Delayed Eating Schedule Raises Mean Glucose Levels in Young Adult Males: a Randomized Controlled Cross-Over Trial.

Background: Misalignment of meals to the biological clock may cause adverse effects on glucose metabolism. However, the effects of repeated different eating schedules (early compared with late) on glucose concentration throughout the day are poorly understood.

Objectives: We examined the effects of different eating schedules on the 24-h glucose response using a continuous glucose monitor (CGM).

Effects of community-based frailty-preventing intervention on all-cause and cause-specific functional disability in older adults living in rural Japan: A propensity score analysis.

Preventing frailty is crucial in aging societies. We examined the effectiveness of a community-based frailty-prevention program for delaying the onset of functional disability among community-dwelling older adults. From 2014 to 2019, 48 community-based frailty prevention classes (FPC, 60 min/session, once a week), comprising resistance exercise and nutritional or psychosocial programs, were established in Yabu City, Japan.

Analysis method of cellular stress caused by intermediate dose-rate irradiation using a cell lysate array technique.

Ionizing radiation damages DNA and may lead to the development of cancer. Irradiation also generates reactive oxygen species (ROS) which cause damage to various biological molecules. Relatively low dose-rate irradiation causes less damage.

Association of rs174547 Polymorphism with the Composition of Long-Chain Polyunsaturated Fatty Acids in Serum Glycerophospholipids during Pregnancy.

The increase in fetal requirements of long-chain polyunsaturated fatty acids (LCPUFAs) during pregnancy alters maternal fatty acid metabolism, and therefore, fatty acid desaturase () gene polymorphisms may change blood fatty acid composition or concentration differently during pregnancy. We investigated the relationship between a single-nucleotide polymorphism (SNP) and maternal serum LCPUFA levels in Japanese pregnant women during the first and third trimesters and at delivery. Two hundred and fifty-three pregnant women were included, and fatty acid compositions of glycerophospholipids in serum (weight %) and the SNP rs174547 (T/C) were analyzed.

Current status of the rapid decline in renal function due to diabetes mellitus and its associated factors: analysis using the National Database of Health Checkups in Japan.

The increasing number of patients undergoing dialysis due to diabetes mellitus (DM) is causing serious economic problems, and its reduction is an urgent policy issue in developed countries, including Japan. We aimed to assess the association between the annual rapid decline in renal function and health checkup measures, including blood pressure, to identify health guidance targets for preventing diabetic nephropathy (DN) and diabetic kidney disease (DKD) among individuals in a medical checkup system ("Tokuteikenshin" program) in 2018. This longitudinal analysis included 3,673,829 individuals who participated in the "Tokuteikenshin" program in 2018, had hemoglobin A1c (HbA1c) levels ≥5.

Accuracy of breathing and radial pulse assessment by non-medical persons: an observational cross-sectional study.

Early recognition of cardiopulmonary arrest (CPA) expedites emergency calls and resuscitation and improves the survival rate of unresponsive individuals. However, the accuracy of breathing and radial artery pulse assessment by non-medical persons is poorly understood. The aim of this study was to determine the accuracy of breathing assessment and radial pulse palpation among 450 non-medical personnel using a high-fidelity simulator.

Distinct dietary risk factors for incident osteoporotic fractures in early and late postmenopausal phase women.

Introduction: Available evidence on favorable nutritional factors for preventing osteoporosis remains controversial. Considering the recent increases in life expectancy, we investigated the relationship between incident osteoporotic fractures and dietary habits in early and late postmenopausal phase women.

Materials And Methods: Subjects were Japanese postmenopausal outpatients recruited at a primary care institution in Nagano Prefecture (Nagano Cohort Study).

Predictive validity of the Questionnaire for Medical Checkup of Old-Old for functional disability: Using the National Health Insurance Database System.

