Daytime sleepiness is related to lower consumption of natural or minimally processed foods in women with severe obesity

Introdução

The prevalence of obesity and related disorders has been increasing gradually in recent years and is a public health problem. One of the factors associated with weight gain is poor sleep quality. Previous studies have shown that sleep inefficiency is related to preferences for foods with higher energy density. Recently, the degree of food processing has gained attention as a new look to classify the food profile. However, few studies have evaluated the influence of sleep quality on food intake according to the degree of processing.

Objetivo

The aim of this study was to evaluate whether sleep quality is related to food intake, according to the new food processing classification (NOVA).

Métodos

Forty-one women with severe obesity were evaluated. Food intake was assessed by a food frequency questionnaire (FFQ), then classified according to NOVA (Ministério da Saúde, 2014), in fresh or minimally processed foods; processed foods and ultra-processed foods. The frequency of food intake was transformed into a score as described by FORNÉS (2002). Sleep quality was assessed by the Epworth sleepiness scale (ESS) and the women were grouped according to classification as normal level of daytime sleepiness (NDS) and excessive daytime sleepiness (EDS). Normality was evaluated by the Shapiro Wilk test and the t. test for an independent sample was performed to evaluate the association between sleep and food intake using the RStudio software. The present was approved by the Ethics and Researsh Committes of the Hospital Geral de Goiânia.

Resultados

Regarding daytime sleepiness, 59.5% of the women were classified as NDS and 40.5% as SDS. The volunteers classified as normal had a mean age of 40 years, BMI 48.4 kg/m2 and had an average consumption of fresh foods two to four times a week, processed foods, once a week and consumption of ultra-processed foods, one to three times a month. The volunteers classified as excessive daytime sleepiness had a mean age of 43.3 years, BMI 48.6 kg/m2 and had an average consumption of fresh foods, once a week, of processed foods, once a week, and consumption of ultra-processed foods, one to three times a week. It was observed that in EDS group the frequency of natural or minimally processed food was significant lower than in NDS group (p<0.00).

Conclusões

The results suggest that EDS might influence in food choice leading to lower consumption of in natural and unprocessed food among women with severe obesity.
