The purpose of this study was to assess the nutritional status of women university students in the third-grade of a registered dietitian training course, based on the Dietary Reference Intakes for Japanese(2010). We initially selected 46 students, and obtained valid responses from 41 students(89.1%). We performed body measurements, blood tests, a dietary weighing method for 3 days, and the measurement of physical activity by the accelerometer. In regard to the physique and blood test of the subjects, 24.4% were underweight, 4.9% were obese and 20.0% were anemic. The dietary weighing method showed that the rate of women who took vitamin C below the estimated average requirement was 90.0%, that of folic acid, iron and calcium were 41.0%, 83.0%, and 68.0% respectively. While the rate of salt intake greater than the dietary goal (7.5g/day)was 36.5%, the rate of fat energy ratio greater than the dietary goal(30%)was 31.7%. The average number of steps per day was 8,907 ± 2,293. These results showed that there was an overall insufficient intake of total energy, vitamins, and minerals, indicating that further nutritional management for the women students is required

Association of Postbreakfast Triglyceride and Visit-to-Visit Annual Variation of Fasting Plasma Glucose with Progression of Diabetic Nephropathy in Patients with Type 2 Diabetes

Urinary albumin/creatinine ratio (ACR) was measured at baseline and after a median follow-up of 6.0 years in 161 patients with type 2 diabetes. Intrapersonal means and SD of HbA1c, systolic BP, fasting, and postmeal plasma glucose (FPG and PMPG, resp.) and serum triglycerides (FTG and PMTG, resp.) were calculated in each patient during the first 12 months after enrollment. Associations of these variables with nephropathy progression (15 patients with progression of albuminuric stages and 5 with ACR doubling within the microalbuminuric range) were determined by multivariate logistic regression analysis providing odds ratio with 95% confidential interval. Patients with nephropathy progression, compared with those without nephropathy progression, had higher HbA1c (p<0.01). They also had higher means and SD of FPG (both p<0.05), FTG (both p<0.05), and PMTG (p=0.001). Multivariate logistic regression analysis demonstrated that SD-FPG (1.036, 1.001–1.073, p=0.04) and PMTG (1.013, 1.008–1.040, p=0.001) were significant predictors of progression of nephropathy even after adjustment for mean FPG and SD-FTG, age, sex, BMI, waist circumference, diabetes duration and therapy, means and SDs of HbA1c, PPG, FTG and systolic BP, baseline ACR, smoking status, and uses of antihypertensive and lipid-lowering medications. Consistency of glycemic control and management of postmeal TG may be important to prevent nephropathy progression in type 2 diabetic patients

Characteristic dietary habits associated with high values of estimated 24-hours urinary sodium excretion and sodium-to-potassium ratio assessed by age group among the residents of a rural town in Japan

Excess salt intake causes hypertension and cardiovascular disease (CVD). We examined estimated 24-h urinary sodium (Na) excretion and sodium-to-potassium (Na/K) ratio and analyzed the association between estimated 24-h urinary salt excretion (urinary salt excretion) and dietary habits by age group to develop effective public health programs to promote salt reduction. A total of 4,051 subjects aged 30–74 years old received information during periodic health checkups. In the analysis, 1,202 subjects without hypertension whose urine samples and dietary habits were confirmed (29.7%; 483 men and 719 women) were included. The median urinary salt excretion was 9.1 g/day in men and 8.6 g/day in women. Daily intake of soups in men aged <50 years old and daily intake of beans, soups, or pickles in women aged ≥70 years old were associated with high values of urinary salt excretion (p = .03, p < .01, p = .01, and p = .02, respectively). The median urinary Na/K ratio (mEq/mEq) was 4.4 in both men and women. Daily intake of vegetables in men aged <50 years old and more than 3 days/week intake of fruit in women aged 50–59 and 60–69 years old were associated with lower values of urinary Na/K ratio (p = .03, p < .01, and p < .01, respectively). These findings revealed that dietary salt reduction should be promoted according to age group with regard to differences in dietary habits associated with high values of estimated 24-h urinary Na excretion and urinary Na/K ratio

