Abstract
BACKGROUND Reducing the environmental impact of the food supply is important for achieving Sustainable Development Goals (SDGs) worldwide. Previously, we developed the Traditional Japanese Diet Score (TJDS) and reported in a global ecological study that the Japanese diet is associated with reducing obesity and extending healthy life expectancy etc. We then examined the relationship between the TJDS and environmental indicators. METHODS The average food (g/day/capita) and energy supplies (kcal/day/capita) by country were obtained from the Food and Agriculture Organization of the United Nations Statistics Division database. The TJDS was calculated from eight food groups (beneficial food components in the Japanese diet: rice, fish, soybeans, vegetables, and eggs; food components that are relatively unused in the traditional Japanese diet: wheat, milk, and red meat) by country using tertiles, and calculated the total score from - 8 to 8, with higher scores meaning greater adherence to the TJDS. We used Land Use (m2), Greenhouse gas (GHG) emissions 2007/2013 (kg CO2eq), Acidifying emissions (g SO2eq), Eutrophying emissions (g PO43- eq), Freshwater (L), and water use (L) per food weight by Poore et al. as the environmental indicators and multiplied these indicators by each country's average food supply. We evaluated the cross-sectional and longitudinal associations between the TJDS and environmental indicators from 2010 to 2020. This study included 151 countries with populations ≥ 1 million. RESULTS Land use (β ± standard error; -0.623 ± 0.161, p < 0.001), GHG 2007 (-0.149 ± 0.057, p < 0.05), GHG 2013 (-0.183 ± 0.066, p < 0.01), Acidifying (-1.111 ± 0.369, p < 0.01), and Water use (-405.903 ± 101.416, p < 0.001) were negatively associated with TJDS, and Freshwater (45.116 ± 7.866, p < 0.001) was positively associated with TJDS after controlling for energy supply and latitude in 2010. In the longitudinal analysis, Land Use (β ± standard error; -0.116 ± 0.027, p < 0.001), GHG 2007 (-0.040 ± 0.010, p < 0.001), GHG 2013 (-0.048 ± 0.011, p < 0.001), Acidifying (-0.280 ± 0.064, p < 0.001), Eutrophying (-0.132 ± 0.062, p < 0.05), and Water use (-118.246 ± 22.826, p < 0.001) were negatively associated with TJDS after controlling for confounders. CONCLUSIONS This ecological study suggests that the traditional Japanese dietary pattern might improve SDGs except Fresh water.

Abstract
OBJECTIVE Studies conducted on Japanese people have suggested that a traditional Japanese diet contributes to good health, longevity, and protection against several non-communicable diseases. However, it is unknown whether traditional Japanese dietary patterns are associated with all-cause mortality, cardiovascular disease, and cancer mortality globally. The purpose of this cross-sectional and longitudinal ecological study is to clarify the global association between the traditional Japanese diet score (TJDS) and all-cause, cardiovascular disease, and total cancer mortality. METHODS Data on food supply and all-cause mortality, cardiovascular disease mortality, total cancer mortality, and covariables by country were obtained from a relevant internationally available database. TJDS by country was calculated from eight food groups and the total score ranged from -8 to 8, with higher scores indicating greater adherence to a traditional Japanese diet. We evaluated the cross-sectional and 10-year longitudinal association between TJDS and all-cause, cardiovascular disease, and total cancer mortality using 2009 as the baseline in 142 countries with populations of more than one million. A cross-sectional analysis and a longitudinal analysis were performed using three general linear models or three linear mixed models with different covariables. RESULTS In cross-sectional models controlled for fully-adjusted covariables, TJDS was negatively associated with all-cause mortality (β ± standard error; -43.819 ± 11.741, p < 0.001), cardiovascular disease mortality (-22.395 ± 4.638, p < 0.001), and total cancer mortality (-3.893 ± 1.048, p < 0.001). In 10-year longitudinal models controlled for fully-adjusted covariables, TJDS was significantly negatively associated with all-cause mortality (-31.563 ± 7.695, p < 0.001), cardiovascular disease mortality (-16.249 ± 4.054, p < 0.001), and total cancer mortality (-3.499 ± 0.867, p < 0.001). CONCLUSIONS This cross-sectional and longitudinal ecological study suggests that the traditional Japanese diet is associated with lower all-cause mortality, cardiovascular disease mortality, and total cancer mortality, worldwide.

