Abstract：
OBJECTIVE: Our aim was to identify independent determinants of rapid weight gain in infants at 3-4, 6, and 12 months of age.
METHODS: A cohort study was conducted on Mexican term infants in public and private settings between March 2021 and May 2023. Rapid weight gain was defined as a ≥0.67 SD change in weight-for-age-Z-score from birth to 3-4, 6, and 12 months of age. Maternal and infant characteristics were described, and infant feeding practices, appetitive traits, weight, and length were analysed at 3-4, 6, and 12 months of age. Rapid weight gain predictors were determined using generalised linear regression models.
RESULTS: In total, 168 infants were recruited (55% boys). Small-for-gestational-age status increased rapid weight gain risk 1.5 times, whereas large-for-gestational-age status represented a 20%-30% decrease. Slowness in eating decreased the risk by 10%. Protective factors were older maternal age and higher educational level, whereas formula feeding, early complementary feeding, greater food enjoyment, and satiety responsiveness increased the risk.
CONCLUSIONS: Small for gestational age, slowness in eating, and feeding practices can be rapid weight gain predictors across the first year of life.

摘要：
目的：我们的目的是确定3-4、6和12月龄婴儿体重快速增加的独立决定因素。
方法：在2021年3月至2023年5月期间，在公共和私人环境中对墨西哥足月儿进行了一项队列研究。体重快速增加被定义为从出生到3-4、6和12月龄的年龄Z评分变化≥0.67SD。描述了母婴特征，和婴儿喂养的做法，食欲特征，体重,和长度在3-4,6和12个月大时进行分析。使用广义线性回归模型确定快速体重增加预测因子。
结果：总计，共招募168名婴儿（55%为男孩）。小于胎龄儿的体重快速增加风险增加1.5倍，而大于胎龄状态则减少了20％-30％。吃得缓慢会使风险降低10%。保护因素是母亲年龄较大，文化程度较高，而配方喂养，早期补充喂养，更大的食物享受，和饱腹感反应性增加了风险。
结论：小于胎龄，吃得很慢，和喂养方法可以在出生后的第一年快速增加体重。
