OBJECTIVETo investigate the prevalence of functional dyspepsia (FD) and the psychological disorders in Chinese population and their relation.

METHODSA total of 1016 apparently healthy people (study population) randomly selected from population were interviewed. A general questionnaire, Zung self-rating depression scales (SDS), and anxiety scales (SAS) were given to each subject. Seventy-two inpatients with confirmed diagnosis of FD, 84 with organic dyspepsia, and 197 with other organic diseases were also studied.

RESULTSAmong the study population, 23.5% had FD and 9. 1% had disturbances of depression and/or anxiety. The prevalence of psychological disturbances in FD group (15.5%) differed significantly from that in non-FD group (7.1%, P < 0.01 ) . In the survey of inpatients, the rate of depression/anxiety in FD group (54.2%) was greater than that in organic dyspepsia group (19.0%) and other organic diseases group (28.9%), P < 0.05, and was also significantly higher than that of the FD cases in the study population (15.5%), P < 0.01. Further analysis showed that some psychosocial disturbances were risk factors of FD.

CONCLUSIONBoth FD and depression/anxiety disturbances are common in China, and there is a link between them.

BACKGROUND/AIMS: Migraine is frequently accompanied by symptoms consistent with functional gastrointestinal disorders (FGIDs). This study evaluated the prevalence of functional gastrointestinal symptoms and assessed the symptoms' relationship with the concomitant functional symptoms of anxiety, depression, and headache-related disability. METHODS: This prospective study included 109 patients with migraine who were recruited from a headache clinic at a teaching hospital. The participants completed a self-administered survey that collected information on headache characteristics, functional gastrointestinal symptoms (using Rome III criteria to classify FGID), anxiety, depression, and headache-related disability. RESULTS: In total, 71% of patients met the Rome III criteria for at least one FGID. In patients with FGID, irritable bowel syndrome was the most common symptom (40.4%), followed by nausea and vomiting syndrome (24.8%) and functional dyspepsia (23.9%). Depression and anxiety scores were significantly higher in patients meeting the criteria for any FGID. The number of the symptoms consistent with FGID in individual patients correlated positively with depression and anxiety. CONCLUSIONS: FGID symptoms defined by the Rome III criteria are highly prevalent in migraine. These symptoms correlate with psychological comorbidities, such as depression and anxiety.

Disturbances in biological rhythms could lead to unfavorable health impact. This study aimed to evaluate the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS) in rotating shift workers, and to determine the factors that have significant association with the prevalence of FD and IBS. The research had been carried out among nurses and nursing assistants working at Ewha Womans University Mokdong Hospital between December 2010 and February 2011. The subjects completed self-reported questionnaires, including the quality of the sleep and the level of stress. The prevalence of FD and IBS defined by ROME III criteria, and factors associated the disorders in rotating shift workers were compared with those of day workers. A total of 207 subjects were included in the study with 147 rotating shift workers (71.0%), and 60 (29.0%) day workers. The prevalence of IBS in rotating shift workers was higher than that in day workers (32.7% vs 16.7%, P = 0.026). However, no significant difference in the prevalence of FD was observed between the two groups (19.7% vs 20.0%, P = 0.964). In the multivariate analysis, the risk factors for IBS were rotating shift work (OR, 2.36; 95% CI, 1.01-5.47) and poor sleep quality (OR, 4.13; 95% CI, 1.82-9.40), and the risk factors for FD were poor sleep quality (OR, 2.31; 95% CI, 1.01-5.28), and severe stress (OR, 2.19; 95% CI, 1.06-4.76). A higher prevalence of IBS among rotating shift workers could be directly associated with the circadian rhythm disturbance. The circadian rhythm disturbance may be related with the pathogenesis of IBS.