Abstract
The relationship between egg consumption and ischemic heart disease (IHD) remains controversial as there is still no clear answer regarding the relationship, with research limited to a few geographical regions. In the current study, we conducted a longitudinal analysis of the association between egg intake and IHD incidence (IHDi) and mortality (IHDd) using 28 years of international data from 1990 to 2018. Egg intake (g/day/capita) by country was obtained from the Global Dietary Database. Age-standard IHDi and IHDd rates per 100,000 subjects in each country were obtained from the 2019 Global Burden of Disease database. The analysis included a total of 142 countries with populations of at least one million, for which all data were available from 1990 to 2018. Eggs are consumed worldwide, and regional differences in consumption are also shown. Utilizing IHDi and IHDd as objective variables and egg intake as an explanatory variable, the analysis was conducted using linear mixed models, which controlled for inter- and intra-country variation from year to year. The results showed a significant negative association between egg intake, and IHDi (-0.253 ± 0.117, p < 0.05) and IHDd (-0.359 ± 0.137, p < 0.05). The analysis was carried out using R 4.0.5. The results suggest that adequate egg intake might suppress IHDi and IHDd on a global scale.

Abstract
OBJECTIVES Extending healthy life expectancy (HALE), defined as the average number of years that a person can expect to live in "full health" by taking into account years lived in less than full health due to disease and/or injury, is a common topic worldwide. This study aims to clarify the relationships between the Mediterranean diet score (MDS) and life expectancy (LE) and HALE globally using publicly available international data. SETTING Analyses were conducted on 130 countries with populations of 1 million or more for which all data were available. Individual countries were scored from 0 to 9 to indicate adherence to the Mediterranean diet according to the MDS scoring method. The supply of vegetables, legumes, fruits and nuts, cereals, fish, and olive oil per 1,000 kcal per country was calculated based on the Food and Agriculture Organization Corporate Statistical Database, with a score of 1 for above the median and 0 for below. The same method was used to calculate scores of presumed detrimental components (meat and dairy), with consumption below the median given a value of 1, and consumption above the median given a value of 0. For ethanol, a score of 1 was given for 10g to 50 g of consumption. We investigated the cross-sectional associations between the MDS and LE and HALE at birth in 2009, and the longitudinal associations between the MDS in 2009 and LE and HALE between 2009 and 2019, controlling for covariates at baseline using linear mixed models. RESULTS In the cross-sectional analysis, the MDS was significantly positively associated with LE (β=0.906 [95% confidence interval, 0.065-1.747], p=0.037) and HALE (β=0.875 [0.207-1.544], p=0.011) after controlling for all covariates. The longitudinal analysis also revealed significantly positive associations between the MDS and LE (0.621 [0.063-1.178], p=0.030) and HALE (0.694 [0.227-1.161], p=0.004) after controlling for all covariates. CONCLUSION The present study, based on an analysis using 10 years of international data, showed that countries with a higher MDS showed a positive association with HALE.

