Attention-deficit/hyperactivity disorder and physical multimorbidity: A population-based study

Somatic comorbidities and health related uncertainty among Swedish adolescents with ADHD

Introduction

Attention-deficit/hyperactivity disorder (ADHD) frequently exists alongside psychiatric comorbidities. The coexistence of somatic diseases and ADHD constitutes a growing field of research.

Method

This study aimed to examine the prevalence of common somatic diseases in adolescents with ADHD and compare them with those in adolescents without any psychiatric diagnoses. A cross-sectional study was conducted among a convenient sample of Swedish upper secondary school students aged 15 to 19 years. Data were collected using an electronic version of the "Mental and Somatic Health without borders" survey. In 2020, 1608 adolescents completed the survey and provided self-reports of their psychiatric and somatic diagnoses.

Results

Among the sample of Swedish adolescents, 5.5% reported having ADHD diagnoses. These adolescents reported more somatic comorbidities than those without any psychiatric diagnosis (comparison group). The most common somatic comorbidities among those with ADHD were allergies (43.4%), asthma (24.7%), and skin diseases (16.7%), which prevalences were significantly higher than those reported by adolescents in the comparison group. However the effect sizes of these differences were negligible (allergies: p=0.002, Cramer's V=0.08; asthma: p=0.041, Cramer's V=0.06; skin diseases: p=0.007, Cramer's V=0.08), raising questions about the practical implications of these findings. Allergies were significantly more common in both genders with ADHD (p=0.038, Cramer's V=0.08 in women and p=0.038, Cramer's V=0.09 in men). Additionally, men with ADHD showed a significant association with skin diseases (p=0.007, Cramer's V=0.12) while women with ADHD were significantly more likely to have migraine (p=0.038, Cramer's V=0.08). Notably, adolescents with ADHD reported significantly higher rates of uncertainty regarding the existence of diabetes, rheumatoid diseases, asthma (with negligible effect sizes), and thyroid diseases (with a small effect size) than those without any psychiatric diagnoses, suggesting heightened health related anxiety within this group.

Conclusions

Adolescents with ADHD reported more somatic comorbidities and greater uncertainty about the potential presence of additional somatic conditions compared to adolescents without psychiatric diagnoses. These findings highlight the importance of addressing both health literacy and access to healthcare. By focusing on this group, we cannot only improve their ability to understand and navigate the healthcare system but also strengthen their confidence in managing their own health.

Psychosocial interventions for improving the physical health of young people and adults with attention deficit hyperactivity disorder: a scoping review

BACKGROUND

Young people and adults with ADHD are at risk of a range of physical health problems. There is limited guidance on how to approach health problems in ADHD, and especially around 16-25 year olds who will be transitioning from paediatric to adult care. The aim of this scoping review was to identify psychosocial interventions that target physical health in young people and adults with ADHD.

METHODS

We constructed searches in MEDLINE, PsycInfo, EMBASE of adolescents, young people and adults. Inclusion criteria were; studies of psychosocial interventions examining a component of physical health, applicable to people aged 16-25, with clinical or research diagnoses of ADHD. Data were extracted using a data extraction tool and tabulated, including study intervention framing/aims, population, intervention, and relevant outcomes (including specific statistics where relevant).

RESULTS

Our search identified 22 unique papers covering, psychosocial interventions targeting at least one of sleep (n=7), smoking (n=3), substance/alcohol use (n=4), physical health/exercise (n=6) and general health (n=3). Studies examined psychotherapy/behaviour interventions (n=12), psychoeducation (n=4), digital (n=2) and social interventions (n=4). There was significant heterogeneity in intervention framing, outcome measures and population.

CONCLUSION

Further work on the impact of targeted physical health interventions, with explicit reference to a conceptual framework of poor health in ADHD is required. Furthermore, future work standardising reporting of physical health outcomes in ADHD is crucial for the development of an evidence base in this field.

Wider health needs in attention deficit hyperactivity disorder from lived and professional experience: a qualitative framework analysis

OBJECTIVES

This study aimed to explore the perspectives of people with attention deficit hyperactivity disorder (ADHD), their supporters and primary care professionals (PCPs), on the wider physical and mental health needs of people with ADHD and the support currently available.

DESIGN

Qualitative semi-structured interviews, analysed using reflexive thematic analysis.

SETTING

Five general practice surgeries across England.

PARTICIPANTS

Participants with lived experience (people with ADHD and their supporters (n=11)) and PCPs (n=9) (eg, general practitioners and practice managers), recruited via clinical academic networks and previous work packages of this study.

RESULTS

We generated three major themes in relation to ADHD, using reflexive thematic analysis: understanding health, barriers to health and addressing health. Within these, participants reflected on mental and physical health challenges, as well as wider social difficulties and variability in support offered/accessed.

