Abstract
Exposure to violence is common in South Africa. Yet, few studies examine how violence exposure contributes to South African adolescents' participation in youth violence. The aims of this study were to examine effects of different violence exposures on violent attitudes and behavior, to test whether attitudes mediated effects of violence exposures on violent behavior, and to test whether adult involvement had protective or promotive effects. Questionnaires were administered to 424 Zulu adolescents in township high schools around Durban, South Africa. Structural equation modeling (SEM) was used to test associations among violence exposures and both violent attitudes and behavior. Victimization, witnessing violence, and friends' violent behavior contributed directly to violent behavior. Only family conflict and friends' violence influenced violent attitudes. Attitudes mediated effects of friends' violence on violent behavior. Multiple-group SEM indicated that adult involvement fit a protective model of resilience. These findings are discussed regarding their implications for prevention.

Abstract
Homicide rates for South African children were estimated at double the global average in 2000. This article presents a secondary data analysis of the National Injury Mortality Surveillance System (NIMSS), with full coverage in four major metropolitan cities. Child homicide rates for 2001-2005 were calculated within the 0-4, 5-9 and 10-14 year age groups. The homicide rates were similar to the global pattern, with higher rates for boys, and among children aged 0-4 years than for older children. Poisson regression, accounting for city level clustering, was used to investigate age, sex and period effects in the homicide rate. The model indicated that the gender difference was more marked in the 10-14 year age groups (RR = 2.17; 95% CI 1.97-2.38) than in the 5-9 year (RR = 1.43; 95% CI 1.27-1.62) with the 0-4 year age group in-between (RR = 1.80; 95% CI 1.55-2.10). These data confirm previous observations that fatal violence among children is a public health concern, but, given the high rates of homicide among South African adults and other competing public health problems, it is difficult to motivate for action to address the issue of violence against children. Nonetheless, there are sufficient indications that efforts to reduce childhood violence are urgently needed.

Abstract
BACKGROUND Current methods of measuring the population burden of injuries rely on many assumptions and limited data available to the global burden of diseases (GBD) studies. The aim of this study was to compare the population burden of injuries using different approaches from the UK Burden of Injury (UKBOI) and GBD studies. METHODS AND FINDINGS The UKBOI was a prospective cohort of 1,517 injured individuals that collected patient-reported outcomes. Extrapolated outcome data were combined with multiple sources of morbidity and mortality data to derive population metrics of the burden of injury in the UK. Participants were injured patients recruited from hospitals in four UK cities and towns: Swansea, Nottingham, Bristol, and Guildford, between September 2005 and April 2007. Patient-reported changes in quality of life using the EQ-5D at baseline, 1, 4, and 12 months after injury provided disability weights used to calculate the years lived with disability (YLDs) component of disability adjusted life years (DALYs). DALYs were calculated for the UK and extrapolated to global estimates using both UKBOI and GBD disability weights. Estimated numbers (and rates per 100,000) for UK population extrapolations were 750,999 (1,240) for hospital admissions, 7,982,947 (13,339) for emergency department (ED) attendances, and 22,185 (36.8) for injury-related deaths in 2005. Nonadmitted ED-treated injuries accounted for 67% of YLDs. Estimates for UK DALYs amounted to 1,771,486 (82% due to YLDs), compared with 669,822 (52% due to YLDs) using the GBD approach. Extrapolating patient-derived disability weights to GBD estimates would increase injury-related DALYs 2.6-fold. CONCLUSIONS The use of disability weights derived from patient experiences combined with additional morbidity data on ED-treated patients and inpatients suggests that the absolute burden of injury is higher than previously estimated. These findings have substantial implications for improving measurement of the national and global burden of injury.

Abstract
The value of measuring the population burden of fatal and nonfatal injury is well established. Population health metrics are important for assessing health status and health-related quality of life after injury and for integrating mortality, disability, and quality-of-life consequences. A frequently used population health metric is the disability-adjusted life-year. This metric was launched in 1996 in the original Global Burden of Disease and Injury study and has been widely adopted by countries and health development agencies alike to identify the relative magnitude of different health problems. Apart from its obvious advantages and wide adherence, a number of challenges are encountered when the disability-adjusted life-year is applied to injuries. Validation of disability-adjusted life-year estimates for injury has been largely absent. This paper provides an overview of methods and existing knowledge regarding the population burden of injury measurement. The review of studies that measured burden of injury shows that estimates of the population burden remain uncertain because of a weak epidemiologic foundation; limited information on incidence, outcomes, and duration of disability; and a range of methodological problems, including definition and selection of incident and fatal cases, choices in selection of assessment instruments and timings of use for nonfatal injury outcomes, and the underlying concepts of valuation of disability. Recommendations are given for methodological refinements to improve the validity and comparability of future burden of injury studies.

