Assessment of Under-5 Mortality Rates in İstanbul Using the Geographic Information System

Abstract

Objective: Analyzing mortality rates and the reasons for these in Turkey's urban allocations using geographic information systems (GISs) is a new research area. While planning health services, knowing the mortality rates and reasons according to age and residential area are a big source of information for health planners and people who provide health services. The aim of this research is to analyze the deaths of children under the age of 5 years in big cities depending on a socioeconomic range using GIS. Further, this should make it possible to determine geographically risky places. Materials and Methods:The deaths of children under the age of 5 years that occurred between 2005 and 2009 were analyzed. Date from the Turkish Statistical Institute (Turk Stat) concerning population and age-specified deaths, İstanbul Metropolitan Municipality (IMM) cemetery directorate death records, and the Ministry of Finance land unit prices (to determine the socioeconomic level of the districts) were used as data resources. The Z value of each year's death rate, depending on the districts age ranges and average of all years' Z values, was calculated and is shown on the map.

Infant mortality in Turkey: Causes and effects in a regional context

“…First, although exceptionally high infant mortality rates and persistent regional variations in Turkey are known, the implications of spatial patterns remain largely unknown due to the unavailability of fine‐scale georeferenced data. Only a scant number of studies in Turkey visualized the spatial patterns in the assessment of local socioeconomic and environmental factors and the resulting disparities in infant mortality rates using geographic information system (GIS) analysis (Arslan, Cepni, & Etiler, 2013; Babaoğlu, Işsever, & Hapçıoğlu, 2016) and other spatial tools (Karahasan & Bilgel, 2019). While the GIS analysis of Arslan et al (2013) suggests a link between poor environmental conditions and perinatal mortality in the heavily industrialized province of Kocaeli in the Marmara region, the province‐level spatial analysis of Karahasan and Bilgel (2019) suggests an increasing geographic polarization in infant and child mortality rates and a non‐robust link between healthcare access or utilization, and child mortality in the already‐developed regions of Turkey.…”

Evaluation of Drug Overdose Suicide Attempts Using GIS in İstanbul: A 3-Year Retrospective Study

“…Yirmi üç bin yedi yüz bir olgunun yer aldığı çalışmada, Avrupa yakasında, Anadolu yakasına oranla daha fazla çocuk ölümlerinin gerçekleştiği bildirilmektedir. 18 Diğer taraftan, yasa dışı madde kullanımı da gerek halk sağlığını gerekse adli otoriteleri ilgilendiren önemli bir konudur. 1998-2005 yılları arasında Türkiye'de Ağır Ceza Mahkemesinde işlem gören dosyalardan elde edilen verilerin CBS aracılığı ile değerlendirilmiş olduğu görülmektedir.…”
