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

A Cross-Sectional Study of Sleep Disturbances in Children and Adolescents With Abdominal Pain-Associated Disorders of Gut-Brain Interaction

The aims of the current study were to determine the frequencies of specific sleep disturbances in youth with abdominal pain-associated disorders of gut-brain interaction (AP-DGBIs) and to assess relationships with psychological dysfunction. This was a retrospective evaluation of 226 consecutive patients diagnosed with an AP-DGBI. All had undergone a systematic evaluation of gastrointestinal symptoms, the Sleep Disturbance Scale for Children, and the Behavior Assessment System for Children. Disorders of initiation and maintenance of sleep (DIMS; 40%) and disorders of excessive daytime somnolence (DOES; 14%) were each present in more than 10% of the patients. Both DIMS and DOES scores were more likely to be elevated in patients with anxiety and/or depression scores in the at-risk or elevated-risk ranges. Sleep disorders are common in youth with AP-DGBIs and are associated with anxiety and depression, even in those patients with anxiety and depression in the at-risk range.

Association between sleep disorders and constipation Risk: A systematic review and Meta-Analysis

OBJECTIVES

The objective of this study was to evaluate the potential relationship between sleep disturbances and various types of constipation in patients.

METHODS

We conducted systematic searches in the research databases PubMed, EMBASE, Web of Science, and Cochrane Library to identify qualifying studies. Using Stata software version 14.0, we calculated the Odds Ratio (OR) and 95 % confidence interval (CI) for constipation in patients with sleep disorders. If P > 0.1 and I2 ≤ 50 %, we employed a fixed-effects model; otherwise, we applied a random-effects model. We assessed publication bias using funnel plots and Egger's test.

RESULT

The pooled analysis demonstrated that individuals with sleep disorders were associated with an increased risk of all-cause constipation (OR = 1.47; 95 %CI: 1.31-1.64; I2 = 88.8 %, P＜0.001). Specifically, both children (OR = 1.29; 95 %CI: 1.16-1.42; I2 = 63.8 %, P＜0.001) and adults (OR = 1.65; 95 %CI: 1.39-1.97; I2 = 92.4 %, P＜0.001) with a history of sleep disorders exhibited an increased risk of all-cause constipation.. Furthermore, patients with a history of insufficient sleep were also associated with an increased risk of constipation (OR = 1.33; 95 %CI: 1.20-1.46; I2 = 6.7 %, P＜0.001). Additionally, patients with poor sleep quality were found to have an increased risk of constipation (OR = 1.56; 95 %CI: 1.0-2.45; I2 = 90.9 %, P = 0.05). Lastly, patients with insomnia were found to have the highest risk of constipation (OR = 1.94; 95 %CI: 1.37-2.76; I2 = 97.8 %, P＜0.001).

CONCLUSION

This meta-analysis indicates that sleep disorders are associated with an elevated risk of constipation. Insomnia, poor sleep quality, and insufficient sleep duration all contribute to elevating the risk of constipation. These findings emphasize the significance of recognizing sleep disorders as an independent risk factor for constipation in both children and adults.

Long-term gastrointestinal symptoms and sleep quality sequelae in adolescents after COVID-19: a retrospective study

Objective

To evaluate the long-term gastrointestinal (GI) symptoms and sleep quality sequelae in adolescents with COVID-19.

Methods

Between June and July 2023, an online survey was done in Xiaoshan District, Hangzhou City, Zhejiang Province, China, using the GI Symptom Rating Scale (GSRS) and the Pittsburgh Sleep Quality Inventory (PSQI).

Results

GI symptoms in COVID-19 patients increased by 11.86% compared to before infection, while sleep quality decreased by 10.9%. Over time, there was a significant increase in the cumulative incidence rate of GI symptoms and sleep disorders (p < 0.001). Follow-up of COVID-19 positive patients within 6 months of infection showed that GI symptoms and sleep quality began to ease starting from the first month after infection. Further analysis indicated a significant linear relationship between the severity of GI symptoms and sleep quality (R > 0.5, p < 0.001). Moreover, females, older age, and higher education were identified as risk factors influencing the long-term effects of COVID-19.

