Título

Sleep quality in obese elderly people with or without sarcopenic obesity: A cross-sectional study

Introdução

Both obesity and sarcopenia are associated with poor sleep quality. It is, therefore, plausible to speculate that the coexistence of both conditions (i.e., sarcopenic obesity) could potentiate their negative effects on sleep quality.

Objetivo

To investigate whether elderly with sarcopenic obesity have a worse sleep quality than non-sarcopenic obese elderly.

Métodos

Twenty-eight elderly individuals were assessed for sleep quality using the Pittsburgh Sleep Quality Index (PSQI). Sarcopenia was determined based on the Foundation for the National Institutes of Health (FNIH) criteria, whereas obesity was determined in accordance with the World Health Organization (WHO) standards (i.e.; Body Mass Index [BMI] ≥30kg/m²). Student`s t-test was used to compare groups.

Resultados

Fourteen out of the 28 individuals were classified as non-sarcopenic obese (O = 77.6 ± 7.4y; 35.8 ± 4.4Kg/m²) and 14 were classified as sarcopenic obese (SO = 79.4 ± 6.1y; 35.8 ± 3.6Kg/m²). SO group had worse overall sleep score than O group (8.7 ± 4.9 vs. 5.2 ± 2.9; p=0.032). In addition, 50% (n=7) of non-sarcopenic obese elderly had an overall score of ≥5, while 86% (n=12) of sarcopenic obese elderly were characterized as poor sleepers.

Conclusões

Our preliminary data suggest that elderly people with obesity present with high prevalence of low sleep quality, which seems exacerbated by the coexistence of sarcopenia.
