Oral microbiome alpha diversity and all-cause, cardiovascular, and non-cardiovascular mortality in US adults: Evidence from the NHANES 2009-2019.

Background And Aims: Knowledge about the association between oral microbiome diversity within individuals and cardiovascular disease (CVD) and non-CVD mortality is scarce. Besides, variation by sex and racial and ethnic groups, and the potential mediators of these associations remain unclear. We aimed to investigate the associations of oral microbiome alpha diversity with all-cause, CVD, and non-CVD mortality, and the interaction effects of sex and racial and ethnic groups and potential mediators in the associations.

Association of anemia with hyperadiponectinemia in oldest-old Japanese women who resided at home alone without wheelchair use.

The association of anemia with hyperadiponectinemia (HAN) (≥ 20 μg/mL) was studied in 95 Japanese women aged 65-74 (young-old), 175 women aged 75-84 (old-old), and 51 women aged over 85 (oldest-old) who resided at home alone without wheelchair use. The prevalence of anemia was 21.5% overall and increased with aging stepwise (9.

Low muscle mass is associated with low insulin sensitivity, impaired pancreatic β cell function, and high glucose excursion in nondiabetic nonobese Japanese women.

Aim: We tested whether skeletal muscle mass is associated with insulin sensitivity, pancreatic β-cell function, and postglucose glycemia.

Methods: Appendicular skeletal muscle mass (ASM) (relative to body size, %ASM) by DXA, surrogate measures of insulin sensitivity, insulin secretion and the disposition index (insulin sensitivity adjusted insulin secretion: a product of the insulinogenic index and Matsuda insulin sensitivity index) inferred from serum insulin kinetics during a 75 g oral glucose tolerance test (OGTT) were evaluated in 168 young and 65 middle-aged women, whose BMI averaged <23.0 kg/m and HbA1c ≦ 5.

The different associations of serum gamma-glutamyl transferase and alanine aminotransferase with insulin secretion, β-cell function, and insulin resistance in non-obese Japanese.

The present study investigated the associations of serum gamma-glutamyl transferase (GGT), a marker of fatty liver and oxidative stress, and ALT/AST, a marker of fatty liver, with percentage trunk fat and postload glucose, insulin resistance, and β-cell function in middle-aged Japanese individuals, whose BMI averaged < 23.0 kg/m. Pancreatic β-cell function was assessed using the disposition index calculated by a product of the insulinogenic index (IGI) and Matsuda insulin sensitivity index, a biomarker of early-phase glucose-stimulated insulin secretion and whole-body insulin sensitivity, respectively.

Associations of adipose insulin resistance index with pancreatic β cell function (inverse) and glucose excursion (positive) in young Japanese women.

The relationship of adipose tissue insulin resistance (AT-IR, a product of fasting insulin and free fatty acids) and homeostasis-model assessment-insulin resistance (HOMA-IR) to β-cell function was studied cross-sectionally in the setting of subtle glucose dysregulation. Associations of AT-IR and HOMA-IR with fasting and post-glucose glycemia and β-cell function inferred from serum insulin kinetics during a 75 g oral glucose tolerance test were studied in 168 young female Japanese students. β-cell function was evaluated by disposition index calculated as a product of the insulinogenic index (IGI) and Matsuda index.

The association between employee lifestyles and the rates of mental health-related absenteeism and turnover in Japanese companies.

We assessed the association of employee lifestyles (e.g., smoking, exercise, drinking, and sleep habits) with mental health-related absenteeism and turnover rates utilizing data from the annual Health and Productivity Management survey by Japan's Ministry of Economy, Trade and Industry.

Adipose tissue insulin resistance index was inversely associated with gluteofemoral fat and skeletal muscle mass in Japanese women.

Associations of adipose tissue insulin resistance index (AT-IR, a product of fasting insulin and free fatty acids) with body fat mass and distribution and appendicular skeletal muscle mass (ASM) were compared with results of homeostasis-model assessment-insulin resistance (HOMA-IR) in 284 Japanese female university students and 148 their biological mothers whose BMI averaged < 23 kg/m. Although mothers compared with daughters had higher BMI, body fat percentage, trunk fat to body fat (TF/BF) ratio and lower leg fat to body fat (LF/BF), AT-IR and HOMA-IR did not differ. We had multivariable linear regression analyses which included TF/BF ratio, LF/BF ratio, weight-adjusted ASM (%ASM), height-adjusted ASM index (ASMI), fat mass index (FMI), and body fat percentage.

