Methods: Both ischemic and hemorrhagic stroke were evaluated. Medication use was assessed as: never, only pre-stroke, only post-stroke, and continuous use. We evaluated anti-hypertensives, anti-diabetics, lipid-lowering drugs, anti-platelets, and anti-coagulants. Cox regression models were adjusted for sociodemographic and cardiovascular risk factors., Results: Among 1173 incident stroke cases (median age: 68; 86.8% were ischemic, 70% first-ever stroke), medication use was low (overall: 17.5% pre-stroke, 26.4% post-stroke, and 40% were under continuous use). Anti-hypertensives and anti-platelets (aspirin) were the continuous cardiovascular medications used most often, at 83.5% and 72%, respectively, while statins (39.7%) and anti-diabetics (31.3%) were the least used. Medication use (pre-stroke, post-stroke and continuous use) was associated with a reduction in all-cause mortality risk, particularly among those under continuous use (multivariable hazard ratio, 0.52; 95% confidence interval (CI), 0.46-0.66) compared with never-users. Among ischemic stroke patients, this effect was similar (multivariable hazard ratio, 0.52; 95% CI, 0.40-0.68). No significant associations were evident among hemorrhagic stroke patients., Conclusions: The risk of all-cause mortality was reduced by 48% among those with ischemic stroke under continuous use of medications. Secondary prevention should be emphasized more strongly in clinical practice. Geriatr Gerontol Int 2022; 22: 715-722., (© 2022 Japan Geriatrics Society.)

Objective: To estimate the associations of physical activity (PA) levels with migraine subtypes., Background: Physical activity has been associated with reduced migraine prevalence, but less is known about its relationship with migraine subtypes and PA levels as recommended by World Health Organization (WHO)., Methods: In this cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we estimated the odds ratios (ORs) of migraine with aura (MA) and migraine without aura (MO), compared to participants without headaches, according to PA levels in the leisure time (LTPA), commuting time (CPA), and combined PA domains., Results: In total, 2773 participants provided complete data, 1556/2773 (56.1%) were women, mean (SD) age of 52.3 (9.1) years. In this study's sample, 1370/2773 (49.4%) participants had overall migraine, 480/2773 (17.3%) had MA, and 890/2773 (32.0%) had MO. In the LTPA domain, there were reduced odds of MA (OR 0.72, 95% confidence interval [CI] 0.53-0.96; p = 0.030) and MO (OR 0.71, 95% CI 0.56-0.90; p = 0.005) in participants who met the WHO PA guidelines after adjustment for confounder variables. In the analyses stratified by intensity, moderate LTPA was associated with reduced odds of MA (OR 0.56, 95% CI 0.320-0.99; p = 0.049), while vigorous LTPA was associated with reduced odds of MO (OR 0.55, 95% CI 0.395-0.77; p = 0.001). There were no significant associations between migraine subtypes and CPA or combined PA domains. In the whole migraine sample, meeting the WHO PA guidelines in the LTPA (OR 0.275, 95% CI 0.083-0.90; p = 0.034), CPA (OR 0.194, 95% CI 0.064-0.58; p = 0.004), and combined domains (OR 0.115, 95% CI 0.032-0.41; p = 0.001) was associated with reduced odds of daily migraine attack frequency., Conclusions: Meeting the WHO PA guidelines for LTPA, but not CPA or combined PA domains, is associated with lower migraine occurrence. Moderate LTPA favors MA reduction, while vigorous LTPA favors MO reduction., (© 2022 American Headache Society.)

Objectives: Using multiple drugs with anticholinergic properties is common and might lead to cumulative anticholinergic toxicity and increased risk of cognitive impairment. Therefore, we sought to investigate the association between the Anticholinergic Cognitive Burden (ACB) Scale and cognitive performance among middle-aged and older adults., Methods: In this cross-sectional study with 13,065 participants from the baseline visit of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), mean age was 51.7 ± 9.0 years old, 55% women, and 53% white. The ACB was calculated based on the medications in use. We investigated the association of ACB with global cognition and memory, verbal fluency (VF), and trail-making test version B (TMT-B) z-scores, using multiple linear regression models adjusted for sociodemographic and clinical variables., Results: Overall, 16% of participants had an ACB score greater than 0. ACB was associated with poor cognitive performance in all tests in crude analysis. After adjustment for sociodemographic characteristics, the association remained significant for the global cognitive score, as well as the memory and the TMT-B z-scores. However, after further adjustments for clinical variables, only trend associations of ACB with poor memory (β =  - 0.02, 95% Cl =  - 0.05, 0.00, p = 0.056) and the TMT-B z-scores (β =  - 0.02, 95% Cl =  - 0.04, 0.00, p = 0.054) were found. In stratified analyses by age groups, ACB was associated with poor cognitive performance on the TMT-B (β =  - 0.03, 95% Cl =  - 0.05, - 0.01, p = 0.005) in individuals aged less than 65 years old., Conclusion: Although the ACB was associated with poor executive function only among middle-aged adults in adjusted analysis, residual confounding may partly explain our results., (© 2022.

