Models were adjusted for sex, age, race, education, energy, diabetes, hypertension, hypertension medication, BMI, HDL-C, family PIR, and total cholesterol. Continuous, Ln-transformed concentration of fatty acids; Q, quartile; 95% CI, 95% confidence interval; PIR, the ratio of income to poverty, BMI, body mass index; HDL-C, high-density lipoprotein; AAC, abdominal aortic calcification; SFA, saturated fatty acid; MUFA, monounsaturated fatty acid; PUFA, polyunsaturated fatty acid. * indicates p < 0.05, indicating statistical significance
