The relationship between abdominal pain and emotional wellbeing in children and adolescents in the Raine Study

Breaking the cycle: Psychological and social dimensions of pediatric functional gastrointestinal disorders

BACKGROUND

Functional gastrointestinal disorders (FGIDs) in children present with chronic symptoms like abdominal pain, diarrhea, and constipation without identifiable structural abnormalities. These disorders are closely linked to gut-brain axis dysfunction, altered gut microbiota, and psychosocial stress, leading to psychiatric comorbidities such as anxiety, depression, and behavioral issues. Understanding this bidirectional relationship is crucial for developing effective, holistic management strategies that address physical and mental health.

AIM

To examine the psychiatric impacts of FGIDs in children, focusing on anxiety and depression and their association with other neurodevelopmental disorders of childhood, such as attention-deficit/hyperactivity disorder, emphasizing the role of the gut-brain axis, emotional dysregulation, and psychosocial stress. Key mechanisms explored include neurotransmitter dysregulation, microbiota imbalance, central sensitization, heightening stress reactivity, emotional dysregulation, and symptom perception. The review also evaluates the role of family dynamics and coping strategies in exacerbating FGID symptoms and contributing to psychiatric conditions.

METHODS

A narrative review was conducted using 328 studies sourced from PubMed, Scopus, and Google Scholar, covering research published over the past 20 years. Inclusion criteria focused on studies examining FGID diagnosis, gut-brain mechanisms, psychiatric comorbidities, and psychosocial factors in pediatric populations. FGIDs commonly affecting children, including functional constipation, abdominal pain, irritable bowel syndrome, gastroesophageal reflux, and cyclic vomiting syndrome, were analyzed concerning their psychological impacts.

RESULTS

The review highlights a strong connection between FGIDs and psychiatric symptoms, mediated by gut-brain axis dysfunction, dysregulated microbiota, and central sensitization. These physiological disruptions increase children’s vulnerability to anxiety and depression, while psychosocial factors - such as chronic stress, early-life trauma, maladaptive family dynamics, and ineffective coping strategies - intensify the cycle of gastrointestinal and emotional distress.

CONCLUSION

Effective management of FGIDs requires a biopsychosocial approach integrating medical, psychological, and dietary interventions. Parental education, early intervention, and multidisciplinary care coordination are critical in mitigating long-term psychological impacts and improving both gastrointestinal and mental health outcomes in children with FGIDs.

Acid reflux medication use among adults with depressive symptoms

Emotional stress, including depression, may contribute to increased gastroesophageal reflux disease symptoms. In this paper, we aim to evaluate the associations between depressive symptoms, depressive symptom severity, and symptom clusters with acid reflux medication use, considering the potential interaction effect of sex. Data from the 2007-2018 National Health and Nutrition Examination Survey were used. Participants aged 18 years or older were included if they responded to the depressive symptoms and prescription medication questionnaires. This study included 31,444 participants, of whom 2871 had depressive symptoms. Participants with depressive symptoms had significantly higher odds of using antacids (aOR = 1.735; p < 0.001), histamine-2 receptor antagonists (H2RAs) (aOR = 1.653; p < 0.001), and proton pump inhibitors (PPIs) (aOR = 1.723; p < 0.001). A positive association was also found between depressive symptom severity and the use of antacids (aOR = 1.054; p < 0.001), H2RAs (aOR = 1.048; p < 0.001), and PPIs (aOR = 1.053; p < 0.001). Moreover, increases in cognitive-affective and somatic scores were associated with higher odds of using antacids (aOR = 1.080 for cognitive, 1.102 for somatic; p < 0.001), H2RAs (aOR = 1.078 for cognitive, 1.083 for somatic; p < 0.001), and PPIs (aOR = 1.075 for cognitive, 1.105 for somatic; p < 0.001). No significant sex interaction effects were observed. Adjusted models demonstrated no significant associations between depressive symptoms and the duration of medication use. This study provides evidence of an association between depressive symptoms and acid reflux medication use, highlighting the need to screen for related symptoms in patients with depressive symptoms.

The effects of autistic traits in adolescents on the efficacy of paediatric Intensive Interdisciplinary Pain Treatment (IIPT)

Autistic adolescents are at greater risk of chronic pain, but it is unclear how autistic features may relate to individual aspects of chronic pain. As autism traits exist in the general population as well, it is important to know if autistic traits could impact how effective chronic pain management is for adolescents. Here we examined autistic traits in 112 patients (12-18yrs) recruited from a UK national specialist adolescent pain rehabilitation programme. Participants completed screening questionnaires for autistic traits upon entry to the programme, as well as clinically recognised pain measures before and after the 3-week treatment program. Autistic traits predicted greater psychological challenges at treatment onset. Critically, autistic traits were not related to the magnitude of improvement in pain measures during the pain management program. Our study suggests that adolescents with greater autistic traits may benefit from existing pain rehabilitation programs at similar rates to their peers. Additionally, these data suggest no reason for therapeutic pessimism for autistic pain patients. We do however acknowledge that these data may differ in populations with an autistic diagnosis, and that barriers may still exist for autistic people in treatment for pain. PERSPECTIVE: Autistic traits were explored in patients undergoing an Intensive Interdisciplinary Pain Treatment (IIPT). Higher autistic traits correlated with more pain related psychological difficulties at intake. Autistic traits were not related to the magnitude of improvement following IIPT. Our data therefore suggests that autism should not be a barrier to IIPT. DATA AVAILABILITY: Data is held in the PAIRED Pain Rehabilitation Database: Bath and Bristol, individual data used in the current analyses are therefore not available.

