          Abstract

          Objectives

          To investigate the risk of emergency hospital admissions for violence (EHAV) associated with demographic and socioeconomic factors in Wales between 2007/2008 and 2013/2014, and to describe the site of injury causing admission.

          Design

          Database analysis of 7 years’ hospital admissions using the Patient Episode Database for Wales (PEDW).

          Setting and participants

          Wales, UK, successive annual populations ∼2.8 million aged 0–74 years.

          Primary outcome

          The first emergency admission for violence in each year of the study, defined by the International Classification of Diseases V.10 (ICD-10) codes for assaults (X85-X99, Y00-Y09) in any coding position.

          Results

          A total of 11 033 admissions for assault. The majority of admissions resulted from head injuries. The overall crude admission rate declined over the study period, from 69.9 per 100 000 to 43.2 per 100 000, with the largest decrease in the most deprived quintile of deprivation. A generalised linear count model with a negative binomial log link, adjusted for year, age group, gender, deprivation quintile and settlement type, showed the relative risk was highest in age group 18–19 years (RR=6.75, 95% CI 5.88 to 7.75) compared with the reference category aged 10–14 years. The risk decreased with age after 25 years. Risk of admission was substantially higher in males (RR=4.55, 95% CI 4.31 to 4.81), for residents of the most deprived areas of Wales (RR=3.60, 95% CI 3.32 to 3.90) compared with the least deprived, and higher in cities (RR=1.37, 95% CI 1.27 to 1.49) and towns (RR=1.32, 95% CI 1.21 to 1.45) compared with villages.

          Conclusions

          Despite identifying a narrowing in the gap between prevalence of violence in richer and poorer communities, violence remains strongly associated with young men living in areas of socioeconomic deprivation. There is potential for a greater reduction, given that violence is mostly preventable. Recommendations for reducing inequalities in the risk of admission for violence are discussed.

          Child maltreatment in the "children of the nineties": a cohort study of risk factors.

          To analyze the multiple factors affecting the risk of maltreatment in young children within a comprehensive theoretical framework. The research is based on a large UK cohort study, the Avon Longitudinal Study of Parents and Children. Out of 14,256 children participating in the study, 293 were investigated by social services for suspected maltreatment and 115 were placed on local child protection registers prior to their 6th birthday. Data on the children have been obtained from obstetric data and from a series of parental questionnaires administered during pregnancy and the first 3 years of life. Risk factors have been analyzed using an hierarchical approach to logistic regression analysis. In the stepwise hierarchical analysis, young parents, those with low educational achievement, and those with a past psychiatric history or a history of childhood abuse were all more likely to be investigated for maltreatment, or to have a child placed on the child protection register, with odds ratios between 1.86 and 4.96 for registration. Examining strength of effect, the highest risks were found with indicators of deprivation (3.24 for investigation and 11.02 for registration, after adjusting for parental background factors). Poor social networks increased the risk of both investigation (adjusted OR 1.93) and registration (adjusted OR 1.90). Maternal employment seemed to reduce the risk of both outcomes but adjusted odds ratios were no longer significant for registration. After adjusting for higher order confounders, single parents and reordered families were both at higher risk of registration. Reported domestic violence increased the risk of investigation and registration but this was no longer significant after adjusting for higher order variables. Low birthweight children were at higher risk of registration as were those whose parents reported few positive attributes of their babies. This study supports previous research in the field demonstrating that a wide range of factors in the parental background, socio-economic and family environments affect the risk of child maltreatment. By combining factors within a comprehensive ecological framework, we have demonstrated that the strongest risks are from socio-economic deprivation and from factors in the parents' own background and that parental background factors are largely, but not entirely, mediated through their impact on socio-economic factors.

            Long-term effects of home visitation on maternal life course and child abuse and neglect. Fifteen-year follow-up of a randomized trial.