CONCLUSIONS

This study highlights that health problems in ADHD are complex and rooted both in individual factors (eg, mental health) and social factors (eg, support). This study also highlights the differences in expectations and fulfilment of healthcare.

Patient, supporter and primary healthcare professional perspectives on health risks in over 16s with attention deficit hyperactivity disorder (ADHD) in England: a national survey study

BACKGROUND

Current research suggests that people with attention deficit hyperactivity disorder (ADHD) are at higher risk of physical and mental health disorders. This study aimed to explore these health risks in ADHD from the perspectives of multiple stakeholders.

METHODS

This study forms part of the 'Managing young people with ADHD in Primary care (MAP) study'. A survey developed by the study team was distributed to over 16 year olds with ADHD, their supporters, primary healthcare professionals and health commissioners across England, via social media and through patient/clinical networks (September-October 2022). This survey contained two questions on health risks. Question one asked about views on health risks in ADHD (free text). Question two asked about advice given (options list and free text). Descriptive statistics summarised responses to questions one and two, and qualitative analysis (reflexive thematic analysis) was used to explore free text responses from question one.

RESULTS

782 participants responded to the MAP survey. Of these, 206 healthcare professionals, 157 people with ADHD and 88 supporters answered question one. The most mentioned perceived risks were substance misuse, sleep disorders, weight management and smoking. More people with ADHD reported disordered eating as a health risk (n = 32) than healthcare professionals (n = 5). Generated themes included perceived health risks, impact of living with ADHD, lack of adequate healthcare, and need for ADHD awareness. In respect to advice given (question two), based on responses from 258 professionals, 162 people with ADHD and 100 supporters, the most common advice discussed in consultation was mental health (n = 149, n = 50 and n = 17 respectively). High numbers of respondents reported not giving/receiving advice on wider health (n = 38, n = 88 and n = 61 respectively).

CONCLUSIONS

Findings demonstrate that respondents perceived a range of physical and mental health risks posed by ADHD. These related to difficulties with activities of daily living, as well as healthcare interactions and the impact of core features of ADHD (e.g. impulsivity, emotional dysregulation). These risks are not currently explicitly addressed in United Kingdom national guidance on ADHD. More work is needed to examine and address the broader health outcomes of people with ADHD.

Prevalence of adult attention deficit hyperactivity disorder in India: a systematic review and a cross-sectional study among young adults in Delhi-NCR

PURPOSE

The epidemiology of adult attention deficit hyperactivity disorder (ADHD) is not well explored in India. The present study aims to systematically review the literature on the prevalence of adult ADHD in India and also estimate the prevalence and sociodemographic correlates of adult ADHD among the young adults in Delhi-NCR.

METHODS

For the systematic review, 494 articles were identified of which 10 were included in the review. Simultaneously, a cross-sectional study was conducted involving 1665 adults (18-25 years; mean age 19.92) of both sexes (69.1% females) from different colleges in Delhi-NCR, India. Data was collected using structured interviews and standardized diagnostic tool ASRS V1.1 was used for screening of ADHD.

RESULT

The systematic review revealed a high prevalence of adult ADHD ranging from 5.48 to 25.7% among general and specific populations of India. Further, in the cross-sectional study, 14% of participants were screened positive for ADHD. While factors like South Indian origin and higher maternal education were associated with an increased risk of adult ADHD, low socioeconomic status was found to be protective.

CONCLUSION

Considering the high prevalence of adult ADHD in India, there is an urgent need to increase awareness regarding adult ADHD and identify vulnerable populations to facilitate informed interventions.

Prevalence of somatic diseases in adults with attention deficit hyperactivity disorder in Japan is highest in people aged ≥40 years with mental disorders: a cross-sectional study of a Japanese health insurance claims database

Introduction

Studies have reported an association between attention deficit hyperactivity disorder (ADHD) and somatic diseases; however, the correlation of mental disorders with the association between ADHD and somatic diseases remains uninvestigated. This study investigated and compared the prevalence of somatic diseases among adults with/without ADHD, stratified by the presence or absence of mental disorders.

Methods

This cross-sectional study (October 2020-September 2021), using data (June 2013-September 2021) from a Japanese health insurance claims database, included adult participants with a medical record of and receiving medication for ADHD (ADHD group); the control group (matched 1:5 by age/sex) comprised participants without ADHD. The prevalence and odds ratio (OR; ADHD versus control) of type 2 diabetes mellitus (T2DM), diabetes complications, hypertension, cardiovascular disease (CVD), dyslipidemia, gout and hyperuricemia, chronic obstructive pulmonary disease (COPD), non-alcoholic fatty liver disease/non-alcoholic steatohepatitis (NAFLD/NASH), and atopic dermatitis were investigated. Pooled ORs for stratified analysis were calculated using the Mantel-Haenszel method.

