No prior studies have examined the reliability properties of the 16-item Mediterranean Diet Quality Index (KIDMED) questionnaire among young adults from a non-Mediterranean country. The objective of this study was to determine the psychometric properties in terms of the reliability and validity of the KIDMED questionnaire in young adults from Colombia. A cross-sectional validation study was conducted among 604 Colombian college students (47.51% men and 52.48% women; mean age of 21.60 ± 2.02 years). Kappa statistics were used to assess the reliability of the KIDMED questionnaire. A categorical principal components analysis was used to determine validity. Based on the KIDMED score, 58.4% of students had a good adherence to the Mediterranean diet (MedDiet). Good agreement in the general score of the questionnaire was observed (κ = 0.727, 95% confidence interval = 0.676 to 0.778, p < 0.001). A five-factor model was identified which explained almost 51.38% of the variability, showing the multidimensionality of the questionnaire. In conclusion, this study provides reasonable evidence for the reliability and validity of the KIDMED questionnaire for assessing adherence to MedDiet in college students within a Latin American country. The evaluation of the psychometric properties of this tool in early adulthood and in a non-Mediterranean country will be useful in clinical practice and epidemiological research, since practitioners and health researchers now have a valid and reliable short scale.

The aim of the present study was twofold: first, to determine the meeting all three 24‐h movement guidelines in Colombian preschool‐aged children, and second, to explore the associations between different socio‐ecological correlates and the meeting of these guidelines. This was a cross‐sectional study with data from the Encuesta Nacional de Situación Nutricional (ENSIN‐2015) in Colombia, 2015–2016. The sample comprised 3002 low‐income preschoolers (3–4 years old, 50.7% boys). Data on physical activity, screen time, and sleep time were collected using the Cuestionario para la Medición de Actividad Física y Comportamiento Sedentario, reported by their parents. In total, 18 potential correlates (individual, interpersonal, organizational, and community level) were analyzed. Backward binary logistic regression analysis was performed with the potential correlates as independent variables and meeting all three 24‐h movement guidelines as dependent variables. The prevalence of preschoolers meeting all three 24‐h movement guidelines or none was 4.8% and 16.6%, respectively. In the final model, boys (odds ratio [OR] = 1.87, 95% confidence interval [CI] 1.00–3.50) and those who do not have television in their bedroom (OR = 2.09, 95%CI 1.05–4.14) were more likely to meet all three 24‐h movement guidelines compared to with girls and those who have television, respectively. In conclusion, strategies to promote adherence to all 24‐h movement guidelines among low‐income preschoolers are warranted, and should focus on actions considering the importance of sex and home environment changes to support these movement behaviors.

There is evidence supporting that acute sprint interval training (SIT) might improve metabolic responses to postprandial glucose, but results are inconclusive. The aim of the present study was to explore the effects of acute SIT on metabolic response and substrate utilization in individuals with overweight/obesity after an oral 75‐gram glucose challenge. Thirty‐three participants with overweight/ obesity (32.7 ± 8.3 years, 24 male, 9 female) participated in the study and a crossover design was followed. After the 75‐gram glucose load, participants were randomly allocated to two groups: no exercise (resting) or SIT protocol. Metabolic data including respiratory quotient (RQ) and substrate utilization rates (fats and carbohydrates) were collected using the COSMED Q‐NRG + ® calorimeter. The RQ was significantly lower in the acute SIT group (0.76 [0.01];p < 0.0001) than in the resting group (0.80 [0.01];p = 0.036) at the 120‐min postprandial time point, and the RQ area under the curve (AUC) was also lower in the SIT group (mean difference of −6.62, 95% CI −12.00 to −1.24;p = 0.0161). The contribution of fat to energy expenditure increased after SIT during the postprandial period whereas the contribution of carbohydrates decreased. The AUC for fat contribution was significantly higher (mean difference 2311.9, 95% confidence interval [CI] 578.8 to 4043.3;p = 0.0098) and the AUC for carbohydrate contribution was significantly lower (mean difference −2283.1, 95% CI −4040.2 to −527.1;p = 0.0117) in the SIT group than in the resting group. In conclusions, acute SIT might have a positive effect on metabolic responses to postprandial glucose and, accordingly, should be recommended for improving metabolism in people with overweight/obesity.

