1. The prevalence of composite sexually transmitted
infections (STIs) was 1.9%, with 1.2% among
men and 2.5% among women, and similarly for
chlamydia at 1.4% overall, with 1.2% for men and
1.7% for women.
2. However, the prevalence of chlamydial infection was 5.8% in young sexually active women, 4.8% in the sexually active men, and 4.1% in sexually active women aged 40 to 49 years.
3. Three independent risk factors were identified for both composite STIs and chlamydia: younger age, living alone, and males (or females with male partners) travelled outside Hong Kong in the past 12 months.
4. Mandatory surveillance and reporting of STIs and large population-based screening of chlamydia should be considered.
