Anthropometric Characteristics, Diettic Intake and Chronotype in Ecuadorian Adults

Abstract Anthropometric characteristics in a subject are a good indication of their body-weight status and diagnosis of overweight and obesity. O and O multifactorial, so today the curiosity arises to investigate new risk factors that predispose to increased body weight, including chronotype. The objective of this study is to evaluate the anthropometric characteristics and caloric intake according to the chronotype in sick Ecuadorian adults. This cross-sectional study consisted of 400 men and women aged between 18 and 63 years, who were hospitalized at the Enrique Garcés General Hospital in the city of Quito. Anthropometric measurements were taken using ISAK techniques. Calorie intake was measured by a 24-hour recall and food frequency, and the Horne and Osttberg questionnaire was applied to measure the chronotype of the subjects. Statistical analyses were performed in R and R studio software. The study subjects were classified into 4 groups depending on their chronotype: moderate morning, extreme morning, intermediate, and moderate evening. It was observed that moderate evening subjects had higher values of body weight, high waist circumference, high triceps skinfold, high percentage of fat mass, visceral fat, and caloric intake than the other groups (p < 0.05). Evening chronotype appears to be related to overweight and obesity and caloric intake.
