ABSTRACT Objective: To evaluate the influence of obesity on pulmonary function and exercise tolerance in women with obstructive sleep apnea (OSA). Subjects and methods: A descriptive analytic cross- sectional study was carried out. Thirty-nine (39) sedentary climacteric women, aged 45 to 60 years, were evaluated and submitted to polysomnography. The participants were divided into 4 groups: a) ‘eutrophic non-OSA’ (n = 13); b) ‘eutrophic OSA’ (n = 5); c) ‘obese non-OSA’ (n = 6); d) ‘obese OSA’ (n = 15). […]

ABSTRACT Objective To investigate the applicability of predictive equations for resting energy expenditure (REE) in obese individuals with obstructive sleep apnea (OSA) and the effects of OSA severity on REE. Materials and methods Twenty-nine obese men, 41.5 ± 7 years old, with moderate and severe OSA were recruited. All subjects were submitted to a clinical polysomnography, body composition, and indirect calorimetry measurements. REE was also predicted by three different equations: Harris and Benedict (1919), Cunningham (1990), and DRI (2002). Results […]

OBJECTIVE: The aim of this paper was to check the influence of obstructive sleep apnea (OSA) on obesity oxidative stress and CPAP (Continuous Positive Airway Pressure) effect on oxidative stress and in these patients. METHODS: Twenty nine male patients considered obese (BMI > 30kg/m2) were divided into 3 groups: a) Group I: 10 OSA free patients (apnea-hipopnea index (AHI) < 5); b) Group 2: 10 with moderate to serious OSA (AHI > 20); c) Group 3: 9 with OSA from […]

Obstructive sleep apnea and hypopnea syndrome (OSAHS) has been the focus of extensive research because of its association with neurocognitive and cardiovascular complications. The aim of this study was to evaluate the frequency and association between OSAHS and the class of obesity, gender and age in outpatients referred to a sleep laboratory. We selected 1,595 patients, 71.7% male. Mean ± SD age was 46.7 ± 11.7 years, BMI was 28.1 ± 5.1 kg/m2 and AIH was 13.9 ± 15.5 events/ […]
