Success in eradicating COVID-19 will rely on the rate of vaccination adoption worldwide. Vaccine acceptance among vulnerable groups is critical for preventing the spread of COVID-19 and decreasing unnecessary deaths. The purpose of this study was to report on the willingness to obtain COVID-19 immunization and the factors related to its acceptance among Myanmar migrant workers in southern Thailand. This cross-sectional study consisted of 301 samples collected between October and November 2021 and analyzed using multiple logistic regression. Thirty-nine percent of workers intended to receive the COVID-19 vaccine within a year. The following factors were associated with obtaining the COVID-19 vaccine: a high level of perception of COVID-19 (AOR = 5.43), income less than or equal to 10,000 baht/month (AOR = 6.98), financial status at a sufficient level (AOR = 7.79), wearing a face mask in the previous month almost all the time (AOR =4.26), maintaining 1–2 m of distance from anyone in the last month (AOR =2.51), and measuring temperature in the previous month (AOR = 5.24). High reluctance to accept the COVID-19 vaccine among Myanmar migrant workers can influence efforts to eliminate COVID-19. Collaboration with all stakeholders is critical to helping Myanmar workers understand COVID-19, social measures, and preventive beliefs to increase vaccine uptake.

Alcohol use poses unique challenges for migrant workers. Existing literature is limited in understanding how various determinants interact to influence health, family relationships, and social outcomes in this population. This study aims to determine the prevalence of alcohol-related impacts and examine relationships between alcohol use, environmental factors, and their broader effects among Myanmar migrant workers in Thailand. This cross-sectional study surveyed 610 Myanmar migrant workers in Thailand (Sep 2023–Mar 2024) using multi-stage sampling approach. Paper-based questionnaires were utilized, and alcohol use was assessed using the Alcohol Use Disorders Identification Test (AUDIT), with scores categorized as low-risk (0–7), risky (8–19), and probable dependence (≥20). Alcohol-related outcomes were also assessed, and generalized linear mixed models identified associated factors. Of the 610 participants, the majority were male (73.93%), with a mean age of 34.80 years (SD = 10.61) and an age range of 18–73 years. The study found that 38.20% reported a moderate level of alcohol-related impact (95% CI: 34.41–42.12), while 0.82% reported a high level (95% CI: 0.34–1.95). While alcohol addiction significantly increased adverse outcomes (AOR = 1.70, 95% CI: 1.61–1.79), environmental and occupational factors demonstrated stronger associations, with rural residency being the strongest correlate (AOR = 6.52, 95% CI: 4.35–9.77), followed by housing problems (AOR = 5.00, 95% CI: 2.70–9.24). Other significant factors included longer work hours (AOR = 2.39, 95% CI: 1.02–5.60), daily work schedules (AOR = 2.39, 95% CI: 1.64–3.49), poor sleep quality (AOR = 2.09, 95% CI: 1.51–2.90), moderate/poor health (AOR = 2.11, 95% CI: 2.02–2.22), and strained co-worker relationships (AOR = 1.89, 95% CI: 1.88–1.90). These findings highlight that environmental and occupational factors are more strongly associated with alcohol-related impacts than alcohol dependence itself, supporting public health strategies that address structural conditions alongside individual-level interventions.
