Child pedestrian, drowning and burn mortality in Johannesburg.

The study examined the extent, demographics and risks for child pedestrian, burns and drowning mortality in Johannesburg. Information on the demographics, scene and temporal circumstances for childhood injury deaths from 2000 to 2010 was gleaned from the National Injury Mortality Surveillance System. Descriptive statistical methods were used. The study recorded 756 pedestrian (8.7/100,000), 439 drowning (5.1/100,000), and 399 burn injury deaths (4.6/100,000) among children aged 0-14 years. Male children were the main victims, with male-to-female ratios of 2.3 for drowning, 1.7 for pedestrian and 1.2 for burn mortality. The pattern of child mortality differed across age groups with older children recording higher rates for pedestrian deaths and younger children higher rates for the non-traffic deaths. Pedestrian and burn mortality especially affected black children, while drowning affected both black and white children. The time, day and month of greatest injury mortality varied by injury cause, with e.g. pedestrian mortality common in afternoons and evenings, weekends, and dispersed across the year although increasing towards year end. The study highlighted the salience of differentiating risks for childhood injuries by discrete external cause for purposes of informing prevention responses.

Fidelity of implementation of the building bridges mentoring intervention to prevent violence among youth in low income settings.

Violence among youth is a major health and safety burden globally. There is a dearth in the development and evaluation of targeted interventions that addresses the multi-faceted nature of youth violence to ensure effectiveness and replicability. This study aims to systematically evaluate the fidelity of implementation of the Building Bridges Mentoring intervention that focuses on the prevention of youth violence in two low-income communities in South Africa. This study employed a mixed methods concurrent triangulation design. Qualitative data were analysed using deductive thematic analysis, and quantitative data using descriptive statistics and T-tests. The results indicate that for all the intervention components, implementation fidelity (i.e. adherence, exposure, quality of programme delivery, and participant responsiveness) was generally moderate to high, suggesting a 'good' implementation of the programme in the real world. Evaluating the fidelity of implementation is vital to obtain a comprehensive insight into whether an intervention was implemented according to its design, and to verify and validate the findings and outcomes, and accord credibility and integrity of the study.

Neighbourhood characteristics associated with child pedestrian fatalities in Johannesburg, South Africa.

The present study investigated the relationship between neighbourhood characteristics and childhood pedestrian fatalities (2001-2010) in Johannesburg, South Africa. This cross-sectional study used negative binomial regression models. Results indicate that: areas with high concentrated disadvantage have elevated childhood pedestrian deaths, especially for those aged 5 to 9 years. Areas marked by residential mobility are associated with high pedestrian deaths among children 0 to 4 years. Black childhood pedestrian deaths are higher in areas marked by a high concentration of female-headed households. The analyses highlight the value of further exploring the effects of neighbourhood characteristics and suggest points of entry for interventions to reduce or prevent childhood pedestrian traffic mortality.

Evaluating the Effectiveness of Complex, Multi-component, Dynamic, Community-Based Injury Prevention Interventions: A Statistical Framework.

Dynamic violence and injury prevention interventions located within community settings raise evaluation challenges by virtue of their complex structure, focus, and aims. They try to address many risk factors simultaneously, are often overlapped in their implementation, and their implementation may be phased over time. This article proposes a statistical and analytic framework for evaluating the effectiveness of multilevel, multisystem, multi-component, community-driven, dynamic interventions. The proposed framework builds on meta regression methodology and recently proposed approaches for pooling results from multi-component intervention studies. The methodology is applied to the evaluation of the effectiveness of South African community-centered injury prevention and safety promotion interventions. The proposed framework allows for complex interventions to be disaggregated into their constituent parts in order to extract their specific effects. The potential utility of the framework is successfully illustrated using contact crime data from select police stations in Johannesburg. The proposed framework and statistical guidelines proved to be useful to study the effectiveness of complex, dynamic, community-based interventions as a whole and of their components. The framework may help researchers and policy makers to adopt and study a specific methodology for evaluating the effectiveness of complex intervention programs.

Community, intervention and provider support influences on implementation: reflections from a South African illustration of safety, peace and health promotion.

BACKGROUND: The development, implementation and evaluation of community interventions are important for reducing child violence and injuries in low- to middle-income contexts, with successful implementation critical to effective intervention outcomes. The assessment of implementation processes is required to identify the factors that influence effective implementation. This article draws on a child safety, peace and health initiative to examine key factors that enabled or hindered its implementation, in a context characterised by limited resources. METHODS: A case study approach was employed. The research team was made up of six researchers and intervention coordinators, who led the development and implementation of the Ukuphepha Child Study in South Africa, and who are also the authors of this article. The study used author observations, reflections and discussions of the factors perceived to influence the implementation of the intervention. The authors engaged in an in-depth and iterative dialogic process aimed at abstracting the experiences of the intervention, with a recursive cycle of reflection and dialogue. Data were analysed utilising inductive content analysis, and categorised using classification frameworks for understanding implementation. RESULTS: The study highlights key factors that enabled or hindered implementation. These included the community context and concomitant community engagement processes; intervention compatibility and adaptability issues; community service provider perceptions of intervention relevance and expectations; and the intervention support system, characterised by training and mentorship support. CONCLUSIONS: This evaluation illustrated the complexity of intervention implementation. The study approach sought to support intervention fidelity by fostering and maintaining community endorsement and support, a prerequisite for the unfolding implementation of the intervention.
