“…In a gender comparison study, Cintra and cols. (31) showed that women with OSA in the climacteric period submitted to maximum effort test had lower oxygen consumption (VO 2 ), reduced maximum heart rate (HRmax) and lower pressure levels than the ones found in men, which suggest that women with OSA have peculiarities during and after aerobic exercise.…”

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 crosssectional 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). All subjects underwent clinical and anthropometric evaluation, followed by pulmonary function tests and 6-minute walk test (6MWT). Results: There was a significant difference in the predicted percentage values of FEV 1 /FVC when comparing 'eutrophic OSA' and 'obese OSA' (97.6% ± 6.1% vs. 105.7% ± 5.7%, respectively; p = 0.025). The other spirometric variables did not show any differences between the studied groups. There was no significant difference in the maximum distance walked when the 'eutrophic non-OSA', 'eutrophic OSA', 'obese non-OSA' and 'obese OSA' groups were compared. Conclusion: Considering the results of this study, OSA itself did not influence pulmonary function or functional capacity parameters compared to eutrophic women. However, not only isolated obesity but also obesity associated with OSA can negatively impact sleep quality and lung function.

“…16,17 OSA severity has been associated with self-reported lack of exercise and potentially impairs exercise performance. 18 Sleep duration is another modifiable risk factor that may impact BP, physical activity, and sedentary behaviors. Short-term sleep deprivation studies suggest that acute sleep deprivation increases BP.…”

INTRODUCTION:Obstructive sleep apnea (OSA) is associated with cardiovascular morbidity, including hypertension. Beyond the severity of nocturnal hypoxia, other factors such as metabolic abnormalities but also sedentary behaviors and insufficient physical activity may contribute to elevated blood pressure (BP). To clarify the respective role of these factors as determinants of BP in OSA patients, we examined the relationship between BP and anthropometrics, severity of sleep apnea, and objectively measured physical activity and sedentary behaviors. METHODS: Ninetyfive adults presenting with OSA (apnea-hypopnea index > 10 events/h) and high cardiovascular risk (63.3 ؎ 8.8 y; body mass index: 29.9 ؎ 4.9 kg/m 2 ; apnea-hypopnea index: 41.3 ؎ 17.5/h; cardiovascular risk score: 13.5 ؎ 3.7%) were included. Physical activity and sedentary behaviors were objectively assessed by actigraphy, and self-measured home BP monitoring was measured. Logistic regression models adjusted for sex, age, and body mass index were built to identify the predictors of self-measured morning and evening BP. RESULTS: Physical activity was significantly related to obesity but not to the severity of sleep apnea or sleepiness. Sedentary behaviors were associated with self-measured morning and evening systolic BP (r ‫؍‬ 0.32, P ‫؍‬ .002; r ‫؍‬ 0.29, P ‫؍‬ .004). Steps per day were inversely associated with evening BP (r ‫؍‬ ؊0.27, P ‫؍‬ .01). Univariate analysis identified steps/d and time spent in vigorous physical activity as determinants for evening self-measured BP. In multivariate analysis, only steps/d were identified as a significant determinant of evening BP. CONCLUSIONS: Physical activity is the major determinant for evening BP in adults with OSA presenting high cardiovascular risk. Our results emphasize the need for lifestyle counseling programs in combination with CPAP to encourage regular physical activity in OSA subjects to obtain better BP control.

“…To our knowledge, there was one study done in mild OSA patients only (Przybylowski et al, 2007), while the present study and other studies were conducted in severe or moderate to severe OSA patients (Cintra et al, 2009;Vanhecke et al, 2008). This discrepancy is probably due to differences in the severity of OSA patients included in each study.…”
