在尼日利亚最北部北方，“麦苏亚”是一种常见的工作，那里有大量的木材烟雾和油烟。这些双重暴露对从事这项工作的工人的呼吸影响以前没有记录，因此进行了这项研究。目的是研究该人群的患病率、模式和呼吸功能评估。这是一项病例对照研究，研究对象是在职业环境中未暴露于木材烟雾和油烟的mai suya和工人。招募所有同意的mai suya和匹配的对照组。两组均进行现场肺功能测定，测量第一秒用力呼气量（FEV 1）、用力肺活量（FVC）、最大呼气流速（PEFR）。使用描述性统计量呈现结果。卡方被用来测试呼吸道症状和工作类别之间的关联。学生t检验用于比较连续变量的值。确定了呼吸道症状和接触木材烟雾和油烟的风险的比值。除了吸烟状况外，两组的人口统计学特征相似，因此目前的吸烟者被排除在进一步分析之外。试验组胸闷发生率显著增加：59%（19/32），鼻塞：37%（12/32），咳嗽：32%（10/32），喘息：与对照组相比为12%（4/32），比值比（OR）3.1，95%置信区间CI（0.1-5.8），P值0.04，OR 1.2，95% CI（1.04-1.8），P值= 0.02，OR 0.9，95% CI（0.9-1.4），P值= 0.3; OR 1.2，95% CI（1 ~ 1.3），P值= 0.04。一些呼吸道症状的发生与工作时间有关，而阳性哮喘家族史与症状发生率增加无关。试验组的平均（SD）FEV 1和FVC显著低于对照组; 2.5 L/s（0.55）vs 3.02 L/s（0.51），P值= 0.007; 2.7 L（0.7）vs 3.16 L（0.51），P值= 0.04。麦苏雅会增加呼吸道症状和肺功能改变的风险。需要防护设备和定期评估。
‘Mai suya’ is a common job in the most northern Nigeria in which there is significant exposures to wood smoke and oil fumes. The respiratory impact of these dual exposures on workers engaged in this work has not been previously documented, hence this study was carried out. The aim is to study the prevalence, patterns and respiratory function assessment among this group. This is a case controlled study involving mai suya and workers who are not exposed to wood smoke and oil fumes in an occupational setting. All consenting mai suya and matched controls were recruited. Both groups underwent an interviewer administered questionnaire followed by on spot spirometric test measuring forced expiratory volume in one second (FEV1), forced vital capacity (FVC), peak expiratory flow rate (PEFR). Results are presented using descriptive statistics. Chi square was used to test for association between respiratory symptoms and the job categories. Student's t-test was used to compare values of continuous variables. Odd ratios were determined for the risk of respiratory symptoms and exposure to wood smoke and oil fumes. Both groups are similar in their demographic characters except in their smoking status, so current smokers were excluded from further analysis. The test group had significantly increased occurrence of chest tightness: 59% (19/32), nasal congestion: 37% (12/32), cough: 32% (10/32), and wheeze: 12% (4/32) compared with the control group, odds ratio (OR) 3.1, 95% confidence interval CI (0.1-5.8), P value 0.04, OR 1.2,95% CI (1.04-1.8), P value = 0.02, OR 0.9 95% CI (0.9-1.4), P value = 0.3, and OR 1.2,95% CI (1-1.3), P value = 0.04, respectively. Occurrences of some respiratory symptoms were associated with duration on the job, while a positive family history of asthma is not associated with increased occurrence of symptoms. The mean (SD) FEV1 and FVC were significantly lower among the test group compared with the control group; 2.5L/s (0.55) versus 3.02L/s (0.51), P value = 0.007 and 2.7L (0.7) versus 3.16L (0.51), P value = 0.04. Mai suya’ have increased risk of respiratory symptoms and altered pulmonary functions. There is a need for protective equipment and periodic evaluation.
