A pilot study was conducted to determine whether any relationship exists
between micronucleated cell rates of female uterine cervical epithelium and
current smoking status. Cervical uterine cells obtained from 118
pre-menopausal females, seen between September 1994 and June 1995 at the
Occupational Medecine Interprofessional Association (AIMT), were tested for
micronucleated cells by the micronucleus assay. Of the 68 subjects taken
from this population that provided a least a 1000 analysed cells, 36 were
non-smokers and 32 were smokers. Age distributions were different between
smokers and non-smokers but results showed that age had no effect on
micronucleated cell levels. Micronucleated cervical cell rates reached
0.66% in non-smokers and 1.11% in smokers: these two levels were not
statistically different. No association was noted between number of
cigarettes smoked and micronucleated cell levels. Results suggested that
consuming 5-20 cigarettes per day was not enough to show a smoking effect
on cervical micronucleated cells. A test with a greater number of female
subjects would be necessary to confirm this.