Abstract
BACKGROUND The mortality rate from unnatural deaths for South Africa is nearly double the world average. Reliable data are limited by inaccurate and incomplete ascertainment of specific causes of unnatural death. This study describes trends in causes of unnatural death between 1992 and 2008 in a cohort of South African miners. METHODOLOGY/PRINCIPAL FINDINGS The study used routinely-collected retrospective data with cause of death determined from multiple sources including the mine's human resources database, medical records, death registration, and autopsy. Cause-specific mortality rates and Poisson regression coefficients were calculated by calendar year and age group. The cohort included 40,043 men. One quarter of all 2937 deaths were from unnatural causes (n = 805). Causes of unnatural deaths were road traffic accidents 38% (109/100,000 py), homicides 30% (88/100,000 py), occupational injuries 17% (50/100,000 py), suicides 8% (24/100,000 py), and other accidents 6% (19/100,000 py). Rates of unnatural deaths declined by 2% (95%CI -4%,-1%) per year over the study period, driven by declining rates of road traffic and other accidents. The rate of occupational injury mortality did not change significantly over time (-2% per year, 95%CI -5%,+2%). Unnatural deaths were less frequent in this cohort of workers than in the South African population (IRR 0.89, 95%CI 0.82-0.95), particularly homicides (IRR 0.48, 95%CI 0.42-0.55). CONCLUSIONS/SIGNIFICANCE Unnatural deaths were a common cause of preventable and premature death in this cohort of miners. While unnatural death rates declined between 1992 and 2008, occupational fatalities remained at a high level. Evidence-based prevention strategies to address these avoidable deaths are urgently needed.

Abstract
OBJECTIVES There are few reports on epidemiological patterns of injury and injury-related mortality in developing countries. This study aimed to report the epidemiology of injuries and poisonings in emergency departments in Iran. STUDY DESIGN Retrospective study using available data from 20 March 2005 to 19 March 2008. METHODS Recorded Injury Surveillance System (ISS) data including demographics, place of residence, type of injury, and outcome during emergency department stay were extracted from the databank of the national ISS and included in the final analysis. RESULTS In total, 2,991,624 emergency department admissions due to injury were recorded at university hospitals during the study period. According to the national census in 2006, Iran had a population of 70,472,846, so the injury admission rate to university hospital emergency departments was 1.4%/year in Iran. The mean age of the patients was 26.5 [standard deviation (SD) 16.9] years, and 72.7% of the cases were male. The most common cause of injury was road traffic accidents (RTAs) (31.9%), followed by hit (25.5%) and falls (10.9%). Intoxication was associated with 5.3% of all injuries. The overall emergency department mortality rate was 0.6%. Of those who died, the mean age was 32.6 (SD 21.1) years. All fatal injuries, except burn injuries, were more common in males. Intoxication-related deaths occurred in 3.8% of cases. In patients aged <13, 13-65 and >65 years, hit (28.2%), RTAs (34%) and RTAs (27.9%) were, respectively, the most common causes of injury. In all age groups, RTAs were the most common cause of death. CONCLUSIONS This study determined the epidemiology of injuries and poisonings in emergency departments in Iran. The mortality rate in this study was low in comparison with other research, which may be explained in the context of inappropriate prehospital or interhospital care in Iran. This finding can be employed to formulate targeted preventive strategies based on the incidence of the more common types of injury.

