Sleep Apnea, Sleep Quality and Hypertension in Patients with Type 2 Diabetes

Introduction and Aims
In the last years, there has been increasing interest on possible association between the sleep apnea with hypertension and
poor sleep quality in patients with glucose metabolism disorders. The present study aimed to assess the relationship between
sleep apnea, hypertension and sleep quality in patients with type 2 diabetes.
Materials and Methods
This descriptive - analytic study was carried out on 100 type 2 diabetes patients’ referral to the Saghez city diabetes unit
with convenience sampling. Data were gathered using Berlin Questionnaire and Pittsburgh Sleep Quality Index. Data were
analyzed using descriptive statistical testes, independent T test and Chi-square test.
Results
The results of this study showed 46 % of samples complained from sleep apnea and 42 % complained from poor sleep quality.
Results
showed that there are statistically significant relationship between sleep apnea and high blood (CI95%
= 1.6-9.4, OR = 3.9, p < 0.002) and sleep quality (CI95% = 1-4.9, OR = 2.1, P=0.04).The risk of sleep apnea were 3.9
and 2.1 fold higher in patients with hypertension and poor sleep quality than those patients without normotensive
and good sleep quality.
Conclusion
Regarding to high prevalence of sleep apnea and relationship between this disorder and high blood pressure and sleep quality
in patients with diabetes, using of screening methods for diagnose of sleep apnea in diabetic patients is necessary.
