【摘要】 目的 :比较固硫型煤与普通煤对人体鼻咽部健康的影响。方法 :采用现场干预试验 ,实验组给予固硫型煤 ,对照组仍用普通煤 ,追踪观察 10个月。结果 :实验组与对照组实验前后在性别、年龄构成上均衡 ;χ2检验、logistic回归分析、典型相关分析均显示实验组人群鼻咽部患病有显著降低。结论 :使用固硫型煤相对与普通煤能够显著降低人群鼻咽部的患病 ,建议推广固硫型煤。更多还原

【Abstract】 Objective:To Compare the influence of combusting bio-briquette on nasopharynx with burning raw coal.Methods:To use population intervention study,the experiment group provided for bio-briquette and the control group for raw coal,which be observed for 10 months.Results:The proportion between the two groups is equilibrium. And the Chi-square test?Logistic regression?Canonical correlation show that the bio-briquette group has significantly less prevalence rate on nasopharynx than that of raw coal.Conclusion:Combusting bio-briquette is a protective factor for peoples nasopharynx to burning raw coal.Bio-briquette should be used instead of raw coal.更多还原
