  1. Urban Health and Disparities: A Comparison of 57 Cities *Email - cstauber@gsu.edu Christine Stauber*, Ellis Adams, Dajun Dai, Richard Rothenberg, John Heath

  2. Outline • Overview of the Urban Health Index • Toolkit and Methods • Description of data source • Selection of Indicators • Results • Ranking, comparison and correlation • Discussion and other applications

  3. The Urban Health Index Approach • We adopted a method used by the Human Development Index1to examine health disparities for small geographic areas. • We standardized indicators for small area units on a (0, 1) interval and combined them using their geometric mean to form an Urban Health Index (UHI).2 • The method uses the ratio of the highest and lowest deciles of the UHI and the linear slope of the middle 80% to assess disparities.

  6. Application of the UHI for cities • Selected publicly available datasets from the Demographic and Health Surveys – 2003-2013 – most recent dataset available • Identified set of 9 indicators from three domains – environment, women’s education and childhood immunizations • Identified major urban centers and selected data for 57 cities for calculation and comparison

  7. Nine indicators used for analysis Environment - • % of households with access to water piped onto premises • % of households with access to improved sanitation • % of households not using solid fuels Women’s Education - • % of women (15-49 y.o.) who completed secondary education or higher • % of women (15-49 y.o.) who believe that condom use decrease HIV risk • % of women (15-49 y.o.) that believe having only one partner can decrease HIV risk Health - • % of children (1-4 y.o.) who have received 3 doses of the DPT vaccine • % of children (1-4 y.o.) who have received 3 doses of the polio vaccine • % of children (1-4 y.o.) who have received the measles vaccine

  8. Results • Indicators oriented in positive direction so a higher UHI score indicates higher access to determinants of health • Tirana, Albania had the highest UHI score and therefore the highest rank • Port-Au Prince, Haiti and Monrovia, Liberia had the two lowest scores and were ranked the lowest • Regions presented a broad range of UHI scores with cities in Europe presenting on average the highest scores while cities in Sub-Saharan Africa presenting the lowest but broad variation existed within regions • UHI score appeared to be positively correlated with GNI but there were some important exceptions that deserve more attention

  9. Discussion • Cities in the African Region had the lowest UHI scores, followed by those in the Western Pacific and Southeast Asia, the Americas and the European Region. • Cities in the African Region may still be struggling to achieve coverage of the 9 indicators we examined. • As countries and their cities (principally their capital cities) develop economically, they begin to allocate more resources to improve coverage of service such as water and sanitation and access to health services and education as evident in our analysis of log-linear GNI and UHI scores. • However, there are important positive and negative deviations from this trend that deserve consideration.

  10. Conclusion • The UHI is a flexible measure that can examine a variety of direct indicators, social determinants, and demographic measures in conjunction with other data (e.g., GNI, Gini) and lends itself well to visualization. • A similar analysis for a sub-city level might be of greater value to identify “hot spots” and prioritize areas for remediation • When visualized in conjunction with measures of income or income disparity, the UHI identifies countries that: • Make better use of limited resources (high UHI with low GNI and Gini) • Maintain better resources yet whose problems in health and health disparities persist (low UHI with higher GNI and Gini) • Revisions in the cluster sampling methods used by DHS or similar surveys would provide much improved data sources for this type of city-level analysis, and especially for intra-city analysis
