Background: To decrease mortality, the benefit of combined healthy lifestyles has been suggested but is still unclear, especially for cause-specific mortality. We examined the relationship between combined lifestyle factors and all-cause and cause-specific mortality in Shiga prefecture, Japan. Methods: This was an ecological study of 19 municipalities, using the data from the 2008–2012 standard mortality ratio (SMR) reported by the Ministry of Health and Welfare and the 2015 Health and Nutrition Survey in Shiga prefecture. The health behaviors score was calculated based on five factors (ranging from 0 to 5): diet quality (assessed adherence to dietary reference intake for Japanese), smoking, alcohol drinking, regular exercise, and sleep duration. In the multiple linear regression, the relationships between the health behaviors score and SMR of all-cause, cancer, heart diseases, and cerebrovascular diseases were estimated by sex. Results: The health behaviors score was negatively associated with the cancer SMR in women (β = −0.968, p = 0.011). For other causes, no significant association was found for either sex. A greater proportion of those who never smoked (β = −0.780, p = 0.016) and those who had a higher quality diet (β = −0.703, p = 0.048) were associated with lower cancer SMR in women. Women’s intake of some micronutrients, particularly fruits, was higher than men. This study suggests that a combination of health behaviors, especially never smoking and high-quality diet intake are associated with lower cancer SMR in women and could be helpful in prolonging life expectancy.

Although various factors can reduce the risk of anemia, information on dietary contributions is limited. This study aimed to evaluate the association between anemia and eating patterns in Japanese elderly. Our study included 6,864 elderly individuals, aged ≥65 y, whose data were obtained from the 2010–2015 National Health and Nutritional Survey, Japan. Anemia was defined as whole blood hemoglobin concentrations <13 g/dL in men, and <12 g/dL in women. We classified eating patterns into 33 food groups, using food items obtained from dietary records, and identified three dietary patterns using principal component analysis method. Participants were assigned and divided into quartiles according to pattern-specific factor scores. We calculated adjusted odds ratios (ORs) for anemia using multivariate logistic regression, and assigned the first quartile (minimum) as the reference. The overall prevalence of anemia was 17.1%. The meats and vegetables eating pattern was characterized by red meat and other vegetables, the Japanese eating pattern by rice and salted or pickled vegetables, and the fruits and vegetables eating pattern by fruits and green-yellow vegetables. Participants in the highest meats and vegetables eating pattern quartile had a 20% lower risk of anemia than those in the lowest quartile (OR 0.81; 95% confidence interval (CI) 0.66–1.00); the Japanese eating pattern participants had a 20% higher risk of anemia (OR 1.28; 95% CI 1.06–1.53). The fruits and vegetables eating pattern participants had no significant change in their risk of anemia. This study may indicate that consuming a high red meat diet prevents anemia in elderly Japanese individuals.

    © 2019. All Rights Reserved. Information about an association between animal food intakes and risk of anemia is still limited. This study aimed to investigate the association between fish and meat intake and anemia risk in the Japanese elderly. Methods and Study Design: A nationally representative sample of 6,469 aged 65 years and over was obtained from pooled data of annual National Health and Nutritional Survey in Japan during 2002–2011. Anemia was defined as hemoglobin concentrations <13.0 g/dL in males and <12.0 g/dL in females. Logistic regression analysis, with the lowest intake tertile as the reference, was applied to estimate anemia risk for each nutrient and food group. Results: After adjustment for putative confounding factors, males in the highest tertile of animal protein intake had significantly lower risk of anemia than those in the lowest tertile (odds ratio (OR): 0.77; 95% confidence interval (CI): 0.63, 0.95; p for trend=0.017). These associations were not seen in females (OR: 0.72, 95% CI: 0.49, 1.06; p for trend=0.100). Multivariate analyses revealed that anemia risk (OR: 0.80; 95% CI: 0.65, 0.97; p for trend =0.002) was lower for males in the highest tertile of fish intake than in the lowest tertile; this effect was also observed for females (OR: 0.64; 95% CI: 0.45, 0.92; p for trend =0.014). In both sexes, the highest tertile of meat intake was not associated with lower anemia risk in the multivariate-adjusted models. Conclusions: The current cross-sectional study in Japanese elderly males suggests that higher animal protein, specifically the high protein content of fish may be associated with a lower prevalence of anemia.

    [Abstract]

    © 2018, Center for Academic Publications Japan. All rights reserved. We investigated oral glucose tolerance and tryptophan (Trp) metabolism in non-obese and non-insulin-dependent diabetic Goto–Kakizaki (GK) rats fed high-Trp diets. Five-week-old male Wistar and GK rats were fed a 20% casein diet (control diet) or the same diet supplemented with 1%, 2%, 3%, or 5% Trp for 58 d. Oral glucose tolerance tests were performed on Days 14 and 28 of the experimental period. Urine as well as livers and blood were collected on the last day of the experiment. The glucose concentration and the amount of Trp metabolites were measured. On Day 14 of the experiment, the incremental blood glucose concentrations integrated over a period of 2 h (∆AUC0-2h) of blood glucose in rats fed the 3% and 5% Trp diets had decreased by 13% and 18%, respectively, compared with that of the control-GK rats. However, no significant differences were found in the rats fed +1% or +2% Trp diets compared with control-GK rats. On Day 28, there were no significant differences found in the ∆AUC0-2hof blood glucose levels in any group including the control-GK group. On the last day, the concentrations of plasma glucose, total cholesterol, and triglyceride did not show differences in any group. There were no specific phenomena observed in the metabolism of Trp in GK rats even when fed an excess of Trp, compared with that of Wistar rats. Oral Trp administration and its continuous use may not improve blood glucose levels in type 2 diabetic rats.
