Monitoring sarcopenia with wearable devices: a systematic review protocol.

INTRODUCTION: Sarcopenia is a highly prevalent muscle dysfunction among older adults and is associated with adverse events. The periodic monitoring enables an early screening of patients at risk and control of the progression of muscle impairment. Wearable devices have been used as clinical support for sarcopenia detection. Therefore, this review aims to identify how wearable devices have been used to screen sarcopenia. METHODS AND ANALYSES: Searches will be conducted from August 2023 on PubMed, CINHAL, Embase, Web of Science and SciELO databases. We will include cross-sectional and/or baseline data from prospective studies reporting the use of wearable devices to investigate sarcopenia. Studies that discuss only the development of algorithms or applications for the assessment of sarcopenia or unavailable full texts will be excluded. The main reviewer will conduct the initial search and exclusion of duplicates, while two independent reviewers will select studies, extract data and assess the methodological quality using the Appraisal tool for Cross-sectional Studies. ETHICS AND DISSEMINATION: No previous ethical approval is required for this review. The findings of this review will be submitted to a scientific journal and disclosed at international scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42022356040.

Does body image perception relate to quality of life in middle-aged women?

OBJECTIVE: In Brazil, information about the influence of body image on the various life domains of women in menopausal transition is scarce. Thus, the objective of the study was to analyze the relationship between body image and quality of life in middle-aged Brazilian women. METHODS: This was a cross-sectional study of 250 women between 40 and 65 years old, living in Parnamirim/RN, Brazil, who were evaluated in relation to body image and quality of life. For body image, women were classified as: dissatisfied due to low weight, satisfied (with their body weight) and dissatisfied due to being overweight. Quality of life was assessed through a questionnaire in which higher values indicate higher quality of life. Multiple linear regression was performed to analyze the relationship between body image and quality of life, adjusted for covariates that presented p<0.20 in the bivariate analysis. RESULTS: The average age was 52.1 (± 5.6) years, 82% of the women reported being dissatisfied due to being overweight, and 4.4% were dissatisfied due to having low weight. After multiple linear regression analyzes, body image remained associated with health (p<0.001), emotional (p = 0.016), and sexual (p = 0.048) domains of quality of life, as well as total score of the questionnaire (p<0.001). CONCLUSION: Women who reported being dissatisfied with their body image due to having low weight or overweight had worse quality of life in comparison to those who were satisfied (with their body weight).

[Impact of cognitive deficit on survival among elderly residents in the community]. / Impacto del déficit cognitivo en la supervivencia de ancianos residentes en la comunidad.

OBJECTIVE: To analyze cognitive deficit as a risk factor for death in elderly residents in the community and its relationship with variables related to sociodemographic factors, physical health, and functional capacity. MATERIAL AND METHODS: A prospective study was carried out in the city of Santa Cruz, Brazil, in 310 randomly selected elderly individuals who were followed-up for 53 months. Predictive factors were sociodemographic and neuropsychiatric variables, physical health, and functional capacity. The statistical methods used were bivariate analysis (survival analysis), and Cox regression (multivariate analysis) with respective hazard ratios (HR). A value of P<.05 was considered statistically significant and 95% confidence intervals (CI) were calculated. RESULTS: A total of 60 (20.5%) elderly residents died during the study. The main cause of death was cardiovascular disease. The mean time until death was approximately 24.8 months. The main risk factors identified in Cox analysis were cognitive deficit (HR=4.22), stroke (HR=3.08) and dependency for basic activities of daily living (HR=3.55). CONCLUSIONS: Cognitive deficit is an independent risk factor for death. The results of the present study could be useful in formulating future health policies aiming to reduce mortality in the elderly.

Objetivo: analizar el déficit cognitivo como factor de riesgo para la defunción en ancianos residentes en la comunidad y su relación con variables sociodemográficas, de salud física y capacidad funcional. Material y métodos: hemos realizado un estudio prospectivo en la ciudad de Santa Cruz, Brasil, con 310 ancianos, seleccionados de forma aleatoria, que fueron seguidos durante 53 meses. Las variables predictoras fueron: sociodemográficas, de salud física, neuropsíquicas y de capacidad funcional. El tratamiento estadístico se efectuó por medio de un análisis bivariado (análisis de supervivencia) y regresión de Cox (análisis multivariado) con las respectivas hazard ratios (HR), considerando p < 0,05 y un intervalo de confianza (IC) del 95%. Resultados: un total de 60 (20,5%) ancianos murieron durante el período de seguimiento; la causa principal de la defunción fueron las enfermedades cardiovasculares. El tiempo medio hasta el fallecimiento fue de aproximadamente 24,8 meses y los principales factores de riesgo identificados en el análisis de Cox fueron: la dependencia para realizar actividades básicas de la vida diaria (odds ratio [OR] = 3,55) y el accidente cerebrovascular (HR = 3,08), además del déficit cognitivo (HR = 4,22). Conclusiones: el déficit cognitivo constituye un factor de riesgo de defunción. Consideramos que los resultados del presente estudio podrán utilizarse en el futuro para la formulación de políticas de salud y contribuir a reducir la mortalidad en los ancianos
