Social, Emotional, and Behavioral Functioning in Adolescents With Klinefelter Syndrome.

PMID 39819970WHAT IT FOUND
Boys with Klinefelter syndrome reported more anxiety and depression than peers, and parents noted greater social difficulties.
These issues appeared in childhood, not just adolescence, suggesting early monitoring and support are needed rather than waiting for puberty to begin.
Key findings
01Boys with Klinefelter syndrome had significantly higher scores for depression and anxiety on self-report measures compared to typically developing boys.
02Parents reported significantly more social difficulties and lower adaptive functioning in boys with Klinefelter syndrome compared to the control group.
03Depressive symptoms related to self-esteem and ineffectiveness were significantly worse in peri-pubertal boys with Klinefelter syndrome compared to their typically developing peers, though no difference was seen in pre-pubertal boys.

What it does not show
The study was cross-sectional, so it cannot prove that problems worsened over time due to puberty, only that they differed between groups at one point. Half of the participants with Klinefelter syndrome were diagnosed postnatally, which may introduce bias if those diagnosed prenatally have milder symptoms due to earlier intervention. The groups were not perfectly matched; boys with Klinefelter syndrome were slightly older and had lower non-verbal IQ scores than the control group, which could influence the results. The control group was recruited locally, which may limit how well the findings apply to broader populations.
Declared interests
The authors declared no conflicts of interest. The study was supported by grants from the National Institutes of Health and other foundations.
The easy way to misread this
Do not assume that social and emotional difficulties only emerge during puberty. This study found that boys with Klinefelter syndrome already had higher levels of anxiety, depression, and social problems in childhood compared to peers. Waiting for pubertal changes to start screening may miss an early window for support.
