ABSTRACT
PURPOSE: COVID-19 control measures reduced face-to-face appointments at sexual health services (SHSs). Remote access to SHSs through online self-sampling was increased. This analysis assesses how these changes affected service use and STI testing among 15-24 year olds ('young people') in England. METHODS: Data on all chlamydia, gonorrhoea and syphilis tests from 2019-2020, among English-resident young people were obtained from national STI surveillance datasets. We calculated proportional differences in tests and diagnoses for each STI, by demographic characteristics, including socioeconomic deprivation, between 2019-2020. Binary logistic regression was used to determine crude and adjusted odds ratios (OR) between demographic characteristics and being tested for chlamydia by an online service. RESULTS: Compared to 2019, there were declines in testing (chlamydia-30%; gonorrhoea-26%; syphilis-36%) and diagnoses (chlamydia-31%; gonorrhoea-25%; syphilis-23%) among young people in 2020. Reductions were greater amongst 15-19 year-olds vs. 20-24 year-olds. Amongst people tested for chlamydia, those living in the least deprived areas were more likely to be tested using an online self-sampling kit (males; OR = 1.24 [1.22-1.26], females; OR = 1.28 [1.27-1.30]). CONCLUSION: The first year of the COVID-19 pandemic in England saw declines in STI testing and diagnoses in young people and disparities in the use of online chlamydia self-sampling which risk widening existing health inequalities.
