Medically unexplained symptoms in children and adolescents

A dyadic perspective on parent-child dyadic coping in children with a chronic condition

OBJECTIVE

In this study, we examined the extent to which parents and their children with a chronic condition communicate their stress to one another and whether stress communication is associated with different forms of dyadic coping.

METHODS

In a sample of 239 parent-child dyads, self-reported stress communication and different forms of perceived dyadic coping (i.e., emotion-oriented, problem-oriented, and negative dyadic coping) were assessed using a cross-sectional design.

RESULTS

We first found that children's stress communication was positively associated with more positive (r = 0.28, p < .001) and less negative dyadic coping responses by children (r = -0.22, p < .001). Children's stress communication was also associated with more positive (r = 0.52, r = 0.45, p's < 0.001), and less negative dyadic coping responses by parents (r = -0.19, p < .001). Using dyadic data of children with a chronic condition and their parents, we found that more stress communication of children was associated with healthier coping responses of both children (perceived emotion-oriented dyadic coping: β = 0.23, p < .001) and parents (perceived emotion-oriented dyadic coping: β = 0.33, p < .001; perceived problem-oriented dyadic coping: β = 0.22, p < .001).

CONCLUSION

This underscores the importance of communication and adaptive coping strategies of parents and children in the context of a child's chronic condition. These findings may help us find ways to support children and their parents to optimally communicate about and deal with their stress.

The kynurenine pathway of tryptophan metabolism in abdominal migraine in children - A therapeutic potential?

BACKGROUND

Abdominal migraine (AM) is a clinical diagnosis specified by Rome IV and ICHD III as a functional gastrointestinal disease (FGID) and a migraine associated syndrome, respectively. Abdominal migraine in childhood and adolescence may continue with migraine headaches in adulthood. This disease is undiagnosed and undertreated, and thus far the FDA has not approved any drug for AM treatment. It was shown that changes in the kynurenine (KYN) pathway of tryptophan (TRP) metabolism played an important role in the pathogenesis and treatment of FIGDs and associated mood disorders. Changes in the KYN pathway were shown in migraine and therefore it may be involved in AM pathogenesis.

FINDINGS

Abdominal migraine reflects an impairment in the communication within the gut-brain axis. Treatment approaches in AM are based on the experience of physicians, presenting personal rather than evidence-based practice, including efficacy of some drugs in adult migraine. Non-pharmacological treatment of AM is aimed at preventing or ameliorating AM triggers and is based on the STRESS mnemonic. Metabolic treatments with riboflavin and coenzyme Q10 were effective in several cases of pediatric migraine, but in general, results on metabolic treatment in migraine in children are scarce and nonconclusive. Modulations within the KYN pathway of TRP metabolism induced by changes in TRP content in the diet, may ameliorate FGIDs and support their pharmacological treatment. Pharmacological manipulations of brain KYNs in animals have brought promising results for clinical applications. Obese children show a higher headache prevalence and may be especially predisposed to AM, and KYN metabolites showed an alternated distribution in obese individuals as compared with their normal-weight counterparts.

CONCLUSIONS

In conclusion, controlled placebo-based clinical trials with dietary manipulation to adjust the amount of the product of the KYN pathway of TRP metabolism are justified in children and adolescents with AM, especially those with coexisting obesity. Further preclinical studies are needed to establish details of these trials.

Should pediatric cardiologists refer all patients with unexplained chest pain to a psychiatrist?

OBJECTIVE

The present study aimed to investigate the relationship between unexplained chest pain in children with parents' mental problems, parental attitudes, family functionality, and the child's mental problems.

MATERIAL AND METHOD

A total of 433 children (between 11 and 18 years of age) applied to the Pediatric Cardiology Outpatient Clinic due to chest pain in the last year. A clinical interview was conducted by a child psychiatrist with 43 patients and 33 controls included in the study due to unexplained chest pain.

RESULTS

Family history of physical illness was significantly higher in the chest pain group. When evaluated in terms of psychosocial risk factors, life events causing difficulties, derangement in the family, loss of a close person, and exposure to violence were statistically significantly higher in the group with chest pain. Mental disorders were observed in 67.4% of the children in the chest pain group as a result of the clinical interview. The total score of the DSM-5 somatic symptoms scale, which evaluates other somatic complaints in the chest pain group, was also significantly higher. When the family functions of both groups were evaluated, communication, emotional response, behaviour control, and general functions sub-dimensions were statistically significantly higher in families in the chest pain group.

CONCLUSION

We recommend that psychiatric evaluation be included in diagnostic research to prevent unnecessary medical diagnostic procedures in children describing unexplained chest pain, as well as to prevent the potential for diagnosing mental disorders in both children and adults.

