Based on a national representative sample of the population aged 50 years or older, this study aimed to estimate the prevalence of frailty among men and women, identify associated sociodemographic and health factors, and estimate the population attributable fraction. Data from the second wave (2019-2021) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) were used. Frailty was classified based on the number of positive items among unintentional weight loss, exhaustion, low level of physical activity, slow gait, and weakness.

This study aimed to estimate prevalence of loneliness among older Brazilian adults over the first seven months of the COVID-19 pandemic and to identify the predictors of loneliness trajectories. Pre-pandemic data derived from face-to-face interviews of participants of the 2019-2020 Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is a nationally representative study of community-dwelling individuals aged 50 years and over. Pandemic data were based on three rounds of telephone interviews among those participants, conducted from May to October 2020.

Toxoplasma gondii is a neuroinvasive parasite linked to cognitive decline that also presents a higher prevalence in schizophrenia. Here, we compared the cognition and symptom severity of IgG seropositive (TOXO+; n = 25) and seronegative (TOXO-; n = 35) patients who participated in a randomized controlled trial of digital cognitive training.

Methods: This is a cross-sectional study, part of the Brumadinho Health Project, developed in 2021, with a representative population-based sample of adults (18 years and over) residing in Brumadinho. A total of 2,805 adults with information on self-reported use of psychotropic drugs (antidepressants and anxiolytics-hypnotics/sedatives) in the last 15 days were included in the analysis.
Objective: To analyze the factors associated with paid work, after the dam failure, based on geographic strata, among men and women residing in Brumadinho, Minas Gerais.
Methods: Baseline data from participants of the Brumadinho Health Project, aged 18 years or older, obtained through a questionnaire, between July and November 2021 (n=2,783) were used. The dependent variable was paid work after the dam failure and the explanatory variables were geographic stratum, age, education, race/skin color, self-perception of health and employment relationship before the event.
Objective: In January 2019 a dam at the Córrego do Feijão mine suffered a catastrophic failure that killed 270 people and caused extensive damage. It is unknown how exposure to such a disaster might affect healthcare utilization.
Methods: We assessed survey data from the Brumadinho Health Project, a cohort study that includes people who were exposed to the dam failure and two comparison groups: people unexposed to mining or the disaster and people from a mining community, but not exposed to the disaster.
Objective: To present the methodological aspects of the Brumadinho Health Project and to describe the epidemiological profile of participants in the baseline cohort.
Methods: Prospective, population-based cohort study in a representative sample of residents (aged 12 and over) of Brumadinho, Minas Gerais, after a mining tailings dam failure. Information for the baseline was collected in 2021, two years after the mining tailings dam collapsed, including sociodemographic, health and service use aspects, among others.
This study aimed to investigate the association between social capital and functional disability, based on a longitudinal perspective, using data from the cohort of older adults from Bambuí, Minas Gerais State, Brazil. The baseline of this study was composed of all surviving and disability-free - up until the seventh year of follow-up (2004) - older adults who were followed up until 2011. The outcome variable was functional disability for basic activities of daily living (ADL) and instrumental activities of daily living (IADL), separately analyzed.

Validity of the AIMS norms were later reassessed using a logistic regression model that placed the AIMS items on an age scale.
Objectives: Our study examined the validity of the AIMS norms for Brazilian infants using the recommended method for calculating and comparing item locations.
The objective of this study was to evaluate whether healthy behaviours determine the adoption of individual protective measures to fight COVID-19. The data were obtained from the ELSI-COVID-19 initiative, a telephone survey conducted among participants in the Brazilian Longitudinal Study of Aging (ELSI-Brazil), which includes a national sample representative of the population aged 50 years or older. The outcomes evaluated were three protective measures (not having left home in the past week, wearing a mask when leaving home, and sanitizing hands when returning home), and the explanatory variables were health behaviours (smoking, alcohol consumption, consumption of fruits and vegetables, and physical activity).
