Abstract

fetched live from OpenAlex

OBJECTIVES: We estimated the association between local public health infectious and communicable diseases (ICD) funding and chlamydia and gonorrhea trends before and during the COVID-19 pandemic among adolescents aged 13-19 in Ontario, Canada. STUDY DESIGN: Quasi-experimental, interrupted time series. METHODS: We conducted a population-based analysis using repeated cross-sectional data of chlamydia and gonorrhea incidence among adolescents across Ontario's 34 regional public health units from January 2015 to October 2022. We used negative binomial-regression to estimate changes in chlamydia and gonorrhea incidence before and during the COVID-19 pandemic, and whether these changes differed by 2019 ICD per capita public health funding. RESULTS: During the study period, there were 51,230 adolescent cases of chlamydia and 5256 of gonorrhea with most cases in females and older adolescents (age 18-19). Pre-pandemic, chlamydia rates increased over time (Risk ratio (RR) = 1.01, 95 % confidence interval (CI): 1.01-1.01, per month). There was an immediate decrease in chlamydia rates post-pandemic onset (RR = 0.26, 95 % CI: 0.12-0.53) though higher rates were observed with increasing 2019 ICD per capita funding (RR = 1.11, 95 % CI: 1.05-1.17, per dollar of ICD per capita funding, post-pandemic onset). Similar trends were observed for gonorrhea, but estimates had lower precision. CONCLUSION: Higher pre-pandemic 2019 ICD per capita funding may have allowed greater sexual health screening services during the COVID-19 pandemic, potentially mitigating a larger drop in STI detection. Results suggest that higher public health funding may allow for greater resilience of sexual health services during public health emergencies.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
