Immigrants to the United States may have an advantage in terms of healthier weight, but tend to gain excessive weight after arrival, and may suffer from obesity and related health conditions. Acculturation theory suggests that this increase in obesity risk is due to adoption of unhealthy western dietary behaviors, and assumes that “eastern/traditional” dietary behaviors prior to migration are healthier. While this assumption is supported by studies conducted several decades ago, the phenomenon of globalization that has risen since the 1990s has increased exposure to western ideas and behaviors in communities worldwide. Hence, today's immigrants are more likely to have already adopted less healthy behaviors that increase obesity risk prior to their arrival in the U.S., a phenomenon we term “pre-acculturation.” The present study investigates the role of pre-acculturation in obesity development among immigrants from the Philippines.Data come from the Health of Philippine Emigrants Study, fielded in 2017 (n = 1632). Pre-acculturation was measured with English proficiency, preparation to migrate, receiving care packages, texting, telephone, or internet contact with friends/family in the U.S. Outcomes included the body mass index (BMI, kg/m2), waist circumference (WC, cm), waist-to-height ratio (WHtR) and waist-to-hip-ratio (WHR). Covariates included age, gender, education, financial strain, physical activity, and diet.Migrants reported greater English proficiency, preparation, and a slightly lower WHtR than non-migrants, but did not differ on BMI, WC, or WHR. Preparation was associated with greater BMI, WC, and WHtR, and the effects of preparation status differed by migration status. Among migrants, more preparation was associated with greater BMI, WC, and WtHR. Further, among non-migrants, texting and telephone communications was related to lower BMI, WC, and WHR.In summary, pre-acculturation may be a risk factor for obesity in the Philippines, suggesting that binary notions of “Western” versus “eastern/traditional” cultures may be too simplistic.
