Abstract
Hepatocyte growth factor (HGF) is an adipocytokine elevated in obese subjects. We have previously reported that serum HGF levels were significantly associated with insulin resistance or components of the metabolic syndrome. However, it has been unknown how physical activity (PA) affects HGF levels after a long-term follow-up. Our aim was to clarify the association between PA changes and HGF levels as well as cerebro-cardiovascular disease (CVD) development, during a 10 year follow-up period in a Japanese general population. Of 1320 subjects who received a health check-up examination in Tanushimaru town in 1999, 903 subjects (341 males and 562 females), who received the examination both in 1999 and 2009 were enrolled. We evaluated their PA levels by Baecke questionnaire in 1999 and by a simple questionnaire in 2009. We measured the HGF levels by ELISA method in 1999 and 2009. We divided the subjects into four PA groups, stable low PA, increased PA, decreased PA, and stable high PA. Using these questionnaires, we compared their PA and HGF levels after an interval of 10 years. A significant inverse association was found between PA changes and HGF levels at 10 years, after adjustment for age and sex. The HGF levels of the increased PA group were significantly lower than stable low PA (p = 0.038), and the increased PA group showed reduced CVD development compared to the stable low PA group after adjustment for age and sex (p = 0.012). Our data demonstrated that improvement of PA levels was associated with reduced HGF levels and CVD development.

Abstract
Introduction:
Chronic kidney disease (CKD) is a growing public health problem with aging society and a progression to end-stage renal disease is associated with a higher risk of death. Previous studies have suggested that healthy dietary patterns like vegetable-based diet may reduce risk of incident CKD in general populations. However, there is less evidence on whether dietary patterns have impact on early stage of renal dysfunction (RD). Therefore, we investigated the longitudinal association between dietary patterns and early stage of RD in a general population.
Methods:
We recruited 1943 men and women aged 40 to 95 years in the prospective Tanushimaru cohort study in Japan in 2009. Their dietary intake was assessed using a brief self-administered diet history questionnaire (BDHQ). Principal component analysis (PCA) identified the main dietary patterns. In 984 participants re-examined in 2018, estimated glomerular filtration rate (eGFR) was calculated by CKD-EPI method in 2009 and 2018. RD and early RD were defined as eGFR < 60 and < 90 mL/min/1.73m
2
, respectively . Multivariable linear and logistic regression analyses were performed to examine the association of the main dietary patterns in 2009 with RD and early RD in 2018. Covariates included cardiovascular risk factors and eGFR at baseline.
Results:
Mean levels of eGFR in 2009 and 2018 were 94.0 and 84.3 mL/min/1.73m
2
. The prevalence of RD and early RD in 2018 were 8.8% (n=87) and 58.5% (n=576), respectively. The PCA revealed three major dietary patterns: vegetable pattern (vegetables, mushrooms and seaweeds); rice pattern (rice, bread and miso soup); and alcohol pattern (alcoholic beverages, cakes and snacks). The higher vegetable pattern score was significantly associated with higher eGFR in 2018 (p=0.006) and modestly associated with lower risk of early RD (p=0.06), but not RD (p=0.1) in the fully-adjusted models.
Conclusions:
The vegetable pattern was significantly associated with higher eGFR and may prevent an early stage of RD in a 9-year follow-up.

Abstract
Objective Data on the role of sleep in the risk of insulin resistance (IR) are lacking. We therefore examined the association between sleep duration and IR in a general Japanese population. Methods Data of 1,344 individuals 34 to 89 years old from the Tanushimaru Study were analysed. IR was calculated using the fasting plasma glucose level×fasting insulin level/405, i.e. the homeostasis model assessment of IR (HOMA-IR). IR was defined as a HOMA-IR ≥1.73 based on the diagnostic criteria used in Japan. Information regarding sleep duration was collected via questionnaire. Results The frequencies of IR and metabolic syndrome (MetS) were 36.7% and 26.9%, respectively. A J-shaped relationship between sleep duration and IR was observed, and the same relationship was also shown between sleep duration and MetS; however, the relationship with MetS disappeared after adjusting for age, sex, and other confounding factors. Conclusion A J-shaped relationship was observed between sleep duration and the risks of IR in a general Japanese population.

Abstract
Severe hypertension in pregnancy is a hypertensive crisis that requires urgent and intensive care due to its high maternal and fetal mortality. However, there is still a conflict of opinion on the recommendations of antihypertensive therapy. This study aimed to identify the optimal blood pressure (BP) levels to prevent severe hypertension in pregnant women with nonsevere hypertension. Ovid MEDLINE and the Cochrane Library were searched, and only randomized controlled trials (RCTs) were included if they compared the effects of antihypertensive drugs and placebo/no treatment or more intensive and less intensive BP-lowering treatments in nonsevere hypertensive pregnant patients. A random effects model meta-analysis was performed to estimate the pooled risk ratio (RR) for the outcomes. Forty RCTs with 6355 patients were included in the study. BP-lowering treatment significantly prevented severe hypertension (RR, 0.46; 95% CI, 0.37-0.56), preeclampsia (RR, 0.82; 95% CI, 0.69-0.98), severe preeclampsia (RR, 0.38; 95% CI, 0.17-0.84), placental abruption (RR, 0.52; 95% CI, 0.32-0.86), and preterm birth (< 37 weeks; RR, 0.81; 95% CI, 0.71-0.93), while the risk of small for gestational age infants was increased (RR, 1.25; 95% CI, 1.02-1.54). An achieved systolic blood pressure (SBP) of < 130 mmHg reduced the risk of severe hypertension to nearly one-third compared with an SBP of ≥ 140 mmHg, with a significant interaction of the BP levels achieved with BP-lowering therapy. There was no significant interaction between the subtypes of hypertensive disorders of pregnancy and BP-lowering treatment, except for placental abruption. BP-lowering treatment aimed at an SBP < 130 mmHg and accompanied by the careful monitoring of fetal growth might be recommended to prevent severe hypertension.

