Association of mental health symptoms with the migraine-tension-type headache spectrum in the Brazilian longitudinal study of adult health.

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.

Potential Determinants of Thyroid Peroxidase Antibodies and Mortality Risk: Results From the ELSA-Brasil Study.

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.

Liver steatosis as a predictor of incident diabetes in adults: a prospective evaluation in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Increasing epidemiological evidence suggests a bidirectional relationship between non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes, and that NAFLD may precede and/or promote the development of diabetes. This study aimed to investigate whether liver steatosis is associated with the incidence of diabetes in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The ELSA-Brasil is an occupational cohort study of active or retired civil servants, aged 35-74 years, in six capital cities in Brazil. We excluded participants with diabetes at baseline, those who reported excessive alcohol consumption or with missing information on relevant covariates, and those with self-referred hepatitis or cirrhosis. In total, 8,166 individuals participated, and the mean duration of follow-up was 3.8 years. The Cox proportional regression model was used to estimate the adjusted hazard ratio (HR) for the associations. Abdominal ultrasonography was used to detect liver steatosis. In the follow-up period, the cumulative incidence of diabetes was 5.25% in the whole sample, 7.83% and 3.88% in the groups with and without hepatic steatosis, respectively (p < 0.001). Compared to those without steatosis, individuals with hepatic steatosis had an increased risk of developing diabetes (HR = 1.31; 95%CI: 1.09-1.56) after adjustment for potential confounders, including body mass index (BMI). Hepatic steatosis was an independent predictor of incident diabetes in the ELSA-Brasil cohort study. Physicians should encourage changes in lifestyle and screen for diabetes in patients with fatty liver.

A pandemic toll in frail older adults: Higher odds of incident and persistent common mental disorders in the ELSA-Brasil COVID-19 mental health cohort.

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.

Adherence to the EAT-Lancet sustainable reference diet and cardiometabolic risk profile: cross-sectional results from the ELSA-Brasil cohort study.

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 (ß - 0.84; 95% CI - 1.66: - 0.01), diastolic blood pressure (ß - 0.70; 95% CI - 1.24: - 0.15), total cholesterol (ß - 3.15; 95% CI - 5.30: - 1.01), LDL-c (ß - 4.10; 95% CI - 5.97: -  2.23), and non-HDL-cholesterol (ß - 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.

Evidências epidemiológicas crescentes sugerem uma relação bidirecional entre a doença hepática gordurosa não alcoólica (DHGNA) e o diabetes tipo 2 e que a DHGNA pode preceder e/ou promover o desenvolvimento de diabetes. O objetivo deste estudo foi investigar se a esteatose hepática está associada à incidência de diabetes no Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). O ELSA-Brasil é um estudo de coorte ocupacional com servidores públicos ativos ou aposentados, com idades entre 35 e 74 anos, de seis capitais do Brasil. Foram excluídos os participantes com diabetes no início do estudo, aqueles que relataram consumo excessivo de álcool ou com falta de informações sobre covariáveis relevantes e indivíduos com hepatite ou cirrose autorreferida. No total, 8.166 indivíduos participaram e o tempo médio de seguimento foi de 3,8 anos. O modelo de regressão proporcional de Cox foi utilizado para estimar a razão de risco (HR) ajustada para as associações. A ultrassonografia abdominal foi utilizada para detectar esteatose hepática. No período de seguimento, a incidência cumulativa de diabetes foi de 5,25% em todo o grupo de participantes e de 7,83% e 3,88% nos grupos com e sem esteatose hepática, respectivamente (p < 0,001). Em comparação com aqueles sem esteatose, os indivíduos com esteatose hepática apresentaram um risco elevado de desenvolver diabetes (HR = 1,31; IC95%: 1,09-1,56) após o ajuste para potenciais fatores de confusão, incluindo o índice de massa corporal (IMC). A esteatose hepática foi um preditor independente de diabetes incidente no ELSA-Brasil. Os médicos devem incentivar mudanças no estilo de vida e a triagem para diabetes para pacientes com fígado gorduroso.

