This study investigated whether infants' temperament at 18 months is associated with the feeding of foods and drinks that may increase the risk for later obesity.
This was a cross-sectional study of mothers and infants (N = 40 266) participating in the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health. Data were collected by questionnaire. Predictor variables were: infants' temperament at 18 months (internalizing, externalizing, and surgency/extraversion), and mothers' negative affectivity. Outcome variables were feeding of sweet foods, sweet drinks, and night-time caloric drinks at 18 months (all dichotomized). Confounders were child's gender, weight-for-height at 1 year, breastfeeding, and mother's level of education.
After controlling for confounders, infant temperament dimensions at 18 months were significantly associated with mothers' feeding of potentially obesogenic foods and drinks independent of mothers' negative affectivity. Infants who were more internalizing were more likely to be given sweet foods (OR 1.47, CI 1.32-1.65), sweet drinks (OR 1.76, CI 1.56-1.98), and drinks at night (OR 2.91, CI 2.54-3.33); infants who were more externalizing were more likely to be given sweet food (OR 1.53, CI 1.40-1.67) and sweet drinks (OR 1.22, CI 1.11-1.34); and infants who were more surgent were more likely to be given drinks at night (OR 1.66, CI 1.42-1.92).
The association between infant temperament and maternal feeding patterns suggests early mechanisms for later obesity that should be investigated in future studies.
本研究调查了18个月大婴儿的气质类型是否与可能增加日后肥胖风险的食物和饮料喂养有关。
这是一项对参与挪威公共卫生研究所开展的挪威母婴队列研究的母亲和婴儿(N = 40266)进行的横断面研究。通过问卷调查收集数据。预测变量为:18个月大婴儿的气质类型(内化、外化和活泼/外向)以及母亲的消极情感。结果变量为18个月大时甜食、甜饮料和夜间高热量饮料的喂养情况(均进行二分法分类)。混杂因素包括孩子的性别、1岁时的身高体重比、母乳喂养情况以及母亲的教育水平。
在控制混杂因素后,18个月大婴儿的气质维度与母亲喂养可能导致肥胖的食物和饮料显著相关,且与母亲的消极情感无关。内化程度较高的婴儿更有可能被喂食甜食(比值比1.47,可信区间1.32 - 1.65)、甜饮料(比值比1.76,可信区间1.56 - 1.98)以及夜间饮料(比值比2.91,可信区间2.54 - 3.33);外化程度较高的婴儿更有可能被喂食甜食(比值比1.53,可信区间1.40 - 1.67)和甜饮料(比值比1.22,可信区间1.11 - 1.34);活泼程度较高的婴儿更有可能被喂食夜间饮料(比值比1.66,可信区间1.42 - 1.92)。
婴儿气质与母亲喂养模式之间的关联提示了日后肥胖的早期机制,应在未来研究中进行调查。
