ASSOCIATION BETWEEN FOOD CONSUMPTION AND CHARACTERISTICS OF SLEEP AND CIRCADIAN RHYTHMICITY

Introdução

When studying the inherent aspects of sleep it is important to assess how the quality and quantity of sleep in the last two decades may be one of the reasons for the increase in childhood obesity, which has been growing rapidly worldwide. This study aims to evaluate the association of diet with circadian rhythm in children and adolescents with obesity.

Objetivo

The objective is to evaluate the association of diet with circadian rhythms in children and adolescents with obesity.

Métodos

An analytical observational cross-sectional study was conducted with data collection from 43 patients between 6 and 13 years old diagnosed as overweight seen in outpatient clinics of the public health system. For the analysis of the activity-rest rhythm the study participants used the Actrust model actimeter for a period of 7 days and completed the 6-day Food Consumption Record to collect energy and macronutrient intake.

Resultados

To verify if the food consumption could interfere in the circadian rhythm of the researched patients, the tests of Statistical Analysis Linear Regression and the Binary Logistic Regression were used with the analysis of the "r" through the Correlation Classification for the data collected through of the actimeter and the energy intake of the patients in 6 days of food consumption.
The correlations of energy and macronutrient intake with the variables Relative Amplitude and L5 were negative, while with the M10 Value the correlation was very weak positive, demonstrating that there is no relationship between energy intake and activity-rest in the same period.
In our study, the only parameter to show statistical significance (p<0.05) with the activity-rest data was age in relation to the M10 value, which may be characteristic of greater diurnal activity for older patients with higher food consumption. When comparing the risk for sleep disorders with the parameters of circadian rhythm, the variables L5 onset and M10 onset had a positive association with SVTD, indicating a possible phase change associated with sleep disorders.

Conclusões

No association was identified between macronutrient intake and the Relative Amplitude of the activity-rest rhythm, with the average activity of the day (M10) and with the average activity during the night (L5) in the studied sample.
