ABSTRACT
OBJECTIVE: We aimed to investigate the association between gait speed and cognitive status in outpatient older adults from a resource-limited setting in Peru. METHODS: We performed a cross-sectional study including older adults aged ≥60 years attending a geriatrics outpatient clinic between July 2017 and February 2020. Gait speed was measured over a 10-meters distance without considering the first and last meter traveled. Cognitive status was assessed through the Short Portable Mental Status Questionnaire (SPMSQ) and the Mini-Mental State Examination (MMSE). We used a multivariate binomial logistic regression to conduct both an epidemiological and fully adjusted models. RESULTS: We included 519 older adults (mean age: 75 years; IQR = 10), of whom 95 (18.3%) and 151 (31.5%) were cognitively impaired according to the SPMSQ and MMSE, respectively. Gait speed was slower among patients with poorer cognitive status as assessed by both tools (p < 0.001). Malnutrition (PR: 1.74; CI: 1.45-2.08) and functional dependency (PR: 4.35; CI: 2.68-7.08) were associated with a greater prevalence of cognitive impairment according to the SPMSQ, whereas a faster gait speed (PR: 0.27, CI: 0.14-0.52) and longer years of education (PR: 0.83, CI: 0.77-0.88) were associated with a less prevalence. CONCLUSIONS: Slower gait speed was associated with poorer cognitive status in outpatient older adults. Gait speed may be a complementary tool in the cognitive assessment of older adults from resource-limited settings.

This study aimed to describe the perception about vaccines and the level of knowledge, attitudes and practices towards COVID-19 in older adults from a hospital in Lima, Peru. Descriptive and cross-sectional study carried out from March to November 2021. An instrument was adapted and validated to measure the level of knowledge, attitudes and practices; the perception about vaccines was evaluated with an exploratory questionnaire. Eighty-three older adults were surveyed, the mean age was 74.0 years and 62.7% were women. Most of the participants knew the cause and symptoms, and 50.6% believed that it could be transmitted by contaminated food. Additionally, 61.7% used traditional medicine to prevent it, and 65.4% considered that the level of social awareness was insufficient; 91.5% were vaccinated against COVID-19, and 65.4% considered these vaccines to be safe. In conclusion, most older adults showed a high level of knowledge, attitudes and practices and a positive perception about the vaccine against COVID-19.
El objetivo fue describir la percepción sobre las vacunas y el nivel de conocimientos, actitudes y prácticas hacia la COVID-19 en adultos mayores que acuden a un hospital en Lima, Perú. Estudio descriptivo y transversal de marzo a noviembre del 2021. Se adaptó y validó un instrumento para medir el nivel de conocimientos, actitudes y prácticas, y se evaluó la percepción sobre vacunas con un cuestionario exploratorio. Se encuestaron a 83 adultos mayores, la media de edad fue 74,0 años y el 62,7% fueron mujeres. La mayoría conoce la causa y síntomas, y el 50,6% cree que puede transmitirse por alimentos contaminados. El 61,7% usa medicina tradicional para prevenirla, y el 65,4% considera insuficiente el nivel de conciencia social. El 91,5% se vacunó contra la COVID-19, y el 65,4% considera que estas vacunas son seguras. En conclusión, la mayoría de los adultos mayores presenta un alto nivel de conocimientos, actitudes y prácticas y una percepción positiva sobre la vacuna contra la COVID-19.

Objectives: We aimed to investigate the frequency of probable sarcopenia and to compare the performance of SARC-F and SARC-CalF for detecting this condition in outpatient older adults from a low-resource setting. Methods: We conducted a retrospective, cross-sectional study in outpatient older adults aged ≥60 years attending a hospital in Peru, between August 2019 and February 2020. Probable sarcopenia was defined as low handgrip strength (<27 kg in men and <16 in women). We used SARC-F and SARC-CalF with their standard cut-off points (≥4 and ≥11, respectively). Low calf circumference was defined as ≤33 cm in women and ≤34 cm in men. We performed sensitivity and specificity analyses. Results: We included 206 older adults, 102 (49.5%) aged ≥75 years old and 140 (67.9%) females. Probable sarcopenia was present in 36.40% of the participants. SARC-F ≥4 was observed in 29.61% and SARC-CalF ≥11 in 41.26% of the population. SARC-F≥4 showed 41.33% sensitivity and 77.10% specificity, whereas SARC-Calf ≥11 had 50.67% sensitivity and 64.12% specificity. Conclusion: We found that one out of three of the population had probable sarcopenia. SARC-Calf showed superior but still low sensitivity than SARC-F, while both had moderate specificity and thus may be useful for ruling out the disease in clinical practice.
