Abstract:
Objective: Adiposity, not blood pressure (BP), is associated with left ventricular hypertrophy (LVH) among hypertensive children without chronic kidney disease (CKD). We aimed to determine the longitudinal association of BMI z-score with LVH and left ventricular mass index (LVMI) among children with CKD. Methods: 696 participants of the Chronic Kidney Disease in Children study with echocardiography results who contributed a total of 1,300 visits were included. Mixed models, adjusting for repeated visits with a random subject effect, were used to determine the longitudinal association of body mass index (BMI) z-score with LVMI and LVH (LVMI 〉 age-sex specific 95 th %ile). Models were adjusted for age, sex, race, systolic and diastolic BP z-score, glomerular diagnosis, time with CKD, glomerular filtration rate and calcium*phosphorus product and accounted for informative censoring. Results: Baseline characteristics are in the table. Among females, a 1 unit increase in BMI z-score was associated with an 8.5% increase in LVMI and 3.4 greater odds of LVH, whereas with boys, a 1 unit increase in BMI z-score was associated with a 5.2% increase in LVMI and a 1.4 greater odds of LVH (p 〈 0.05 for all). Conclusions: Among children with mild-moderate CKD, adiposity is independently associated with LVMI and LVH over time. This association is greater among females, a finding that may have future clinical and research implications.
