Investigation of the effect of the treatment applied to type 2 diabetes patients in the COVID-19 pandemic process on sleep quality, nutritional habits and biochemical parameters

Restrictions made during the COVID-19 pandemic process have affected the nutritional habits and sleep quality of individuals. This study was conducted to evaluate the sleep quality and nutritional habits of individuals diagnosed with type 2 diabetes during the COVID-19 pandemic process, and to investigate the effect of sleep quality and nutritional habits on biochemical parameters. It was carried out with 94 volunteers between the ages of 35 and 75 who were diagnosed with type 2 diabetes, who applied to the Endocrine and Metabolism and Internal Diseases outpatient clinic of Biruni University Hospital in Istanbul between December 2020 and February 2021. In this study; A questionnaire form including information about the sociodemographic characteristics, eating habits, pandemic process of the individuals, Pittsburgh Sleep Quality Index (PSQI), and food consumption frequency form were applied to the individuals. Anthropometric measurements and biochemical findings of the individuals were also taken. In accordance with the COVID-19 measures, the surveys were administered by phone calls or as an online google questionnaire in line with the consent of the individuals. The SPSS 15.0 statistical package program was used in Windows environment to evaluate all the obtained information together. When the data of individuals with an average age of 55.7±10.52 during the COVID-19 pandemic process were evaluated; 24.4% of them have good sleep quality and 75.5% have bad sleep quality. It was determined that the consumption frequencies of "Milk-Yoghurt", "Sausage-Sausage, etc.", "Fish" and "Spices" of the individuals had a statistically significant difference on sleep quality (p<0.005). According to the sleep quality evaluation results, it was concluded that the biochemical parameters of vitamin D and magnesium were lower in individuals with poor sleep quality. As a result; studies should be conducted on a larger sample of the relationship between sleep quality and dietary habits in individuals diagnosed with diabetes. Key words: COVID-19, type 2 diabetes, nutrition, sleep quality.
