Ethnicity and obesity

Different ethnic groups vary in susceptibility to obesogenic environments and to the adverse consequences of obesity, for both genetic/physiological and cultural/behavioural reasons. Effective interventions may also depend on the social and cultural context in which they are applied. The study of ethnic differences, and of the impacts of migration on specific population groups, may provide important mechanistic insights into pathways to obesity risk and its adverse consequences. Additionally, information on the propensities of different ethnic groups to obesity and its adverse consequences will be valuable for clinical decision-making.

  • Ethnic differences and migration patterns provide useful experimental tools for gene-environment interaction studies and for research into cultural influences on obesity.
  • Research should aim to understand the genetic and environmental factors that cause variations in the prevalence and incidence of metabolic disorders and their antecedents in specific populations.
