Key Takeaway
Consider addressing modifiable factors like parental education and agreement to improve ADHD medication adherence in youth.
This meta-analysis pooled data from 63 studies involving 450,759 children and adolescents with attention deficit hyperactivity disorder (ADHD) to estimate medication adherence rates and identify associated factors. The primary outcome was the medication adherence rate, and secondary outcomes included factors influencing adherence. The pooled adherence rate was 43.6% (95% CI 39.0%–48.3%), based on 50 studies reporting absolute numbers.
Five factors were associated with improved adherence: female gender (OR = 1.07, 95% CI 1.03–1.11), fewer medication doses (OR = 0.45, 95% CI 0.27–0.75), parental agreement with the medication plan (OR = 1.87, 95% CI 1.16–3.02), single-child families (OR = 1.80, 95% CI 1.29–2.52), and medication education for parents (OR = 6.34, 95% CI 3.97–10.12). These associations were derived from meta-analysis of observational and various study designs, not from a clinical trial, so causality cannot be inferred.
The authors noted high heterogeneity in the primary analysis and sensitivity analysis, indicating variability across the included literature. This limits the precision of the pooled estimates and the generalizability of the findings. Adverse events, discontinuations, and tolerability were not reported.
For clinicians, these findings highlight potentially modifiable factors to consider when counseling families about ADHD medication adherence. In particular, parental education and agreement with the treatment plan appear strongly associated with better adherence. However, given the observational nature and heterogeneity, these factors should be viewed as associated, not causal, and individual patient circumstances remain paramount.
How this fits prior evidence
This meta-analysis extends prior coverage by quantifying ADHD medication adherence in youth, a topic not directly addressed in earlier items. It confirms the importance of family and parental factors, aligning with the prior finding that mothers report higher ADHD symptom severity than fathers, suggesting that parental perspectives may influence adherence. It also complements prior genetic and neuroimaging findings by focusing on modifiable behavioral factors. The pooled adherence rate of 43.6% underscores the clinical challenge, while the identified factors offer potential targets for intervention, though high heterogeneity limits certainty.
Managing ADHD in children and adolescents often depends on consistent medication. However, staying on track can be difficult. A large review of over 450,000 participants across 63 different studies looked at what actually helps kids stay on their prescribed treatment plans.
The data shows that several specific factors make a difference. For example, when parents are educated about the medication and agree with the treatment plan, children are much more likely to stick with it. Other factors like being in a single-child family or having fewer daily doses also showed a link to better adherence.
While these findings suggest clear ways to improve support for families, the researchers noted that there was a lot of variety in the original studies they reviewed. This means while these patterns are strong, every child's situation is unique. Talk with your doctor about how these factors might apply to your child's specific care plan.
What this means for you:
Parental education and agreement on treatment plans significantly improve medication success for children with ADHD.
Common questions
What helps children with ADHD stay on their medication?
Several factors can improve success. Parents who receive specific medication education and those who agree with the treatment plan see much better results. Additionally, having fewer daily doses and being in a single-child family were also linked to better adherence for children and adolescents.
How many kids were included in this research?
The researchers looked at data from 450,759 participants across 63 different studies. This large amount of data helped identify patterns regarding what helps children and adolescents with ADHD stay consistent with their medication plans.
Is the evidence for these findings very certain?
The study found several clear links, but it also noted high heterogeneity. This means there was a lot of variation in the original studies included in the review, so results can vary depending on the specific situation.
BackgroundMedication non-adherence is widely occurring in children and adolescents with ADHD, which may lead to adverse consequences. However, the pooled adherence rate and influencing factors are inconsistent in different studies.MethodsWe searched PubMed, Embase (Ovid), Cochrane Library, and four Chinese Databases from inception to 20 February 2024. All types of studies were included. Two researchers independently extracted data and assessed the risk of bias based on ROBINS-I, NOS, and AHRQ. A random-effects meta-analysis was conducted to pool the prevalence estimates and factors that can be combined.ResultsAfter screening 2,360 publications, 63 studies were finally included, involving 450,759 participants. The general quality of the included studies was moderate to high quality. Adherence rates were reported in 50 studies, and a pooled adherence rate was 43.6% (95% Confidence Interval [CI] 39.0%–48.3%). The sensitivity analysis shows robust study results. However, both the primary analysis and the sensitivity analysis indicated high heterogeneity. The results of Meta-analysis identified five factors influencing adherence, of which female (Odds Ratio [OR] = 1.07, 95%CI:1.03–1.11), fewer medication doses (OR = 0.45, 95%CI:0.27–0.75), parental agreement with the medication plan (OR = 1.87, 95%CI:1.16–3.02), single-child families (OR = 1.80, 95%CI:1.29–2.52), and medication education for parents (OR = 6.34, 95%CI:3.97–10.12) can improve medication adherence. Besides, we also identified seven factors influencing adherence by qualitative analysis.ConclusionMedication adherence is challenging for children and adolescents with ADHD, moreover, the meta-analysis of adherence rates showed high heterogeneity. We identified five modifiable factors by meta-analysis that are related to medication adherence, while other factors require further research.Systematic Review Registrationidentifier CRD42024514310.