Diagnostic uncertainty in patients, parents, and physicians: a compensatory control theory perspective

Medical diagnoses offer a structure by which psychological uncertainty can be attenuated, allowing patients to diminish psychological threats and focus on health prognosis. Yet when no diagnosis can be made, patients may experience diagnostic uncertainty - perceiving the medical field as unable to provide an accurate explanation of the cause of their health problems. This review examines the psychological threat that diagnostic uncertainty imposes on individuals' need for control and understanding, and the resulting consequences experienced by patients, parents of pediatric patients, and physicians. Using compensatory control theory as a framework, we propose a taxonomy of behaviors that people may adopt in order to regain control in the face of diagnostic uncertainty and to reaffirm that the world is not random and chaotic. To manage diagnostic uncertainty, people may bolster their personal agency, affiliate with external systems they see as acting in their interest, affirm clear connections between behaviors and outcomes, and affirm nonspecific epistemic structure. Diagnostic uncertainty is approached from the perspectives of patients, parents of pediatric patients, and physicians, demonstrating how each group responds in order to maintain a sense that the world has structure and is not random. Discussion centers on moderators, limitations, and implications for clinical practice.

Trends in physical health complaints among adolescents from 2014 - 2019: Considering screen time, social media use, and physical activity

The rising rates of physical and mental health complaints among adolescents observed in many countries have coincided with an increased time spent on screen-based devices, including social media use. We sought to document recent trends in physical health complaints (PHC) and whether co-occurring trends in screen time, social media use, and physical activity may account for these trends. To achieve these aims, we used data from the nationwide Ungdata surveys conducted annually at the municipality level in Norway, comprising 419,934 adolescents aged 13-18 from six survey years (2014-2019). Six items assessed PHC, including neck and shoulder pain, headache, and abdominal pain, during the past month. To account for the nesting structure of Ungdata, and to exploit the variation within and between municipalities, we used multilevel analyses with adolescents nested in municipality-years (n = 669), nested in municipalities (n = 345). We found a small to moderate linear increase in number of PHC among boys and girls from 2014 to 2019. Screen time and social media use moderately attenuated the trend for girls, and to a lesser extent for boys. Screen time and social media use were further positively associated with PHC across the between and within-municipality levels, and social media use was more strongly associated with PHC for girls than boys across all levels of analysis. A similar pattern emerged when considering each symptom individually. The results suggest that the prevalence of PHC rose in tandem with a group-level shift towards higher screen time and social media use. Moreover, the results indicate that higher screen time and social media use may have led to changes in the youth culture with potential consequences for adolescents' well-being.

The associations between social environment and adolescents’ psychosomatic health: An ecological perspective

Objectives

It has been known that social environments are associated with adolescents’ health. However, the complex relationship between diverse types of social environments and adolescents’ psychosomatic heath remained unclear. Thus, using an ecological perspective, the current study aimed to examine the associations between social environment and adolescents’ psychosomatic health.

Methods

We used the data from the Health Behavior in School-aged Children (HBSC) project conducted in the Czech Republic in 2018. A total of 13377 observations were included.

Results

The region, as a macrosystem, could not explain the variance in adolescents’ psychological and somatic health. The quality of neighborhood environment (exosystem) was significantly related to adolescents’ psychological and somatic health. At the microsystem level, teacher support had stronger, family support had weaker, and peer support had no association with psychological and somatic health. At the mesosystem level, the interactions between family, teacher, and friend support were negligible for adolescents’ psychological and somatic health.

Conclusions

The results underscore the importance of teachers’ support and neighborhood environment for adolescents’ psychosomatic health. Therefore, the findings suggest the need to improve teacher-adolescent relationships and the neighborhood community quality.

Somatization in Adolescents With Persistent Symptoms After Concussion: A Retrospective Chart Review

OBJECTIVE

After concussion, approximately 30% of adolescents experience symptoms that persist beyond 1 month postinjury. For some, these symptoms affect functioning, development, and quality of life. Somatization, where psychological distress contributes to physical symptoms, may contribute to persistent symptoms after concussion in some adolescents. Understanding how clinicians identify somatization in adolescents with persistent symptoms after concussion in practice is a critical next step in improving our understanding, identification, and subsequent treatment of somatization in this patient population. To address this, the investigators assessed and compared characteristics of adolescents with persistent symptoms after concussion with and without clinician-identified somatization.

METHODS

Participants were adolescents (N=94) referred for persistent symptoms after concussion to a specialty youth concussion clinic between January 2016 and May 2018. A retrospective chart review extracted demographic and injury characteristics, symptoms after concussion, school attendance, premorbid experiences, mental health, and medical service use. Participants with physician-identified somatization were compared with those without physician-identified somatization on these measures.

RESULTS

Adolescents with identified somatization had more severe and atypical neurological and psychiatric symptoms after concussion and more postinjury impairment in school attendance, were more likely to have a history of premorbid chronic pain or medically unexplained symptoms, and obtained more neuroimaging and health care after injury compared with those unaffected by somatization. They did not differ in mood or anxiety symptom self-reports.

CONCLUSIONS

This study identified characteristic differences and similarities in adolescents with and without clinician-identified somatization after a prolonged concussion recovery. These findings have the potential to improve clinical identification of somatization in youths following a concussion and may aid in treatment among this demographic group.

Nonproductive thoughts, somatic symptoms and well-being in adolescence: testing the moderator role of age and gender in a representative study

Background

Previous findings suggest a female preponderance in nonproductive thoughts -rumination and worry-, but studies on gender differences in the strength of the relationship between nonproductive thoughts, somatic symptoms and subjective well-being are scarce. Our aim was to test whether gender and age would moderate these associations.

