目的初步分析母亲对学龄前儿童体重感知偏差对其喂养行为的影响,为今后干预家长采取科学、正确的喂养行为提供一个新途径。方法采用方便抽样,对上海市浦东新区某两所幼儿园250名学龄前儿童的母亲进行问卷调查。调查内容包括人口社会学特征、母亲对子女感知体重水平和母亲的喂养行为。结果 53.54%的母亲能够准确感知子女的体重水平,且低估体重水平者(38.89%)远多于高估体重水平者(7.58%)。在体重水平正常组中,正确评估子女体重水平的家长更可能担心其子女今后体重超重(t=3.793,P<0.001,β=0.435);在体重水平超重组中,低估子女体重水平的家长不太担心子女的体重问题,更可能采取逼迫进食而不是监督饮食的喂养方式(对子女超重的担心:t=2.823,P=0.008,β=0.681;监督饮食:t=2.142,P=0.039,β=0.539;逼迫进食:t=-2.006,P=0.052,β=-0.376)。结论母亲对学龄前儿童的体重水平的感知准确性较差,且有低估儿童体重水平的倾向。母亲对子女体重感知偏差可能会导致其采取不合理的喂养行为。
OBJECTIVE: To analyze the impact of maternal prejudice on the feeding behavior of preschool children, and to provide a new way for parents to take scientific and correct feeding behavior in the future. Methods A sample of 250 preschool-age mothers in two kindergartens in Shanghai’s Pudong New Area was surveyed by means of convenient sampling. The survey included socio-demographic characteristics of the population, mothers’ perceptions of their children’s weight levels, and mother’s feeding practices. Results 53.54% of the mothers were able to accurately detect the weight of their children, and those who underestimated the level of weight (38.89%) were far more than those who overestimated the level of weight (7.58%). In the normal weight group, parents who correctly assessed their children’s weight were more likely to worry about their children being overweight in the future (t = 3.793, P <0.001, β = 0.435); parents who underestimated their weight in the overweight group Too worried about the issue of children’s weight was more likely to adopt forced feeding rather than supervised diet (fear of overweight in children: t = 2.823, P = 0.008, β = 0.681; supervised diet: t = 2.142, P = 0.039, = 0.539; forced eating: t = -2.006, P = 0.052, β = -0.376). Conclusion Mothers are less likely to perceive body weight in preschool children and tend to underestimate children’s body weight. Mothers’ perception of their children’s weight perception may lead to their unreasonable feeding behavior.
