Prevalence and persistence of stomach ache and headache among children. Follow-up of a cohort of Norwegian children from 4 to 10 years of age

I. INTRODUCTION: UNDERSTANDING THE TRANSITION TO SIBLINGHOOD FROM A DEVELOPMENTAL PSYCHOPATHOLOGY AND ECOLOGICAL SYSTEMS PERSPECTIVE

The birth of an infant sibling is a common occurrence in the lives of many toddler and preschool children. Early childhood is also a time for the emergence of disruptive behavior problems that may set the stage for later problem behaviors. The current study examined individual differences in young children’s behavioral and emotional adjustment after the birth of a sibling in an effort to uncover developmental trajectories reflecting sudden and persistent change (maladaptation), adjustment and adaptation (resilience), gradual linear increases, and no change (stability and continuity). Growth mixture modeling (GMM) was conducted with a sample of 241 families expecting their second child using a longitudinal research design across the first year after the sibling’s birth (prenatal, 1, 4 8 and 12 months) on seven syndrome scales of the Child Behavior Checklist (CBCL 1.5–5:(Achenbach & Rescorla, 2000 ): aggression, attention problems, anxiety/depression, emotional reactivity, withdrawal, somatic complaints, and sleep problems. For all scales, multiple classes describing different trajectory patterns emerged that reflected predominantly intercept differences; children high on problem behavior after the birth were those high before the birth. There was no evidence of a sudden, persistent maladaptive response indicating children underwent a developmental crisis for any of the problem behaviors examined. Most children were low on all problem behaviors examined and showed little change or actually declined in problem behaviors over time, although some children did experience more pronounced changes in the borderline clinical or clinical range. Only in the case of aggressive behavior was there evidence of an Adjustment and Adaptation Response showing a sudden change (prenatal to 1 month) that subsided by 4 months, suggesting that some young children react to stressful life events but adapt quickly to these changing circumstances. Further, children’s withdrawal revealed a curvilinear, quadratic path, suggesting children both increased and decreased in their withdrawal over time. Guided by a developmental ecological systems framework, we employed data mining procedures to uncover the child, parent, and family variables that best discriminated the different trajectory classes and found that children’s temperament, coparenting, parental self-efficacy, and parent-child attachment relationships were prominent in predicting children’s adjustment after the birth of an infant sibling. Finally, when trajectory classes were used to predict sibling relationship quality at 12 months, children high on aggression, attention problems, and emotional reactivity in the year after the birth engaged in more conflict and less positive involvement with the infant sibling at the end of the first year.

Parental health and psychosomatic symptoms in preschool children: A cross-sectional study in Scania, Sweden

Aim: The aim of the study was to assess the association between parental self-rated health and recurrent abdominal pain (RAP) in preschool children. Methods: A questionnaire, including questions about sociodemographic and psychosocial factors, lifestyle, parental and child health, was sent to parents of all 4-year-old children in Scania, Sweden. The response rate was 43.6%. The outcome was RAP and the main exposure was parental self-rated health (SRH). Covariates included sociodemographic, lifestyle and psychosocial factors. Logistic regression analyses were used in a five-step model to estimate the odds ratio (OR) and 95% confidence interval (CI) of parental SRH in relation to child RAP. Results: Logistic regression analysis showed higher odds of RAP among children whose parents reported domestic violence, economic worries and poor SRH (mothers OR = 2.1 (95% CI: 1.6, 2.7) and fathers OR = 1.5 (95% CI: 1.1, 2.0)). Adjustment for sociodemographic, lifestyle and psychosocial factors reduced the OR for RAP in the children of mothers with poor SRH (OR = 1.6 (95% CI: 1.2, 2.2)) and fathers with poor SRH (OR = 1.2 (CI 95%: 0.8, 1.7)). Poor SRH was associated with less reading to the child as well as parental perceptions of insufficiency in the interaction with the child. Conclusions: Health professionals have a key position to prevent psychosomatic symptoms in childhood by identifying the living conditions of children with RAP and particularly, to pay attention to parental poor health to identify if support to the family and/or child protection interventions are needed. Health professionals meeting adult patients with poor health should identify whether they are parents and have children who might need information, support and/or protection.

Systematic review of childhood and adolescent risk and prognostic factors for persistent abdominal pain

This review aimed to identify childhood and adolescence risk and prognostic factors associated with onset and persistence of persistent abdominal pain and related disability and assess quality of the evidence. While findings suggest a possible role for negative emotional symptoms and parental mental health as risk and prognostic factors for onset and persistence of persistent abdominal pain, the evidence is of poor quality overall and nonexistent when it comes to prognostic factors associated with disability.

CONCLUSION

Further research is needed to increase confidence in existing evidence and to explore new factors. This research will inform prevention.

Migraine in childhood: biobehavioural or psychosomatic disorder?

It is well documented that headache is a multifactorial disorder which includes not only genetic, biological, medical and neuropsychological factor but also psychological and personality traits. The close relationship between stress and migraine attacks and the significant psychiatric comorbidities in migraine provide evidence of a “paradigm” of tight interaction between somatic and psychological aspects in paediatric migraine. In particular in younger children, an uncomfortable situation, a psychological problem or an emotional distress is rarely expressed directly but usually through physical symptoms. So migraine may be considered as a disorder of psychobiological adaptation in which genetic predisposition interplays with internal and/or external environmental influences such as psycho-emotional, climatic, hormonal, dietary or other factors.

Abdominal migraine

Background

Abdominal migraine (AM) is a syndrome usually recognised in childhood. The syndrome is characterised by episodic attacks of severe abdominal pain and vasomotor symptoms, nausea and vomiting. It is a poorly understood disorder largely due to a limited recognition of this condition by the medical community. However, the publication of AM diagnostic guidelines by the International Headache Society a decade ago and the recognition of AM in the Rome Classification of functional gastrointestinal disorders have helped to legitimise this disorder and facilitate research.

Overview

AM is relatively common, affecting up to 4% of the paediatric population. Whilst AM is not believed to continue into adulthood for the majority of children, it has the propensity to develop into probable migraine and recurrent abdominal pain in adulthood. The pathophysiology of this condition remains unclear and as a result treatment for this condition is suboptimal with avoidance of triggers and prophylactic treatment currently recommended when an episode begins.

Conclusion

The recognition of AM by the IHS and the Rome Foundation should help facilitate future research into the pathophysiology of this debilitating condition and as a result better treatments for AM should emerge. Randomised controlled trials should be a priority.