Methods

1572 adolescents were involved in this representative cross-sectional study (770 boys; mean age = 15.39; SD = 2.26 years). Nonproductive thoughts were measured by Nonproductive Thoughts Questionnaire for Children (NPTQ-C), somatic symptoms were assessed by Somatic Complaint List (SCL), while Mental Health Continuum-Short Form (MHC-SF) was used to measure subjective well-being. To assess the moderation effects of age and gender on the relationship between nonproductive thoughts, somatic symptoms and well-being, four multiple indicator multiple causes (MIMIC) models were defined.

Results

Our results suggested that higher rates of nonproductive thoughts predicted a higher level of somatic symptoms and a lower level of subjective well-being. The analyses revealed that although nonproductive thoughts were strongly and equally associated with somatic symptoms among boys and girls, age was a significant moderator. Gender also moderated the relationship between nonproductive thoughts and subjective well-being.

Conclusions

Our results support the importance of nonproductive thoughts in somatic symptoms and highlight that the strength of the relationship is similar across both genders but could be dependent upon age. The findings also shed light on the decreased well-being of girls, especially with elevated level of nonproductive thoughts.

Physical Health Complaints in Adolescents

Abstract. Background: Some of the physical health complaints adolescents have, such as headaches and stomachaches, cannot be explained on a somatic level. It is unclear which psychological factors can explain these complaints: stress and social support are often discussed, but emotions rarely are. Aims: This cross-sectional study aims to use social support, stress, the tendency toward negative emotions, and health behaviors to predict physical health complaints in adolescents. Method: The 2018 HBSC (Health Behavior in School-aged Children) data from the German state of Brandenburg was analyzed via structural equation and path modeling ( N = 3,068, age M = 13.05). Results: Results showed that the tendency toward negative emotions seems to be a better predictor for health complaints (β = .35) than stress (β = .17), and even better suited than social support (β = −.08) or health behavior (β = −.06 to β = .16). In the analysis of specific emotions (anger, sadness, and fear), correlations were low and between sadness and complaints they were highest (average β = .19). Limitations: The present cross-sectional study could not examine long-term outcomes. In addition, the results are limited to only a few physical complaints. Future long-term studies should examine multiple disease symptoms in adolescence. Conclusion: The investigated tendency toward negative emotions demonstrated promising results to better understand the relationship between psychological factors and physical health complaints. As negative emotions were particularly important in predicting physical health, prevention programs for adolescents should focus on dealing with negative emotions to improve their health.

Association between fluoride exposure and behavioural outcomes of school-age children: a pilot study in China

To assess the association between fluoride exposure and children's behavioural outcomes, we recruited 325 resident school-age children (7-13 years old) lived in Tongxu County of Henan Province in China. We measured urinary fluoride (UF) concentrations using the ion-selective electrode method. Children's behavioural outcomes were assessed by Conners' Parent Rating Scale-Revised, including conduct problems, learning problems, psychosomatic problems, impulsive-hyperactive, anxiety, and ADHD index. It turned out that each 1.0 mg/L increment in UF concentration corresponded with an elevation in the psychosomatic problem score of 4.01 (95% CI: 2.74, 5.28) and a 97% (OR = 1.97, 95% CI: 1.19, 3.27) increase in the prevalence of psychosomatic problems after adjusting for potential influencing factors. The sensitivity analysis results were consistent with those observed in our preliminary analysis. Our study suggests that fluoride exposure is positively related to the behavioural problem in school-age children, psychosomatic problem in particular.

Psychological Stresses in Children Trigger Cytokine- and Kynurenine Metabolite-Mediated Abdominal Pain and Proinflammatory Changes

Recurrent abdominal pain (RAP) is a common medically unexplained symptom among children worldwide. However, the biological mechanisms behind the development of functional and behavioral symptoms and changes in blood markers have not been well explored. This study aimed to assess changes in the concentrations of inflammatory markers, including cytokines and tryptophan catabolites, in the serum of children with RAP compared to those with subclinical infections. Children with RAP but without organic diseases were included, and those with asymptomatic intestinal parasitic infections were used as a subclinical infection cohort. Blood samples were collected and used to measure the cytokine profile using Multiplex Immunoassay and tryptophan catabolites using high performance liquid chromatography. Children with RAP showed significantly higher concentrations of serum tumor necrotic factor-α, p<0.05, but lower concentrations of IL-10, p<0.001, IL-6, p<0.001 and brain-derived neurotrophic factors (BDNF) p<0.01. In addition, a significant increase in the metabolite of the kynurenine pathway, 3-hydroxyanthranilic acid (3-HAA) p<0.01, a significant decrease in the concentrations of anthranilic acid (AA) p<0.001, together with an increased ratio of serum 3-HAA to AA (3-HAA/AA) p<0.001, was found in this cohort. These findings indicate the significant activation of the immune system and presence of inflammation in children with RAP than those with subclinical parasitic infections. Moreover, children with RAP tested with the Strengths and Difficulties Questionnaire (SDQ), displayed high psychological problems though these SDQ scores were not statistically associated with measured cytokines and kynurenine metabolites. We however could hypothesize that the pro-inflammatory state together with concomitant low concentrations of BDNF in those children with RAP could play a role in psychological stress and experiencing medically unexplained symptoms.

