Characteristics and gender affirming healthcare needs of transgender and non-binary students starting hormone therapy in a student health service in Aotearoa New Zealand.

Introduction Traditionally, gender-affirming hormonal therapy (GAHT) is initiated in secondary care, but a primary care based approach has been developed to reduce access barriers. Aim We aim to describe the demographics, hormone choices, and additional referrals made for young people initiating GAHT in a primary care setting in Aotearoa New Zealand. Methods Clinical notes were reviewed for all patients who commenced GAHT between 1 July 2020 to the end of 2022 at a tertiary education health service. Data were collected on age, ethnicity, gender, type of hormones prescribed, and any additional referrals. Results Eighty five patients commenced GAHT during the review period (64% assigned male at birth and starting oestrogen-based GAHT, 36% assigned female at birth and commencing testosterone-based GAHT). Fourty seven percent of patients identified as transgender female, 38% as non-binary, and 15% as transgender male. Spironolactone was the most common choice of testosterone blocker (81%). The choice of oestrogen formulation was fairly equal between patches (54%) and tablets (46%). Eighty percent of those assigned male at birth chose to preserve fertility, 54% requested voice therapy, and 87% of those assigned female at birth requested top surgery. Discussion There is a need for improved understanding of non-binary gender-affirmation needs, in particular those of Māori and Pasifika youth. An informed consent approach in primary care can reduce barriers and distress for transgender youth seeking GAHT. The high unmet need for top surgery for transgender people assigned female at birth requires attention.
