Dietary intake of adequate quality and quantity in early life is essential for healthy growth and development. This study aimed to examine the association between one-year change in growth and diet quality in preschool children in Adachi City, Tokyo, Japan. A total of 110 participants (49% boys, four to five years old at baseline) were included in this analysis. Body mass index for age z-score (BAZ) and height for age z-score (HAZ) were calculated in accordance with WHO reference. Dietary intakes were assessed using the brief-type self-administered diet history questionnaire for children (BDHQ3y), and daily quality score was calculated based on the Japanese Food Guide Spinning Top (JFGST score). Regression analyses found no significant association between one-year change in growth and diet quality (compared to a low JFGST score, BAZ: β = 0.16, 95% CI: -0.29 to 0.60 for a middle JFGST score, β = -0.14, 95% CI: -0.61 to 0.33 for a high JFGST score, HAZ: β = -0.15, 95% CI: -0.50 to 0.21 for a middle JFGST score, β = -0.06, 95% CI: -0.43 to 0.30 for a high JFGST score). Further studies are needed to develop an appropriate diet quality index for healthy growth in Japanese preschool children.

Background And Objectives: This cross-sectional study aimed to examine associations between diet quality scores and adverse cardiometabolic status in young Japanese women.
Methods And Study Design: In total, 1084 female dietetics students aged 18-22 years completed a validated self-administered diet history questionnaire. Diet quality was assessed using the Diet Quality Score for Japanese (DQSJ), Healthy Eating Index-2015 (HEI-2015), Alternate Healthy Eating Index-2010 (AHEI-2010), Alternate Mediterranean Diet score (AMED), Dietary Approaches to Stop Hypertension score (DASH), and Japanese Food Guide Spinning Top score (JFGST).

Background: Few studies have explored optimal diet quality scores in Japan.
Objectives: We developed a Diet Quality Score for Japanese (DQSJ) and examined the associations of DQSJ and existing diet quality scores with inadequacy of nutrient intake in Japanese adults.
Methods: Candidate components of the DQSJ were extracted from well-established diet quality scores: Healthy Eating Index-2015 (HEI-2015), Alternate Healthy Eating Index-2010 (AHEI-2010), Alternate Mediterranean Diet score (AMED), and Dietary Approaches to Stop Hypertension (DASH).

While late chronotype and greater social jetlag have been associated with poor dietary behavior among the general population, these associations have not been investigated among workers, who struggle to align their sleep timings with work schedules. We aimed to explore the cross-sectional association of social jetlag and a late chronotype with adherence to a healthy diet among Japanese workers. Participants were 1,435 non-shift workers (18-78 years) who attended a nutritional survey.

The Japanese Food Guide Spinning Top (JFGST) indicates optimal intake of five food groups (grain, fish and meat, vegetables, milk, and fruits) and sugar and confectionaries. We aimed to investigate whether adherence to the JFGST in 8th grade junior high school students ( = 3162) was associated with cardiometabolic risks and how different scorings of the JFGST influenced the associations. Metabolic risks were assessed from anthropometrics, blood pressure measurements, and blood glucose and lipid profile measurements.

Objective: Diet quality indices reflect overall dietary patterns better than single nutrients or food groups. Focusing on the needs of children, this study developed a measure of adherence to the Japanese Food Guide Spinning Top (JFGST), which was developed by the Ministry of Health, Labour and Welfare and Ministry of Agriculture, Forestry and Fisheries, Japan, and determined the correlation between index scores and nutrient intake.
Research Methods And Procedures: This cross-sectional study was conducted among 48 children between six and nine years of age from a coastal town in the Kinki region of Japan.
