Suicide risk with ASD traits or ADHD traits in non-clinical young adults

Abstract

Abstract The impact of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) traits on suicidal thoughts and behaviors (STBs) remains inadequately explored. Hence, the present study aims to delve deeper into these intricate issues, contributing to a better understanding of these complex challenges among Chinese youth. The data of 90,882 participants was collected from 63 Chinese universities and colleges in Jilin, China. We aim to explore the risks of STBs on ASD, ADHD, and co-occurrence of ASD + ADHD by using the Autism Spectrum Quotient-10 items (AQ-10) and Adult ADHD Self Report Scale (ASRS). Propensity score matching (PSM) was implemented to balance demographical variables across the four groups. Binary logistic regression was then conducted to further analyze and compare suicide risk across the four groups, also accounting for sex differences. Suicide risks were significantly higher in the ADHD (OR = 1.24, p < 0.001) and ASD + ADHD(OR = 1.49, p < 0.001) traits group. However, there was no significant difference in suicide risk between the ASD traits group (OR = 1.00, p = 1.00) and the control group. The risk of suicide was significantly higher for females than for males across all four groups (p < 0.001). These results indicate the importance of screening for ASD + ADHD traits in young adults, especially females due to its higher risk of STBs. Further studies are warranted to delve deeper into this issue, emphasizing the necessity of formal diagnostic tests and directing focused attention toward addressing these complexities.
