RESUMO
Background: Non-consensual sex including rape and sexual assault has been a global concern and may have been influenced by the COVID-19 pandemic, however the information on this topic is limited. Therefore, our objective was to survey the incidence rate of non-consensual sex among Japanese women aged 15-79 years between April to September 2020, following the COVID-19 pandemic in Japan. Materials and Methods: We utilized the data obtained from a nationwide, cross-sectional internet survey conducted in Japan between August and September 2020. Sampling weights were applied to calculate national estimates, and multivariable logistic regression was performed to identify factors associated with non-consensual sex. Data was extracted from a cross-sectional, web-based, self-administered survey of approximately 2.2 million individuals from the general public, including in men and women. Results: Excluding men and responses with inconsistencies, the final analysis included 12,809 women participants, with 138 (1.1%) reporting experiencing non-consensual sex within a five-month period. Being aged 15–29 years and having a worsened mental or economic status were associated with experiencing non-consensual sex. Conclusions: Early intervention to prevent individuals from becoming victims of sexual harm should be extended to economically vulnerable and young women, especially during times of societal upheaval such as the COVID-19 pandemic. Additionally, Japan should prioritize the implementation of comprehensive education on the concept of sexual consent.
