Association between child maltreatment and constipation: a school-based survey using Rome III criteria

Navigating through 65 years of insights: lessons learned on functional abdominal pain in children

In 1958, Apley and Naish authored a groundbreaking paper in Archives of Disease in Childhood, elucidating the epidemiology and risk factors of recurrent abdominal pain in children-a subject that had confounded clinicians of their time. Surprisingly, even after 65 years, there are several unanswered questions regarding the etiology, pathophysiology, and management of pediatric abdominal pain. Contrary to the prevailing notion that children naturally outgrow functional abdominal pain, compelling evidence suggests it's possible these children develop a number of clinically significant psychological issues that could profoundly impact their quality of life and, consequently, future health and educational outcomes. In this light, we aimed to comprehensively review the current literature to update the knowledge of practicing clinicians on functional abdominal pain, summarizing the evidence from the last 65 years.Conclusion: The enduring unanswered questions surrounding childhood abdominal pain continue to challenge clinicians, resulting in unnecessary investigations, thereby contributing to substantial healthcare expenditures. It is also evident that children with long-standing symptoms would progress to adulthood with the potential to develop irritable bowel syndrome and many psychological disturbances. Several key interventions using pharmacological agents, such as amitriptyline, showed that some of these drugs are no more effective than the placebo in clinical trials. Several research during the recent past suggest that psychological interventions such as gut-directed hypnotherapy alleviate symptoms and ensure better prognosis in the long run. Therefore, clinicians and researchers must join hands to explore the pathophysiological mechanisms underpinning functional abdominal pain and novel therapeutic strategies to ensure the well-being of these children. What is Known: • Functional abdominal pain disorders are common among children, with a worldwide prevalence of 13.5% of children suffering from at least one of these disorders • These disorders contribute to a significant reduction in the quality of life of affected children and their families and lead to an array of psychological problems What is New: • The biological basis of functional abdominal pain is becoming more explicit, including complex interactions between altered microbiome, deranged motility, and psychological dysfunction with gut-brain interactions • Novel approaches giving minimal emphasis on pharmacological interventions and exploring psychological interventions are showing promising results.

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.

Childhood constipation: Current status, challenges, and future perspectives

Constipation in children is a major health issue around the world, with a global prevalence of 9.5%. They present to clinicians with a myriad of clinical signs. The Rome IV symptom-based criteria are used to diagnose functional constipation. Functional constipation is also a huge financial burden for healthcare system and has a detrimental impact on health-related quality of life of children. There are various risk factors identified globally, including centrally connected factors such as child abuse, emotional and behavioral issues, and psychological stress. Constipation is also precipitated by a low-fiber diet, physical inactivity, and an altered intestinal microbiome. The main pathophysiological mechanism is stool withholding, while altered rectal function, anal sphincter, pelvic floor, and colonic dysfunction also play important roles. Clinical evaluation is critical in making a diagnosis, and most investigations are only required in refractory patients. In the treatment of childhood constipation, both nonpharmacological (education and de-mystification, dietary changes, toilet training, behavioral interventions, biofeedback, and pelvic floor physiotherapy), and pharmacological (osmotic and stimulant laxatives and novel drugs like prucalopride and lubiprostone) interventions are used. For children with refractory constipation, transanal irrigation, botulinum toxin, neuromodulation, and surgical treatments are reserved. While frequent use of probiotics is still in the experimental stage, healthy dietary habits, living a healthy lifestyle and limiting exposure to stressful events, are all beneficial preventive measures.

Association between childhood constipation and exposure to stressful life events: a systematic review

BACKGROUND

Several cross-sectional studies have reported an association between childhood constipation and exposure to stressful events. We planned to systematically review the literature on constipation and its associated stressful events.

METHODS

PubMed, Embase, and PsycINFO databases were searched (until February 2021) using standard search terms related to "constipation" and "stress" from 0 to 18 years that describe the association between psychological stressors and constipation. Studies were screened using pre-designed eligibility criteria. Studies that fulfilled the criteria were reviewed in a full-text format. The quality assessment of selected articles was conducted using standard methods.

KEY RESULTS

Of 2296 titles and abstracts screened, 38 were included in the full-text review. Out of that, 15 articles were included in this systematic review. There were 2954 children with constipation, and the age range was from 6 months to 16 years. Exposure to home-related stressors (divorce or separation of parents, severe illness in family, and parental job loss) school-related stressors (including being bullied at school, change in school, separation from the best friend at school, and failure in an examination), exposure to child maltreatments and exposure to war/civil unrest were associated with childhood constipation.

CONCLUSIONS AND INFERENCES

Exposure to day-to-day home- and school-related stressors, to child maltreatment, and to civil unrest is associated with constipation in children and adolescents. These factors need to be explored during clinical evaluation of children with constipation.

Prevalence of suspected child abuse in children with constipation: a case-control study

BACKGROUND

A possible association between child abuse and neglect (CAN) and functional constipation (FC) has been described in adults, however, limited data are available in children. Our objective was to determine the prevalence of suspected CAN in children with FC as compared with their healthy peers.

