Association between Dietary Consumption of Meals Combining the Five Food Groups and Stage of Change in the Fifth and Sixth Elementary and Junior High School-Aged Children in Sports Clubs: A Cross-Sectional Research at Soccer Clubs

抄録

This study examined the relationship between dietary intake and stage of change for “combining the five food groups” (grains, fish and meat, vegetables, milk, and fruits) and examined characteristics of dietary intake by stage of change among fifth and sixth graders in elementary and junior high school in sports clubs. The 395 children who completed the self-reported dietary consumption form and questionnaire on stage of change for combining the five food groups were analyzed. Logistic regression analysis was conducted to analyze the relationship between intake of the combined five food groups and stage of change, with frequency of the five meals as dependent variable and stage of change as independent variable. Compared to the precontemplation stage, action (A) and maintenance stages (M) were associated with a higher frequency of the number of meals combining the five food groups (A, stage adjusted odds ratio [AOR]: 5.11, 95% confidence interval (CI): 1.50–17.36, p=0.009; M, AOR: 3.84, 95%CI: 1.58–9.33, p=0.003). In breakfast, the number of and each of combining the five food groups meal, and in dinner, the number of combining the five food groups meal, vegetable dishes and fruits were significantly higher in the A and M than in the pre-action stages. These findings suggest that the number of times meals combining the five food groups are consumed was associated with stage of change while breakfast and dinner showed differences in meal consumption between stages in the fifth and sixth grades elementary and junior high school students belonging to sports clubs.
