aNHANES, National Health and Examination Survey.
bSex, race/ethnicity, and total values are age-adjusted to the 2000 census estimated population, using the four age categories shown in the table.
cNo statistically significant differences (p>0.05, t-statistic) existed between NHANES 1999–2000 and NHANES III across any subgroup in the table.
dTotals for the race/ethnicity or country of birth categories do not add up to the total number because of an “other” category for race/ethnicity (not shown) or because persons did not provide a response to country of birth questions.
