The solicitation of nutrition-related health advice on social media platforms is on the rise. However, there is a paucity of research on the distinctive nutrition-related concerns and needs faced by transgender and gender-diverse individuals. Understanding patterns of nutrition-related information-seeking behaviour is vital to advancing health promotion efforts within this community. This study aimed to characterise the nutrition-related questions posed by the transgender community on a prominent social media outlet, Reddit.

A qualitative, cross-sectional content analysis was conducted, focusing on the top 100 submissions (ranked by popularity) within a transgender-centric online subreddit (r/asktransgender). Data extraction was facilitated using the Application Programming Interface Pushshift. The content analysis was conducted using NVivo.

The study was situated within the discussion forum of the social media platform, Reddit.

A total of 148 references from 90 eligible posts were identified and coded. The major themes included the effects of hormone replacement therapy (HRT) on nutritional health (n 66), weight status (n 45), dietary needs and behaviours (n 21), physical activity and weight loss on body shape (n 9), social undermining (n 4) and effects of health behaviours on HRT (n 3).

This study underscores the pressing need for tailored and evidence-based nutrition guidelines and communication toolkits that specifically address the distinct needs and experiences of transgender individuals, particularly those undergoing HRT.