Abstract
Although we have found that increased serum levels of glyceraldehyde-derived advanced glycation end products (AGEs) are associated with numerous aging-related disorders, it remains unclear which structurally distinct AGEs could be a reliable biomarker of the healthy life-threatening disorders. Since pentosidine is produced by glyceraldehyde, we measured here urinary pentosidine levels with a newly developed enzyme-linked immunosorbent assay (ELISA) kit, which requires no pretreatment with acid hydrolysis and heat, and examined their correlations with geriatric syndrome, such as musculoskeletal disease, frailty, and cognitive impairment, in a general population. Multiple regression analysis revealed that female, age, history of fracture after fall, and taking medication for diabetes were independent correlates of log urine pentosidine-to-creatinine ratio (R2 = 0.190). When gender-adjusted log urine pentosidine-to-creatinine ratio stratified by smile frequency grade was compared using analysis of covariance, urine pentosidine-to-creatinine ratio was significantly decreased according to the increase in smile frequency. Our present findings suggest that measurement of urine pentosidine-to-creatinine ratio by a newly developed ELISA kit may be useful for identifying high-risk patients for fall-related fractures.

Abstract
Background Remnant-like particle cholesterol (RLP-C) is highly atherogenic, which is associated with atherosclerosis. However, RLP-C has not been routinely measured in the clinical practice. We estimated RLP-C levels using conventional lipid profiles and examined the association between estimated RLP-C and related factors including nutrient intake. Methods This study was performed in Uku town, Nagasaki prefecture, Japan in 2019. A total of 225 subjects were enrolled and directly measured RLP-C levels. Estimated RLP-C levels were defined as the following formula [total cholesterol − (LDL-cholesterol) − (HDL-cholesterol)]. Multivariate analyses were used to assess the relationship between estimated RLP-C and atherogenic factors. We calculated cut-off values on dichotomized RLP-C (< 7.5 mg/dL vs. ≥ 7.5 mg/dL) by receiver operating characteristic (ROC) curve. Results The mean values of directly measured RLP-C levels and estimated RLP-C were 4.0 mg/dL and 16.4 mg/dL, respectively. In the multiple stepwise linear regression analysis, directly measured and estimated RLP-C levels were independently and commonly associated with apolipoprotein E, triglycerides, and vegetable fat intake (inversely). Using ROC curves, we found the cut-off value of estimated RLP-C was 22.0 mg/dL. Conclusion We demonstrated that the estimated RLP-C levels using conventional lipid profiles may substitute for directly measured RLP-C and these levels were independently and inversely associated with vegetable fat intake in the community-dwelling Japanese population.

Abstract
BACKGROUND Elevated blood pressure is a major risk factor for cardiovascular (CV) disease. But the effects of sodium intake or excretion on CV mortality are uncertain. The present study aimed to investigate the association between 24 h urinary sodium excretion, as a marker of dietary salt intake, and CV or cancer mortality in a healthy Japanese population using 24 hurine collection. METHODS The baseline study was conducted in 1980. A total of 1291 participants aged 21 to 85 years, underwent health check-ups, which included blood chemistry measurements and the collection of 24 h urine samples. Enrolled 1291 participants were followed up for 27.5 years, in whom the final follow-up rate was 95.8%. Cox proportional hazards regression models were used to assess the association between 24 h urinary sodium excretion and CV or cancer mortality. RESULTS The mean 24 h urinary sodium excretion was 5.80 ± 2.28 g/day. There were 631 deaths: 153 (27%) from cancer, 142 (26%) from CV disease. In the Cox proportional hazard regression model after adjustment for confounding factors, systolic and diastolic blood pressures, and uric acid were positively associated with CV mortality, and the 24 h urinary sodium and potassium excretions were inversely associated with CV mortality (p < 0.05). On the other hand, there were no association between 24 h urinary sodium excretions and cancer mortality. We divided the urinary sodium excretions levels into quartiles. After adjustment for confounding factors, the hazard ratio of CV mortality in the highest quartile of 24 h urinary sodium excretion versus the lowest was 0.46 (p < 0.05). The cumulative survival rate for CV death was significantly decreased in the lowest quartile compared with the other higher groups. CONCLUSIONS We found that impacts of 24 h sodium excretion on CV and cancer mortalities were much different in the general population.