Recurrent abdominal pain in children in Wuhu, China was not associated with Helicobacter pylori infection, but associated with <1 h/day physical activity and academic stress

Background

Recurrent abdominal pain (RAP) is one of the most common gastrointestinal disorders in children. The aim of this study was to investigate the relationship between RAP and Helicobacter pylori infection in children in Wuhu, China as well as the risk factors for Helicobacter pylori infection in this region.

Materials and methods

In this cross-sectional survey, we randomly selected children aged 6-17 years who underwent health examinations at three public hospital examination centers in Wuhu city, Anhui Province, China. Helicobacter pylori infection was assessed by a 13C-urea breath test (UBT) kit. Questionnaires were custom designed to obtain data on behavioral, sociodemographic, and environmental characteristics, and to investigate the relationship between RAP and Helicobacter pylori infection in children.

Results

A total of 1,187 children aged 6-17 years were enrolled, among these children, 182 were diagnosed with RAP, with an incidence rate of 15.3%. A total of 266 children were infected with Helicobacter pylori, with an infection rate of 22.4%. Multivariate regression analysis revealed that physical activity for <1 h/day and academic stress are associated with RAP in children, whereas Helicobacter pylori infection, age, sex, body mass index (BMI), and fast-food consumption are not associated with RAP in children. Our research also found that the risk of Helicobacter pylori infection increases with age in children. Risk factors for Helicobacter pylori infection in children include left-behind children, poor hygiene habits, family history of Helicobacter pylori infection, and mother with low cultural levels.

Conclusions

Recurrent abdominal pain in children in Wuhu, China was not associated with Helicobacter pylori infection, but strongly associated with <1 h/day physical activity and academic stress.

The prevalence of chronic pain in children and adolescents: a systematic review update and meta-analysis

ABSTRACT

Chronic pain, defined as persistent or recurring pain or pain lasting longer than 3 months, is a common childhood problem. The objective of this study was to conduct an updated systematic review and meta-analysis on the prevalence of chronic pain (ie, overall, headache, abdominal pain, back pain, musculoskeletal pain, multisite/general pain, and other) in children and adolescents. EMBASE, PubMed, CINAHL, and PsycINFO were searched for publications between January 1, 2009, and June 30, 2023. Studies reporting population-based estimates of chronic nondisease related pain prevalence in children or adolescents (age ≤ 19 years) were included. Two independent reviewers screened articles based on a priori protocol. One hundred nineteen studies with a total of 1,043,878 children (52.0% female, mean age 13.4 years [SD 2.4]) were included. Seventy different countries were represented, with the highest number of data points of prevalence estimates coming from Finland and Germany (n = 19 each, 4.3%). The overall prevalence of chronic pain in children and adolescents was 20.8%, with the highest prevalence for headache and musculoskeletal pain (25.7%). Overall, and for all types of pain except for back pain and musculoskeletal pain, there were significant differences in the prevalence between boys and girls, with girls having a higher prevalence of pain. There was high heterogeneity (I 2 99.9%). Overall risk of bias was low to moderate. In summary, approximately 1 in 5 children and adolescents experience chronic pain and prevalence varies by pain type; for most types, there is higher pain prevalence among girls than among boys. Findings echo and expand upon the systematic review conducted in 2011.

Development and Evaluation of the Abdominal Pain Knowledge Questionnaire (A-PKQ) for Children and Their Parents

BACKGROUND

Abdominal pain is a common and often debilitating issue for children and adolescents. In many cases, it is not caused by a specific somatic condition but rather emerges from a complex interplay of bio-psycho-social factors, leading to functional abdominal pain (FAP). Given the complex nature of FAP, understanding its origins and how to effectively manage this condition is crucial. Until now, however, no questionnaire exists that targets knowledge in this specific domain. To address this, the Abdominal Pain Knowledge Questionnaire (A-PKQ) was developed.

METHODS

Two versions were created (one for children and one for parents) and tested in four gastroenterology clinics and one specialized pain clinic in Germany between November 2021 and February 2024. Children between 8 and 17 years of age (N = 128) and their accompanying parents (N = 131) participated in the study. Rasch analysis was used to test the performance of both versions of the questionnaire.

RESULTS

The original questionnaires exhibited good model and item fit. Subsequently, both questionnaires were refined to improve usability, resulting in final versions containing 10 items each. These final versions also demonstrated good model and item fit, with items assessing a variety of relevant domains.

CONCLUSION

The A-PKQ is an important contribution to improving assessment in clinical trials focused on pediatric functional abdominal pain.