Abstract
Despite a high prevalence of intimate partner violence in South Africa, few epidemiological studies have assessed individual risk factors and differential vulnerability by gender. This study seeks to analyze gender differences in risk for intimate partner violence victimization and perpetration according to childhood and adult risk factors in a national sample of South African men and women. Using data from the cross-sectional, nationally representative South Africa Stress and Health Study, the authors examine data from 1,715 currently married or cohabiting adults on reporting of intimate partner violence. Our analysis include (a) demographic factors, (b) early life risk factors (including exposure to childhood physical abuse, witnessing parental violence, parental closeness, and early onset DSM-IV disorders), and (c) adult risk factors (including experiencing the death of a child and episodes of DSM-IV disorders after age 20). Although prevalence rates of intimate partner violence are high among both genders, women are significantly more likely than men to report being victimized (29.3% vs. 20.9%). Rates of perpetrating violence are similar for women and men (25.2% and 26.5%, respectively). Men are more likely to report predictive factors for perpetration, whereas women are more likely to report predictors for victimization. Common risk factors among men and women reporting perpetration include exposure to childhood physical abuse, witnessing parental violence, and adult onset alcohol abuse/dependence. However, risk factors in male perpetrators are more likely to include cohabitation, low income, and early and adult-onset mood disorders, whereas risk factors in female perpetrators include low educational attainment and early onset alcohol abuse/dependence. The single common risk factor for male and female victims of partner violence is witnessing parental violence. Additional risk factors for male victims are low income and lack of closeness to a primary female caregiver, whereas additional risk factors for female victims are low educational attainment, childhood physical abuse, and adult onset alcohol abuse/dependence and intermittent explosive disorder. Intimate partner violence is a significant public health issue in South Africa, strongly linked to intergenerational cycling of violence and risk exposure across the life course. These findings indicate that gender differences in risk and common predictive factors, such as alcohol abuse and exposure to childhood violence, should inform the design of future violence-prevention programs and policies.

Abstract
Background Little evidence on the burden of disease has been reported about Guinea. This study was conducted to demonstrate the morbidity burden in Guinea and provide basic evidence for setting health priorities. Methods A retrospective descriptive study was designed to present the morbidity burden of Guinea. Morbidity data were extracted from the National Health Statistics Report of Guinea of 2008. The data are collected based on a pyramid of facilities which includes two national hospitals (teaching hospitals), seven regional hospitals, 26 prefectural hospitals, 8 communal medical centers, 390 health centers, and 628 health posts. Morbidity rates were calculated to measure the burden of non-fatal diseases. The contributions of the 10 leading diseases were presented by sex and age group. Results In 2008, a total of 3,936,599 cases occurred. The morbidity rate for males was higher than for females, 461 versus 332 per 1,000 population. Malaria, respiratory infections, diarrheal diseases, helminthiases, and malnutrition ranked in the first 5 places and accounted for 74% of the total burden, respectively having a rate of 148, 64, 33, 32, and 14 per 1,000 population. The elderly aged 65+ had the highest morbidity rate (611 per 1,000 population) followed by working-age population (458 per 1,000 population) and children (396 per 1,000 population) while the working-age population aged 25-64 contributed the largest part (39%) to total cases. The sex- and age-specific spectrum of morbidity burden showed a similar profile except for small variations. Conclusion Guinea has its unique morbidity burden. The ten leading causes of morbidity burden, especially for malaria, respiratory infections, diarrheal diseases, helminthiases, and malnutrition, need to be prioritized in Guinea.

Abstract
Injury is a major public health issue, responsible for 5 million deaths each year, equivalent to the total mortality caused by HIV, malaria and tuberculosis combined. The World Health Organisation estimates that of the total worldwide deaths due to injury, more than 90% occur in low- and middle-income countries (LMIC). Despite the burden of injury sustained by LMIC, there are few continuing injury surveillance systems for collection and analysis of injury data. We describe a hospital-based trauma surveillance instrument for collection of a minimum data-set for calculating common injury scoring metrics including the Abbreviated Injury Scale and the Injury Severity Score. The Cape Town Trauma Registry (CTTR) is designed for injury surveillance in low-resource settings. A pilot at Groote Schuur Hospital in Cape Town was conducted for one month to demonstrate the feasibility of systematic data collection and analysis, and to explore challenges of implementing a trauma registry in a LMIC. Key characteristics of the CTTR include: ability to calculate injury severity, key minimal data elements, expansion to include quality indicators and minimal drain on human resources based on few fields. The CTTR provides a strategy to describe the distribution and consequences of injury in a high trauma volume, low-resource environment.

