Children from minority groups are at increased risk of overweight. This study compared BMI growth patterns from birth onwards of boys and girls with overweight at 5-6 years, according to socioeconomic status (SES) and country of origin, in order to gain more insight into the critical periods of growth to overweight.
A total of 3714 singletons of the multi-ethnic ABCD study were included. Within children with overweight at age 5-6 years (N = 487, prevalence boys: 11.6%, girls: 14.6%), BMI growth patterns from birth onwards (12.8 serial measurements; SD = 3.1) were compared between children from European (69.4%) and non-European mothers (30.6%), and between children from low (20.8%), mid (37.0%) or high SES (42.2%), based on maternal educational level.
BMI growth to overweight did not differ between children of European or non-European mothers, but it did differ according to maternal SES. Children with overweight in the low and mid SES group had a lower BMI in the first 2 years of life, an earlier adiposity rebound and increased in BMI more rapidly after age 2, resulting in a higher BMI at age 7 years compared to children with overweight in the high SES group [∆BMI (kg/m ) between high and low SES: boys 1.43(95%CI:0.16;3.01) and girls 1.91(0.55;3.27)].
Children with overweight from low SES have an early adiposity rebound and accelerated growth to a higher BMI at age 5-6 years compared to children with overweight from the high SES group. These results imply that timing of critical periods for overweight development is earlier in children with a low socioeconomic background as compared to other children.
少数民族儿童超重的风险较高。本研究比较了超重的 5-6 岁男孩和女孩的 BMI 生长模式，根据社会经济地位（SES）和原籍国，以深入了解超重的关键生长阶段。
共纳入了多民族 ABCD 研究的 3714 名单胎。在超重的 5-6 岁儿童中（N=487，男孩患病率：11.6%，女孩患病率：14.6%），比较了欧洲（69.4%）和非欧洲母亲（30.6%）儿童以及低 SES（20.8%）、中 SES（37.0%）或高 SES（42.2%）儿童从出生到超重期间（12.8 次连续测量；SD=3.1）的 BMI 生长模式，依据是母亲的教育水平。
欧洲和非欧洲母亲的儿童的 BMI 增长到超重并没有差异，但 SES 不同。低 SES 和中 SES 组超重的儿童在生命的头 2 年 BMI 较低，脂肪量反弹较早，2 岁后 BMI 增长较快，导致 7 岁时 BMI 高于高 SES 组超重的儿童[高 SES 和低 SES 之间的 BMI 差异（kg/m）：男孩 1.43（95%CI：0.16；3.01）和女孩 1.91（0.55；3.27）]。
与高 SES 组超重的儿童相比，低 SES 组超重的儿童脂肪量反弹较早，到 5-6 岁时 BMI 增长较快。这些结果表明，与其他儿童相比，社会经济背景较低的儿童超重发展的关键时期更早。