Coparenting Problems with Toddlers Predict Children's Symptoms of Psychological Problems at Age 7

This study examined whether coparenting during toddlerhood predicts children's later symptoms of attention deficit/hyperactivity disorder, oppositional defiant disorder, affective disorder, and somatic complaints. When children were 2 years old, 108 middle-class nonclinical families were observed in triadic interactions to assess two domains of dyadic coparenting (competitive and cooperative), as well as each parent's individual competitive behavior toward the spouse. Teachers and mothers reported children's symptoms of psychological problems at age 7. Independent of cooperative coparenting and each parents' individual harsh parenting, competitive coparenting predicted children's symptoms of ADHD and ODD. Interactions with child gender indicated that competitive coparenting predicted ADHD symptoms in boys (not in girls) and teacher-reported (not mother-reported) somatic complaints in girls (not in boys). ODD and ADHD symptoms were also predicted by fathers' (not mothers') individual competitive behaviors. The children of parents who were both low in competitive behaviors had the lowest teacher-rated symptoms of affective disorder.

The associations between preexisting mental disorders and subsequent onset of chronic headaches: a worldwide epidemiologic perspective

Although there is a significant association between preexisting depression and later onset of chronic headache, the extent to which other preexisting mental disorders are associated with subsequent onset of headache in the general population is not known. Also unknown is the extent to which these associations vary by gender or by life course. We report global data from the WHO's World Mental Health surveys (n = 52,095), in which, by means of the Composite International Diagnostic Interview-3.0, 16 mental disorders from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, were retrospectively assessed in terms of lifetime prevalence and age of onset. Frequent or severe headaches were assessed using self-reports. After adjustment for covariates, survival models showed a moderate but consistent association between preexisting mood (odds ratios [ORs] = 1.3-1.4), anxiety (ORs = 1.2-1.7), and impulse-control disorders (ORs = 1.7-1.9) and the subsequent onset of headache. We also found a dose-response relationship between the number of preexisting mental disorders and subsequent headache onset (OR ranging from 1.9 for 1 preexisting mental disorder to 3.4 for ≥5 preexisting mental disorders). Our findings suggest a consistent and pervasive relationship between a wide range of preexisting mental disorders and the subsequent onset of headaches. This highlights the importance of assessing a broad range of mental disorders, not just depression, as specific risk factors for the subsequent onset of frequent or severe headaches.

PERSPECTIVE

This study shows that there is a temporal association between a broad range of preexisting mental disorders and the subsequent onset of severe or frequent headaches in general population samples across the world.

Headache prevalence and related symptoms, family history, and treatment habits in a representative population of children in Alba, Italy

BACKGROUND

Headache is a widespread disorder in children, but little is known about the headache prevalence in northwest Italy, on less frequent migraine equivalents, family history, and treatment habits in children.

METHOD

This is an epidemiologic population-based study of a representative sample of children aged 3 to 11 years, conducted in Alba, Italy. We used a self-administered questionnaire to acquire information on gender, age, headache, possible migraine equivalents, family history for various diseases, and treatment habits.

RESULTS

We distributed the questionnaire to 1152 children, and a total of 649 questionnaires were successfully completed. In the preschool age, 10.3% (seven boys and nine girls) of children suffered from headache. In school-age children, the prevalence of headache was 31.4% (75 boys and 80 girls; 27% in 6 year olds and 41% at age 9 years). We found a significant correlation between headache and abdominal pain in the entire sample and with cyclic vomiting syndrome and dizziness in school-age children only. Headache correlated significantly with a family history of headache, thyroid diseases, diabetes, hypertension, and vascular diseases. Headache was treated with drugs, primarily paracetamol, in 60 of the 171 (35%) children who reported headache and in 61% of the children with migraine; no subjects were treated with triptans.

CONCLUSIONS

Headache is widespread in children, with a high prevalence of associated symptoms and family history for many other headache-related disorders.

Prevalence of functional gastrointestinal disorders in obese and overweight children

OBJECTIVE

To compare the prevalence of functional gastrointestinal disorders such as functional constipation (FC), functional abdominal pain (FAP), functional abdominal pain syndrome (FAPS) and irritable bowel syndrome (IBS) between a large cohort of healthy obese/overweight children and normal-weight children.

METHODS

Healthy children between the ages of 4 and 18 years were eligible for recruitment from the Yale Pediatric Primary Care clinic, Yale Adolescent clinic and a local private practice in Orange, CT, USA. Study subjects or their parents were interviewed using a questionnaire based on the ROME III standardized criteria for diagnosing functional gastrointestinal disorders. Medical records were reviewed to collect information about age, gender, height, weight, body mass index (BMI), ethnicity and chronic medical conditions. Children were classified into obese, overweight and normal-weight based on their BMI for age and gender. Data were analyzed to compare the prevalence of FC, FAP, FAPS and IBS between obese/overweight children and normal-weight children.

RESULTS

A total of 450 children (45% males) were recruited. There were 191 (42%) obese/overweight children and 259 (58%) normal-weight children. FAPS (odds ratio (OR) =2.1, 95% confidence interval (CI): 1.21-3.64, P=0.007), FC (OR=1.83, 95% CI: 1.12-2.98, P=0.01), and IBS (OR=2.59, 95% CI: 1.40-4.79, P=0.003) were significantly more prevalent in the obese/overweight children than in the normal-weight children. Of the obese/overweight children, 47% had at least one functional gastrointestinal disorder compared with 27% of the normal-weight children (P⩽0.001). Only 36% of the children with functional gastrointestinal disorders sought medical attention for their symptoms.

CONCLUSIONS

Obese/overweight children have a higher prevalence of functional gastrointestinal disorders than normal-weight children. Almost half of the obese/overweight children had at least one functional gastrointestinal disorder.

Prognostic factors for persistence of chronic abdominal pain in children

OBJECTIVES

The aim of the study was to identify prognostic factors for the persistence of chronic abdominal pain (CAP) in children.

MATERIALS AND METHODS

For this systematic review, MEDLINE, EMBASE, and PsycINFO were searched up to June 2008 for prospective follow-up studies of pediatric CAP as defined by the criteria of Apley, von Baeyer, or the Rome committee. The outcome measure of interest was persistence of CAP. Persistent CAP was considered only when the abdominal pain of children with CAP persisted during follow-up at the same level of frequency and severity. For each study the risk for bias was assessed. The evidence for prognostic factors was summarized according to a best-evidence synthesis.

RESULTS

Eight studies, which examined 17 prognostic factors, were included. Moderate evidence was found that having a parent with gastrointestinal symptoms predicts the persistence of CAP. Strong evidence was found for no association between female sex and the duration of CAP, and moderate evidence that the severity of abdominal pain does not predict persistence of CAP. There is conflicting evidence as to whether psychological factors prevent, or have no relation with, persistence of CAP.

CONCLUSIONS

Because there are few prognostic follow-up studies on pediatric CAP, the evidence for prognostic factors is limited. Physicians should ask about parental gastrointestinal problems because this is a risk factor for persistence of CAP in children. The hypothesis that psychological factors of the child predict persistence of CAP is not supported by evidence from the follow-up studies.

