Item type:Publicación, Dietary practices and nutritional status of children served in a social program for surrogate mothers in Colombia(2023-02-06); ; ; BACKGROUND: Dietary practices are acquired in the family context and in turn can affect the health of family members, especially the nutritional status of children. The objective of this study was to determine the relationship between nutritional status and feeding practices in children from foster families served by the SOS Children's Villages program in Cartagena, Colombia. METHODS: The study had a cross-sectional design. Through a non-probabilistic purposive sampling, 139 children from 0 to 5 years of age from the SOS Children's Villages Cartagena program were involved. The sociodemographic background of the participants was recorded and the nutritional status of the children was evaluated through anthropometric and biochemical measurements. Dietary practices were measured by means of a standardized questionnaire. Analyses were performed with Poisson regression models with robust variance. These regression models provided prevalence ratios (PR) with their respective 95% confidence intervals (95%CI). RESULTS: Among dietary practices, it was observed that most families eat together at home (63.3%), watch television when they eat (55.4%), and have dietary norms (80.6%). Consumption of plant foods was predominantly high, especially vegetables (86.3%), fruits (92.1%), cereals (84.9%), root vegetables, and bananas (93.5%). Consumption < 4 times/week of soft drinks and industrialized juices increases 14.3 times the probability of low weight-for-height in the study population compared to the group that does not consume them. On the other hand, watching television while eating (PR: 2.82, 95%CI 1.32-4.69) and consumption of sweet snacks (PR: 2.24, 95%CI 1.03-4.87) increased the probability of low height-for-age; while having eaten norms at home decreased the probability of low height-for-age in the study population by 50%. CONCLUSION: It is necessary to develop and implement interventions such as preventive measures and early diagnosis of inappropriate feeding behaviors to ensure adequate nutritional status among children under 5 years of age.Citas (OpenAlex): 6metric-badges.view 7 - Algunas métricas están bloqueadas por suconfiguración de consentimiento

Item type:Publicación, Association and diagnostic value of a novel uric acid index to cardiovascular risk(2021-07-15); ; Gutierrez-Ajalcriña, RosmeryCardiovascular diseases (CVD) are the leading cause of death and disability worldwide. The aim of this study was to assess the association and diagnostic value of a novel uric acid index (UA index) to cardiovascular risk (CVR). and Methods: An analytical cross-sectional study was performed. We analyzed data from the Plan for Prevention and Surveillance of Communicable and Non-Communicable Diseases at the Hospital de Huaycan, Peru. The QRISK model was used to measure the CVR. Stepwise regression models were performed to determine significant factors to predict CVR and formulate the UA index, then the association of UA index and high CVR was evaluated by Poisson regression models, and the diagnostic accuracy was verified through ROC curves. In total 291 participants (206 women and 85 men) were analyzed. The correlation between UA index to CVR was stronger (R2:0.31, p < 0.001) than uric acid (UA) alone (R2:0.19, p < 0.001), and the contribution of UA was stronger than triglycerides or glucose in the stepwise regression model. In the Poisson models, the UA index adjusted model (PRa: 1.58, CI95% 1.11–2.24) presented significant independent association to CVR. The diagnostic accuracy was similar in men (cut-off: 10.8, AUC:0.81; 0.75–0.87) and women (cut-off: 10.0; AUC: 0.77, 0.71–0.84). UA index presented a good diagnostic accuracy and independent significant association to high CVR in adults from Peru. This marker can be used to assess CVR and follow therapeutic progress in primary health care.Citas (OpenAlex): 4metric-badges.view 7 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Validity and Reliability of a Brief Scale of Intention to Vaccinate Against COVID-19 in a Peruvian SampleObjective: This study aimed to analyze the psychometric properties of a brief scale measuring intention to vaccinate against COVID-19 in a Peruvian sample in the context of the current pandemic. Methods: A cross-sectional and instrumental study was carried out. A total of 547 Peruvian citizens selected through non-probability convenience sampling participated. Considering existing theories of vaccination hesitancy, 12 items were proposed that evaluate the intention to vaccinate against COVID-19 and the internal structure was evaluated through exploratory