Adiposity rebound is thought to arise earlier in children with a high body-mass index (BMI) at age 3 years. To test this hypothesis we followed up a birth cohort. Our results indicate that earlier rebound arose in children who were tall at age 3 years, but that timing was not associated with BMI at age 3 years in boys, and arose later in girls with higher BMIs at age 3. Adiposity rebound also arose earlier in children whose parents had high rather than low BMIs. Magnitude of BMI at rebound was associated with height and BMI at age 3, and with parental BMI. There was a correlation between age at rebound and age at menarche, which suggests that timing of rebound is an indicator of physical maturity rather than obesity.
肥胖反弹被认为在3岁时体重指数（BMI）较高的儿童中出现得更早。为了验证这一假设，我们对一个出生队列进行了随访。我们的结果表明，3岁时较高的儿童出现肥胖反弹更早，但在男孩中，肥胖反弹的时间与3岁时的BMI无关，而在3岁时BMI较高的女孩中出现得更晚。父母BMI高的儿童比BMI低的儿童肥胖反弹也更早。肥胖反弹时的BMI幅度与3岁时的身高和BMI以及父母的BMI有关。肥胖反弹年龄与初潮年龄之间存在相关性，这表明肥胖反弹时间是身体成熟度的指标，而非肥胖的指标。