Results

In the matched analysis sets, the ORs for all somatic diseases were significantly higher for the ADHD group (n=15,028) versus the control group (n=74,796). On stratified analysis, the Mantel-Haenszel ORs were significant for NAFLD/NASH (1.53; 95% confidence interval [CI]: 1.34, 1.73), diabetes complications (1.39; 95% CI: 1.09, 1.77), and gout and hyperuricemia (1.34; 95% CI: 1.19, 1.51). Furthermore, the stratum-specific ORs for T2DM, hypertension, and dyslipidemia were >1 and <1 in the presence and absence of mental disorders, respectively. The prevalence of all somatic diseases except atopic dermatitis increased with age. For participants aged ≥40 years, the Mantel-Haenszel ORs were significant for all somatic diseases except CVD, COPD, and atopic dermatitis.

Conclusions

The prevalence of several somatic diseases, including chronic disorders, was high among adults with ADHD, particularly in those aged ≥40 years and those with mental disorders.

Toward an Increased Attention on ADHD Symptoms and Traits in Young Adults: Prevalence Data From Screening Tools in a Psychiatric Outpatient Clinic

OBJECTIVE

to analyze the prevalence of ADHD symptoms and traits in a heterogeneous clinical psychiatric sample of young adults (aged 18-24 years old), who referred to a specialized outpatient clinic for various psychiatric and psychological disturbances.

METHOD

259 participants completed three validated self-report screening questionnaires for ADHD: the Wender Utah Rating Scale (WURS), the Adult Attention-Deficit/Hyperactivity Disorder Self-Report Screening Scale for DSM-5 (ASRS-5), and the Conners' adult ADHD rating scale (CAARS).

RESULTS

12.4% of our sample scored above the cut-off at both the WURS and the ASRS-5 and was considered at risk of ADHD.

CONCLUSION

the prevalence rate in our sample is higher than the one found in the adult general population (6.76%), and in the lower range of the one found in the adult clinical population (6.9%-38.8%). The potential role of sociodemographic (age, sex, gender identity, and employment) and comorbidity factors is discussed.

Is quality of life related to high autistic traits, high ADHD traits and their Interaction? Evidence from a Young-Adult Community-Based twin sample

This study explored whether high autistic traits, high attention deficit hyperactivity disorder (ADHD) traits and their interaction were associated with quality of life (QoL) in a sample of 556 of young-adult twins (Mean age 22 years 5 months, 52% Female). Four participant groups were created: high autistic traits, high ADHD traits, high autistic/ADHD traits, and low ADHD/autistic traits. High autistic traits were associated with lower QoL across domains (physical, psychological, social, and environmental). High ADHD traits associated with lower physical, psychological, and environmental QoL. The interaction of autistic and ADHD traits was not significant in any domain. While mental health difficulties were associated with lower QoL, after accounting for mental health, most relationships between autistic traits, ADHD traits and QoL remained.

The diagnosis and treatment of attention-deficit hyperactivity disorder (ADHD) in older adults

INTRODUCTION

There is a striking knowledge gap on ADHD in older adults, and the diagnosis as well as treatment for ADHD in this age group.

AREAS COVERED

The authors first review the literature on the prevalence, functional impairment, and health comorbidities of ADHD across the lifespan. Next, they address the diagnostic criteria for ADHD in adults according to the DSM/ICD, available screening/diagnostic tools, differential diagnosis, and the validity of diagnostic criteria for ADHD in older adults. Finally, the authors focus on empirical evidence on the prevalence rates, medication response, and safety of pharmacological treatment of ADHD in older adults, and national and international clinical guidelines on the treatment of ADHD in this age group.

EXPERT OPINION

It is expected that future editions of the DSM and ICD will provide specifiers to the standard ADHD criteria, to better inform the diagnosis of ADHD in older adults. It is also expected that the increasing number of epidemiological studies will provide rigorous estimates on the prevalence, incidence, and burden of ADHD in older adults. One may expect an increasing number of RCTs assessing the efficacy/effectiveness and tolerability/safety of pharmacological as well as non-pharmacological interventions which will inform future guidelines on ADHD in older adults.