Estimation of salt intake and sodium-to-potassium ratios assessed by urinary excretion among Japanese elementary school children

Dietary salt intake is largely responsible for the increase in blood pressure with age. It is important to start effective prevention approaches during childhood. In this study, we estimated salt intake and sodium-to-potassium (Na/K) ratios assessed by urinary excretion among elementary school children in Kyoto, Japan. A total of 331 subjects aged 9–11 years participated in school checkups in April 2015. Urinary concentrations of sodium, potassium, and creatinine were measured in first morning urine samples. The subjects’ dietary habits were confirmed by questionnaires completed by their parents. The median estimated urinary sodium excretion was 129.0 mmol/day (5.7g/day of salt). In 30.2% of the subjects, their estimated salt intake exceeded their age-specific dietary goal for salt intake recommended by the Dietary Reference Intakes for Japanese 2015. Multivariate linear regression model analysis after adjustment for age revealed a significant positive correlation between seaweeds or fish paste products consumption and the estimated salt intake (p = 0.02 and 0.02, respectively). The median urinary Na/K ratio (mEq/mEq) was 4.5. Multivariate linear regression model analysis revealed a significant negative correlation between fruit consumption and urinary Na/K ratio (p = 0.04). These results suggest that the high sodium intake and the high Na/K ratios occur among Japanese elementary school children, and that the urinary Na/K ratio in children may be reduced by the daily consumption of fruit

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

Abstract 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 (2.5 and higher, n = 16) women. BMI averaged < 21 kg/m2 and waist < 72 cm and did not differ between two groups. The percentage of macrosomia and serum absolute and fat-mass corrected leptin concentrations were higher in insulin resistant women although there was no difference in birth weight, fat mass index, trunk/leg fat ratio and serum adiponectin. In addition, resting pulse rate, serum concentrations of free fatty acids, triglycerides and remnant-like particle cholesterol were higher in insulin resistant women although HDL cholesterol and blood pressure did not differ. In multivariate logistic regression analyses, serum leptin (odds ratio:1.68, 95% confidential interval:1.08–2.63, p = 0.02) was associated with normal weight insulin resistance independently of macrosomia, free fatty acids, triglycerides, remnant-like particle cholesterol and resting pulse rate. In conclusion, normal weight IR phenotype may be associated with increased plasma leptin concentrations and leptin to fat mass ratio in young Japanese women, suggesting higher leptin production by body fat unit

Trends in Prevalence, Treatment, and Control of Hypertension According to 40-Year-Old Life Expectancy at Prefectures in Japan from the National Health and Nutrition Surveys

The prevalence of hypertension has been decreasing in Japan due to improved medical treatment and a decrease in dietary salt intake. However, disparities in the prevalence, treatment, and control of hypertension are expected to occur in different regions. This study aimed to investigate the trends in the prevalence, treatment, and control of hypertension at the prefectural level of life expectancy among Japanese population. We used data from the National Health and Nutrition Survey and analysed the individual survey information of individuals aged 40&ndash;69 years by dividing it into six terms, i.e., 1995&ndash;1997, 1999&ndash;2001, 2003&ndash;2005, 2007&ndash;2009, 2012, and 2016. Prefectures were classified into four groups according to their 40-year-old life expectancy in 2000. Outcome values were standardised to the population by 10-year age groups in 2010, and they were tested by two-way analysis of variance according to six terms and life expectancies. The prevalence of hypertension tended to decrease, especially among women, whereas the treatment and control tended to improve from the first to the sixth period in both men and women. The prevalence and treatment of hypertension in men with longer life expectancy tended to be lower than that in other groups, and there was no obvious difference in the control. In women, there were no obvious differences in the prevalence, treatment, or control. Reducing the prevalence of hypertension by improving lifestyle factors, such as high salt intake in each prefecture with a relatively short life expectancy, may be important to resolve the disparity in life expectancy among prefectures