Conclusion

SARS-CoV-2 affects GI symptoms and sleep quality in adolescents during both the acute phase and post-infection periods. Over time, these symptoms gradually alleviate. A significant correlation exists between GI symptoms and sleep quality.

Prevalence and determinants of constipation in children in Asia: a systematic review and meta-analysis

Background

Constipation is prevalent worldwide, significantly increasing healthcare costs and diminishing the quality of life in children affected. Current studies have yielded mixed results regarding the factors associated with constipation, and mainly focusing on patients outside of Asia. Moreover, most of these studies lack focus on the paediatric population. This study aimed to identify the prevalence and associated factors of constipation among children in Asia.

Methods

In this systematic review and meta-analysis, we systematically searched PubMed, Scopus, and Cochrane for cohort and cross-sectional studies published from database inception up to October 12, 2022, and continued with manual searching until September 2, 2023. Eligible studies were those that included children in Asia aged 0-18 years old suffering from idiopathic constipation, with prevalence value provided in the English abstract. The analysis included clinical and general population. Children with organic constipation, who had undergone gastrointestinal surgery, or with congenital defects were excluded, as these factors affect the incidence of constipation. Data included in the analysis were extracted from published reports only. The extracted data were pooled using random-effects model to analyse the prevalence of constipation in children in Asia. This study is registered with PROSPERO, CRD42022367122.

Findings

Out of 4410 systematically searched studies and 36 manually searched ones, a total of 50 studies were included in the final analysis, encompassing data from 311,660 children residing in Asia. The pooled prevalence of constipation was 12.0% (95% CI 9.3-14.6%, I2 = 99.8%). There was no significant difference in constipation prevalence observed by sex and geographical location. Nonetheless, adolescents and children aged 1-9 years exhibited a significantly higher prevalence constipation compared to infants (p < 0.0001) Additionally, significant differences in constipation rates were observed across various diagnostic methods, population sources, and mental health conditions.

Interpretation

Despite the high heterogeneity resulting from varying diagnostic tools or definitions used among studies, our review adds to the literature on constipation among children in Asia. It reveals a notably high prevalence of constipation in this demographic. Diagnostic methods, age, and compromised mental health emerged as significant influencers of constipation among children in Asia, highlighting potential strategies to mitigate constipation prevalence in children in Asia.

Sleep Problems in Pediatric Disorders of Gut-Brain Interaction: A Systematic Review

OBJECTIVE

Disorders of gut-brain interaction (DGBIs) are common, and findings are mixed on rates of sleep problems (e.g., sleep quality) in pediatric populations. A clear understanding of sleep problems in pediatric DGBIs is needed as sleep challenges might negatively impact symptoms and prognoses. The aims of this systematic review are to (1) describe the prevalence and types of sleep problems in pediatric patients with DGBIs and examine differences by DGBI diagnosis and (2) examine the relationship among sleep problems and pain, mood, and functional outcomes in pediatric patients with DGBIs.

METHODS

We searched PubMed, PsycInfo, CINAHL, and Medline in June 2022; articles were included if they enrolled ≤19 years old with a DGBI, used a quantitative assessment of sleep problems, and were available in English. The Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies was used to assess study quality. We used a protocol to systematically pull and tabulate data across articles with quality assessment ratings.

RESULTS

Twenty-four articles with 110,864 participants across 9 countries were included, with most studies being of moderate to weak quality. Patients with DGBIs reported more sleep problems than healthy peers, and some research reviewed found that patients with IBS had more sleep problems than other DGBI diagnoses. Sleep problems in DGBIs were related to worse mood, pain, and functional outcomes.

CONCLUSION

Pediatric patients with DGBIs are experiencing sleep problems that can impact outcomes. Screening for sleep problems and targeted treatment is needed to best support these patients.

