Key result
Sheesha smoking was associated with significantly higher mean carboxyhaemoglobin levels compared to cigarette smoking (8.8 vs 6.1; P<0.001).
Why the study?
Does sheesha smoking result in higher carboxyhaemoglobin levels compared to cigarette smoking?
Cross-Sectional
Does sheesha smoking result in higher carboxyhaemoglobin levels compared to cigarette smoking?
Absolute Event Rate: 8.8% vs 6.1%
p-value: p=<0.001
Sheesha smoking is associated with significantly higher carboxyhaemoglobin levels than cigarette smoking for a given degree of tobacco exposure.
Sheesha may confer greater CO exposure than cigarettes; leaves open whether this elevates cardiovascular risk, warranting prospective study.
A single carboxyhaemoglobin (COHb) estimation of late evening blood sample among non-smokers, cigarette smokers, and sheesha smokers was evaluated among Saudis. The COHb level in smokers of 15 to 40 cigarettes a day ranged between 0.7 and 10.3 with a mean value of 6.1 +/- 2.58 COHb. Values among sheesha smokers ranged between 6.5 and 13.9 with a mean value of 8.8 +/- 1.83, significantly higher than those of cigarette smokers (P less than 0.001) for a given degree of exposure to tobacco smoke.

Zahran et al. (1982) conducted a cross-sectional in Smoking. Sheesha smoking vs. Cigarette smoking was evaluated on Carboxyhaemoglobin (COHb) level (p=<0.001). Sheesha smoking was associated with significantly higher mean carboxyhaemoglobin levels compared to cigarette smoking (8.8 vs 6.1; P<0.001).
