Factors associated with Abnormalities of pulmonary function the bus driver.

Abstract

          The study of cross section in this study have objectives of studying the relation factors of anomaly efficiency lung of bus drivers who have risk of contact the pollution in Bangkok 38 samples. The statistic tools are descriptive statistic, mean, frequency, standard deviation, independent sample t- test, Chi square and multiple regression. The results showed that the bus drivers who contact small particulate matter (PM10) are in standard value of 3 mg/m3 (ACGIH). There are some bus driver contact higher than standard value. The value of particulate matter 1.06-4.75 mg/ m3 are in airbus and 1.25-3.19 mg/ m3 are in normal bus. The efficiency of lung are under normal standard value ( 85,72)% with FVC lower than standard (75,66.67%) and FEV1 under standard value ( 60,61.11%) respectively. However, comparing percentage of FEV1/FVC, it is in the normal standard range. The abnormally of lung efficiency demonstrated that the obstructive abnormal lung efficiency were 5- 5.6% and the abnormally of lung efficiency in expansion were 80, 66.7% respectively. Additionally, the abnormally mixed efficiency are 5% in air bus drivers. The study of relation factors showed that the significantly statistic relation factors were sex, weight, work experience, and smoking. The significant factors to predict lung efficiency were smoking, work experience, and PM10 showed result 60.72% at significant statistic 0.05. The factors which effect obstructive were weight and PM10 showed 23.5% at 0.05 significant statistical level. The factors which effect restrictive were PM 10, smoking and work experience showed result 64.8% at 0.05.
