Abnormal cervical smears: are we in for an epidemic?
British Medical Journal (Clinical Research Ed.)
|August 20, 1983
Summary
Abnormal cervical smear rates significantly increased in a health district, particularly in women under 40. This suggests a true rise in premalignant cervical lesions, necessitating improved screening strategies.
Area of Science:
- Gynecology
- Public Health
- Epidemiology
Background:
- A notable increase in abnormal cervical smears was observed in a specific health district.
- This trend prompted an investigation into the underlying patterns and potential causes.
Purpose of the Study:
- To analyze the pattern of increased abnormal cervical smears over a 15-year period (1965-1979).
- To identify demographic and screening-related factors associated with the rise in abnormal findings.
Main Methods:
- Retrospective analysis of cervical smear records from 1965 to 1979.
- Data stratified by age, screening status, lesion severity, and geographic residence.
Main Results:
- Increased detection rates for abnormal cervical smears in both unscreened (5.8 to 12.9/1000) and screened (0.9 to 3.6/1000) women.
- The increase was proportionally higher in women under 40 years old.
- A significant population increase, skewed towards younger age groups, was the primary epidemiological variable.
Conclusions:
- The observed rise in abnormal cervical smears likely indicates a true increase in the incidence of premalignant cervical lesions.
- Enhanced, computer-aided cervical cancer screening programs are recommended nationwide to target high-risk populations.
- Proactive screening measures are crucial to prevent a future increase in cervical cancer rates.