Abstract
Background There is little data on the association between the lower nutrition represented by serum albumin levels and related factors in a general population. The present study aimed to determine whether the albumin level positioned as some kind of biomarker with frailty measures, trace elements, and an inflammation marker. Methods In 2018, we performed an epidemiological survey in 1368 subjects who resided in Tanushimaru, Japan, in which we examined the blood chemistry including albumin, trace elements, hormone levels, and carotid ultrasonography. Albumin levels were categorized into 4 groups (G1 [3.2–3.9 mg/dL], G2 [4.0–4.3 mg/dL], G3 [4.4–4.6 mg/dL], and G4 [4.7–5.3 mg/dL]). The participants underwent measurements of handgrip strength and were tested by asking to walk 5 m. Their cognitive functions were evaluated by the mini-mental state examination (MMSE). Results Multiple stepwise regression analysis demonstrated that albumin levels were significantly and independently associated with age (inversely), systolic blood pressures, estimated glomerular filtration rate (eGFR), MMSE score, frailty measures (handgrip strength), an inflammation marker (high-sensitivity C-reactive protein), hormones (growth hormone (inversely) and insulin-like growth factor-1), and trace elements (calcium, magnesium, iron, and zinc), with a linear trend. Conclusions Lower albumin levels, even in the normal range, were found to be related factors of frailty measures, trace elements, and an inflammation marker in a general population.

Abstract
BACKGROUND Both homocysteine (Hcy) and asymmetric dimethylarginine (ADMA) induce endothelial dysfunction. However, the impact of both elevations on all-cause death is not known. We investigated the association between elevations of Hcy or ADMA and all-cause death in a general population. METHODS A total of 517 subjects (224 men, 293 women; mean age, 62.8 years) were recruited from a population-based survey in 1999 in Tanushimaru, and we measured fasting plasma Hcy and ADMA levels. We followed them up for over 20 years and examined the effect on mortality using Cox proportional hazard regression model. RESULTS The mean follow-up years were 17.7 (1.8-20.8). In this period, 182 subjects have died (35.2%). The correlation between Hcy and ADMA was high (r=0.194; p<0.001). With Cox regression analysis after adjustments for age and sex, elevated log transformed Hcy levels were significantly associated with all-cause death (p=0.028). When Hcy and ADMA levels were divided into quintiles, the hierarchical model showed the synergistic effect of Hcy and ADMA on all-cause death. CONCLUSIONS This is the first report that we have measured Hcy and ADMA levels simultaneously in this community-dwelling Japanese, and we demonstrated that combined elevations of Hcy and ADMA had big impact on all-cause death in this epidemiological study.

Abstract
Aim: Proprotein convertase subtilisin/kexin type 9 (PCSK9) has been identified as an important regulator of low-density lipoprotein (LDL) receptor processing. Evolocumab and alirocumab are PCSK9 inhibitors; however, little is known about the association between PCSK9 levels and lipid profiles in a general population. Because PCSK9 inhibitors have LDL-C lowering effects, we investigated whether there is a positive correlation between serum PCSK9 levels and LDL-C or lipoprotein(a) [Lp(a)]. Methods: In Uku town, 674 residents (mean age; 69.2 ± 8.3 years) received health check-ups. The participants underwent a physical examination and blood tests, including PCSK9 and Lp(a). Serum PCSK9 and Lp(a) were measured by ELISA and Latex methods, respectively. HOMA-IR was calculated by fasting plasma glucose × insulin levels/405. Results: The mean (range) of PCSK9 and Lp(a) were 211.2 (49–601) ng/mL and 60 (1–107) mg/dL, respectively. Because of a skewed distribution, the log-transformed values were used. With univariate linear regression analysis, PCSK9 levels were associated with Lp(a) (p = 0.028), triglycerides (p < 0.001), and HOMA-IR (p < 0.001), but not with LDL-C (p = 0.138) levels. Multiple stepwise regression analysis revealed that serum PCSK9 levels were independently associated with triglycerides (p < 0.001), Lp(a) (p = 0.033) and HOMA-IR (p = 0.041). Conclusions: PCSK-9 is independently associated with triglycerides, Lp(a) levels, and HOMA-IR, but not LDL-C, in a relatively large general population sample.

Abstract
It is well known that subjects with metabolic syndrome show an elevated resting heart rate. We previously reported that elevated heart rate was significantly related to all-cause mortality, and that coffee consumption was inversely associated with metabolic syndrome. We hypothesized that higher coffee consumption may decrease all-cause mortality by reducing resting heart rate. We performed a longitudinal epidemiological study in Tanushimaru (a cohort of the Seven Countries Study). A total of 1920 residents aged over 40 years received health checkups in 1999. We measured components of metabolic syndrome, and eating and drinking patterns were evaluated by a food frequency questionnaire. We followed up the participants annually for 15 years. During the follow-up period, 343 of the participants died. Of these, 102 subjects died of cancer, 48 of cerebro-cardiovascular diseases, and 44 of infectious diseases. Multivariate analyses revealed that higher coffee consumption was inversely associated with resting heart rate. Kaplan-Meier curves found lower mortality rates in the higher coffee consumption groups. In the lower coffee consumption groups, elevated hazard ratios of all-cause death were observed in the increased heart rate quintiles, whereas heart rate was not associated with all-cause death in the higher coffee consumption groups. These significant associations remained after further adjustment for confounders. This prospective study suggests that higher coffee consumption may have a protective effect against all-cause death due to reducing resting heart rate.