METHODS

A case-control study was carried out in children aged 3-10 years. Children with FC were recruited at a tertiary outpatient clinic, and healthy controls were recruited at schools. Parents were asked to fill out questionnaires about the history and behaviour of their child, children were inquired using a semistructured interview about experienced traumatic events and sexual knowledge. The interview was scored by two independent observers. The prevalence of suspected CAN was determined according to the questionnaires and interview.

RESULTS

In total, 228 children with FC and 153 healthy controls were included. Both groups were age and gender comparable (50% females, median age 6 years (not significant)). No significant difference in the prevalence of suspected CAN was found between children with FC and healthy controls (23.3% vs 30.1%, 95% CI 0.44 to 1.12, p=0.14), including a suspicion of sexual, emotional and physical abuse.

CONCLUSION

Suspected CAN was detected in both children with FC as in healthy controls. The possible association between CAN and FC in children could not be confirmed.

Association between abuse and neglect with functional constipation and irritable bowel syndrome in adolescents

OBJECTIVES

To evaluate the association between violence exposure, abuse, and neglect victimization with functional constipation and irritable bowel syndrome in adolescents.

METHODS

Observational cross-sectional case-control study conducted with adolescents from two public schools in the municipality of Osasco, metropolitan region of São Paulo, Brazil. A self-administered questionnaire validated for Brazilian Portuguese Child Abuse Screening Tools - Children's version (ICAST-C) was used to screen the different types of violence. The definition of functional constipation and irritable bowel syndrome was performed using the Rome IV criteria for adolescents. Parents or legal guardians completed the questionnaire for socioeconomic assessment and signed the informed consent form.

RESULTS

265 students aged 11-17 years, 157 females, were evaluated. Functional constipation and irritable bowel syndrome were found in 74 (27.9%) of the 265 adolescents. Violence exposure was found in 82.6% of the 265 screened adolescents, physical abuse in 91.3%, psychological abuse in 93.2%, sexual abuse in 12.1%, and neglect in 53.6%. The multiple logistic regression analysis showed an association (p < .05) between functional constipation and irritable bowel syndrome with violence exposure (OR = 2.77), physical abuse (OR = 2.17), psychological abuse (OR = 2.95), and neglect (OR= 2.31). There was no association with sexual abuse.

CONCLUSIONS

Functional constipation and irritable bowel syndrome were associated with violence exposure, physical abuse, psychological abuse, and neglect in adolescent students from public schools. No association was found with sexual abuse. Further studies are necessary to investigate the causal relationship between violence and functional gastrointestinal disorders.

Impact of Parental Illness and Injury on Pediatric Disorders of Gut-Brain Interaction

OBJECTIVE

To evaluate the relationship between parental injury and illness and disorders of gut-brain interaction (DGBI) in children.

STUDY DESIGN

A self-controlled case series using data from the Military Health System Data Repository compared International Classification of Diseases, Ninth Revision-identified DGBI-related outpatient visits and prescriptions in 442 651 children aged 3-16 years in the 2 years before and the 2 years after the injury and/or illness of their military parent. Negative binomial regression was used to compare visit rates for constipation, fecal incontinence, abdominal pain, irritable bowel syndrome, and a composite of these before and after parental injury and/or illness. Logistic regression, clustered by child, compared the odds of stooling agent and antispasmodic prescription before and after parental injury and/or illness.

RESULTS

In the 2 years following parental injury and/or illness, children had increased visits for DGBIs (adjusted incidence rate ratio [aIRR] 1.09; 95% CI 1.07-1.10), constipation (aIRR 1.07; 95% CI 1.04-1.10), abdominal pain (aIRR 1.09; 95% CI 1.07-1.12), and irritable bowel syndrome (aIRR 1.37; 95% CI 1.19-1.58). Following parental injury and/or illness, the odds of stooling agent prescription decreased (aOR 0.95; 95% CI 0.93-0.97) and the odds of antispasmodic prescription increased (aOR 1.26; 95% CI 1.18-1.36).

CONCLUSIONS

Parental injury and/or illness is associated with increased healthcare use for DGBIs. Parental health should be considered by clinicians when assessing DGBIs, counseling patients, and formulating treatment plans.

Prevalence of functional gastrointestinal disorders in infants and young children in China

BACKGROUND

The prevalence of functional gastrointestinal disorders (FGIDs) in children, particularly from Asia, is largely unknown. There are not many studies done in Asia especially using the Rome IV criteria. The aim of this study is to assess the prevalence of FGIDs in infants and young children in a representative sample in China.

METHODS

A prospective, cross-sectional, community-based survey was conducted among healthy infants and young children between the ages of 0-4 years in Jinhua and Shanghai, China. A total of 2604 subjects (1300 subjects from Jinhua and 1304 subjects from Shanghai) completed a validated questionnaire on pediatric gastrointestinal symptoms. FGIDs in infants and young children were diagnosed using the Rome IV criteria.

