背景：天气与食源性疾病的关系近年来备受关注。然而，天气变化对食源性疾病的影响可能因不同地区的地理、天气和人口特征而有所不同。这项研究的目的是量化天气变量和弯曲杆菌感染之间的关系，在澳大利亚的两个城市与不同的当地气候条件。利用1990-2005年期间每周疾病监测数据和气象数据进行了一项生态-流行病学研究，以量化最高和最低温度、降雨量、相对湿度和弯曲杆菌感染的通知阿德莱德，具有温带地中海气候，和布里斯班，具有亚热带气候。斯皮尔曼相关性和时间序列调整泊松回归分析进行考虑到季节性，标签效应和长期trends.Results：结果表明，每周最高和最低温度呈负相关，每周病例数在阿德莱德，但正相关的病例数在布里斯班，与相关的标签效应。结论：不同城市的天气对细菌感染的影响可能存在差异。需要进一步的研究来更好地了解这些关系，因为它们可能表明流行病学因素对控制这些感染很重要。(C)2008年，英国传染病协会。由爱思唯尔有限公司出版。保留所有权利。
Background: The relationship between weather and food-borne diseases has been of great concern recently. However, the impact of weather variations on food-borne disease may vary in different areas with various geographic, weather and demographic characteristics. This study was designed to quantify the relationship between weather variables and Campylobacter infections in two Australian cities with different local climatic conditions.Methods: An ecological-epidemiological study was conducted, using weekly disease surveillance data and meteorological data, over the period 1990-2005, to quantify the relationship between maximum and minimum temperatures, rainfall, relative humidity and notifications of Campylobacter infections in Adelaide, with a temperate Mediterranean climate, and Brisbane, with a sub-tropical climate. Spearman correlation and time-series adjusted Poisson regression analyses were performed taking into account seasonality, tag effects and long-term trends.Results: The results indicate that weekly maximum and minimum temperatures were inversely associated with the weekly number of cases in Adelaide, but positively correlated with the number of cases in Brisbane, with relevant tagged effects. The effects of rainfall and relative humidity on Compylobacter infection rates varied in the two cities.Conclusion: Weather might have different effect on Compylobacter infections in different cities. Further studies are needed for a better understanding of these relationships for they may indicate epidemiologic factors important for control of these infections.
