DISTRIBUSI SPASIAL DAN FAKTOR RISIKO DIFTERI DI KOTA MALANG PROPINSI JAWA TIMUR

Background: is an acute infectious disease caused by the bacteria Corynebacterium diphtheriae. Cases of diphtheria in the city of Malang is likely to increase from year to year. There were 18 cases in 2009 with 0 deaths, in 2010 a total of 39 cases with 1 death and increased significantly in 2011 as many as 65 cases with 0 death. In 2011, Malang was the highest in the case of East Java after Surabaya City. Objective : Knowing spatial distribution of diphtheria and to identify risk factor of diphtheria at Malang City, Province of East Java. Methods: Analytic observational study is a case-control design. Samples were taken with a consecutive sampling technique with the number of each case and control samples of 90 individuals. Data analysis using the Mc. Nemar and Conditional logistic regression. Dependent variable was the incidence of diphtheria, while the independent variable is the immunization status, occupancy density, distance to health facilities, place the activity and mobility. Results: The pattern of distribution of diphtheria in Malang City are clustered at coordinate 6675248, 912 050 UTM Zone 49S, radius 3621.03 meters. Risk factors for diphtheria in Malang City is place the activity p = 0.003 (OR = 5.4 and 95% CI 1.802 to 16.492) and mobility p = 0.003 (OR = 3.5 and 95% CI 1.558 to 8.152). Conclusion: The place of activity is the most dominant risk factor in the incidence of diphtheria in Malang City after control of the impact of variable mobility