RESULTS

According to the Rome IV criteria, the prevalence of having a FGID in Chinese infants and young children is 27.3%. Infant regurgitation (33.9%) was the most common FGID among the 0-6 months old while functional constipation (7.0%) was the most common among the 1-4 years old. Risk factor analysis revealed that prevalence of infantile colic was higher with better maternal education and low birth weight. Prevalence of infantile regurgitation was significantly greater in males, living in a rural area, being exclusively breast fed at least up to 4 months and starting formula feeds within the first month. The risk of functional constipation was lower for infants who were delivered vaginally.

CONCLUSIONS

Infantile regurgitation was the most common FGID in Chinese infants while functional constipation was most prevalent among young Chinese children.

Association Between Hyperactivity Symptoms and Somatic Complaints: Mediating and Moderating Mechanisms in Childhood Trauma and Life Events Among Chinese Male Adolescents

Background: Prior research has found that attention deficit/hyperactivity disorder (ADHD) - particularly hyperactivity symptoms - is associated with various somatic complaints. The present study further tests the relationship between hyperactivity symptoms and somatic complaints in Chinese male adolescents and explores the underlying moderating and mediating mechanisms. Methods: Our sample included 1,586 males (age = 12-16) recruited as part of an epidemiological study of child and adolescent mental disorders from April to July, 2014. Hyperactivity symptoms and somatic complaints were assessed with Achenbach's Child Behavior Checklist (CBCL), and the Childhood Trauma Questionnaire Short Form (CTQ-SF) and Adolescent Life Events Scale (ASLEC) were used to assess exposure to childhood trauma and recent life events. Results: Adolescents with hyperactivity symptoms experienced more emotional abuse, physical abuse, life events, and reported more somatic complaints symptoms (p < 0.0083 or p < 0.05). Linear regression analysis showed that hyperactivity, total childhood trauma score/emotional abuse and sexual abuse and ASLEC score significantly predicted somatic complaints (all p < 0.05). Emotional abuse and life events mediated the relationship between hyperactivity symptoms and somatic complaints. Furthermore, childhood trauma moderated the path between hyperactivity symptoms and ASLEC in the moderation mediation model for predicting somatic complaints (p < 0.05). Conclusions: Hyperactivity symptoms had a significant impact on somatic complaints among Chinese male adolescents. Furthermore, childhood trauma and life events affected the relationship between hyperactivity symptoms and somatic complaints. Interventions for somatic complaints in male adolescents with hyperactivity symptoms should thus consider history of childhood trauma and life events.

Behavioral and emotional problems in adolescents with constipation and their association with quality of life

Objectives

To assess behavioral and emotional problems in children and adolescents with functional constipation and their relationship with psychological maladjustment and health-related quality of life (HRQoL).

Design

A school-based cross-sectional survey conducted in 8 randomly selected schools from 4 randomly selected districts in Sri Lanka. A previously validated questionnaire was used for data collection. Behavioral and emotional problems were assessed using the Sinhala version of the Child Behavior Check List (CBCL-S/4-18). Constipation was diagnosed by applying the Rome III criteria.

Results

A total of 1000 questionnaires were distributed, and 913 completed questionnaires were included in the analysis. Sixty adolescents (6.5%) had functional constipation. Scores obtained for isolated psychological problems such as withdrawal (3.1 [3.1] vs. 1.9 [2.4], p<0.001), somatic complaints (3.2 [2.8] vs. 2.3 [2.5], p<0.05) anxiety/depression (5.8 [2.5] vs. 3.9 [3.6], p<0.001), social problems (3.0 [2.7] vs. 2.2 [1.9] p<0.001) and attention problems (5.4 [4.1] vs. 3.9 [3.4], p<0.001), and broadband scale of internalization (12.1 [8.4] vs. 8.3 [7.2], p<0.05) and mean total CBCL-S/4-18 score (29.4 [19.5] vs. 23.2 [17.0], p<0.001) were higher in adolescents with functional constipation. Clinical characteristics, socio-demographic and family factors and psychological maladjustment had no relationship with externalization, internalization and total CBCL-S/4-18 score. Internalization (-0.49, p<0.0001), externalization (-0.30, p<0.05), and total CBCL-S/4-18 (-0.44, p<0.001) scores had a negative impact on HRQoL of adolescents with functional constipation.

Conclusions

Adolescents with functional constipation are suffering from significant behavioral and emotional problems. These problems negatively affect their HRQoL.

Clinical Evaluation of a Patient With Symptoms of Colonic or Anorectal Motility Disorders

Constipation, irritable bowel syndrome, fecal incontinence, abdominal pain, and anorectal pain are problems that affect 40% of the population. They commonly present with overlapping symptoms indicating that their pathophysiology affects multiple segments of the gut as well as brain and gut interactions. Clinically, although some conditions are readily recognized, dyssynergic defecation, fecal incontinence, and anorectal pain are often missed or misdiagnosed. Consequently, the assessment of lower gastrointestinal symptoms in patients with suspected colonic or anorectal motility disorder(s) remains challenging for most clinicians. A detailed history, use of the Bristol stool form scale, prospective stool diaries, ideally through a phone App, digital rectal examination, and judicious use of complementary diagnostic tests are essential. Additionally, it is important to evaluate the impact of these problems on quality of life and psychosocial issues, because they are intricately linked with these disorders. The Rome IV diagnostic questionnaire for functional gastrointestinal disorders can provide additional information often missed during history taking. Here, we discuss a systematic approach for the clinical evaluation of patients with suspected lower gastrointestinal problems, grouped under 4 common diagnostic categories. We describe how to take a detailed history, perform meticulous digital rectal examination, and use validated tools to supplement clinical evaluation, including assessments of quality of life and scoring systems for disease severity and digital Apps. These tools could facilitate a comprehensive plan for clinical management including diagnostic tests, and translate the patients' complaints into definable, diagnostic categories.

