Background: Breakfast consumption has been associated with the improvement of many cardiovascular disease (CVD) risk factors, yet data regarding its association with subclinical vascular damage, which precedes the onset of CVD, are scarce. The aim of this study is to investigate this association in a large sample of adults with CVD risk factors.
Methods: Anthropometric measurements, vascular biomarkers and dietary intake with two 24-h dietary recalls, focusing on breakfast frequency and its quantity and content, were assessed in 902 adults (45.2% males). Breakfast quality was assessed by identifying a posteriori breakfast dietary pattern (DP) by using principal component analysis (PCA).
Results: Systematic breakfast consumption (SBC) was inversely associated with central systolic blood pressure (b: -3.28, 95% C.I.: -5.7 to -0.86), diastolic blood pressure (b: -1.85, 95% C.I.: -3.34 to -0.36), augmentation index (b: -3.17, 95% C.I.:-4.98 to 1.35) and left carotid intima media thickness (b: -0.03, 95% C.I.:-0.06 to -0.01) compared to breakfast skipping independently of age, sex, hypertension, diabetes, dyslipidemia, smoking, and BMI. SBC of 10-20% of daily total energy intake (dTEI) was inversely associated with Aix (b: -2.31, 95% C.I.:-4.05 to -0.57) compared to <10% dTEI after adjustment for the aforementioned confounders. DP1 (high coffee and sugar consumption, low consumption of low- and full-fat dairy products, fruits, and fresh juices) was positively associated with Aix (b: 1.19, 95% C.I.: 0.48 to 1.90).
Conclusion: SBC comprised of medium-energy density and high-nutrient content food items may be a simple daily habit associated with better vascular health.
