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.

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.

Self-Efficacy of Parents of Boys in Sports Clubs on Meal Preparation and Boys' Dietary Intake: A Cross-Sectional Study of Soccer Clubs.

This study examined the relationship between parents' self-efficacy for preparing meals combining the five food groups (grains, fish and meat, vegetables, milk, and fruits) and the dietary intake of their children who were elementary and junior high school students belonging to a sports club. A total of 365 children completed a self-reported dietary intake form, and their parents completed a questionnaire on self-efficacy for preparing meals combining the five food groups. Logistic regression analysis was conducted to assess the relationship between the children's intake of the combined five food groups and parents' self-efficacy score, with frequency of meals combining the five food groups as the dependent variable and the self-efficacy score as the independent variable. In a multivariate logistic regression analysis that was higher self-efficacy scores were associated with a higher frequency of meals that contained all five food groups, with an odds ratio of 1.06 (95% confidence interval: 1.00-1.12; p=0.036). Significant positive correlations were also found between parents' self-efficacy and the number of times children consumed four food types (fish and meat, vegetables, milk, and fruits) at breakfast and three food types (grains, milk, and fruits) at dinner. These findings suggest that parents' self-efficacy for preparing meals combining the five food groups was associated with the number of meals with all five food groups consumed by their children, who were fifth and sixth graders in elementary and junior high school and belonged to sports clubs.
