The anthropometric and cardiometabolic characteristics of O‐OW were compared with those of O‐NW, and the relationship to maternal BMI was evaluated.</p> </sec> <sec id="pedi12273-sec-0003" sec-type="section"> <title>Results</title> <p id="pedi12273-para-0003">Subjects (mean age: 12.6 ± 0.4, female: 52.9%) had similar gestational age, birth weight, age, gender, and Tanner stage. However, O‐OW had a significantly higher BMI (24.4 ± 1.2 vs. 19.7 ± 0.8 kg/m<sup>2</sup>, p = 0.001), % body fat (31.7 ± 1.6 vs. 24.6 ± 1.1%, p < 0.001), visceral fat (41.9 ± 4.7 vs. 26.1 ± 3.9 cm<sup>2</sup>, p = 0.012) with no difference in lean body mass compared with O‐NW. O‐OW had lower whole body insulin sensitivity index (WBISI) with an adverse cardiovascular disease risk profile [higher blood pressure (BP), triglycerides to high‐density lipoprotein (HDL) ratio, hs‐C‐reactive protein (CRP) and lower HDL]. In addition to offspring's %body fat (β = −0.60, p < 0.001), maternal pre‐pregnancy BMI (β = −0.19, p = 0.046) contributed significantly and independently to the offspring's WBISI (R<sup>2</sup>=0.55, p < 0.001).</p> </sec> <sec id="pedi12273-sec-0004" sec-type="section"> <title>Conclusions</title> <p id="pedi12273-para-0004">High pre‐pregnancy BMI is an important contributor to excess adiposity, insulin resistance, and cardiometabolic disease risk in the offspring during childhood.</p> </sec> </abstract>
