Cumulative determinants of adolescent health indicators: the effects of social and structural determinants of health and child sexual abuse on overdose and suicide attempt.

Background: Research has increasingly focused on the role of social and structural determinants of health (SDoH) in shaping behavioral and mental health-related outcomes, including suicide and substance use disorder. While child sexual abuse (CSA) is a well-established risk factor for these outcomes, less is known about the association with image-based sexual abuse (IBSA) and its relationship to suicide and overdose risk. Moreover, limited research has explored the interaction between abuse experiences and SDoH deficits, particularly how cumulative disadvantages may exacerbate these risks. Methods: Using a sample of young adults aged 18-28 ( Results: The likelihood of each health indicator increased with each additional SDoH deficit reported. The largest percentage-point increase was in lifetime suicide attempt, which was reported by approximately 15.2% of those with 0 SDoH compared to 49.9% of those with 4 or more SDoH deficits. There were also large differences in lifetime suicide attempt by abuse type (20.3% among those with no abuse vs. 60.6% of those with both types). Notably, across each abuse category, the predicted probabilities of suicide attempt, both before age 18 and lifetime, increased with each additional SDoH deficits. Discussion: Findings suggest that CSA and IBSA do not operate in isolation but interact with social and structural determinants in their association with key health indicators. The results highlight the need for holistic prevention and intervention strategies that address both childhood trauma and modifiable SDoH.
