Examining disparities in behavioral risks in a 2004 sample of American Indians compared with populations in North Dakota and the U.S.

^aAmerican Indian sample data were adjusted for age and gender using direct standardization to the 2000 U.S. population.

^bNorth Dakota and U.S. proportions presented are from the weighted data available from the Centers for Disease Control and Prevention.

^cData from 2005 North Dakota (n=4,010) and U.S. (n=356,112) samples were substituted because data were not collected in 2004.

^dProportions are significantly different from those in the same row (p<0.05) based on Chi-square analysis.

^eThe American Indian sample proportion is significantly different (p<0.05) from the U.S. proportion, but not the North Dakota (ND) proportion (p>0.05), and the ND and U.S. proportions are not significantly different (p>0.05).
