There is a surge increase in grills-fast food outlet in the urban areas that plays an essential role in producing air pollution. Chronic accumulation of carbon monoxide might affect the airway and destroy alveolus as well as correlated with the disturbance of lung function.
The purpose of this study is to compare the occupational CO levels, HbCO, and lung functions between grill and non-grill street vendors.
This was an observational analytic study with a case-control design. The subjects were grill street vendors and non-grill street vendors in Medan city who fulfilled several inclusion criteria. The questionnaire was used to determine some characteristics, while smokerlyzer, and ELISA for expiration CO level and blood CO level, spirometer was used to determining lung function. Logistic regression was performed with p-value < 0.05 considered to be significant using SPSS ver 24.0.
A total of 50 subjects enrolled into this study with the majority of subjects in the case group were in red (40%) zone in CO exhaled test with the results in pulmonary function test, predominantly restrictive (56%) and mixed-type (40%) with the mean value of HbCO was 486.16 (ng/mL). Meanwhile, the majority of subjects were green zone with mixed type of lung function disturbance in the control group with 540.15 (ng/mL) as HBCO mean value. Grilled street vendors have a higher level of exhaled CO level (p- value: 0.03) without significant difference in HbCO and lung functions (p-value > 0.05). Age, smoking status, HbCO, and lung function did not significantly affect the CO level (p-value: 0.05).
There was a significant difference in exhaled CO level between grill-and non-grill street vendors without significant difference in HbCO and lung functions.
城市中烤架快餐店的数量激增，它们在产生空气污染方面起着至关重要的作用。慢性一氧化碳积累可能会影响气道并破坏肺泡，并与肺功能障碍有关。
本研究旨在比较烧烤和非烧烤街头小贩的职业 CO 水平、HbCO 和肺功能。
这是一项观察性分析研究，采用病例对照设计。研究对象为在棉兰市符合多项纳入标准的烧烤和非烧烤街头小贩。问卷调查用于确定一些特征，而吸烟者和酶联免疫吸附试验用于确定呼气 CO 水平和血 CO 水平，肺量计用于确定肺功能。使用 SPSS 版本 24.0 进行逻辑回归分析，p 值<0.05 被认为具有统计学意义。
共有 50 名受试者纳入本研究，其中大多数病例组的受试者在呼气 CO 测试中处于红色（40%）区域，肺功能测试结果主要为限制性（56%）和混合性（40%），HbCO 的平均值为 486.16（ng/mL）。另一方面，对照组中大多数受试者处于绿色区域，肺功能障碍为混合类型，HbCO 的平均值为 540.15（ng/mL）。烧烤街头小贩的呼气 CO 水平较高（p 值：0.03），但 HbCO 和肺功能无显著差异（p 值>0.05）。年龄、吸烟状况、HbCO 和肺功能对 CO 水平没有显著影响（p 值：0.05）。
烧烤和非烧烤街头小贩之间的呼气 CO 水平存在显著差异，但 HbCO 和肺功能无显著差异。