Abstract
OBJECTIVE To estimate injury mortality rates in a rural population in KwaZulu-Natal, South Africa and to identify socio-demographic risk factors associated with adult injury-related deaths. METHODS The study used population-based mortality data collected by a demographic surveillance system on all resident and non-resident members of 11,000 households. Deaths and person-years of observation (pyo) were aggregated for individuals between 01 January 2000 and 31 December 2007. Cause of death was determined by verbal autopsy, coded using ICD-10 and further categorised using global burden of disease categories. Socio-demographic risk factors associated with injuries were examined using regression analyses. RESULTS We analysed data on 133,483 individuals with 717,584.6 person-years of observation (pyo) and 11,467 deaths. Of deaths, 8.9% were because of injury-related causes; 11% occurred in children <15 years old. Homicide, road traffic injuries and suicide were the major causes. The estimated crude injury mortality rate was 142.4 (134.0, 151.4)/100,000 pyo; 116.9 (108.1, 126.5)/100,000 pyo among residents and 216.8 (196.5, 239.2)/100,000 pyo among non-residents. In multivariable analyses, the differences between residents and non-residents remained but were no longer significant for women. In men and women, full-time employment was significantly associated with lower mortality [adjusted rate ratios 0.6 (0.4, 0.9); 0.4 (0.2, 0.9)]; in men, higher asset ownership was independently associated with increased mortality [adjusted rate ratio 1.5 (1.1, 1.9)]. CONCLUSIONS Reducing the high levels of injury-related mortality in South Africa requires intersectoral primary prevention efforts that redress the root causes of violent and accidental deaths: social inequality, poverty and alcohol abuse.

Abstract
Emerging out of a larger study whose main focus was to identify the risk and protective factors in male interpersonal violence, and based on analysis of local and global empirical and theoretical literature, the main aim of this article is to develop a conceptual foundation for understanding and preventing male interpersonal violence in South Africa within the context of responsive local manifestation and dynamics of male violence. The conceptual foundation developed has been informed by both public health and social science perspectives. The impetus for the development of a conceptual foundation is not only the scale of the problem of violence in the country but, more importantly, the urgent need for a theoretically sound, locally-grounded and better-integrated understanding of male interpersonal violence and violence generally. The article describes violence in a global context before turning to violence in South Africa. Then it briefly looks at different theoretical approaches on violence before focusing on the public health approach to violence generally, and male interpersonal violence more specifically. Next it describes the ecological framework, given that this perspective tends to accompany the public health studies in violence. A critical appraisal of this approach is then offered. Finally, the article attempts to bring together these disparate perspectives in the process of developing a locally responsive, social science-informed critical public health conceptual framework on male interpersonal violence, drawing on and including a focus on the political, economic and social history of South Africa.

Abstract
BACKGROUND Burden of disease estimates for South Africa have highlighted the particularly high rates of injuries related to interpersonal violence compared with other regions of the world, but these figures tell only part of the story. In addition to direct physical injury, violence survivors are at an increased risk of a wide range of psychological and behavioral problems. This study aimed to comprehensively quantify the excess disease burden attributable to exposure to interpersonal violence as a risk factor for disease and injury in South Africa. METHODS The World Health Organization framework of interpersonal violence was adapted. Physical injury mortality and disability were categorically attributed to interpersonal violence. In addition, exposure to child sexual abuse and intimate partner violence, subcategories of interpersonal violence, were treated as risk factors for disease and injury using counterfactual estimation and comparative risk assessment methods. Adjustments were made to account for the combined exposure state of having experienced both child sexual abuse and intimate partner violence. RESULTS Of the 17 risk factors included in the South African Comparative Risk Assessment study, interpersonal violence was the second leading cause of healthy years of life lost, after unsafe sex, accounting for 1.7 million disability-adjusted life years (DALYs) or 10.5% of all DALYs (95% uncertainty interval: 8.5%-12.5%) in 2000. In women, intimate partner violence accounted for 50% and child sexual abuse for 32% of the total attributable DALYs. CONCLUSIONS The implications of our findings are that estimates that include only the direct injury burden seriously underrepresent the full health impact of interpersonal violence. Violence is an important direct and indirect cause of health loss and should be recognized as a priority health problem as well as a human rights and social issue. This study highlights the difficulties in measuring the disease burden from interpersonal violence as a risk factor and the need to improve the epidemiological data on the prevalence and risks for the different forms of interpersonal violence to complete the picture. Given the extent of the burden, it is essential that innovative research be supported to identify social policy and other interventions that address both the individual and societal aspects of violence.

