ABSTRACT
［Objective］It has been not reported that there is a relationship between health literacy（ HL） and vegetable
intake （VI） in school-children. In the present study, in order to find educational plans to
increase VI, we investigated the relationship between HL related to dietary habit in school-children
and guardians and VI of school-children.
［Methods］The subjects were 314 pairs of fifth and sixth graders and their guardians enrolled in four
elementary schools in Aomori. We conducted a survey using a self-administered questionnaire（ HL,
VI（ servings/d）, and participants’ basic attributes） from January to February 2017 and obtained
responses from 210 pairs. HL related to dietary habit was measured on the “healthy eating literacy
scale”, which was developed specifically for interactive and critical literacy regarding food information
among Japanese adults. The strength of the relationship between HL score and VI of children and
guardians was analyzed by Spearman correlation coefficient in 150 pairs of valid responses.
［Results］The HL score of children and guardians were not significantly associated with children’s VI.
Whereas, there was a significant positive correlation between guardian’s HL score and guardian’s VI
（r＝0.24）. Among the five items constituting HL, a significant relationship was found for the items
“You can choose which food-related information you want from among a plethora of information”（ r＝
0.29）, “You understand food information and telling people”（ r＝0.22）, “You can decide the plan and
action for health improvement based on food information”（ r＝0.20）. There was a significant positive
correlation between children’s and guardian’s HL score （r＝0.24）, and between their VI （r＝0.22）.
［Conclusions］This study is the first to investigate the relationship between children’s and guardian’s HL
and children’s VI, and there was no significant relation between them. Whereas, there was a significant
positive correlation between guardian’s HL score and guardian’s VI. Also, the relationship
between children’s and guardian’s HL score was weak. In this study, it was considered that importance
should be attached to approaches other than HL in order to increase VI by school-children.