Factors associated with internalizing or somatic symptoms in a cross-sectional study of school children in grades 1-10

BACKGROUND

School related factors that may contribute to children's subjective health have not been extensively studied. We assessed whether factors assumed to promote health and factors assumed to have adverse effects were associated with self-reported internalizing or somatic symptoms.

METHODS

In a cross-sectional study, 230 boys and 189 girls in grades 1-10 from five schools responded to the same set of questions. Proportional odds logistic regression was used to assess associations of school related factors with the prevalence of sadness, anxiety, stomach ache, and headache.

RESULTS

In multivariable analyses, perceived loneliness showed strong and positive associations with sadness (odds ratio, 1.94, 95% CI 1.42 to 2.64), anxiety (odds ratio, 1.78, 95% CI 1.31 to 2.42), and headache (odds ratio, 1.47, 95% CI 1.10 to 1.96), with consistently stronger associations for girls than boys. Among assumed health promoting factors, receiving necessary help from teachers was associated with lower prevalence of stomach ache in girls (odds ratio, 0.51, 95% CI 0.30 to 0.87).

CONCLUSIONS

These findings suggest that perceived loneliness may be strongly related to both internalizing and somatic symptoms among school children, and for girls, the associations of loneliness appear to be particularly strong.

Childhood abdominal pain in primary care: design and patient selection of the HONEUR abdominal pain cohort

BACKGROUND

Abdominal pain in children is a common complaint presented to the GP. However, the prognosis and prognostic factors of childhood abdominal pain are almost exclusively studied in referred children. This cohort study aims at describing prognosis and prognostic factors of childhood abdominal pain in primary care. In this paper we describe methods used for data-collection and determine possible selective recruitment.

METHODS/DESIGN

We conducted an observational, prospective cohort study with a 1-year follow-up. From May 2004 to March 2006, 53 Dutch GPs recruited consecutive children aged 4-17 years with a new episode of abdominal pain not preceded by a consultation for this complaint in the previous 3 months. Participants filled in standardized questionnaires, and faeces and urine were sampled. To evaluate selective recruitment, the electronic medical records of participating GPs were retrospectively searched for eligible non-included children.

DISCUSSION

This study allows us to describe prognosis and prognostic factors of childhood abdominal pain in primary care. A total of 305 children were included of whom 142 (46.6%) met predefined criteria for chronic/recurrent abdominal pain at presentation; from the total group of eligible children identified from the electronic medical record, 27% were included. The included children were significantly younger than non-included children (mean age 8.49 and 9.20 years). In proportion to identified eligible children, significantly less children diagnosed with "gastroenteritis" (6.8%) and significantly more children with "generalized abdominal pain" (39%) were included compared to the 27% that was expected. This cohort represents young school-aged children consulting GPs for a new episode of abdominal pain, not diagnosed as gastroenteritis. Almost half of them fulfil the criteria for chronic abdominal pain at presentation.

Childhood predictors of recurrent abdominal pain in adolescence: A 13-year population-based prospective study

OBJECTIVE

To investigate maternal and child emotional symptoms, physical health problems, and negative life events measured at children's age 18 months and 12 years as potential predictors for self-reported recurrent abdominal pain (RAP) in adolescents (14 years).

METHODS

A population-based prospective study conducted at child health clinics (preventive health care) in Norway followed a cohort of 916 mothers with children from children's age 18 months until adolescence. Child self-report was obtained from 12 years of age. Outcome measure was adolescent self-reported RAP.

RESULTS

Of 456 adolescents, 58 (13%) reported RAP. Of these, 36 (62%) were girls. By multivariate analyses, the following maternal factors predicted RAP in adolescence: psychological distress at children's age 18 months (OR, 2.5; 95% CI, 1.3-4.8) and a maternal history of psychological distress at children's age 12 years (OR, 3.2; 95% CI, 1.7-6.2). The following child factors measured at age 12 years predicted RAP in adolescence: abdominal (OR, 2.5; 95% CI, 1.3-4.9) and extraintestinal pain (OR, 2.3; 95% CI, 1.2-4.4) by maternal report, self-reported frequent extraintestinal pain (OR, 2.9; 95% CI, 1.4-5.9), and self-reported depressive symptoms (OR, 2.4; 95% CI, 1.1-5.1). Negative life events and physical health in mothers and toddlers did not predict RAP.

CONCLUSIONS

This is the first cohort study that finds maternal psychological distress in early childhood to predict RAP in their offspring 13 years later. Our results support that maternal psychological distress and preadolescent children's depressive and somatic symptoms may play a role in the development of RAP.

Hypoalgesia related to elevated resting blood pressure is absent in adolescents and young adults with a history of functional abdominal pain

Elevated resting blood pressure (BP) is hypoalgesic in healthy individuals, but this effect is absent in adults with chronic somatic pain. This study tested whether BP-related hypoalgesia is similarly altered in individuals with a history of chronic visceral pain in childhood. Resting BP was assessed in 94 adolescents and young adults with a known history of childhood functional abdominal pain (FAP) and 55 comparable healthy controls. Responses to an acute heat pain stimulus were then evaluated following exposure to two laboratory stressors. A significant participant type x systolic BP (SBP) interaction (p<.005) revealed that elevated resting SBP was associated with significantly higher heat pain threshold (p<.001) in healthy controls, but was unrelated to pain threshold in the FAP group. A similar pattern was observed for heat pain tolerance, with elevated SBP linked to significantly higher pain tolerance (p<.05) in healthy controls, but unrelated to tolerance in the FAP group. Dysfunction in BP-related hypoalgesia associated with FAP was evident regardless of whether childhood FAP had resolved or still persisted at the time of laboratory testing. Subgroup analyses indicated that BP-related hypoalgesia (in healthy controls) and FAP-linked absence of this hypoalgesia was observed only among females. Result suggest that childhood visceral chronic pain may be associated with relatively long-lasting dysfunction in overlapping systems modulating pain and BP that persists even after FAP resolves. Potential implications for later hypertension risk are discussed.

Exploring psychophysiological markers of vulnerability to somatic illnesses in females

OBJECTIVE

To examine the association between biological stress regulation and somatic complaints in young girls prior to the onset of clear psychopathology such as somatization disorder.

METHODS

Salivary cortisol, heart rate variability (HRV), and negative mood were assessed in 48 12-year-old girls in response to the Trier Social Stress Test for Children (TSST-C). Parent and child report on the Children's Somatization Inventory was used to identify girls with high and low somatic complaints.

RESULTS

Girls with high levels of somatic complaints had significantly higher initial levels of cortisol, which decreased over time, and showed a trend for a more limited HRV in response to the TSST-C than girls with low levels of somatic complaints.

CONCLUSIONS

High levels of cortisol and possibly low HRV among girls with somatic complaints may interfere with flexibility in responding to typical psychosocial stressors, which may increase vulnerability to the onset of somatic illnesses in females.

