Copyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings ABC News: Noninfectious Conditions Discussion Questions:  What is the incidence of diabetes among Native Americans over the age of 40?  How has the federal government contributed to the poor nutritional status of Native Americans?  What percentage of Native Americans on reservations are unemployed? Does this have a relationship to the high rate of physical inactivity?  In an area 50 by 100 miles and a population of 38,000 how many fitness centers are available to Native Americans on this reservation?

Copyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings Digestion-Related Disorders  Diabetes is the fastest growing chronic disease in American history  2,200 people are diagnosed each day in America  Pancreas produces insulin in insufficient quantities to allow the body to use or store glucose  Type 1 require insulin injections because insulin is not present in the body  Type 2 insulin production is deficient or the body is unable to utilize available insulin  Gestational diabetes can develop in pregnant women
