RESUMEN
BACKGROUND: Young Australian women from culturally and linguistically diverse (CALD) backgrounds are vulnerable to unwanted pregnancy. We aimed to assess whether an online educational video, co-designed with young CALD women, can increase their contraceptive knowledge, preference for and uptake of long-acting reversible contraception (LARC). METHODS: Online advertising was used to recruit young CALD women aged 16-25 years. Participants completed the pre-video survey (S1), watched the 13-min co-designed video, then completed a survey immediately afterwards (S2) and 6 months later (S3). Outcomes were analysed using McNemar tests and multivariate logistic regression. RESULTS: A total of 160 participants watched the video, completed S1 and S2, and 57% of those completed S3. At S1 only 14% rated their knowledge about every contraceptive method as high. Knowledge improved at S2 for all methods (aOR 3.2, 95% CI 2.0 to 5.0) and LARC (aOR 4.7, 95% CI 2.9 to 7.5). Overall method preference for LARC increased from 2.5% (n=4) at S1 to 51% (n=82) at S2. Likelihood of using a LARC increased at S2 (aOR 3.8, 95% CI 2.6 to 5.6). The overall proportion of participants using a LARC increased from 8% at S1 to 11% at S3; however, this increase was not significant (p=0.7). CONCLUSIONS: The significant increase in knowledge, likelihood of use, and preference for LARC underscores the potential of online video-based contraceptive education to address contraceptive knowledge gaps and challenge misconceptions about LARC held by young women. Combining contraceptive education with supports to LARC access is crucial for empowering young CALD women to make informed contraceptive decisions.
RESUMEN
Background: Identifying optimal COVID-19 policies is challenging. For Victoria, Australia (6.6 million people), we evaluated 104 policy packages (two levels of stringency of public health and social measures [PHSMs], by two levels each of mask-wearing and respirator provision during large outbreaks, by 13 vaccination schedules) for nine future SARS-CoV-2 variant scenarios. Methods: We used an agent-based model to estimate morbidity, mortality, and costs over 12 months from October 2022 for each scenario. The 104 policies (each averaged over the nine future variant scenarios) were ranked based on four evenly weighted criteria: cost-effectiveness from (a) health system only and (b) health system plus GDP perspectives, (c) deaths and (d) days exceeding hospital occupancy thresholds. Findings: More compared to less stringent PHSMs reduced cumulative infections, hospitalisations and deaths but also increased time in stage ≥3 PHSMs. Any further vaccination from October 2022 decreased hospitalisations and deaths by 12% and 27% respectively compared to no further vaccination and was usually a cost-saving intervention from a health expenditure plus GDP perspective. High versus low vaccine coverage decreased deaths by 15% and reduced time in stage ≥3 PHSMs by 20%. The modelled mask policies had modest impacts on morbidity, mortality, and health system pressure. The highest-ranking policy combination was more stringent PHSMs, two further vaccine doses (an Omicron-targeted vaccine followed by a multivalent vaccine) for ≥30-year-olds with high uptake, and promotion of increased mask wearing (but not Government provision of respirators). Interpretation: Ongoing vaccination and PHSMs continue to be key components of the COVID-19 pandemic response. Integrated epidemiologic and economic modelling, as exemplified in this paper, can be rapidly updated and used in pandemic decision making.