Prognosis of chronic or recurrent abdominal pain in children

BACKGROUND

Chronic abdominal pain (CAP) or recurrent abdominal pain is common in childhood and is rarely associated with organic disease. With modern diagnostic technology, new organic abnormalities are found in children with CAP. Thus far a causal relation between these abnormalities and CAP has not been established. The additional prognostic value of extensive testing of children with CAP is a subject of debate.

OBJECTIVES

To investigate how often abdominal pain persists in children with CAP and to investigate whether medical tests such as laboratory tests, imaging, and endoscopy have additional prognostic value to history taking and clinical examination.

MATERIALS AND METHODS

A systematic search was conducted in MEDLINE, EMBASE, and PsycINFO for prospective cohort studies published from 1960 until October 2005. The most common medical key words for CAP were used in our search strategy. The methodological quality of studies was determined. Clinical heterogeneity between studies was analyzed. The percentages of children with abdominal pain after follow-up were pooled.

RESULTS

The search yielded 2620 citations, of which 18 studies met the inclusion criteria. In total, 1331 children were followed up for 5 years (median, range 1-29 years). In total, 29.1% (95% CI 28.1-30.2) of patients with CAP had abdominal pain after follow-up. The prognosis of CAP diagnosed clinically was similar to that diagnosed after additional medical testing.

CONCLUSIONS

CAP persisted in 29.1% (95% CI 28.1-30.2) of children. In the absence of alarming symptoms, additional diagnostic testing did not influence the prognosis of CAP.

Idiopathic Headache in Children Under Six Years of Age: A Follow‐Up Study

OBJECTIVE

To assess the evolution of idiopathic headache with early onset and to investigate the influence of early somatic disorders, "life events," and psychiatric disorders on the onset and the course of headache. We also studied the possible prognostic role of gender, headache diagnosis at onset, and history of headache in family members on the course of headache. We also investigated the applicability of the ICHD-II criteria to idiopathic headache in preschool children.

METHODS

Prospective evaluation of 25 consecutive headache patients referred before the age of 6 years. Headache diagnosis was based on the IHS 1988 criteria, on the ICHD-II criteria, and on "alternative" clinical criteria [eg, duration less than 1 hour in migraine without aura (MWA), less than 30 minutes in tension-type headache (TTH)]. All patients were assessed by a structured interview to detect early developmental disorders (eg, feeding difficulties or sleep disorders) and "life events" (eg, parents' separation and others according to DSM-IV). All patients underwent clinical observations and assessment of psychiatric comorbidity (ICD-10) by means of interviews and the Child Behaviour Check List. All the above-mentioned evaluations were performed at recruitment (T0) and at the end of the follow-up period (T1).

RESULTS

A total of 25 children with headache (12 males; 13 females) were monitored through long-term clinical follow-up (mean duration: 4.2 years; range: 2.8 to 6.6 years). The "definite" diagnosis of migraine without aura or TTH at T0 was possible in only 6/25 (24%) and 9/25 patients (36%) applying the IHS 1988 criteria and the ICHD-II criteria respectively, but in 20/25 (80%) applying the "alternative" clinical criteria. Evaluation of headache at T1 revealed: remission in 16/25 (64%) patients and persistence in 9/25 (36%). At T1, the ICHD-II diagnosis was possible in 100% of the children with headache persistence (1/9 migraine without aura and 8/9 TTH) and these diagnoses were found to be perfectly concordant with those obtained applying the "alternative criteria." Early developmental disorders were present in 11/25 children, with a significantly higher prevalence in children with headache persistence compared to children showing headache remission (78% vs. 25%; P < .05). No significant differences were found between patients with headache persistence and patients with headache remission with regard to gender, history of headache in family members, headache diagnosis at onset, psychiatric comorbidity at T0, and with regard to "life events" at both T0 and T1. Conversely, the children presenting psychiatric disorders at T1 were more frequently affected by headache than those without psychiatric disorders (59% vs. 15%; P < .05).

CONCLUSIONS

Our results suggest that the ICHD-II criteria are too restrictive to allow the classification of migraine without aura and TTH in preschool children. Nevertheless, a diagnosis based on these criteria was possible in all the patients with headache persistence at the end of several years' follow-up. We found a significant association between early somatic disorders and persistence of headache and also between the presence of psychiatric disorders at the end of follow-up and the persistence of headache. "Life events," on the other hand, while not showing a statistically significant association with the evolution of the headache, may nevertheless influence the course of the headache in some patients. Our results suggest that environmental and psychological factors play an important role in idiopathic headache with onset in preschool age, and thus that the diagnostic-therapeutic approach must take these factors into account.

Factors influencing functional abdominal pain in children

Functional gastrointestinal disorders (FGIDs) commonly affect children and are associated with short- and long-term morbidity. Although the pathogenesis of pain-related FGIDs remains incompletely understood, most investigators agree on a multifactorial etiology and the presence of an altered brain-gut interaction. A continuous interplay of genetic and environmental factors appears to shape the development of the central and enteric nervous systems. The biopsychosocial model is the current operational framework for children with FGIDs, as it recognizes the interaction between social and environmental influences and psychological and physiologic processes. The biopsychosocial model proposes that specific permutations of genetic susceptibility, early life experiences, sociocultural issues, and coping mechanisms could explain the variability in clinical presentation and outcome among individuals.

Pain Catastrophizing Scale for Francophone Adolescents: a preliminary validation

BACKGROUND

In adults, it is well known that high levels of pain catastrophizing are related to increased pain and disability as well as to heightened anxiety and depression. However, due to the lack of a measure of pain catastrophizing adapted for francophone adolescents, little is known about the role of catastrophizing in this population.

OBJECTIVES

To adapt the French version of the Pain Catastrophizing Scale (PCS) and to examine the psychometric properties and factorial structure of the PCS for Francophone Adolescents (PCS-Ado).

METHODS

The French version of the PCS was modified by a group of experts. The format of the questions was modified to be appropriate for adolescents aged between 12 and 18 years. To assess the psychometric properties of the PCS-Ado, 345 adolescents completed the PCS-Ado and questionnaires measuring depression, anxiety and intensity of pain. Twelve to 16 weeks later, participants completed the questionnaires again to examine the test-retest reliability of the PCS-Ado.

RESULTS

Results revealed a three-factor solution similar to the original PCS. In addition, results revealed that PCS-Ado had good internal consistency (PCS-Ado total: 0.85; rumination: 0.72; magnification: 0.66; helplessness: 0.74), and high test-retest reliability (r=0.73). Finally, significant correlations among catastrophizing, depression, anxiety and pain intensity support the construct validity of the PCS-Ado.

CONCLUSIONS

The results suggest that the PCS-Ado is valid and reliable with francophone adolescents. Further research is required to assess the validity of the PCS-Ado in clinical settings.

Recurrent abdominal pain in school children: effect of obesity and diet

AIMS

To study the epidemiology and some of the risk factors of childhood recurrent abdominal pain (RAP) in school age children.