Mind and gut: Associations between mood and gastrointestinal distress in children exposed to adversity

Gastrointestinal and mental disorders are highly comorbid, and animal models have shown that both can be caused by early adversity (e.g., parental deprivation). Interactions between the brain and bacteria that live within the gastrointestinal system (the microbiome) underlie adversity-gastrointestinal-anxiety interactions, but these links have not been investigated during human development. In this study, we utilized data from a population of 344 youth (3-18 years old) who were raised with their biological parents or were exposed to early adverse caregiving experiences (i.e., institutional or foster care followed by international adoption) to explore adversity-gastrointestinal-anxiety associations. In Study 1, we demonstrated that previous adverse care experiences were associated with increased incidence of gastrointestinal symptoms in youth. Gastrointestinal symptoms were also associated with concurrent and future anxiety (measured across 5 years), and those gastrointestinal symptoms mediated the adversity-anxiety association at Time 1. In a subsample of children who provided both stool samples and functional magnetic resonance imaging of the brain (Study 2, which was a "proof-of-principle"), adversity was associated with changes in diversity (both alpha and beta) of microbial communities, and bacteria levels (adversity-associated and adversity-independent) were correlated with prefrontal cortex activation to emotional faces. Implications of these data for supporting youth mental health are discussed.

Functional constipation in infancy and early childhood: epidemiology, risk factors, and healthcare consultation

Background

Functional constipation (FC) is a pediatric problem that is seen frequently. However, its prevalence in Asia remains undetermined. In this study we attempted to determine the prevalence, risk factors and therapeutic modalities of FC in infants and toddlers in Sri Lanka.

Methods

Children aged 6.5 months to 4 years were selected from 14 well-baby and vaccination clinics in the Gampaha District of Sri Lanka. A questionnaire with questions regarding the socio-demographic characteristics, child’s bowel habits, psycho-social risk factors and treatment modalities were filled by the mothers. FC was diagnosed according to ROME III criteria.

Results

A total of 1113 children were analyzed [(female n = 560 (50.3%) with a mean age of 20.7 months, standard deviation [SD] 11.2 months. FC was found in 89 (8.0%). FC was significantly and independently associated with underweight (14.3% vs 7.2%, p = 0.008. [OR and 95% CI: 2,3 (CI; 1.3–4.2)] and residence in an urban area (9.6% vs 5.6%, p = 0.013). [OR and 95% CI: 0.592 (CI; 0.396–0.95)]. Children subjected to violence showed a significantly higher prevalence of FC (20.0 vs 7.8%, p = 0.046). Children being overweight and children living with mothers subjected to violence showed a higher, though not statistically significant, tendency to develop FC. Children with FC visited healthcare clinics more frequently when compared to controls (19.6% vs 6.0%, p < 0.0001). However, only 24% of infants and toddlers with FC were treated specifically for the condition by a doctor.

Conclusions

FC occurred in 8% of this cohort of Sri Lankan infants and toddlers. It is significantly associated with underweight and living in an urban area. Only a quarter of them received medical attention for their constipation.

A Novel Screening Tool for Assessing Child Abuse: The Medical Somatic Dissociation Questionnaire-MSDQ

Somatic dissociation is known to be associated with childhood abuse, particularly with childhood sexual abuse (CSA). Currently, the diagnosis of CSA is hampered by the lack of a validated questionnaire. While some questionnaires are excellent research tools, there is no suitable applied measure for the assessment of distress due to CSA. The current study's objective was to validate a novel questionnaire, designated the Medical Somatic Dissociation Questionnaire-MSDQ, for evaluating somatic dissociation in the healthcare system setting. A total of 541 adults, 160 (30%) male and 381 (70%) female, of average age 35 years were recruited from the general population via the Internet. The Life Events Checklist for DSM-5 (LEC-5) was used for screening subjects for reporting a history of CSA. Our examination of the MSDQ indicated powerful internal consistency, reliability, and convergent validity of the instrument, with high correlations between the MSDQ and the SDQ-20 and also between the MSDQ and psychological symptomatology. In addition, there was known-groups validity when differences between adults who experienced CSA and those who did not were compared. Importantly, the MSDQ can be easily integrated into the evaluation process performed by medical professionals in the diagnosis of adult patients with apparently unexplained symptomatology.

Epidemiology of Paediatric constipation in Indonesia and its association with exposure to stressful life events

Background

We aimed to study the epidemiology and risk factors, including exposure to emotional stress, for constipation in Indonesian children and adolescents of 10–17 year age group.