Associations between Chronic Pain and Attention-Deficit Hyperactivity Disorder (ADHD) in Youth: A Scoping Review

Background: Chronic pain and ADHD are common conditions among youth that negatively impact functioning. This review fills a critical gap by summarizing current research on chronic pain and ADHD comorbidity, and it proposes a conceptual model of shared associations and underlying mechanisms. Objective: The aims of the current study were to: (1) review the extant literature and present estimates of the prevalence of comorbid non-headache chronic pain and ADHD in youth and (2) describe potential shared mechanisms for ADHD and chronic non-headache pain in youth. We also outline future directions to inform future research and interventions directed to youth with comorbid pain and ADHD. Design: A scoping review of the literature was performed in MEDLINE, PsycInfo, and Cochrane Database of Systematic Reviews using a wide range of search terms related to pain, Attention Deficit-Hyperactivity Disorder, childhood, adolescence, and young adulthood. Results: Eleven published studies were included in the review. These studies examined the prevalence of chronic pain among youth with ADHD, the prevalence of ADHD in chronic pain samples, and the association between chronic pain and ADHD among youth. Findings revealed results from studies indicating a higher prevalence of ADHD among youth with chronic pain and a higher prevalence of chronic pain in samples of youth with ADHD. Conclusions: Findings from this scoping review suggest an association between chronic pain and ADHD among youth. Little research was found to examine the etiology of this association. Future studies should examine underlying mechanisms of comorbid chronic pain and ADHD.

Association between Polygenic Risk Scores for ADHD and Asthma: A Birth Cohort Investigation

OBJECTIVE

Shared genetic mechanisms have been hypothesized to explain the comorbidity between ADHD and asthma. To evaluate their genetic overlap, we relied on data from the 1982 Pelotas birth cohort to test the association between polygenic risk scores (PRSs) for ADHD (ADHD-PRSs) and asthma, and PRSs for asthma (asthma-PRSs) and ADHD.

METHOD

We analyzed data collected at birth, 2, 22, and 30 years from 3,574 individuals.

RESULTS

Subjects with ADHD had increased risk of having asthma (OR 1.92, 95% CI 1.01-3.66). The association was stronger for females. Our results showed no evidence of association between ADHD-PRSs and asthma or asthma-PRSs and ADHD. However, an exploratory analysis suggested that adult ADHD might be genetically associated with asthma.

CONCLUSION

Our results do not support a shared genetic background between both conditions. Findings should be viewed in light of important limitations, particularly the sample size and the self-reported asthma diagnosis. Studies in larger datasets are required to better explore the genetic overlap between adult ADHD and asthma.

Attention-deficit/hyperactivity disorder symptoms, perceived stress, and suicidal ideation during the COVID-19 pandemic

OBJECTIVE

Attention-deficit/hyperactivity disorder (ADHD) symptoms have been linked to suicidal behavior. However, little is known about the mechanisms involved in this association. This study examined ADHD symptoms and suicidal ideation during the COVID-19 pandemic and the role of self-perceived stress in this association.

METHOD

Data were analyzed from an online sample of 1,452 Japanese individuals aged 18 to 89 obtained in February 2021. Information was collected on past-year suicidal ideation. ADHD symptoms were assessed with the Adult ADHD Self-Report Scale (ASRS) Screener while stress was measured with the Perceived Stress Scale (PSS-14). Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ-9), while the Generalized Anxiety Disorder scale (GAD-7) was used to assess anxiety symptoms. Logistic regression was used to examine associations.

RESULTS

Fifty-one (3.5%) individuals had ADHD symptoms, while more than one in ten (11.7%) of the respondents reported past-year suicidal ideation. In an analysis adjusted for sociodemographic factors, ADHD symptoms were associated with eight times higher odds for past-year suicidal ideation. However, adjusting the analysis for mental health variables (anxiety and depressive symptoms) attenuated the association which became non-significant (odds ratio [OR]: 1.96, 95% confidence interval [CI]: 0.92-4.18). In contrast, in an analysis adjusted for mental health, individuals with ADHD symptoms and stress had significantly higher odds for suicidal ideation (OR: 3.72, 95%CI: 1.43-9.67) whereas, ADHD symptoms without stress were not linked to suicidal ideation (OR: 1.25, 95%CI: 0.38-4.18).

CONCLUSIONS

Self-perceived stress is important in the association between ADHD symptoms and suicidal ideation among individuals in Japan during the COVID-19 pandemic. Detecting and managing stress and its effects in individuals with ADHD/ADHD symptoms should be a therapeutic focus for improving health-related outcomes in this population both during the COVID-19 pandemic and beyond.

Attention-deficit/hyperactivity disorder has a state-dependent association with asthma: The role of systemic inflammation in a population-based birth cohort followed from childhood to adulthood