The relationship of depressive symptoms with pain and analgesic use in Turkish adolescents

PROBLEM

This study aimed to determine the prevalence of depressive symptoms, pain (headache, abdominal pain, back pain) and analgesic use among Turkish adolescents. Additionally, it aimed to examine the association between depressive symptoms and pain and analgesic use in adolescents.

METHODS

This cross-sectional, correlational study was conducted in Izmir, Turkey with 954 adolescents aged 11-19 years. Data were collected with the "socio-demographic questionnaires" and the "Center for Epidemiologic Studies Depression Scale for Children". Analyzes were performed using descriptive statistics and multiple logistic regression analysis.

FINDINGS

Of the adolescents, 632 (66.2%) showed depressive symptoms. Of the adolescents, 424 (44.4%) experienced headache, 256 (26.8%) experienced abdominal pain, and 343 (36.0%) experienced back pain. A total of 309 (32.4%) adolescents used analgesics for headaches, 132 (13.8%) abdominal pain, and 47 (4.9%) for back pain. Female gender, high level maternal education, bad economic status, poor health perception, bad school success, pain and analgesic use were the correlated variables with adolescent depression.

CONCLUSIONS

The depressive symptoms, headache and back pain, and use of analgesics especially for headaches were common among adolescents. The results showed depression in adolescent correlated with pain (headache, abdominal pain, and back pain) and analgesic use. Regular screening is needed to assure early intervention of depression among adolescents.

Bullying Involvement and Physical Pain Between Ages 10 and 13 Years: Reported History and Quantitative Sensory Testing in a Population-Based Cohort

We aimed to quantify the prospective association between bullying and physical pain in a population-based cohort of adolescents. We assessed 4,049 participants of the 10 and 13 years waves of the Generation XXI birth cohort study in Portugal. Pain history was collected using the Luebeck pain screening questionnaire. A subsample of 1,727 adolescents underwent computerized cuff pressure algometry to estimate pain detection/tolerance thresholds, temporal pain summation and conditioned pain modulation. Participants completed the Bully Scale Survey and were classified as "victim only", "both victim and aggressor", "aggressor only", or "not involved". Associations were quantified using Poisson or linear regression, adjusted for sex and adverse childhood experiences. When compared to adolescents "not involved", participants classified as "victim only" or "both victim and aggressor" at age 10 had higher risk of pain with psychosocial triggers, pain that led to skipping leisure activities, multisite pain, pain of higher intensity, and pain of longer duration, with relative risks between 1.21 (95% confidence interval: .99, 1.49) and 2.17 (1.57, 3.01). "Victims only" at age 10 had lower average pain detection and tolerance thresholds at 13 years (linear regression coefficients: -1.81 [-3.29, -.33] and -2.73 [-5.17, -.29] kPa, respectively), as well as higher pain intensity ratings (.37 [.07, .68] and .39 [.06, .72] mm), when compared with adolescents not involved. No differences were seen for the remaining bullying profiles or sensory measures. Our findings suggest that bullying may have long-term influence on the risk of chronic musculoskeletal pain and may interfere with responses to painful stimuli. PERSPECTIVE: We found prospective evidence that bullying victimization in youth: 1) is more likely to lead to negative reported pain experiences than the reverse, 2) may have long-term influence on adverse pain experiences, and 3) may contribute to pain phenotypes partly by interfering with somatosensory responses to painful stimuli.

Management of children with non-acute abdominal pain and diarrhea in Dutch primary care: a retrospective cohort study based on a routine primary care database (AHON)

OBJECTIVE

To describe the testing, prescription, referral, and follow-up management by general practitioners (GPs) for children presenting with non-acute abdominal pain and/or diarrhea in primary care.

DESIGN

Retrospective cohort study with one-year follow-up.

SETTING

Registry data from a Dutch primary care database (AHON) between 2015 and 2019.

SUBJECTS

Children aged 4-18 years old who presented by face-to-face consultation in primary care for non-acute abdominal pain and/or diarrhea (>7 days).

MAIN OUTCOME MEASURES

We recorded the proportions of children who received (1) diagnostic testing, medicine prescriptions, follow-up consultations, and referrals at their first visit and (2) repeat consultations and referrals by one-year of follow-up.

RESULTS

Among the 2200 children (median age, 10.5 years; interquartile range, 7.0-14.6) presenting to a GP with non-acute abdominal pain and/or diarrhea, most reported abdominal pain (78.7%). At the first visit, GPs performed diagnostic testing for 32.2%, provided a prescription to 34.5%, and referred 2.5% to secondary care. Twenty-five percent of the children had a follow-up consultation within four weeks and 20.8% had a repeat consultation between four weeks and one year. Thirteen percent of the children were referred to secondary care by one year. However, only 1% of all children had documentation of an organic diagnosis needing management in secondary care.

CONCLUSION

One-third of children received diagnostic testing or a medicine prescription. Few had a follow-up consultation and >10% was referred to pediatric care. Future research should explore the motivations of GPs why and which children receive diagnostic and medical interventions.

