Objective:
We sought to evaluate the association between passive cigarette smoke exposure and cervical cytological abnormalities in a predominantly Hispanic sample.
Study Design:
Data were collected as part of a larger, ongoing randomized clinical trial. Inclusion criteria were met by 4403 Hispanic (73%) and non-Hispanic (27%) women between 18-55 years of age (mean = 30.14 ± 8.7). Analysis of variance and multivariate logistic regression determined the association between passive smoke exposure and Pap abnormality.
Results:
Passive smoke exposure was positively associated with having an abnormal Pap smear (odds ratio, 1.70; 95% confidence interval, 1.14-2.52) as was current active smoking (odds ratio 1.45; 95% confidence interval, 1.03-2.04). Neither effect was modified by ethnicity. Increasing hours per week of passive smoke exposure was associated with low-grade squamous intraepithelial lesion (P < .05).
Conclusion:
Passive smoke exposure is an important independent risk factor for cytological abnormalities in Hispanic and non-Hispanic women. This study adds to the growing body of evidence of the dangers of passive smoke exposure.
