Abstract

<p>Objective: This study examined the relationship between the Skin Carotenoid (SC) score and the number of vegetables dishes consumed to use the former in nutrition education in Japan.</p><p>Methods: From June to November 2020, 551 people from 19 facilities in Japan conducted SC score measurement and questionnaire surveys. SC score was compared by attribute and food intake status using t-test and one-way analysis of variance. The relationship between the SC score and the number of vegetables dishes was examined by simple regression analysis.</p><p>Results: This study included 520 subjects (analytic rate 94.4%). The average SC score (standard deviation) was 377 (109). The SC score was higher among those who consumed more vegetable dishes, females, people in their 60s or older, non-smokers, and those who consumed fruit, vegetable juice, green juice, and supplements. As a result of simple regression analysis, the SC score increased as the number of vegetable dishes consumed increased (p < 0.001). The regression equation was "SC score = 22.6 × the average number of vegetable dishes consumed + 324." Despite adjusting for attributes and non-vegetable food intake, the number of vegetable dishes affected the SC score (p < 0.001).</p><p>Conclusion: The higher the SC score indicates that more vegetables were eaten. This suggests that SC score can be used as an indicator of vegetable intake. The regression equation allows the number of vegetable dishes using the SC score to be estimated. It is expected that SC score can be used in nutrition education in the future.</p>
