title: Association of acculturation, nativity, and years living in the United States with biobanking among individuals of Mexican descent.
abstract: BACKGROUND
  Biobanking is the collection of human biospecimens (tissues, blood, and body fluids) and their associated clinical and outcome data. Hispanics are less likely to provide biologic specimens for biobanking. The purpose of this study was to investigate the association of acculturation, nativity status, and years living in the United States with participation in biobanking among individuals of Mexican descent.
  
  
  METHODS
  Participants were 19,212 adults of Mexican descent enrolled in an ongoing population-based cohort in Houston, TX. Participants were offered the opportunity to provide a blood, urine, or saliva sample for biobanking. Acculturation was assessed with the bidimensional acculturation scale for Hispanics and scores were categorized into "low acculturation," "bicultural," and "high-acculturation."
  
  
  RESULTS
  After multivariable adjustment, we found an increased likelihood of participation in biobanking among individuals classified as "bicultural" as compared with "highly acculturated" individuals [OR, 1.58; 95% confidence intervals (CI), 1.10-2.26]. The associations of nativity status and years living in the United States with biobanking were not statistically significant. After stratifying by gender, the associations of acculturation, nativity status, and years living in the United States with biobanking were not statistically significant.
  
  
  CONCLUSIONS
  Although individuals of Mexican descent who were "bicultural" were more likely to participate in biobanking than individuals who were "highly acculturated," the difference in rates of participation among acculturation categories was small. The high participation rate in biospecimen collection is likely due to extensive community-engaged research efforts. Future studies are warranted to understand individuals' participation in biobanking.
  
  
  CONCLUSIONS
  Community-engaged research efforts may increase Hispanics' participation in biobanking. Cancer Epidemiol Biomarkers Prev; 23(3); 402-8. ©2014 AACR.