METHODS

We used a questionnaire concerning socioeconomic parameters, intensity, frequency, duration, nature of RAP and anthropometric measures. We used several criteria to identify RAP and the Wong-Baker FACES scale for pain intensity and calculated the gender/age-specific body mass index (BMI) Z-score using NCHS standards. Obesity was defined as a BMI>or=95th percentile for age and gender.

RESULTS

A total of 925 children mean age of 9.5 years completed and returned the questionnaires. The prevalence of RAP was 24%; 22% among boys versus 26% among girls (p=0.28) and reached its peak among children aged 7-9 (29%) years. Children with BMI>or=95% percentile reported more RAP compared to those not obese (33.3% vs. 22.5%) (OR=1.8, p=0.01). There was an inverse correlation between fruit consumption and RAP prevalence with 20% among children reporting more than three serving of fruit per week compared to 40% of those who did not consume any fruits (p<0.002). Logistic regression analysis confirmed BMI>or=95th percentile and low consumption of fruits are significant risk factors for RAP.

CONCLUSIONS

There is a significant association between RAP and obesity and both conditions are prevalent among children in this population. Understanding more about the co-morbidity between RAP and obesity could have important implications on RAP management and treatment.

Pain in Adolescent Psychiatric Patients

BACKGROUND

  Little is known about the extent of pain among adolescent psychiatric patients, and the relationships with psychosocial factors and psychiatric symptoms.

METHOD

  A representative sample of 129 adolescent patients were assessed with measures including the Youth Self-Report, the Mood and Feelings Questionnaire, and instruments assessing self-perceptions, coping styles, stresses, sociodemographic factors, and childhood abuse.

RESULTS

  More than half of the adolescents (54%) reported to be bothered currently by frequent pain. Frequent pain correlated with depression, self-harm, suicide attempt, and with ruminative and emotion oriented coping. Adolescents suffering from frequent pain had more often experienced childhood abuse/neglect. A stepwise multiple regression analysis revealed that depression, alcohol intoxication and childhood neglect were the strongest concurrent predictors of frequent pain.

CONCLUSIONS

  Clinicians should ask child and adolescent psychiatric patients about pain, and be aware of possible connections with abuse/neglect, depression and suicidality.

Prevalence of recurrent complaints of pain among Greek schoolchildren and associated factors: a population-based study

AIM

To determine the prevalence of recurrent complaints of pain (RCP) in Greek children, and to examine associations with socio-demographic characteristics and psychosocial factors.

METHODS

Cross-sectional study comprising a nationally representative population of 8130 7-y-old Greek schoolchildren. Data were collected by mailed questionnaires (response rate 89%). RCP was defined as present if at least one of the complaints of headache, abdominal pain or limb pain occurred at least once a week.

RESULTS

The RCP prevalence rate was 7.2%, with significant gender differences (8.8% of girls, 5.7% of boys; p<0.001). RCP was significantly positively associated with a chronic health problem among the children, frequent change of residence, poor school performance, often watching TV and rarely playing with other children. There were no statistically significant associations of RCP with family structure and socio-economic status.

CONCLUSION

The results are indicative of the prevalence of RCP in Greek schoolchildren. This study enlightens the psychosocial component of RCP and emphasizes the importance of gathering information on children's social background in medical settings.

Family history of irritable bowel syndrome is the major determinant of persistent abdominal complaints in young adults with a history of pediatric recurrent abdominal pain

AIM: To assess the late outcome of teen-agers with a previous history of recurrent abdominal pain (RAP) or irritable bowel syndrome (IBS).

METHODS: A group of 67 children with RAP referred to the department from January 1986 to December 1995 was followed up between 5 and 13 years after the initial diagnosis by means of a structured telephone interview. We hypothesized that those patients with persistent adult IBS-like symptoms would be significantly more likely to report a family history of IBS in comparison with adults with no persistent abdominal complaint.

RESULTS: Out of the 52 trackable subjects, 15 were found to present IBS-like symptoms at follow-up (29%) whereas the majority (37 subjects) did not. Subjects with IBS-like symptoms were almost three times more likely to present at least one sibling with similar symptoms compared to subjects not complaining (40.0% vs 16.0%), respectively (P < 0.05 at Student t test). Subjects with IBS-like symptoms also reported a higher prevalence of extra-intestinal symptoms, such as back pain, fibromyalgia, headache, fatigue and sleep disturbances.

CONCLUSION: The study confirms previous obser-vations indicating that pediatric RAP can predict later development of IBS. The latter appears to be greatly influenced by intrafamilial aggregation of symptoms, possibly through the learning of a specific illness behavior.

Primary headaches in preschool age children: clinical study and follow-up in 163 patients

Although headache frequency is increasing in preschool age children, an extensive evaluation of the clinical features in affected patients has yet to be achieved. This retrospective study examined 243 patients who were separately analysed in two distinct groups according to the age of onset and the age of first clinical evaluation. Group 1 included preschool age children, while Group 2 consisted of pubertal age patients. In all the patients the importance of a positive family history for headache as a risk factor was confirmed. In addition, when compared with Group 2, Group 1 showed greater male gender prevalence and earlier onset of the attacks. Regarding clinical features, in Group 1, compared with Group 2, the attack duration was shorter with lower symptom association such as photo- or phonophobia, nausea and no pain increase during physical activity. In the same group, tension-type headache was the predominant diagnosis, in contrast to the high migraine prevalence of Group 2. This study also showed that the International Headache Society 1988 classification criteria are not fully adequate for juvenile headaches. In fact, the headaches of more than 10% of patients in Group 1 still remained unclassifiable, while those of all the subjects in Group 2 were properly classifiable.

Extracephalic tenderness and pressure pain threshold in children with headache

BACKGROUND

Sensitisation of the pain detection system has been suggested to be involved in the pathogenesis of recurrent headache. In adults, increased sensitivity to pain has been found in patients with chronic tension type headache. Children with migraine or with unspecific headache report non-headache pains and interictal pericranial muscular tenderness more often than headache-free children.

OBJECTIVE

To study if children with different types of headache report non-headache pain more often than children with no headache and if extracephalic muscular tenderness is different in children with headache in comparison to headache-free children. To find out if interval to the headache episode has influence on the extracranial muscular tenderness.

DESIGN

A population-based sample of 13-year-old children with migraine (n=48), episodic tension type headache (61) or no headache (59) were interviewed for the occurrence and characteristics of headache and fulfilled a questionnaire on non-headache pain. A structured manual palpation test on muscular tenderness and a pain threshold measurement were done on seven cephalic and three extracephalic points.

RESULTS

Children with migraine reported other pains, especially stomach pain and limb pain more often than children with episodic tension type or no headache. There were no significant differences in the extracephalic muscular tenderness or in the pressure pain thresholds between the three groups.

