Abstract: Objective s To analyze the impact of maternal misperceptions of their preschool child's weight status on their feeding practice,and to provide theoretical support for new interventions regarding parents to take reasonable feeding practices. Methods A cross-sectional survey of 250 mothers of preschool-aged children from two kindergartens at Pudong new area of Shanghai was conducted by using the questionnaire,which included social-demographic characteristics,perceived weight status of child and maternal feeding practice. Results 53.54% of the investigated mothers perceived their child's weight status correctly,and mothers who underestimated their children's weight status were much more than those who overestimated the weight status.In the group of normal-weight children,mothers who perceived their child's weight correctly were more likely to concern about children weight (t=3.793,P=0.000,β=0.435);In the group of overweight children,mothers who underestimated their child's weight status were unlikely to concern about their child's weight,and were more likely to force their child to eat instead of monitoring their child's eating (concern about overweight,t=2.823,P=0.008,β=0.681;monitoring,t=2.142,P=0.039,β=0.539;pressure to eat,t=-2.006,P=0.052,β=-0.376). Conclusions The accuracy of mothers' perceptions of their child's weight status is poor,and a tendency to underestimation of the preschool child's weight status is identified.Maternal misperceptions of their child's weight status might cause mothers to take improper feeding practice.
