CL = confidence limits; NA = not applicable; NHANES = National Health and Nutrition Examination Survey; Ref = reference group.

All categories except age groups are age-standardized to the 2000 projected U.S. census population using the following age groups: 6–11, 12–19, 20–29, 30–39, 40–49, 50–59, 60–69, and 70 years and above.

Columns for categories may not add to totals because of item nonresponse.

P < 0.001 for linear test for trend among age groups.

P < 0.05, ¶ P < 0.01, # P < 0.001 for comparison of subgroup to reference group for each cofactor.

Relative standard error of the estimate > 30% and estimate may be considered unstable.

Total sample sizes for the reported race and Hispanic origin subgroups do not sum to the population total because population total includes those that did not self-select into any of the listed race and Hispanic origin groups or reported as multiracial.

All categories except age groups are age standardized to the 2000 U.S. census population using the following age groups: 6–19, 20–39, 40–59, and 60 years and above.

P < 0.001 for linear test for trend among age groups.

P < 0.05 for comparison of subgroup to reference group for each cofactor.

Estimate based on < 10 positive sample persons or relative standard error (RSE) > 30% (eight positives and RSE > 50% for those aged 6–19 years, three positives and RSE > 60% for Mexican Americans, RSE > 30% for All Hispanics, and RSE > 30% for households ≥ 1 persons per room) so estimate may be unstable. Results should be interpreted with caution.

Total sample sizes for the reported race and Hispanic origin subgroups do not sum to the population total because population total includes those who did not self-select into any of the listed race and Hispanic origin groups or reported as multiracial.

The journal regrets the error.
