Topic: Visual impairment (VI) and cognitive impairment (CIM) are prevalent age-related conditions that impose substantial burden on the society. Findings on the hypothesized bidirectional association of VI and CIM remains equivocal. Hence, we conducted a systematic review and meta-analysis to examine this bidirectional relationship.Clinical Relevance: Sixty percent risk of CIM has not been well elucidated in the literature. A bidirectional relationship between VI and CIM may support the development of strategies for early detection and management of risk factors for both conditions in older people.Methods: PubMed, Embase, and Cochrane Central registers were searched systematically for observational studies, published from inception until April 6, 2020, in adults 40 years of age or older reporting objectively measured VI and CIM assessment using clinically validated cognitive screening tests or diagnostic evaluation. Meta-analyses on cross-sectional and longitudinal associations between VI and CIM outcomes (any CIM assessed using screening tests and clinically diagnosed dementia) were examined. Random effect models were used to generate pooled odds ratios (ORs) and 95% confidence intervals (CIs). We also examined study quality, publication bias, and heterogeneity.Results: Forty studies were included (n ¼ 47 913 570). Meta-analyses confirmed that persons with VI were more likely to have CIM, with significantly higher odds of: (1) any CIM (cross-sectional: OR, 2.38 [95% CI, 1.84e3.07]; longitudinal: OR, 1.66 [95% CI, 1.46e1.89]) and (2) clinically diagnosed dementia (cross-sectional: OR, 2.43 [95% CI, 1.48e4.01]; longitudinal: OR, 2.09 [95% CI, 1.37e3.21]) compared with persons without VI. Significant heterogeneity was explained partially by differences in age, sex, and follow-up duration. Also, some evidence suggested that individuals with CIM, relative to cognitively intact persons, were more likely to have VI, with most articles (8/9 [89%]) reporting significantly positive associations; however, meta-analyses on this association could not be conducted because of insufficient data.Discussion: Overall, our work suggests that VI is a risk factor of CIM, although further work is needed to confirm the association of CIM as a risk factor for VI. Strategies for early detection and management of both conditions in older people may minimize individual clinical and public health consequences. Ophthalmology 2021;128:981-992 ª 2020 by the American Academy of Ophthalmology Supplemental material available at www.aaojournal.org.With 2 billion people estimated to be 60 years of age or older worldwide by 2050, 1 the number of individuals with cognitive impairment (CIM) also is expected to triple by 2050. 2 Presently, cognitive decline is the fifth leading cause of disability for the elderly 3 and imposes a significant physical, psychological, economic, and social burden on patients, caregivers, families, and society. 4,5 Treatment strategies for CIM or dementia are limited. 6 Therefore, identifying potentially modifiable risk fac...

Older adults with low educational or literacy levels should be targeted for screening programs in these populations.

Objective: To estimate the prevalence of frailty and evaluate the relationship with the social determinants of health in elderly residents in urban and rural areas of Colombia. Methods: The SABE (Health, Wellbeing, and Aging) Colombia project is a cross-sectional study, carried out in 2014-2015, involving 24,553 men and women aged 60 years and older who live in the community in Colombia. For this analysis, we used data from 4,474 participants included as a subsample with grip strength measurements. The frailty syndrome was diagnosed according to the Fried criteria (weakness, low speed, low physical activity, exhaustion, and weight loss). The independent variables were grouped as (a) biological and genetic flow, (b) lifestyle (adverse conditions in childhood) (c) social networks and community, and (d) socio-economic, cultural and environmental conditions. Multiple logistic and linear regression analyses were used to assess the prognostic value of frailty for the outcomes of interest. Results: The prevalence of frailty was 17.9%. The factors significantly associated with frailty were older age, being women, living in rural areas, having low education, a greater number of medical conditions, insufficient current income, childhood health problems and a poor economic situation in childhood. Conclusions: Our results support the need to include frailty prevention programs, to improve the socioeconomic health conditions of infants to avoid future development of frailty.

To explore the association between past sexual abuse and depression in elders living in Bogotá, Colombia, we used data from the SABE (Salud, Bienestar y Envejecimiento [Health, Well-being, and Aging]) Bogotá Study. Participants were 2000 community-dwelling adults aged 60 years and older in 2012. Sexual abuse was assessed by self-report. Depression was measured by the Geriatric Depression Scale. The weighted prevalence estimate was 2.6% for past sexual abuse and 23.4% for depression. Multivariate data analyses showed significantly higher odds of depression for past sexual abuse (odds ratio [OR] = 3.91, 95% confidence interval [CI]: 2.13-7.16). Other characteristics associated with depression were history of being displaced by violence (OR = 1.77, 95% CI: 1.30-2.40), low socioeconomic status, low education, poor self-rated health status, and poor self-rated memory. Thus, past sexual abuse and history of being displaced by violence were strongly associated with depression among Colombian elderly individuals.