CONCLUSIONS

Children with migraine experience more non-headache pains than children with episodic tension type headache and with no headache. However, neither children with migraine nor children with episodic tension type headache show increased interictal extracephalic muscular sensitivity for palpation.

The epidemiology of childhood recurrent abdominal pain in Western countries: a systematic review

OBJECTIVE

Recurrent abdominal pain (RAP) of childhood is a common problem encountered by clinicians. The aim of this study was to systematically review published literature about the prevalence, incidence, natural history, and co-morbid conditions of childhood RAP in western countries.

METHODS

A computer-assisted search of MEDLINE, EMBASE, and Current Contents/Science Edition databases was performed. Study selection criteria included: (1) United States and European population and school-based samples of children; (2) diagnostic criteria of RAP; and (3) published in full manuscript form in English. Data were extracted, tabulated, and presented in descriptive form.

RESULT

The prevalence of RAP ranged from 0.3 to 19% (median 8.4; IQR 2.3-14.7). Published studies in children demonstrate a higher prevalence of RAP in females, with the highest prevalence of symptoms between 4 and 6 yr and early adolescence. Identified studies demonstrated associations between RAP and the child's familial and socioeconomic environment. In addition, childhood RAP was reported to be associated with psychological co-morbidity in childhood and adulthood. Population/school-based studies have not, however, established the incidence of this disorder, what features predict long-standing symptoms, or whether RAP is a risk factor for adult functional bowel disorders.

CONCLUSION

RAP is a common complaint of childhood with associated familial, psychological, and co-morbid conditions. Epidemiologic studies of RAP in children may offer information on the evolution of functional bowel disorders through the lifespan.

Have there been changes in children's psychosomatic symptoms? A 10-year comparison from Finland

OBJECTIVES

The aims of the study were to determine whether the prevalence of children's somatic symptoms, such as headache, abdominal pain, other pain, and nausea and vomiting, changed from 1989 to 1999 and to study the similarity of parents' and children's reports of the child's symptoms. Furthermore, the aims were to explore possible comorbidity in somatic symptoms and to investigate the associations between somatic and psychiatric symptoms.

METHODS

Two cross-sectional, representative samples were compared. All children born in 1981 (1989 sample, n = 985) and 1991 (1999 sample, n = 962) and living in selected school districts in southwest Finland served as study samples. The response rate for the 1989 sample was 95% and that for the 1999 sample was 86%. Both children and parents were asked about the children's somatic symptoms, whereas parents, children, and teachers were asked about psychiatric symptoms. To study psychiatric symptoms, the Children's Depression Inventory and Rutter's parent and teacher scales were used.

RESULTS

The prevalence of frequent headaches and abdominal pain increased somewhat from 1989 to 1999. Parents often failed to recognize their children's psychosomatic problems. Child-reported somatic symptoms were associated with conduct and hyperactivity symptoms, in addition to a previously well-documented association with depression. In associations between somatic symptoms and psychiatric symptoms, there were some differences between the 1989 and 1999 samples.

CONCLUSIONS

In clinical work, questions about somatic and psychiatric symptoms should also be addressed to children themselves, because parents and teachers do not always recognize children's symptoms. When somatic problems are being evaluated, psychiatric symptoms should be asked about, and vice versa. More research is needed to explore the reasons for the increased prevalence of somatic symptoms and their associations with psychiatric symptoms.

Development of a multidimensional measure for recurrent abdominal pain in children: population-based studies in three settings

OBJECTIVE

Recurrent abdominal pain (RAP) is a common problem in children and adolescents. Evaluation and treatment of children with RAP continue to challenge physicians because of the lack of a psychometrically sound measure for RAP. A major obstacle to progress in research on RAP has been the lack of a biological marker for RAP and the lack of a reliable and valid clinical measure for RAP. The objectives of this study were (1) to develop and test a multidimensional measure for RAP (MM-RAP) in children to serve as a primary outcome measure for clinical trials, (2) to evaluate the reliability of the measure and compare its responses across different populations, and (3) to examine the reliabilities of the measure scales in relation to the demographic variables of the studied population.

METHODS

We conducted 3 cross-sectional studies. Two studies were clinic-based studies that enrolled children with RAP from 1 pediatric gastroenterology clinic and 6 primary care clinics. The third study was a community-based study in which children from 1 elementary and 2 middle schools were screened for frequent episodes of abdominal pain. The 3 studies were conducted in Houston, Texas. Inclusion criteria for the clinic-based studies were (1) age of 4 to 18 years; (2) abdominal pain that had persisted for 3 or more months; (3) abdominal pain that was moderate to severe and interfered with some or all regular activities; (4) abdominal pain that may or may not be accompanied by upper-gastrointestinal symptoms; and (5) children were accompanied by a parent or guardian who was capable of giving informed consent, and children over the age of 10 years were capable of giving informed assent. The community-based study used standardized questionnaires that were offered to 1080 children/parents from the 3 participating schools; 700 completed and returned the questionnaires (65% response rate). The questionnaire was designed to elicit data concerning the history of abdominal pain or discomfort. A total of 160 children met Apley's criteria and were classified as having RAP. Inclusion criteria were identical to those criteria for the clinic-based studies. Participating children in the 3 studies received a standardized questionnaire that asked about socioeconomic variables, abdominal pain (intensity; frequency; duration; nature of abdominal pain, if present, and possible relationships with school activities; and other upper gastrointestinal symptoms). We used 4 scales for the MM-RAP: pain intensity scale (3 items), nonpain symptoms scale (12 items), disability scale (3 items), and satisfaction scale (2 items). Age 7 was used as a cutoff point for the analysis as the 7-year-olds have been shown to exhibit more sophisticated knowledge of illness than younger children.

RESULTS

A total of 295 children who were aged 4 to 18 years participated in the study: 155 children from the pediatric gastroenterology clinics, 82 from the primary care clinics, and 58 from the schools. The interitem consistency (Cronbach's coefficient alpha) for the pain intensity items, nonpain symptoms items, disability items, and satisfaction items were 0.75, 0.81, 0.80, and 0.78, respectively, demonstrating good reliability of the measure. The internal consistencies of the 4 scales did not significantly differ between younger (< or =7 years) and older (>7 years) children. There was also no significant variation in the coefficient alpha of each of the 4 scales in relation to gender or the level of the parent's education. Reliability was identical for the pain-intensity items (0.74) among children who sought medical attention from primary care or pediatric gastroenterology clinics. The intercorrelations of factor scores among the 4 scales showed a strong relationship among the factors but not high enough that correlations would be expected to be measuring the same items. The results of the factor analysis identified 5 components instead of 4 components representing the 4 scales. The 12 items of the nonpain symptoms scale were classified into 2 components; 1 component included heartburn, burping, passing gas, bloating, problem with ingestion of milk, bad breath, and sour taste (nonpain symptoms I), and the other included nausea/vomiting, diarrhea, and constipation (nonpain symptoms II). The program ordered the 5 components on the basis of the percentage of the total variance explained by each component and consequently by the strength of each components in the following order: nonpain symptoms I, pain intensity, pain disability, satisfaction, and nonpain symptoms II. Of the 20 items that composed the MM-RAP, 17 met the inclusion criteria of having a correlation of > or =0.40 on the primary factor analyses. The 3 items that assessed pain intensity met the inclusion criteria as well as the 2 items that assessed satisfaction. Two of the 3 items that assessed disability met the inclusion criteria; however, the missed school item did not. The sleep problem and the loss of appetite items in the nonpain items also did not meet the inclusion criteria in both components of the nonpain symptoms scale. However, the loss of appetite item met the inclusion criteria in the disability scale with a correlation of 0.6. The 2 items that did not meet the inclusion criteria (missed school days and sour taste) will be eliminated in the revised measure for RAP.

