Exploring the Connection between Sleep Disorders, Emotional Distress, and Quality of Life in Functional Dyspepsia

Objective: This study aimed to explore the factors influencing sleep disorders in patients with functional dyspepsia. Methods: A total of 100 patients with functional dyspepsia admitted to Gong An County People's Hospital from 2020 to 2021 were selected. According to the Pittsburgh Sleep Quality Index (PSQI), those with a score >= 8 were classified as the occurrence group, whereas those with a score <8 were classified as the non-occurrence group. Clinical and disease characteristics of patients were collected. Logistic regression analysis was used to identify influencing factors. The emotional distress and quality of life of patients with different severities of sleep disorders were compared. Pearson's correlation was used to identify the relationship between the degree of sleep disorders and various indicators. Results: Out of 100 patients with functional dyspepsia, 58 (58.00%) had varying degrees of sleep disturbance. Logistic regression analysis showed that factors measured by the Self-Rating Anxiety Scale (SAS) (odds ratio [OR] = 3.088, p = 0.007), Self-Rating Depression Scale (SDS) (OR = 3.268, p = 0.005), Perceived Stress Scale (PSS) (OR = 2.659, p = 0.019), and Functional Digestive Disorders Quality of Life (FDDQL) questionnaire (OR = 2.591, p = 0.022) were the main factors influencing sleep disturbance. Pearson correlation analysis suggested that SAS (r = 0.677, p < 0.001), SDS (r = 0.623, p < 0.001), and PSS (r = 0.550, p < 0.001) scores were positively correlated with the severity of sleep disturbance, whereas FDDQL (r = -0.623, p < 0.001) score was negatively correlated with the severity of sleep disturbance. Conclusion: Functional dyspepsia patients are prone to varying degrees of sleep disorders, which are closely related to emotional distress and quality of life. Clinical interventions can be developed in advance to stabilize patient emotions and improve their quality of life.
