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.