La creciente evidencia epidemiológica sugiere una relación bidireccional entre la enfermedad del hígado graso no alcohólica (EHGNA) y la diabetes tipo 2 y que la EHGNA puede preceder y/o desarrollar la diabetes. El objetivo de este estudio fue investigar si la esteatosis hepática está asociada con la incidencia de diabetes en el Estudio Longitudinal de Salud del Adulto (ELSA-Brasil). ELSA-Brasil es un estudio de cohorte ocupacional, realizado con funcionarios públicos activos o jubilados, con edades entre 35 y 74 años, de seis capitales en Brasil. Se excluyeron a los participantes con diabetes al inicio del estudio, aquellos que informaron consumir excesivamente alcohol o que carecían de información sobre las covariables relevantes, y los individuos con hepatitis o cirrosis autorreportada. En total participaron 8.166 sujetos, y el tiempo medio de seguimiento fue de 3,8 años. Se utilizó el modelo de regresión proporcional de Cox para estimar la razón de riesgo ajustada (HR) en las asociaciones. Se realizó ecografía abdominal para detectar esteatosis hepática. En el periodo de seguimiento, el grupo de participantes tuvo incidencia acumulada de diabetes del 5,25%, y en los grupos con y sin esteatosis hepática fueron del 7,83% y el 3,88%, respectivamente (p < 0,001). Los individuos con enfermedad de hígado graso tuvieron mayor riesgo de desarrollar diabetes (HR = 1,31; IC95%: 1,09-1,56) después de ajustar los posibles factores de confusión, incluido el índice de masa corporal (IMC), en comparación con aquellos sin esteatosis. La esteatosis hepática fue un predictor independiente de diabetes incidente en ELSA-Brasil. Los médicos deben alentar cambios en el estilo de vida y la detección de diabetes a los pacientes con hígado graso.

Lower paraoxonase 1 paraoxonase activity is associated with a worse prognosis in patients with non-ST-segment elevation myocardial infarction in long-term follow-up.

BACKGROUND: Acute coronary syndrome (ACS) is one of the main manifestations of coronary artery disease, with a higher prevalence and worst prognosis. Oxidative stress is important in atherosclerosis and ACS, and paraoxonase 1 (PON1) is directly related to reducing the effects of oxidative stress on lipoproteins. The present study evaluated the prognostic value of PON1 activity in patients with non-ST-segment elevation ACS [non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina (UA)], included in the ERICO study. METHODS: PON1 paraoxonase activity was determined in serum samples from 485 patients collected on admission. The prognostic value in the follow-up of up to 5 years was evaluated according to cutoff points established by tertiles. Kaplan-Meier curves and Cox regression were used for the analysis of all-cause mortality and cardiovascular mortality. RESULTS: The sample consisted mainly of elderly patients with a high frequency of cardiovascular risk factors. At follow-up of up to 5 years, there were 126 deaths from all causes (80 deaths from CVD). The lowest tertile of PON1 paraoxonase activity was associated with a higher risk of death in patients with NSTEMI, but not in patients with UA. CONCLUSION: PON1 paraoxonase activity has potential prognostic value in patients with NSTEMI.

Association between coffee consumption with serum lipid profile in ELSA-Brasil study: a metabolomic approach.

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 (ß: 4.13; 95% CI 0.81, 7.45), TG (ß: 9.53; 95% CI 1.65, 17.42), VLDL-c (ß: 1.90; 95% CI 0.38, 3.42), TRLP (ß: 8.42; 95% CI 1.24, 15.60), and Very Small-TRLP and Medium-TRLP subfractions (ß: 7.36; 95% CI 0.21, 14.51; ß: 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.

Thyroid-Stimulating Hormone and Thyroid Hormones and Incidence of Diabetes: Prospective Results of the Brazilian Longitudinal Study of Adult Health (ELSA-BRASIL).

