Abbreviation: CI, confidence interval.
a Includes participants who reported that a health care provider had ever told them that they had high cholesterol. Excludes participants who said they had not had their cholesterol checked.
b Includes nonpregnant participants aged 25 years or older to allow comparison with WAHS data.
c Categories are mutually exclusive; participants classified at higher levels of certainty were not considered for lower levels. See Methods section for definitions of each category.
