Accidental Injuries in Preschoolers: Are We Missing an Opportunity for Early Assessment and Intervention?

Frequent Pain is Common Among 10-11-Year-Old Children with Symptoms of Attention Deficit Hyperactivity Disorder

Purpose

Adults with neurodevelopmental disorders have an increased risk for chronic pain. This study aimed to describe the prevalence of frequent and multisite pain among children with symptoms of attention deficit hyperactivity disorder (ADHD) and explore potential sex differences in pain prevalence.

Participants and Methods

Children born in 2008 included in the "Halland Health and Growth Study" were invited to a follow-up (n = 1186) in 2018-19. Parents received a digital screening questionnaire, the Swanson, Nolan and Pelham Rating Scale (SNAP-IV) for ADHD, and the children answered a pain questionnaire that included a pain mannequin. The main outcome was pain experience, and children with symptoms of ADHD were compared to children without these symptoms.

Results

In this general population of 10-11-year-old Swedish children, weekly pain was reported in 52.5% of children with symptoms of ADHD combined type, compared to 36.2% of children without these symptoms (p < 0.05). Hyperactivity and impulsivity were significant contributors to the increased risk for frequent pain (OR 2.33 95% CI 1.30 to 4.17, p = 0.004), but inattention was not a significant contributor (OR 1.17 95% CI 0.74 to 1.87, p = 0.497). Multisite pain was more common among girls with hyperactivity compared to boys with hyperactivity (51.4 vs 27.9%, p = 0.036). Weekly headache and/or abdominal pain was reported by a quarter of girls with symptoms of ADHD combined type, and up to a fifth of boys, compared to 11-13% of children without these symptoms.

Conclusion

Frequent pain was more common for children with symptoms of ADHD compared to children without symptoms of ADHD. Hyperactivity and impulsivity had a stronger association to pain than had inattention-related problems. Clinicians should be aware of the frequent occurrence and the association between pain and neurodevelopmental disorders among children, and that it could complicate both the clinical picture and the treatment.

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.

Temporal trends in lung cancer mortality and years of life lost in Wuhan, China, 2010-2019

Objective

Lung cancer is responsible for millions of deaths yearly, and its burden is severe worldwide. This study aimed to investigate the burden of lung cancer in the population of Wuhan based on the surveillance data from 2010 to 2019.

Methods

Data of this study was obtained from the Mortality Register System established by the Wuhan Center for Disease Control and Prevention. The study systematically analyzed the burden of lung cancer deaths in the population of Wuhan and its 13 administrative regions from 2010 to 2019 via the Joinpoint regression models, Age-Period-Cohort (APC) models, and decomposition analysis.

Results

This study found the upward and downward trends in the age-standardized mortality rates (ASMRs) and age-standardized years of life lost rates (ASYLLRs) of lung cancer from 2010 to 2019. In Joinpoint regression models, the corresponding estimated annual percentage change (EAPC) were 1.00% and -1.90%, 0.60%, and -3.00%, respectively. In APC models, lung cancer mortality tended to increase with age for both sexes in Wuhan, peaking at the 85-89 age group; The period effects for different populations have started to gradually decline in recent years. In addition, the cohort effects indicated that the risk of lung cancer death was highest among those born in the 1950s-1955s, at 1.08 (males) and 1.01 (females). Among all administrative districts in Wuhan, the ASMR of lung cancer in the Xinzhou District has remained the highest over the study period. In decomposition analysis, both population aging (P&lt;0.01) and population growth (P&lt;0.01) aggravated (Z&gt;0) lung cancer deaths in the Wuhan population.

Conclusions

The burden of lung cancer death in the Wuhan population has shown a gradual decline in recent years, but the impact of aging and population growth on lung cancer mortality should not be ignored. Therefore, lung cancer surveillance must be strengthened to reduce the burden of lung cancer in Wuhan.

Focusing on Young Children in Pediatric Psychology Research: Introduction to the Special Issue on Young Children

This special issue focusing on pediatric psychology research in young children highlights 15 papers that focus on infants through preschoolers. Studies selected for inclusion cover a range of pediatric health conditions such as food allergy, medical trauma, injuries/traumatic brain injury, cancer, inflammatory bowel disease, pain, and sleep. The inherent challenges of researching young children are described, and studies vary in their methods for assessment and intervention; multiple studies include an observational component or developmental evaluation. Six of the studies employ diverse samples of children and/or parents and demonstrate the feasibility as well as importance of increasing our understanding of factors related to health disparities. Taken together, the special issue demonstrates the high quality of research focusing on young children. As the special issue editors, we hope this collection will spark an interest in others to focus on research with young children across pediatric populations.
