a
Adjust for age, sex, race, education level, and marital status.
b
Adjust for age, sex, race, education level, marital status, family PIR, smoking, drinking alcohol, BMI, total cholesterol, and fasting plasma glucose.
PAD, peripheral artery disease; OR, odds ratio; OR <1.0 means lower likelihood for PAD.
CI, confidence interval; PIR, poverty-to-income ratio; BMI, body mass index.
METs increases from Q1 to Q4.
*
Considered statistically significant p < 0.05.
