Abstract

Objective To compare secular changes in body mass index (BMI) and left ventricular mass (LVM) in today's children versus children of a generation earlier. Study design All healthy patients aged 2 to 19 years who underwent echocardiography at a single US academic medical center in 1986 to 1989 (prior era) and 2008 (current era) were included in this retrospective cross-sectional study. BMI, BMI z score, LVM indexed to height (LVMI), LVM z score, and relative wall thickness were calculated. Cardiac geometries were assigned based on LVM z score and relative wall thickness and classified as normal, concentric hypertrophy, eccentric hypertrophy, or concentric remodeling. Stepwise regression analysis was performed to identify determinants of LVMI. Results There were 350 subjects in the prior era and 350 age- and sex-matched subjects in the current era. Mean BMI and LVMI were both significantly higher in the current era than in the prior era (BMI, 19.9 ± 5.6 kg/m(2) vs 18.1 ± 3.8 kg/m(2), P = .0004; LVMI, 32.7 ± 7.8 g/m(2.7) vs 31.5 ± 8.1 g/m(2.7); P = .02). Determinants of LVMI in both eras were BMI z score, younger age, male sex, and African-American race. Conclusions Today's children have higher BMI, LVMI, and predicted cardiovascular risk than their counterparts a generation earlier. Reversal of these trends is needed, and intervention is required.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
