The objective was to investigate the association between circulating plasma carotenoids and different cardiometabolic risk factors and the plasma fatty acid profile. This is a cross-sectional evaluation of baseline data conducted in a subcohort (106 women and 124 men) of an ongoing multi-factorial lifestyle trial for primary cardiovascular prevention. Plasma concentrations of carotenoids were quantified by liquid chromatography coupled to mass spectrometry. The associations between carotenoid concentrations and cardiometabolic risk factors were assessed using regression models adapted for interval-censored variables. Carotenoid concentrations were cross-sectionally inversely associated with serum triglyceride concentrations [-2.79 mg/dl (95% CI: -4.25, -1.34) and -5.15 mg/dl (95% CI: -7.38, -2.93), p-values = 0.0002 andd <0.00001 in women and men, respectively], lower levelsof plasma saturated fatty acids [−0.09% (95% CI: −0.14, −0.03) and −0.15 %(95% CI: −0.23, −0.08), p-values = 0.001 and 0.0001 in women and men,respectively], and higher levels of plasma polyunsaturated fatty acids [(0.12% (95% CI: −0.01, 0.25) and 0.39 % (95% CI: 0.19, 0.59), p-values = 0.065and 0.0001 in women and men, respectively] in the whole population. Plasmacarotenoid concentrations were also associated with higher plasma HDLcholesterol in women [0.47 mg/dl (95% CI: 0.23, 0.72), p-value: 0.0002], and lower fasting plasma glucose in men [−1.35 mg/dl (95% CI: −2.12, −0.59), p-value: 0.001] PB Frontiers Research Foundation SN 2296-861X YR 2022 FD 2022-09-05 LK http://hdl.handle.net/10668/20672 UL http://hdl.handle.net/10668/20672 LA en NO Marhuenda-Muñoz M, Domínguez-López I, Langohr K, Tresserra-Rimbau A, Martínez González MÁ, Salas-Salvadó J, et al.
