FACTORS ASSOCIATED WITH VIETNAMESE STUDENTS’ SELF-PERCEIVED MENTAL HEALTH PROBLEMS DURING THE COVID-19 LOCKDOWN: A CROSS-SECTIONAL STUDY Abstract The COVID-19 pandemic has stated the critical importance of addressing the mental health care needs of students. With the abrupt and extensive changes brought about by the pandemic, such as lockdowns and shifts to online learning, students worldwide faced significant psychological challenges. This context led to a comprehensive study focusing on Vietnamese students, aiming to understand their perceptions of mental health amidst these unprecedented times. The research specifically targeted the initial lockdown phase, seeking to describe the prevalence of mental health issues and identify the factors contributing to these problems among students in Vietnam. By examining these aspects, the study aimed to provide insights into the mental well-being of students during a major global crisis. A cross-sectional study was conducted among 1889 students in North and South Vietnam from 30 August, 2021 to 5 September, 2021. Socio-demographic information was collected via an online survey and the SF-12 Mental Composite Score (MCS) was used to assess self-perceived mental health problems. The study results show that the prevalence of selfperceived mental health problems, defined by an MCS<1st quartile, was 21.9% (95%CI: 20%-23.8%) among students during the COVID-19 lockdown. Regression models indicated that the following factors were significantly related to self-perceived mental health problems: Female sex, not living with family, financial difficulty, decreased health status, decreased academic performance and decreased social relationships during the COVID-19 lockdown. The study showed that many factors related to student’s self-perceived mental health problems during COVID-19, affecting a significant number of students. Suggestions for teachers and university administrators were also discussed. ASEAN Journal of Psychiatry, Vol. 25 (8) October, 2024;1-9.

Soluble epoxide hydrolases (sEH) are enzymes present in all living organisms, metabolize epoxy fatty acids to 1,2-diols. sEH in the metabolism of polyunsaturated fatty acids plays a key role in inflammation. In addition, the endogenous lipid mediators in cardiovascular disease are also broken down to diols by the action of sEH that enhanced cardiovascular protection. In this study, sEH inhibitory guided fractionation led to the isolation of five phenolic compounds trans-resveratrol (1), trans-piceatannol (2), sulfuretin (3), (+)-balanophonin (4), and cassigarol E (5) from the ethanol extract of the seeds of Passiflora edulis Sims cultivated in Vietnam. The chemical structures of isolated compounds were determined by the interpretation of NMR spectral data, mass spectra, and comparison with data from the literature. The soluble epoxide hydrolase (sEH) inhibitory activity of isolated compounds was evaluated. Among them, trans-piceatannol (2) showed the most potent inhibitory activity on sEH with an IC₅₀ value of 3.4 µM. This study marks the first time that sulfuretin (3) was isolated from Passiflora edulis as well as (+)-balanophonin (4), and cassigarol E (5) were isolated from Passiflora genus.

A total of 200 housewives at home and street vendors were interviewed by using structured questionnaires, the result has indicated the insufficient knowledge of food safety, most of them never had lessons in food handling practices. The environmental sanitary condition and food handling practices at home were better than at the street side. Stagnant wastes were found around 59% of the selling places of street vendors. 71% street foods prepared 2 hours before. Contacted foods with bare hands usually during street food preparation (89%). The practices and knowledge of food safety should be encouraged. A training guide gives clear information on how food becomes contaminated and on the measures that should be taken to avoid such contamination is essential.

A total of 160 street food samples were examined for microbiological quality and food color additives. All food samples were not used unpermitted food color additive, and the rate of microbiological contamination was 20.6%. No S.aureus were found at the lowest dilution used for all samples of cooked meat. Foods served hot had low bacterial contamination.
