Objective To analyze the rate of unhealthy dietary patterns and eating behavior in preschool children in Yangzhou,and to explore the effect on children′s body mass index(BMI). Methods Totally 2 531 preschool children from 7 nurseries in Yangzhou were enrolled in this study from April to May, 2015,and were assessed by questionnaire survey to collect basic information,dietary patterns and eating behaviors of children over the past week. Results The rate of unhealthy dietary patterns was 7.8%,and the rate of picky eating was the highest (25.2%,637/2 531) among unhealthy eating behaviors,followed by fast eating (18.8%,477/2 531).Moreover,the rates of picky eating and fast eating in boys were significantly higher than those in girls(picky eating:27.5% vs. 22.5%,fast eating:20.9% vs. 16.5%,P<0.05). Multivariate Logistic regression analysis found that preference to salty food(OR=2.05,95%CI:1.26—3.34) and greasy food(OR=1.96,95%CI:1.22—3.16) were risk factors and slow eating(OR=0.31,95%CI:0.23—0.42) was a protective factor for childhood obesity(P＜0.001). However,there was no significant difference on the body weight in preschool children with different dietary patterns(P＞0.05). Conclusions Unhealthy eating behaviors and dietary patterns are prevalent among preschool children in Yangzhou,and unhealthy eating behaviors are related to children′s obesity. So it is suggested to take comprehensive intervention measures,such as controlling family′s unhealthy eating behavior,so as to reduce childhood overweight and obesity.
