Background: Frailty in the elderly can be regarded as nonspecific vulnerability to adverse health outcomes, caused by multiple factors. The aim was to analyze the relationships between the frailty index, age and mortality in a two year follow up study of Mexican elderly. Methods: A frailty index was developed using 34 variables. To obtain the index, the mean of the total score for each individual was obtained. Survival analyses techniques were used to examine the risk ratios for the different levels of the frailty index. Kaplan-Meier estimates were obtained, adjusted for age and gender. Cox proportional hazards models were also built to obtain hazard ratio estimates. Results: A total of 4082 participants was analyzed. Participants had an average age of 73 years and 52.5% were women. On average, participants were followed-up for 710 days (standard deviation = 111 days) and 279 of them died. Mortality increased with the frailty index level, especially in those with levels between .21 to .65, reaching approximately 17% and 21%, respectively. Cox proportional hazards models showed that participants with frailty index levels associated to increased mortality (.21 and higher) represent 24.0% of those aged 65-69 years and 47.6% of those 85 and older. Conclusion: The frailty index shows the properties found in the other studies, it allows stratifying older Mexican into several groups different by the degree of the risk of mortality, and therefore the frailty index can be used in assessing health of elderly.

Background: The study of frailty is important to identify the additional needs of medical long-term care and prevent adverse outcomes in community dwelling older adults. This study aimed to determine the prevalence of frailty and its association with adverse outcomes in community dwelling older adults. Methods: A cross-sectional study was carried out from April to September 2014. The population sample was 1,252 older adults (≥60 years) who were beneficiaries of the Mexican Institute of Social Security (IMSS) in Mexico City. Data were derived from the database of the “Cohort of Obesity, Sarcopenia and Frailty of Older Mexican Adults” (COSFOMA). Operationalization of the phenotype of frailty was performed using the criteria of Fried et al (weight loss, self-report of exhaustion, low physical activity, slow gait, and weakness). Adverse outcomes studied were limitation in basic activities of daily living (ADLs), falls and admission to emergency services in the previous year, and low quality of life (WHOQOL-OLD). Results: Frailty was identified in 20.6% (n=258), pre-frailty in 57.6% (n=721), and not frail in 21.8% (n=273). The association between frailty and limitations in ADL was odds ratio (OR) =2.3 (95% confidence interval [CI] 1.7–3.2) and adjusted OR =1.7 (95% CI 1.2–2.4); falls OR =1.6 (95% CI 1.2–2.1) and adjusted OR =1.4 (95% CI 1.0–1.9); admission to emergency services OR =1.9 (95% CI 1.1–3.1) and adjusted OR =1.9 (95% CI 1.1–3.4); low quality of life OR =3.4 (95% CI 2.6–4.6) and adjusted OR =2.1 (95% CI 1.5–2.9). Conclusion: Approximately 2 out of 10 older adults demonstrate frailty. This is associated with limitations in ADL, falls, and admission to emergency rooms during the previous year as well as low quality of life.

Background: COVID-19 has had a disproportionate impact on older adults. Mexico’s population is younger, yet COVID-19’s impact on older adults is comparable to countries with older population structures. Here, we aim to identify health and structural determinants that increase susceptibility to COVID-19 in older Mexican adults beyond chronological aging. Methods: We analyzed confirmed COVID-19 cases in older adults using data from the General Directorate of Epidemiology of Mexican Ministry of Health. We modeled risk factors for increased COVID-19 severity and mortality, using mixed models to incorporate multilevel data concerning healthcare access and marginalization. We also evaluated structural factors and comorbidity profiles compared to chronological age for COVID-19 mortality risk prediction. Results: We analyzed 20 804 confirmed SARS-CoV-2 cases in adults aged 60 and older. Male sex, smoking, diabetes, and obesity were associated with pneumonia, hospitalization, and intensive care unit (ICU) admission in older adults, CKD and COPD were associated with hospitalization. High social lag indexes and access to private care were predictors of COVID-19 severity and mortality. Age was not a predictor of COVID-19 severity in individuals without comorbidities and combination of structural factors and comorbidities were better predictors of COVID-19 lethality and severity compared to chronological age alone. COVID-19 baseline lethality hazards were heterogeneously distributed across Mexican municipalities, particularly when comparing urban and rural areas. Conclusions: Structural factors and comorbidity explain excess risk for COVID-19 severity and mortality over chronological age in older Mexican adults. Clinical decision-making related to COVID-19 should focus away from chronological aging onto more a comprehensive geriatric care approach.