Methods

A cross-sectional survey using a validated, self-administered questionnaire was conducted in randomly selected children and adolescents in nine state junior high schools from five districts of Jakarta. All of them were from urban areas. Constipation was defined as a diagnosis by using the Rome III criteria.

Results

Of 1796 children included in the analysis, 328 (18.3%; 95% CI 016–0.2) had constipation. Females and those residing in North Jakarta showed risks associated with constipation in school-age children and adolescents. Symptoms independently associated with constipation were abdominal pain (64% vs 43.3% of control) and straining (22.9% vs 6.3%). The prevalence of constipation was significantly higher in those with stressful life events such as father’s alcoholism (adjusted OR 1.91, 95% CI 1.27–2.89, P = 0.002), severe illness of a close family member (adjusted OR 1.77, 95% CI 1.12–2.80, P = 0.014), hospitalization of the child for another illness (adjusted OR 1.68, 95% CI 1.22–2.31, P < 0.001), being bullied at school (adjusted OR 1.67, 95% CI 1.01–2.76, P = 0.047) and loss of a parent’s job (adjusted OR 1.39, 95% CI 1.03–1.88, P = 0.034).

Conclusions

Constipation in children and adolescent is a significant health problem, affecting almost 20% of Indonesian school-age children and adolescents. Common school and home related stressful life events appear to have predisposed these children to develop constipation.

A Link between Nutritional and Growth States in Pediatric Patients with Functional Gastrointestinal Disorders

OBJECTIVE

To investigate nutritional status and growth status of pediatric patients with functional gastrointestinal disorders (FGIDs) and to examine the relationship between nutritional status and linear growth in these children.

STUDY DESIGN

In total, 102 pediatric patients diagnosed with functional constipation (FC), irritable bowel syndrome (IBS), or functional abdominal pain (FAP) in years 2013-2015 were subjected to anthropometric measurements. Anthropometry comprised body height, leg and trunk lengths, body weight, mid-upper arm circumference, and 3 skinfold thicknesses. Body fat percentage was obtained with bioelectrical impedance analysis. Indices of the nutritional status and body proportions were calculated and adjusted for age and sex.

RESULTS

Excessive body weight and excessive fatness were the most common in children with IBS. Being underweight was most common in children with FAP, but fat deficiency was similarly frequent in the FAP and in FC groups. Short stature was the most common in children with FC. Children with IBS were the best nourished and the tallest for age and sex due to increased trunk length. Body height and linear body proportions adjusted for age and sex were positively associated with body weight and body fatness in the total sample.

CONCLUSIONS

Children with FGIDs present various linear growth abnormalities that are associated with body weight and body fatness. Although excessive body weight and body fat are common in children with IBS, pediatricians should be aware of the risk of malnutrition in children with other FGIDs.

Aerophagia in adolescents is associated with exposure to adverse life events and psychological maladjustment

BACKGROUND

Aerophagia is a common childhood functional gastrointestinal disorder. We studied the association between adverse life events (ALEs), psychological maladjustment, somatization, and aerophagia (AP) in adolescents. We also assessed the impact of AP on their health-related quality of life (HRQoL).

METHODS

A cross-sectional survey was conducted on 2500 subjects of 13-18 years in 8 randomly selected schools in Sri Lanka. Translated, validated, and self-administered questionnaires were used to collect data. Aerophagia was diagnosed using Rome III criteria.

KEY RESULTS

A total of 2453 questionnaires were analyzed (males 1200 [48.9%], mean age 14.8 years, SD 1.6 years). Of them, 371 adolescents had AP (15.1%). Aerophagia was associated with exposure to physical abuse (20.4% vs. 12.7% in controls, P < .0001), emotional abuse (20.3% vs. 8.2% in controls, P < .0001), and other ALEs (22% vs. 10.2% in controls, P < .001). One hundred and ninety (51.2%) adolescents with AP and 775 (37.2%) controls had a personality score above the international cutoff value of 105, indicating psychological maladjustment (odds ratio 1.77, 95% confidence interval 1.42-2.21, P < .0001). Those with AP had higher somatization (16.4 vs. 8.9) and lower overall HRQoL scores (77.0 vs. 85.1, P < .0001). HRQoL scores of adolescents with AP were lower in all domains, namely, physical (80.6 vs. 86.9), emotional (69.1 vs. 80.3), social (83.8 vs. 90.5), and school (72.6 vs. 82.5) functioning (P < .0001).

CONCLUSIONS AND INFERENCES

Aerophagia was associated with exposure to ALEs and psychological maladjustment. Affected teenagers suffer from more somatic symptoms and has a poor HRQoL.

Youth self-report of child maltreatment in representative surveys: a systematic review

INTRODUCTION

This systematic review identified population-representative youth surveys containing questions on self-reported child maltreatment. Data quality and ethical issues pertinent to maltreatment data collection were also examined.

METHODS

A search was conducted of relevant online databases for articles published from January 2000 through March 2016 reporting on population-representative data measuring child maltreatment. Inclusion criteria were established a priori; two reviewers independently assessed articles to ensure that the criteria were met and to verify the accuracy of extracted information.

