To determine age-specific incidence rates of cervical cytology abnormalities, as diagnosed by a cytopathology unit servicing a geographically defined area.
Cross-sectional descriptive study.
Cytopathology Unit at Tygerberg Hospital, a tertiary centre.
Altogether 117 133 cervical cytology smears were analysed over a 2-year period.
The peak incidence of cytological abnormalities occurs in the younger age groups (25 years and below).
A statistically significant (P=0.047) increase in low-grade squamous intra-epithelial lesions occurred in patients aged less than 20 years relative to those aged 20 - 24 years, with a subsequent decline in incidence with increasing age.
High-grade squamous intra-epithelial lesions were seen predominantly in the younger patients with a plateau in the 24 - 29-and 30 - 36-year age groups followed by a subsequent decline.
Abnormal cervical cytology has a peak incidence in young women, which emphasises the importance of planning a cervical cytology screening programme accordingly.