Psychosocial Factors Affecting Parental Report of Symptoms in Children: A Systematic Review

OBJECTIVE

Parents make important treatment decisions for their children based on symptoms they perceive their child to be experiencing. Multiple psychological factors are associated with subjective symptom perception, but factors affecting perception of symptoms in others have been explored less. We systematically reviewed the literature to identify parent and child psychological factors associated with parental report of physical symptoms in their child.

METHODS

We searched Embase, Ovid, PsycINFO, and Scopus for studies that investigated associations between psychological factors and parental report of symptoms in their child.

RESULTS

Thirty-six citations reporting on 34 studies that assessed the association between parent or child psychological factors and parental report of physical symptoms in the child were included in the review. Three main factors were identified as being associated with parental symptom report. First, there was evidence for an association between parental symptom report and affect, in particular parent and child anxiety. Second, child behavioral and conduct problems, and temperament-related challenges (problems with feeding and sleeping) were associated with parental symptom report. Third, parental expectations and beliefs that symptoms would occur were associated with parental symptom report, although few studies investigated these associations.

CONCLUSIONS

Parent and child affect, and parental expectations and beliefs may influence parents' cognition, causing them to pay more attention to their child, interpret their child's behavior as symptomatic, and recall symptoms in the child. Given the importance of parental perception of symptoms in driving decisions around care, additional research in this field is needed.

Medically unexplained symptoms in children: an experimental investigation of the impact of internet searching on parental responses

BACKGROUND

Medically unexplained symptoms (MUS) are symptoms for which no medical cause can be identified. For children and adolescents, symptoms can be maintained through parental responses.

AIMS

The present study investigated the impact that internet searching of symptoms has on parental responses to MUS.

METHOD

One hundred and twenty-seven adult participants read a vignette in which they were asked to imagine they were a parent of a young person with MUS and completed visual analogue scales (VAS) reporting their beliefs, emotions and behavioural intentions about the MUS. Participants were then randomly assigned to one of three conditions: searching reputable websites for further information about the symptoms (n = 47), free search of any websites for further information about the symptoms (n = 38) or a control condition (n = 42) during which participants spent 10 minutes doing their usual behaviour on the internet, for example checking email and social media. Participants then completed the VAS for a second time.

RESULTS

Searching reputable websites led to a significantly greater decrease in behaviour VAS scores compared with the free search condition [F (1,123) = 11.374, p < .001], indicating that participants were less likely to seek a second opinion and to advise the child to avoid usual activities.

CONCLUSIONS

This study demonstrated that internet searching reputable sites for information regarding physical symptoms can be positive and it may therefore be advisable for health professionals meeting children with MUS to provide the family with information links to reputable sources.

Medically unexplained symptoms in children and adolescents: Illness-related self-concept and parental symptom evaluations

BACKGROUND AND OBJECTIVES

According to cognitive-behavioral models, illness-related symptom evaluations and self-concepts play a pivotal role in the development and maintenance of medically unexplained somatic symptoms (MUS). However, illness-related cognitions related to MUS have rarely been studied in children/adolescents and their parents.

METHODS

Seventy-eight children and adolescents (M = 14.2 years; 59% female) performed two versions of the Implicit Association Test (IAT) to measure the implicit illness-related and the implicit anxiety-related self-concept. Illness-related evaluations of unspecific symptoms were assessed via the Health Norms Sorting Task (HNST), and MUS as well as characteristics of somatic symptom disorder (SSD) via questionnaires.

RESULTS

MUS were significantly positively associated with the explicit (r = 0.30, p < .01) and implicit illness-related self-concept (r = 0.24, p = .04), but not with the anxiety-related self-concept (r = 0.15, p = .18). The implicit illness-related self-concept explained incremental variance in MUS (ΔR² = 0.05, p = .04) beyond the explicit illness-related self-concept. Regarding health anxiety, parental illness-related symptom evaluations moderated the relationship between child-reported severity of MUS and health anxiety (B = 0.12, p < .01).

LIMITATIONS

Some measures have been adapted for childhood and adolescence, but validations on larger samples are still pending.

CONCLUSIONS

A disorder-specific self-concept of being ill, as well as parental symptom evaluations, seem to play an essential role in MUS and health anxiety in childhood and adolescence. Due to the importance of the top-down processes found here, the findings are in line with current predictive coding models of somatic symptom perception.

'Fixing my life': young people's everyday efforts towards recovery from persistent bodily complaints

Little is known about the perspectives of young people suffering from medically unexplained symptoms. This study aims to explore the experiences and strategies of young Norwegians related to incipient and persistent health complaints affecting everyday life functioning. The study draws on field notes, video material and interview transcripts from a multi-sited ethnographic study of healthcare services and select schools in a small Norwegian town between 2015 and 2016. A central theme is the emphasis upon social and existential constraints seemingly framed by a social imaginary of youth rather than a medical imaginary, and their active engagements to 'fix' their lives through what we identify as two main modalities of self-care. Navigating temporal and relational aspects of sociocultural configurations of youth in their social environments, they imagine and enact alternative qualifying positions better adapted to constraints, personal preferences and needs. Our findings may add to understandings of the needs and strategies of young sufferers of medically unexplained symptoms, relevant for health and social care encounters.