RESULTS

A total of 73 articles reporting on 71 surveys met the inclusion criteria. A variety of strategies to ensure accurate information and to mitigate survey participants' distress were reported.

CONCLUSION

The extent to which efforts have been undertaken to measure the prevalence of child maltreatment reflects its perceived importance across the world. Data on child maltreatment can be effectively collected from youth, although our knowledge of best practices related to ethics and data quality is incomplete.

Clinical practice: recognizing child sexual abuse-what makes it so difficult?

Recognizing child sexual abuse (CSA) in children is difficult, as there can be many hurdles in the assessment of alleged CSA. With this paper, we try to improve the recognition of CSA by discussing: (1) the difficulties regarding this matter and (2) the diagnostic evaluation of alleged CSA, combining both practical clinical recommendations based on recent research. Children are restrained to disclose CSA due to various reasons, such as fears, shame, and linguistic or verbal limitations. Associations between CSA and urogenital or gastrointestinal symptoms, internalizing and externalizing behavioral problems, post-traumatic stress symptoms, and atypical sexual behavior in children have been reported. However, these symptoms are non-specific for CSA. The majority of sexually abused children do not display signs of penetrative trauma at anogenital examination. Diagnosing a STI in a child can indicate CSA. However, other transmission routes (e.g., vertical transmission, auto-inoculation) need to be considered as well.Conclusion: The assessment consists of medical interview and child interview (parents and child separate and together) with special attention to the child's development and behavior (problems), psychosocial situation and physical complaints, the child's mental health, and the child's trauma history; anogenital examination should be done in all cases of alleged CSA. The examination should be documented by photo or video graphically. Recent research suggests that videography may be the preferred method, and testing on STIs. The assessment should be done multidisciplinary by experienced professionals. Health-care professionals who care for children need to know how child protective agencies and law enforcement are organized. In case there are concerns about a child's safety, the appropriate authorities should be alarmed. What is Known: • Sexual abuse in children often remains unrecognized in the majority of cases. What is New: • Research suggests that videographic documentation is preferred above photographic documentation for anogenital examination; observations of children's behavioral reactions during examinations might be valuable in the evaluation of suspected sexual abuse; nucleic acid amplification testing can be used on vaginal swabs or urine samples for chlamydia and gonorrhea; the CRIES-13 and the CAPS-CA can be used to assess trauma-symptoms in children after sexual abuse.

Constipation and Constipation-predominant Irritable Bowel Syndrome: A Comparative Study Using Rome III Criteria

OBJECTIVE

The aim of the present study is to compare functional constipation (FC) and constipation-predominant irritable bowel syndrome (IBS-C) in adolescents.

METHODS

A school-based survey was conducted involving adolescents ages 13 to 18 years. A set of validated questionnaires including Rome III questionnaire for functional gastrointestinal disorders in children/adolescents, somatization inventory, quality of life inventory, and childhood traumatic events inventory were used for data collection. FC and IBS-C were defined using Rome III criteria.

RESULTS

A total of 1792 adolescents (975 boys [45.4%]) were included in the analysis. Prevalence of FC and IBS-C were 7.7% and 1.6%, respectively. Bowel habits such as stool frequency <3 per week (10% vs 44.9%, P < 0.0001), hard stools (20% vs 40.5%, P < 0.05), painful defecation (33.3% vs 56.5%, P < 0.05), large diameter stools (23.3% vs 50.7%, P < 0.01), stool withholding behavior (20% vs 44.2%, P < 0.05), were more commonly associated with FC than did IBS-C. Occurrence of fecal incontinence (0% vs 8%, P = 0.21), urgency (56.7% vs 66.7%, P = 0.65), and straining (56.7% vs 36.9%, P = 0.47) was not significantly different between IBS-C and FC. Exposure to physical abuse, emotional abuse, and sexual abuse was equally prevalent among adolescents with FC and IBS-C. There was no difference between somatization scores, and health-related quality of life between the 2 groups.

CONCLUSIONS

Although bowel habits related to stool withholding are more prevalent in FC, than in IBS-C, they are more likely to be a spectrum of a disorder rather than 2 separate entities.

[Domestic violence and constipation: an integrative review]

OBJECTIVE

To search the literature for evidence of a relationship between domestic violence and constipation.

METHODS

An integrative review was conducted using the six-step approach and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We examined articles published between 2005 and 2015 investigating the correlation between domestic violence and constipation. The search was performed in September and October of 2015 in PubMed, MEDLINE, Scopus, and Web of Science. The selection of articles was performed in three stages: search, pre-selection, and inclusion.

RESULTS

Of 177 articles identified, 11 were included in the review. Of these 11 articles, seven were quantitative, three were qualitative, and one was mixed. Four articles focused on children and adolescents, two investigated medical knowledge regarding the relationship between domestic violence and constipation, one reviewed digestive disorders in the elderly, one evaluated the results of biofeedback for the treatment of constipated individuals with or without a history of violence, and one evaluated evacuatory disorders and correlated the result of defecography with history of domestic violence. Finally, two studies were specialist reports. Level of evidence was 1B and recommendation grade A in three studies. All studies detected a relationship between domestic violence and intestinal constipation.

