This 12-week randomized controlled trial investigated whether providing abdominal aortic calcification (AAC) results alongside educational resources improves fruit and vegetable intake compared to educational resources alone. 240 participants (57.5% female, aged 60-80) received either their AAC results (intervention) or not (control), both groups receiving cardiovascular disease risk control education. Primary outcomes were changes in fruit and vegetable intake (plasma carotenoids and food frequency questionnaire). No between-group differences were found in primary outcomes. However, providing AAC results led to improvements in serum total and non-HDL cholesterol and estimated cardiovascular disease risk score. This suggests that while AAC results may not directly improve diet, they may positively impact other cardiovascular risk factors.
