ABSTRACT
OBJECTIVE: To explore the relationship between chronic complications of type 2 diabetes mellitus(T2 DM)and obstructive sleep apnea syndrome(OSAS). METHODS: The data of 153 hospitalized T2 DM patients aged 40-65 years were collected; the demograhic data was recorded, biochemical indicators were recorded and analyzed, and the patients were screened for chronic complications of diabetes and OSAS. The patients with ketosis, acidosis and infection, and those who were addicted to alcohol,smoking or drug or with mental illness, or severe organ dysfunction were excluded.According to whether OSAS was combined, they were divided into the OSAS group and the control group were divided into groups. The differences in the incidence of chronic complications between the two groups were compared.Spearman correlation analysis was used to determine the relationship between chronic complications and OSAS.RESULTS: The incidence of diabetic peripheral neuropathy(DPN)in the OSAS group was higher than in the control group(45% vs. 26.9%, P=0.017). The incidence of coronary heart disease was significantly higher in the OSAS group than in the control group(20% vs. 8.6%, P=0.038). The differences were statistically significant.Spearman correlation analysis showed that OSAS was positively correlated with diabetic peripheral neuropathy(P=0.021)and coronary heart disease(P=0.041). CONCLUSION: OSAS may be associated with peripheral neuropathy and coronary heart disease in patients with T2 DM.
