The current study analyzed data from a large national survey of families to compare child psychosocial and school outcomes, as well as parent psychosocial outcomes in youth with juvenile arthritis to youth with diabetes. It is well-established in the literature that diabetes is highly associated with increased risk for worse psychosocial outcomes (26–29). However, we found that youth with arthritis, as well as their parents, had worse psychosocial outcomes than peers with diabetes. Children with arthritis were about twice as likely to have depression, anxiety, behavior problems, and ADHD. Strikingly, youth with arthritis were nine times as likely to experience physical pain, although this is expected as pain is a direct symptom of arthritis but not of diabetes.
In terms of school outcomes, children with arthritis were similar to their peers with diabetes in school engagement and participation in clubs or organizations but had higher rates of school absenteeism and were less likely to participate in organized activities. Previous research has found that children with chronic illnesses have increased rates of school absenteeism compared to healthy peers (11), but we found that children with arthritis have increased rates of school absenteeism compared to another chronic illness group, namely diabetes. This may be related to the increased physical pain children with arthritis experience which may cause more days absent. Chronic school absenteeism is related to both short term and long term educational attainment, risky healthy behaviors, and lower income in adulthood (30–32).
We found that although parents of children with arthritis were similar to parents of children with diabetes on most outcomes, parents of children with arthritis were about twice as likely to exhibit poor mental health than parents of children with diabetes. This finding suggests that there is a need for more parental support for parents of children with arthritis. As parental mental health and social support are associated with child health outcomes (19–21), this is a group that cannot be overlooked when it comes to opportunities for additional support. Options for peer mentorship, parent support groups, acknowledgement of parent stress by providers, and referrals for care for parents may also be an important component of care for youth with arthritis. Initial work with parents of youth with type 1 diabetes indicate benefits of peer parent coaching in this population, particularly improvements in parent depressive symptoms (33). Considering increased risk in adverse mental health parental outcomes in parents of children with arthritis compared to parents of children with diabetes in the current sample, a similar model of intervention may be beneficial for parents of children with arthritis.
Importantly, the current study examined the role SDOH play in the observed differences across chronic illness groups and found that some results attenuated when accounting for SDOH, while others did not. For instance, differences between children with arthritis and diabetes in treatment for emotional or behavioral issues did attenuate when accounting for SDOH. That is, while youth with arthritis were found to be more likely to receive treatment for emotional or behavioral issues compared to youth with diabetes, this association disappeared when controlling for SDOH. This indicates that the need for mental health services in this population is particularly impacted by SDOH. This finding is consistent with previous literature that shows disparities along SDOH in mental health outcomes and access in children (34–36). Similarly, although youth with arthritis were more likely to be absent from school, this difference also attenuated when controlling for both demographics and SDOH. Children with arthritis were also less likely to participate in organized activities than children with diabetes, although this relationship was not impacted by demographic differences but was impacted by SDOH such that when accounting for SDOH, the differences disappear.
While SDOH played a role in mental health treatment, school absenteeism, and participation in organized activities, all other differences in mental health outcomes did not attenuate when accounting for SDOH. For instance, children with arthritis are at an increased likelihood to experience areas of overlap physical pain, mental health concerns including anxiety, behavioral concerns, and ADHD, as well as treatment for mental health concerns when compared to youth with diabetes. Importantly, these outcomes were not attenuated when controlling for SDOH, indicating that beyond SDOH, children with arthritis are at a greater risk for adverse mental health outcomes, including depression, anxiety, behavior problems, and ADHD. A recent study utilizing the NSCH database found important disparities related to SDOH among children with arthritis (1). Specifically, arthritis was twice as prevalent among Black youth as White youth. Furthermore, prevalence of arthritis decreased as parental education increased and prevalence rates were higher among those who experienced food insecurity than those who did not. These findings, taken together with the present study findings, highlight the importance of regularly screening for SDOH in addition to mental health concerns in order to identify youth who may need greater support. Providers should also have avenues for mental health referrals to ensure adequate care, especially for youth experiencing poverty, food insufficiency, receiving food or cash assistance, living in an unsafe neighborhood, or a neighborhood with detracting neighborhood elements, and youth with caregivers with an educational level below high school. Given the differences between illness groups and their respective care models, future research comparing care models used in endocrinology clinics and rheumatology clinics may be important to identify existing strategies that could be applied in rheumatology.
Of note, the NSCH has since changed the format of diagnosis questions, now lumping all autoimmune diseases together into one broad category. This change is particularly interesting paired with the results of the current study, as we found distinct differences in outcomes between two autoimmune illness groups, namely arthritis and diabetes. In the next iteration of the survey, we will not be able to differentiate between these two distinct illness groups and in turn, their outcomes. The analysis presented in the current study is even more important to disseminate as it is the most recent dataset from the NSCH of its kind, with the ability to compare across illness groups.
As with any study, it is important to acknowledge the limitations of the current study. The present study utilized a national database, which limited our analyses to the variables available in this database. As such, there may be additional relevant variables of interest we were unable to analyze. Furthermore, the database was cross-sectional, which limits our ability to draw conclusions about causality and directionality. The nature of the surveys relied on responses to mailings, which may have skewed the sample to those who are interested in research and trust authorities. Lastly, the surveys were only available in English and Spanish, and may have excluded a number of populations due to language barriers.
Notably, the present study had a number of strengths, including the use of a national database that allowed for larger sample sizes than typical diabetes and arthritis studies, as well as a diverse sample pulled from across the US. In addition, while most diabetes and arthritis studies are conducted within the disease group or compared to healthy controls, the present study compared two unique auto-immune illness groups, allowing for a more nuanced understanding of the outcomes. Furthermore, this comparison opens a dialogue about comparing care models such that we can apply strategies from one illness group’s care model to the other.