Abstract
AIMS It is well known that a decline in physical activity is associated with an increase of all-cause death including cardiovascular events and cancer. Few studies have examined the association between occupational sitting time and mortality. Therefore, we investigated this issue in a general population. METHODS Physical activity and occupational sitting time were measured using the Baecke physical activity questionnaire in 1999. The questionnaire generated indices in three physical activity categories: work, sport and leisure-time. A total physical activity index was calculated by adding these three indices. The Baecke physical activity questionnaire was able to evaluate occupational sitting time. Hazard ratios and 95% confidence intervals (CIs) were calculated using Cox's proportional hazard regression models. RESULTS We enrolled a total of 1680 participants, who were followed up for 15.9 ± 3.8 years. The final follow-up rate was 93%. During the follow-up period, 397 subjects died. A significant inverse association (p < 0.0001) was found between physical activity and mortality after adjustment for age and sex. Compared with lower levels of physical activity, the adjusted hazard ratio for mortality at higher levels of physical activity was 0.85 (95% CI: 0.78-0.92). Longer occupational sitting time was also significantly associated with higher mortality (p < 0.01). The adjusted hazard ratio for mortality at longer occupational sitting time was 1.16 (95% CI: 1.05-1.27). These findings were observed in males, but not in females. CONCLUSIONS Our data demonstrated that higher levels of physical activity are associated with a reduced risk of cancer and cardiovascular death. Further, longer occupational sitting time is associated with increased mortality.

Abstract
Background Few studies have examined the relationship between accurate monitoring of sodium or potassium consumption and mortality. We aimed to investigate the association between 24‐hour urinary sodium or potassium excretion and ≈30‐year mortality in a Japanese population using 24‐hour urine collection. Methods and Results We enrolled a total of 1291 participants, aged 21 to 85 years, who underwent health checkups, including a blood test and 24‐hour urine collection. They were followed up for 27.5±9.9 years by December 31, 2015, and the final follow‐up rate was 95.8%. Cox proportional hazards regression analysis was used to assess the association between 24‐hour urinary sodium or potassium excretion and all‐cause mortality. At baseline, the mean 24‐hour urinary sodium and potassium excretions were 5.80±2.28 g/d and 1.85±0.82 g/d, respectively. There were 631 deaths during the follow‐up. The cumulative survival rate was significantly decreased in the lowest quartile compared with the other higher groups. In the Cox proportional hazard model after adjustment for age and sex, 24‐hour urinary potassium excretion, but not sodium excretion, was inversely associated with all‐cause mortality. We divided the 24‐hour urinary potassium excretion levels into quartiles. After adjustment for confounding factors, the hazard ratio of all‐cause mortality in the highest quartile of 24‐hour urinary potassium excretion versus the lowest was 0.62 (95% confidence interval, 0.48–0.79; P<0.001). Conclusions The 24‐hour urinary potassium excretion, but not sodium excretion, was significantly associated with all‐cause mortality in the general population.

Abstract
BACKGROUND Transforming growth factor β1 (TGF-β1) is a multifunctional cytokine. There is growing evidence that TGF-β1 is involved in the pathogenesis of hypertension and the development of target organ damage in hypertensives. Although several studies have shown that TGF-β1 induced vascular hypertrophy and remodelling in various vascular diseases, there are no longitudinal data on hypertension in the epidemiological studies. The present study tested the hypothesis whether elevated TGF-β1 levels can predict the development of hypertension. METHODS In 2002-2004, 528 subjects received health examinations in Uku town, southwestern Japan. We examined blood pressure (BP), body mass index, and blood test. Data on fasting plasma TGF-β1 were obtained from 528 individuals. Of these, 149 normotensives (BP <140/90 mm Hg without antihypertensive medications) at baseline were followed-up for 14 years. RESULTS The receiver-operating characteristic curve was used and the calculated cutoff value was 8.9 ng/ml. Of 149 normotensives at baseline, 59 subjects developed hypertension. Plasma TGF-β1 levels were significantly associated with the development of hypertension after adjustment for confounding factors. To further examine the association between them, we performed logistic regression analysis. We divided the baseline plasma TGF-β1 levels into 2 groups using a cutoff value. The significant high odds ratio [3.582 (95% confidence interval, 1.025-12.525)] for the development of hypertension was found in the highest group of TGF-β1 level vs. the lowest group after adjustment for confounders. CONCLUSIONS This is the first report demonstrating the causal relationship between them. Elevated plasma TGF-β1 levels predicted the development of hypertension in normotensives in a population of community-dwelling Japanese.

Abstract
Accumulation of visceral fat leads to metabolic syndrome and increases risks of cerebro-cardiovascular diseases, which should be recognized and improved at the early stage in general population. Accurate measurement of visceral fat area (VFA) is commonly performed by the abdominal cross-sectional image measured by computed tomography scan, which is, however, limited due to the radiation exposure. The bioelectrical impedance analysis (OMRON, HDS-2000 DUALSCANR) has been recently developed to measure VFA, which is more easily accessible modality. In the present study, we investigated the clinical usefulness of DUALSCANR in 226 subjects who received health examination, including blood chemistries, electrocardiography, cardio, and carotid ultrasonography. VFA was measured within only just 5 min. Average of VFA was 83.5 ± 36.3 cm2 in men, and 64.8 ± 28.0 cm2 in women, which was correlated to weight (r = 0.7404, p < 0.0001), body mass index (BMI) (r = 0.7320, p < 0.0001), and waist circumstance (r = 0.7393, p < 0.0001). In multivariate analyses, VFA was significantly associated with weight (p < 0.0001), BMI (p < 0.0001), and waist circumstance (p < 0.0001). Compared to the group of smaller waist and normal BMI, VFA was significantly increased (p < 0.0001) in the group of larger waist and obese subjects. In conclusion, these results indicated that DUALSCANR is useful to measure VFA easily in general population, even in a large number of subjects.

