   Abstract:
   

   Objectives

   We systematically reviewed the literature on risk factors for obesity in American Indians (AIs) and Alaska Natives (ANs) of all ages.

   Study design

   We searched titles and abstracts in PubMed with combinations of the following terms: obesity, body mass index (BMI), American Indian, Alaska Native, and Native American.

   Methods

   We limited our review to articles that provided an empirically testable claim about a variable associated with obesity, measured obesity as a dependent variable, and provided data specific to AI/ANs.

   Results

   Our final sample included 31 articles; 20 examined AI/AN youth (<18 years), and 11 examined AI/AN adults (≥18 years). Risk factors for obesity varied by age. In infants, low birth weight, early termination of breastfeeding, and high maternal BMI, and maternal diabetes increased the risk of childhood obesity. In children and adolescents, parental obesity, sedentary behaviors, and limited access to fruits and vegetables were associated with obesity. In adulthood, sedentary behaviors, diets high in fats and carbohydrates, stress, verbal abuse in childhood, and the belief that health cannot be controlled were associated with obesity.

   Conclusions

   Extant studies have three limitations: they do not apply a life course perspective, they lack nationally representative data and have limited knowledge of the resilience, resistance and resourcefulness of AI/ANs. Future studies that avoid these shortcomings are needed to inform interventions to reduce the prevalence of obesity in AI/ANs across the life course.