            Home-visitation services have been promoted as a means of improving maternal and child health and functioning. However, long-term effects have not been examined. To examine the long-term effects of a program of prenatal and early childhood home visitation by nurses on women's life course and child abuse and neglect. Randomized trial. Semirural community in New York. Of 400 consecutive pregnant women with no previous live births enrolled, 324 participated in a follow-up study when their children were 15 years old. Families received a mean of 9 home visits during pregnancy and 23 home visits from the child's birth through the second birthday. DATA SOURCES AND MEASURES: Women's use of welfare and number of subsequent children were based on self-report; their arrests and convictions were based on self-report and archived data from New York State. Verified reports of child abuse and neglect were abstracted from state records. During the 15-year period after the birth of their first child, in contrast to women in the comparison group, women who were visited by nurses during pregnancy and infancy were identified as perpetrators of child abuse and neglect in 0.29 vs 0.54 verified reports (P<.001). Among women who were unmarried and from households of low socioeconomic status at initial enrollment, in contrast to those in the comparison group, nurse-visited women had 1.3 vs 1.6 subsequent births (P=.02), 65 vs 37 months between the birth of the first and a second child (P=.001), 60 vs 90 months' receiving Aid to Families With Dependent Children (P=.005), 0.41 vs 0.73 behavioral impairments due to use of alcohol and other drugs (P=.03), 0.18 vs 0.58 arrests by self-report (P<.001), and 0.16 vs 0.90 arrests disclosed by New York State records (P<.001). This program of prenatal and early childhood home visitation by nurses can reduce the number of subsequent pregnancies, the use of welfare, child abuse and neglect, and criminal behavior on the part of low-income, unmarried mothers for up to 15 years after the birth of the first child.

              An assessment of maxillofacial fractures: a 5-year study of 237 patients.

              This descriptive analytical study assesses the cause, type, incidence, demographic, and treatment data of maxillofacial fractures managed at our medical center during a 5-year period and compares them with the existing body of literature on the subject. A 5-year retrospective clinical and epidemiologic study evaluated 237 patients treated for maxillofacial fractures from 1996 to 2001 at one medical center. There were 211 male patients (89%) and 26 (11%) female patients. The patients ranged in age from 3 to 73 years, with 59.0% (140 patients) in the 20- to 29-year age group. A number of parameters, including age, gender, cause of injury, site of injury, type of injury, treatment modalities, and complications, were evaluated. All maxillofacial injuries were assessed and treated by a single oral and maxillofacial surgeon. Other concomitant bodily injuries were treated by appropriate consultant specialists. There were 173 (72.9%) mandibular, 33 (13.9%) maxillary, 32 (13.5%) zygomatic, 57 (24.0%) zygomatico-orbital, 5 (2.1%) cranial, 5 (2.1%) nasal, and 4 (1.6%) frontal injuries. Car accidents caused 73 (30.8%), motorcycle accidents caused 55 (23.2%), altercations 23 (9.7%), sports 15 (6.3%), and warfare caused 23 (9.7%) of the maxillofacial injuries. Regarding distribution of mandibular fractures, 32% were seen in the condylar region, 29.3% in the symphyseal-parasymphyseal region, 20% in the angle region, 12.5% in the body, 3.1% in the ramus, 1.9% in the dentoalveolar, and 1.2% in the coronoid region. The distribution of maxillary fractures was Le Fort II in 18 (54.6%), Le Fort I in 8 (24.2%), Le Fort III in 4 (12.1%), and alveolar in 3 (9.1%). Of the 173 mandibular fractures, 56.9% were treated by closed reduction, 39.8% by open reduction, and 3.5% by observation only. Of 33 maxillary fractures, 54.6% were treated using closed reduction, 40.9% using open reduction, and 4.5% with observation only. Approximately 52.1% of the patients were treated under general anesthesia, and 47.9% were treated under local anesthesia and sedation. Postsurgical complications were recorded in 5% of patients. These complications included infection, asymmetry, and malocclusion. Overall mortality in this series was 0.84% (2 patients); mortality was caused by pulmonary infection. The findings of this study, compared with similar studies reported in the literature, support the view that the causes and incidence of maxillofacial injuries vary from 1 country to another.
