Short sleep duration is associated with high energy and total lipid intake in obese women: a pilot study

Year: 2023

Abstract: ABSTRACT Objective To evaluate the influence of self-reported sleep duration on ghrelin secretion and nutritional indicators in obese women. Methods This is an observational study, including 36 adult women with obesity. Sleep duration was reported while completing the general questionnaire. Dietary, laboratory, anthropometric, and body composition indicators, and resting metabolic rate, were evaluated. For statistical analysis, sleep duration data were grouped into tertiles: less than six (first tertile); equal to or above six; and less than eight (second tertile); equal to or greater than eight hours of sleep per day (third tertile). The indicators were compared for the different ranges of the sleep duration. Results There was no significant difference when comparing anthropometric, laboratory, and energy expenditure indicators between sleep tertiles. However, women with shorter sleep duration (less than 6 hours per day) had a higher mean caloric intake, compared with the tertile of eight hours or more of sleep per day. For total lipid intake, the mean consumption was higher in the first tertile (up to six hours a day). Conclusion Sleeping less than six hours a day led to an increase in energy and lipid intake in obese women. However, it did not change the plasma ghrelin concentration.
