Antecedentes. La obesidad infantil es entendida como una problemática del siglo XXI por la Organización Mundial de la Salud; ENSIN 2010 reportó exceso de peso en 18,9% de los niños entre los 5 y 9 años.
Objetivo. Identificar la actividad física, actividades sedentarias y hábitos alimentarios en escolares entre los 5 y 10 años con exceso de peso de una institución educativa en Bogotá, Colombia.
Materiales y métodos. Valoración nutricional antropométrica (T/E e IMC/E), estándares de crecimiento OMS 2006-2007, puntos de corte Resolución 2121 y OMS, actividad física medida por podometría, actividades sedentarias y hábitos evaluados por encuesta, consumo energético por registro de alimentos de tres días, análisis de datos empleando estadística descriptiva con Microsoft Excel 2011 para Mac y EpiInfo 7.
Resultados. Edad 8 años 5 meses ± 1 año y 3 meses, 53,8% masculino, 41,8% escolares obesos, 7.462 ± 3.028 pasos/día, escolares sedentarios (57,8%), actividades sedentarias de 2 a 4 horas/día (52,6%), energía 1.842 ± 464 Kcal/día, distribución calórica: proteína (15 ± 1%), grasa (30 ± 4%) y carbohidratos (56 ± 4%).
Conclusiones. Escolares con exceso de peso, actividad física baja y sedentarismo, actividades sedentarias mayores a dos horas e ingesta energética incrementada con distribución del valor calórico total adecuado.
Background. Childhood obesity is a problem affecting the 21st century, according to the World Health Organization. The ENSIN 2010 reported 18.9% of children aged 5 to 9 years-old being overweight.
Objective. Ascertaining the physical activity, sedentary behaviour and dietary habits of 5- to 10-year-old overweight children attending a school in Bogota, Colombia.
Materials and methods. This study involved anthropometric nutritional assessment (H/A and BMI/A) using WHO growth standards 2006-2007 and Resolution 2121 and WHO cutoff points. Physical activity was measured by pedometer, sedentary activities and habits were assessed by survey and energy was evaluated by 3-day record of food intake. Microsoft Excel 2011 for Mac and Epilnfo 7 were used for data analysis (descriptive statistics).
Results. Average age was 8 years 5 months (± 1 year and 3 months); 53.8% of the sample was male. BMI showed that 41.8% were obese, 7,462 ± 3,028 steps/day were recorded, 57.8% were classified as being sedentary students (sedentary activities lasted 2-4 hours/day (52.6%) and energy expenditure was 1,842 ± 464 kcal/day. Recommended dietary allowance (RDA) regarding calorie distribution was 15 ± 1% protein, 30 ± 4% fat and 56 ± 4% carbohydrates.
Conclusions. It was found that students had excess weight, were sedentary and had a low level of physical activity. Sedentary activities lasted more than two hours per day and energy intake was increased regarding the norm for this age-group; however, RDA concerning total calories was adequate for such age-group.
