Relación entre índice de masa corporal, la forma de sueño y el nivel de actividad física evaluados por acelerometría en escolares de primaria de una Institución Educativa Distrital (I.E.D). Bogotá.

Abstract

Introduction: low levels of physical activity and sleep in schoolchildren are a major problem, which need to be evaluated. The accelerometry measurement is the most reliable and objective method for the timely detection of these. Objective: Identify the relationship of the Body Mass Index with the form of sleep and levels of Physical Activity through accelerometry, in schoolchildren of a district educational institution. Methods: Descriptive cross-sectional design was performed in 13 schoolchildren (53.8% children) between the ages of 9.0 and 13.9, belonging to a district educational institution. Physical activity and sleep form levels were identified by ActiGraph GT3X/+accelerometers and the Body Mass Index (BMI) by the bioimpedance scale. Results: The mean age of those evaluated was 11.35 0.149 years. Observing a significant value of p < 0.05 in the mean differences in BMI, weight, height, age and sex. Accelerometry showed an average for total bedtime (TTC) of 9.14 hrs, total sleep time (TTS) 6.57 hrs and the percentage of sedentarism (81.86%); the number of awakenings during the night was identified with an average of 19.49 times. Conclusion: Greater sedentarism was identified in school children, total time in bed and less sleep, however, no relationship was found between the study variables. A larger sample size is required for better analysis of the variables.