Abstract
Abstract
Background
Traditional Japanese diets are considered to be health and longevity. We created a Traditional Japanese Diet Score (TJDS) and investigated the relationship between the TJDS and healthy life expectancy (HALE) longitudinally using global database.
Methods
Average food (g/day/capita) and energy supply (kcal/day/capita) by countries were identified by the Food and Agriculture Organization of the United Nations Statistics Division database. The sum of characterizing traditional Japanese foods supply (beneficial food components in Japanese diet; rice, fish, soybeans, vegetables, eggs, seaweeds, food components not use so much in Japanese diet; wheat, milk, and red meat) were divided as tertile (beneficial food components;-1, 0, 1, not use so much food components; 1, 0, -1). HALE values by country were derived from the Global Burden of Disease 2017 database. The longitudinal effects of TJDS on the rate of change in HALE from 1990 to 2013 were evaluated using a generalized mixed-effect model (GLMM), which takes into account the dependence of repeated observations within countries. The interaction between TJDS and survey year was applied to access the effects on HALE. This study covered 137 countries with populations of 1 million or greater.
Results
Longitudinal analysis controlled for covariates showed that smooth term of the interaction between TJDS and survey year was significant (p < 0.001). The TJDS was negative associated with HALE in 1990, and in 1991, but positive associated after 2002.
Conclusions
The relationship between the TJDS as a healthy eating style and HALE is getting stronger since the 21st century.
Key messages
Well-balanced eating habits of traditional Japanese diets is supports healthy life expectancy.

Abstract
Abstract
Background
This longitudinal ecological study was conducted to determine the global trends in the age-standardised prevalence of type 2 diabetes mellitus (T2DM) and its association with socioeconomic, lifestyle and health indicators.
Methods
Data pertaining to the age-standardised prevalence of T2DM (rates per 100,000) and socioeconomic, lifestyle and health indicators were obtained from several international databases. Data available from 1990 to 2017 for 139 countries with populations of 1 million or greater were analysed, followed by estimation of slopes for T2DM prevalence in each country. The longitudinal association between T2DM and the standardised variables of socioeconomic, lifestyle and health indicators was fitted using a generalised linear mixed-effects model with random intercept for each country and random slope for year.
Results
The country-specific age-standardised prevalence of T2DM decreased significantly in 9 countries, remained unchanged in 11 countries and increased significantly in 119 countries. The estimated standardised effect of age-standardised education for T2DM was the largest at − 524.5 (SE; 109.9), followed by − 514.8 (SE; 95.6) for physical activity and 398.8 (SE; 45.8) for body mass index (BMI) (P < 0.0001 for all).
Conclusions
The factors strongly associated with global T2DM prevalence and trends were years of education, followed by physical activity and BMI. This study also provides a basis for investigating public health approaches to control the increase in global T2DM prevalence.
Key messages
The promotion of policies that reduce international educational disparities may have the potential to reduce the global increase in the number of patients with T2DM.

Abstract
Abstract
Background
Folate deficiency increases serum homocysteine and may cause cognitive impairment. However, there have been no international longitudinal studies that examined the association between folic acid intake and dementia. We investigated the longitudinal association between folate intake and the prevalence of dementia using global data during 27 years.
Methods
Prevalence of Alzheimer’s disease and other dementias and folic acid intake by country were obtained from the Global Burden of Disease (GBD) 2017 database. The longitudinal associations between folic acid intake and prevalence of dementia was examined using linear mixed effect model during 27 years from 1990 to 2017 in 151countries with populations of 1 million or greater. The effects of folic acid, year and interaction of folic acid and year were estimated controlling for covariates including socio-economic variables and life-style variables.
Results
Fixed effects of folic acid was highly significant (mean and SE; -33.1±7.1, p < 0.001) and interaction of folic acid and survey year was also significant (0.90±0.13, p < 0.001). Slope of folic acid for dementia prevalence was significant in 1990 and the slope has decreased with the year and has become not significant after 2011.
Conclusions
Folic acid was associated with the prevalence of dementia, but weakened over the years.
Key messages
Although folic acid intake has been associated with the of dementia, the risk of dementia may be increasingly related to factors other than nutrition.