Prevalence and Influencing Factors of Irritable Bowel Syndrome in Medical Staff: A Meta-Analysis

BACKGROUND

Irritable bowel syndrome (IBS) is a common functional digestive tract disease worldwide, with a high prevalence among medical staff. The purpose of this study is to systematically evaluate the prevalence and influencing factors of IBS in medical staff.

METHODS

We searched English online databases, including PubMed, The Cochrane Library, Web of Science, Embase, and EBSCOhost. The retrieval time was from database establishment to May of 2021. We screened the literature according to inclusion and exclusion criteria, extracted the relevant information, and evaluated the research quality. A meta-analysis was performed using the Stata 16.0 and Review Manager 5.4.1 software.

RESULTS

A total of 11 English studies from seven countries were included in this study, including 3,360 medical staff. The results of the meta-analysis showed an overall prevalence of IBS among medical staff of 16% [95%CI (0.15 ~ 0.17)] and that shift work (OR 2.27)), poor sleep quality (OR 4.27), and female gender (OR 2.29) are the major influencing factors of medical staff suffering from IBS.

CONCLUSIONS

The prevalence of irritable bowel syndrome among medical staff is relatively high, and hospitals can start by looking for targeted interventions from the highly related factors of IBS among medical staff such as shift work patterns, females, and poor sleep quality.

Association between multiple sleep dimensions and functional bowel disorders among Chinese college freshmen

BACKGROUND

Although sleep disorder is thought as a risk factor for functional bowel disorders, its impact role in adolescents remains unknown and the contribution of different sleep dimensions may deserve further attention. This study aimed to evaluate the relationship between multiple sleep dimensions and functional bowel disorders among Chinese college freshmen.

METHODS

A cross-sectional survey was conducted in college freshmen from Huazhong University of Science and Technology in Wuhan, China in September 2019 with random cluster sampling method. All participants completed questionnaires about living habits, sleep and digestive symptoms. Diagnosis of irritable bowel syndrome and functional constipation were based on the Rome IV criteria. Univariate and multivariate logistic regression models were applied to assess the association of sleep dimensions with irritable bowel syndrome or functional constipation.

RESULTS

Based on the 3335 individuals who completed the questionnaire, the overall prevalence of irritable bowel syndrome and functional constipation in college freshmen were 2.5% and 1.7%, respectively. Multivariate analysis revealed that compared with individuals reporting good sleep quality, those reporting poor (OR = 7.269, 95%CI: 2.876-18.370) were associated with increased risk of irritable bowel syndrome. Similarly, those reporting fair (OR = 2.068, 95%CI: 1.010-4.236) and poor (OR = 5.664, 95%CI: 1.864-17.205) were associated with increased risk of functional constipation. There was no statistically significant association between other sleep dimensions (sleep duration, sleep timing, or sleep latency) and irritable bowel syndrome or functional constipation.

CONCLUSION

Self-reported poor sleep quality was a stronger independent predictor of functional bowel disorders than other sleep dimensions among Chinese college freshmen. Future intervention studies should consider the role of sleep quality for the prevention of FBDs in adolescents.

Depressive Symptoms, Sleep Quality and Diet During the 2019 Novel Coronavirus Epidemic in China: A Survey of Medical Students

The psychological condition of medical students may be influenced by the 2019 novel coronavirus (COVID-19) outbreak. This study investigated the prevalence and influencing factors of depressive symptoms, poor sleep quality and poor diet in students at Kunming Medical University during the early part of the COVID-19 outbreak. A cross-sectional study was used from a questionnaire survey in February 2020. Of a total of 1,026 study participants, the prevalence of depressive symptoms, poor sleep quality, and poor diet was, respectively, 22.4, 33.2, and 17.4%. Male students and students with a low degree of focus on COVID-19 had a high risk of depressive symptoms. A high percentage of females and students in the fifth grade, as well as students with high levels of concern about the negative impact of COVID-19 on their education or employment, comprised those with poor sleep quality. Students in the fifth grade and students with high levels of concern about the negative impact of COVID-19 on their education or employment were more likely to report poor diet. This study suggests the importance of monitoring medical students' depressive state during the COVID-19 outbreak, and universities are encouraged to institute policies and programs to provide educational counseling and psychological support to help students to cope with these problems.

