Abstract
OBJECTIVES: The objective of this study was to measure the associations between domains of deprivation and antibiotic resistance of Escherichia coli. METHODS: Routine surveillance data for antibiotic susceptibility of E. coli isolates were obtained from urine specimens taken from patients presenting with suspected urinary tract infection in 2010-12 to healthcare practitioners based in the community in Leeds and Bradford. Eight antibiotics were included in the analyses. Postcodes were linked to lower super output areas (average populations of 1500). The 2010 Indices of Deprivation were used as neighbourhood characteristics for each lower super output area. Multilevel logistic regression models were used to estimate the independent effect of structural components on the odds of resistance to each antibiotic. RESULTS: With respect to living conditions, residence in the most-deprived areas compared with the least-deprived areas was associated with increased odds of antibiotic resistance for all eight antibiotics analysed. The magnitude of these associations included an OR of 2.04 (95% CI 1.03-3.07) for cefalexin, 2.16 (95% CI 1.16-4.05) for ciprofloxacin, 2.47 (95% CI 1.08-5.66) for nitrofurantoin and 1.33 (95% CI 1.07-1.75) for trimethoprim. CONCLUSIONS: Social deprivation in the form of living conditions is associated with increased antibiotic resistance for E. coli. This evidence suggests there is a need for further individual-level studies to explore the potential mechanism for these associations.