Long-term outcomes of functional neurological disorder in children

OBJECTIVES

To establish the incidence and long-term outcomes (up to 21 years) of children presenting to a University hospital paediatric neurology service with symptoms due to functional neurological disorder (FND) with particular reference to occurrence of FND or similar symptoms in adulthood.

METHODS

Retrospective chart review to determine characteristics of the original paediatric FND presentation plus record-linkage with providers of Child and Adolescent Mental Health Services. Chart review of adult medical records for documentation of functional symptoms in adulthood.

RESULTS

124 individuals (56% female) met entry criteria. The most common presentations were seizures (18%), sensory loss (18%) and motor symptoms (16%). Frequency gradually increased with age of onset with an incidence in paediatric neurological services of 6 per 100 000 children under 16. In up to 21 years' follow-up (median 8.3 years), 114/124 attained their 16th birthdays by the study census date and were thus eligible for inclusion in an analysis of symptom persistence/recurrence in adulthood. 26/114 (23%) showed evidence of FND in adulthood of sufficient significance to be recorded in medical records.

CONCLUSION

Paediatric FND is commoner than previous estimates. Even in this selected population of children reaching specialist paediatric neurology services, a high long-term remission rate is observed.

Somatic symptoms among prison inmates: contributions of emotion regulation, dispositional mindfulness, and duration of stay in prison

PURPOSE

The modern prison system is not only a necessity to keep the public safe but also a mode of punishment for crimes. The correctional role of prisons is hampered in situations of mental illness, given that mental illness in the prison or correctional setting is a serious security risk. Few studies have given attention to the modifiable factors that may influence the mental health status of prison inmates, especially in developing countries. The purpose of this paper is to investigate emotion regulation (ER), dispositional mindfulness and duration of stay as factors in somatic symptoms among prison inmates.

DESIGN/METHODOLOGY/APPROACH

Participants were 209 prison inmates drawn from a prison in Eastern Nigeria, who completed measures of ER (cognitive reappraisal and expressive suppression), mindfulness and somatization.

FINDINGS

Results of a hierarchical multiple regression indicated that cognitive reappraisal predicted somatic complaints but it was only among older prison inmates, while expressive suppression was not a significant predictor of somatic complaints. Dispositional mindfulness was a negative predictor of somatic complaints among younger and older prison inmates. Duration of stay in prison positively predicted somatic complaints among prison inmates in emerging adulthood only (younger inmates), but not among older inmates.

RESEARCH LIMITATIONS/IMPLICATIONS

Frequent use of cognitive reappraisal strategy of ER by prisoners may not always be productive in reducing somatic complaints, and the length of time in prison may influence somatic symptoms especially for younger prisoners. The possible benefits of incorporating mindfulness-based therapies in psychosocial interventions to reduce somatic complaints in correctional settings deserves further investigation.

ORIGINALITY/VALUE

To date, there is limited research on somatic complaints of prisoners in the developing societies, particularly the psychosocial factors that may contribute to mental health problems.

Careful expressions of social aspects: How local professionals in high school settings, municipal services, and general practice communicate care to youth presenting persistent bodily complaints

Persistent health complaints pose communicative dilemmas in care encounters, adversely affecting patient experiences and pathways. Little is known about the impact and role of professionals in encounters with young people with incipient, debilitating, and persistent symptoms. This study aims to explore communicative dilemmas and the role of language in care provided by local professionals in high school settings, municipal services, and general practice to young people presenting persistent bodily complaints. The study is based on in-depth individual interviews conducted from April to July 2016 with 12 professionals identified and selected during anthropological multi-sited fieldwork in a Norwegian community. We identify two modalities of what we have chosen to call 'careful expression', used as strategies across professions to overcome communicative dilemmas. Professionals reflexively and pragmatically negotiated with the powers of language to influence illness experience and to enact empowered young subjects. These insights may prove relevant for future studies of care encounters while also indicating a critical attitude to institutional logics that affect care responses.

Do negative childhood conditions increase the risk of somatic symptoms in adolescence? - a prospective cohort study

Background

In order to prevent health and social problems later in life, it is important to identify childhood conditions related to the development of somatic symptoms. This prospective study expands on previous research by investigating whether negative childhood conditions are related to somatization later in life, taking other risk factors into account.

This study aims to investigate whether somatic symptoms of the participants’ parents, poor family functioning, or negative life events during childhood result in somatic symptoms in early or late adolescence.

Methods

The study population includes participants from the West Jutland Cohort Study who responded to the survey on their somatic symptoms at age 15 (n = 2963) and/or age 18 (n = 2341). The study also includes additional questionnaire information about the participants’ poor family functioning, number of negative life events, and parental reports of somatic symptoms as well as register information about parental socioeconomic background. Generalized linear models for the binomial family were used and the results were presented as relative risks (RR) and risk differences (RD) with 95% confidence intervals (95%-CI).

Results

Experiencing poor family functioning at age 15 showed associations with somatic symptoms at age 15 (RR 1.75, 95%-CI, 1.43–2.14 and RD 18, 95%-CI, 11–25%) and 18 (RR 1.32, 95%-CI, 1.00–1.75 and RD 7, 95%-CI, 0.2–14%). The relative risks between poor family functioning and somatic symptoms were 2.5 for the boys at age 15 and 1.71 for the girls at age 18. Having experienced two or more negative life events up to the age of 15 was associated with reporting somatic symptoms at age 15 (RR 1.73, 95%-CI, 1.31–2.28 and RD 24, 95%-CI, 11–37%). No relative risks above 1.35 were found between parents reporting somatic symptoms and participants reporting somatic symptoms at ages 15 or 18.

