Carboxyhemoglobin levels in blood donors in Bahrain
1Arabian Gulf University, Bahrain.
Insights
Smoking significantly elevates carboxyhemoglobin (COHb) levels in Bahraini blood donors. Outdoor workers also showed higher COHb, suggesting environmental carbon monoxide exposure impacts blood COHb concentrations.
Area of Science:
- Environmental Health
- Occupational Health
- Toxicology
Background:
- Carboxyhemoglobin (COHb) is a biomarker of carbon monoxide exposure.
- Understanding COHb levels in a population is crucial for assessing environmental and occupational health risks.
Purpose of the Study:
- To investigate the factors influencing carboxyhemoglobin levels in blood donors in Bahrain.
- To determine the impact of smoking, occupation, and work environment on COHb concentrations.
Main Methods:
- Analysis of 107 venous blood samples from Bahraini blood donors.
- Categorization of donors based on sex, smoking habits, occupation, work environment (indoor/outdoor), and residential area.
- Statistical comparison of mean COHb levels across different donor groups.
Main Results:
- Mean COHb levels were significantly higher in smokers (4.8%) compared to nonsmokers (1.5%).
- Outdoor workers, both smokers (4.98%) and nonsmokers (2.29%), exhibited higher COHb than indoor workers (3.07% and 1.04%, respectively).
- Sex and residential area did not show a significant influence on COHb concentrations.
Conclusions:
- Smoking is a primary determinant of elevated COHb levels in the Bahraini population.
- Environmental carbon monoxide exposure, potentially from outdoor work environments, may contribute to higher COHb levels.
- Further research is warranted to explore the link between environmental carbon monoxide and blood COHb in Bahrain.
Abstract:
A total of 107 venous blood samples were obtained from blood donors in Bahrain for carboxyhemoglobin (COHb) analysis. The donors were categorized according to their sex, smoking habits, occupation, place of work (indoor or outdoor), and residential area. The mean COHb levels were significantly higher in smokers (4.8%) than nonsmoking (1.5%). The mean COHb levels were higher in smoking, outdoor working donors (4.98%) and nonsmoking outdoor working donors (2.29%) than smoking indoor working donors (3.07%) and nonsmoking indoor working donors (1.04%). Other factors, such as sex and residential area did not influence COHb concentrations. The results indicate a possible influence of the levels of environmental carbon monoxide on the COHb in the blood of the Bahraini population.