Abstract
BACKGROUND An understanding of the trends in regard to coronary risk factors and electrocardiogram (ECG) findings has an important role in public health. We investigated the trends in coronary risk factors and main ECG findings in 1977, 1989, 1999, and 2009 in the Japanese cohort of the Seven Countries Study, in Tanushimaru, a typical farming town on Kyushu Island. METHODS AND RESULTS A total of 1397 subjects (231 in 1977, 332 in 1989, 389 in 1999, and 445 in 2009) were enrolled in this study, and all of them were males aged over 65 years. In coronary risk factors, total cholesterol levels, diastolic blood pressure, body mass index, and uric acid significantly increased during these 3 decades. The prevalence of smokers markedly decreased from 56.7% in 1977 to 16.8% in 2009. ECG changes during 3 decades were wider QRS interval, increased prevalence of major abnormality, reduced heart rate, shortened PR interval and corrected QT, and decreased prevalence of left ventricular hypertrophy. Age, smoking habits, major and minor abnormalities in ECG were associated with mortality in 1977-1987. Age, total cholesterol levels (inversely) and corrected QT were associated with mortality in 1989-1999. Age, smoking habits, heart rate, and systolic blood pressure were associated with mortality in 1999-2009. CONCLUSIONS Predictors of mortality have changed with the times. Coronary risk factors such as smoking, increased heart rate, and elevated blood pressure have been recently associated with mortalities in elderly male Japanese general population.

Abstract
We investigated the relationship between augmentation index (AI) and smoking habits in community-dwelling Japanese.This cross-sectional study enrolled 1926 subjects (769 males and 1157 females) aged 40 to 95 years who underwent a health check-up in a Japanese cohort of the Seven Countries Study, in Tanushimaru, a typical farming town in Kyushu Island in 2009. The subjects' medical history, alcohol intake, smoking habit, and current medications for hypertension, dyslipidemia, and diabetes were ascertained by questionnaire. Radial arterial pressure wave analysis was used to obtain AI. We analyzed the data stratified by gender.Age-adjusted means of AI in males showed a clear dose-response relationship in 4 categories of smoking habits (P = 0.010). There was no significant relationship between AI and smoking habits in females (P = 0.127). The significant dose-response relationship (P = 0.036) in males between AI and 4 categories of smoking habits still remained even after adjustment for age, body mass index, systolic blood pressure, estimated glomerular filtration rate, glucose, hypertensive medication, and alcohol intake.The present study demonstrated that AI values were significantly associated with smoking habits in a dose-dependent manner in Japanese males.

Abstract
Objective There is little long-term data on the association between the serum albumin levels and mortality in community-based populations. We aimed to determine whether the serum albumin level is an independent risk factor for all-cause and cause-specific death in a community-based cohort study in Japan. Methods In 1999, we performed a periodic epidemiological survey over a 15-year period in a population of 1,905 healthy subjects (783 males, 1,122 females) who were older than 40 years of age and who resided in Tanushimaru, a rural community, in Japan. Over the course of the study, we periodically examined the blood chemistry of the study subjects, including their serum albumin levels. Their baseline serum albumin levels were categorized into quartiles. Results The baseline albumin levels were significantly associated with age (inversely), body mass index (BMI), diastolic blood pressure, lipid profiles [high density lipoprotein-cholesterol (HDL-c), low-density lipoprotein-cholesterol (LDL-c) and triglycerides] and estimated glomerular filtration rate (eGFR). After adjusting for confounders, a Cox proportional hazards regression analysis demonstrated that a low serum albumin level was an independent predictor of all-cause death [hazard ratio (HR): 0.39, 95% confidence interval (CI): 0.24-0.65], cancer death (HR: 0.43, 95% CI: 0.18-0.99), death from infection (HR: 0.21, 95% CI: 0.06-0.73) and cerebro-cardiovascular death (HR: 0.19, 95% CI: 0.06-0.63). The HRs for all-cause and cerebro-cardiovascular death in the highest quartile vs. the lowest quartile of albumin after adjusting for confounders were 0.59 (95%CI:0.39-0.88) and 0.15 (95%CI: 0.03-0.66), respectively. Conclusion The serum albumin level was thus found to be a predictor of all-cause and cerebro-cardiovascular death in a general population.

Abstract
BACKGROUND Heart rate is a strong predictor of mortality and development of obesity and diabetes. The renin-angiotensin-aldosterone system plays an important role in blood pressure control and volume homeostasis. Although many studies have indicated the association between aldosterone and hypertension or insulin resistance, epidemiological evidence of the association of heart rate with plasma renin activity (PRA) remains scant. Therefore, we investigated whether heart rate is associated with PRA. METHODS A total of 1,943 subjects were enrolled, who underwent a health examination in Tanushimaru in 2009. Plasma renin and aldosterone concentrations were measured by radioimmunoassay. PRA and the homeostasis model assessment (HOMA) were used by natural-log transformed. Resting heart rate was measured using electrocardiography. RESULTS We divided the subjects into four groups by heart rate (<60/min, 60-69/min, 70-79/min, ≥80/ min), and analyzed an association between PRA and heart rate by analysis of covariance after adjustments for age and sex. The adjusted mean PRA and HOMA index showed a significant trend (P < 0.01) as higher heart rate, although there was no significant trend between aldosterone and heart rate (P = 0.26). In multiple linear regression analysis adjusted for age, sex, systolic blood pressure, HOMA index, and hypertensive medication, PRA was positively and strongly associated with elevated heart rate (P < 0.01). CONCLUSIONS This epidemiological study demonstrated that PRA, but not aldosterone, is significantly and positively associated with higher resting heart rate in a general population.