Aim: To enhance health services that can address multifaceted issues, the Questionnaire for Medical Checkup of Old-Old (QMCOO) was strategically developed to ascertain frailty status. Using the National Health Insurance database system, we aimed to clarify whether the QMCOO can predict new certifications for long-term care for disabilities.

Attitudes toward using "Simple simulator for calculating nutritional food stocks in preparation for large-scale disasters" among local governmental personnel and public health dietitians in Japan: An explanatory mixed methods study.

The Japanese Ministry of Health, Labour and Welfare compiled an Excel sheet - "Simple simulator for calculating nutritional food stocks in preparation for large-scale disasters" (Simulator). We examined the level of recognition and use of the Simulator by local governments and identified the points for its improvement. In stage 1, we surveyed local government personnel who participated in the "Workshop for nutrition assistance during large-scale disasters" held in November 2020 (n = 458; 313 responded) with an online questionnaire on the use of the Simulator and associated issues.

Determinants of Changes in the Diet Quality of Japanese Adults during the Coronavirus Disease 2019 Pandemic.

This study evaluated changes in diet quality during the coronavirus disease 2019 (COVID-19) pandemic and its association with variations in attitudes or behavior, as well as health status changes. Participants were Japanese adults aged 20-69 years who resided in 13 prefectures where specific cautions were announced to prevent the spread of the virus. An online survey was conducted in September 2021, and participants were those who shopped for food or prepared meals more than twice a week during the survey.

Relationship between intra-individual variability in nutrition-related lifestyle behaviors and blood glucose outcomes under free-living conditions in adults without type 2 diabetes.

Creating a Healthy Food Environment as a Radical Population Approach and Japanese Initiatives.

Nutrition education is important to encourage people to promote a healthy diet; however, education alone exerts a limited effect. It is crucial to create a healthy food environment, including food systems that supply diversified, balanced, and healthy food options. Improving the food environment is a population approach.

A Review on Eating Together and Its Health, Diet, and Lifestyle Influences among Japanese.

To discuss the importance associated with eating together for the Japanese population based on recent research evidence, we conducted a systematic review on eating together and eating alone in relation to health, diet, and lifestyle. In this review, we defined "eating together" as eating meals together with other people, not limited to family members but friends, relatives, or neighbors. Articles published between 2000 and 2018 were accessed using domestic and international databases (Igaku Chuo Zasshi, CiNii, J-STAGE, PubMed, Scopus, and Eric).

Developmental trajectories at a high risk for childhood overweight/obesity.

Background: The associations between developmental patterns (trajectories) in children and maternal factors have been widely investigated, but paternal effects on these trajectories are unclear. This study aimed to determine child and parental factors involved in developmental trajectories at high risk for causing adverse cardiovascular (CV) profiles in children.

Methods: We analyzed longitudinal anthropometric data from birth to the present and CV profiles of 1,832 healthy volunteers (51% girls) aged 3-15 years who participated in a nationwide study between July 2012 and January 2014.

Impact of number of functional teeth on independence of Japanese older adults.

Aim: To examine the relationship between the number of present and functional teeth at baseline and future incidence of loss of independence.

Methods: Participants were community-dwelling older individuals who participated in a comprehensive geriatric health examination conducted in Kusatsu town, Japan, between 2009 and 2015. The primary endpoint was the incidence of loss of independence among participants, defined as the first certification of long-term care insurance in Japan.

Variability and Seasonal Change of Urinary Selenium, Molybdenum, and Iodine Excretion in Healthy Young Japanese Adults.

Selenium (Se), molybdenum (Mo), and iodine (I) are essential trace elements or nutrients and their adequate intake is essential for human health. These elements in foods are easily absorbed from the digestive tract and excreted predominantly into the urine, and their nutritional status is reflected in urinary excretion; however, information on the variability of urinary excretion is limited. To characterize the urinary Se, Mo, and I concentrations and their intra- and inter-individual coefficients of variation (CV), correlation, and seasonal change, spot urine samples were collected from 24 healthy university students, 10 males and 14 females, with the mean age of 20.
