This study aimed to investigate the DD and the influencing determinants among Myanmar university students in Chiang Mai, Thailand. A cross-sectional study was conducted in three universities in Chiang Mai province using a self-administered online survey from 3^rd October to 5^th November 2024. The determinants on dietary diversity score (DDS) were evaluated using multivariable analysis with multiple linear regression. A total of 170 students, 88 (51.76%) males, and 82 (48.24%) females participated in the study. The median (IQR) DDS was 6 ± 3, one score was the minimum and nine was the highest DDS. The social determinants associated with DDS included gender, religion, self-efficacy, skipping meals due to not readiness of food, stress, eating meals with family members and others, receiving dietary suggestions from friends, limitations to diverse foods access, religious restrictions and food advertisements on billboards. Multisectoral behavior-change measures targeting different tiers of the socio-ecological model, ranging from individual to community influences, must be carried out to improve the proper dietary behaviors and diversity of the university students.Pharmacology, Toxicology and PharmaceuticsEnvironmental ScienceAgricultural and Biological SciencesDentistryHealth ProfessionsArticleSCOPUS10.12982/NLSC.2026.0422-s2.0-10503390620528220838
