Abstract

Background: Myanmar migrant workers in Southern Thailand contribute significantly to the local economy but face challenges including harmful drinking patterns and poor environmental conditions that negatively impact their social interactions. Understanding these factors is crucial for developing effective interventions. Objectives: To examine how alcohol consumption and environmental conditions affect social relationship problems among Myanmar migrant workers in Southern Thailand. Methods: A cross-sectional survey was conducted among 516 Myanmar migrant workers who consume alcohol. Data were collected through structured interviews covering demographic characteristics, drinking patterns, and social relationship issues. Statistical analysis using Generalized Linear Mixed Models identified factors associated with social relationship problems. Results: Nearly two-thirds of participants (63.37 %, 95 %CI: 59.11–67.43) experienced at least one social relationship problem. Major risk factors included harmful drinking patterns (AOR=2.61, 95 %CI: 2.26–3.01), working in agriculture (AOR=2.04, 95 %CI: 1.17–3.55), and insufficient income (AOR=2.01, 95 %CI: 1.18–3.41). Workers living in rural communities (AOR=3.58, 95 %CI: 1.81–7.06) and those facing moderate-to-high workplace environmental problems (AOR=3.14, 95 %CI: 2.52–3.91) also showed significantly higher risks. Conclusion: This study highlights the critical roles of alcohol consumption and environmental factors in shaping social relationships among Myanmar migrant workers. Interventions should target harmful drinking behaviors, improve workplace conditions, and promote social integration to enhance the well-being of this vulnerable population.