Recurrent headache, stomachache, and backpain among adolescents: association with exposure to bullying and parents' socioeconomic status

OBJECTIVES

Recurrent pain is a prevalent and severe public health problem among adolescents and is associated with several negative health outcomes. In a representative sample of adolescents this study examined 1) whether exposure to bullying and low socioeconomic status (SES) were associated with recurrent headache, stomachache and backpain, 2) the combined effect of exposure to bullying and low SES on recurrent pain and 3) whether SES modified the association between bullying and recurrent pain.

METHODS

Data derived from the Danish contribution to the international collaborative study Health Behaviour in School-aged Children (HBSC). The study population was students in three age groups, 11-, 13- and 15-year-olds from nationally representative samples of schools. We pooled participants from the surveys in 2010, 2014 and 2018, n=10,738.

RESULTS

The prevalence of recurrent pain defined as pain 'more than once a week' was high: 11.7 % reported recurrent headache, 6.1 % stomachache, and 12.1 % backpain. The proportion who reported at least one of these pains 'almost every day' was 9.8 %. Pain was significantly associated with exposure to bullying at school and low parental SES. The adjusted odds ratio (AOR, 95 % CI) for recurrent headache when exposed to both bullying and low SES was 2.69 (1.75-4.10). Equivalent estimates for recurrent stomachache were 5.80 (3.69-9.12), for backpain 3.79 (2.58-5.55), and for any recurrent pain 4.81 (3.25-7.11).

CONCLUSIONS

Recurrent pain increased with exposure to bullying in all socioeconomic strata. Students with double exposure, i.e., to bullying and low SES, had the highest OR for recurrent pain. SES did not modify the association between bullying and recurrent pain.

Qualitative study evaluating the expectations and experiences of Dutch parents of children with chronic gastrointestinal symptoms visiting their general practitioner

OBJECTIVES

Chronic gastrointestinal symptoms are common among children and affect their daily activities and quality of life. The majority will be diagnosed with a functional gastrointestinal disorder. Effective reassurance and education are, therefore, key components of the physician's management. Qualitative studies have shown how parents and children experience specialist paediatric care, yet less is known about general practitioners (GPs), who manage most cases in the Netherlands and have a more personal and enduring relationship with their patients. Therefore, this study evaluates the expectations and experiences of parents of children visiting a GP for chronic gastrointestinal symptoms.

DESIGN

We conducted a qualitative interview study. Online interviews were audio and video recorded, transcribed verbatim and independently analysed by the first two authors. Data were collected and analysed concurrently until data saturation was reached. Using thematic analysis, we developed a conceptual framework reflecting respondent expectations and experiences. We performed a member check of the interview synopsis and the conceptual framework.

SETTING

Dutch primary care.

PARTICIPANTS

We purposively sampled participants from a randomised controlled trial evaluating the effectiveness of faecal calprotectin testing in children with chronic gastrointestinal complaints in primary care. Thirteen parents and two children participated.

RESULTS

Three key themes emerged: disease burden, GP-patient relationship and reassurance. Often, the experienced disease burden and the pre-existing GP-patient relationship influenced expectations (eg, for further investigations or a sympathetic ear), and when a GP fulfilled these expectations, a trusting GP-patient relationship ensued that facilitated reassurance. We found that individual needs influenced these themes and their interrelationships.

CONCLUSION

Insights provided by this framework could help GPs managing children with chronic gastrointestinal symptoms in daily practice and may therewith improve the consultation experience for parents. Further research should evaluate whether this framework also holds true for children.

The Cost-Effectiveness of a Dance and Yoga Intervention for Girls with Functional Abdominal Pain Disorders

BACKGROUND

Functional abdominal pain disorders (FAPDs) affect children worldwide, being more prevalent among girls. The individual and societal burdens of the disease are substantial, and evidence-based interventions are needed. Non-pharmacological treatments have generally produced promising results, with dance and yoga specifically having potential as an effective treatment option. Beside efficacy, the cost-effectiveness of interventions is important when prioritizing and allocating public resources.

OBJECTIVE

This study evaluated the cost-effectiveness of an 8-month dance and yoga intervention for girls with functional abdominal pain or irritable bowel syndrome, based on a randomized control trial called 'Just in TIME'.

METHODS

The intervention, performed in Sweden, was studied using a decision analysis tool, i.e., a decision tree within the trial followed by a Markov model with a time horizon of 10 years. The base case considered healthcare costs as well as productivity losses, measuring the effects in gained quality-adjusted life-years (QALYs) and presenting an incremental cost-effectiveness ratio (ICER).

RESULTS

The base case results show that the intervention, compared with current practice, was the dominant strategy from both the 12-month and long-term perspectives. The sensitivity analyses indicated that the long-term, but not the short-term, findings were robust for different assumptions and changes in parameter estimates, resulting in ICERs similar to those of the base case scenario.

CONCLUSIONS

Offering dance and yoga to young girls with FAPDs generates small QALY gains and monetary savings compared with standard healthcare and is likely cost-effective. These findings make a valuable contribution to an area where evidence-based and cost-effective treatment interventions are needed.

