ABSTRACT
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)
Background Lifestyle is a theoretical construct that is formed by the life habits of a subject. The analysis and objective quantification of lifestyle can have a great impact on people's health, as well as on the evolution of its status over the years. The objective of this research has been the validation of the Acquired Healthy Lifestyle Assessment Scale (E-VEVSA) in Spanish adults. 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)

INTRODUCTION: A sedentary lifestyle is indicated in the international literature as one of the main causes for the onset of some cardiovascular risk factors. OBJECTIVE: To assess the effect of a therapeutic physical exercise programme on different clinical indicators related to dyslipidaemia (total cholesterol, HDL and LDL) in sedentary subjects with a cardiovascular risk factor. METHOD: Intervention study with before-and-after evaluation of a sample of 340 patients (132 males and 208 females) referred from the 2 primary care centres of the municipality of Molina de Segura (Murcia), and who participated in a 30-week programme of physical exercise combining muscle-conditioning work circuits with other cardio-respiratory resistance workouts. Regarding the clinical indicators, the health professionals collected in the medical history the health indicators corresponding to the biological evolution of the process for which the subjects studied had started the physical exercise programme. RESULTS: The statistical analyses showed a significant improvement (p<.005) in the LDL indicator and a non-significant improvement in total and HDL cholesterol indicators after a 3-month exercise programme of 3 weekly sessions. CONCLUSIONS: The prescription of physical exercise in dyslipidaemic subjects from primary care centre should be evaluated as a resource for improving the clinical indicators specific to their pathology.
