Understanding the Impact of Long COVID on the Lives of Thai University Students.

COVID-19 has had profound global impacts, and Long COVID may continue to affect quality of life and well-being in some individuals. Young adults may be particularly vulnerable to these impacts due to ongoing physiological, behavioral, and psychological development. This study aimed to examine the associations between Long COVID, mental health-related outcomes, and quality of life among university students. A total of 365 Thai undergraduate students participated in this cross-sectional study screening for Long COVID. Long COVID symptoms, mental health, sleep quality, and quality of life were assessed using validated Thai versions of the Long COVID Screening Questionnaire, DASS-21, PSQI, and EQ-5D-5L. Regression and group comparison analyses were conducted between participants with Long COVID and those without Long COVID. Fatigue and cough were the most reported symptoms, while sleep disturbances were also prevalent. Long COVID was associated with significantly lower quality of life scores (p = 0.035). However, no significant differences were observed in DASS-21 or PSQI scores between groups. Vaccination doses and prior COVID-19 infections differed significantly between groups (p < 0.001 and p = 0.017). These findings highlight the multisystem impacts of Long COVID and emphasize the importance of identification and supportive interventions to enhance student health and well-being.