Clinical Presentations of Teenage Outpatients Encountered by General Internists in Japanese Hospitals: A Cross-Sectional Study

Introduction General internists in Japanese hospitals sometimes consult on adolescents. Our university hospital encounters more adolescents with mental health complaints than other city hospitals. Consequently, based on our experience, we hypothesized that psychiatric disorders are significantly more common among teenagers who visit general internists. Therefore, we retrospectively analyzed the clinical profiles of teenage outpatients who visited general internists at three hospitals to test this hypothesis. Methods This study included 342 patients aged 13-19 years who visited the Departments of General Internal Medicine at Toyama University Hospital, Nanto Municipal Hospital, and Kamicichi General Hospital between January 2019 and December 2021. Data on age, sex, chief complaint, the period from onset to visit, referral status, and final diagnosis were collected from medical records. We also identified the final diagnoses of 1,375 outpatients from the university hospital during the same period, stratifying them by age. Multiple comparison analyses, Chi-squared tests, and residual analyses were performed to analyze the data. Results The number of psychiatric teen patients was significantly higher in the university hospital group than in the other city hospital groups (p<0.01). The incidence of psychiatric disorders, such as stress-related mental disorders, including adjustment and eating disorders (p<0.001), was also significantly higher in the teenage group (13-19 years) than in other age groups. Most psychiatric disorders lead to complaints of physical symptoms. Conclusions The potential onset of clinical episodes during consultations with teenage patients can make treating this age group more challenging; thus, they may require care at university hospitals. Furthermore, Japanese general internists in university hospitals encounter patients in their late teens with physical signs more often than in other hospitals. This trend may be unique to general medicine departments ("Sogo-Shinryo") in Japanese university hospitals. However, if general internists act under primary care principles, they can adequately assist adolescent patients.

Twenty-year Outcomes of a Pediatric Chronic Abdominal Pain Cohort: Early Adulthood Health Status and Offspring Physical and Behavioral Health

Chronic abdominal pain (CAP) represents a common pediatric primary pain disorder that can have long-term effects on physical and mental health into adulthood. Pediatric CAP and Control cohorts recruited in childhood (∼11 years old, T1) and then assessed in emerging adulthood (∼20 years old, T2) were evaluated again for health outcomes in early adulthood (∼30 years old, T3) for the current study. Further, the study evaluated the mental and physical health of offspring of participants who had become parents. Participants who agreed to enroll at T3 (CAP: n = 90, Control: n = 55) completed measures regarding current health, health-related quality of life (HRQoL), and their child's health when applicable. Results indicated close to 20% of the CAP cohort reported recurrent CAP across all 3 timepoints. Participants with current CAP reported poorer HRQoL compared to participants with remitted CAP who reported poorer HRQoL compared to Control participants. The CAP cohort reported higher health-related anxiety compared to the Control cohort regardless of current pain status. CAP compared to Control participants reported greater emotional problems and fewer conduct problems in their children. Longitudinal studies are needed to assess the developmental course of pediatric chronic pain and intergenerational pathways of risk and resilience. Perspective: This article evaluates patterns of chronic abdominal pain from childhood into early adulthood. Patients with pediatric chronic abdominal pain continue to present with health-related anxiety in adulthood and report greater emotional problems in offspring.

"A source of empowerment and well-being": Experiences of a dance and yoga intervention for young girls with functional abdominal pain disorders

Background

Functional abdominal pain disorders are common among children and adolescents worldwide and effective treatments are needed to alleviate suffering for these children and their families. This study aimed to explore the experience of participating in a combined dance and yoga intervention from the perspectives of girls aged 9-13 years with functional abdominal pain disorders.

Materials and Methods

A randomized controlled trial called Just in TIME (Try, Identify, Move and Enjoy) recruited 121 girls aged 9-13 years with functional abdominal pain disorders. The eight-month intervention combined dance and yoga twice a week, focusing on enjoyment, socialization and playful creativity in an undemanding and non-judgemental environment. The intervention group comprised 64 girls, of whom 25 were purposefully selected for this qualitative interview study. Semi-structured interviews were conducted and analysed using qualitative content analysis with an inductive approach.

Results

The girls' experiences of the Just in TIME intervention can be described as "A source of empowerment and well-being which facilitated personal growth and new ways of engaging in life". The main category was derived from six generic categories: "A sense of belonging", "Joy and emotional expression through movement", "Relief from pain", "More self-confident", "More active in daily life" and "A sense of calm."

Conclusions

Regular participation in an eight-month intervention with combined dance and yoga in a supportive and non-judgemental atmosphere can ease pain and strengthen inner resources, resulting in empowerment, well-being and a more active life for girls with functional abdominal pain disorders.

Trial registration

The Just in TIME study is available online at clinicaltrials.gov, ID: NCT02920268.

Next generation behavioral sequencing for advancing pain quantification

With symptoms such as spontaneous pain and pathologically heightened sensitivity to stimuli, chronic pain accounts for about 20% of physician visits and up to 2/3 of patients are dissatisfied with current treatments. Much of our knowledge on pain processing and analgesics has emerged from behavioral studies performed on animals presenting the same symptoms under pathological conditions. While humans can verbally describe their pain, studies on rodents have relied on behavioral assays providing non-exhaustive characterization or altering animals' original sensitivity through repetitive stimulations. The emergence of what we term "next-generation behavioral sequencing" is now permitting us to quantitatively describe behavioral features on millisecond to minutes long timescales that lie beyond easy detection with the unaided eye. Here, we summarize emerging videography and computational based behavioral approaches that have the potential to significantly improve pain research.

