This study was conducted in order to investigate children's Nutrition Quotient (NQ) and the degree of keeping the Dietary Guidelines of children and their mothers and to further examine the relationships between children and mothers.
The subjects were 281 children from 4th to 6th grade in an elementary school located in Gwangju and their mothers
NQ of the children was 66.8 +/- 14.2, which was in the third (medium) grade. Among the five factors, the scores for Moderation and Diversity were in the second (high) grade, but those for Regularity, Practice, and Balance were in the third grade. Children of non-working mothers had significantly higher scores for NQ and Balance than those of working mothers. Children of mothers with age over 40 had a significantly higher score on Diversity than those with mothers under age 40. Children of mothers with higher education showed higher score for Regularity than those with lower education. Children from high-income families had higher score for Moderation. The score for children keeping the Dietary Guidelines was 78.8 +/- 10.5 and children of non-working mothers showed higher score than those of working mothers. The score for mothers practicing the Dietary Guidelines was 80.6 +/- 9.4 and non-working mothers and mothers with age over 40 had higher score. Children's NQ showed significant correlation with the score for keeping the Dietary Guidelines for children (r = 0.789, p < 0.001) and also with that of mothers (r = 0.235, p < 0.001).
These results show that NQ of elementary school children in Gwangju is in the medium grade, the degree of practicing the Dietary Guidelines for children is pretty fair, and these factors are influenced by their mother's socioeconomic characteristics such as employment, age, education, and family income.
