Background
Social connections between medical students provide a key basis for learning and support. These connections, and associated social identity, may be patterned by ethnicity, and students often perform similarly academically to those they connect with. The mechanisms that underpin the formation of these connections and the role that they play are not fully understood. This study explored how medical students connect with each other, and the potential impact of this on their academic attainment and well-being, with a focus on students with minoritised ethnic identities.

Methods
A mixed methods study combining (1) a survey to establish the number and strength of connections formed by Years 1 and 2 medical students with both minoritised and non-minoritised ethnicities and (2) semi-structured interviews to understand how connections were formed, whether this was shaped by ethnicity and the role of connections in supporting students with their learning and well-being.

Results
One hundred fifty-one students (15.5% response rate) completed the survey. Students connected regularly with three to four peers with the goal of supporting learning and 71.9% of students reported a sense of social identification with this group. There was no statistical difference between ethnically minoritised and White students on either of these measures (t = 0.1, p = 0.92, χ2 = 2.9, p = 0.56). Interviews with 19 students found that social connections were shaped by perceptions of their self-identity and the need to find ‘equilibrium’ by forming relationships with compatible others. The education environment, including its ethnic diversity, impacted on the opportunities to make connections. Students who were ethnically minoritised reported encountering challenges, especially in the clinical environment, and described the burden of these for them.

Discussion
Curriculum designers should consider the time and space that is afforded to student interaction during course development, as finding compatible others with whom students can socially connect is important to balancing well-being with academic performance.
