Sleep quality and sex-related factors in adult patients with immune-mediated diabetes: a large cross-sectional study

Aim To analyze sleep quality and its relationships with clinical and biochemical features in a large cohort of adults with autoimmune diabetes. Methods We administered to 553 patients with autoimmune diabetes the questionnaires: Pittsburgh Sleep Quality Index (PSQI), diabetes distress scale, diabetes-related quality of life and diabetes treatment satisfaction questionnaire. We excluded patients with missing HbA1c ± 4 months from PSQI administration or incorrect PSQI compilation ( n = 110). Results Altered sleep quality was recorded in 142/443 subjects (32%), insufficient total sleep time in 177/443 (40%). The altered sleep quality group had higher HbA1c (median 56 mmol/mol [interquartile range-IQR 49–62] vs 59 [IQR 52–68]; P