Background: There are conflicting data regarding the association of thyroid function with incident diabetes. We prospectively investigated thyrotropin (TSH), free thyroxine (fT4), free triiodothyronine (fT3), and its conversion ratio (fT3:fT4) with the risk of developing diabetes in euthyroid subjects and those with subclinical thyroid dysfunction. Our hypothesis is that this relationship is a U-shaped curve since both subclinical thyroid diseases may be associated with diabetes. Methods: ELSA-Brasil is a highly admixed cohort study of 35-74 years old at baseline (2008-2010). Levels of TSH, fT4, fT3, and fT3:fT4 ratio were evaluated at baseline and incident diabetes was estimated over an 8.2-year follow-up (2017-2019). Diabetes was identified based on medical diagnosis, prescriptions, and laboratory tests. The risk of diabetes was evaluated according to quintiles of TSH, fT4, fT3, and fT3:fT4 ratio using Poisson regression with robust variance presented as relative risk (RR) with confidence interval [CI] of 95% after multivariable adjustment for sociodemographic and cardiovascular risk factors (reference third quintile), and as continuous variables. Results: We included 7948 participants (mean age, 50.2 [standard deviation 8.6] years; 54.4% female): 7177 euthyroid, 726 with subclinical hypothyroidism, and 45 with subclinical hyperthyroidism. Incidence of diabetes was 14.8%. No association was found for TSH, fT4, fT3, and fT3:fT4 ratio quintiles with incident diabetes. Using continuous variables, the increase of 1-unit (1-U) of fT4 decreased the risk of diabetes (RR 0.94 [CI 0.91-0.99]), while the increase of 1-U of the fT3:fT4 ratio increased the diabetes risk (RR 1.37 [CI 1.15-1.63]). The increase of 1-U of fT3 was associated with an increased risk of diabetes, but without significance after multivariable adjustment. In body mass index-stratified analysis, people with overweight or obesity presented a modest significantly higher risk of diabetes in the lowest quintile of fT4 (RR 1.04 [CI 1.01-1.07]) and an inverse association with incident diabetes in the first quintile of fT3:fT4 ratio (RR, 0.95 [CI 0.93-0.98]). The analyses using continuous variables presented similar findings. Conclusion: These findings suggest that fT4 and fT3 levels and the conversion rate might be additional risk factors associated with incident diabetes, especially in the presence of overweight or obesity. However, they need to be confirmed in future studies. (ClinicalTrials.gov Identifier: NCT02320461).

Consumption of alcoholic beverages and abdominal obesity: cross-sectional analysis of ELSA-Brasil. / Consumo de bebidas alcoólicas e obesidade abdominal: resultados da linha de base do ELSA-Brasil.

The objective was to analyze the association between alcohol consumption and abdominal adiposity in adults. Cross-sectional study conducted at baseline data from ELSA-Brasil (2008- 2010). The sample consisted of 15,065 civil servants from six education and research institutions (35 to 74 years old, both sexes). To identify central adiposity by measuring waist circumference (WC) and waist-to-hip ratio (WHR), the cutoff points recommended by the World Health Organization were used. Poisson regression models adjusted for potentially confounding variables were tested. About 40% of the sample had elevated WC and WHR. The probability of having elevated WC was 5% and 3% higher in the most exposed group of beer consumption in men and women when compared to the reference group [PR= 1.05 (95% CI 1.02-1.08) and P R= 1.03 (95% CI 1.00-1.07)]. A higher probability of having a high WHR was also found among the highest beer consumers [PR = 1.03 (95% CI 1.00-1.07) in men and PR = 1.10 (95% CI 1.04-1.15) in women]. A greater number of doses/week of alcoholic drink increased the probability of occurrence of high WC and WHR, with the beer contribution being more important.

