The results suggest that being older, living in rural areas, and reporting tooth pain in the last 6 months may influence the QoLROH of patients undergoing hemodialysis.
Objectives To investigate the spatial and spatial‐temporal distribution of oral and maxillofacial injuries caused by urban violence, as well as to identify underlying disparities at regional level through a geostatistical approach. Methods This was a historical ecological cohort study of trauma cases caused by urban violence using aggregate data from victims assisted in a Brazilian medical‐forensic service between January 2012 and December 2015. The longitudinal patterns of change observed in each geographic area (neighbourhoods) were evaluated using the finite mixture model (FMM). The spatial autocorrelation of events was investigated using the Getis‐Ord Indicator (Gi*) to identify significant hot and cold spatial clusters. With a spatial regression model, it was also found when socioeconomic variables, residential infrastructure and neighbourhood infrastructure were associated with high incidence rates. The significance level was set at P ≤ 0.05. Results The finite mixture model revealed three different patterns of longitudinal trajectory of the incidence of oral and maxillofacial trauma caused by urban violence (TP1 to TP3, P < 0.05). TP1 was characterized by an incidence that remained stable and high over time, comprising 17.4% of the city's neighbourhoods. In TP2, it was observed that the incidence was moderate, with a slightly increasing trend in the last year evaluated, representing around 41.8% of the sample. In contrast, in TP3, it was found that the incidence was relatively low and remained stable over time, accounting for about 40.8% of the sample. The Getis‐Ord (Gi*) statistic identified significant high‐risk clusters in the western (P < 0.05), southern (P < 0.05), and eastern regions (P < 0.05) and low risk in the northern region (P < 0.05). The spatial regression model indicated significant association between areas with unfavourable socioeconomic conditions and higher incidence of events (β = 0.178, SE = 0.046, P < 0.001). Conclusions Clusters demarcating areas with high socio‐spatial vulnerability for urban violence and oral and maxillofacial injuries were identified. The findings highlight the need to improve living conditions in segregated urban areas and develop intersectoral actions to improve living conditions, employment, public safety, social support, health care and prevention.
Background Physical violence against children and adolescents comprises a serious public health problem and often results in oral and maxillofacial traumas. Social determinants may favour the occurrence of these events, but few studies have critically evaluated the interaction between social and geographical risk factors. Aims To investigate the spatiotemporal distribution of oral and maxillofacial traumas resulting from violence against children and adolescents through geostatistical techniques. Methods This study was an ecological analysis of cases of trauma caused by violence against Brazilian children and adolescents using aggregated data from victims attended at a Center of Forensic Medicine and Forensic Dentistry between January 2012 and December 2015. Data were analysed through modelling based on geographic information system (GIS). Results Two distinct patterns of longitudinal trajectory of oral and maxillofacial trauma related to violence against children and adolescents were identified (TP1 and TP2, P < 0.05). The spatial regression analysis revealed a statistically significant association between higher incidence of cases and areas with worse socioeconomic conditions (β = 0.047, SE = 0.020, P < 0.05). Conclusion Neighbourhoods with considerable socio‐spatial vulnerability for violence against children and adolescents and maxillofacial traumas were identified.