CONCLUSION

The MM-RAP demonstrated good reliability evidence in population samples. Children who have RAP and are seen at pediatric gastroenterology or primary care pediatric clinics have similar responses, showing that the measure performed well across several populations. Age did not affect the reliability of responses. The MM-RAP included 4 dimensions, each with several items that may identify disease-specific dimensions. In addition, dividing the nonpain symptoms scale into 2 components instead of 1 component could assist in creating a disease-specific measure. The present study focused exclusively on developing the multidimensional measure for RAP in children that could assist physicians in evaluating the efficacy of RAP treatment independent of psychological evaluations. In addition, the measure was designed for use in clinical trials that evaluate the efficacy of RAP treatment and to allow comparison between intervention studies. In conclusion, we were able to identify 4 dimensions of RAP in children (pain intensity, nonpain symptoms, pain disability, and satisfaction with health). We demonstrated that these dimensions can be measured in a reliable manner that is applicable to children who experience RAP in various settings.

Externalizing problem behaviors and headache: a follow-up study of adolescent Finnish twins

OBJECTIVE

To examine the association of teacher- and parent-rated behavior with headache in a prospective follow-up study of adolescent Finnish twins.

METHODS

Questionnaire data were collected during 1995-2001 from a nationwide sample of Finnish families of 11-year-old twins who were born 1983-1987 (n = 5393) and again at age of 14. Psychological factors were measured by using parents' and teachers' ratings of a 37-item multidimensional rating instrument at the ages of 11 and 14.

RESULTS

At age 11, headache frequency (5 categories) was associated with total scales of externalizing and internalizing problem behaviors and adaptive behaviors, assessed by parents, but only with externalizing problem behaviors assessed by teachers. Results were similar at age 14. The incidence of at least monthly headache between the ages of 11 and 14 years was predicted by externalizing problem behaviors and 2 subscales of adaptive behaviors: constructiveness and poor compliance. In twin pairs discordant for headache, externalizing and internalizing problem behaviors were more common among headache sufferers than among headache-nonsufferers. Headache-discordant monozygotic co-twins confirmed the association of externalizing problem behaviors with headache.

CONCLUSIONS

The frequency of adolescents' headache is predicted by psychological factors, especially by externalizing problem behaviors. This seems to be independent of genetic or familial influences on behavior and headache. Behavioral problems may be a sign of worsening of headache or vice versa.

Citalopram treatment of pediatric recurrent abdominal pain and comorbid internalizing disorders: an exploratory study

OBJECTIVE

To assess the potential efficacy, tolerability, and safety of citalopram in the treatment of functional pediatric recurrent abdominal pain and comorbid internalizing disorders.

METHOD

Twenty-five clinically referred children and adolescents with recurrent abdominal pain aged 7 to 18 years, inclusive, participated in a 12-week, flexible-dose, open-label trial of citalopram. Primary outcome measure was the Clinical Global Impression Scale-Improvement, with responders defined by ratings of 1 (very much improved) or 2 (much improved). Secondary measures included self- and parent reports of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment. Side effects were assessed using a standardized checklist. Data were analyzed using an intent-to-treat format and the last observation carried forward procedure.

RESULTS

Twenty-one subjects (84%) were classified as responders (Clinical Global Impression Scale-Improvement score < or =2). Citalopram was generally well tolerated. Four subjects withdrew prematurely, one due to reported visual side effects. Ratings of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment all improved significantly over the course of the study compared with baseline.

CONCLUSIONS

Citalopram is a promising treatment for functional pediatric recurrent abdominal pain and deserves additional study with a randomized, placebo-controlled clinical trial.

Parental reports of somatic symptoms in preschool children: prevalence and associations in a Spanish sample

OBJECTIVE

To document prevalence and associations of somatic symptoms in Spanish preschool children.

METHOD

Subjects were 3- to 5-year-olds attending nurseries (8 urban, 30 rural). Parental questionnaires (response rate 77%) were used to inquire about somatic symptoms in the child in the 2 weeks prior to assessment, about preschool absence and pediatric help-seeking, chronic family health problems, and recent stressful life events for the child. Parents completed questionnaires on child psychopathology (Early Childhood Inventory 4) and their own mental health (General Health Questionnaire). Children who were reported as complaining of symptoms frequently (four or more times) were compared to noncomplaining children.

RESULTS

Parents reported that 452 of the 807 (56%) children complained of somatic symptoms at least once, significantly more so in urban than in rural areas. Frequent somatic complaints were reported for 165 of the 807 (20%) (abdominal pains 7.9%, tiredness 5.7%, leg pains 4%, headaches 2%, dizziness 0.4%). There were significant associations of frequent symptom reporting with days off preschool and pediatric clinic attendance, with emotional and behavioral symptoms in children, mental distress in parents, and urban abode.

CONCLUSIONS

Somatic symptoms are common in preschool children. Results point to family influences.

Recurrent abdominal pain, anxiety, and depression in primary care

OBJECTIVE

The prevalence of psychiatric disorder in children and adolescents with functional recurrent abdominal pain (RAP) is unknown. Our aim was to determine whether RAP is associated with psychiatric symptoms and disorders, anxious temperament, and functional impairment in pediatric primary care.

METHODS

Children and adolescents who were 8 to 15 years of age, inclusive, and presented with RAP (N = 42) or for routine care in the absence of recurrent pain (N = 38) were identified by a screening procedure in pediatric primary care office waiting rooms and recruited to participate in a case-control study. Outcome measures were psychiatric diagnoses generated by standardized psychiatric interview administered blind to subject status and self, parent, and clinician ratings of child psychiatric symptoms, temperamental traits, and functional status.

RESULTS

RAP patients were significantly more likely to receive a diagnosis of a psychiatric disorder, with a categorical anxiety disorder in 33 (79%) and a depressive disorder in 18 patients (43%), and higher levels of anxiety and depressive symptoms, temperamental harm avoidance, and functional impairment than control subjects. Anxiety disorders (mean age of onset: 6.25 [standard deviation: 2.17] years) were significantly more likely to precede RAP (mean age of onset: 9.17 [standard deviation: 2.75] years) in patients with associated anxiety.

