Abstract
The study assessed risk factors for traumatic dental injuries (TDI) using experiences along the life course. A retrospective longitudinal study, including historical clinical data, was conducted on 16-yr-old pupils in western Norway. All first-grade pupils born in 1997 and attending public high schools were invited to participate (n=5,184). Participants responded to an electronically administered closed-ended questionnaire (39.6%, n=2,055). Information on the occurrence of TDI and events during the life course (categorized as socio-economic, biological, psychosocial, and behavioural indicators) was collected. Variables with a significant bivariate association with three different dependent variables (TDI, severity of TDI, and multiple episodes of TDI) were tested in a hierarchical logistic regression analysis. Traumatic dental injuries were more frequent among boys, adolescents of higher socio-economic status, and adolescents with adverse psychosocial and behavioural scores. Moderate and severe TDIs were more frequent among adolescents with adverse psychosocial and behavioural scores and among adolescents participating in the sport of wrestling. Multiple episodes of TDI were more frequent among adolescents with adverse psychosocial and behavioural scores and among adolescents participating in sports activities. Incorporation of different life-course indicators is important in evaluating TDI severity and repeated incidents.
Highlights
IntroductionStudies using the life-course approach have concluded that negative behaviour, socio-economic position, and adverse environmental conditions, both early and later in life, increase the risk of chronic disease and mortality [14,15]
The study was conducted among 13-yr-old Brazilians and concluded that adolescents who experienced adverse psychosocial environments along their life course had a higher incidence of traumatic dental injuries (TDIs) than their counterparts who experienced more favourable environments
For 24 pupils who had recently moved to the County of Hordaland, electronic patient journals (EPJs) data were not available; these pupils were excluded from the analysis
Summary
Studies using the life-course approach have concluded that negative behaviour, socio-economic position, and adverse environmental conditions, both early and later in life, increase the risk of chronic disease and mortality [14,15]. The study was conducted among 13-yr-old Brazilians and concluded that adolescents who experienced adverse psychosocial environments along their life course had a higher incidence of TDI than their counterparts who experienced more favourable environments. These adverse environments comprised living in non-nuclear families and experiencing high levels of paternal abuse [18]
