Bell, Ronny A., Elizabeth J. Mayer-Davis, Yvonne Jackson, and Connie Dresser. “An epidemiologic review of dietary intake studies among American Indians and Alaska Natives: implications for heart disease and cancer risk.” Annals of Epidemiology 7.4 (May 1997): 229-240.
This article arises from concern that, although the overall mortality rates from heart disease and cancer are lower among American Indians and Alaska Natives (AIANS) than in the general U.S. population, these rates may change as AIANS become further acculturated to Western lifestyles and adopt diets higher in fat and calories and lower in fiber. The authors found twelve studies, published between 1959 and 1996, with 20-575 subjects each. They reviewed these studies, along with other, related documents. Two studies of the Lumbee, authored by Ronny Bell, are included. Tables 4 (Dietary intake studies among AIAN populations) and 5 (Reported dietary heart disease and cancer risk factors from published studies among AIANS) include the Lumbee. Bell concludes that only limited information exists on the validity and reliability of instruments for dietary assessments of AIANS, and similarly small amounts of dietary intake data can be found for these populations--particularly longitudinal data on large samples of people. The existing data indicates that changes in diet, over time, may affect rates of heart disease and cancer in AIANS.
