Influencia del cronotipo, horario y calidad nutricional de la merienda en la composición corporal de adultos jóvenes del Club Juvenil Tililag de la ciudad de Guaranda. 2022

Abstract

The objective of this study was to determine the influence of chronotype, eating time and nutritional quality of dinner in the body composition of young adult at the Tililag Youth Club in the city of Guaranda in 2022. The sample was determined through non-random sampling for convenience in which the whole universe was considered. The studied variables were as follows: sex and age; chronotype determined through the questionnaire of Horne and Ostberg; body composition (BMI, percentage of fat mass, percentage of muscle mass, visceral fat level, and metabolic age) determined by the use of bioelectrical impedance scale (OMROM HBF -514C); the time and nutritional quality (kcal, carbohydrates, protein, fats, %IR of dinner) through a 24-hour reminder (two weekdays and one day on the weekend); and the quantitative analysis of the standardized caloric value by using the Ecuadorian food composition table. It was found that most people in the sample are of intermediate chronotype. They have a normal nutritional status according to their BMI values, visceral fat and percentage of muscle mass; however, females have a higher percentage of fat mass. It is concluded that concerning the eating time, most subjects of all chronotypes ingest their dinner between 8:00 and 9:00 pm. The evening subjects have excessive ingestion of fats. It is recommended to conduct research in different age groups in order to identify the differences in chronotype and their changes as age increases or decreases according to sex and to relate them to variables similar to those studied.
