There is little epidemiological research on Irritable bowel syndrome (IBS) in Inner Mongolia, China. Here we investigated the prevalence of IBS and factors associated with IBS in both males and females in Inner Mongolia Medical University by a cross-sectional study. We recruited Inner Mongolia Medical University students residing in campus and asked them to complete a self-administered questionnaire. The prevalence of IBS in each factor we chose in all, male, and female students was determined. We assessed IBS subtypes in male and female students. Multivariate logistic regression models were used to assess the factors associated with IBS in male and female students. The overall prevalence of IBS was 29.5%. The prevalence of IBS in female students was significantly higher than that in male students (31.3% vs. 24.8%, p < .001). Logistic regression results showed that attempting to lose weight and anxiety were both associated with increasing odds of IBS, while exercise was not associated with IBS in either male or female students. In female students, snack consumption and depression were also both associated with increasing odds of IBS. The predominant IBS subtype was the diarrhea-predominant type in both male and female students. Considering the high prevalence of IBS in students and the fact that the factors associated with IBS can be improved by individuals, students should be given adequate education and counseling to improve their mental health and lifestyle, especially female students in higher grades. 相似文献
Objective: The study aimed to develop a predictive model of how Type D personality influences health behaviours, social support and symptom severity and assess its generalisability to a range of chronic illnesses.
Design: Participants were classified as either healthy (n = 182) or having a chronic illness (n = 207). Participants completed an online survey measuring Type D and a range of health-related variables. Chronic illness participants were classified as having either a functional somatic syndrome (i.e. chronic fatigue syndrome or fibromyalgia), where the underlying pathological processes were unclear, or illnesses such as type 2 diabetes, osteoarthritis or rheumatoid arthritis, where the causes are well understood.
Main Outcome Measures: Outcome measures were health behaviours, social support and both physical and psychological symptoms.
Results: The rate of Type D was higher in chronic illness participants (53%) than in healthy controls (39%). Negative affectivity (NA) and social inhibition (SI) both correlated with outcome measures, although NA was generally the stronger predictor. Using NA and SI as independent subscales led to superior prediction of health outcomes than using categorical or continuous representations.
Conclusion: Findings suggest that the relationship between Type D and health outcomes may generalise across different chronic illnesses. 相似文献
Night eating syndrome (NES) is characterized by excessive evening and/or nocturnal eating episodes. Studies indicate an attentional bias towards food in other eating disorders. For NES, however, evidence of attentional food processing is lacking. Attention towards food and non-food stimuli was compared using eye-tracking in 19 participants with NES and 19 matched controls without eating disorders during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in initial fixation position or gaze duration. However, a significant orienting bias to food compared to non-food was found within the NES group, but not in controls. A significant attentional maintenance bias to non-food compared to food was found in both groups. Detection times did not differ between groups in the search task. Only in NES, attention to and faster detection of non-food stimuli were related to higher BMI and more evening eating episodes. The results might indicate an attentional approach-avoidance pattern towards food in NES. However, further studies should clarify the implications of attentional mechanisms for the etiology and maintenance of NES. 相似文献
Patients with chronic fatigue syndrome (CFS) frequently report chronic pain symptoms. Cognitive behavioural therapy (CBT) for CFS results in a reduction of fatigue, but is not aimed at pain symptoms. In this study, we tested the hypothesis that a successful treatment of CFS can also lead to a reduction of pain. The second objective was to explore possible mechanisms of changes in pain. The third objective was to assess the predictive value of pain for treatment outcome. Data from two previous CBT studies were used, one of adult CFS patients (n=96) and one of adolescent CFS patients (n=32). Pain severity was assessed with a daily self-observation list at baseline and post-treatment. The location of pain in adults was assessed with the McGill Pain Questionnaire (MPQ). Patients were divided into recovered and non-recovered groups. Recovery was defined as reaching a post-treatment level of fatigue within normal range. Recovered adult and adolescent CFS patients reported a significant reduction of pain severity compared to non-recovered patients. Recovered adult patients also had fewer pain locations following treatment. The decrease in fatigue predicted the change in pain severity. In adult patients, a higher pain severity at baseline was associated with a negative treatment outcome. 相似文献