Parental, Perinatal, and Childhood Risk Factors for Development of Irritable Bowel Syndrome: A Systematic Review

Background/Aims

Adverse early life experiences are associated with the development of stroke, cancer, diabetes, and chronic respiratory and ischemic heart diseases. These negative experiences may also play a role in the development of irritable bowel syndrome (IBS)--a functional gastrointestinal disease. This review discusses the research to date on the parental, perinatal, and childhood risk and protective factors associated with the development of IBS.

Methods

A literature search was completed for studies published between 1966 and 2018 that investigated premorbid factors occurring during the perinatal and childhood periods as well as parental factors that were associated with the development of IBS.

Results

Twenty-seven studies fulfilled the review criteria. Risk factors that appeared in more than one study included: (1) parental IBS, substance abuse, parental punishment, and rejection as parental risk factors; (2) low birth weight as a perinatal risk factor; and (3) crowded living conditions in low-income families, childhood anxiety, depression, or child abuse as childhood risk factors. Protective factors for IBS were emotional warmth from the parents and being born to an older mother.

Conclusions

More effort is needed to identify what fetal and maternal factors are associated with low birth weight and IBS. A well-executed prospective birth cohort with a collection of bio-samples and functional data will provide a better understanding of how adversity and the interplay between genetics, epigenetics, and numerous risk factors affect the development of IBS.

Sleep and Gastrointestinal Symptoms in a Community-Based Survey of Children

We examined whether gastrointestinal (GI) symptoms were associated with sleep disturbances in a community-based sample of 337 school-aged children from Ypsilanti, Michigan. Parents completed the sleep-related breathing disorder scale of the Pediatric Sleep Questionnaire and the Conners' parents rating scale, which included questions concerning GI symptoms. One fifth of the children screened positive for sleep-disordered breathing; the same fraction had sleepiness, and one-quarter snored more than half the time. Similarly, one quarter of children had 2 or more GI symptoms. Children with positive sleep-disordered breathing scores were 2.22 times as likely to have 2 or more GI symptoms in the past month after confounder adjustment (95% confidence interval = 1.39-3.55). In particular, this relationship appeared to be driven by daytime sleepiness, as children with sleepiness had about a 2-fold higher prevalence of 2 or more GI symptoms (adjusted prevalence ratio = 1.96, 95% confidence interval = 1.18-3.26). Neither snoring nor sleep duration were associated with GI symptoms.

Stress and sleep quality in doctors working on-call shifts are associated with functional gastrointestinal disorders

AIM

To investigate the role of sleep quality and psychosocial problems as predictors of functional gastrointestinal disorders (FGIDs) in doctors that work 24 hour-on-call shifts.

METHODS

In this cross-sectional observation study, using the Rome III Questionnaire and Pittsburgh Sleep Quality Index (PSQI), we analyzed 170 doctors with 24 hour-on-call shifts.

RESULTS

Among the participants that had experienced a 24 hour-on-call shift within the last 6 mo, 48 (28.2%) had FGIDs. Overall prevalence of irritable bowel syndrome (IBS) and functional dyspepsia (FD) were 16.5% and 17.1%, respectively, with 5.3% exhibiting both. Sleep scores (PSQI) (8.79 ± 2.71 vs 7.30 ± 3.43, P = 0.008), the presence of serious psychosocial alarm (83.3% vs 56.6%, P = 0.004), and the proportion of doctors who experienced over two months of recent on-call work (81.2% vs 68.9%, P = 0.044) were significantly different between individuals with or without FGIDs. Multivariate analysis revealed that presenting serious psychosocial alarm was an independent risk factor for prevalence of FD (OR = 5.47, 95%CI: 1.06-28.15, P = 0.042) and poor sleep quality (PSQI ≥ 6) was a predictor of IBS (OR = 4.17, 95%CI: 1.92-19.02, P = 0.016).

