Asociación de dependencia con valoración nutricional, fragilidad y sarcopenia en el adultos mayores peruanos
Condori Fernández, Roxana Carla
En el Perú existen 4 millones 140 mil adultos mayores de 60 y más años de edad que representan el 12,7% de la población total al año 2020. Objetivo: asociar de dependencia con valoración nutricional, fragilidad y sarcopenia en los adultos mayores peruanos. Material y métodos: Estudio observacional transversal. Participaron en este estudio AM de ≥ 60 años, pertenecientes al Distrito de Miraflores, Perú. Se aplicaron encuestas para determinar valoración geriátrica integral, análisis de composición corporal y bioquímico. Resultados: Participaron 100 AM, de los cuales 67% eran del sexo femenino, el 29% de los participantes presento dependencia leve, ninguno con dependencia severa. El grupo de personas con dependencia muestra mayor puntaje en sarcopenia (p<0,001) y somnolencia diurna (p<0,001), por el contrario, comen menos alimentos poco saludables (p=0,047). Respecto a los alimentos y preparaciones saludables y no saludables, las principales diferencias se presentan que los sujetos con dependencia, la frecuencia de consumo de desayuno y el consumo de agua es menor al compararlos con el otro grupo que no tiene dependencia (p<0,001). En tanto se halló que, tener menos de 70 años y presentar ingesta de alimentos saludables, menor sarcopenia y menor insomnio se asocian a menor presencia de dependencia. Conclusiones: Los AM con dependencia en nuestro estudio se asocian con mayor edad, somnolencia diurna y sarcopenia, pero consumen menos alimentos no saludables que los AM que no presentan problemas de dependencia.

The deleterious consequences of collinearity in linear regression on the precision of estimators of regression coefficients and the interpretability of the fitted model are widely recognized. In this study, we compare several methodologies for assessing collinearity in linear models and explore the effect of outliers on collinearity. The robustness of collinearity measures (individual and overall) is validated through two detailed Monte Carlo simulation study which also considers the effect of outliers on collinearity indices. The methods are illustrated with two real-world agricultural and fish morphology l data sets to show potential applications. The results do not provide any evidence for an effect from outliers on collinearity identification using the collinearity indices (individual and overall). The FG and Fj collinearity indices more robust as both sample size and collinearity degree increase. The VIF (individual measure) had a better performance on the fitted model with a greater number of parameters. © 2024, Science Publications. All rights reserved.

Background: Previous research has suggested that manipulation and callousness are central to Dark Triad traits, but it has not identified which specific manifestations are expressed across various countries. Objective: This study aimed to identify the core and overlapping manifestations of Dark Triad traits across 10 countries. Methods: We used the Short Dark Triad (SD3) scale and assessed a sample of 8093 participants (59.7% women, M(age) = 32.68 years). For graphical representation, the spinglass algorithm was applied to understand the cluster distribution among Machiavellianism, psychopathy, and subclinical narcissism traits. Centrality indices were used to identify the most influential items, and the clique-percolation algorithm was employed to detect shared attributes among multiple Dark Triad items. Results: Straightforward SD3-21 items demonstrated better interpretability as aversive traits within the broader system. Items with higher centrality values were those related to short-term verbal manipulation from the psychopathy domain, clever manipulation, strategic revenge-seeking from Machiavellianism, and narcissistic motivations for connecting with significant individuals. The most predicted items were linked to planned revenge, using information against others from Machiavellianism, short-term psychopathic verbal manipulation, and narcissistic belief of specialness based on external validation. Items like short-term verbal manipulation had overlaps with both psychopathy and narcissism clusters, while clever manipulation overlapped with Machiavellianism and psychopathy. Conclusion: This cross-cultural study highlights the central role of verbal manipulation within the Dark Triad traits, along with identifying overlapping items among traits measured using straightforward SD3 scale items. In line with our findings, future research that incorporates a wide range of cultural contexts is encouraged to establish the consistency of these findings with the SD3 Scale or alternative measures. © 2024 Ramos-Vera et al.

Background: University students often experience significant changes in their eating habits, which can increase the risk of developing eating disorders (ED). This situation calls for the creation of brief assessment tools to identify college students who may be most at risk. The aim of the study was to determine the psychometric properties of the Eating Attitudes Test-8 (EAT-8) in a Peruvian university population; additionally, the possible differences in the scores of the instrument according to sociodemographic variables, such as gender and age, were examined. Methods: A psychometric study was conducted on 610 participants (M = 24.3, SD = 2.16, and 61.5% female), aged 19 to 31 years, belonging to four universities of different professional careers. Results: The unidimensional eight-item model was found to have fit indices that confirm acceptable factorial validity (X2/df = 3.23, CFI = 0.984, TLI = 0.977, RMSEA = 0.061, SRMR = 0.049) and an internal consistency of 0.833 for the Cronbach's alpha coefficient and 0.838 for the McDonald's omega coefficient. In addition, the EAT-8 was reported to be invariant according to gender and age; likewise, there were no significant differences in the age and gender categories. Conclusion: The EAT-8 has solid psychometric properties, including validity, reliability, and invariance, in the Peruvian university population, which supports its ability to assess the risk of developing ED in this specific group.
