Figure 1. Age-adjusted prevalence of dyslipidemia
for Alaska EARTH Study participants, 2004-2006, compared with Alaska NHANES
participants, 1999-2004. Direct age standardization is based on the 2000
census standard population for adults aged 20 years or older using age
groups 20 to 34 years, 35 to 44 years, 45 to 54 years, 55 to 64 years, and
65 years or older. Clinical risk factor categories for EARTH Study
participants are based on recommendations from the National Cholesterol
Education Program (11). Clinical risk factor categories for NHANES participants
are based on Health, United States, 2007 (16), Hyre et al (19), and Kuklina et al (20). Abbreviations: EARTH, Education and Research Towards Health;
CI, confidence interval; NHANES, National Health and Nutrition Examination
Survey; LDL, low-density lipoprotein; HDL, high-density lipoprotein.

Figure 2. Age-adjusted prevalence of clinical risk factors for Alaska EARTH Study participants, 2004-2006, compared with Alaska NHANES
participants, 1999-2004. Direct age standardization is based on the 2000 census
standard population for adults aged 20 years or older using age groups 20 to 34
years, 35 to 44 years, 45 to 54 years, 55 to 64 years, and 65 years or older.
Clinical risk factor categories for EARTH Study participants are based on
recommendations from the American Diabetes Association and the Joint National
Committee on Prevention, Detection, Evaluation, and Treatment of High Blood
Pressure (12,13). Clinical risk factor categories for NHANES participants
are based on Health, United States, 2007 (16) and Cowie et al (17). Abbreviations: EARTH, Education and Research Towards Health;
CI, confidence interval; NHANES, National Health and Nutrition Examination
Survey.
