The work-health balance questionnaire: cultural adaptation and validation in Spanish

El objetivo de este estudio fue hacer una adaptación cultural del cuestionario del balance trabajo-salud (WHBq; (Gragnano et al., 2017) al idioma español y proporcionar evidencia mediante el análisis factorial, la confiabilidad y validez. Este instrumento se compone de tres escalas: Incompatibilidad trabajo-salud (WHI), clima de salud (HC) y apoyo externo (ES), con un total de 17 ítems. Este se aplicó a una muestra de trabajadores mexicanos (n = 316). El análisis factorial confirmatorio reveló un modelo de tres factores reproducido en la estructura original, el cual mostró un buen ajuste (CFI = 0.950; SRMR = 0.051; RMSEA = 0.069). La confiabilidad de cada factor y del cuestionario en su totalidad fue satisfactorio (ω mayor a 0.70). El AVE fue inferior a 0.50 solo en ES. Se discuten las soluciones para este problema. La validez de constructo se evaluó por criterio externo. El WHBq en su versión al español mostró adecuadas propiedades psicométricas y su relación teórica consistente con variables externas. Con estos resultados se confirma que este instrumento es una herramienta válida y confiable para su uso en México.(AU)

This study aimed to adapt the Work-Health Balance question-naire (WHBq; (Gragnano, Miglioretti, Frings-Dresen, & de Boer, 2017)in-to Spanish and to provide evidence for its factorial structure, reliability, and validity. WHBq comprises 17 itemswith three scales: Work-Health In-compatibility (WHI), Health Climate (HC) and External Support (ES). It was applied to a sample of Mexican workers (n =316). Confirmatory factor analysis revealed that the three-factor model replicating the original struc-ture provided good fit (CFI = 0.950; SRMR = 0.051; RMSEA = 0.069). The reliability of each factor and the whole questionnaire were satisfactory (α and ω higher than0.70). The AVE was lower than 0.50 only for ES. So-lutions to this problem are discussed. Concurrent and differential validitywas examined with external criteria.The WHBq in its Spanishversion shows good psychometric properties and theoretically consistent relation-ships with external variables. These findings provide support for its use as a valid and reliable tool in Mexico.(AU)

Factors related to road system organisation and its association with mortality due to motor vehicle-pedestrian collisions in Guadalajara Metropolitan Area.

INTRODUCTION: Traffic events are one of the five leading causes of mortality in Mexico. Pedestrians are one of the main road users involved in such incidents and have the highest mortality rate, which is regularly analysed in relation to vehicles and pedestrians, but not the built environment. The purpose of this study was to analyse the elements of the road system organisation that influences the mortality rate of pedestrians hit by motor vehicles in the Guadalajara Metropolitan Area. METHOD: We designed a case and control study in which the cases were sites where a pedestrian died during 2012. The controls were sites close to where the death occurred, as well as those with road infrastructure characteristics similar to those where the events took place. We obtained the pedestrian data from the death certificates and assessed some of the environmental elements of the road sites. A logistic regression analysis was used to estimate OR; 95% CI. RESULTS: Road system factors related with pedestrian mortality in close locations were: the presence of bus stops on intersections in one street or both, and road system features, such as the presence of traffic islands, vehicle flow and pedestrian flow. CONCLUSIONS: According to the urban network theory and multiple theory, the final elements resulted as risk factors due to a fault in connectivity between the nodes. A temporal analysis of urban features will help urban planners make decisions regarding the safety of pedestrians and other road users.

Consumo diferenciado de macronutrientes según sexo y edad en estudiantes de educación superior / Differentiated consumption of macronutrients according to sex and age in higher education students

RESUMEN Objetivo Analizar la ingesta de macronutrientes y su relación con la edad y sexo en estudiantes de educación superior. Métodos Se realizó un estudio transversal conformado con 218 estudiantes de educación superior de 18 a 30 años. Se utilizó un instrumento validado y confiable, para medir el consumo de macronutrientes. Resultados Respecto a la ingesta de consumo de macronutrientes se observa que hay diferencia estadística por sexo, a favor de los hombres (p>0,05), excepto en el consumo de proteínas en los estudiantes mayores de 25 años. En el grupo etario menor a 20 años, los hombres tienen un mejor consumo de proteínas. En estudiantes de 20 a 25 años el consumo de macronutrientes es parecido entre hombres y mujeres. Discusión Los resultados evidencian que el porcentaje de consumo respecto del valor ideal de requerimiento estimado para actividad ligera según FAO/OMS/ONU 2004, está por debajo, con un déficit de consumo de macronutrientes que oscila entre el 20% y el 60%.(AU)

ABSTRACT Objective To analyze the intake of macronutrients and its relationship with age and sex in higher education students. Materials and Methods A cross-sectional study was carried out with 218 higher education students, aged between 18 and 30 years. A validated and reliable instrument was used to measure macronutrient consumption. Results Regarding the intake of macronutrients, a statistical difference by sex was observed in favor of men (p>0.05), except for the consumption of proteins in students older than 25 years. In the group under 20 years of age, men showed better protein intake. Finally, in students between 20 and 25 years, the consumption of macronutrients is similar among men and women. Discussion The results show that the percentage of consumption with respect to ideal value of the estimated requirement for light activity according to FAO/WHO/UN 2004 is below the recommendations, with a macronutrient consumption deficit that ranges between 20% and 60%.(AU)
