Functional Gastrointestinal Disorders Common Among Nurses With Poor Sleep Quality in Shanghai, China: A Pilot Study.

This study aimed to determine whether functional gastrointestinal disorders are more common among nurses with self-reported poor sleep. In total, 468 nurses working the day shift or rotating shifts completed two questionnaires: the questionnaire for irritable bowel syndrome (IBS) using Rome III criteria and the Pittsburgh Sleep Quality Index (PSQI). The prevalence of poor sleep was 41.04% (95% confidence interval, CI: [36.23, 45.85]), and poor sleep was significantly more common among rotating-shift nurses than among day-shift nurses (50.70% vs. 29.95%; p < .05). Among nurses with poor sleep, the prevalence of IBS and functional constipation was 35.15% (95% CI: [27.86, 42.44]) and 11.52% (95% CI: [6.65, 16.39]), respectively. After adjusting for age, work schedule, night pain, and psychological factors, IBS (odds ratio, OR: 1.88; 95% CI: [1.03, 2.49]) and functional constipation (OR: 1.77; 95% CI: [0.64, 2.57]) were significantly more common in nurses with poor sleep. We conclude that IBS and functional constipation are prevalent in nurses with poor sleep. Poor sleep was independently associated with IBS and functional constipation among nurses in Shanghai, China.

[An epidemiologic study on functional constipation among adult communities in Shanghai].

OBJECTIVE: To determine the prevalence and risk factors of functional constipation (FC) by using Rome III criteria in the local adult communities. METHODS: A stratified randomized and community-based study by multi-stage cluster sampling was employed. A household survey was conducted from April to May 2010. All of the participants were interviewed face-to-face by filling out the self-administered questionnaires which based on Rome III criteria for the diagnosis of FC. Self-rating anxiety scale (SAS), self-rating depression scale (SDS) and Athens insomnia scale (AIS) were carried out to evaluate the psychological characteristics and qualities of sleep. RESULTS: A total of 7648 subjects fulfilled the questionnaires, with the response rate as 90.0%. 211 patients met the Rome III criteria, including 90 males and 121 females. The adjusted prevalence rates of FC were 2.5% in males, 3.3% in females and with an overall rate as 2.9%. The ratio of men to women was 1:1.32, with significant difference between males and females (P=0.043). The most common group was in the 18-29 year-olds (χ2=37.359, P=0.000). FC patients were more likely to be detected in the group with normal BMI (χ2=16.087, P=0.002), having received high education (χ2=27.604, P=0.000), being intelectuals (χ2=6.922, P=0.031) and divorced (χ2=22.000, P=0.000) than in other groups. Multivariate analysis showed that excessive intake of high-fat food was significantly associated with the presence of FC (odds ratio as 1.253, P=0.000), whereas foods with high-fiber (odds ratio as 0.854, P=0.029) might serve as protective factors. Significant differences between FC groups and control groups were found in the incidence of anxiety (with odds ratio as 2.583, P=0.000) and insomnia (odds ratio as 2.443, P=0.000). CONCLUSION: The prevalence of FC in adult communities in Shanghai Songjiang district was not higher than that in other parts of the communities. Excessive intake of high-fat food, anxiety and insomnia might be risk factors for FC and foods with high-fiber contents might serve as protective factors.

Functional gastrointestinal disorders among adolescents with poor sleep: a school-based study in Shanghai, China.

PURPOSE: This study aimed to determine whether functional gastrointestinal disorders are more common among adolescents with self-reported poor sleep. METHODS: Junior middle school and senior high school students (n = 1,362) were recruited from schools in Shanghai. Students completed two questionnaires: the questionnaire for irritable bowel syndrome (IBS) in adolescents and the Pittsburgh Sleep Quality Index. RESULTS: The prevalence of poor sleep was 34.29% [95% confidence interval (CI) = 31.77-36.81] and there was no significant difference between genders (P = 0.991). The tendency towards poor sleep increased with age, with age group yielding a significant effect (P = 0.001). In junior middle school and senior high school students, the propensity towards poor sleep was 30.10% (95% CI = 27.08-33.12%) and 42.11% (95% CI = 37.67-46.55%), respectively. Among students with poor sleep, the prevalence of IBS was 19.70% (95% CI = 16.09-23.31). After adjusting for age, sex, night pain, and psychological factors, IBS was significantly more common in students with poor sleep (odds ratio = 1.92; 95% CI = 1.07-2.58). CONCLUSION: We conclude that IBS is prevalent in students with poor sleep. Poor sleep was independently associated with IBS among adolescents in Shanghai China.

[Risk factors of irritable bowel syndrome in adolescents in China].

OBJECTIVE: To explore the risk factors for irritable bowel syndrome (IBS) among school adolescents in China. METHOD: A stratified, randomized study by cluster sampling was conducted, which recruited 51,956 students from high and primary schools in Chinese cities. All students were requested to fill in a questionnaire. RESULT: (1) Factors including class (odds ratio 1.12), excessive intake of pepper (odds ratio 1.17), fried (odds ratio 1.08) and starch-based foods (odds ratio 1.06), gastrointestinal tract infection (odds ratio 2.66), abuse of analgesic (odds ratio 1.49), inheritance (odds ratio 1.83), fatigue (odds ratio 1.32) and repression (odds ratio 1.45) were significantly associated with the presence of IBS (P < 0.05). High protein food (odds ratio 0.90) was a protective factor. CONCLUSION: Different food intake, gastrointestinal tract infection, abuse of analgesic, inheritance and psychological factors might be related to development of IBS in the students of the cities involved in this study.

[An epidemiologic study of functional bowel disorders in adolescents in China].

OBJECTIVE: To explore the most common bowel frequency and the prevalence rates of functional bowel disorders among adolescents in China. METHODS: A questionnaire survey was conducted among 51,956 students from high and primary schools in 6 Chinese cities distributed in the whole China collected by stratified, randomized, cluster sampling to study the epidemiology of functional bowel disorders. RESULTS: (1) 88.05% +/- 0.28% of the students had bowel frequency between 1 - 2 times/day and 1 time/two days. Girl students were found to have a lower bowel frequency than boy students (P < 0.01). (2) The prevalence rates of irritable bowel syndrome, chronic constipation, and chronic diarrhea were 20.19% (10 490), 25.92% (13 467), and 8.77% (4557) respectively. CONCLUSION: (1) The normal bowel frequency among adolescents in China may be defined as bowel movements between 1 - 2 times per day and 1 time per two days. (2) Irritable bowel syndrome, chronic constipation and chronic diarrhea are common disorders among the adolescents in China.

OBJECTIVE: To explore the prevalence of irritable bowel syndrome (IBS) and its distribution characteristics among adolescents in China. METHODS: A stratified and randomized study by cluster sampling was employed, the study recruited 51 956 students from high and primary schools in different Chinese cities. All students were requested to fill in a questionnaire. RESULTS: The prevalence of IBS in China was 53.5% according to the Manning criterion and 20.2% according to the Rome II criterion. The prevalence in male and female students showed no significant difference (P>0.05), but there was higher prevalence of IBS in high school students. The prevalence of IBS was 53.3% according to the Manning criterion and 19.6% according to the Rome II criterion in south China. The prevalence of IBS was 51.2% according to the Manning criterion and 18.9% according to the Rome II criterion in North China. The prevalence of IBS was 58.0% according to the Manning criterion and 23.4% according to the Rome II criterion in west China. CONCLUSION: IBS is a common disorder among the adolescents and the prevalence of IBS is increasing with increase of age in adolescents.
