Sleep Hygiene Education in Type 2 Diabetes

The aim of this study is to evaluate the effect of sleep hygiene education on sleep quality and glycemic control of Type 2 Diabetes patients. Patients between the ages of 18-65, who were registered to the Gaziemir 11 No. Dokuz Eylül Education Family Health Centers and applied to the polyclinic, and had Type 2 Diabetes diagnosis for at least 1 year were included in the study. In the patient group in which the study will be conducted, the patients who will be applied the Pittsburgh Sleep Quality Index (PSQI) and those with a PSQI score of more than 5 were included in the study. A sociodemographic questionnaire was applied to the participants, the last measured HbA1c values were questioned, and fingertip fasting blood sugars were measured. Sleep hygiene training was applied to the intervention group at the first admission, a sleep hygiene rules checklist was given and they were asked to keep a two-week sleep diary. After the two-week sleep diary, the participants in the intervention group were given training on these issues by determining the things that could impair the quality of their sleep through the sleep diary they kept. Sleep training and sleep hygiene rules checklist were given to the control group after three months of follow-up. At the end of the 3-month follow-up, PSQI was applied to both groups again, and the last measured HbA1c values were recorded and fingertip fasting blood glucose was measured.

Treatment and study plan

Sleep Hygiene Education

Behavioral

Participants in this arm receive a structured sleep hygiene education program in addition to usual diabetes care. The education includes guidance on sleep-wake routines, sleep environment optimization, caffeine and screen use reduction, and behavioral strategies to improve sleep quality. The intervention is delivered through standardized educational sessions and written materials.

Primary outcomes

  1. Change in Sleep Quality (Pittsburgh Sleep Quality Index, PSQI)

    Time frame: 3 Months

    Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). The primary endpoint is the change in PSQI total score from baseline to post-intervention (end of follow-up), with lower scores indicating better sleep quality.

Secondary outcomes

  1. Change in Glycemic Control (HbA1c)

    Time frame: 3 Months

    Glycemic control will be assessed using glycated hemoglobin (HbA1c, %). The secondary outcome is the change in HbA1c levels from baseline to post-intervention (end of follow-up).