Risk Factors Associated With School Bullying Behaviors: A Chinese Adolescents Case-Control Study, 2019

This research aimed to identify risk factors including individual characteristics and environment circumstances related to different types of school bullying (physical, relational, verbal, sexual, and possession bullying) among middle school students in China. Cases were the respondents reporting perpetrating bullying behaviors three or more times in the past year. One control was selected for each case from those participants who were not involved in school bullying in the past 12 months. Data were collected between April 2019 and May 2019 in China. After considering potential confounding variables including gender, grade level, and school, multivariable conditional logistic regression analysis was performed based on the univariate logistic analysis including 1,594 adolescents. According to conditional logistic regression analysis, alcohol use and lack of emotional management and control were the significant individual characteristics positively associated with involvement in school bullying. Alcohol use was related to all five types of school bullying perpetration. Poor relationships between family members, father's alcohol use, and parental neglect were strong risk factors for relational bullying. Lack of a sense of safety and absence of trusted people were associated with physical, relational, and verbal bullying perpetration. Results of this study provide evidence about risk factors for school bullying and have implications for potential policies to reduce bullying. Effective policies and programs need to take individual characteristics (social-emotional skills, anger control), family (parent training in conflict resolution, appropriate disciplining), peer and school factors (promoting prosocial networks, zero tolerance for bullying, appropriate disciplining policies against students who bully others, teacher training on building positive teacher-student relationships and positive discipling techniques) into consideration in order to develop effective prevention programs.

Quantitative Assessment of Secondary Healthcare Utilisation by Patients With Functional Abdominal Pain

There is increasing awareness of the impact functional conditions have on the National Health Service (NHS). Less is known about the resources used to manage these conditions. This retrospective quantitative audit aims to determine the demographic and healthcare utilisation of functional abdominal pain patients presenting to the hospital. The most frequent hospital attenders with non-specific abdominal pain in NHS Grampian, 2018-2019, were assessed (n=144). Adult patients meeting the ROME II diagnostic criteria for functional abdominal pain diagnosis were included (n=33). Data were retrospectively collected manually from electronic medical records. Of 33 patients, 93.9% were female, with a mean age of 31.2 years. Each had accessed a mean of 11.5 specialist services, with 69.7% being referred to mental health services; 9.1% had completed treatment. Each patient had a median 4 (range 1-26) emergency/unscheduled presentations to hospital and median 2 (range 0-13) admissions for functional abdominal pain during the study period, with a total of 247 nights spent in hospital by this patient cohort for functional abdominal pain alone. The estimated total cost for these hospital admissions was £593,786.00. Extensive secondary-care input is currently required for patients with functional abdominal pain at a significant cost. Patients are re-presenting to the hospital frequently, which suggests that current management is not effective.

Saliva Cortisol in Girls With Functional Abdominal Pain Disorders: A Randomized Controlled Dance and Yoga Intervention

INTRODUCTION

Functional abdominal pain disorders (FAPDs) are common among girls and has been associated with stress. Cortisol is one of the major stress hormones. Dance and yoga have been shown to reduce abdominal pain among girls with FAPDs.

AIM

To investigate the effect of an 8-month intervention with dance and yoga on cortisol levels in saliva among girls with FAPDs.

METHODS

A total of 121 girls aged 9-13 years with irritable bowel syndrome (IBS) or functional abdominal pain were included in the study. Participants were randomized into an intervention group and a control group. The intervention group attended a combined dance and yoga session twice a week for 8 months. Saliva samples were collected during 1 day, in the morning and evening, at baseline, and at 4 and 8 months. Subjective pain and stress were assessed as well.

RESULTS

No significant effects on saliva cortisol levels between groups were observed after completion of the intervention at 8 months. However, evening cortisol and evening/morning quotient were significantly reduced at 4 months in the intervention group compared to the control group (p = 0.01, p = 0.004). There was no association between cortisol quota and pain or stress.

CONCLUSION

Improvements in cortisol levels were seen in the intervention group at 4 months but did not persist until the end of the study. This indicates that dance and yoga could have a stress-reducing effect during the ongoing intervention.

General practitioners' experiences with children and adolescents with functional gastro-intestinal disorders: a qualitative study in Norway

Objective: Functional gastrointestinal disorders (FGIDs) are common in children and adolescents. During 2016 and 2019, we investigated the experiences among parents of children with FGIDs and interviewed their children and adolescents during 2020. The aim of the present study was to explore the experiences among general practitioners (GPs) who treat this patient group.Design: Individual interviews with open-ended questions were audio recorded and transcribed, and subsequently analysed using descriptive content analysis.Setting: Urban and rural areas in two municipalities in Southern Norway. Participants: Twelve GPs practicing in the region were interviewed.Results: GPs generally feel competent treating these patients without referring them to hospital or specialists. Having known the patients and their families over time is important. Providing psycho-educational resources to the patients and parents is essential for their understanding that the pain is not dangerous. The importance of attending school was emphasised.Conclusions: The GPs' biopsychosocial focus and long-term follow-up care are essential in treating children and adolescents with FGIDs and their parents.KEY POINTSCurrent awarenessAbdominal pain is a common symptom in children and adolescents, for which an organic cause is seldom found.Main statementsGPs feel competent to treat children and adolescents who have functional gastro-intestinal disorders (FGIDs) without referring them to hospital or specialists. • A main task for GPs is to inform children, adolescents, and their parents that FGIDs are not a serious organic disease and that everyday life should continue.

