Psychometric properties of the online Satisfaction with Life Scale in university students from a low-income region.

PURPOSE: To test the feasibility, reliability, and validity of the Satisfaction with Life Scale (SWLS) in an online format in university students from a low-income region. METHODS: This was a psychometric study, involving a study of reliability (n = 117) and validity (n = 195) in university students from a region with a Gini index of 0.56. The scale was applied at two time points with an interval of 2 weeks. This scale measures satisfaction with life based on five statements and responses ranging from 1 to 7 (strongly disagree to strongly agree). We conducted the reliability assessment using temporal stability and internal consistency and construct validity assessment by internal structure solution. RESULTS: All SWLS items showed acceptable (rho > 0.30) and significant (p < 0.05) temporal stability and acceptable internal consistency (alpha > 0.70). In construct validity (internal structure), we identified a factor with an explained variance of 59.0% in the exploratory factor analysis. Additionally, in the confirmatory factor analysis, we identified a one-factor structure solution for SWLS with an acceptable model fitting (chi-square/degrees of freedom [X2/df] = 6.53; Tucker-Lewis Index [TLI] = 0.991; Comparative Fit Index [CFI] = 0.996; root mean square error of approximation [RMSEA] = 0.040; standardized root mean-squared residual [SRMR] = 0.026). CONCLUSION: The Satisfaction with Life Scale, in the online format, is a reliable and valid tool for university students in a low-income context.

Assessment of the validity of a sedentary behavior questionnaire among university students from low-income regions.

Introduction: Introduction: to reduce the prevalence of overweight and obesity, lifestyle interventions, particularly in nutritional education programs, should be prioritized among university students. Monitoring sedentary behavior is an important step toward preventing and controlling obesity. Therefore, we assessed the reliability and validity of an online questionnaire on sedentary behavior among university students from low-income regions. Methods: this cross-sectional methodological feasibility study evaluated the psychometric properties of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) questionnaire. We administered this questionnaire in an online format to 195 and 117 university students (aged between 17 and 53 years) to assess its validity and reliability, respectively. The questionnaire measures the daily time spent watching TV, playing electronic games, using a computer, studying and passive commuting on weekdays and weekends. The questionnaire involved two stages (Q1 and Q2) separated by an interval of 2 weeks. Reliability was assessed using Spearman's correlation analysis. The structural validity of the construct was evaluated by exploratory factor analysis. Results: all variables showed acceptable reliability (Spearman's rho > 0.30 and p < 0.05). Regarding construct structural validity, the exploratory factor analysis identified 4 factors (variance explained: 71.4 %) and did not exclude any items. Conclusion: the online SAYCARE questionnaire exhibited acceptable reliability and structural validity for assessing sedentary behavior among university students from low-income regions.

Introducción: Introducción: para reducir la prevalencia del sobrepeso y la obesidad, las intervenciones en el estilo de vida, particularmente en los programas de educación nutricional, deben priorizarse entre los estudiantes universitarios. Por lo tanto, monitorear el comportamiento sedentario es un paso importante para prevenir y controlar la obesidad. Nuestro objetivo fue investigar la confiabilidad y validez de un cuestionario online sobre comportamiento sedentario entre estudiantes universitarios de regiones de escasos recursos. Métodos: este estudio transversal de factibilidad metodológica evaluó las propiedades psicométricas del cuestionario South American Youth/Child Cardiovascular and Environmental (SAYCARE). Administramos este cuestionario en formato online a 195 y 117 estudiantes universitarios (de entre 17 y 53 años) para evaluar su validez y confiabilidad, respectivamente. El cuestionario midió el tiempo diario del estudiante viendo televisión, jugando a juegos electrónicos, usando una computadora, estudiando y viajando pasivamente entre semana y fines de semana. El cuestionario fue respondido en dos etapas (Q1 y Q2), con un intervalo de 2 semanas. La fiabilidad se evaluó mediante el coeficiente de correlación de Spearman. La validez estructural del constructo se evaluó mediante análisis factorial exploratorio. Resultados: todas las variables mostraron una confiabilidad aceptable (rho de Spearman > 0,30 y p < 0,05). En la validez estructural del constructo, el análisis factorial exploratorio encontró 4 factores (varianza explicada del 71,4 %) y ningún ítem fue excluido. Conclusión: el cuestionario SAYCARE, en formato online, exhibió una confiabilidad y validez estructural aceptables para evaluar el comportamiento sedentario entre estudiantes universitarios de regiones de escasos recursos.

