Menstrual Health Literacy among Adolescents and Young Adults Who Menstruate: Impact of Christian Family Background and United States Region

Study Objective: To compare menstrual health literacy among adolescents and young adults on the basis of family religious background and United States region Methods: We conducted a cross-sectional online survey of post-menarcheal US adolescents and young adults aged 14-24 years who identified their family religious background, including Christian or non-religious, with recruitment via the social media platform TikTok. We asked participants several questions to assess their health literacy regarding common myths about the use of gonadal steroid hormones for menstrual suppression. Results: From 3250 online survey respondents, 2997 met the criteria for analysis, with 1989 identifying their family as Christian (66.4%) and 1008 identifying their family as non-religious (33.6%), with equal representation by US region. Health literacy was lower among those with a Christian family background, with concerns that menstrual suppression is unhealthy (16.4% vs 10.5% with non -religious background, P < .01), is unsafe (31.4% vs 24.2%, P < .01), and could lead to infertility (32.6% vs 20.0%, P < .01). Similarly, adolescents and young adults from the US South were worried that menstrual suppression is unhealthy (31.5%; P < .01) and would lead to infertility (33.8%; P < .01). Conclusion: Health literacy is lower among adolescents and young adults with a Christian family background and those who live in the South. These results demonstrate a need for an evidence -based national curriculum that addresses the safe and effective use of hormonal medications for menstrual suppression.
