He holds a Ph.D. degree from the International Ph.D. Program in Medicine, College of Medicine, Taipei Medical University, Taiwan. His research focuses on psychological health, quality of life, health behaviors, health literacy, and infectious diseases. He has published 12 original research articles in prestigious journals (ranking Q1, Q2 in SCI, and SSCI). Currently, he is participating in several projects, including COVID-19-related research projects, mental health in the elderly in Bangladesh, and health literacy in Hongkong.

Abstract:

Background
Many countries around the world have applied restrictive measures such as lockdown to control the spread of COVID-19, which can adversely affect people's psychological health and eating habits. Therefore, this study aimed to explore the impacts of COVID-19 lockdown on changes in eating behavior and mental health; and further examine whether digital healthy diet literacy (DDL) could modify these associations.

Methods
A cross-sectional study was conducted in Vietnam from 7th April to 31st May 2020. Data of 4348 outpatients from 11 hospitals were collected, including demographic characteristics, eating behaviors and mental health changes, DDL, comorbidities. We used logistic regression and interaction models to explore associations.

Results
COVID-19 lockdown was negatively associated with having unchanged or healthier eating behaviors (OR = 0.38; 95%CI = 0.29 – 0.51; p < 0.001) and stable or better mental health (OR = 0.77; 95%CI = 0.67 – 0.89; p < 0.001). In interaction models, the adverse impact of COVID-19 lockdown on unchanged or healthier eating was attenuated by higher DDL values from 1 SD below the mean (OR = 0.22, 95%CI = 0.15 - 0.34; p < 0.001), the mean (OR = 0.39; 95%CI = 0.30 - 0.54; p < 0.001), to 1 SD above the mean (OR = 0.70; 95%CI = 0.50 - 0.99, p = 0.048). Similarly, the negative impact of COVID-19 lockdown on stable or better mental health was attenuated by higher DDL values from 1 SD below the mean (OR = 0.60; 95%CI = 0.50 - 0.72; p < 0.001), the mean (OR = 0.79; 95%CI = 0.69 - 0.91; p = 0.001), to 1 SD above the mean (OR = 1.05; 95%CI= 0.84 - 1.30, p = 0.665).

Conclusions
The COVID-19 lockdown could adversely affect eating behavior, and mental health in outpatients. The DDL improvement could mitigate the negative impacts of the lockdown, which may help outpatients to maintain positive lifestyles and mental health.