Conclusions

An increased awareness of the association between a poor social climate in the family and somatic symptoms may help professionals in health and educational systems prevent the development of such symptoms among adolescents.

Epidemiology of spinal pain in children: a study within the Danish National Birth Cohort

This study aims to describe the prevalence of spinal pain among Danish children, explore the differential nature of spinal pain, and investigate socio-demographic factors predisposing spinal pain. A descriptive study of 46,726 11-14-year-olds participating in the Danish National Birth Cohort was conducted. Self-reported spinal pain (neck, middle back, and low back pain) was registered and classified according to severity. Socioeconomic data on children and their parents were identified in Statistics Denmark registers. Associations between socio-demographic factors and aspects of spinal pain were estimated using multinomial logistic regression models. To account for sample selection, inverse probability weighting (IPW) was applied. Almost 10% boys and 14% girls reported severe spinal pain, whereas around 30% of all children reported moderate pain. Effect estimates indicated the risk to increase with increasing age. Further, children without biological full siblings, not living with both of their parents, or children living in less-educated or lower-income families were more likely to experience spinal pain. The study conclusions were essentially unaffected by IPW.Conclusion: A considerable number of children suffer from spinal pain, and it is more common among children in more disadvantaged families. Etiology of spinal pain needs to be explored further with the aim of informing efficient and targeted prevention. What is Known: • Childhood spinal pain may cause marked discomfort and impairment in children's everyday life, and is suggested as important predictor of later-in-life spinal pain. • Methodological heterogeneity in previous studies and complexity of measuring pain make inferences at a broader level inadequate. What is New: • Prevalence of severe spinal pain in 11-14-year-olds was estimated to almost 10% for boys and 14% for girls, and children in more disadvantaged families were more likely to experience spinal pain. • The results seemed unaffected by sample selection.

Epistemological and methodological paradoxes: secondary care specialists and their challenges working with adolescents with medically unexplained symptoms

Background

Early adolescence is considered a critical period for the development of chronic and recurrent medically unexplained symptoms (MUS), and referrals and system-initiated patient trajectories often lead to an excess of examinations and hospitalizations in the cross-section between mental and somatic specialist care for this group of patients. Dimensions of the relationship and communication between clinician and patient are shown in primary care studies to be decisive for subsequent illness pathways, often creating adverse effects, but knowledge on clinical communication in specialist care is still scarce.

Methods

This study explores communicative challenges specific to clinical encounters between health professionals and adolescent patients in specialist care, as presented through interviews and focus group data with highly experienced specialists working in adolescent and child services at a Norwegian university hospital.

Results

The results are presented in a conceptual model describing the epistemological and methodological paradoxes inherent in the clinical uncertainty of MUS. Within these paradoxes, the professionals try to solve the dilemmas by being creative in their communication strategies; applying metaphors and other rhetorical devices to explain complex ideas; creating clinical prototypes as a way to explain symptoms and guide them in clinical action; relying on principles from patient-centered care involving empathy; and trying to balance expertise and humility.

Conclusion

The challenges in communication arise as a result of opposing discourses on biomedicine, family, health and adolescence that create dilemmas in everyday clinical work. By moving away from a positivist and biomedical framework towards an interpretive paradigm, where culturally derived and historically situated interpretations are used to understand the social life-world of the patient, one can create a more humane health service in accordance with ideals of patient-centered care.

Early-Life Somatic Complaints: Longitudinal Associations with Maternal and Child Psychopathology

OBJECTIVE

Somatic complaints, often associated with concurrent and future internalizing symptoms and disorders in adult samples, were examined longitudinally from preschool to school age in a sample of children at an increased familial risk for psychopathology. The behavioral correlates and sex differences of somatic complaints and the persistence of these complaints across early childhood were examined.

METHOD

A longitudinal sample of 185 mothers completed a laboratory visit when children were preschool aged and an online follow-up when children were school aged. Mothers were assessed for psychopathology, and mothers and secondary caregivers reported on children's somatic complaints, anxiety, and depression at both time points.

RESULTS

A high rate of child's somatic complaints was noted in this sample, with similar rates in males and females. Regression analyses revealed that somatic complaints at preschool predicted somatic complaints, anxiety, and depression at school age, and sex did not moderate these relationships. Overall, maternal psychopathology predicted somatic complaints, but findings were inconsistent across reporters, time points, and types of maternal psychopathology. Evidence for maternal reporting bias was mixed.

CONCLUSION

The association between preschool-age somatic complaints and school-age internalizing symptoms suggests the potential utility of early detection and treatment of somatic complaints, particularly for young children at an increased familial risk for developing internalizing disorders. Pediatric primary care is an ideal setting for these early intervention efforts.

