Pain symptoms and physical performance in older adults: cross-sectional findings from the International Mobility in Aging Study (IMIAS).

Purpose: To analyze the associations between pain and physical performance in different aging contexts.

Methods: Data from 1725 older adults from Canada, Brazil, Colombia, and Albania from the 2014 wave of the IMIAS were used to assess the associations between Back Pain (BP) or Lower Limb Pain (LLP) and physical performance by the Short Physical Performance Battery (SPPB). Three binary logistic regression models adjusted for sex, age, study site, education, income sufficiency, BMI, depressive symptoms, and chronic conditions were used to estimate the associations between LLP or BP and SPPB.

Allostatic load and physical performance in older adults: Findings from the International Mobility in Aging Study (IMIAS).

Objective: This study aimed to evaluate the association between Allostatic Load (AL) and physical performance scores in older adults from four cities in North and South America.

Methods: In this cross-sectional study, data from 1101 volunteers from three countries (Canada, Brazil, and Colombia) from the International Mobility in Aging Study (IMIAS) were used to evaluate the association between AL index and Short Physical Performance Battery (SPPB) scores. Three multiple linear regression models adjusted by age, Socioeconomic Status (SES), chronic conditions, depression symptoms, and Leganés Cognitive Test (LCT) were developed to estimate the independent association between SPPB and AL.

Effectiveness of an adapted diving mask (Owner mask) for non-invasive ventilation in the COVID-19 pandemic scenario: study protocol for a randomized clinical trial.

Background: Non-invasive ventilation (NIV) is indicated to avoid orotracheal intubation (OTI) to reduce hospital stay and mortality. Patients infected by SARS-CoV2 can progress to respiratory failure (RF); however, in the initial phase, they can be submitted to oxygen therapy and NIV. Such resources can produce aerosol and can cause a high risk of contagion to health professionals.

Validity and reliability of the Brazilian activities-specific balance confidence scale and determinants of balance confidence in community-dwelling older adults.

: The Activities-specific Balance Confidence scale is the most used tool to quantify balance confidence, a psychological factor related to balance impairment among older adults. : To investigate the validity and reliability of the original and short versions of the Brazilian Activities-specific Balance Confidence scales, to determine cutoff points for balance impairments and to identify the determinants of balance confidence of community-dwelling older adults.: The validity of both versions of the scales was verified by correlating its results with postural balance, fear of falling and mobility (n = 105).

Meeting Physical Activity Guidelines by Walking in Older Adults From Three Middle-Income Countries: A Cross-Sectional Analysis From the International Mobility in Aging Study.

Physical activity (PA) among older adults is understudied in middle-income countries. The authors examined the associations of factors across levels of the social ecological model (individual, interpersonal, organizational, and community) with older adults meeting guidelines of 150 min of moderate- to vigorous-intensity PA per week through walking in three middle-income countries: Albania (n = 387), Colombia (n = 404), and Brazil (n = 402). Using 2012 International Mobility in Aging Study data, multivariate logistic regression models identified the following significant associations with meeting PA guidelines through walking (a) individual level: depression (odds ratio [OR] = 0.

Clinically relevant weakness in diverse populations of older adults participating in the International Mobility in Aging Study.

The aims of this study were to compare cut points for weakness proposed by Foundation for the National Institutes of Health (FNIH) Sarcopenia Project with cut points estimated with our own data; to assess the prevalence of clinically relevant handgrip strength (HGS) weakness according to published criteria across distinct populations of older adults; to estimate the ability of HGS weakness to identify slowness. This is a cross-sectional analysis of International Mobility in Aging Study (IMIAS) involving 1935 community-dwelling older adults, between 65 and 74 years, who completed HGS and gait speed assessment. We used baseline data from Tirana (Albania), Natal (Brazil), Manizales (Colombia), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada).
