Our aim was to identify independent determinants of rapid weight gain in infants at 3-4, 6, and 12 months of age.
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.
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.
Small for gestational age, slowness in eating, and feeding practices can be rapid weight gain predictors across the first year of life.
本研究旨在确定婴儿在 3-4、6 和 12 个月时体重快速增加的独立决定因素。
本队列研究于 2021 年 3 月至 2023 年 5 月在公立和私立医疗机构中对墨西哥足月婴儿进行。体重快速增加定义为从出生到 3-4、6 和 12 个月时体重与年龄 Z 评分的变化≥0.67 SD。描述了母亲和婴儿的特征，并在 3-4、6 和 12 个月时分析了婴儿的喂养方式、食欲特征、体重和身长。使用广义线性回归模型确定体重快速增加的预测因素。
共纳入 168 名婴儿（55%为男孩）。小于胎龄儿状态使体重快速增加的风险增加 1.5 倍，而大于胎龄儿状态使风险降低 20%-30%。进食速度较慢使风险降低 10%。保护因素为母亲年龄较大和受教育程度较高，而配方奶喂养、早期补充喂养、更高的食物享受和饱腹感反应增加了风险。
小于胎龄儿、进食缓慢和喂养方式可能是婴儿出生后第一年体重快速增加的预测因素。
