Means on the same row with the same superscript letter (a,b,c) were not statistically different (). SE = standard error of the mean. Means were adjusted for differences in age, and with the sample combined, age and sex. Alpha was 0.0675 for the mean difference between Mexican American and NH Asian men. When combined, the sample size percentages (%) and sample size numbers (n) were Mexican American (7.3%, n = 1847), Other Hispanic (5.7%, n = 1535), NH White (67.6%, n = 4881), NH Black (10.8%, n = 3274), NH Asian (5.3%, n = 1815), and Other or Multiracial (3.3%, n = 450). Because NHANES sample weights were applied to the percentages, differences in the sample sizes across the race categories should be interpreted based on the percentages (%), not the number (n).
