Dietary patterns derived from three diet quality indices and associated factors: findings from the baseline of ELSA-Brasil.

The aim of this study was to describe dietary patterns using three diet quality indices and the associated factors among 15,081 participants from the baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Dietary intake was assessed through a food frequency questionnaire. Three diet quality indices were applied: the Planetary Health Diet Index (PHDI), the Cardiovascular Health Diet Index (CHDI), and the Healthy Eating Index-2015 (HEI-2015).

Physical Activity and Survival After an Acute Coronary Syndrome: Data From the ERICO Study.

Background: Due to enhancements in health care, the number of individuals who survive an acute coronary syndrome (ACS) event is rising. In this population, the impact of physical activity on long-term survival is still a matter of debate. We aimed to analyze the association between the level of physical activity during the first 4 years of follow-up and survival.

Association of adiposity evaluated by anthropometric and bioelectrical impedance analysis measures with cognitive performance in the ELSA-Brasil study.

Background: While midlife obesity is linked to cognitive decline, this association is inconsistent in older adults, possibly due to the limitations of body mass index (BMI) in accurately assessing adiposity at older ages. Most studies focused on White or Asian populations, did not include other adiposity measures besides BMI, adjusted the analyses for mediators, and did not investigate potential subgroup-specific associations. We compared the associations of adiposity measured by anthropometrical and bioelectrical impedance analysis (BIA) with cognitive performance in a diverse population, examining modifications by age, sex, and race, and investigating the mediating effects of obesity-related comorbidities.

Non-linear associations of serum lipid levels with cognitive decline: Findings from the ELSA-Brasil cohort.

Background And Aims: Elevated low-density lipoprotein-cholesterol (LDL-C) is a modifiable risk factor for dementia, but evidence on other lipids is inconsistent, particularly in studies from low and middle-income countries. This study aimed to assess the association between lipid levels and cognitive decline in the ELSA-Brasil cohort.

Methods: In this prospective study, baseline serum lipid profile [total cholesterol (TC), LDL-C, high-density lipoprotein-cholesterol (HDL-C), triglycerides, and non-high-density lipoprotein-cholesterol (Non-HDL-C)] was analyzed.

Prospective association between the Cardiovascular Health Diet Index and subclinical atherosclerosis: the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort study.

The Cardiovascular Health Diet Index (CHDI) is a diet quality score based on the dietary guidelines of the American Heart Association for cardiovascular health but with some adaptations, such as red meat, dairy products, beans and ultra-processed foods in its components. The CHDI has shown good relative validity parameters; however, its association with health outcomes is still unclear. Thus, our aim was to investigate the association between the CHDI score with subclinical atherosclerosis.

Religion and sociodemographic characteristics at baseline of the Brazilian Longitudinal Study of Adult Health study.

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.

Dietary acid load and the risk of events of mortality and kidney replacement therapy in people with chronic kidney disease: the Progredir Cohort Study.

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.

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.

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.

Recommender System Based on Collaborative Filtering for Personalized Dietary Advice: A Cross-Sectional Analysis of the ELSA-Brasil Study.

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.

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.

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.

The association between salt intake and blood pressure is mediated by body mass index but modified by hypertension: The ELSA-Brasil study.

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).

Biomarkers of Fruit Intake Using a Targeted Metabolomics Approach: an Observational Cross-Sectional Analysis of the ELSA-Brasil Study.

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.
