Obstructive Sleep Apnea Is Associated with Newly Diagnosed Gestational Diabetes Mellitus

Abstract Context: Questionnaire studies linked symptoms of obstructive sleep apnea (OSA) to the risk of gestational diabetes mellitus (GDM). Whether this association is present when OSA is assessed objectively by polysomnography is not known. Objective: The objective of the study was to assess the relationship between pregnancy, OSA, and GDM. Design, Setting, and Participants: We conducted observational case-control studies using polysomnography in 15 nonpregnant, nondiabetic women (NP-NGT), 15 pregnant women with normal glucose tolerance (P-NGT), and 15 pregnant women with GDM (P-GDM). The groups were frequency matched for age and race/ethnicity. Pregnant women were studied during the late second to early third trimester. Main Outcome Measures: Comparisons of OSA diagnosis and sleep parameters between NP-NGT and P-NGT to assess the impact of pregnancy and between P-NGT and P-GDM to explore the association between GDM and OSA were measured. Results: Compared with NP-NGT, P-NGT women had a higher apnea hypopnea index (AHI) (median 2.0 vs 0.5, P = .03) and more disrupted sleep as reflected by a higher wake time after sleep onset (median 66 vs 21 min, P < .01) and a higher microarousal index (median 16.4 vs 10.6, P = .01). Among the pregnant women, P-GDM had markedly lower total sleep time (median 397 vs 464 min, P = .02) and a higher AHI (median 8.2 vs 2.0, P = .05) than P-NGT women. OSA was more prevalent in P-GDM than in P-NGT women (73% vs 27%, P = .01). After adjustment for prepregnancy body mass index, the diagnosis of GDM was associated with a diagnosis of OSA [odds ratio 6.60 (95% confidence interval 1.15–37.96)]. In pregnancy, after adjusting for prepregnancy body mass index, higher microarousal index significantly associated with higher hemoglobin A1c and fasting glucose levels. Higher oxygen desaturation index was associated with higher fasting glucose levels. Conclusion: Pregnancy is associated with sleep disturbances. Sleep is more disturbed in GDM than in P-NGT women. There is a strong association between GDM and OSA.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): Ministry of Health Czech Republic; identification of organization 65269705 Background Although continuous positive airway pressure (CPAP) is currently still the gold standard for therapy of moderate to severe obstructive sleep apnea (OSA), another alternative or adjunct effective therapeutic options exist. Lifestyle intervention focused on nutrition and weight reduction, regular exercise, sleep hygiene, smoking and alcohol restriction represents a recommended therapeutic strategy for OSA. Though this intervention represents an effective tool for improving objective and subjective parameters of OSA, it’s effectivity depends on components of the intervention, OSA severity and gender. Comprehensive remotely-supervised cardiac rehabilitation (CR) represents possible training intervention in home conditions using elements of telemedicine. Purpose This prospective study aims to investigate the feasibility and effect of a remotely-supervised CR in patients with newly diagnosed OSA with Apnea-Hypopnea Index greater than 15 episodes per hour. Methods This monocentric study is designed as a prospective, parallel, randomised, controlled trial of remotely-supervised 12-week CR in male patients between 40-60 years old with newly diagnosed OSA indicated to CPAP therapy. The sample size is calculated by 0,05 level of significance and 80% statistical power on 25 participants in each group. The Intervention group will undergo comprehensive remotely-supervised CR in home conditions with teleconsultation (contains telecoaching, telemonitoring) via regular phone calls and e-mails at least 1-2 times a week. The intervention will include nutrition, health-related lifestyle and behavioral changes recommendations, and at least 5 times a week 30 minutes of moderate-intensity aerobic training, 10 minutes of inspiratory and expiratory muscle training with breathing device and 10 minutes of oropharyngeal exercise along with individually titrated CPAP therapy. The control group will undergo individually titrated CPAP therapy only. The participants in both groups will go through the following assessments before and after this study: polysomnography, spirometry, anthropometry and body composition examination, laboratory values examination, quality of life questionnaires, Epworth sleepiness scale, 6-min walking test. Conclusions: Comprehensive remotely-supervised CR, as mentioned in this study, may represent an adjunct therapy with a promising future in patients with OSA. The study is occupied with a current issue and can also bring new possibilities and experiences in remote rehabilitation.

Objective: The aim of this research was to assess the relationship between prevalence and severity of obstructive sleep apnea (OSA) and insulin resistance among patients with increased risk of OSA without diabetes mellitus. Method and materials: our study group involved 102 individuals with suspected OSA, mean age 53.02 ± 12.37 years. Data on medical history, medication usage, sleep habits, sleep quality and daytime sleepiness, were obtained using questionnaires. All patients underwent standardized full night polysomnography. Serum fasting insulin and glucose concentration were analyzed, the homeostatic model assessment-insulin resistance (HOMA-IR) index was calculated. Results: polysomnographic study indicated that in the group with OSA mean values of apnea–hypopnea index (AHI), oxygen desaturation index (ODI), duration of SpO2 < 90% and average desaturation drop were significantly higher compared to the group without OSA, while the minimum SpO2 was significantly lower. The carbohydrate metabolism parameters did not differ within those groups. Significantly higher fasting insulin concentration and HOMA-IR index were found in the group with AHI ≥ 15 compared to the group with AHI < 15 and in the group with AHI ≥ 30 compared to the group with AHI < 30. Higher AHI and ODI were independent risk factors for higher fasting insulin concentration and higher HOMA-IR index. Increased duration of SpO2 < 90% was an independent risk factor for higher fasting glucose concentration. Conclusions: Individuals with moderate to severe OSA without diabetes mellitus had a higher prevalence of insulin resistance.
