The Sandyford Initiative, Glasgow, UK

Objective: To assess the prevalence of chlamydia in female sex workers

in a Scottish industrial city. Set in Base 75, (a drop-in service for female sex

workers in Glasgow), which is part of the Sandyford Initiative for sexual health

in the city.

Method: Retrospective audit of chlamydia testing over a seventh month

period was undertaken. All swabs and urinary tests taken over a seven month

period were included. Note was taken of sociodemographic and drug using details,

chlamydia test result, whether or not symptomatic, and any antibiotic use over

the previous three months. Results were collated and analysed.

Results: Preliminary results show that 317 women used the service

during that period. 156 tests were done, 14 were positive (8.9%) and 3

inconclusive (1.9%). Of the first batch of 73 results analysed, 40 (54%) were

injecting drug users and 3 (4.1%) were non injecting users, all of whom were

street workers. 17 (23%) had had antibiotics in the last 3 months.

Conclusion: Chlamydia prevalence was lower than some reported rates in

other GUM and FP settings in the UK. One possible explanation could be that high

condom use is generally reported in this group. About 25% of the women however

had antibiotics in the previous three months for unrelated conditions which

could have opportunistically treated undetected chlamydia infection in these

women. These findings show it is vital that continued accessible service

provision for this high risk group with multiple sexual contacts must be
