Association Between Outcomes and Demographic Factors in an Azeri Turkish Population With Cystic Fibrosis: A Cross-Sectional Study in Iran From 20 01 Through 2014
چکیده
Background: Outcomesforcystic fibrosis patients are improving rapidly. The demographic factors are notable variables inoutcomes, which can be evaluated and modified. Objectives: This study was designed to investigate the association between outcome and demographic factors in patients with cystic fibrosis. Patients and Methods: This was a cross-sectional study and data were gathered for 331 patients using the census method, from March 20 01 to September 2014 in Iran. Data was analyzed using logistic regression analysis, chi-square test, and independent sample t test using SPSS18. Odds ratio with confidence intervals of 95% and P<0.05 were considered significant. Results: There were 85 (25.7%) deceased patients and 246 (74.3%) living patients at the time of the study. Of the 246 living CF patients, 202 (82.2%) were less than nine years of age, and 77 (90.6%) out of the 85 deceased CF patients had died younger than four years of age. There was a significant difference between outcome and location of residence. The risk of mortality was 50% less in urban patients than in rural patients (P=0.03).The risk of mortality was approximately two times higher in patients with a positive family history than in those with a negative family history (P=0.02).The proportion of mortality was approximately two times, or 94%, higher for those in a consanguineous marriage than for those in a non-consanguineous marriage (P=0.01). Conclusions: The results demonstrated that the mortality rate was higher in CF patients with a positive family history, a consanguineous marriage, and residence in a rural area. Therefore, demographic factors play an important role in the outcome of cystic fibrosis. Unfortunately, these parameters, which can be managed easily and with low cost, have been overlooked.