Objetivou-se analisar a associação entre consumo de bebidas alcoólicas e adiposidade abdominal em adultos. Estudo transversal realizado com dados da linha de base do ELSA-Brasil (2008-2010). A amostra foi constituída por 15.065 servidores públicos de seis instituições de ensino e pesquisa (35 a 74 anos, ambos os sexos). Para identificar adiposidade central por meio das medidas de circunferência da cintura (CC) e relação cintura/quadril (RCQ), utilizou-se os pontos de corte preconizados pela Organização Mundial da Saúde. Para as análises estatísticas foi utilizado o teste qui-quadrado e modelos de regressão de Poisson ajustados por variáveis potencialmente confundidoras. Cerca de 40% da amostra apresentava CC e RCQ elevadas. A probabilidade de apresentar CC elevada foi 5% e 3% maior no grupo mais exposto de consumo de cerveja em homens e mulheres quando comparado ao grupo de referência [RP = 1,05 (IC 95% 1,02-1,08) e RP = 1,03 (IC 95% 1,00-1,07)]. Também foi encontrada maior probabilidade de apresentar RCQ elevada entre os maiores consumidores de cerveja [RP = 1,03 (IC 95% 1,00-1,07) em homens e RP=1,10 (IC 95% 1,04-1,15) em mulheres]. Maior número de doses/semana de bebida alcoólica aumentou a probabilidade de ocorrência de CC e RCQ elevadas, sendo mais importante a contribuição da cerveja.

Association between neck circumference and non-alcoholic fatty liver disease: cross-sectional analysis from ELSA-Brasil

Abstract BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a public health problem worldwide. Neck circumference (NC) is a simple anthropometric adiposity parameter that has been correlated with cardiometabolic disorders like NAFLD. OBJECTIVES: To investigate the association between NC and NAFLD, considering their obesity-modifying effect, among participants from the Longitudinal Study of Adult Health (ELSA-Brasil) baseline study. DESIGN AND SETTINGS: Cross-sectional study at the ELSA-Brasil centers of six public research institutions. METHODS: This analysis was conducted on 5,187 women and 4,270 men of mean age 51.8 (± 9.2) years. Anthropometric indexes (NC, waist circumference [WC] and body mass index [BMI]), biochemical and clinical parameters (diabetes, hypertension and dyslipidemia) and hepatic ultrasound were measured. The association between NC and NAFLD was estimated using multinomial logistic regression, considering potential confounding effects (age, WC, diabetes, hypertension and dyslipidemia). Effect modification was investigated by including the interaction term NC x BMI in the final model. RESULTS: The frequency of NAFLD and mean value of NC were 33.6% and 33.9 (± 2.5) cm in women, and 45.8% and 39.4 (± 2.8) cm in men, respectively. Even after all adjustments, larger NC was associated with a greater chance of moderate/severe NAFLD (1.16; 95% confidence interval [CI] for women; 1.05, 95% CI for men; P < 0.001). Presence of multiplicative interaction between NC and BMI (P < 0.001) was also observed. CONCLUSION: NC was positively associated with NAFLD in both sexes, regardless of traditional adiposity indexes such as BMI and WC. The magnitude of the association was more pronounced among women.

Examining the impact of the COVID-19 pandemic through the lens of the network approach to psychopathology: Analysis of the Brazilian Longitudinal Study of Health (ELSA-Brasil) cohort over a 12-year timespan.

Cohort studies have displayed mixed findings on changes in mental symptoms severity in 2020, when the COVID-19 pandemic outbreak started. Network approaches can provide additional insights by analyzing the connectivity of such symptoms. We assessed the network structure of mental symptoms in the Brazilian Longitudinal Study of Health (ELSA-Brasil) in 3 waves: 2008-2010, 2017-2019, and 2020, and hypothesized that the 2020 network would present connectivity changes. We used the Clinical Interview Scheduled-Revised (CIS-R) questionnaire to evaluates the severity of 14 common mental symptoms. Networks were graphed using unregularized Gaussian models and compared using centrality and connectivity measures. The predictive power of centrality measures and individual symptoms were also estimated. Among 2011 participants (mean age: 62.1 years, 58% females), the pandemic symptom 2020 network displayed higher overall connectivity, especially among symptoms that were related to general worries, with increased local connectivity between general worries and worries about health, as well as between anxiety and phobia symptoms. There was no difference between 2008 and 2010 and 2017-2019 networks. According to the network theory of mental disorders, external factors could explain why the network structure became more densely connected in 2020 compared to previous observations. We speculate that the COVID-19 pandemic and its innumerous social, economical, and political consequences were prominent external factors driving such changes; although further assessments are warranted.

