Consumption of added sugars is linked to excess adiposity in older age groups and breastfeeding has been shown to protect against later obesity.
This investigation aimed to determine whether intake of added sugars associates with rapid weight gain in individuals under 2 years of age, if intake of added sugars associates with breastfeeding duration, and how both influence body weight.
A cross-sectional analysis of data from three 24-hours dietary recalls collected from 141 infants/toddlers (age 11.9 ± 1.9 months, 44.7% male) was performed. Multivariable regressions assessed relationships between added sugar intakes, breastfeeding duration, and weight status. Hierarchical regressions examined added variance accounted for in rapid weight gain (specifically, upward weight-for-age percentile [WFA %tile] crossing) through the interaction of added sugars * breastfeeding duration.
Added sugars correlated positively with upward WFA %tile crossing (r = 0.280, P < .001) and negatively with breastfeeding duration (r = -0.468, P < .001). Consumption of added sugars was a significant predictor of rapid weight gain when breastfeeding duration was short (<12 months, β = 0.020, P = .029), but not long (≥12 months, β = 0.001, P = .875).
A high intake of added sugars in individuals below age 2 associates with rapid weight gain, though breastfeeding ≥12 months appears protective against this. Further studies are necessary to substantiate these findings and provide insight into underlying mechanisms.
添加糖的摄入与老年人群的肥胖超标有关，并且母乳喂养已被证明可预防后期肥胖。
本研究旨在确定添加糖的摄入量是否与2岁以下个体的体重快速增加相关，添加糖的摄入量是否与母乳喂养持续时间相关，以及二者如何影响体重。
对141名婴儿/幼儿（年龄11.9±1.9个月，44.7%为男性）收集的三次24小时饮食回忆数据进行横断面分析。多变量回归评估了添加糖摄入量、母乳喂养持续时间和体重状况之间的关系。分层回归通过添加糖*母乳喂养持续时间的相互作用，检验了在体重快速增加（具体而言，年龄别体重百分位数[WFA%tile]上升）中所占的额外方差。
添加糖与WFA%tile上升呈正相关（r = 0.280，P <.001），与母乳喂养持续时间呈负相关（r = -0.468，P <.001）。当母乳喂养持续时间较短（<12个月，β = 0.020，P = 0.029）时，添加糖的摄入是体重快速增加的显著预测因素，但在母乳喂养持续时间较长（≥12个月，β = 0.001，P = 0.875）时则不然。
2岁以下个体高添加糖摄入量与体重快速增加相关，不过母乳喂养≥12个月似乎可对此起到保护作用。需要进一步研究来证实这些发现并深入了解潜在机制。
