A Social Media Survey of US Adolescent Preferences for Menstrual Bleeding Patterns

Study Objective: To assess preferences for menstrual pattern and acceptability and knowledge about the safety of induced amenorrhea among adolescents and young adults Methods: We conducted a cross-sectional online survey of US residents aged 14-24 years at least 1 year post -menarche. Online recruitment was conducted via the social media platform TikTok on a teen reproductive health channel. Survey questions focused on menstrual history, menstrual pattern preferences, and demographic characteristics. The primary outcome was the proportion of postmenstrual individuals who would prefer amenorrhea vs scheduled bleeding. Results: From 5113 potential respondents who accessed the eligibility screening, 3001 completed surveys and met the inclusion criteria. Most were aged 14-18 (63.7%), distributed proportionally among all US Census regions. When asked if they could pick their period -bleeding style without any permanent impacts, almost three-quarters chose no bleeding at all (amenorrhea; 71.5%) compared with scheduled periods (28.5%). However, 63.7% agreed or were uncertain when faced with the statement "It might be unsafe if hormone medications stop your period bleeding. " After adjusting for age, gender expression, race, religion, heavy bleeding, and frequent bleeding, factors associated with preference for amenorrhea vs regular bleeding were younger age, masculine gender expression, White race, and non-Christian religious background. Baseline bleeding amount and frequency were not associated with preference for amenorrhea. Conclusion: More than two-thirds of US adolescents and young adults indicated a preference for medication -induced amenorrhea if the method was assured to not have any permanent effects on the body, despite highly prevalent misconceptions about health and safety.
