to analyze association between environmental variables and leptospirosis incidence in the municipality of Rio Branco, Acre, Brazil, 2008-2013.
this was an ecological study of association between monthly average environmental variables and monthly leptospirosis incidence, according to generalized autoregressive score models and moving averages.
increases in the monthly average levels of the River Acre and days of precipitation per month were associated with a 7% increase (incidence rate ratio [RR] 1.07 - 95%CI 1.02;1.14) and a 4% increase (RR 1.04 - 95%CI 1,00;1,07) in the monthly incidence of leptospirosis, respectively; in 2013 leptospirosis incidence in the municipality was 8 times higher than in 2008 (RR 8.00 - 95%CI 4.07;15.71).
this study showed a strong increase in leptospirosis incidence, over the years studied, and positive associations with environmental variables.
分析2008 - 2013年巴西阿克里州里奥布兰科市环境变量与钩端螺旋体病发病率之间的关联。
这是一项基于广义自回归评分模型和移动平均值的生态研究，分析每月平均环境变量与每月钩端螺旋体病发病率之间的关联。
阿克里河月平均水位升高和每月降水天数增加分别与钩端螺旋体病月发病率增加7%（发病率比[RR] 1.07 - 95%置信区间1.02；1.14）和4%（RR 1.04 - 95%置信区间1.00；1.07）相关；2013年该市钩端螺旋体病发病率比2008年高8倍（RR 8.00 - 95%置信区间4.07；15.71）。
本研究表明，在所研究的年份中，钩端螺旋体病发病率大幅上升，且与环境变量呈正相关。
