Purpose: The purpose of this study was to explain the extent to which critical values of FVC and FEV1 were able to predict risk factors for severity of airway obstruction in bus terminal Officers in Solo Raya Indonesia.
Method: This study used a descriptive survey design with a cross-sectional approach. The sample of this study was the bus terminal Officers in Solo Raya Indonesia who work in the field of traffic, vehicle inspection, and parking. The sample consisted of 139 random respondents. The severity of airway obstruction was measured through critical values of FVC and FEV1 using Spirometry. The research data analysis technique used the Logistic Regression Test with a significance level of 95%.
Result: The results of this study showed that the prevalence of sex for the majority of men was 64.7%, the age group 43-50 years was 30.9%, the years of service of 21-30 years was 38.8%, and the severity of obstruction of the airway was mostly in the light category of 52.5 %. The measurement model for critical values of FVC and FEV1 was able to predict the significant severity of obstruction of airway by 80.7% and the traffic officers were at higher risk of obstructing airway significantly by 3.88 times compared to those working in parking, or vehicle inspection as indicated by ρ = 0.008 <0.05; at least, the traffic officers had 1,420 to 10,637 times higher to get airway obstruction.
Conclusion: Officers who serve in the field of traffic work have a tendency to be exposed to exhaust emissions of motorized vehicles on the highway, so there is a risk of an increase in the severity of road obstruction compared to those in other occupations. For this reason, the need for early detection through routine inspection and increasing the capacity of traffic Officers and road transport in an effort to prevent the severity of airway obstruction through the movement of work safety discipline using masks. This is important because of the risk of exposure to exhaust gas emission air pollution on the highway.