CONCLUSION

The results of the present review support a correlation between domestic violence and intestinal constipation. The investigation of this relationship is recommended in clinical practice.

Psychological maladjustment and quality of life in adolescents with constipation

OBJECTIVES

To assess psychological maladjustment in adolescents with functional constipation.

STUDY DESIGN

We conducted a cross-sectional survey in five schools. Adolescents aged between 13 and 18 years were included in the study. Validated questionnaires were used to collect bowel habits and demographic data, health-related quality of life (HRQoL) and psychological maladjustment. Rome III criteria were used to diagnose constipation.

RESULTS

1697 adolescents were recruited (boys 779 (45.9%), mean age 15.06 years and SD 1.6 years). Prevalence of constipation was 6.7%, of whom 52 were boys (45.6%) and 62 were girls (54.4%). 38 adolescents (33.3%) with constipation and 230 controls (14.5%) had significant psychological maladjustment. Among seven different personality dimensions used to assess psychological maladjustment, children with constipation had significantly more deficits than controls in hostility and aggression (14.2 vs 12.6 in controls (mean difference 1.54, 95% CI (0.89 to 2.19) p<0.001), negative self-esteem (12.0 vs 10.5 in controls, mean difference 1.54 95% CI (0.96 to 2.06) p<0.001), negative self-adequacy (11.9 vs 9.8 controls, mean difference 2.07 95% CI (1.46 to 2.67) p<0.001), emotional unresponsiveness (12.9 vs 11.5 controls, mean difference 1.44 95% CI (0.84 to 2.04) p<0.001), emotional instability (17.1 vs 15.6, mean difference 1.53 95% CI (0.86 to 2.2) p<0.001) and negative world view (12.1 vs 10.2 controls, mean difference 1.91 95% CI (1.24 to 2.59) p<0.001). The total HRQoL of adolescents with constipation was lower than controls (70.6 vs 79.0 mean difference 9.48 95% CI (1.4 to 6.7) p<0.05).

CONCLUSION

A significant proportion of children with constipation are suffering from psychological maladjustment.

Physical symptoms in very young children assessed for sexual abuse: a mixed method analysis from the ASAC study

So far, a recognizable pattern of clinical symptoms for child sexual abuse (CSA), especially in young male children, is lacking. To improve early recognition of CSA, we reviewed physical complaints, physical examination, and tests on sexually transmitted infections (STIs) in confirmed victims (predominantly preschool boys) of CSA from the Amsterdam sexual abuse case (ASAC). We retrospectively analyzed the outcomes of the primary assessment using mixed methods: descriptive analysis of physical complaints, physical exams, and STI tests from medical files and a qualitative analysis on expert's interpretations of physical complaints and children's behavior during physical examination. We included 54 confirmed CSA victims, median age 3.2 (0-6) years, 43 boys (80%), and 11 girls (20%). Physical complaints were reported in 50%, of which gastrointestinal and anogenital complaints were most common. None of the children showed CSA-specific genital signs at physical examination. Most prominent finding during physical examination was a deviant behavioral response (anxiety, withdrawal, too outgoing) in 15 children (28%), especially in children who experienced anal/vaginal penetration. Testing for STIs was negative.

CONCLUSION

Physical complaints and physical signs at examinations were non-specific for CSA. Deviant behavioral reactions during physical examination were the most prominent finding. Precise observation of a child's behavior during physical examination is needed. What is known • Child sexual abuse (CSA) affects many children on both the short and the long term but remains unrecognized in most cases. • So far, there is a lack of studies on symptom patterns of CSA in male, preschool children. What is new • None of the children showed CSA-specific findings at physical and anogenital examination; STIs were not found in the confirmed victims of CSA. • The most prominent finding was the deviant behavioral response of the children examined, especially in children who experienced anal/vaginal penetration; therefore, precise observation of a child's behavior during physical examination is a crucial part of the evaluation of suspected CSA.

Serum motilin levels and motilin gene polymorphisms in children with functional constipation

BACKGROUND

Functional constipation is an important clinical problem among chidren all over the world. Its main cause is not completely understood. Motilin is a gastrointestinal hormone that increases intestinal motility. In this study, we aimed to investigate the serum motilin levels and its relationship with stool consistency and motilin gene polymorphisms in constipated children.

METHODS

In this study we investigated 91 constipated patients (mean age 6.84±3.55 years) and 100 healthy controls (mean age 7.78±4.25 years). Serum motilin levels were assessed by sandwich enzyme-linked immunosorbent assay. rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) mutations were evaluated for motilin gene polymorphisms.

RESULTS

Serum motilin levels were significantly lower in constipated children than healthy controls (6.20±7.86 vs. 11.54±17.89 pg/mL, respectively, P=0.008). Serum motilin levels were significantly correlated with Bristol stool scale rate (r=0.193, P=0.011) in whole study group, but in the constipation group there was no significant correlation (r=-0.072, P=0.528). There were no differences in terms of presence or distribution of the polymorphisms of rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) in both groups. There was not a significant difference between different polymorphism groups regarding serum motilin concentrations in whole study group and also in both of the study groups.

