[Fewer hours of sleep associated with increased body weight in chilean university nutrition students]. / Menos horas de sueño asociado con sobrepeso y obesidad en estudiantes de nutrición de una universidad chilena.

The aim of the study was to determine the association between fewer hours of sleep and excess weight/obesity in first- to fourth-year nutrition students at Universidad de San Sebastian in Chile. A total of 635 students were evaluated, of whom 86.4% were women. The Pittsburg sleep survey was administered to each student along with an anthropometric evaluation, and the body mass index of each was calculated. A raw and adjusted analysis of logistic regression was performed. A total of 57.1% of students slept less than the recommended amount. Sleeping less was associated with excess weight or obesity in the model adjusted for age and daytime sleepiness (adjusted OR [aOR], 1.84; 95% CI, 1.26-2.68), and adjusted for age, smoking, dairy, fruit, and legume consumption; and daytime sleepiness (aOR, 1.83; 95% CI, 1.29-2.76). There is an association between fewer hours of sleep and higher body mass in this population; this should be considered in excess weight prevention.

Menos horas de sueño asociado con sobrepeso y obesidad en estudiantes de nutrición de una universidad chilena / Fewer hours of sleep associated with increased body weight in chilean university nutrition students

RESUMEN El objetivo del estudio fue determinar la asociación entre menor número de horas de sueño y sobrepeso/obesidad en estudiantes de nutrición de primero a cuarto año, de la Universidad San Sebastián en Chile. Se evaluaron 635 estudiantes, de los cuales el 86,4% fueron mujeres. A cada estudiante se aplicó la encuesta de sueño de Pittsburg, una evaluación antropométrica y se calculó el índice de masa corporal. Se realizaron análisis de regresión logística crudo y ajustado. El 57,1% de estudiantes duerme menos de lo recomendado. Dormir menos se asocia con sobrepeso u obesidad en el modelo ajustado por edad y somnolencia diurna (ORa: 1,84; IC 95%: 1,26-2,68) y ajustado por edad, consumo de tabaco, lácteos, frutas, verduras, leguminosas, somnolencia diurna (ORa: 1,83; IC 95%: 1,29-2,76). Existe asociación entre menos horas de sueño y mayor peso corporal en esta población, siendo un factor que considerar en la prevención de sobrepeso.

Patrones alimentarios asociados a un peso corporal saludable en estudiantes chilenos de la carrera de nutrición y dietética / Food patterns associated with a healty body weight in Chilean students of nutrition and dietetics

Objetivo: determinar los patrones de alimentación y asociar el consumo de diversos alimentos con el estado nutricional de estudiantes universitarios chilenos de Nutrición y Dietética. Material y métodos: estudio transversal. Se evaluaron 634 estudiantes de Nutrición y Dietética de la Universidad San Sebastián de las ciudades de Santiago, Concepción, Valdivia y Puerto Montt. A cada estudiante se le aplicó una encuesta alimentaria y se le realizó una evaluación antropométrica. Resultados: el 68% de los estudiantes consume desayuno diariamente, 36,1% y 37,1% consume las porciones recomendadas de frutas y verduras, el 64,9% consume bebidas azucaradas frecuentemente. Se observa una asociación entre un buen peso corporal y el consumo de verduras (≥ 2 porciones/día) OR = 0,662 (0,440-0,996), alimentos integrales OR = 0,474 (0,224-1,002) y un bajo consumo de frituras y snack dulces OR = 0,643 (0,406- 1,019) y OR = 0,545 (0,360-0,825), respectivamente. Conclusiones: los estudiantes presentan una ingesta insuficiente de alimentos saludables y un elevado consumo de alimentos poco saludables, además se observa que la ingesta de verduras y cereales integrales, así como un bajo consumo de frituras y bocadillos dulces se asocian a un estado nutricional normal en los estudiantes evaluados (AU)

Material and methods: cross-sectional study, 634 students were evaluated Nutrition and Dietetics at the Universidad San Sebastián, of Santiago, Concepción, Valdivia and Puerto Montt.

Results: 68% of students eat breakfast daily, 36.1% and 37.1% consume the recommended servings of fruits and vegetables, 64.9% consume soft drinks frequently. A positive association was observed between an adecuated weight and the fact of eat vegetables (≥ 2 servings/day) OR = 0.662 (0.440 to 0.996), whole grains OR = 0.474 (0.224 to 1.002), low consumption of fried and sweet snack OR = 0.643 (0.406 to 1.019) and OR = 0.545 (0.360 to 0.825) respectively.
