Abdominal aortic calcification (AAC), metabolic syndrome, and low bone mineral density (BMD) are risk factors for atherosclerotic disease and cardiovascular morbidity. We evaluated AAC in 662 adult survivors of childhood ALL (median age 31 years). AAC was present in 10% of subjects, metabolic syndrome in 36%, and low BMD in 29%. The adjusted odds ratio (OR) for AAC among women with metabolic syndrome was 2.3 (95% CL = 1.0, 4.3). The adjusted OR for AAC in men with low BMD was 3.1 (95% CL = 1.3, 7.3). A substantial proportion of adult survivors of childhood ALL have AAC and/or metabolic syndrome, suggestive of early atherosclerotic disease.