CONCLUSION

Physicians should recognize the role of sleep impairment and psychological stress in the development of FGIDs and a comprehensive approach should be considered to manage patients with FGIDs.

Sleep problems and pain: a longitudinal cohort study in emerging adults

Sleep and pain are thought to be bidirectional related on a daily basis in adolescents with chronic pain complaints. In addition, sleep problems have been shown to predict the long-term onset of musculoskeletal pain in middle-aged adults. Yet, the long-term effects of sleep problems on pain duration and different types of pain severity in emerging adults (age: 18-25) are unknown. This study investigated the cross-sectional and longitudinal relationship between sleep problems and chronic pain, and musculoskeletal pain, headache, and abdominal pain severity in a general population of emerging adults. We studied whether these relationships were moderated by sex and whether symptoms of anxiety and depression, fatigue, or physical inactivity mediated these effects. Data of participants from the longitudinal Dutch TRacking Adolescents' Individual Lives Survey were used. Follow-up data were collected in 1753 participants who participated in the fourth (N = 1668, mean age: 19.0 years [SD = 0.6]) and/or fifth (N = 1501, mean age: 22.3 years [SD = 0.6]) assessment wave. Autoregressive cross-lagged models were used for analyses. Sleep problems were associated with chronic pain, musculoskeletal pain, headache and abdominal pain severity, and predicted chronic pain and an increase in musculoskeletal pain severity at 3 years of follow-up. This prospective effect was stronger in females than in males and was mediated by fatigue but not by symptoms of anxiety and depression or physical inactivity. Only abdominal pain had a small long-term effect on sleep problems. Our results suggest that sleep problems may be an additional target for treatment in female emerging adults with musculoskeletal pain complaints.

Association between Diet and Lifestyle Habits and Irritable Bowel Syndrome: A Case-Control Study

Background/Aims

Recent papers have highlighted the role of diet and lifestyle habits in irritable bowel syndrome (IBS), but very few population-based studies have evaluated this association in developing countries. The aim of this study was to evaluate the association between diet and lifestyle habits and IBS.

Methods

A food frequency and lifestyle habits questionnaire was used to record the diet and lifestyle habits of 78 IBS subjects and 79 healthy subjects. Cross-tabulation analysis and logistic regression were used to reveal any association among lifestyle habits, eating habits, food consumption frequency, and other associated conditions.

Results

The results from logistic regression analysis indicated that IBS was associated with irregular eating (odds ratio [OR], 3.257), physical inactivity (OR, 3.588), and good quality sleep (OR, 0.132). IBS subjects ate fruit (OR, 3.082) vegetables (OR, 3.778), and legumes (OR, 2.111) and drank tea (OR, 2.221) significantly more frequently than the control subjects. After adjusting for age and sex, irregular eating (OR, 3.963), physical inactivity (OR, 6.297), eating vegetables (OR, 7.904), legumes (OR, 2.674), drinking tea (OR, 3.421) and good quality sleep (OR, 0.054) were independent predictors of IBS.

Conclusions

This study reveals a possible association between diet and lifestyle habits and IBS.

Epidemiology of irritable bowel syndrome in children and adolescents in Asia

OBJECTIVES

Several cross-sectional surveys have been conducted to study the prevalence of irritable bowel syndrome (IBS) in children. The aim of the present study was to conduct a systematic review and a meta-analysis of published literature to estimate the prevalence of IBS among Asian children.

METHOD

A computer-assisted search of MEDLINE, EMBASE, PsycINFO, and regional databases of Asia was carried out. Selected articles were reviewed in depth and data were extracted. Pooled prevalence, sex differences, and 95% confidence intervals were calculated. Heterogeneity of the studies was assessed using the I(2) test.

