Association between the Mediterranean Diet Score and Healthy Life Expectancy: A Global Comparative Study.

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 (ß=0.906 [95% confidence interval, 0.065-1.747], p=0.037) and HALE (ß=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.

Traditional Japanese Diet Score - Association with Obesity, Incidence of Ischemic Heart Disease, and Healthy Life Expectancy in a Global Comparative Study.

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 (ß±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.

Binding of chlorpromazine, phenytoin and aspirin to the erythrocytes and lipoproteins in whole human blood.

The quantitative binding of 14C-labelled chlorpromazine, phenytoin or aspirin (at 10 microM) to blood cells and plasma lipoproteins in whole human blood or to the washed erythrocytes in an isotonic protein-free medium has been studied. The fractions of chlorpromazine, phenytoin and aspirin bound to the blood cells in whole blood amounted to about 40, 14 and 2% of the total amount added, and those to the lipoproteins amounted to 7, 2 and 1%, respectively. Their binding to the washed erythrocytes in protein-free medium was 95, 76 and 40%, respectively. Their octanol:water partition coefficients were 214, 170 and less than 0.1, respectively. These results suggest that the amphiphilic drugs with relatively high hydrophobicity may be bound to the blood cells, mainly to erythrocytes, to considerable extents when administered clinically, and also that their binding to plasma lipoproteins may not be negligible.
