Abstract: Objective To explore the differences in feeding behaviors between grandparents and parents, and to analyze its correlation with preschoolers′ eating behaviors, so as to further clarify the possible influence of caregivers′ identity and feeding behaviors on eating behaviors. Methods From May 2020 to January 2021, a survey was conducted among primary caregivers of preschoolers from 8 kindergartens and 2 community health service centers in Pudong New Area, Shanghai.The propensity score matching with a ratio of 1∶2 was used to form the grandparents group (n=72) and the parents group (n=144) according to primary caregivers′ identity. Results There were statistically significant differences between grandparents and parents in content-restricted feeding (t=4.72, P＜0.001), behavior-restricted feeding (t=2.13, P=0.036), children′s initiative eating (t=-4.76, P＜0.001), exogenous eating (t=-5.07, P＜0.001) and emotional eating (t=1.99, P=0.050).Multivariate analysis of variance (MANOVA) showed that behavior-restricted feeding (F=1.82,P=0.086), encouraging healthy eating (F=2.46,P=0.019) and content-restricted feeding (F=3.69,P=0.001) had significant predictive effects on eating behaviors.There was no statistical correlation between primary caregivers′ identity and eating behaviors of preschoolers (P＞0.10). Conclusions Parents use content-restricted feeding and behavior-restricted feeding more frequently than grandparents.Primary caregivers′ feeding behaviors, rather than their identity, are significantly related to eating behaviors of preschoolers.