Dance and yoga reduced functional abdominal pain in young girls: A randomized controlled trial

BACKGROUND

Functional abdominal pain disorders (FAPDs) affect children, especially girls, all over the world. The evidence for existing treatments is mixed, and effective accessible treatments are needed. Dance, a rhythmic cardio-respiratory activity, combined with yoga, which enhances relaxation and focus, may provide physiological and psychological benefits that could help to ease pain.

OBJECTIVES

The aim of this study was to evaluate the effect of a dance and yoga intervention on maximum abdominal pain in 9- to 13-year- old girls with FAPDs.

METHODS

This study was a prospective randomized controlled trial with 121 participants recruited from outpatient clinics as well as the general public. The intervention group participated in dance and yoga twice weekly for 8 months; controls received standard care. Abdominal pain, as scored on the Faces Pain Scale-Revised, was recorded in a pain diary. A linear mixed model was used to estimate the outcomes and effect sizes.

RESULTS

Dance and yoga were superior to standard health care alone, with a medium to high between-group effect size and significantly greater pain reduction (b = -1.29, p = 0.002) at the end of the intervention.

CONCLUSIONS

An intervention using dance and yoga is likely a feasible and beneficial complementary treatment to standard health care for 9- to 13-year-old girls with FAPDs.

SIGNIFICANCE

FAPDs affect children, especially girls, all over the world. The negative consequences such as absence from school, high consumption of medical care and depression pose a considerable burden on children and their families and effective treatments are needed. This is the first study examining a combined dance/yoga intervention for young girls with FAPDs and the result showed a reduction of abdominal pain. These findings contribute with new evidence in the field of managing FAPDs in a vulnerable target group.

Children's and adolescents' experiences with functional abdominal pain: a qualitative study in Norway

OBJECTIVE

Functional gastrointestinal disorders (FGIDs) are common during childhood and adolescence. When a somatic diagnosis is excluded, the healthcare system often terminates contact with the patient. The aim of the present study was to learn more about children's and adolescents' experiences with, and reflections on, the causes of their abdominal pain and what could possibly help them.

DESIGN

The study has a qualitative design. Interviews with open questions were carried out by the first author. The conversations were audiotaped, transcribed and analysed by means of qualitative content analysis.

SETTING

Children and adolescents referred from general practitioners located in urban and rural regions in two municipals in Norway. In 2016 and 2019, we had interviewed these children's parents about their child's abdominal pain. In spring 2020, the children and adolescents were interviewed.

PARTICIPANTS

Twelve children and adolescents aged 10-18 years with FGIDs.

RESULTS

Eight of the children and adolescents had recovered from their abdominal pain, while four still had symptoms. They felt frustrated by not having a diagnosis and by the lack of available treatment. Some who had been absent from school for weeks to months felt isolated and depressed. Focusing on positive thoughts and activities was reported to improve the pain. The abdominal pain could be considered a manifestation of mental problems.

CONCLUSIONS

Thinking differently about the symptoms reduced the FGIDs for the children and adolescents. The treating physicians as well as parents and teachers need to help the child focus on changing the mindset of pain.

Identifying threshold sizes for enlarged abdominal lymph nodes in different age ranges from about 200,000 individual's data

The threshold size for enlarged abdominal lymph nodes (E-ALNs), a common pediatric disorder, has yet to be standardized. According to the maximum short-axis diameter, this study divided ALNs into Grade A (≥ 10 mm), Grade B (8–10 mm), Grade C (5–8 mm), and Grade D (< 5 mm, normal). To identify the threshold size for E-ALNs, the prevalence of each grade was compared between asymptomatic individuals and symptomatic (e.g., abdominal pain) individuals without other diseases (e.g., appendicitis) that could explain the symptoms for different ages using data from > 200,000 individuals. The results showed the following: (1) For ages 1–3 years, the recommended threshold size is 8 mm, as the differences in the prevalence between the two groups were nonsignificant for Grade C but significant (p < 0.05) for both Grades A and B. (2) For ages 3–14 years, the recommended threshold size is 5 mm, as the differences between the two groups were significant (p < 0.05) for Grades A, B, and C. (3) The prevalence of Grades A, B, and C was very low for ages 0–1 years and high for ages 1–6 years. (4) The prevalence for males was generally higher than that for females for Grades A and B.

