Abstract
OBJECTIVE: This study aimed to examine the association between baseline and changes in dietary quality assessed by the Alternative Healthy Eating Index-2010 (AHEI-2010) and abdominal aortic calcification (AAC) among community-dwelling older adults. DESIGN: Population-based longitudinal study. SETTING: A subset of the Melbourne Collaborative Cohort Study (MCCS). PARTICIPANTS: 262 community-dwelling adults (60% female) aged 53 ± 5 years at baseline. MEASUREMENTS: Dietary intake was assessed using validated Food Frequency Questionnaires at baseline (1990-1994) and follow-up (2010-2011). AAC was evaluated by radiography and dual-energy x-ray absorptiometry (DXA) at follow-up. RESULTS: Higher baseline AHEI-2010 score was associated with lower AAC severity by radiography [OR (95% CI) for Tertile 3 VS Tertile 1: 0.53 (0.29-0.99)] after adjustment for gender, age, physical activity, smoking, BMI, systolic blood pressure, plasma total cholesterol, calcium and energy intake. The association between AHEI-2010 and AAC severity by DXA was also significant in the multivariate-adjusted model [OR (95% CI) for Tertile 3 VS Tertile 1: 0.38 (0.20-0.70)]. Changes in AHEI-2010 over 18 years were not associated with AAC severity. CONCLUSION: Baseline but not the changes in AHEI-2010 was inversely associated with the risk of AAC severity suggesting that a high quality diet might help prevent or delay the progression of AAC in community-dwelling older adults and the benefits might be manifested over the long-term.
