Physical and mental health in young adults with heart disease - a national survey of Norwegian university students

Background: Young adults with heart disease constitute a growing group with the risk of cognitive and physical impairment. The knowledge of their academic performance and mental and physical health is, however, scant. This study aimed to compare young adults with CHDs or arrhythmia with their peers. Methods: Information on physical health (Somatic Symptom Scale-8), mental health problems (Hopkins Symptoms Checklist-25), quality of life (Satisfaction With Life Scale), physical activity, and academic performance was collected online in a national cross-sectional survey in Norway among students in higher education (the SHoT2018 study). Results: Among 50,054 students, 172 (0.34%) reported CHD and 132 (0.26%) arrhythmias. Students reporting arrhythmias scored significantly higher than the control group on somatic symptoms (OR = 2.3 (95% CI: 1.62-3.27)), anxiety (OR = 1.60 (1.08-2.37)), depression (OR = 1.49 (1.05-2.11)), self-harm, and suicide attempt (OR = 2.72 (1.56-4.75)), and lower quality of life (OR 1.64 (1.16-2.32)) and more loneliness (OR = 1.99 (1.28-3.10)) compared to participants without heart disease. Participants with CHD reported an increased somatic symptom burden (OR = 1.58 (1.16-2.16)). Despite a tendency to a higher score, this group did not differ significantly from the control group on anxiety or depression, quality of life, or loneliness. However, the risk of self-harm thoughts and suicidality was significantly increased (OR for suicide attempt 2.22 (1.3-3.77)). There was no difference between the groups on academic performance. Conclusions: Although Norwegian students with heart disease reported more somatic symptoms, their academic progress was not reduced compared to students without heart disease. Students with CHD or arrhythmias showed an increased risk of self-harm thoughts and suicidality.
