| Zusammenfassung: | <jats:sec xml:lang="en"> <jats:title>Background</jats:title> <jats:p xml:lang="en"> High‐throughput nuclear magnetic resonance profiling of circulating metabolites is suggested as an adjunct for cardiovascular risk evaluation. The relationship between metabolites and subclinical atherosclerosis remains unclear, particularly among children. Therefore, we examined the associations of metabolites with carotid intima‐media thickness ( <jats:styled-content style="fixed-case">cIMT</jats:styled-content> ) and arterial pulse wave velocity ( <jats:styled-content style="fixed-case">PWV</jats:styled-content> ). </jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Methods and Results</jats:title> <jats:p xml:lang="en"> Data from two independent population‐based studies was examined; (1) cross‐sectional associations with <jats:styled-content style="fixed-case">cIMT</jats:styled-content> and <jats:styled-content style="fixed-case">PWV</jats:styled-content> in 1178 children (age 11–12 years, 51% female) and 1316 parents (mean age 45 years, 87% female) from the CheckPoint study (Australia); and (2) longitudinal associations in 4249 children (metabolites at 7–8 years, <jats:styled-content style="fixed-case">PWV</jats:styled-content> at 10–11 years, 52% female), and cross‐sectional associations in 4171 of their mothers (mean age 48 years, <jats:styled-content style="fixed-case">cIMT</jats:styled-content> data) from <jats:styled-content style="fixed-case">ALSPAC</jats:styled-content> (The Avon Longitudinal Study of Parents and Children; <jats:styled-content style="fixed-case">UK</jats:styled-content> ). Metabolites were measured by the same nuclear magnetic resonance platform in both studies, comprising of 69 biomarkers. Biophysical assessments included body mass index, blood pressure, <jats:styled-content style="fixed-case">cIMT</jats:styled-content> and <jats:styled-content style="fixed-case">PWV</jats:styled-content> . In linear regression analyses adjusted for age, sex, body mass index, and blood pressure, there was no evidence of metabolite associations in either children or adults for <jats:styled-content style="fixed-case">cIMT</jats:styled-content> at a 10% false discovery threshold. In CheckPoint adults, glucose was positively, and some high‐density lipoprotein‐cholesterol derived measures and amino acids (glutamine, histidine, tyrosine) inversely associated with PWV. </jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Conclusions</jats:title> <jats:p xml:lang="en"> These data suggest that in children circulating metabolites have no consistent association with <jats:styled-content style="fixed-case">cIMT</jats:styled-content> and <jats:styled-content style="fixed-case">PWV</jats:styled-content> once adjusted for body mass index and blood pressure. In their middle‐aged parents, some evidence of metabolite associations with <jats:styled-content style="fixed-case">PWV</jats:styled-content> were identified that warrant further investigation. </jats:p> </jats:sec> |