Abstract
Abstract
Background
Traditional Japanese diets are considered to be one cause of Japanese health and longevity. We created a Traditional Japanese Diet Score (TJDS) and investigated the relationship between the TJDS and cancer during more than 20 years using global database.
Methods
Total cancer incidence and mortality by country were identified from the Global Burden of Disease 2017 database. Average food supply (g/day/capita) and energy supply (kcal/day/capita) by country were obtained from the Food and Agriculture Organization of the United Nations database. The TJDS by country was calculated from nine food groups, the higher scores mean the more adherence to traditional Japanese diet. That is beneficial food groups (rice, fish, soybeans, vegetables, eggs, seaweed) gave positive points to high supply amount, and food groups not commonly used in the Japanese diet (wheat, milk, and red meat) gave minus points to high supply amount. The longitudinal associations between the TJDS and cancer incidence and mortality controlled for covariates were examined during 23 years from 1990 to 2013. The country covered by this study was 139 countries with populations of 1 million or greater.
Results
The TJDS was negatively associated with cancer incidence and mortality longitudinally in a linear mixed-effect model controlled for covariates.
Conclusions
These results suggest that greater adherence with the TJDS supressed cancer incidence and mortality worldwide.
Key messages
Well-balanced eating habits like traditional Japanese diets is important for suppressing cancer.

Abstract
BACKGROUND The purpose of this study was to clarify the global relationship between the Mediterranean diet score (MDS) and country-wise incidence and mortality of ischaemic heart disease (IHD) using an international database. METHODS We used population data from a global longitudinal database covering 137 countries with a population of over one million. MDS were evaluated based on the total score of the nine foods that comprise the Mediterranean diet. The incidence and mortality of IHD by country was derived from the Global Burden of Disease (GBD) database. Average food (g/day/capita) and energy supply (kcal/day/capita) by country, excluding loss between production and household, were obtained from the Food and Agriculture Organization of the United Nations Statistics Division database. Data from the GBD database were used for body mass index, current smoking rates, physical activity, years of education and percentage of the Muslim population. We identified the percentage of the population over 65 years of age (aging rate) and gross domestic product per capita (US$/capita) using the World Bank database. A linear mixed-effect model was used for evaluating the effects of MDS on incidence and mortality of IHD controlled for socioeconomic and lifestyle variables. RESULTS Analysis showed that MDS was significantly associated with IHD incidence after controlling for covariates (-1.01 ± 0.27, P < 0.001). Similarly, there was a significant association between MDS and IHD-related mortality after controlling for covariates (-0.73 ± 0.34, P < 0.05). CONCLUSION Analysis of 27 years of data suggests that a Mediterranean diet might have a preventive effect on IHD.

Abstract
Background There is a need for global public health strategies to effectively curb the ever-growing global diabetes population. This longitudinal ecological study was conducted to elucidate the country-specific trends of the age-standardised prevalence of type 2 diabetes mellitus (T2DM) and their association with socioeconomic, lifestyle and health indicators. Methods Data pertaining to the age-standardised prevalence of T2DM (rates per 100 000) and socioeconomic, lifestyle and health indicators were obtained from several international databases. Data available from 1990 to 2017 for 139 countries with populations of 1 million or greater were analysed, followed by estimation of slopes for T2DM prevalence in each country. The longitudinal association between T2DM and the standardised variables of socioeconomic, lifestyle and health indicators was fitted using a generalised linear mixed-effects model with random intercept for each country and random slope for year. Results The country-specific age-standardised prevalence of T2DM decreased significantly in 9 countries, remained unchanged in 11 countries and increased significantly in 119 countries. The estimated standardised effect of age-standardised education for T2DM was the largest at −524.5 (SE; 109.9), followed by −514.8 (SE; 95.6) for physical activity and 398.8 (SE; 45.8) for body mass index (BMI) (P < 0.0001 for all). Conclusions The factors largely associated with global T2DM prevalence and trends were years of education, followed by physical activity and BMI. This study also provides basic resources for examining public health approaches to curb the increase in global T2DM prevalence.

