Evaluation of dietary behaviors of preschool children in Seoul and Gyeonggi-do associated with the level of parents' health consciousness: using nutrition quotient for preschoolers (NQ-P).

Background/objectives: This study aimed to assess the dietary behaviors of preschool children using the nutrition quotient for preschoolers (NQ-P) and analyzed the difference in the scores of the children's dietary behaviors in regards to the parents' health consciousness.

Subjects/methods: The subjects were 257 children aged 3-5 years and their parents residing in Seoul and Gyeonggi-do, South Korea. The questionnaire is composed of demographic characteristics, the NQ-P questions, and health consciousness. All data were statistically analyzed by SPSS program (ver. 25.0) and the statistical differences in variables were evaluated by χ test, Fisher's exact test, t-test, 1-way analysis of variance and Tukey's multiple comparison test.

Results: There was a significant difference on the intake frequency of processed meat by region and fast foods by age, region, and weight status ( < 0.05). There was also a significant difference in not moving around while eating by weight status and parents' effort to have healthy eating habits by sex ( < 0.05). The mean score of NQ-P of the total subjects was 59.47, which was within the medium-low grade. The mean score of balance was 61.62, and the boys were significantly higher than girls ( < 0.05). As the age of children increased, the mean score of the moderation was significantly decreased ( < 0.05). The scores of NQ-P ( < 0.05), balance ( < 0.01), and environment ( < 0.05) were significantly higher in the high group of parents' health consciousness than the low group.

Conclusions: According to the results of the evaluation by NQ-P, the dietary behaviors of preschoolers residing in Seoul and Gyeonggi-do need to be improved. For improving their eating behavior and nutritional health status, parents and children need customized nutrition education programs based on sex, age, region and weight status of preschool children as well as the degree of parents' health consciousness.
