Abstract Background International literature shows that transgender teens and young adults are more likely to report insomnia compared to cis-gendered individuals of the same age – often linked with discrimination or minority stress. Trans people often encounter health providers with limited knowledge of gender diversity. Objective to understand the education needs, knowledge, and attitudes of the perinatal health workforce in New Zealand when providing care for trans people. Methods Interviews with trans people who had engaged with perinatal services, informed the development of a workforce survey, alongside extensive consultation with Māori, health professionals and trans community groups. The survey was shared with perinatal care providers via their professional organisations and social media. It included questions about strategies utilised in their clinical practice towards trans inclusion, previous education opportunities and current needs, as well as attitudes towards gender diversity. Results Survey participants (n=476) reported using multiple strategies when providing inclusive practice for trans people. Gaps in knowledge to support inclusive practice were identified, along with support needs to ensure perinatal care providers are resourced to provide culturally safe and affirming care for trans people and whānau/families. Most respondents had not received education on gender-inclusive care but three quarters of them reported they would access this if available. Conclusions Survey results identified strategies for inclusive care as well as knowledge gaps, in relation to meeting trans people’s perinatal care needs. Findings led to recommendations for education, practice and policy which could readily apply to those supporting trans people to improve their sleep health.