There is a high comorbidity between attention-deficit/hyperactivity disorder (ADHD) and asthma, and inflammation has been proposed as a potential pathophysiological mechanism behind this association. Most studies conducted so far have used a cross-sectional design, and none has evaluated the prevalence of asthma symptoms in patients with ADHD followed from childhood to adulthood. We relied on data from the 1993 Pelotas birth cohort to evaluate the association between ADHD and asthma in patients with distinct patterns of incidence, persistence and remission, and to explore the potential role of inflammatory markers in the comorbidity. We analyzed data from 3281 individuals from the 1993 Pelotas birth cohort collected at birth (1993), 11 years (2004), 18 years (2011), and 22 years (2015). Subjects were first classified according to their ADHD and asthma status as early-onset (EO) persistent (positive screening for ADHD at 11 years and diagnosis of ADHD according to DSM-5, except criterion E, at either 18 or 22 years), EO-remittent (positive screening for ADHD at 11 years only), late-onset (diagnosis of ADHD according to DSM-5, except criterion E, at 18 or 22 years only), or healthy subjects (negative for both conditions in all evaluation). After controlling for confounders, significant associations were observed between EO-remittent ADHD and EO-remittent asthma (OR 1.68, 95% CI 1.11-2.55), EO-persistent ADHD and EO-persistent asthma (OR 4.33, 95% CI 1.65-11.34), and between late-onset ADHD and late-onset asthma (OR 1.86, 95% CI 1.28-2.70), suggesting a state-dependent association. Serum interleukin-6 (IL-6) and C-reactive protein (CRP) were measured at the 18- and 22-year evaluations and compared between subjects positive for ADHD, asthma, and subjects with both or none conditions, regardless of the previously defined trajectories. Subjects with comorbid ADHD and asthma presented higher levels of IL-6 at the 18- and 22-year evaluations when compared to subjects negative for both conditions. Our results demonstrate a state-dependent association between ADHD and asthma despite underlying trajectories. Higher levels of serum IL-6 in patients with both conditions suggest that a pro-inflammatory environment might have a role in the pathophysiological mechanisms underlying the comorbidity.

Childhood neurodevelopmental markers and risk of premature mortality: Follow-up to age 60-65 years in the Aberdeen Children of the 1950s study

Background

Individual neurodevelopmental disorders are associated with premature mortality. Little is known about the association between multiple neurodevelopmental markers and premature mortality at a population level. The ESSENCE (Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations) approach considers multiple neurodevelopmental parameters, assessing several markers in parallel that cluster, rather than considering individual diagnostic categories in isolation.

Objectives

To determine whether childhood neurodevelopmental markers, including reduced intellectual functioning, are associated with all-cause premature mortality.

Methods and procedures

In a general population cohort study (n = 12,150) with longitudinal follow up from childhood to middle age, Cox proportional hazard models were used to study the associations between childhood neurodevelopmental markers (Rutter B scale and IQ) and premature all-cause mortality.

Outcomes and results

The cognitive measures and 21 of the 26 Rutter B items were significantly associated with premature mortality in bivariate analyses with hazard ratios from 1.24 (95% CI 1.05–1.47) to 2.25 (95% CI 1.78–2.90). In the final adjusted model, neurodevelopmental markers suggestive of several domains including hyperactivity, conduct problems and intellectual impairment were positively associated with premature mortality and improved prediction of premature mortality.

Conclusions

A wide range of neurodevelopmental markers, including childhood IQ, were found to predict premature mortality in a large general population cohort with longitudinal follow up to 60–65 years of age.

Implications

These findings highlight the importance of a holistic assessment of children with neurodevelopmental markers that addresses a range of neurodevelopmental conditions. Our findings could open the door to a shift in child public mental health focus, where multiple and/or cumulative markers of neurodevelopmental conditions alert clinicians to the need for early intervention. This could lead to a reduction in the risk of broad health outcomes at a population level.

Psychiatric and Nonpsychiatric Comorbidities Among Children With ADHD: An Exploratory Analysis of Nationwide Claims Data in Germany

Objective: This study examined the full spectrum of comorbid disorders in all statutory-health-insured children aged 5 to 14 years with ADHD in 2017 by using nationwide claims data in Germany. Method: Children with ADHD (n = 258,662) were compared for the presence of 864 comorbid diseases with a control group matched by gender, age, and region of residence (n = 2,327,958). Results: Among others, metabolic disorders (odds ratio [OR] = 9.18; 95% confidence interval [CI] = [8.43, 9.99]), viral pneumonia (OR = 4.95; 95% CI = [2.37, 10.33]), disorders of white blood cells (OR = 4.55; 95% CI = [3.83, 5.40]), kidney failure (OR = 3.33; 95% CI = [2.65, 4.18]), hypertension (OR = 3.26; 95% CI = [3.00, 3.55]), obesity (OR = 2.85; 95% CI = [2.80, 2.91]), type 2 diabetes (OR = 2.61; 95% CI = [2.11, 3.23]), migraine (OR = 2.49; 95% CI = [2.37, 2.61]), asthma (OR = 2.19; 95% CI = [2.16, 2.22]), atopic dermatitis (OR = 2.10; 95% CI = [2.16, 2.23]), juvenile arthritis (OR = 1.56; 95% CI = [1.39, 1.76]), glaucoma (OR = 1.51; 95% CI = [1.30, 1.75]), and type 1 diabetes (OR = 1.30; 95% CI = [1.20, 1.40]) were more likely to be diagnosed in ADHD children. Conclusion: Along with psychiatric diseases, various somatic diseases were more common in ADHD children. The results have direct implications for patient care, including fine-grained diagnostics and personalized therapy.

