ABSTRACT: This study explores spatio-temporal trends in adverse birth outcomes (ABO) in the state of Massachusetts from 2000-2014. ABO includes low birth weight (< 2500 g) and preterm birth (gestational age <= 37 weeks). This research evaluates if there are areas in Massachusetts that have experienced statistically significant increases or decreases in ABOs throughout the study period. Birth data was obtained from the Massachusetts Department of Public Health and only singleton live, black births were selected for the analysis. The data were aggregated to census tracts, and the total number of births and the number of ABOs were calculated for each census tract for each year. In total, 1469 census tracts were included in this analysis. A Space-time cube of ABO rates was created in ArcGIS software, with a time step of one year and 200m x 200m spatial bins. Temporal trends in ABO rates were assessed using the Mann-Kendall statistics. The Mann-Kendall test shows statistically significant upward trends in 66 census tracts (increase in ABO rates over time) and significant downward trends (decrease in ABO rates over time) in 56 census tracts. These tracts are randomly distributed throughout the state and do not form apparent spatial clusters. It is apparent that a majority of the study area did not show any statistically significant trend over time, but the areas that showed statistically significant trends need to be further evaluated in order to potentially initiate public health interventions and awareness.