Associations of adipose insulin resistance index with leg (gluteofemoral) fat (inverse) and serum alanine aminotransferase (positive) in young Japanese women.

Aim: Associations of the adipose tissue insulin resistance index (AT-IR, a product of fasting insulin and free fatty acid) with body fat distribution and the ratio of alanine to aspartate aminotransferase (ALT/AST), a marker of hepatosteatosis, were examined in the context of the metabolic syndrome.

Methods: Legs, the trunk and body fat by DXA, blood pressure (BP) and blood chemistry were measured in 284 young Japanese female university students and 148 middle-aged biological mothers whose BMI averaged <23 kg/m.

Results: Young women had higher leg fat/body fat and lower trunk fat/body fat ratio (both p < 0.

[Development of a new method for assessing the availability of low-sodium foods in Japan].

Objectives　Food environment improvement involving salt reduction requires improving access to and labeling low-sodium foods. Assessing the implementation status of these measures is also necessary. However, to date, no established methods exist for assessing the availability of low-sodium foods in communities.

Higher childhood weight gain, lower skeletal muscle mass, and higher cereal consumption in normal-weight Japanese women with high-percentage trunk fat: a subanalysis study.

Normal-weight but high-percentage trunk fat phenotype was characterized in a setting where adiposity is not associated with educational and socioeconomic status. Body size trajectory since birth, current body composition measured using whole-body dual-energy X-ray absorptiometry, cardiometabolic traits, serum adipokines, and dietary intake were measured cross-sectionally in 251 normal weight Japanese female university students whose fasting triglyceride and homeostasis model assessment-insulin resistance (HOMA-IR) averaged 56 mg/dL and 1.2, respectively.

Associations of ALT/AST, a marker of hepatosteatosis, with pulse rate in young women and with blood pressure in middle-aged women independently of abdominal fat accumulation and insulin resistance.

Unlabelled: We examined whether alanine aminotransferase/aspartate aminotransferase (ALT/AST), a marker of hepatosteatosis, may be associated with a wider constellation of variables related to metabolic syndrome in Japanese women. Body fat and distribution, and metabolic syndrome-related variables were measured in 311 young and 148 middle-aged women. We had Pearson's correlation analysis and then stepwise multivariate linear regression analyses.

Mortality from major causes and lifestyles by proportions of public assistance recipients among 47 prefectures in Japan: Ecological panel data analysis from 1999 to 2016.

Objective: Comprehensive investigations of correlations between subnational socioeconomic factors and trends in mortality and lifestyle are important for addressing public health problems.

Methods: Forty-seven prefectures in Japan were divided into quartiles based on the proportion of public assistance recipients (PPAR). Age-standardized mortality from all causes, cancer, heart disease, and stroke in each prefecture were averaged for these quartiles in 2000, 2005, 2010, and 2015.

Associations of Alanine Aminotransferase/Aspartate Aminotransferase, a Marker of Hepatosteatosis, with Adipose Tissue Insulin Resistance Index and Leptin/Adiponectin Ratio in Japanese Women.

We assessed whether alanine aminotransferase/aspartate aminotransferase (ALT/AST), a marker of hepatic steatosis, may be associated with adipose tissue dysfunction more closely than hepatic and muscle insulin resistance (IR). Associations with adipose tissue IR index (AT-IR) calculated as a product of fasting insulin and free fatty acids, leptin/adiponectin ratio, a proxy of adipocyte dysfunction, homeostasis model assessment IR (HOMA-IR), hepatic and muscle IR inferred from plasma insulin kinetics during a 75 grams oral glucose tolerance test (OGTT) were studied in nondiabetic 307 young and 148 middle-aged Japanese women, whose body mass index averaged 20 and 22 kilograms/m, respectively. On multivariate linear regression analysis in young women, ALT/AST was associated with trunk/leg fat ratio (standardized  = 0.

Association between serum leptin concentrations and homeostasis model assessment-insulin resistance of 2.5 and higher in normal weight Japanese women.

Normal weight insulin resistant phenotype was characterized in 251 Japanese female university students using homeostasis model assessment-insulin resistance. Birth weight, body composition at age 20, cardiometabolic traits and dietary intake were compared cross-sectionally between insulin sensitive (< 1.6, n = 194) and insulin resistant (2.