Abstract
BACKGROUND In patients with cardiovascular diseases, inflammatory and hemostatic biomarkers are significant indicators of prognosis. We investigated whether circulating inflammatory and hemostatic biomarkers were predictive markers for all-cause death and cancer death in a population of community-dwelling Japanese. METHODS We studied 1,920 healthy Japanese adults who underwent health examinations in 1999. Those who reported a history of inflammatory diseases and malignancy on a baseline questionnaire were excluded. Inflammatory and hemostatic biomarkers were measured in the remaining 1,862 participants, who were followed up periodically for 10 years. Multivariate proportional hazards regression analysis was used to estimate all-cause and cancer mortality. RESULTS A total of 258 participants died during follow-up: 87 from cancer, 38 from cerebro-cardiovascular diseases, and 133 from other diseases. Mean C-reactive protein (CRP) levels at baseline were significantly higher in decedents than in survivors. Mean von Willebrand factor (vWF) levels at baseline were significantly higher in decedents than in survivors. The Cox proportional hazards model after adjustments for age and sex showed that CRP (hazard ratio [HR], 1.26; 95% confidence interval [CI], 1.06-1.51) and vWF (HR, 1.01; 95% CI, 1.00-1.01) were independent predictors of all-cause death. CRP (HR, 1.40; 95% CI, 1.06-1.86) and vWF (HR, 1.01; 95% CI, 1.00-1.02) were also independent predictive markers for cancer death. CONCLUSIONS Serum CRP and vWF were predictors of all-cause death and cancer death in the population of community dwelling Japanese.

Abstract
Aims/Introduction Ezetimibe lowers serum lipid levels by inhibiting intestinal absorption of dietary and biliary cholesterol. However, the effect of ezetimibe on insulin resistance remains unclear. The aim of the present study was to examine this issue in patients with metabolic syndrome in local-dwelling Japanese, who were not being treated with lipid-lowering drugs. Materials and Methods In 2009, 1,943 participants received a health examination in the Tanushimaru Study, a Japanese cohort of the Seven Countries Study, of whom 490 participants had metabolic syndrome. Among them, 61 participants (41 men and 20 women) were examined in the present study. They were treated with 10 mg of ezetimibe once a day for 24 weeks, combined with standard diet and exercise therapy. Results Bodyweight (P < 0.001), body mass index (P < 0.001), systolic blood pressure (P = 0.003), diastolic blood pressure (P < 0.001), triglycerides (P = 0.002), non-high-density lipoprotein cholesterol (P = 0.001), low-density lipoprotein cholesterol (P < 0.001) and homeostasis model assessment of insulin resistance (P = 0.011) significantly decreased after the observational period. There were no statistically significant differences in the effects of ezetimibe between men and women. Univariate analysis showed that the reduction of homeostasis model assessment of insulin resistance was not associated with the improvement of other metabolic components. Conclusions Ezetimibe combined with standard diet and exercise therapy improves not only bodyweight and atherogenic lipid profiles, but also insulin resistance, blood pressure and anthropometric factors in metabolic syndrome in local-dwelling Japanese. Interestingly, the improvement of insulin resistance had no correlation with other metabolic components.

Abstract
AIMS Fetuin-A, a protein exclusively secreted from the liver, is associated with insulin resistance and/or metabolic syndrome (MetS). However, few studies have examined this association in Japan. We investigated this issue in a Japanese general population. METHODS We performed an epidemiological survey in a small community in Japan. The participants consisted of 659 subjects (253 males and 406 females). Fetuin-A levels were measured by a sandwich ELISA method and the modified NCEP-ATP III criteria were adopted to diagnose MetS. The homeostasis model assessment index (HOMA-IR) was calculated as a marker of insulin resistance. RESULTS Statistically significant characteristics of the 659 subjects stratified by fetuin-A quartiles were male gender (inversely), age (inversely), insulin, HOMA-IR, uric acid (inversely), alcohol intake (inversely) and the prevalence of MetS. Mean fetuin-A levels were 249.7±45.1μg/ml in males and 262.7±55.8μg/ml in females. In males, the prevalence of MetS was 43.1%, and their mean HOMA-IR level was 1.1. In females, the prevalence of MetS was 17.7%, and their mean HOMA-IR level was 0.9. Multiple stepwise regression analyses showed that fetuin-A levels in males but not females were independently associated with MetS and LDL-c. Multiple logistic regression analysis of fetuin-A (quartile 1 vs. quartile 4) in males showed significant odds ratios of 1.009 (95% C.I.: 1.003-1.015) for MetS and 1.376 (95% C.I.: 1.027-1.844) for 1-SD increment increase in LDL-c. CONCLUSIONS High plasma fetuin-A levels were associated with MetS in community-dwelling Japanese males but not females.

