Objective To investigate the association between pattern and duration of breastfeeding and fruit and vegetables intake in preschool children,in order to provide a scientific support to guide infant feeding. Methods A secondary analysis was conducted using baseline data from a former non-randomized trial.Information on infant feeding and current situation were collected in questionnaire filled by parents.The associations between duration of breastfeeding and exclusive breastfeeding and consumption of fruit and vegetables were tested by a logistic regression model. Results During 1 189 children in the research,17.1% children had exclusive breastfeeding for more than 6 months and 9.6% children had breastfeeding duration lasting for more than 12 months.There was lower prevalence of overweight and obesity in exclusive breastfeeding duration for more than 6 months group than that less than 6 months group(2.2% & 3.7%,P<0.05).Approximately 87.5% and 67.7% of children consumed fruits and vegetables,respectively,six or more times a week.Consumption of vegetables among preschool children was higher in children who were breastfed for 12 months or longer (OR=1.251; 95%CI:1.115~2.563).Meanwhile,exclusive breastfeeding duration for more than 6 months had a significant association with consumption of vegetables (OR=1.015 ;95%CI:1.002~1.105)after adjusting children gender,age,parents' BMI and etc.There were no relationship between any breastfeeding mode and fruit intake consumption in preschool time(OR=0.882;95%CI:0.412~1.514) &(OR=0.657;95%CI:0.442~1.019). Conclusions Longer duration of breastfeeding and exclusive breastfeeding duration are positively associated with consumption of vegetables in preschool children;However,there is no association with consumption of fruits.It is important for feeding pattern in early life as for which influence the nutrition habit and the growth of children during later life,so the awareness and support for breastfeeding in community and family should further deepened and improved.