[Medical pain care for children and adolescents with chronic pain in Germany : An inventory]

Chronic pain in children and adolescents is increasing in prevalence, affects the quality of life, predisposes to pain in adulthood and causes numerous contacts to the healthcare system. In contrast, the number of therapeutic offers tailored to the special needs of this age group is insufficient and confusing. The working group on pain in children and adolescents of the German Pain Society therefore documented appropriate facilities in a questionnaire survey carried out using a snowball system. The response rate of 27/109 questionnaires was low. Thus, the results may not be entirely representative. Nevertheless, the heterogeneity of the offers and in total an undersupply became very clear. In order to improve the care situation, joint efforts by the various pediatric subdisciplines dealing with pain, an increase in the number of child pain treatment centers and a better networking are necessary.

Recurrent abdominal pain among adolescents: trends and social inequality 1991-2018

OBJECTIVES

The association between socioeconomic status and recurrent abdominal pain (RAP) among adolescents is an understudied issue. No study has examined whether such an association changes over time. The aim was to examine trends in RAP among adolescents in Denmark from 1991 to 2018, to examine whether there was social inequality in RAP and whether this inequality varied over time.

METHODS

The study used data from the Danish part of the international Health Behaviour in School-aged Children (HBSC) study of nationally representative samples of 11-, 13- and 15-year-olds. This study pooled data from eight comparable surveys from 1991 to 2018, overall participation rate 88.0%, n=30,048. The definition of RAP was self-reported stomach-ache daily or several days per week during the past six months. We reported absolute inequality as prevalence difference in RAP between low and high socioeconomic status and relative inequality as odds ratio for RAP by socioeconomic status.

RESULTS

In the entire study population, 5.6% reported RAP, 3.1% among boys and 7.8% among girls. There was a significant increase in RAP from 1991 to 2018 among boys and girls, test for trend, p<0.0001. The prevalence of RAP was significantly higher in low than high socioeconomic status, OR=1.63 (95% CI: 1.42-1.87). The absolute social inequality in RAP fluctuated with no consistent increasing or decreasing pattern.

CONCLUSIONS

The prevalence of RAP increased from 1991 to 2018. The prevalence was significantly higher among girls than among boys, and significantly higher in low socioeconomic status families. Professionals should be aware of RAP as common and potentially serious health problems among children and adolescents. In addition to clinical examination it is important to focus on improving the child's quality of life, reduce parents' and children's concerns about the seriousness of the condition, and consider supplements to medicine use.

Parental Opinion about the Low FODMAP Diet in Dietary Treatment of Children with Functional Abdominal Pain

The aim of this study was primarily to evaluate differences between parental opinion about the diet and overall changes in children’s symptoms of functional abdominal pain (FAP) during the low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet and National Institute for Health and Care Excellence (NICE) diet. Secondly, this paper examined the agreement between parental perception of children’s symptoms and children’s self-assessment of symptoms during the diet in both treatment groups. Twenty-seven children with diagnosed functional abdominal pain (FAP) were randomized to one of two group, receiving the low FODMAP diet or the diet based on NICE guidelines. Children reported gastrointestinal symptoms at baseline and during the diet. At the end of the intervention, parents assessed their children’s diet and symptoms changes, using Likert scales. The agreement between parental and children assessments of gastrointestinal symptoms was defined as the percentage of compatible answers. In the low FODMAP group a significantly lower percentage of parents (38%) declared that it was easy to follow the diet, compared to the NICE group (57%), (p = 0.017). A high percentage of parents in both groups reported improvement in all symptoms of children during dietary intervention. A high level of agreement was also observed between parental and children’s self-assessment of abdominal pain intensity and frequency. Our research suggests that in parental opinion the low FODMAP diet is as effective as the diet based on NICE guidelines in children with FAP. However, the low FODMAP diet may seem more difficult to follow, and this may have had an impact on the effectiveness and acceptability of the FODMAP diet by children.

Social Media Use in Adolescents With Functional Abdominal Pain

Social media use is increasing in children in the U.S., which could be related to the high prevalence of functional gastrointestinal disorders in this population. Objective: To investigate the relationship of social media use with the severity of gastrointestinal symptoms in patients with a functional abdominal pain or irritable bowel syndrome diagnosis. Study Design: We administered a questionnaire to collect information about screen time, demographics, and a modified Validated Varni PedsQL Gastrointestinal symptom scale which assesses the severity of gastrointestinal (GI) symptoms. Results: We surveyed a total of 59 subjects, which included 26 subjects with functional abdominal pain and 33 age-matched healthy controls. The median score across all 8 scales was about a third less for cases (median: 63; IQR: 55-78) than controls (median: 93; IQR: 83-95) (p < 0.001). Mean screen time in the study group (341 min/day) was very similar to that in the control group (331 min/day). There was no statistically significant association between screen time per day and the number of platforms used for either the cases or controls. YouTube (92%) and Instagram (88%) were the first and second most popular platforms used by the children with functional abdominal pain; Instagram (97%) and Snapchat (82%) were the most popular platforms in the healthy controls. Interestingly, social media were more often used for entertainment, reading, and productivity by the children with functional abdominal pain (p < 0.05). Conclusion: The amount of screen time/day and the number of social media platforms used does not correlate with the severity of abdominal pain and other GI symptoms in adolescents with FGID. Further research will be needed to confirm if the platforms are used differently by children with functional gastrointestinal disorder.