Adherence to the Planetary Health Diet Index and Obesity Indicators in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

The EAT-Lancet Commission has proposed a model diet to improve the health of human beings and that of the planet. Recently, we proposed the Planetary Health Diet Index (PHDI) to assess adherence of the population to this model diet. In this study, we aimed to evaluate adherence to the PHDI and obesity outcomes using baseline data from 14,515 participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The dietary data were assessed using a 114-item FFQ. Body mass index (BMI) and waist circumference (WC) were both used continuously and categorized. Linear and multinomial regression models adjusted for potential confounding factors were performed to assess the relationship between adherence to PHDI and outcomes. An inverse association was observed between adherence to PHDI and obesity indicators. Individuals with high adherence to the PHDI had lower BMI (ß-0.50 95% CI-0.73:-0.27) and WC (ß-1.70 95% CI-2.28:-1.12) values. They were also 24% less likely to be overweight (OR 0.76 95% CI 0.67:0.85) or obese (OR 0.76 95% CI 0.65:0.88), and they were 14% and 27% less likely to have increased WC (OR 0.86 95% CI 0.75:0.98) or substantially increased WC (OR 0.73 95% CI 0.64:0.83) than those with lower adherence. Our results showed that higher adherence to the PHDI may decrease obesity indicators.

Lack of association between proton pump inhibitor use and decline in cognitive performance in the ELSA-Brasil cohort.

OBJECTIVE: The study aims to investigate the longitudinal association of use and time of use of proton pump inhibitors (PPIs) with decreased performance in three cognitive tests. METHODS: Prospective cohort study included 7115 participants with mean age of 58.9 years at baseline (2008-2010) who participated in the second wave (2012-2014) of ELSA-Brasil (average interval between visits = 3.9 years (range: 1.7 to 6.0 years)). Cognitive performance was assessed by tests of memory, phonemic and semantic verbal fluency, and the trail making test, applied to both waves. Associations with the use and time of use of PPIs at baseline were investigated using linear models with mixed effects after adjusting for confounding factors. RESULTS: At baseline, 7.4% (529) of the participants used PPIs on a regular basis. After all adjustments, the interaction term use of PPI × age was not statistically significant for the cognitive tests evaluated, indicating that the use of PPI at baseline was not associated with a more accelerated decline in cognitive performance between waves. The interaction term PPI use × age was not statistically significant, in any of the categories of medication use time, any of the cognitive function tests evaluated, indicating that PPI use time is not associated with decrease in cognitive scores as the time interval between visits increases. CONCLUSION: In this cohort middle-aged and elderly adults, after average interval of 3.9 years (relatively short time to detect cognitive decline in a young cohort), the use and time of use of PPIs at the beginning of the study were not associated with a decline in cognitive performance in these tests between visits.

Anxiety, Depression, and Anger in Bruxism: A Cross-sectional Study among Adult Attendees of a Preventive Center.

The relationship between emotional symptom and bruxism is not well-established. We aimed to investigate sleeping bruxism and psychological factors. A cross-sectional study was performed in working-age adults attended in general outpatient service. The main outcome was the sleep bruxism diagnosed by dentist. Sociodemographic, clinical and psychological characteristics were evaluated according to sleep bruxism (yes/no). Scores of self-report scales of psychological symptoms (Beck Anxiety Inventory, Patient Health Questionnaire, and Dimensions of Anger Reactions) were individually subjected to factor analysis, through the extraction method of principal axis factoring. The associations between probable cases of sleep bruxism with dimensions of anxiety (somatic and cognitive), depression, and anger were estimated by linear regression models. Linear regression models (with ß coefficients and 95% CI) were adjusted for sociodemographic covariates. Among 351 respondents, 37.3% presented sleep bruxism. Of them, high frequencies of symptoms of anger (68.1%), moderate-severe anxiety (23.6%), and depression (17.9%) were observed. After adjustment, somatic-anxiety (ß: 0,136; CI95%: 0,028 to 0.276) was associated with sleep bruxism, but not cognitive-anxiety, depression or anger. The presence of sleeping bruxism should be routinely explored among adults, regarding its relationship with emotional symptoms.

