Background. Rapid growth is associated with increased cardiometabolic risk (CMR) in adolescence and adulthood. Little is known about whether the association between rapid growth and increased CMR originates in early childhood.
Objectives. To identify age and sex standardized body mass index (zBMI) trajectories and to examine the association between zBMI trajectories and CMR outcomes in children 0 to 60âmonths.
Study design. A longitudinal cohort study was conducted through The Applied Research Group for Kids (TARGet Kids!) in Toronto, Canada. Participants had repeated measures of weight and length or height performed from birth to 60âmonths of age. Latent class mixed modelling was used to identify the zBMI trajectories. Linear regressions were performed to determine the association between zBMI trajectories and the primary outcome, a CMR score, quantified as the sum of ageâ and sexâ standardized waist circumference, systolic blood pressure, glucose, logâtriglycerides and negative highâdensity lipoprotein cholesterol (HDLâC), divided by â5. Secondary outcomes were the individual components of the CMR formula as well as diastolic blood pressure and nonâHDLâC.
Results. Four BMI trajectories were identified among the 1166 children. After adjusting for all covariates, children in the rapidly accelerating trajectory had increased total CMR score (Î˛ =â1.38, 95% CI 0.77; 1.99, P <â.001) and increased waist circumference score (Î˛ =â2.39, 95% CI 1.92; 2.86, P <â.001) compared to the stable low group.
Conclusions. Rapid growth during early childhood is associated with increased CMR in preschool children, largely driven by larger waist circumference.
