[Analysis of influential factors of infant acceptance of new complementary food].

Objective: To investigate the process to accept the new complementary food, by infants and to analyze the influential factors.

Method: A total of 105 infants were enrolled in this study. Early infant temperament questionnaires were answered by the mothers. The infants were given 10 times to touch new food (carrot mud), and each of their mealtime score of a 5 degrees system was recorded. The distinctions of the food acceptance were analyzed by using chi-square test. The relations between feeding patterns, sex, maternal parity, education and favor of carrot were analyzed by ANOVA and multivariate correlation analysis respectively.

Result: The infants showed a certain degree of rejection to taste the new food carrot and begin to accept after tasting for several times. By the 5(th) taste the carrot mud was accepted by most infants (87.7%). The breastfed infants were easier to accept the carrot than the formula-fed infants. There was certain degree of difference in accepting the new food between the genders. The male infants were more difficult to accept carrot than female infants. Mother's education level did not affect the baby's acceptance.

Conclusion: Many factors affect the infant's acceptance of new food. Repeatedly tasting new foods will help the infant's acceptance. Infants need at least 5 times of tasting, preferably more than 10 times, to accept new food. Attention should be paid to increase the infant's early experience on the new food. Further research should explore whether the effects of food on the early formation of the picky eating behavior of children.