According to the World Health Organization, unintentional injuries were responsible for over 3.9 million deaths and over 138 million disability-adjusted life-years in 2004, with over 90% of those occurring in low- and middle-income countries (LMIC). This paper utilizes the year 2004 World Health Organization Global Burden of Disease Study estimates to illustrate the global and regional burden of unintentional injuries and injury rates, stratified by cause, region, age, and gender. The worldwide rate of unintentional injuries is 61 per 100,000 population per year. Overall, road traffic injuries make up the largest proportion of unintentional injury deaths (33%). When standardized per 100,000 population, the death rate is nearly double in LMIC versus high-income countries (65 vs. 35 per 100,000), and the rate of disability-adjusted life-years is more than triple in LMIC (2,398 vs. 774 per 100,000). This paper calls for more action around 5 core areas that need research investments and capacity development, particularly in LMIC: 1) improving injury data collection, 2) defining the epidemiology of unintentional injuries, 3) estimating the costs of injuries, 4) understanding public perceptions about injury causation, and 5) engaging with policy makers to improve injury prevention and control.

Local-level mortality surveillance in resource-limited settings: a case study of Cape Town highlights disparities in health. Bull World Health Organ 2010; 88:444-51. [PMID: 20539858 PMCID: PMC2878147 DOI: 10.2471/blt.09.069435] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2009] [Revised: 10/27/2009] [Accepted: 11/02/2009] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVE To identify the leading causes of mortality and premature mortality in Cape Town, South Africa, and its subdistricts, and to compare levels of mortality between subdistricts. METHODS Cape Town mortality data for the period 2001-2006 were analysed by age, cause of death and sex. Cause-of-death codes were aggregated into three main cause groups: (i) pre-transitional causes (e.g. communicable diseases, maternal causes, perinatal conditions and nutritional deficiencies), (ii) noncommunicable diseases and (iii) injuries. Premature mortality was calculated in years of life lost (YLLs). Population estimates for the Cape Town Metro district were used to calculate age-specific rates per 100,000 population, which were then age-standardized and compared across subdistricts. FINDINGS The pattern of mortality in Cape Town reflects the quadruple burden of disease observed in the national cause-of-death profile, with HIV/AIDS, other infectious diseases, injuries and noncommunicable diseases all accounting for a significant proportion of deaths. HIV/AIDS has replaced homicide as the leading cause of death. HIV/AIDS, homicide, tuberculosis and road traffic injuries accounted for 44% of all premature mortality. Khayelitsha, the poorest subdistrict, had the highest levels of mortality for all main cause groups. CONCLUSION Local mortality surveillance highlights the differential needs of the population of Cape Town and provides a wealth of data to inform planning and implementation of targeted interventions. Multisectoral interventions will be required to reduce the burden of disease.

Abstract
Background Extensive public health gains have benefited high-income countries in recent decades, however, citizens of low and middle-income countries (LMIC) have largely not enjoyed the same advancements. This is in part due to the fact that public health data - the foundation for public health advances - are rarely collected in many LMIC. Injury data are particularly scarce in many low-resource settings, despite the huge associated burden of morbidity and mortality. Advances in freely-accessible and easy-to-use information and communication (ICT) technology may provide the impetus for increased public health data collection in settings with limited financial and personnel resources. Methods and Results A pilot study was conducted at a hospital in Cape Town, South Africa to assess the utility and feasibility of using free (non-licensed), and easy-to-use Social Web and GeoWeb tools for injury surveillance in low-resource settings. Data entry, geocoding, data exploration, and data visualization were successfully conducted using these technologies, including Google Spreadsheet, Mapalist, BatchGeocode, and Google Earth. Conclusion This study examined the potential for Social Web and GeoWeb technologies to contribute to public health data collection and analysis in low-resource settings through an injury surveillance pilot study conducted in Cape Town, South Africa. The success of this study illustrates the great potential for these technologies to be leveraged for public health surveillance in resource-constrained environments, given their ease-of-use and low-cost, and the sharing and collaboration capabilities they afford. The possibilities and potential limitations of these technologies are discussed in relation to the study, and to the field of public health in general.