RESULTS

A total of 16 cross-sectional studies that reported prevalence of IBS (in children and adolescents) and qualified to be included were taken into the final analysis containing 38,076 patients. Selected studies are from China, Korea, Japan, Iran, Sri Lanka, and Saudi Arabia. Studies showed a marked heterogeneity with I(2) of 98.59 (P < 0.0001). Prevalence of IBS ranges from 2.8% to 25.7%, with a pooled prevalence of 12.41% (95% confidence interval 9.87-14.95). Prevalence risk ratio of girl:boy is 1.39. Prevalence of subtypes is diverse and varies between studies.

CONCLUSIONS

The published data indicate that IBS is a significant problem among Asian children and adolescents. Female sex predisposes children and adolescents to develop IBS.

Epidemiology of pediatric functional abdominal pain disorders: a meta-analysis

Objective

We aimed to review the literature regarding epidemiology of functional abdominal pain disorders in children and to assess its geographic, gender and age distribution including associated risk factors of developing functional abdominal pain.

Methods

The Cochrane Library, MEDLINE, EMBASE, CINAHL and PsychInfo databases were systematically searched up to February 2014. Study selection criteria included: (1) studies of birth cohort, school based or general population samples (2) containing data concerning epidemiology, prevalence or incidence (3) of children aged 4-18 years (4) suffering from functional abdominal pain. Quality of studies was rated by a self-made assessment tool. A random-effect meta-analysis model was used to estimate the prevalence of functional abdominal pain in childhood.

Results

A total of 58 articles, including 196,472 children were included. Worldwide pooled prevalence for functional abdominal pain disorders was 13.5% (95% CI 11.8-15.3), of which irritable bowel syndrome was reported most frequently (8.8%, 95% CI 6.2-11.9). The prevalence across studies ranged widely from 1.6% to 41.2%. Higher pooled prevalence rates were reported in South America (16.8%) and Asia (16.5%) compared to Europe (10.5%). And a higher pooled prevalence was reported when using the Rome III criteria (16.4%, 95% CI 13.5-19.4). Functional abdominal pain disorders are shown to occur significantly more in girls (15.9% vs. 11.5%, pooled OR 1.5) and is associated with the presence of anxiety and depressive disorders, stress and traumatic life events.

Conclusion

Functional abdominal pain disorders are a common problem worldwide with irritable bowel syndrome as most encountered abdominal pain-related functional gastrointestinal disorder. Female gender, psychological disorders, stress and traumatic life events affect prevalence.

A school-based study of irritable bowel syndrome in medical students in beijing, china: prevalence and some related factors

Purpose. To investigate the prevalence and some related factors about irritable bowel syndrome (IBS) in medical students. Methods. A cross-sectional study was carried out from February 2014 to Jun 2014 in Beijing University of Chinese Medicine, Beijing, China. All participants were asked to completed self-administered questionnaires. Results. Seven hundred and sixty-seven medical students (23.26 ± 2.88 years, 25.6% males) completed the survey. The prevalence of IBS was 33.3%, with a high prevalence in women (36.1%). Among the IBS patients, 112 cases were IBS-M (43.9%) and 77.6% had moderately severe IBS. There were no statistical differences between control group and IBS patients in anxiety and depression scores (P > 0.05). The total score of Pittsburgh sleep quality index (PSQI) was significantly higher for medical students with IBS and 35.5% of IBS patients had severe sleep disorder; the scores of child trauma questionnaire (CTQ) and student-life stress inventory (SLSI) were also higher in IBS patients. Sex and sleep disorder were independently associated with IBS (OR, 1.914, 95%CI, 1.281-2.860; OR, 1.143, 95%CI, 1.074-1.216). Conclusion. Our study has many valuable findings and they may provide valuable suggestions for the necessary intervention and treatment measures towards medical students.