CONCLUSIONS

Youths who present with RAP in primary care deserve careful assessment for anxiety and depressive disorders. Future studies should examine treatments that are proved to be efficacious for pediatric anxiety and/or depressive disorders as potential interventions for RAP. Longitudinal, family, and psychobiological studies are needed to illuminate the nature of observed associations among RAP, anxiety, and depression.

Caffeine-induced headache in children and adolescents

Caffeine is the most widely used behaviourally active substance. Excessive caffeine consumption, mostly in the form of coffee and tea, is a well-recognized cause of headache or migraine, and withdrawal can cause headache. Nevertheless, caffeine abuse headache is not listed as a separate category in the International Headache Society classification, 1988. We report our experience with children and adolescents with daily or near-daily headache and excessive consumption of caffeine in the form of cola drinks. Over a period of 5 years we have encountered, in a tertiary headache clinic in a general hospital, 36 children and adolescents (17 girls and 19 boys) with daily or near-daily headache related to excessive caffeine intake in the form of cola drinks. The mean age of the subjects was 9.2 years (range 6-18) and mean headache duration was 1.8 years (range 0.6-5). All were heavy cola drinks consumers; at least 1.5 L of cola drinks per day (192.88 mg of caffeine daily), and an average of 11 (range 10.5-21) L of cola drinks a week, which amounts to 1414.5 mg of caffeine (range 1350.1-2700.3). Patients were encouraged to achieve gradual withdrawal from cola drinks, which led to complete cessation of all headaches in 33 subjects, whereas one boy and two adolescent girls continued to suffer from migraine without aura not frequent enough to justify prophylactic medication. Children and adolescents with high daily caffeine consumption in the form of cola drinks may suffer from caffeine-induced daily headache. Gradual withdrawal can be achieved without withdrawal headache and with complete disappearance of the induced chronic daily headache.

Entwicklungspsychopathologie rekurrierender Bauchschmerzen und somatoformer Störungen

Zusammenfassung. Der Beitrag untersucht aus einer entwicklungspsychopathologischen Perspektive die störungs- und entwicklungsbezogenen Assoziationen zwischen rekurrierendem Bauchschmerz und somatoformer Störung sowie komorbiden Angststörungen bzw. Depression. Dazu werden eingangs Pfade des Übergangs von Störungsbildern der Eltern auf das Kind (Transmission) sowie die Stabilität bzw. Variabilität rekurrierender Bauchschmerzen und somatoformer Störungen vom Kindesalter zum Erwachsenenalter untersucht. Ein entwicklungspsychopathologisches Phasenmodell zeigt eine Sequenz von vier Etappen der Störungsentwicklung auf. Als Mediatoren eines ungünstigen Verlaufs werden Lernprozesse, Faktoren der kognitiv-behavioralen Schmerz- und Beschwerdeverarbeitung, beschwerdebezogene Copingstrategien sowie dysfunktionale Interaktionsmuster innerhalb der Familie sowie in der Arzt-Patient-Beziehung analysiert. Entwickelt sich eine Komorbidität mit einer Angststörung oder Depression, so zeigen diese Patienten störungsbedingt ein zusätzlich erhöhtes Risiko der verzerrten Verarbeitung abdomineller Beschwerden und Schmerzen.

Abdominal migraine: evidence for existence and treatment options

There is evidence to suggest that, in children, episodic abdominal pain occurring in the absence of headache may be a migrainous phenomenon. There are four separate strands of evidence for this: the common co-existence of abdominal pain and migraine headaches; the similarity between children with episodic abdominal pain and children with migraine headaches, with respect to social and demographic factors, precipitating and relieving factors, and accompanying gastrointestinal, neurological and vasomotor features; the effectiveness of nonanalgesic migraine therapy (such as pizotifen, propanolol, cyproheptadine and the triptans) in abdominal migraine; and the finding of similar neurophysiological features in both migraine headache and abdominal migraine. Abdominal migraine is rare, but not unknown, in adults. Many families are content with a diagnosis and reassurance that the episodes, though distressing, are not the result of serious pathology. Some patients respond to simple dietary and other prophylactic measures. There is scant evidence on which to base recommendations for the drug management of abdominal migraine. What little literature exists suggests that the antimigraine drugs pizotifen, propanolol and cyproheptadine are effective prophylactics. Nasal sumatriptan (although not licensed for pediatric use) may be effective in relieving abdominal migraine attacks.

Changes in headache prevalence between pre-school and pre-pubertal ages

The prevalence rates of headache in first-born children were determined at the ages of 6 and 12 years in over 1000 families. A headache questionnaire was mailed to 1132 families when the children were 6 years old, and to 1126 families when the children were 12 years old. Seven hundred and ninety-eight families responded to both questionnaires. The prevalence of headache before the 6 months preceding the questionnaire ('previous headache') was 19% when the children were 6 years of age and 31% when the children were 12 years of age. The corresponding prevalences of headache during the 6 months immediately proceeding the questionnaire ('present headache') were 16% and 19%. Variation in occurrence of headache was high during follow-up years. Maternal frequent headache (> or = 1/month) was significantly associated with the increase in prevalence of present headache in boys between the ages of 6 and 12 years. Frequent headache in mothers, fathers and siblings, and the occurrence of chronic illness, were also significantly associated with headache in the 12-year-old children.

Adult outcomes of pediatric recurrent abdominal pain: do they just grow out of it?

OBJECTIVE

To determine whether medically unexplained recurrent abdominal pain (RAP) in childhood predicts abdominal pain, irritable bowel syndrome (IBS), other somatic complaints, and psychiatric symptoms and disorders in young adulthood.

METHODS

A sample of 28 young adults evaluated for RAP between the ages of 6 and 17 years were compared with 28 individually matched former childhood participants in a study of tonsillectomy and adenoidectomy. RAP caseness was established by structured retrospective chart review requiring agreement by 2 independent reviewers. Standardized assessments of abdominal pain, IBS, other somatic symptoms, psychopathology, perceived health, and history of maltreatment were performed an average of 11.1 years after the index visit.

RESULTS

Former RAP patients were significantly more likely than controls to endorse anxiety symptoms and disorders, hypochondriacal beliefs, greater perceived susceptibility to physical impairment, poorer social functioning, current treatment with psychoactive medication, and generalized anxiety in first degree relatives. There were trends suggesting associations between childhood RAP and lifetime psychiatric disorder, depression, migraine, and family history of depression, but group differences on abdominal pain, IBS, other somatic symptoms, and history of maltreatment were not statistically significant.

CONCLUSIONS

There is a strong and relatively specific association between childhood RAP and anxiety in young adulthood. Affected children may be at special risk to perceive physical symptoms as threatening, and should be evaluated for psychiatric disorder on initial presentation.
