RESUMO

En el presente estudio se utilizaronlas recomendaciones de la Organización Mundial de la Salud para medir el estado nutricionalde alumnos(as) de kínder y primero básico de dos colegios municipales de la región del Maule, a través del índice de masa corporal. Tiene como propósito relacionarel estado nutricional con los hábitos alimenticios y la actividad física percibida por los padres. Se evaluaron a 87 alumnos de kínder y primero básico. Los resultados muestran que, en kínder, el sobrepeso y obesidad alcanzó un 76,2% y en primero básico un sobrepeso y obesidad del 70,6%,sin embargo, no se encontró mayor relación entre el conocimiento de los padres sobre la importancia de la actividad físicay loshábitos alimentarios en la vida de sus hijos y su estado nutricional. Los alumnos se encuentran en un estado nutricional de riesgo y la percepción de los padres es baja en cuantoa la influencia estos factores, relacionándose directamente con el mal estado nutricional que estos presentan

The present study used the recommendations of the World Health Organization to measure nutritional status, doing so through the body mass index. The purpose of the study is to relate the nutritional status of kindergarten and first grade students from two municipal schools in the Maule region with the eating habits and physical activity perceived by the parents. 87 kindergarten and first grade students were evaluated. The results show that in kindergarten overweight and obesity reached (76.2%) respectively, and in first grade an overweight and obesity of (70.6%), however, no greater relationship was found between knowledge of the parents of the importance of physical activity in the life of their children and their nutritional status as well as in the eating habits that they reported of their children in relation to nutritional status. Students are in a nutritional state of risk and the perception of parents is low in terms of the knowledge they have regarding the practice of physical activity and eating habits, being directly related to the poor nutritional status that they present

RESUMO

BACKGROUND: Studies based on Body Mass Index (BMI) and waist circumference (WC) are generally used to examine the prevalence and tendency of overweight and obesity. These studies help determine the socioeconomic development of a country and improve public health policies. Therefore, the goal of this research was to determine the trend of change in abdominal obesity of Chilean university students according to the Body Mass Index (BMI) measured in intervals of three and six years. METHODS: For this study, a total of 1598 students of both sexes ranging in age from 18 to 26 from a Chilean university were evaluated. Students were assessed commencing in 2007 (372 males and 315 females), 2010 (250 males and 330 females), and ending in 2013 (153 males and 178 females). During the three transversal assessments, weight, height, and waist circumference were evaluated. BMI was calculated for both sexes. RESULTS: No significant differences were found in age and BMI during the three years evaluated (2007, 2010, and 2013). In 2013, waist circumference (WC) increased significantly (p < 0.001 for both sexes). Moreover, in 2013, in all the percentiles evaluated, high values of WC were compared in relation to previous years. Furthermore, in 2013, in all four BMI categories (underweight, normal, overweight, and obese), the university students showed significant increases in WC (Females: p = 0.004; Males: p = 0.035) whereas in 2007 and 2010, the values remained relatively stable. CONCLUSIONS: BMI remained constant during 2007, 2010, and 2013. However, the university students of both sexes showed greater risk of abdominal obesity as a result of increased WC in 2013.

RESUMO

OBJECTIVE: a) describe changes in body adiposity, b) quantify the increase in blood pressure and c) verify if blood pressure increases according to the categories of body fatness in two cohorts (2009-2014) in university students. METHODS: two transverse measurements made in 2009 and 2014. The 2009 sample consisted of 309 university students (138 men and 171 women) and 2014 by 319 young people (136 men and 183 women) were compared. Weight, height, body mass index, waist circumference and systolic and diastolic blood pressure were evaluated. RESULTS: males were significantly increased body adiposity (BMI = 1.9 kg/m2 and CC = 6.4 cm), (p < 0.001), while women increased blood pressure (DBP = 5.7 mmHg and SBP = 6.6 mmHg) as a function of body fat in a range of 5 years (p < 0.001). CONCLUSION: males increased their body fat, while women increased blood pressure. The results suggest the adoption of healthy lifestyles to combat excess weight and the presence of hypertension in young students.

Objetivo: a) describir los cambios de la adiposidad corporal, b) cuantificar el incremento de la presión arterial y c) verificar si la presión arterial aumenta en función de las categorías de la adiposidad corporal en dos cohortes (2009-2014) en jóvenes universitarios. Métodos: se comparó dos mediciones transversales efectuadas en el año 2009 y 2014. La muestra del 2009 estuvo constituida por 309 universitarios (138 varones y 171 mujeres) y la del 2014 por 319 jóvenes (136 varones y 183 mujeres). Se evaluó peso, estatura, índice de masa corporal (IMC), circunferencia de la cintura (CC) y presión arterial diastólica (PAD) y sistólica (PAS). Resultados: los varones aumentaron significativamente en la adiposidad corporal (IMC = 1,9 kg/m2 y CC = 6,4 cm), (p < 0,001), mientras que las mujeres incrementaron la presión arterial (PAD = 5,7 mmHg y PAS = 6,6 mmHg) en función de la adiposidad corporal en un intervalo de 5 años (p < 0,001). Conclusión: los varones incrementaron su adiposidad corporal, mientras que las mujeres aumentaron la presión arterial. Los resultados sugieren la adopción de estilos de vida saludables para combatir el exceso de peso y la presencia de hipertensión arterial en los jóvenes universitarios.
