Abstract:
Objective To describe the spatiotemporal patterns of genital chlamydia trachomatis(GCT)infections in Guangdong,and to explore social-economic factors associated with the risk of GCT infections.Methods Data of GCT infections among women of childbearing age in Guangdong province from 2014 to 2019 and social-economic factors were collected.Bayesian spatiotemporal hierarchy model with Poisson distribution was established including temporal and spatial terms.Integrate nested Laplace approximates(INLA)was used to estimate the parameters.Results GCT infections among women of childbearing age in Guangdong had no obviously temporal effect,but had significantly spatial heterogeneity.After adjusting for fixed covariate effects and temporal random effect,high-risk regions concentrated in Pearl Delta region.Comprehensive economic development(RR=1.185,95%CI:1.117～1.257)and population and transportation level(RR=1.058,95%CI:1.012～1.106)were positively associated with the prevalence of GCT infections,while the health service level had negatively association(RR=0.942,95%CI:0.924～0.960).Conclusion The prevalence of GCT infections among women of childbearing age shows spatial clustering characteristics.Social-economic factors are significantly related to the prevalence of GCT infections.