Abstract
BACKGROUND The utilisation and consequences of standardised operative procedures may importantly differ between different healthcare systems. This is the first investigation comparing the treatment and outcome of femoral shaft fractures stabilised with an identical implant between trauma centres in 2 continents (Europe, EU and South Africa, SA). METHODS Following standardised introduction of the technique, the prospective, observational multicentre study enrolled 175 patients who underwent intramedullary fracture fixation using the antegrade femoral nail (AFN) for femoral shaft fractures. Eleven EU hospitals recruited 86 patients and 1 SA centre 89 patients in the study period. Comparison of epidemiologic data, operative characteristics as well as subjective (e.g., pain, SF-36) and objective (e.g., X-ray, range of motion [ROM]) 3-month and 1-year outcomes were performed (p<0.05). RESULTS Compared to EU centres, several significant differences were observed in SA: (1) on average, patients operated on were younger, had less concomitant diseases and had more severe open fractures; (2) operative stabilisation was more often undertaken by young, unsupervised residents, with shorter operating and intraoperative fluoroscopy times; (3) mean hospital stay was shorter, with less recorded complications, but a higher loss to follow-up rate. Non- or malunion rates and subjective outcomes were similar for both groups, with the physical component of the SF-36 at the 1-year follow-up not fully restoring to baseline values. CONCLUSIONS Our investigation demonstrates the importance of several major differences between 2 different regions of the world in the treatment of femoral shaft fractures, despite involving only high level trauma centres and using an identical implant. The intercontinental comparison of results from clinical studies should be interpreted very carefully considering the heterogeneity of populations and clinical settings.

Abstract
Violence and injuries are the second leading cause of death and lost disability-adjusted life years in South Africa. The overall injury death rate of 157.8 per 100,000 population is nearly twice the global average, and the rate of homicide of women by intimate partners is six times the global average. With a focus on homicide, and violence against women and children, we review the magnitude, contexts of occurrence, and patterns of violence, and refer to traffic-related and other unintentional injuries. The social dynamics that support violence are widespread poverty, unemployment, and income inequality; patriarchal notions of masculinity that valourise toughness, risk-taking, and defence of honour; exposure to abuse in childhood and weak parenting; access to firearms; widespread alcohol misuse; and weaknesses in the mechanisms of law enforcement. Although there have been advances in development of services for victims of violence, innovation from non-governmental organisations, and evidence from research, there has been a conspicuous absence of government stewardship and leadership. Successful prevention of violence and injury is contingent on identification by the government of violence as a strategic priority and development of an intersectoral plan based on empirically driven programmes and policies.

Abstract
We explore the individual, organisational, familial, and community impacts of external workplace violence in a South African telecommunications company, as perceived and experienced by victims of such violence and the members of management mandated to manage and prevent it. Exposure to violence while working dramatically and directly affected the lives of the individual victims. Moreover, its impacts were felt across and within the organisational, familial, and community settings in which these individuals are located daily. The use of conventional crisis management strategies that are traditionally directed at addressing the individual impacts of trauma through specialised psychological interventions were perceived to be ineffective by all of the research participants. Our findings therefore call into question current understandings of the psychologist's role in managing violence in the workplace. Accordingly, ways of re-conceptualising the role and requisite skill set of psychologists working with or in organisations, where violence while working is an everyday reality, are suggested.

Abstract
BACKGROUND Injury patterns and interpretation of injuries in homicidal deaths are important components of medicolegal autopsies. The objective of this article is to describe the incidence of female homicides and their related injury patterns with reference to autopsy practices in South Africa. METHODS A national retrospective mortuary-based study of homicides in women of 14 years and older in 1999 was conducted. Data were gathered from medical legal laboratory records, autopsy reports, and police interviews from a stratified multistage sample of 25 mortuaries. RESULTS The most common cause of homicide was a gunshot wound injury, with a firearm mortality rate of 7.5/100,000 women, 14 years and older, in 1999, followed by sharp force injury (6.8/100,000) and blunt force injury (6.1/100,000). Gunshot victims were more likely to be African, and those killed by sharp force injury were more likely colored. Significantly, blunt force injury deaths occurred predominantly in intimate partner homicides. A full autopsy was performed only in 70% of cases. An assessment of postmortem reports revealed poor descriptions of the anatomic location of injuries and the specifications of wound dimensions. CONCLUSIONS South Africa has a high female homicide rate that exceeds reported rates with the cause of homicide varying by social group. Assessment of injury description suggests weaknesses in the documentation of injuries at autopsy. This weakens the forensic investigation and undermines the strength of evidence presented in court. Further measures are needed to strengthen forensic pathology services in South Africa.

