Purpose: The effects of social determinants on populations health is well known. However, there is little scientific evidence that urban upgrading interventions help improve health or reduce inequities. This study aimed to assess the impact of urban interventions of the Viva Villa Project on the health of people living in slums, evaluating the mortality rates by homicides in areas with and without interventions.
Methods: This is a quasi-experimental study using mortality data from a special designed data warehouse. Since 2002, in Belo Horizonte municipality, community-based participatory and structural urban interventions of slum areas has been developed. These interventions involve implementation and improvement of the roadway system, water supply and sewage networks and housing improvements.. Annual mortality rates by homicides were compared between slums with intervention (SI) with slums without intervention (SW), according to the schedule of interventions. Univariate linear regressions were carried out by comparing the case and control slums and the pre and post work periods. Significance level of 5% and confidence intervals of 95% were considered for all analysis.
Results: Investigating the mortality rate from homicide in the pre and post intervention periods we observed that in the slums with interventions there was a statistically significant decrease in the post-work period, unlike what occurred in the post-work period in the slums that did not undergo intervention. In the pre-work period the falls in mortality rates were not significant in both case and control slums.
Conclusion: The results point to a possible effect of interventions on homicide mortality rates in the post-work period, comparing case and control slums grouped. These are preliminary analyzes and further investigations should be carried out considering each pair of slums case and control as well as the time of exposure of the intervention and the time of exposure of the benefit after its completion.