CONCLUSIONS

This study indicated for the first time that serum motilin levels decreased in constipated children. Further studies are needed to clarify whether motilin or motilin gene polymorphisms has a role in pathogenesis of functional constipation.

Childhood constipation as an emerging public health problem

Functional constipation (FC) is a significant health problem in children and contrary to common belief, has serious ramifications on the lives of children and their families. It is defined by the Rome criteria which encourage the use of multiple clinical features for diagnosis. FC in children has a high prevalence (0.7%-29%) worldwide, both in developed and developing countries. Biopsychosocial risk factors such as psychological stress, poor dietary habits, obesity and child maltreatment are commonly identified predisposing factors for FC. FC poses a significant healthcare burden on the already overstretched health budgets of many countries in terms of out-patient care, in-patient care, expenditure for investigations and prescriptions. Complications are common and range from minor psychological disturbances, to lower health-related quality of life. FC in children also has a significant impact on families. Many paediatric clinical trials have poor methodological quality, and drugs proved to be useful in adults, are not effective in relieving symptoms in children. A significant proportion of inadequately treated children have similar symptoms as adults. These factors show that constipation is an increasing public health problem across the world with a significant medical, social and economic impact. This article highlights the potential public health impact of FC and the possibility of overcoming this problem by concentrating on modifiable risk factors rather than expending resources on high cost investigations and therapeutic modalities.

Abdominal Pain-predominant Functional Gastrointestinal Disorders in Adolescent Nigerians

OBJECTIVES

To determine the prevalence, pattern, and predisposing factors of abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs) in adolescent Nigerians.

METHODS

A cross-sectional study was conducted in 2 states in the southern part of Nigeria in June 2014. Adolescents of age 10 to 18 years were recruited from 11 secondary schools using a stratified random sampling technique. A validated self-administered questionnaire on Rome III criteria for diagnosing AP-FGIDs and its determinants were filled by the participants in a classroom setting.

RESULTS

A total of 874 participants filled the questionnaire. Of this, 818 (93.4%) filled it properly and were included in the final analysis. The mean age of the participants was 14.6 ± 2.0 years with 409 (50.0%) being boys. AP-FGIDs were present in 81 (9.9%) participants. Forty six (5.6%) of the study participants had irritable bowel syndrome (IBS), 21 (2.6%) functional abdominal pain, 15 (1.8%) abdominal migraine while 3 (0.4%) had functional dyspepsia. The difference in AP-FGIDs between adolescents residing in rural and urban areas was not statistically significant (P = 0.22). Intestinal and extra-intestinal symptoms occurred more frequently in those with AP-FGIDs. Nausea was the only symptom independently associated with AP-FGIDs (p = 0.015). Multiple regression analysis showed no significant association between stressful life events and AP-FGIDs.

CONCLUSIONS

AP-FGIDs are a significant health problem in Nigerian adolescents. In addition to the intestinal symptoms, most of the affected children and others also had extraintestinal symptoms. None of the stressful life events evaluated was significantly associated with FGIDs.

Results of the implementation of a new screening protocol for child maltreatment at the Emergency Department of the Academic Medical Center in Amsterdam

OBJECTIVE

This study examines the results of the implementation of a new screening protocol for child maltreatment (CM) at the Emergency Department (ED) of the Academic Medical Center in Amsterdam, The Netherlands. This protocol consists of adding a so called 'top-toe' inspection (TTI), an inspection of the fully undressed child, to the screening checklist for child maltreatment, the SPUTOVAMO.

DESIGN

We collected data from all patients 0-18 years old directly after introduction (February 2010) and 9 months later. Outcome measures were: completion of the screening and reasons for non-adherence. Data were collected on age, gender, reason for visiting the ED (defined by International Classification of Disease, ICD), presence of a chronic illness, type of professional performing the TTI and admission during week or weekend days.

RESULTS

In February 560 and in November 529 paediatric patients were admitted. In February the complete screening protocol was performed in 42% of all children, in November in 17%. A correlation between completion of the SPUTOVAMO and having a TTI performed was found. Older age and presence of a chronic illness influenced the chance of having both SPUTOVAMO and TTI performed negatively. The completion rate of SPUTOVAMO was influenced by ICD code. Completion of TTI was influenced by type of investigator. The best performing professional was the ED physician followed by the paediatrician followed by the ED nurse. The reasons for not performing a TTI were not documented. Refusal of the TTI by a patient or parent was reported three times.

CONCLUSION

Implementation of this new screening protocol for CM was only mildly successful and declined in time. A negative correlation between older child age and having a chronic illness and completion of the screening was found. A practical recommendation resulting from this study could be that, if CM screening protocols prove to be effective in detecting CM, regular training sessions have to be held. Filling out the checklist is something that could be performed by ED nurses. Performing a TTI is perhaps easier for the ED physicians to make part of their daily routine.