‘Not a film about my slackness’: Making sense of medically unexplained illness in youth using collaborative visual methods

Persistent medically unexplained symptoms have debilitating consequences for adolescents, dramatically altering their social world and future aspirations. Few studies have focused on social and moral aspects of illness experience relevant to adolescents. In this study, the aim is to explore these aspects in depth by focusing on a single case and to address how young people attempt to create social accountability in a search for meaning when facing illness and adversity. The study is based on a view of meaning as dialogically constituted during the research process, which calls for the use of collaborative film methodology and life-mode interviewing. With a dialogic–performative approach to a narrative emplotment of medically unexplained symptoms, we present Peter as intentional and purposive, and as a person who in a reflective process of meaning making claimed his own voice and developed his own strategies of coping with his illness. The analysis brings forward a narrative of suffering, hope and intentionality that is configured by the immediate limited possibilities of agency due to Peter’s medical condition. It is, however, configured to an even greater degree by aspirations, that is, to become an accountable person through social experiences and to meet sociocultural and moral expectations of being an adolescent. The study provides insight into relational and existential aspects of meaning making in dealing with contested illness in youth and points to the potential of visual and other experience-near methods for supporting adolescents in their coping attempts and in overcoming communication barriers in everyday life and clinical encounters.

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.

Somatic symptom disorder was common in children and adolescents attending an emergency department complaining of pain

AIM

The aim of this study was to quantify the prevalence of somatic pain in a paediatric emergency department (ED).

METHODS

We conducted a prospective observational study using patients admitted to the ED of an Italian children's hospital between December 2014 and February 2015. We enrolled children aged 7-17 who turned up at the ED complaining of pain. Patients and parents were asked to fill in a questionnaire to allow the analysis of the patients' medical history and provide contact details for follow-up. We divided the enrolled patients into four groups: post-traumatic pain, organic pain, functional pain and somatic pain. The questionnaire was used to define pain characteristics and to generate an impairment score.

RESULTS

Of the 713 patients who met inclusion criteria, 306 (42.9%) were enrolled in the study. Of these, 135 (44.0%) suffered from post-traumatic pain, 104 (34.0%) from organic pain, 41 (13.4%) from functional pain and 26 (8.6%) from somatic pain. Somatic pain patients had endured pain longer, had missed more school days and had suffered severe functional impairment.

CONCLUSION

This study highlighted that somatic pain was a significant contributor to paediatric emergency room visits and should be suspected and diagnosed in children reporting pain.

Trends in the Diagnosis of Vitamin D Deficiency

BACKGROUND

Vitamin D has attracted considerable interest in recent years, and health care providers have reported large increases in vitamin D test requests. However, rates of diagnosis of vitamin D deficiency in clinical practice have not been investigated. We examined trends in diagnosis of vitamin D deficiency in children in England over time, and by sociodemographic characteristics.

METHODS

Cohort study using primary care records of 711 788 children aged 0 to 17 years, from the Health Improvement Network database. Incidence rates for diagnosis of vitamin D deficiency were calculated per year between 2000 and 2014. Rate ratios exploring differences by age, sex, ethnicity, and social deprivation were estimated using multivariable Poisson regression.

RESULTS

The crude rate of vitamin D deficiency diagnosis increased from 3.14 per 100 000 person-years in 2000 (95% confidence interval [CI], 1.31-7.54) to 261 per 100 000 person-years in 2014 (95% CI, 241-281). After accounting for changes in demographic characteristics, a 15-fold (95% CI, 10-21) increase in diagnosis was seen between 2008 and 2014. Older age (≥10 years), nonwhite ethnicity, and social deprivation were independently associated with higher rates of diagnosis. In children aged <5 years, diagnosis rates were higher in boys than girls, whereas in children aged ≥10 they were higher in girls.

CONCLUSIONS

There has been a marked increase in diagnosis of vitamin D deficiency in children over the past decade. Future research should explore the drivers for this change in diagnostic behavior and the reasons prompting investigation of vitamin D status in clinical practice.

Family functioning as a protective factor in treating adolescents with complex medico-psychosocial presentations

PURPOSE

Studies of adolescents with somatic symptoms with no identified organic cause make a clear connection between the health and wellbeing of the adolescent and the functioning of the family. There has been little systematic examination of the role of family functioning in treatment. We aim to determine whether there was an association between family functioning and treatment outcome in this 12 month prospective study.

METHODS

Fifty adolescents aged between 12 and 17 years (M=14.4, SD=1.32) and their parents were recruited. All adolescents presented with one or more physical symptoms as their primary complaint. Adolescent functioning and family relationships were measured at recruitment, 4 months into treatment and 12 months later. Generalised estimating equations (GEE) analyses were conducted to examine the relationships between the variables of interest.

RESULTS

Results suggested significant improvements in adolescent outcomes between baseline and 4 months (all p<0.01), which were sustained to 12 months (all p<0.01). Adolescents from healthier families at initial presentation had significantly improved psychosocial functioning over the course of the study (all p<0.001).

CONCLUSION

Our findings highlight the importance of taking a family approach to the treatment of adolescents with medically unexplained symptoms.

