Abbreviations: BMI, body mass index; NHANES, National Health and Nutrition Examination Survey.
SI conversion factors: To convert total cholesterol values to mmol/L, multiply by 0.0259; to convert glucose values to mmol/L, multiply by 0.0555.
See Table 1, footnote “a.”
For trends across the surveys using logistic regression model adjusted for age, sex, and race/ethnicity; all tests 2-tailed.
All nonpregnant participants 20 years or older with available cardiovascular health metrics were included in trends analyses for each specific metric; therefore, sample sizes might vary by the cardiovascular health metrics.
Ideal: 150 minutes per week or more at moderate intensity or 75 minutes per week or more at vigorous intensity or 150 minutes per week or more at moderate + vigorous intensity. Intermediate: 1 to 149 minutes per week at moderate intensity or 1 to 74 minutes per week at vigorous intensity or 1 to 149 minutes per week at moderate + vigorous intensity. Duration (time) of the physical activity was not ascertained in NHANES III; see “Methods” for details of classification of physical activity. P value for trends compared NHANES 1999–2004 and NHANES 2005–2006.
Calculated as weight in kilograms divided by height in meters squared.
See “Methods” for details of calculation of healthy diet score. Trends may be attributed to change in questionnaires from NHANES III to NHANES 1999–2004 and NHANES 2005–2010.
Untreated value.
Fasting glucose level was available for the subsample of participants in NHANES III, NHANES 1999–2004, and NHANES 2005–2010.
See “Methods” for details of calculation of cardiovascular health metrics scores.