Purpose: The present study aims to explore characteristics associated with low perception of autonomy among community-dwelling older adults. Patients and methods: This original research was derived from a cross-sectional study based on the study COSFOMA with information from 1,252 (60 years and older) community-dwelling older adults whose data was obtained through a questionnaire that included sociodemographic characteristics, as well as different scales of geriatric assessment. The perception of autonomy was evaluated with the autonomy sub-scale of the Quality of Life Scale of Older Adults from the World Health Organization (World Health Organization Quality of Life of Older Adults, WHOQOL-OLD). Results: The mean (SD) age of the 1,252 community-dwelling older adults participating in the study was 68.5 (7.2) years. The average perception of autonomy was 65.3 (18.2) points out of 100. In the final logistic regression model, schooling <6 years (Odds Ratio, OR = 2.1, 95% Confidence Interval, CI = 1.5–2.9), low social support (OR = 1.6, 1.2–2.2), low spirituality (OR = 2.6, 95% CI = 1.9–3.4), presence of cognitive impairment (OR = 1.9, 95% CI = 1.4–2.5), anxiety (OR = 1.7, 95% CI = 1.2–2.5), and limitation in activities of daily living (ADL) (OR = 1.6, 95% CI = 1.1–2.2) were statistically associated with the presence of low autonomy in older adults. Conclusion: The perception of autonomy among community-dwelling older adults is moderate. Social support and spirituality, as well as cognitive impairment, anxiety, and limitations in ADL, play a significant role for degree of perceived autonomy in this population. Health professionals can use this information to promote participation in decision-making processes through programs that improve quality of life.

Objective: The objective of the current work was to determine the association between food insecurity and frailty in older adults, within the context of a country with accelerated ageing and nutritional problems.Design: Cross-sectional analysis of a representative nationwide survey on health and nutrition.Setting: Mexican nationwide survey.Subjects: A sample of 7108 adults aged 60 years or older living in communities, representative of Mexican older adults.Results: Multivariate regression and descriptive analyses of food insecurity and frailty were performed. From a total of 7108 adults aged 60 years or older, with a mean age of 70·7 years, most (54·7 %) were women. Food security categories were: 26·3 % had food security, 40·3 % had mild food insecurity, 20·5 % had moderate food insecurity and 12·9 % had severe food insecurity. Food insecurity categories were associated with frailty, with the severe category having the highest odds ratio of 2·41 (95 % CI 2·03, 2·86; P<0·001) after adjustment for confounding factors.Conclusions: According to our results, food insecurity is associated to frailty, which in turn is a condition that renders the older adult at a higher risk of developing adverse outcomes. Targeted food programmes for older adults with a high risk of having food insecurity or of being frail may improve health in this population group.

Background . Falls are a significant public health problem among older people worldwide. The aim was to perform a new systematic review and meta‐analysis to assess whether cataract surgery is effective in reducing the rate of falls in older persons. Methods . The systematic review was performed following the recommendations by the Cochrane Collaboration. Original papers were included with RCT or quasi‐experimental design, which described the effect on uni‐ or bilateral cataract surgery on the rate of falls among people aged 60 or older. Titles and abstracts were reviewed, full‐text versions were retrieved, and two independent examiners reviewed them to assess inclusion criteria. All relevant variables were synthesised in an evidence table. Random‐effects meta‐analyses were performed pooling the trials, and results were expressed as relative risk (RR) and 95% confidence intervals. Results . The initial search reported 99 potential abstracts, and 41 full‐text versions were examined. In the end, eight studies were included. Five included patients 65 years of age and older, two patients 55 years and older, and one included patients 50 years or older. Phacoemulsification and intraocular lens implant were performed in all studies. Two were RCT, and six were quasi‐experimental. Falls was the main outcome. The six quasi‐experimental studies reported that a reduction in the frequency of falls was observed (RR 0.68, 95% CI 0.48–0.96), although heterogeneity was significant ( I ² = 74%). Only one RCT reported risk reduction of 34% (RR 0.66, 95% CI 0.45–0.96). Conclusions . This meta‐analysis provides evidence that the first cataract surgery reduces the frequency of falls in older people with bilateral cataracts, but a second surgery does not have significant impact.