Em relação ao APGAR familiar, (78.8%) dos idosos consideraram suas famílias com boa funcionalidade. Houve correlação significativa negativa de grau moderado (r= -0,5686; p<0,0001), entre os resultados obtidos do APGAR familiar e da Escala de Depressão Geriátrica.Conclusão: Idosos que possuem uma boa funcionalidade familiar, têm menos chances de ter depressão.Assim,faz-se necessária novas pesquisas que correlacionem a funcionalidade familiar com a prevalência da depressão.

Objective: To test the relationship between the quality of family relationships and the prevalence of depressive symptoms in the elderly, in times of the covid-19 pandemic.Method: An exploratory-descriptive study, of a quantitative nature with a cross-section, carried out in a Center for Coexistence and Strengthening of Bonds to the Elderly, in a city in the interior of Maranhão, carried out between August and October 2021. Data collection took place with application of: sociodemographic questionnaire, Geriatric Depression Scale and Family APGAR Scale, to, respectively, identify the profile, prevalence of depressive symptoms and the quality of the elderly's family relationships. For correlation between two numerical variables, Pearson's coefficient was used, adopting a reliability index of 95% and p 0.005. The study was approved by the Ethics Committee for Research with Human Beings under protocol number 4,002,145.Results: The sample included 52 elderlypeople, with a mean age of 71.6 years, with a prevalence of females (75%). The Geriatric Depression Scale identified (37%) elderly people with depressive symptoms. Regarding the family APGAR, (78.8%) of the elderly considered their families to have good functionality. There was a significant negative correlation of moderate degree (r= -0.5686; p<0.0001) between the results obtained from the family APGAR and the Geriatric Depression Scale. Conclusion: Elderly people who have a good family functionality are less likely to have depression. Thus, further research is needed to correlate family functionality with the prevalence of depression.

24 h movement behavior and metabolic syndrome study protocol: A prospective cohort study on lifestyle and risk of developing metabolic syndrome in undergraduate students from low-income regions during a pandemic.

Introduction: Obesity and its comorbidities are increasingly prevalent in Latin America, with a more rapid growth in individuals with lower income. The composition of movement behaviors within a 24 h period may have important implications for obesity, metabolic and mental health in cross-sectional data. However, a longitudinal study is needed to confirm the findings from the primarily cross-sectional evidence. The COVID-19 pandemic has been associated with cardiometabolic outcomes and has impeded healthy behavior. Objectives: The first objective is to evaluate the time elapsed since the diagnosis of not meeting 24 h movement guidelines and the potential subsequent onset of metabolic syndrome in undergraduate students from low-income regions within 4 years of follow up. The second objective is to test the association between 24 h movement, mental wellbeing, eating behaviors, and abdominal obesity in the period of this pandemic. Methods: The 24 h movement behavior and metabolic syndrome (24 h-MESYN) study is a multicentre cohort study that will include participants from two Brazilian cities within the 2022-2025 period to asses the first objective, and also a nested case-control study at the baseline will be carried out to evaluate the second objective. Previously, we conducted a feasibility study in the academic year of 2021 to assessing the psychometric properties of subjective tools, refine our study protocol, and adjust the epidemiological conditions of the cohort's subsequent phases (like as prevalence of exposure of interest, sampling process, and study adherence). Statistical tests as Cohen's kappa agreement; factorial analysis; logistic, Poisson and linear regression; and Kaplan-Meier analysis will be performed, in accordance with the objectives.