Abstract
BACKGROUND The traditional Japanese diet is considered one of the important factors of health and longevity in Japanese people. Breast cancer is the most common cancer among women in the world. However, the association between the traditional Japanese diet and breast cancer is unclear. The purpose of this study was to investigate the longitudinal association between the traditional Japanese diet score (TJDS) with the incidence and mortality of breast cancer in an ecological study. METHODS Food supply and breast cancer incidence and mortality by country were obtained from an international database. TJDS by country was calculated from nine food groups and the total score ranged from -9 to 9, with higher scores indicating greater adherence to a traditional Japanese diet. Longitudinal associations of interaction between TJDS and fiscal year on breast cancer incidence and mortality were investigated in 139 countries with populations of 1 million or greater. The longitudinal analysis was evaluated using four linear mixed-effect models with different adjustment covariables. RESULTS Many countries with high scores on TJDS had lower distributions of breast cancer incidence and mortality in 1990-2017. Longitudinal analysis using a linear mixed-effect model controlled for socio-economic and lifestyle covariables showed that the interaction between TJDS and fiscal year was significantly associated with incidence of breast cancer (-0.453 ± 0.138, p < 0.01) and mortality of breast cancer (-0.455 ± 0.135, p < 0.001). CONCLUSIONS This longitudinal analysis suggested that a traditional Japanese diet has been associated with lower breast cancer incidence and mortality worldwide in recent years.

Abstract
OBJECTIVES We created a Traditional Japanese Diet Score (TJDS), and to clarify the relationship between TJDS and obesity, ischemic heart disease (IHD), and healthy life expectancy (HALE). DESIGN Ecological study. SETTING Food (g/day/capita) and energy (kcal/day/capita) supply was determined using the Food and Agriculture Organization of the United Nations Statistics Division database. The sum of characteristic traditional Japanese foods (beneficial food components in the Japanese diet: rice, fish, soybeans, vegetables, eggs, and seaweeds; food components rarely used in the Japanese diet: wheat, milk, and red meat) was divided as tertiles (beneficial food components: -1, 0, 1; rarely used food components: 1, 0, -1). Obesity rate was determined using the World Health Organization database. Incidence of IHD, HALE and smoking rate were determined using the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 database. Gross domestic product per capita, percentage of population > 65 years old, and health expenditure were determined using the World Bank database. Education years were obtained from the United Nations Educational, Scientific and Cultural Organization Institute for Statistics. Associations between TJDS and obesity, IHD and HALE were examined in 132 countries with a population of 1 million or greater using a general linear model controlled for co-variables. RESULTS TJDS was distributed from -6 to 7. TJDS was inversely correlated to obesity (β±SE; -0.70±0.19, p<0.001), IHD (-19.4±4.3, p<0.001), and positively correlated to HALE (0.40±0.14, p<0.01). CONCLUSIONS TJDS is a good indicator of a healthy diet, and applies to preventing obesity, IHD and extending HALE.

Abstract
BACKGROUND/OBJECTIVES The prolongation of healthy life expectancy (HALE) is a core issue of health policy in many countries. The purpose of this study is to clarify the relationship between dietary diversity and HALE using international databases. MATERIALS/METHODS HALE data by country were derived from the Global Burden of Disease (GBD) 2015 database. Average food supply (g/day/capita) and energy supply (kcal/day/capita) by country, excluding loss between production and household, were obtained from the Food and Agriculture Organization of the United Nations Statistics Division database. Each food was sorted across 12 food groups, and dietary diversity was obtained from food groups using the Quantitative Index for Dietary Diversity (QUANTIDD). The cross-sectional and longitudinal associations between QUANTIDD and HALE were examined in the countries with populations of one million or greater. RESULTS Cross-sectional analysis showed that HALE was significantly associated with QUANTIDD (β = 99.9 ± 11.4, p < 0.001) in the single regression model and in the multiple regression model controlled for covariates (β = 36.4 ± 11.3, p = 0.002). Longitudinal analysis showed that HALE increased with QUANTIDD during the 15-year study period (β = 46.4 ± 5.1, p < 0.001), and this association was also significant when controlled for covariates (β = 39.7 ± 5.1, p < 0.001). Longitudinal association of QUANTIDD with the percentage difference between life expectancy and HALE controlled for covariates was significantly negative (β = - 1.3 ± 0.5, p = 0.011). CONCLUSIONS After controlling for socioeconomic indicators, longer healthy life is enjoyed by populations of countries with greater dietary diversity.
