| description | Objective: Obstructive sleep apnoea (OSA) is the most common sleep disorder and its prevalence
has increased with the obesity pandemic. We aimed to explore the presence of OSA in severe
obesity and to evaluate the association of body mass index (BMI) with sleep architecture,
cognition, emotional distress and comorbidities in OSA versus non-OSA patients. Methods: A
sample of 61 patients performed a neuropsychological battery that included tasks of attention,
memory, perceptual/visuospatial ability, vocabulary, inhibition, cognitive flexibility and distress
symptomatology, before overnight polysomnography. Results: More than half of the sample had
OSA. Excessive daytime sleepiness was not a prominent complaint. Sleep architecture was worse
in the OSA than in the non-OSA group, and hypertension was increased with OSA, especially in
the severe OSA group. A higher BMI was associated with cognitive distress and sleep variables and
with type 2 diabetes. The apnoea-hypopnoea index (AHI) was correlated with gender and cognitive
measurements. Cognitive complaints were associated with enhanced distress in both OSA and non-
OSA patients. Discussion: OSA is considerably present in severely obese patients. The BMI was
strongly associated with other important anthropometric measurements along with worsening sleep
architecture and lower executive functioning, both of which may contribute to weight gain. The
AHI was significantly higher in men and affected memory and maintaining sets on the Wisconsin
Card Sorting Test which may represent a barrier to treatment adherence for this disorder. The
substantial presence of cognitive complaints in OSA and non-OSA patients suggests the need for
psychological intervention focused on adaptive coping strategies, mostly for depressive symptoms.
Given the current obesity epidemic, these results support the need for routine sleep investigation
in obese people, particularly in primary care settings. BMI, neuropsychological and emotional
screening can provide crucial information about asymptomatic and high-risk patients who require
prompt sleep intervention and obesity treatment. |
