Abstract: Objective: To investigate the status of the impaired awareness of hypoglycemia (IAH) in patients with type 2 diabetes Mellitus(T2DM) and its relationship with the risk of hypoglycemia. Methods: A total of 650 patients who were adopted by convenience sampling were investigated by using general data questionnaire, hypoglycemia perception impairment(Gold’s), and Chinese version of hypoglycemia fear questionnaire-anxiety scale. SPSS 21.0 was used for statistical analysis of the data. Results: The prevalence of IAH in T2DM patients was 13.7%. HbA1c(<7%), fear of hypoglycemia(>0 point), frequency of hypoglycemia in recent years(≥5 times), history of asymptomatic hypoglycemia and severe hypoglycemia were independently correlation factors(All P<0.05). Conclusion: In clinical practice, it is necessary to conduct IAH assessment to timely identify high-risk groups of hypoglycemia, so as to strengthen targeted management to avoid the occurrence of severe hypoglycemia.