Common Etiological Sources of Anxiety, Depression, and Somatic Complaints in Adolescents: A Multiple Rater twin Study

Somatic complaints in children and adolescents may be considered part of a broader spectrum of internalizing disorders that include anxiety and depression. Previous research on the topic has focused mainly on the relationship between anxiety and depression without investigating how common somatic symptoms relate to an underlying factor and its etiology. Based on the classical twin design with monozygotic and dizygotic twins reared together, our study aimed to explore the extent to which the covariation between three phenotypes in adolescent girls and boys can be represented by a latent internalizing factor, with a focus on both common and specific etiological sources. A population-based sample of twins aged 12-18 years and their mothers and fathers (N = 1394 families) responded to questionnaire items measuring the three phenotypes. Informants' ratings were collapsed using full information maximum likelihood estimated factor scores. Multivariate genetic analyses were conducted to examine the etiological structure of concurrent symptoms. The best fitting model was an ACE common pathway model without sex limitation and with one substantially heritable (44%) latent factor shared by the phenotypes. Concurrent symptoms also resulted from shared (25%) and non-shared (31%) environments. The factor loaded most on depression symptoms and least on somatic complaints. Trait-specific influences explained 44% of depression variance, 59% of anxiety variance, and 65% of somatic variance. Our results suggest the presence of a general internalizing factor along which somatic complaints and mental distress can be modeled. However, specific influences make the symptom types distinguishable.

Comparing group-based acceptance and commitment therapy (ACT) with enhanced usual care for adolescents with functional somatic syndromes: a study protocol for a randomised trial

INTRODUCTION

Functional somatic syndromes (FSS) are common in adolescents, characterised by severe disability and reduced quality of life. Behavioural treatments such as acceptance and commitment therapy (ACT) has shown promising results in children and adolescents with FSS, but has focused on specific syndromes such as functional pain. The current study will compare the efficacy of group-based ACT with that of enhanced usual care (EUC) in adolescents with a range of FSS operationalised by the unifying construct of multiorgan bodily distress syndrome (BDS).

METHODS AND ANALYSIS

A total of 120 adolescents aged 15-19 and diagnosed with multiorgan BDS, of at least 12 months duration, will be assessed and randomised to either: (1) EUC: a manualised consultation with a child and adolescent psychiatrist and individualised treatment plan or (2) manualised ACT-based group therapy plus EUC. The ACT programme consists of 9 modules (ie, 27 hours) and 1 follow-up meeting (3 hours). The primary outcome is physical health, assessed by an Short Form Health Survey (SF-36) aggregate score 12 months after randomisation. Secondary outcomes include self-reported symptom severity, symptom interference, depression and anxiety, illness worry, perceived stress and global improvement; as well as objective physical activity and bodily stress response measured by heart rate variability, hair cortisol and inflammatory biomarkers. Process measures are illness perception, illness-related behaviour and psychological flexibility.

ETHICS AND DISSEMINATION

The study is conducted in accordance with Helsinki Declaration II. Approval has been obtained from the Science Ethics Committee of the Central Denmark Region and the Danish Data Protection. The results will be sought to be published according to the CONSORT statement in peer-reviewed journals.

DISCUSSION

This is one of the first larger randomised clinical trials evaluating the effect of a group-based intervention for adolescents with a range of severe FSS.

TRIAL REGISTRATION NUMBER

NCT02346071; Pre-results.

[Internal consistency and criterion validity and reliability of the Mexican Version of the Child Behavior Checklist 1.5-5 (CBCL/1.5-5)]

OBJECTIVE

To investigate the validity and internal consistency of the Mexican version of the CBCL/1.5 -5 that assesses the most common psychopathology in pre-school children in clinical and epidemiological settings.

PATIENTS AND METHOD

A total of 438 parents from two groups, clinical-psychiatric (N= 62) and community (N= 376) completed the CBCL/1.5-5/Mexican version.

RESULTS

The internal consistency was high for total problems α=0.95, and internalized α=0.89 and externalized α=0.91 subscales. The test re-test (one week) using the intraclass correlation coefficient (ICC) was ≥ 0.95 for the internalized, externalized, and total problems subscales. The ROC curve for the criterion status of clinically-referred vs. non-referred using the total problems scale ≥ 24 resulted in an AUC (area under curve) of 0.77, a specificity 0.73, and a sensitivity of 0.70.

CONCLUSIONS

The CBCL/1.5 -5/Mexican version is a reliable and valid tool.

Clinical features of functional somatic symptoms in children and referral patterns to child and adolescent mental health services

AIM

Functional somatic symptoms (FSS) are common in paediatric patients who are referred to Child and Adolescent Mental Health Service (CAMHS), but little is known about current referral practices. The aim of this study was to systematically investigate clinical features of paediatric inpatients with FSS referred to CAMHS and to describe why paediatricians referred them.

METHODS

The study population comprised 60 children with FSS admitted to a large Danish paediatric department during 2012. We compared medical record data on the clinical characteristics and paediatric management of 16 children who had been referred and 44 children who had not.

RESULTS

Most paediatric records lacked information on psychosocial factors and symptoms. Referred children were significantly more multisymptomatic of FSS (p < 0.01) than the controls, had longer symptom duration, underwent more clinical investigations, had longer paediatric admissions of at least two weeks and received more treatment elements before referral. The most frequently stated referral reason was inadequate treatment response.

CONCLUSION

Paediatric inpatients with more severe FSS were more likely to be referred to CAMHS, but referral reasons were generally vague and psychosocial information was frequently missing. Clinical guidelines are needed to improve and systematise mental health referrals for children with FSS.
