Figure 5 Association of abdominal pain/discomfort severity, and Zung self-rated anxiety and depression scale scores for patients with irritable bowel syndrome in each age group. A: Age 18-27 years; B: Age 28-37 years; C: Age 38-47 years; D: Age 48-57 years; E: Age 58-67 years; F: Age 68-75 years. A1 to F1, association of abdominal pain/discomfort with quality of life in each age group. Severity of abdominal pain/discomfort was negatively correlated with irritable bowel syndrome-specific quality of life questionnaire (IBS-QoL) scores in the 58-67-year and 68-75-year groups (P < 0.05), but there was no correlation in the 18-27-year, 28-37-year, 38-47-year or 48-57-year groups (P > 0.05); A2 to F2, association of Zung Self-Rated Depression Scale (SDS) scores with quality of life in each age group. SDS scores were negatively correlated with IBS-QoL scores in all age groups (P < 0.01); A3 to F3, association of Zung Self-Rated Anxiety Scale (SAS) scores with quality of life in each age group. SAS scores were negatively correlated with IBS-QoL scores in all age groups (P < 0.01).