Background: Most of the few studies that have established reference ranges for serum uric acid (SUA) have not taken into account factors which may interfere with its levels and followed rigorous laboratory quality standards. The aim of this study was to establish reference ranges for SUA and determine the prevalence of hyperuricemia., Method: Cross-sectional study including 15,100 participants (all sample) aged 35 to 74 years from baseline data of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicentric cohort of volunteer civil servants from five universities and one research institute located in different regions of Brazil. It was established a reference sample excluding participants with factors that directly influence SUA levels: glomerular filtration rate lower than 60 ml/min, excessive alcohol intake, use of diuretics, aspirin, estrogen or urate-lowering therapy. SUA was measured using the uricase method and following rigorous international quality standards. Reference ranges were defined as values between percentiles 2.5 (P2.5) and 97.5 (P97.5) of SUA distribution in the reference sample, stratified by sex. Hyperuricemia was defined as SUA ≥ 7 mg/100 ml in the all sample., Results: The reference sample was composed of 10,340 individuals (55.3% women, median age 50 years). Reference ranges (P2.5 to P97.5) for SUA were: 4.0 to 9.2 mg/100 ml for men and 2.8 to 6.9 mg/100 ml for women. Sex was a major determinant for SUA levels (median [IQR], mg/100 ml: 6.1 [5.3-7.0] for men versus 4.5 [3.9-5.3] for women, p < 0.001). Higher levels of SUA were found in patients with higher BMI. Higher age had (a modest) influence only for women. The prevalence of hyperuricemia for all sample (N = 15,100) was 31.9% (95% confidence interval [CI] 30.8-33.0%) in men and 4.8% (95% CI 4.3-5.3%) in women., Conclusion: SUA reference ranges were 4.0 to 9.2 mg/100 ml for men and 2.8 to 6.9 mg/100 ml for women. Prevalence of hyperuricemia was 31.9% in men and 4.8% in women. Updated SUA reference ranges and prevalence of hyperuricemia are higher nowadays and might be used to guide laboratories and the screening for diseases related to SUA., (© 2022. The Author(s).)

Background: LDL appears to drive atherogenesis in overt hypothyroidism, but in subclinical dysfunction, its role is not completely elucidated., Objective: The aim of this study was to evaluate subfractions of LDL in subclinical (SC) thyroid disorders., Methods: Individuals were divided into three groups by baseline thyroid function (SC hypothyroidism, euthyroidism, and SC hyperthyroidism). LDL particle (LDL-P) subfractions were analyzed by Nuclear Magnetic Resonance (NMR) spectroscopy. The association between LDL-P subfractions and thyroid groups and quintiles was evaluated by linear regression models., Results: We evaluated 3304 participants (54.1% women, 51.2% white, mean age 50.6 ± 8.7 years). In the univariate analysis, small LDL particle concentrations (SLDL-P) were not different between SC hypo- and hyperthyroidism compared to euthyroid individuals (p = 0.485 and p = 0.314, respectively). Large LDL-P (LDL-P) levels also did not differ in SC hyperthyroidism and SC hypothyroidism compared to euthyroidism (p = 0.698 and 0.788 respectively). Intermediate LDL-P levels were not different across the groups. These numbers did not materially change in multivariate analysis. However, we also analyzed LDL subfractions according to quintiles of TSH. We showed that in the higher TSH quintile LDL subfractions presented a significantly smaller mean size of LDL subfractions compared to the first quintile., Conclusions: SC thyroid disorders are not associated with significant changes in LDL-P subfractions measured by NMR spectroscopy. However, it seems that the LDL mean size decreases as TSH levels increase, which may represent a more atherogenic lipid profile., (Copyright © 2022. Published by Elsevier Inc.)

Objective: To evaluate the past 2-week headache disability and explore its association with lifestyle factors, health perception, and mental disorder symptoms in the PNS 2013 survey., Background: The prevalence of headache disorders has been associated with lifestyle factors, mental disorders, and health perception. However, less is known regarding their influence on headache-related disability., Methods: In a cross-sectional analysis, chi-squared tests and logistic regression models computed the associations between headache-related disability (defined as days lost from work, school, or household chores in the past 2 weeks) and the variables of interest, compared to other disease-related disabilities groups or no day lost group. The adjusted models controlled for the effects of age, sex, income, and educational levels., Results: In the sample aged ≥ 18 years (n = 145,580), 10,728 (7.4%) participants reported any disease-related disability in the past 2 weeks (median interquartile range (IQR) for age = 47 (33-59) years, 62% women), with the median (IQR) days lost = 5 (2-14). Headache disability represented 5.3% (572/10,728) of all diseases, constituting the 4th most prevalent disease-related disability [median (IQR) days lost = 3 (3-4)]. Among people aged 18-25 years, headache disorders ranked 2nd as the most prevalent disability (13%), headache-related disability positively associated with physical inactivity, poorer health perception, and frequent mental disorders symptoms, and negatively associated with overweight, obesity, and alcohol consumption., Conclusion: Headache disability represents a leading cause of disease-related disability in Brazil and associates with unhealthy lifestyle factors, poorer health perception, and frequent mental disorder symptoms., (© 2021.

