Associations between adverse childhood experiences and oral health in Norwegian adults, and the impact of social support and adulthood revictimization. The HUNT4 Survey.

Adverse childhood experiences (ACEs) increase the risk of various health issues, including oral problems. ACEs also heighten the risk of revictimization, though the impact of adulthood revictimization on oral health is less understood. Conversely, positive influences, such as a trusted adult in childhood, may buffer these effects. This study examines how different dimensions of adversity relate to oral health. This cross-sectional study included 37 559 adults from the HUNT4 Survey, a general population study in Norway. We examined distinct ACE exposures: (i) specific ACEs (i.e. sexual, physical and psychological abuse, bully victimization, parental divorce, and death of a parent), (ii) cumulative ACE, (iii) combined exposure of ACE and adult support, and (iv) adversity trajectories identified by group-based trajectory modelling of ACE and adulthood sexual, physical and psychological abuse. Associations with oral health were assessed by logistic regression, estimating odds ratios with 95% confidence intervals. Most ACE types were associated with poorer adult oral health outcomes, exhibiting a dose-response gradient, where one-unit ACE increase indicated a higher likelihood of self-reported poor dental health (28%), dental fear (31%), and no dental visit in the last 2 years (10%). Combined exposure of ACE and adult support showed that those with high support had lower odds of reporting poor oral health. The revictimized trajectory exhibited the strongest association with impaired oral health outcomes. Our findings support that ACEs are linked to poor oral health later in life, especially among those revictimized as adults, whilst supportive childhood relations may buffer this effect.
