摘要:

目的 对朝阳市1999-2009年肾综合征出血热(HFRS)发病趋势与流行因素进行分析,探讨其是否存在因果关系,为进一步掌握朝阳市HFRS的流行规律、指导防制提供可供借鉴的依据。方法 将1999-2009年朝阳市HFRS发病资料分别按年龄、性别、职业、季节、年降雨量、朝阳市主要农产品高粱、玉米、谷子的年产量进行归类和运用统计软件进行相关分析。结果 朝阳市10年来HFRS流行特点,年龄分布男性占发病总数的75.48%(782/1036),20~50岁年龄组人群占发病总数的79.92%(828/1036),农民发病构成比为71.72%(743/1036),揭示出朝阳市HFRS发病以男性、20~50岁年龄组、农民为高发人群;春季为高发季节;生境因素中年降雨量的变化对HFRS疫情的波动影响不大(r=0.182,P=0.593);生物因素中HFRS发病趋势与谷子年产量相关(r=0.694,P=0.018),与高粱(r=0.475,P=0.140)、玉米(r=0.481,P=0.134)年产量不相关。结论 朝阳市HFRS疫情的三间分布符合家鼠型HFRS的流行病学特征;谷子年产量与HFRS疫情波动呈正相关,与高粱、玉米年产量不相关;为做好HFRS的防控工作提供启示。

Abstract:

Objective To analyze prevalence trends and epidemiological factors of hemorrhagic fever with renal syndrome (HFRS) in Chaoyang city from 1999 to 2009, in order to clarify causal correlations, better understand the epidemiology of the disease and improve prevention and control measures. Methods Statistical analyses were performed based on the HFRS data stratified by age, sex, occupation, season, annual rainfall amount, and annual output of major agricultural products (sorghum, corn and millet) in Chaoyang from 1999 to 2009. Results During the past decade, male patients accounted for 75.48% (782/1036) of the total number of HFRS patients; patients aged 20 to 50 years accounted for 79.92% (828/1036) and farmers accounted for 71.72% (743/1036). These Results indicate that males, aged 20 to 50 years old, and farmers were the highest risk population. Futher, spring was the peak season of transmission. As for environmental factors, changes in the annual rainfall amount did not affect the prevalence of HFRS (r=0.182, P=0.593). However, the annual millet output was correlated with the incidence (r=0.694, P=0.018) rather than sorghum (r=0.475, P=0.140) or corn (r=0.481, P=0.134). Conclusion The spatial, temporal and population distribution of HFRS was consistent with epidemiological characteristics of the disease. The annual millet output was positively correlated with HFRS incidence. These Results can inform prevention and control programs for HFRS.