Moderate coffee consumption is associated with lower risk of mortality in prior Acute Coronary Syndrome patients: a prospective analysis in the ERICO cohort.

This study examined the association between coffee consumption and all-cause mortality in patients with a prior acute myocardial infarction or unstable angina. Data were from the prospective study ERICO, totalising 928 patients with Acute Coronary Syndrome (ACS). During 4 years' follow-up, a total of 111 deaths occurred. Moderate coffee consumption (1-2 and 2-3 cups/day) was inversely associated with total mortality (HR 0.13, 95% CI: 0.06-0.29 and 0.22, 95% CI: 0.13-0.39, respectively). For patients with higher coffee consumption (>3 cups/day), there was a positive association with mortality (HR 2.12, 95% CI: 1.06-4.24). After stratification by smoking status, the analysis revealed lower risk of mortality in never and former smokers, drinking 1-2 and 2-3 cups/day. Among current smokers there was a positive association between >3 cups/day and mortality. The moderate consumption of coffee was associated with lower risk of all-cause mortality in patients with a prior ACS, particularly in non-smokers.

Public policies in headache disorders: needs and possibilities.

Although headaches have recognized impact, there are no public policies in Brazil addressing this problem. The Brazilian Headache Society and the Brazilian Association of Cluster Headache and Migraine promoted a summit to discuss Public Policy and Advocacy for headache disorders. Professionals from various segments, representing various sectors of society, gathered in April 2019 in Brasília, defining the most important points for achieving advances in public policies in headache in Brazil, such as: inclusion in the chronic diseases surveillance agenda; improving public understanding and access to diagnosis and treatment; teaching in colleges and medical residences, structuring care networks, intervention models, clinical protocols and legislation supporting public policies in headache.

Migraine and Arterial Stiffness in the Brazilian Longitudinal Study of Adult Health: ELSA-Brasil.

BACKGROUND: The mechanisms that underlie the link between migraine and cardiovascular diseases are not clear and arterial stiffness could play a role in that association. We analyzed the association between migraine and vascular stiffness measured by carotid-to-femoral pulse wave velocity (PWV-cf). METHODS: In a cross-sectional analysis of a well-defined population from the Longitudinal Study of Adult Health (ELSA-Brasil) with complete and validated information about migraine and aura according to the International Headache Society criteria, the association between arterial stiffness measured by PWV-cf was tested with multiple linear regression models [ß (95% CI)] comparing migraine without aura (MO) and migraine with aura (MA) to the reference group no-migraine (NM). Subsequent adjustments were made for mean arterial pressure, age, sex, education level, physical activity, alcohol use, diabetes mellitus, smoking, antihypertensive medication, body mass index, waist circumference, triglycerides, and LDL-c level to test the independence of the association between migraine status and pulse wave velocity. RESULTS: We studied 4,649 participants, 2,521 women (25.7% MO and 15% MA) and 2,128 men (11% MO and 4.3% MA). In NM, MO, and MA standard PWV-cf were 8.67 (±1.71) 8.11 (±1.31) and 8.01 (±1.47) m/s, respectively. Unadjusted PWV-cf differed between NM, MA, and MO (P < 0.001). After adjustment for mean arterial pressure PWV-cf in NM did not differ anymore from MA (P = 0.525) and MO (P = 0.121), respectively. Fully adjusted models also yielded nonsignificant coefficients ß (95% CI) -0.079 (-0.280; 0.122) and -0.162 (-0.391; 0.067) for MO and MA, respectively. CONCLUSION: In this large cohort of middle-aged adults, aortic PWV was not associated with migraine.
