Analysis of Carbon Monoxide (CO) in Blood or Carboxyhemoglobin (COHb) on Psychological Stress in Public Transport Drivers (City Transportation) (Case Study in Depok in 2019)

Abstract

Carbon monoxide, in general, can cause hypoxia and lead to inflammation and stress. This study aims to
look at the relationship of carbon monoxide with stress on city transportation drivers. The study design used
a cross-sectional study. The sample in this study was 73 city transportation drivers who met the inclusion
criteria, a man, smoking, having health insurance and willing to draw blood. Research data were obtained by
interview for stress measurement and laboratory testing of blood samples to determine carboxyhemoglobin
levels. Data analysis uses simple linear regression for bivariate analysis. The results showed there was a
relationship between carboxyhemoglobin and stress (p-value = 0.003), the level of weak relationship was r
= 0.344. The line equation is obtained 0.118, that iscarboxyhemoglobin affects stress by 11.8%, while the
rest is influenced by other variables. Exposure to carbon monoxide increases carboxyhemoglobin levels so
that it can increase stress. It is hoped that public transport drivers can reduce smoking behavior and conduct
periodic testing of vehicle engines.
