Background Diabetes mellitus has many complications; hypoglycemia is one of them that is associated with severe signs and symptoms such as anxiety, psychosocial problems, and poor metabolic control. Objective This study aimed to investigate the factors affecting hypoglycemia fear in patients with type 2 diabetes. Methods The present descriptive-analytic study was conducted on 360 patients with type 2 diabetes referred to Velayat Hospital in Qazvin City, Iran, in 2017. The eligible samples were recruited through a convenience sampling method. The data collection instruments were a demographic checklist and the Hypoglycemia Fear Survey-II scale. The collected data were analyzed using descriptive tests, t-test, oneway ANOVA, the Pearson correlation, and regression analysis. Findings The Mean±SD age of the patients was 58.5±14.3 years, and the majority of them were women (65.3%). The Mean±SD score of hypoglycemia fear was 22.07±8.6 which was significant in terms of gender (P=0.002), type of treatment (P<0.001), employment (P=0.05), and educational status (P=0.05). The results of single-variable regression showed that the type of treatment (P<0.001), long-term complications (P=0.002), and gender (P=0.002) were associated with hypoglycemia fear. Also, the results of simultaneous regression showed that the type of treatment was associated with hypoglycemia fear (P<0.001). Conclusion The results of this study showed that the type of treatment was the most effective factor in hypoglycemia fear. Using insulin to treat diabetes strongly affect the hypoglycemia fear; therefore, it is possible to reduce the hypoglycemia fear by appropriate patients' instructions on how to inject and monitor insulin.

Background. Fear of hypoglycemia can result in anxiety, stress, anger, depression and severe avoidance behaviors that it affects the sleep quality of diabetic patients. Therefore, the present study was conducted with the aim of investigating the relationship between fear of hypoglycemia and sleep quality among type 2 diabetic patients. Methods. The present cross-sectional study was conducted on 400 type 2 diabetic patients referred to endocrinology clinic of Velayat Hospital and Boali Hospital in Qazvin, in 2019. Data were collected using a checklist for demographic variables, the Fear of Hypoglycemia Survey (FHS-W), and the Pittsburgh sleep quality index (PSQI). Descriptive statistics and Spearman correlation test were performed for data analysis using SPSS v24. Results. In this study, the mean age of diabetic patients was 55.75 ± 10.31. The majority of the participants were female (n = 299, 74.8%) and were treated with oral anti-diabetic drugs (n = 174, 43.5%). The mean score of sleep quality in patients was 8.98 ± 3.64 and the fear of hypoglycemia was 21.27 ± 11.92. The results of this study showed that there was a significant relationship between the fear of hypoglycemia and the poor sleep quality among patients (P < 0.001, r = 0.305). Conclusion. The fear of hypoglycemia has a direct and significant relationship with poor sleep quality in diabetic patients; so that this fear reduces the quality of sleep in diabetic patients. Therefore, in order to provide adequate sleep to prevent inappropriate sleep complications, great attention should be paid to the issue of fear of hypoglycemia, and consider some actions to reduce this fear.

Introduction and Objective Fear of hypoglycemia can result in anxiety, stress, anger, depression and severe avoidance behaviors that it affects the sleep quality of diabetic patients. Therefore, the present study was conducted with the aim of investigating the relationship between fear of hypoglycemia and sleep quality among type II diabetic patients.
