Study population
Participation in the present study was proposed to all patients admitted over a 6-month period—from January to June 2007—to the Department of Diabetology at our hospital with poorly controlled type 2 diabetes, as assessed by one hospital staff doctor during an outpatients visit. The diabetic patients found to be poorly controlled (based on clinical and biological data) were hospitalized for an average of 1 to 5 days for various clinical examinations and patient education.

Results
A total of 362 patients with type 2 diabetes were hospitalized during the study period because of poor diabetic control, of which 23 (6%) had already been diagnosed with sleep apnoea. Thirty-two patients fulfilled the exclusion criteria and were excluded. Also, in four cases, it was impossible to analyze the polygraphy due to technical failure. The remaining 303 patients (156 men, 147 women) were finally included in the study.
The prevalence of newly diagnosed SAS was 63% (191/303) in these
Discussion
In the present study, we systematically performed nocturnal respiratory polygraphic studies in 303 patients consecutively admitted to hospital because of poorly controlled type 2 diabetes. We found that the prevalence of previously undiagnosed SAS was high in these patients, reaching 63%. Also, nearly all of the apnoeic patients had the obstructive form of the condition, whereas the prevalence of obstructive SAS in the general population is much lower, ranging from 2 to 9% [16]. In addition,

It should be noted that in those studies, neither the definitions of DPN and DN were uniform nor correlations between nocturnal hypoxemia parameters and diabetic microvascular complications were consistent [15–21]. Previous reports have revealed that OSA was especially prevalent among hospitalized patients with T2DM with a proportion of more than 60% [22,23].

2020, Diabetes Research and Clinical PracticeCitation Excerpt :Forty-one articles (n = 41) presented results of the prevalence of different sleep disorders in patients with diabetes (Fig. 2). The majority of studies measured the prevalence of sleep apnea disorders in diabetes (n = 25) [16–40], followed by restless leg syndrome (n = 11) [10,41–50], and periodic limb movement (n = 2) [51,52]. Three studies (n = 3) [52–54] did not specify the type of sleep disorder.
