Abstract
RODRIGUEZ-VILLAMIZAR, Laura Andrea et al. Cluster analysis of childhood cancer and its relationship with proximity to sources of industrial pollution in the Valle de Aburrá Metropolitan Area, 2000-2015. Rev. Fac. Nac. Salud Pública [online]. 2022, vol.40, n.2, e04. Epub May 30, 2023. ISSN 0120-386X. https://doi.org/10.17533/udea.rfnsp.e346065.
Objective:
This study evaluated the effect of proximity to industrial sources of air pollution on the occurrence of clusters of childhood cancer cases in the Aburrá Valley Metropolitan Area, Department of Antioquia, during the 2000-2015 period.
Methodology:
The information on childhood cancer cases in children under 15 years of age residing in the metropolitan area was obtained from the Registro Poblacional de Cáncer de Antioquia (Antioquia Cancer Population Registry) for that period. 32 industrial clusters were identified based on the local environmental authority's inventory. Local and targeted Kulldorff's circular scan tests were performed to detect childhood cancer clusters in the municipalities and surrounding the industrial clusters, respectively. We used a multivariate regression model adjusted for socioeconomic strata to assess the effect of spatial variables.
Results:
The specific incidence rate in the Aburrá Valley for the evaluated period was 117.13 cases per million children under 15 years of age. The highest incidence rates occurred in the municipalities of Medellín and Sabaneta. The Kulldorff test identified 12 spatial clusters and 8 space-time clusters that were statistically significant in 7 municipalities, particularly in Bello and Medellín. The targeted tests identified childhood cancer clusters surrounding 20 industrial clusters. In multivariate models, an industrial cluster in Bello showed a statistically significant inverse association between incidence and distance from the industrial cluster toward the southeast.
Conclusion:
Some space-time childhood cancer clusters in the Aburrá Valley Metropolitan Area between 2000 and 2015 are related to proximity to industrial sources of air pollution.