and confirmatory factor analysis. Reliability was analyzed with the ordinal alpha coefficient. Results: The exploratory factor analysis yielded a structure of 2 oblique factors that explain 69% of the total variance and the items saturated between 0.52 and 0.97. The confirmatory factor analysis showed that, of 4 models analyzed, the fourth model that was composed of 6 items presented optimal indices of goodness-of-fit ( X 2 = 11.089, P = .197, CFI = 0.999, TLI = 0.999, RMSEA = 0.034 [IC 90%, 0.000-0.077], SRMR = 0.016). Reliability analysis through the ordinal alpha coefficient yielded that the brief scale of intention to vaccinate against COVID-19 has adequate internal consistency (α = .91). Conclusions: The brief scale of intention to vaccinate against COVID-19 presents adequate psychometric properties that demonstrate validity and reliability and can be used in future research and clinical practice.Citas (OpenAlex): 3metric-badges.view 6 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Psychometric evaluation and invariance of the Spanish version of the Block Fat Screener (BFS-E) in university studentsIntroduction: University students constantly face a number of health challenges related to an unhealthy diet, characterized by a high intake of saturated fats. Objective: This study aimed to analyze the psychometric properties of the Spanish version of the Block Fat Screener (BFS-E) food frequency questionnaire in a university population. Methods: An observational analytical study of instrumental type was carried out in 5608 Peruvian university students. Based on the Block Fat Screener questionnaire, a back-translation and cultural adaptation process was carried out. The validity of the questionnaire was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), hypothesizing a unidimensional structure. For the determination of reliability, the alpha coefficients were considered; likewise, the ω and H coefficients were used to evaluate the construct. The model explained 63% of the cumulative variance. Results: The CFA confirmed the unidimensionality of the 16-item questionnaire with appropriate goodness-of-fit indicators; therefore, which model of the Peruvian version adequately fits the observed data. The values of the reliability coefficients were higher than 0.90, with ordinal α = 0.94, ω = 0.94, and H = 0.95. Conclusion: The Spanish version of the Block Fat Screener food frequency questionnaire presents adequate psychometric properties and is therefore a valid scale to quickly measure fat intake in university students in a Latin American context.Citas (OpenAlex): 6metric-badges.view 4 - Algunas métricas están bloqueadas por suconfiguración de consentimiento

Item type:Publicación, Burnout, Professional Self-Efficacy, and Life Satisfaction as Predictors of Job Performance in Health Care Workers: The Mediating Role of Work Engagement(2022-01-01); Background: It is essential to identify the factors that influence the work performance of health professionals working in health care facilities, especially in the context of the COVID-19 pandemic, since these factors have an impact on the quality of medical care provided to the population. Objective: This study aimed to analyze the mediating role of work engagement in the relationship between job burnout, professional self-efficacy, life satisfaction, and job performance in Peruvian health care workers. Methods: Cross-sectional explanatory study, with the voluntary participation of 508 health professionals (physicians and nurses) of both sexes (70.7% women, 29.3% men), and from different health facilities in the city of Lima. All participants were administered the Single Burnout Item questionnaire, the Professional Self-Efficacy Scale (AU-10), the Satisfaction with Life Scale (SWL), the Individual Work Performance Questionnaire (IWPQ), and the Utrecht Work Engagement Scale (UWES-9). Structural Equation Modeling (SEM) was used for data analysis. Results: In the SEM analysis, it was found that for the mediation model the incremental goodness-of-fit indices were significant (χ 2 = 2292.313, gl = 659, P < .001, χ 2 /gl = 2.788). Career self-efficacy (β = .557, P < .001) and life satisfaction (β = .289, P < .001) were positive predictors of work engagement. While burnout was a negative predictor (β = .878, P < .001). The consistent mediation of work engagement of professional self-efficacy, life satisfaction, and burnout had a positive predictor effect on job performance (β = .878, P < .001). Conclusion: Research provides evidence that professional self-efficacy, life satisfaction, and burnout could influence job performance through work engagement.Citas (OpenAlex): 154metric-badges.view 5 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Predictores