The Importance of Belonging to a Context: A Nurse-Led Lifestyle Intervention for Adult Persons with ADHD

Living with attention deficit hyperactivity disorder (ADHD) and mental illness involves an increased risk of lifestyle-related diseases. Although there are several ways to provide support to adult persons with ADHD, there is a lack of non-medical strategies for this purpose. This study explore how adult persons with ADHD with mental illness experienced taking part in a nurse-led lifestyle intervention. Fifteen participants participated in a 52-week lifestyle intervention. The analysis revealed two main categories; Building trusting relationships and Health together. This nurse-led lifestyle intervention could be an alternative or complement to current approaches to promoting health in adults with ADHD.

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

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

Occupational experiences of college students with ADHD: A qualitative study

BACKGROUND

College students with attention deficit hyperactivity disorder (ADHD) face difficulties with occupational performance in many functional domains. Despite the broad literature on academic and psychosocial functions, there is a gap in knowledge regarding how these students experience participation in their various daily functions.

OBJECTIVE

Gaining a deeper understanding of the occupational experiences of college students with ADHD and exploring factors that facilitate or impede their occupational performance.

METHOD

Twenty college students with ADHD were interviewed using the Occupational Performance History Interview (OPHI-II). Qualitative content analysis was employed.

RESULTS

Six themes were found in relation to varied occupational domains: (1) Eating and meal preparation: Too little or too much; (2) Sleep: Not enough to 'recharge batteries'; (3) Medication management: Intense ambivalence; (4) Studying: Too hard, too effortful (5) Work: Need it and love it; and (6) Leisure: Desired yet absent. Each theme contained categories related to factors that influenced performance. Impeding factors included occupational demands, ADHD biological attributes, and personal beliefs. Facilitating factors included self-awareness, executive strategies, adaptive routines, and enabling social context.

CONCLUSIONS

College students with ADHD experience profound difficulties in occupational performance, yet variation occurs across domains, attributable to occupational, biological, psychological, and social factors. Results can inform tailored interventions supporting occupational performance in this population.

A nurse-led lifestyle intervention for adult persons with attention-deficit/hyperactivity disorder (ADHD) in Sweden

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is associated with lifestyle-related diseases. Therefore, a nurse-led lifestyle intervention including interpersonal relationships, health education and cognitive support was developed to facilitate healthier lifestyle habits.Aim: The aim was to develop a lifestyle intervention and investigate its impact on mental and physical healthMethod: The 52-week intervention included 35 adults with ADHD. In a pre- and post-test design, symptoms of ADHD were measured with the Adult ADHD Self-Report Scale, quality of life was measured with the Adult ADHD Quality of Life scale and mental health was measured with the Hospital Anxiety and Depression scale. Lifestyle habits and dimensions of health were measured by the Lifestyle-Performance-Health Questionnaire and physical fitness was measured by the VO2 Max Test and calculations of waist circumference and body mass index. Result: Post-tests for a group of 25 persons showed positive changes following the intervention regarding weekly physical activity, quality of life and general and mental health. Lifestyle habit support was found to be important. The impact of the intervention should be confirmed in a long-term study with a control group.Conclusion: This intervention may be beneficial and may be implemented in a primary healthcare setting or in other open care units.

The onset and accumulation of physical multimorbidity in severe and common mental disorders

PURPOSE OF REVIEW

Despite of the heightened risks and burdens of physical comorbidities across the entire spectrum of mental disorders, relatively little is known about physical multimorbidity in this population. The aim of this narrative review is to present recent data regarding the onset and accumulation of physical multimorbidity and to assess its impact on the onset, course, treatment, and outcomes of mental disorders.

RECENT FINDINGS

A substantial body of literature shows increased risk of physical multimorbidity among people with mental disorders. The disparity in physical multimorbidity occurs even before the diagnosis of mental disorder, and the younger age group appears to be at particular risk. Numerous patterns of association between mental disorders and medical disorders involving multiple organ systems have been identified. Physical multimorbidity affects people with mental disorders across their life spans, is associated with a wide range of unfavorable outcomes and presents significant clinical and public health concerns.

SUMMARY

To address physical health inequalities among people with mental disorders compared with the general population, we must focus on the physical health from the very first point of contact with a mental health service. Treatment of mental disorders must be customized to meet the needs of patients with different physical multimorbidity patterns. Future work is needed to clarify how physical multimorbidity influences mental disorder treatment outcomes.