Abstract
The association of serum uric acid (UA) with left ventricular hypertrophy (LVH) remains controversial. We investigated this issue in a general population. Participants consisted of 1,943 subjects (774 males and 1,169 females) aged over 40 years, living in Tanushimaru (a Japanese cohort of the Seven Countries Study). Serum UA and other biochemistry parameters were determined by a standard analytical technique. All individuals underwent anthropometric measurements and 2-dimensional echocardiography. Because serum UA levels are much higher in males than in females, they were analyzed separately. When LV mass index (LVMI) levels were stratified according to tertile as low (≤ 80 cm(2): n = 261), middle (81-103 cm(2): n = 261), and high (≥ 104 cm(2): n = 252) in males, there were significant relationships between LVMI and UA, in addition to age, body mass index, systolic blood pressure, medication for hypertension, triglycerides, and alcohol intake. Multiple stepwise regression analysis revealed LVMI was significantly associated with systolic BP (P < 0.0001), medication for hypertension (P < 0.0001), UA (P = 0.003), BMI (P = 0.019), and alcohol intake (P = 0.038) in males. In females, LVMI was not associated with UA. In a multiple logistic regression analysis, a significantly higher odds ratio of LVH (odds ratio: 1.77, 95%CI: 1.01-3.09, P < 0.05) was observed for males in the highest UA tertile versus the lowest UA tertile after adjustments for confounding factors, but not for females. In this cross-sectional study, there was a clear difference in the relation of UA and LVH between males and females. High serum UA was significantly and independently associated with LVH evaluated by echocardiography in only males of a general population.

Abstract
OBJECTIVE Hepatocyte growth factor (HGF) receptors form a hybrid complex with insulin receptors in the liver of mice, which lead to robust signalling to regulate glucose metabolism. Serum HGF levels are high in subjects with metabolic syndrome and/or obesity. Accordingly, we prospectively investigated the relationship between HGF and the development of insulin resistance (IR) in a general population without IR at baseline. METHODS A total of 1492 subjects received health examinations. After excluding subjects with diabetes and/or IR (n = 402) at baseline, the remaining subjects (n = 1090) were followed-up 10 years later. Complete data sets were available from 716 subjects for prospective analysis. Logistic regression was performed to determine factors associated with the development of IR after 10 years. RESULTS In subjects without diabetes at baseline, serum HGF levels were higher (0·26 ± 0·10 ng/ml, n = 259) in subjects with IR than without it (0·22 ± 0·09 ng/ml, n = 1090). After deleting subjects who developed liver disease during follow-up, 188 were found to have developed IR at 10 years after the original screening. HGF (P < 0·05), age (P < 0·001), homoeostasis model assessment index (P < 0·001), HDL-c (P < 0·05; inversely) and hypertensive medication (P < 0·05) were significantly associated with the development of IR by multivariate stepwise logistic regression analysis. A significant (P < 0·05) relative risk [1·75 (95%CI: 1·01-3·12)] for the development of IR was observed in the highest (≥0·30 ng/ml) vs the lowest categories (<0·15 ng/ml) of HGF after adjustments for confounders. CONCLUSIONS Our 10-year prospective study suggests that elevated serum HGF levels were significantly associated with the development of IR.

Abstract
BACKGROUND Remnant-like lipoprotein particle cholesterol (RLP-C) is a highly atherogenic factor. RLP-C induces endothelial dysfunction and is associated with hyperinsulinemia. This study was designed to determine whether high plasma RLP-C levels predispose to the development of hypertension in subjects with normal blood pressure (BP). METHODS A total of 1,485 subjects aged >40 years in a Japanese Cohort of the Seven Countries Study received health examinations. We examined BP, anthropometric parameters, and blood chemistries, including fasting RLP-C levels. RLP-C levels were measured by an immune-separation method. We excluded from the analysis 676 subjects who had hypertension (BP ≥ 140/90mm Hg), or were on antihypertensive medication, and/or were on antihyperlipidemic medication at baseline. Ten years later, 681 subjects were re-examined. RESULTS Of 681 normotensive subjects at baseline, 303 subjects had developed hypertension 10 years later. Baseline RLP-C level was significantly higher (P < 0.01) in the subjects who developed hypertension than in those who remained normotensive (3.7±1.9 vs. 3.3±1.6mg/dl). Multivariable logistic regression analysis demonstrated that baseline RLP-C was a significant factor for incident hypertension after adjustments for homeostasis model assessment index and other hypertension-related factors (odds ratio = 1.05, 95% CI = 1.00-1.10; P = 0.04). CONCLUSIONS A high level of plasma RLP-C in normotensive subjects may predispose to the development of hypertension in a population of community-dwelling Japanese.

Abstract
BACKGROUND Large cohort studies have revealed that subjects with atherosclerotic risk factors have high mortality. However, there has been no method to predict individual mortality based on these risk factors. Accordingly, we developed a computer model predicting the 10-year mortality of an individual with atherosclerotic risk factors. METHODS We enrolled two different cohorts in Japan. One was from Tanushimaru-town and the other was from Uku-town. Residents over the age of 40 underwent baseline examinations and were followed-up for ten years. 1851 Subjects in Tanushimaru-town were randomly divided into 1486 training samples and 365 test samples. We applied supervised statistical pattern recognition (SSPR) techniques to develop, using the training samples, a computer model to predict the 10-year mortality of an individual based on 6 conventional risk factors. The test samples were then used to evaluate the predictive accuracy. RESULTS There were 49 deaths and 316 survivors in the test samples in Tanushimaru-town. The correctly simulated number of deaths and survival was 36 and 250, respectively. The predictive accuracy of death was 73.5% (36/49) and that of survival was 79.1% (250/316) with c-statistics of 0.827. In order to verify our model, we predicted death and survival for the other test samples (Uku-town, n = 170). The predictive accuracy of death was 72.9% (35/48) and that of survival was 76.2% (93/122) with c-statistics of 0.848. CONCLUSIONS This is the first computer model to use SSPR methods to estimate individual 10-year mortality based on conventional risk factors with high accuracy.

