ABSTRACT
Obesity among migrant populations represents a growing public health concern globally, shaped by complex interactions between biological, social, environmental, and cultural determinants. Migrants experience unique health challenges related to acculturation, socioeconomic status, dietary changes, physical activity patterns, psychosocial stress, discrimination, and limited access to healthcare services. Evidence indicates that migrant groups often exhibit lower obesity prevalence upon arrival in host countries but experience accelerated weight gain and a higher risk of overweight and obesity over time. These changes are further influenced by generational shifts, maternal and child health factors, and exposure to obesogenic environments. Understanding the epidemiology, determinants, and health consequences of obesity in migrants is essential for designing culturally tailored, equitable, and effective public health interventions. Addressing these challenges requires integration of community engagement, culturally adapted lifestyle programs, preventive healthcare, policy measures, and consideration of social determinants to reduce obesity-related morbidity and enhance overall well-being among migrant populations.

Keywords: Migrant health, Obesity epidemiology, Acculturation, Social determinants of health, and Public health interventions.
