a
Adjusted for awake accelerometer wear-time, age, race-ethnicity, education, alcohol, age at menopause, self-rated general health and the other characteristics in the table.
b
Calculated using the following formula22: Pc(1−1/RRadj), where Pc is the prevalence of a risk factor among decedents and RRadj is the multivariable adjusteda relative risk for mortality associated with the specified risk factor.
