METABOLIC CHARACTERISTICS FROM PATIENTS WITH OBSTRUCTIVE SLEEP APNEA

Introduction: the obstructive sleep apnea (OSA) is a pathology of high prevalence associated with overweight and obesity. The relationship between metabolic syndrome (MS) and OSA has not been reported in our environment. Materials and methods: retrospective study in adults selected for respiratory polygraphy and metabolic evaluation classified according to the presence of MS. Results: we included 302 patients. The prevalence of obesity was 66.88% and MS 62.58%. 19% had symptoms of daytime sleepiness and 48.3% showed 5 or more components of the STOP-BANG questionnaire. Patients with OSA were mostly male, older; body weight, waist and neck circumference compared to the group without OSA (57 vs 49 years, p<0.001; 93.89 vs 85kg, p<0.05; 108 vs. 100 cm, p<0.001 respectively). They showed higher values of triglycerides, systolic blood pressure, obesity and desaturation index (134 vs 99 mg/dl, p<0.001; 134 vs 128 mmHg, p<0.05; 69.2 vs. 52.3%, p<0.05 and 14.6 vs 2 ev/h, p<0.001 respectively). The amount of STOP-BANG components was higher in patients with OSA (5 vs 3; p<0.001). Conclusions: AOS and SM are frequently related and remain underdiagnosed. The use of validated questionnaires facilitates the identification of candidates for sleep studies. It is necessary to implement healthy habits management programs to prevent complications of both pathologies.