Abstract
BACKGROUND A nationally representative study of psychiatric disorders in South Africa provided an opportunity to study the association between perpetration of human rights violations (HRVs) during apartheid and psychiatric disorder. Prior work has suggested an association between perpetration and post-traumatic stress disorder (PTSD), but this remains controversial. METHODS Subjects reported on their perpetration of human rights violations, purposeful injury, accidental injury and domestic violence. Lifetime and 12-month prevalence of DSM-IV (Diagnostic and Statistical Manual, 4th edition) disorders were assessed with Version 3.0 of the World Health Organization Composite International Diagnostic Interview (CIDI 3.0). Socio-demographic characteristics of these groups were calculated. Odds ratios for the association between the major categories of psychiatric disorders and perpetration were assessed. RESULTS HRV perpetrators were more likely to be male, black and more educated, while perpetrators of domestic violence (DV) were more likely to be female, older, married, less educated and with lower income. HRV perpetration was associated with lifetime and 12-month anxiety and substance use disorders, particularly PTSD. Purposeful and DV perpetration were associated with lifetime and 12-month history of all categories of disorders, whereas accidental perpetration was associated most strongly with mood disorders. CONCLUSION Socio-demographic profiles of perpetrators of HRV and DV in South Africa differ. While the causal relationship between perpetration and psychiatric disorders deserves further study, it is possible that some HRV and DV perpetrators were themselves once victims. The association between accidental perpetration and mood disorder also deserves further attention.

Abstract
BACKGROUND High levels of wealth inequality with improved health statistics in South Africa (SA) provide an important opportunity to investigate non-communicable diseases (NCDs) among the poor. AIMS This paper uses two distinct national data sets to contrast patterns of mortality in rich and poor areas and explore the associations between poverty, risk factors, health care and selected NCDs diseases in South African adults. METHODS Causes of premature mortality in 1996 experienced in the poorest magisterial districts are compared with those in the richest, using average household wealth to classify districts. Logistic and multinomial regression are used to investigate the association of a household asset index and selected chronic conditions, related risk factors and healthcare indicators using data from the 1998 South African Demographic and Health Survey. RESULTS NCDs accounted for 39% and 33% of premature mortality in rich and poor districts respectively. The household survey data showed that the risk factors hypertension and obesity increased with increasing wealth, while most of the lifestyle factors, such as light smoking, domestic exposure to ;;smoky'' fuels and alcohol dependence were associated with poverty. Treatment status for hypertension and asthma was worse for poor people than for rich people. CONCLUSIONS The study suggests that NCDs and lifestyle-related risk factors are prevalent among the poor in SA and treatment for chronic diseases is lacking for poor people. The observed increase in hypertension and obesity with wealth suggests that unless comprehensive health promotion strategies are implemented, there will be an unmanageable chronic disease epidemic with future socioeconomic development in SA.

Abstract
OBJECTIVE To examine the incidence and patterns of intimate femicide-suicide in South Africa and to describe the factors associated with an increase in the risk of suicide after intimate femicide (i.e. the killing of an intimate female partner). METHODS A cross-sectional retrospective national mortuary-based study was conducted at a proportionate random sample of 25 legal laboratories to identify all homicides committed in 1999 of women aged over 13 years. Data were collected from the mortuary file, autopsy report and a police interview. FINDINGS Among 1349 perpetrators of intimate femicide,19.4% committed suicide within a week of the murder. Suicide after intimate femicide was more likely if the perpetrator was from a white rather than an African racial background (odds ratio, OR: 5.8; 95% confidence interval, CI: 1.21-27.84); was employed as a professional or white-collar worker rather than a blue-collar worker (OR: 37.28; 95% CI: 5.82-238.93); and owned a legal gun rather than not owning a legal gun (OR: 45.26; 95% CI: 8.33-245.8). The attributable fraction shows that 91.5% of the deaths of legal gun-owning perpetrators and their victims may have been averted if this group of perpetrators did not own a legal gun. CONCLUSION South Africa has a rate of intimate femicide-suicide that exceeds reported rates for other countries. This study highlights the public health impact of legal gun ownership in cases of intimate femicide-suicide.