de la somnolencia, satisfacción con los estudios y el cansancio emocional en estudiantes con altas capacidades intelectuales durante la pandemia COVID-19Introducción. Los cambios repentinos en la modalidad educativa escolar a causa de la pandemia COVID-19 y el aislamiento social han afectado el estilo de vida, salud mental y emocional, y la percepción de su formación académica en los estudiantes con altas capacidades intelectuales. El objetivo de este estudio fue analizar las variables predictoras de la somnolencia, satisfacción con los estudios y cansancio emocional en estudiantes con altas capacidades intelectuales durante la pandemia COVID-19. Método. Este estudio involucró a 409 estudiantes de tercero a quinto grado de secundaria con altas capacidades intelectuales y que reciben una educación especial gratuita asociada al talento y alto rendimiento (COAR). Las edades oscilaron entre 14 y 17 años (M = 15.26, DE = .89). Se utilizó la Escala Breve de Satisfacción con los Estudios (EBSE), Escala de Cansancio Emocional (ECE), Escala de Hábitos de Alimentación y Actividad Física (EHAAF), Índice de Pittsburgh, Generalized Anxiety Disorder Scale-2 (GAD-2) y la Escala Corta de Somnolencia de Epworth (ESE). Se calcularon estadísticos descriptivos y se evaluó la normalidad de las variables. Además, se analizó un modelo predictivo en base a los índices de bondad de ajuste usando modelos de ecuaciones estructurales. Los análisis se realizaron a través de los programas estadisticos SPSS 24.0 y Amos 24.0. Resultados. El análisis descriptivo arrojó coeficientes de asimetría y curtosis adecuados. Los análisis muestran que todas las variables se correlacionan significativamente (p < 0.01). Así mismo, el modelo predictivo de la somnolencia, satisfacción con los estudios y el cansancio emocional presenta adecuados índices de bondad de ajuste (X2 = 7.427, gl = 6, p = .283, X2/gl = 1.238, TLI = 0.994, CFI = 0.998, RMSEA = 0.024 and SRMR = 0.186). Conclusión. En este estudio se presenta un modelo predictivo de la somnolencia, satisfacción con los estudios y el cansancio emocional en estudiantes con altas capacidades intelectuales durante la pandemia por el COVID-19. Se concluye que la actividad física, hábitos alimentarios y la calidad de sueño son predictores de la somnolencia y, a su vez, la ansiedad generalizada, la actividad física y la calidad de sueño predicen el cansancio emocional, que es también un predictor de la satisfacción con los estudios.Citas (OpenAlex): 1metric-badges.view 4 - Algunas métricas están bloqueadas por suconfiguración de consentimiento
Item type:Publicación, Influence of internet and mobile dependence on subjective well-being and reading motivation in schoolchildren: The mediating role of family social support(2025-09-24); ; ; In recent years, dependence on the internet and smartphones has become a significant concern for society. The aim of this study is to determine the mediating role of family social support in the relationship between internet and mobile dependence and subjective well-being and reading motivation in Peruvian schoolchildren. A cross-sectional study was conducted with 972 Peruvian schoolchildren of both genders, aged between 12 and 18 years (M = 14.17, SD = 1.36). Correlation analyses between study variables were performed using Spearman's Rho correlation coefficient. Additionally, a confirmatory factor analysis (CFA) was conducted through structural equation modeling (SEM), and the Weighted Least Squares Mean and Variance adjusted (WLMS) estimation method was employed. The results showed that internet and mobile dependence has a direct effect on family social support. Furthermore, family social support is directly associated with subjective well-being. A positive relationship was also found between family social support and reading motivation. Moreover, it was observed that the effects of internet and mobile dependence on subjective well-being and reading motivation are moderated by family social support. This study supports the existing literature indicating that family social support serves as a mediator in the influence of internet and mobile phone dependency on the subjective well-being and reading motivation of Peruvian schoolchildren. • Analysis of the effect of internet and mobile phone dependence on subjective well-being. • Analysis of the effect of internet and mobile phone dependence on reading motivation. • The mediating role of family social support was examined. • Family social support mediates the effect of internet and mobile phone dependence on subjective well-being. • Family social support mediates the effect of internet and mobile phone dependence on reading motivation.Citas (OpenAlex): 0metric-badges.view 10
