Association between sleep problems and multimorbidity patterns in older adults.

Background: Sleep problems are frequent in older adults and are associated with chronic diseases. However, the association with multimorbidity patterns is still unknown. Considering the negative impacts that multimorbidity patterns can have on older adults' life, knowledge of this association can help in the screening and early identification of older adults with sleep problems.

Is waist circumference associated with fear of falling in community-dwelling older adults? A cross-sectional study.

Introduction: Fear of falling (FOF) is a prevalent condition among older adults and several variables have been pointed out as risk factors.

Objectives: To identify the cut-off point on waist circumference (WC), capable of discriminating between older adults with and without FOF, and to test the association between WC and FOF.

Methods: A cross-sectional observational study was carried out with older adults of both sexes from Balneário Arroio do Silva, Brazil.

Sex differences in dementia risk and risk factors: Individual-participant data analysis using 21 cohorts across six continents from the COSMIC consortium.

Introduction: Sex differences in dementia risk, and risk factor (RF) associations with dementia, remain uncertain across diverse ethno-regional groups.

Methods: A total of 29,850 participants (58% women) from 21 cohorts across six continents were included in an individual participant data meta-analysis. Sex-specific hazard ratios (HRs), and women-to-men ratio of hazard ratios (RHRs) for associations between RFs and all-cause dementia were derived from mixed-effect Cox models.

A nationwide study on pain manifestations and sleep problems in community-dwelling older adults: findings from ELSI-Brazil.

Purpose: Sleep problems are common and affect approximately 36-70% of older adults worldwide and can be associated with negative outcomes such as pain. There is believed to be a bidirectional relationship between sleep problems and pain, modulated by inflammation and stress. The objective was to investigate the association between self-reported sleep problems and pain manifestations.

Changes in access to water and incidence of waterborne diseases after the Vale dam collapse in Brumadinho (MG), Brazil.

Objective: To describe, within the Human Rights to Water and Sanitation (HRWS) framework, the access to water supply services and the incidence of waterborne diseases in the communities affected by the dam disaster in Brumadinho (MG), Brazil.

Methods: A quantitative and qualitative methodology was used, having as variables information on access to water supply services and waterborne diseases. The primary data were extracted from the "Brumadinho Health Project", using a sample stratum with 981 people interviewed, totaling 92.

End-of-life perspectives according to family caregivers of older adults with dementia: A qualitative study.

Background: Family caregivers are primarily responsible for the care of older adults with dementia, and the demands of this care increase as the end of life approaches. Experiencing the end of a family member's life can be stressful, and caregivers consider important to know how to identify when their loved one is approaching the end of life in order to prepare for this moment. Thus, as the family is primarily responsible for the older adult with dementia, it is essential to know the meanings of the end of life attributed by family caregivers.