Sedentary behavior (SB) is influenced by variations in social, cultural and economic contexts. This study assesses the test–retest reliability and validity of the Youth Leisure-time Sedentary Behavior Questionnaire (YLSBQ), a self-report tool that examines total and domain-specific SB in a cohort of young adults from Colombia. A cross-sectional validation study was conducted among 447 Colombian college students (52.8% men; mean (± standard deviation) age of 19.55 ± 2.54 years). To assess the reliability of the YLSBQ, Kappa statistics (k) were used. A confirmatory factor analysis (CFA) was conducted to determine validity. The Cronbach alpha for the 12 behaviors of the YLSBQ showed a good-to-excellent internal consistency (0.867, ranging from 0.715–0.935). Intraclass correlation coefficient (ICC) indicated that 10 items (83.0%) and two items (17.0%) showed excellent and good reliability, respectively. Furthermore, ICC between the total sedentary time was 0.926 (95% confidence interval [CI] = 0.912 − 0.939), which was interpreted as excellent. The goodness-of-fit tests provided evidence that overall, a four-factor solution was an adequate fit with the time scores. In conclusion, the YLSBQ could be considered a reliable, valid and usable tool for the assessment of SB in young adults in a Latin American country. We found that the psychometric properties of the questionnaire were similar to those of the original Spanish validation study.

El propósito de esta investigación fue describir la relación entre la condición física y el riesgo de caídas en un grupo de personas mayores del servicio médico de una universidad pública de la ciudad de Cali, Colombia. Este estudio incluyó 32 personas mayores (12 hombres y 20 mujeres). Ellos fueron evaluados por medio de las baterías de pruebas del SPPB y Senior Fitness Test. El procesamiento y análisis de la información se llevó a cabo con el programa SPSS v. 27 para Windows. Los principales hallazgos revelan una prevalencia de riesgo de caídas de 62,5% dentro del grupo, capacidad aeróbica por encima del percentil 50 en las mujeres, altos valores de fuerza en miembros inferiores, superiores y fuerza prensil para todo el grupo; también se encontraron correlaciones moderadas significativas entre la puntuación total del SPPB y la fuerza en miembros inferiores y superiores (r=0,57 p<0,001 y r=0,53 p<0,001) y entre el puntaje total del SPPB ,la agilidad y equilibrio (r=-0,44 p<0,05), test de equilibrio y agilidad ,y equilibrio (r=-0,43 p<0,05). En este estudio se encontraron valores superiores a la media en la mayoría de las pruebas de condición física; sin embargo, estos hallazgos contrastan con la presencia latente de un riesgo de caídas en este grupo, lo cual plantea la necesidad de hacer modificaciones estructurales al programa de ejercicio físico que actualmente siguen los adultos mayores. Palabras clave: SPPB, riesgo de caídas, ejercicio físico, equilibrio, marcha. (Fuente: DeCS). The aim of this research is to describe the relationship between physical condition and the risk of falls in a group of elderly people from the medical service of a public university in the city of Cali, Colombia. This study included 32 older people (12 men and 20 women). They were assessed through the SPPB and Senior Fitness Test batteries. The processing and analysis of information were conducted using SPSS v.27 for Windows. The main findings revealed a prevalence of falls risk of 62.5% within the group, aerobic capacity above the 50th percentile in women, high values of strength in lower and upper limbs and prehensile strength for the entire group. Significant moderate correlations were also found between the total score of the SPPB and the strength in lower and upper limbs (r=0.57 p<0.001 and r=0.53 p<0.001) and between the total score of the SPPB and agility and balance (r=-0.44 p<0.05), balance and agility test, and balance (r=-0.43 p<0.05). In this study, values above the mean were found in most physical condition tests; however, these findings contrast with the latent presence of a risk of falls within this group,which suggests the need for structural modifications to the physical exercise program currently followed by older adults. Keywords: SPPB, risk of falls, physical exercise, balance, march. (Fuente: DeCS).
