Actividad física y estado nutricional en trabajadoras mayores de 50 años de la Escuela Latinoamericana de Medicina. Año 2017 /Physical activity and nutritional status in workers over 50 years of the Latin American School of Medicine. 2017 Actividad física y estado nutricional en trabajadoras mayores de 50 años de la Escuela Latinoamericana de Medicina. Año 2017 /Physical activity and nutritional status in workers over 50 years of the Latin American School of Medicine. 2017Objetivo: determinar el tipo de actividad física y su relación con el estado nutricional de trabajadoras mayores de 50 años de la Escuela Latinoamericana de Medicina.Materiales y Métodos:se realizó un estudio descriptivo, transversal durante los meses de septiembre a diciembre del año 2017. El universo estuvo compuesto por 207 trabajadoras del área docente de la Escuela Latinoamericana de Medicina con una muestra de 29 trabajadoras mayores de 50 años, seleccionada mediante un muestreo aleatorio simple.Resultados: el grupo de 55 a 60 años fue el más numeroso, el valor promedio del IMC fue de 28 Kg/m2 y el de la circunferencia abdominal (CA) de 96,2 cm, valores que traducen un riesgo sustancialmente incrementado, tipo de actividad física las trabajadoras estudiadas emplean 1 día por semana para la actividad intensa, de este gruposolo el 17,2% realiza actividad intensa, para la actividad moderada y ligera 1,3 y 4,4 días, respectivamente. Las trabajadoras obesas no realizaron actividad física intensa y la media permanecieron sentadas 7 horas al día.Conclusiones: las trabajadoras estudiadas emplean un tiempo inferior a lo recomendado para la actividad física y se determinó que hay relación entre el estado nutricional y la actividad física, las clasificadas como obesas no practican actividad física intensa y la media dedica solo un día para la actividad moderada.ABSTRACTObjective: to determine the type of physical activity and its relationship with the nutritional status of workers over 50 years of the Latin American School of Medicine.Materials and Methods: a descriptive, cross-sectional study was carried out during the months of September to December of the year 2017. The universe was made up of 207 workers of the teaching area of the Latin American School of Medicine with a sample of 29 workers older than 50 years, selected by simple random sampling.Results: the group of 55 to 60 years was the most numerous, the average value of the BMI was 28 Kg / m2 and that of the abdominal circumference (CA) of 96.2 cm, values that translate a substantially increased risk, type of physical activity the studied workers used 1 day per week for intense activity, of this group only 17.2% performed intense activity, for moderate and light activity 1.3 and 4.4 days, respectively. The obese workers did not perform intense physical activity and the average remained seated 7 hours a day.Conclusions: the studied workers used a time less than what was recommended for physical activity and it was determined that there is a relationship between nutritional status and physical activity, those classified as obese do not practice intense physical activity and the average dedicates only 1 day for the activity moderate.