Sex and racial/ethnic differences in the association between childhood attention-deficit/hyperactivity disorder symptom subtypes and body mass index in the transition from adolescence to adulthood in the United States

BACKGROUND

While attention-deficit/hyperactivity disorder (ADHD) has been associated with higher body mass index (BMI), little research has focused on how this association differs by sex or race/ethnicity.

OBJECTIVE

To investigate the association between ADHD and BMI by sex and race/ethnicity (ie, European [EA], African [AA], and Hispanic American [HA]).

METHODS

Data came from the National Longitudinal Survey of Adolescent to Adult Health Waves II to IV (n = 13 332, age: 12-34 years). On the basis of self-reported childhood ADHD symptoms between the ages of 5 and 12 years, participants were categorized into: ADHD predominantly hyperactive/impulsive (ADHD-HI); ADHD predominantly inattentive (ADHD-I); ADHD combined (ADHD-C; a combination of ADHD-HI and ADHD-I symptoms); and non-ADHD.

RESULTS

The patterns of ADHD-BMI associations in the transition period between adolescence and young adulthood differed by sex and race/ethnicity. Compared with non-ADHD, ADHD-HI was associated with higher BMI among EA males and females, while ADHD-I was associated with higher BMI among EA females. ADHD-C was associated with higher BMI for HA females. We found no evidence of an association among AA males and females and HA males.

CONCLUSION

These study results suggest that the association between ADHD subtypes and BMI might differ across population subgroups in the United States.

Attention-deficit/hyperactivity disorder symptoms and perceived mental health discrimination in adults in the general population

BACKGROUND

The experience of discrimination is common in individuals with mental health problems and has been associated with a range of negative outcomes. As yet, however, there has been an absence of research on this phenomenon in adults with attention-deficit/hyperactivity disorder (ADHD). The current study examined the association between ADHD symptoms and mental health discrimination in the general adult population.

METHODS

The analytic sample comprised 7274 individuals aged 18 and above residing in private households in England that were drawn from the Adult Psychiatric Morbidity Survey, 2007. Information on ADHD was obtained with the Adult ADHD Self-Report Scale (ASRS) Screener. A single-item question was used to assess mental health discrimination experienced in the previous 12 months. Logistic regression analysis was used to examine associations.

RESULTS

The prevalence of discrimination increased as ADHD symptoms increased but was especially elevated in those with the most severe ADHD symptoms (ASRS score 18-24). In a multivariable logistic regression analysis that was adjusted for a variety of covariates including common mental disorders, ADHD symptoms (ASRS ≥ 14) were associated with almost 3 times higher odds for experiencing mental health discrimination (odds ratio: 2.81, 95% confidence interval: 1.49-5.31).

CONCLUSION

ADHD symptoms are associated with higher odds for experiencing mental health discrimination and this association is especially elevated in those with the most severe ADHD symptoms. Interventions to inform the general public about ADHD may be important for reducing the stigma and discrimination associated with this disorder in adults.

Attention-deficit/hyperactivity disorder symptoms and suicidal behavior in adult psychiatric outpatients

AIM

We aimed to examine the association between attention-deficit/hyperactivity disorder (ADHD) symptoms and suicidal behavior in psychiatric outpatients and whether this association differs among patients with different psychiatric disorders.

METHODS

Cross-sectional data came from the Japan Prevalence Study of Adult ADHD at Psychiatric Outpatient Care, which included psychiatric outpatients aged 18-65 years recruited from one university hospital and three general psychiatric outpatient clinics in Kitakyushu City, Fukuoka, Japan from April 2014 to January 2015 (N = 864). The Adult ADHD Self-Report Scale (ASRS) Screener was used to collect information on ADHD symptoms. Reports of current and lifetime suicidal behavior were also obtained. A multivariable Poisson regression analysis was used to examine the association between ADHD symptoms and suicidal behavior.

RESULTS

After adjusting for covariates there was a strong association between possible ADHD (ASRS ≥14) and suicidal behavior with prevalence ratios ranging from 1.17 (lifetime suicidal ideation) to 1.59 (lifetime suicide attempt) and 2.36 (current suicidal ideation). When ASRS strata were used, there was a dose-response association between increasing ADHD symptoms and suicidal ideation and suicide attempts. Analyses of individual ICD-10 psychiatric disorders showed that associations varied across disorders and that for anxiety disorder, ADHD symptoms were significantly linked to all forms of suicidal behavior.

CONCLUSION

ADHD symptom severity is associated with an increased risk for suicidal behavior in general psychiatric outpatients. As ADHD symptoms are common among adult psychiatric outpatients, detecting and treating ADHD in this population may be important for preventing suicidal behavior.