Background: Optimum functioning of the central nervous system is dependent on a wide range of nutrients, so mental illness can be impacted by diet via several mechanisms. We aimed to investigate the associations of antioxidants (vitamin A, C and E, and selenium and zinc) and vitamin B complex (B6, folate and B12) intake with depression in 14,737 subjects of the Brazilian Longitudinal Study of Adult Health., Methods: Baseline cross-sectional data was analyzed. Micronutrients intake was measured using the Food Frequency Questionnaire, and depression was assessed using the Clinical Interview Schedule Revised. Logistic regression models were built using daily intake quintiles of micronutrients., Results: A significant inverse relationship was observed between depression and higher intake of selenium, zinc, vitamins B6 and B12 for the total sample. Among women, a similar pattern of associations was observed, in addition to the higher intake of vitamins A and C. Among men, a significant inverse relationship between depression was observed only with the intake of vitamins B12 and B6. Higher total antioxidant intake was significantly associated with lower odds of depression and an inverse dose-response effect between total antioxidant intake and clinical severity of depression was observed among women, in adjusted models., Limitations: Recall bias in assessing diet. Misclassification bias regarding current depression., Conclusions: Depression is associated with lower intake of antioxidants and B vitamins. Higher intake of selected micronutrients may contribute to reduce depression occurrence and severity., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Background: Atrial fibrillation is a predictor of poor prognosis after stroke., Aims: To evaluate atrial fibrillation and all-cause and cardiovascular mortality in a stroke cohort with low socioeconomic status, taking into consideration oral anticoagulant use during 12-year follow-up., Methods: All-cause mortality was analyzed by Kaplan-Meier survival curve and Cox regression models to estimate hazard ratios and 95% confidence intervals (95% CI). For specific mortality causes, cumulative incidence functions were computed. A logit link function was used to calculate odds ratios (OR) with 95% CIs. Full models were adjusted by age, sex, oral anticoagulant use (as a time-dependent variable) and cardiovascular risk factors., Results: Of 1121 ischemic stroke participants, 17.8% had atrial fibrillation. Overall, 654 deaths (58.3%) were observed. Survival rate was lower (median days, interquartile range-IQR) among those with atrial fibrillation (531, IQR: 46-2039) vs . non-atrial fibrillation (1808, IQR: 334-3301), p -log rank < 0.0001). Over 12-year follow-up, previous atrial fibrillation was associated with increased mortality: all-cause (multivariable hazard ratios, 1.82; 95% CI: 1.43-2.31) and cardiovascular mortality (multivariable OR, 2.07; 95% CI: 1.36-3.14), but not stroke mortality. In the same multivariable models, oral anticoagulant use was inversely associated with all-cause mortality (oral anticoagulant time-dependent effect: multivariable hazard ratios, 0.47; 95% CI: 0.30-0.50, p  = 0.002) and stroke mortality (oral anticoagulant time-dependent effect ≥ 6 months: multivariable OR, 0.09; 95% CI: 0.01-0.65, p -value = 0.02), but not cardiovascular mortality., Conclusions: Among individuals with low socioeconomic status, atrial fibrillation was an independent predictor of poor survival, increasing all-cause and cardiovascular mortality risk. Long-term oral anticoagulant use was associated with a markedly reduced risk of all-cause and stroke mortality.

Background and Purpose: Early life socioeconomic status (SES) may impact cognitive performance later in life. We investigated the effect on cognitive performance of early life SES, education, and late life SES in the Brazilian Longitudinal Study of Adult Health., Methods: Path analysis was used to decompose associations between SES measures across the lifespan and cognition. The model included direct paths to cognition from early life SES, education, and late life SES, and indirect paths from early life passing through education and late life SES. We investigated whether the effects of early life SES are similar across middle-aged and older adults., Results: In 13,395 adults, the mean age was 51.5 (8.9) years, 54% were female, 53% were white, and 56% had at least college education. The direct path from early life SES remained significant in the presence of mediation paths through education, late life SES, or both, contributing to cognitive performance in both middle-aged and older adults. The indirect and total effect of early life SES was smaller for middle-aged compared to older adults. Early life SES continues to impact cognitive performance later in life independently of educational attainment and late life SES. The higher percent of mediation through education suggests that education may improve later life cognition even in the presence of low early life SES., Conclusions: Our results highlight the importance of public health initiatives to improve early life SES and education to foster cognitive aging in low- and middle-income countries., (© 2021 European Academy of Neurology.)
