Association between feeding practices and weight status in young children

BACKGROUND Inappropriate feeding practices during infancy may lead to overweight. The aims of this study are to investigate the growth of children in the first 18 months of life; to evaluate the feeding practices of caregivers using developed Young Child Feeding Questionnaire; and to investigate caregivers' feeding attitudes and behaviors associated with infants' weight status. METHODS Six month-old infants and their main caregivers entering the Kongjiang Community Health Center for a routine well-child check were recruited for this study and followed up every 6 months for 12 months. Questionnaire survey was carried out through on-site face-to-face interview at each visit with the main caregivers of children using Young Child Feeding Questionnaire, which included caregivers' feeding attitudes and behaviors. The weight and length of children were measured at each visit. RESULTS Among 197 children who completed the investigation at 18 months of age, 64 (32.49%) children were overweight (BMI-for-age z scores > +1). The increases in weight-for-age z scores and BMI-for-age z scores from birth to 6 months, 12 to 18 months and birth to 18 months in overweight children were significantly higher than those in normal weight children (P < 0.001). In normal weight children, caregivers worried more about children's being "underweight" and "eating less" (P = 0.001), whereas caregivers with overweight children worried more about children's "eating too much" and being "overweight" (P < 0.001). In 64 overweight infants, the scores of "concern about child's food intake" were significantly correlated with increase in BAZ between 12 and 18 months (Bata = 0.293, P = 0.029). CONCLUSIONS Young Child Feeding Questionnaire is a valid tool for evaluating feeding practice of caregivers. The rapid BMI gain in overweight children may be associated with some inappropriate feeding attitudes and behaviors of caregivers.