Post-traumatic stress symptoms are associated with physical multimorbidity: Findings from the Adult Psychiatric Morbidity Survey 2007

BACKGROUND

Studies on the association between symptoms of post-traumatic stress disorder (PTSD) and physical multimorbidity (i.e., ≥2 chronic conditions) are lacking. Thus, we assessed the association between PTSD symptoms and physical multimorbidity using nationally representative, community-based data of the UK adult population.

METHODS

Data from the 2007 Adult Psychiatric Morbidity Survey were analyzed. PTSD symptoms were assessed using the 10-item Trauma Screening Questionnaire (TSQ). A total score of ≥6 points indicated a probable PTSD. Information was collected on 20 doctor/other health professional diagnosed physical health conditions that were present in the past 12 months. Multimorbidity was defined as ≥2 physical diseases. Multivariable logistic regression and mediation analyses were conducted to analyze the association between PTSD and physical multimorbidity, and the influence of behavioral and psychological factors in this association.

RESULTS

Among 7403 individuals aged ≥16 years [mean age (SD) = 46.3 (18.6) years; 51.5% females], the prevalence of PTSD increased from 2.1% in individuals with no physical conditions to 5.4% in those with ≥4 physical conditions. After adjustment for sociodemographic factors and lifetime occurrence of a traumatic event, PTSD was associated with higher odds for physical multimorbidity (Odds Ratio [OR] = 2.47; 95% Confidence Interval [CI]: 1.71-3.56). Anxiety, depression, and disordered eating explained 35%, 21%, and 8% of the PTSD-multimorbidity association, respectively.

LIMITATIONS

Causality or temporal associations cannot be established due to the cross-sectional nature of the study. In addition, PTSD and physical conditions were assessed using self-reports.

CONCLUSIONS

PTSD symptoms may be risk factors for physical multimorbidity. Anxiety and depressive symptoms might play an important role in this association. Screening for chronic physical conditions among individuals with PTSD and treating them simultaneously may lead to better clinical outcomes.

Effects of taurine on striatal dopamine transporter expression and dopamine uptake in SHR rats

Dopaminergic deficits in the prefrontal cortex and striatum have been attributed to the pathogenesis of attention-deficit hyperactivity disorder (ADHD). Our recent study revealed that high-dose taurine improves hyperactive behavior and brain-functional signals in SHR rats. This study investigates the effect of taurine on the SHR striatum by detecting the spontaneous alternation, DA transporter (DAT) level, dopamine uptake and brain-derived neurotrophic factor (BDNF) expression. A significant increase in the total arm entries was detected in both WKY and SHR rats fed with low-dose taurine but not in those fed with high-dose taurine. Notably, significantly increased spontaneous alternation was observed in SHR rats fed with high-dose taurine. Significantly higher striatal DAT level was detected in WKY rats fed with low-dose taurine but not in SHR rats, whereas significantly reduced striatal DAT level was detected in SHR rats fed with high-dose taurine but not in WKY rats. Significantly increased dopamine uptake was detected in the striatal synaptosomes of both WKY and SHR rats fed with low-dose taurine. Conversely, significantly reduced dopamine uptake was detected in the striatal synaptosomes of SHR rats fed with high-dose taurine. Accordingly, a negative correlation was detected between striatal dopamine uptake and spontaneous alternation in SHR rats fed with low or high-dose taurine. Significantly increased BDNF was detected in the striatum of both WKY and SHR rats fed with low or high-dose taurine. These findings indicate that different dosages of taurine have opposite effects on striatal DAT expression and dopamine uptake, suggesting high-dose taurine as a possible candidate for ADHD treatment.

Physical multimorbidity and loneliness: A population-based study

Multimorbidity has been linked to a variety of negative outcomes although as yet, there has been little research on its association with loneliness. This study examined the association between physical multimorbidity (≥ 2 physical diseases) and loneliness in the general population and its potential mediators. Data came from the Adult Psychiatric Morbidity Survey 2007 (N = 7403, aged ≥16 years). Information was obtained on 20 doctor diagnosed physical conditions that were present in the previous year. An item from the Social Functioning Questionnaire (SFQ) was used to obtain information on loneliness. Multivariable logistic regression analysis was used to examine associations. An increasing number of physical diseases was associated with higher odds for loneliness. Compared to no physical diseases, the odds ratio (OR) (95% confidence interval: CI) for loneliness increased from 1.34 (1.13–1.59) to 2.82 (2.11–3.78) between one and ≥5 physical diseases. This association was particularly strong in the youngest age group (i.e. 16–44 years). The loneliness-physical multimorbidity association was significantly mediated by stressful life events (% mediated 11.1%-30.5%), anxiety (30.2%), and depression (15.4%). Physical multimorbidity is associated with increased odds for loneliness. Prospective research is now needed to further elucidate this association and the factors that underlie it.
