Purpose: The purpose of this study was to explore the correlates of maternal perception (identification and satisfaction) of children’s weight, maternal body shape satisfaction, and maternal feeding styles in Korean preschool-aged children. Methods: A cross-sectional survey design was utilized. Participants consisted of 287 pairs of preschool-aged children (3-6 years) and their mothers. Data were analyzed by |2-test, Fisher’s exact test, ANOVA, and the Pearson correlation coefficient. Results: Among the 287 mothers, 47.7% underestimated their children’s weight, while 15.7% overestimated it. 46.7% of the mothers wished their children weighed more, while 11.1% of them wished their children weighed less. The mean score of maternal body shape satisfaction was 83.75±28.77. The mean score of parent-centered feeding styles was 2.95±0.54, and the mean score of child-centered feeding styles was 3.33±0.42. There were statistically significant correlations between maternal identification of children’s weight and children’s body mass index (BMI) (r=-.366, p<.001). In addition, there were statistically significant correlations between maternal satisfaction of children’s weight and children’s BMI (r=-.484, p<.001), maternal BMI (r=-.126, p=.033), and maternal body shape satisfaction (r=-.127, p=.031). Conclusion: The results of the study suggest that intervention programs for mothers to develop more accurate perception of their child’s weight should be established.
