Objectively measured far vision impairment and sarcopenia among adults aged ≥ 65 years from six low- and middle-income countries
Background:\ud \ud There are currently no studies on visual impairment and sarcopenia. We investigated the cross-sectional association between objectively measured far vision impairment and sarcopenia in a nationally representative sample of older adults aged 65 years and over from six low- and middle-income countries (LMICs).\ud \ud Methods:\ud \ud Cross-sectional, community-based data from the study on global ageing and adult health (SAGE) were analyzed. Far vision acuity was measured using the tumbling E LogMAR chart and classified as: no vision impairment (6/12 or better); mild vision impairment (6/18 or better but worse than 6/12); moderate vision impairment (6/60 or better but worse t…
Active Travel and Mild Cognitive Impairment among Older Adults from Low- and Middle-Income Countries
Active travel may be an easily achievable form of physical activity for older people especially in low- and middle-income countries (LMICs), but there are currently no studies on how this form of physical activity is associated with a preclinical state of dementia known as mild cognitive impairment (MCI). Therefore, we aimed to investigate the association between active travel and MCI among adults aged ≥50 years from six LMICs. Cross-sectional, community-based data from the World Health Organization’s Study on Global Ageing and Adult Health were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer’s Association criteria. Active travel (minutes/week) was as…
Social isolation and physical activity mediate associations between free bus travel and wellbeing among older adults in England
Background: Aims of this study were: (i) to examine relationships between free bus travel and wellbeing, and (ii) to assess the extent to which these associations can be explained by two key potential mediators: social isolation and physical activity. Methods: Data were from the English Longitudinal Study of Ageing (n = 5861). Linear regression models tested associations between (i) concessionary bus pass (CBP) ownership and (ii) frequency of CBP use and three measures of wellbeing (quality of life, life satisfaction, depressive symptoms), adjusting for age, sex, marital status, socioeconomic status and limiting long-standing illness. Mediation analyses tested the role of (i) social isolati…
Associations between cataract and multimorbidity: a cross-sectional study of 23,089 adults from Spain
Background: Little is known about the association between cataract and multimorbidity. Therefore, the aim of the present study was to examine the relationship between cataract and chronic conditions and multimorbidity in a large representative sample of Spanish adults. Methods: This study used data from the Spanish National Health Survey 2017, a cross-sectional sample of 23,089 adults aged ≥15 years from Spain [54.1% female; mean (standard deviation) age 53.4 (18.9) years]. Cataract and 30 other physical and mental chronic conditions were self-reported. Multimorbidity was defined as the presence of at least two physical and/or mental chronic conditions (excluding cataract). Control variable…
The Association Between Physical Activity and Cataracts Among 17,777 People Aged 15-69 Years Residing in Spain.
Purpose: The aim of the present study was to assess the association between levels of physical activity (PA) and the presence of cataracts in people aged 15–69 years residing in Spain. Methods: Cross-sectional data from the Spanish National Health Survey 2017 were analysed (n = 17,777 ≥ 15 years; 52% females; self-weighting sample). The International Physical Activity Questionnaire (IPAQ) short form was used to measure PA. Total PA MET-minutes/week were calculated, and participants were divided into two categories: 1) Less than 600 MET-minutes/week. 2) At least 600 MET-minutes/week, equivalent to meeting current PA recommendations. Cataracts were self-reported in response to the question “H…
Eye disease and mortality, cognition, disease, and modifiable risk factors: an umbrella review of meta-analyses of observational studies
Globally, 2.2 billion people live with some form of vision impairment and/or eye disease. To date, most systematic reviews examining associations have focused on a single eye disease and there is no systematic evaluation of the relationships between eye diseases and diverse physical and mental health outcomes. Moreover, the strength and reliability of the literature is unclear. We performed an umbrella review of observational studies with meta analyses for any physical and/or mental comorbidities associated with eye disease. For each association, random-effects summary effect size, heterogeneity, small-study effect, excess significance bias and 95% prediction intervals were calculated, and …
The Association Between Objectively Measured Vision Impairment and Self-Reported Physical Activity Among 34,129 Adults Aged ≥50 Years in Six Low- and Middle-Income Countries.
The authors investigated the association between vision impairment and physical activity among older adults from low- and middle-income countries. Visual acuity was measured using the tumbling ElogMAR chart, and vision impairment was defined as visual acuity worse than 6/18 (0.48 logMAR) in the better seeing eye. Physical activity was assessed by the Global Physical Activity Questionnaire. Multivariable logistic regression and meta-analysis were conducted to assess associations. The sample included 34,129 individuals aged 50–114 years (mean [SD] age 62.4 [16.0] years; 47.9% male). After adjustment for confounders, near vision impairment was not significantly associated with low physical act…
