摘要

背景和目的:本研究的目的是在一项时间序列研究中评估在智利中南部六个被木材烟雾严重污染的城市中暴露于颗粒物质2.5对呼吸道急诊就诊的短期影响。方法:使用限制在7天滞后期的分布滞后线性和非线性泊松模型来评估相关性,调整时间趋势和气象变量,并按季节分层为冷期和暖期。结果表明:寒期颗粒物-2.5的日平均浓度是暖期的3 ~ 6倍,超过50µg/m3日平均值的时间分别为93.3%和6.7%。与温暖季节相比,寒冷季节的平均每日呼吸道急诊次数高出30%至64%。从线性模型来看,每10 mg/m3细颗粒物增加0-7天的累积相对风险比在1.004(95%置信区间:0.998 ~ 1.010)~ 1.061(95%置信区间:1.049 ~ 1.074)之间;这些年效应可归因于冷期的影响,其中累积风险比在1.008(95%置信区间:1.004 - 1.012)和1.036(95%置信区间:1.026 - 1.047)之间,因为在暖期未发现细颗粒物对所研究风险的显著影响。结论:通过非线性模型,我们观察到在整个时期内,与颗粒水平有很强的增加关系。来自柴火的高水平细颗粒物与接触数天后可观察到的呼吸效应有关。本研究发现的健康影响表明,当前旨在减轻柴烟相关排放的政策应继续并加强。

The effect of short-term of fine particles on daily respiratory emergency in cities contaminated with wood smoke
BACKGROUND AND OBJECTIVES: The goal of this study is to evaluate in a time-series study the short-term effects of particulate matter-2.5exposure on respiratory emergency visits in six central-southern Chilean cities highly contaminated by wood smoke. METHODS: Association was assessed using both distributed lag linear and non-linear Poisson models constrained to a 7-day lag period, adjusting for temporal trends and meteorological variables and stratifying seasonally into cold and warm periods. FINDING: The results showed that the daily average concentrations of particulate matter-2.5in the cold period were 3 to 6 times those recorded in the warm period, exceeding the daily norm of 50 µg/m3 the 93.3% of the time versus 6.7%, respectively. The average daily number of respiratory emergency visits were between 30% and 64% higher in the cold period compared to the warm one. From linear models, cumulative relative risk ratios over 0-7 day lags per 10 mg/m3 of fine particle increase were between 1.004 (95% confidence Interval: 0.998 - 1.010) and 1.061 (95% confidence Interval: 1.049 - 1.074); these annual effects are attributable to the cold period impact where the cumulative risk ratios  were between 1.008 (95% confidence Interval: 1.004 - 1.012) and 1.036 (95% confidence Interval: 1.026 - 1.047), since significant effects of fine particles on the studied risk were not found for the warm period. CONCLUSION: With non-linear models we observed strong increasing associations with the level of particles for the overall period. High levels of fineparticles from firewood are associated with respiratory effects observable several days after exposure. Health effects found in this study suggest that current policies tending to mitigate woodsmoke-related emissions should continue and reinforce.
