Fiabilidad y validez de la Escala de valoración del estilo de vida saludable adquirido (E-VEVSA) en adultos de Albacete y Murcia (España) / Reliability and validity of the Acquired healthy lifestyle assessment scale (E-VEVSA) in adults from Albacete and Murcia (Spain)

Fundamentos El estilo de vida es un constructo teórico que está formado por los hábitos de vida de un sujeto. El análisis y la cuantificación objetivable del estilo de vida, puede tener un gran impacto sobre la salud de las personas, así como en la evolución del estado de la misma con el transcurso de los años. El objetivo de la presente investigación ha sido la validación de la Escala de valoración del estilo de vida saludable adquirido (E-VEVSA) en adultos españoles. Métodos Sobre una muestra inicial para las pruebas exploratorias de 248 sujetos y final para las pruebas confirmatorias de 780 sujetos, de edades comprendidas entre los 22 y 72 años de edad, se realizaron pruebas psicométricas exploratorias y confirmatorias basadas en el estadístico alfa de Cronbach (fiabilidad) y análisis factorial exploratorio con rotación oblicua (oblimin) y confirmatorio con rotación varimax (validez de constructo), que dieron lugar a un instrumento definitivo formado por 52 ítems y estructurado en siete dimensiones: Responsabilidad individual en el cuidado de la salud (nueve ítems), hábitos de práctica físico-deportiva (seis ítems), hábitos de salud en las relaciones sociales (10 ítems), hábito de consumo de tabaco y alcohol (nueve ítems), hábito de alimentación saludable (siete ítems), hábito de salud psicológica (seis ítems) y hábito de descanso y sueño diario (cinco ítems). Resultados Todos los ítems explicaron una varianza total de 66,87% y un alfa de Cronbach de 0,894, estando por encima de 0,700 el alfa parcial de cada dimensión o factor. Conclusiones Los resultados arrojan pruebas psicométricas que confirman la validez de la escala E-VEVSA como un instrumento útil para medir el estilo de vida saludable adquirido en personas adultas (AU)

Method On an initial sample for the exploratory tests of 248 subjects and a final sample for the confirmatory tests of 780 subjects, aged between 22 and 72 years of age. Exploratory and confirmatory psychometric tests were carried out based on the Cronbach's alpha statistic (reliability) and exploratory factorial analysis with oblique rotation (oblimin) and confirmatory with varimax rotation (construct validity), which resulted in an instrument made up of 52 items and structured in 7 dimensions: individual responsibility in health care (9 items), habits of physical-sports practice (6 items), health habits in social relationships (10 items), habit of tobacco and alcohol consumption (9 items), habit of healthy eating (7 items), psychological health habits (6 items) and daily rest and sleep habits (5 items). Results All the items explained a total variance of 66.87% and a Cronbach's alpha of .894, with the partial alpha of each dimension or factor being above .700. Conclusions The results show psychometric tests that confirm the validity of the E-VEVSA scale as a useful instrument to measure the healthy lifestyle acquired among adults (AU)

Evaluación de un programa de intervención motivacional de actividad física en el tratamiento de la obesidad y el sobrepeso / Evaluation of a motivational intervention of physical activity program in the treatment of obesity and overweight

Objetivo: Analizar la evolución de un programa de actividad física motivada para el tratamiento de la obesidad. Método: Estudio casos-control longitudinal, aleatorizado y controlado, con 2 brazos, 12 meses de seguimiento y una ratio de asignación 1:1. La recogida de datos se hizo entre julio del 2017 y julio del 2018. Los pacientes, mujeres y varones, debían haber sido derivados por sus médicos de empresa con el diagnóstico de sobrepeso u obesidad y una edad entre 20 y 65 años. Se analizan parámetros antropométricos, lipídicos y de seguimiento del programa. Resultados: Han participado 123 pacientes obesos o con sobrepeso (61 en el grupo de intervención [G1] y 62 en el grupo control usual care [G2]), 107 de los cuales han finalizado el estudio (60 en G1 y 47 en G2). Edad media: 45,55±12,83 DE. Sexo: 57,2% mujeres y 42,8% hombres. El seguimiento de los pacientes en el programa es muy superior al grupo control y los abandonos son no significativos (solo hubo uno). Se puede observar que tanto el peso como el índice de masa corporal como los principales parámetros lipídicos se reducen en el grupo de estudio de forma significativa con respecto al grupo control. La actividad física del grupo con intervención de programa de actividad física motivada es 3 veces superior al grupo sin intervención. Se aprecia una relación significativa entre el aumento de la actividad y la reducción de peso (p < 0,001), y también entre esta y la reducción de colesterol y triglicéridos. Conclusiones: En nuestro estudio, un programa de motivación para la actividad física resulta tener más seguimiento y por tanto mejora los parámetros antropométricos y lipídicos

Objective: To analyse the outcomes of a motivational physical activity program for the treatment of obesity. Method: A randomised, controlled, double blind clinical trial with 2 arms, 12 months of follow-up and a 1:1 allocation ratio. The data was collected between July 2017 and July 2018. The patients, of both genders, had to be referred by their occupational medicine doctors with the diagnosis of overweight or obesity and be aged between 20 and 65 years. An analysis was made of the anthropometric measurements, lipid parameters, as well as on the follow-up of the program. Results: A total of 123 obese or overweight patients participated. Two groups were formed; 61 in intervention group [G1] and 62 in as usual care control group [G2]). As regards the 107 that finished the study (60 in G1 and 47 in G2), the mean age was 45.55±12.83 SD, with 57.2% women and 42.8% men. The number of patients followed-up was much higher in the Physical Activity Program than in the control group, and the number of dropouts (only one) was insignificant. It can be seen how both the weight and the body mass index as the main lipid parameters are reduced in the study group significantly with respect to the control group. The physical activity of the group in the motivated physical activity program is three times higher than in the group without intervention. There was a significant relationship between the increase in activity and weight reduction (P<.001), also between the reduction in weight and the reduction in cholesterol and triglycerides. Conclusions: In our study, a motivational physical activity program leads to more follow-up and therefore improves the anthropometric and lipid parameters