Abstract
BACKGROUND Hepatitis C virus (HCV) affects glucose and lipid metabolism in vitro; however, it is unclear whether HCV infection is associated with insulin resistance and atherosclerosis at the population level. We aimed to investigate this association in a Japanese cohort of the Seven Countries Study, and our investigation was conducted in Tanushimaru, an HCV hyperendemic area. METHODS A total of 1908 inhabitants of Tanushimaru were classified into 3 groups according to HCV infection status: those who were uninfected (n = 1780), those with transient infection (n = 88), and those with chronic infection (n = 40). Insulin resistance and atherosclerosis were evaluated by homeostasis model assessment for insulin resistance (HOMA-IR) and carotid intima-media thickness (IMT), respectively. Intergroup differences in variables were evaluated by age- and sex-matched multivariate regression analysis. RESULTS Significant intergroup differences were seen in fasting glucose and insulin levels. The HOMA-IR value was significantly higher in the group with chronic infection than the values in the uninfected and transiently infected groups (3.0 ± 0.39 vs. 1.3 ± 0.03 vs. 1.5 ± 0.14; P < 0.001). In contrast, low-density lipoprotein (LDL)-cholesterol and triglyceride levels were significantly lower in the group with chronic infection than the levels in the other groups. IMT was reduced in the group with chronic infection, with a significant intergroup difference (0.67 ± 0.02 vs. 0.71 ± 0.003 vs. 0.72 ± 0.01 mm; P = 0.003). CONCLUSIONS This population-based study in an HCV hyperendemic area revealed that chronic HCV infection was associated with severe insulin resistance and with mild atherosclerosis, suggesting a unique characteristic of HCV-related metabolic abnormality.

Abstract
BACKGROUND Endothelin-1 (ET-1) is a potent vasoconstrictor and an elevated plasma level is a prognostic marker in patients with cardiovascular diseases and/or malignancies. We hypothesized that an elevated plasma level might be a prognostic marker even in subjects without apparent cardiovascular disease or malignancy at baseline. METHODS AND RESULTS We measured plasma ET-1 levels in 1,440 healthy subjects over 40 years of age (580 men, 860 women) who were periodically followed for 10 years. The follow-up rate was 96.8%. Baseline plasma ET-1 levels were categorized into quartiles. Baseline plasma ET-1 levels were significantly associated with age, blood pressure, high-density lipoprotein-cholesterol, renal function, uric acid and all-cause death, but not with cardiovascular or cancer death. Kaplan-Meier curves demonstrated that all-cause mortality was significantly higher in the highest quartile of ET-1 than in the lowest quartile. Cox proportional hazards regression analysis demonstrated that ET-1 was an independent predictor of all-cause death [hazard ratio: 1.11, 95% confidence interval (CI) 1.01-1.23 per 1 pg/ml difference]. The hazard ratio of all-cause death in the highest quartile of plasma ET-1 (≥5.9 pg/ml) vs. the lowest quartile after adjusting for confounding factors was 1.54 (95% CI 1.09-2.20). CONCLUSIONS The plasma ET-1 level may be a predictor of all-cause death in a healthy population.

Abstract
Background In patients with cancer, hepatocyte growth factor (HGF) is elevated and is a predictor of prognosis. We investigated whether serum HGF was a predictive marker for cancer death in a population of community-dwelling Japanese. Methods We studied 1492 apparently healthy Japanese adults who underwent health examinations in 1999. Those who reported a history of liver disease or malignancy on a baseline questionnaire were excluded, and plasma HGF was measured in the remaining 1470 participants, who were followed periodically for 10 years. Multivariate proportional hazards regression was used to estimate cancer mortality. Results A total of 169 participants died during follow-up (61 from cancer, 32 from cerebrocardiovascular disease, and 76 from other diseases). Mean HGF at baseline was significantly higher among decedents than among survivors (0.26 ± 0.11 vs 0.23 ± 0.09 ng/ml, respectively; P < 0.01). The Cox proportional hazards model showed that age, systolic blood pressure, HGF (hazard ratio, 1.27; 95% CI, 1.06–1.52; P = 0.009), albumin level, smoking status, and creatinine were independent predictors of all-cause death. Age, HGF (hazard ratio, 1.31; 95% CI, 1.04–1.65; P = 0.02), and total cholesterol were independent predictive markers for cancer death. Conclusions Serum HGF was a predictor of cancer death in an apparently healthy population of community-dwelling Japanese.

Abstract
BACKGROUND Angiopoietin-like protein 4 (Angptl4) is thought to cause an increase in serum triglyceride levels. In the present study, we elucidated Angptl4 expression in the mouse models of type 1 and type 2 diabetes mellitus, and investigated the possible mechanisms involved. METHODS Type 1 diabetes was induced in C57BL/6 J mice by treating them with streptozotocin (STZ). Type 2 diabetes was induced by feeding the mice a high-fat diet (HFD) for 18 weeks. RESULTS The levels of Angptl4 mRNA expression in liver, white adipose tissue (WAT), and brown adipose tissue (BAT) were found to increase in the STZ diabetic mice relative to control mice. This effect was attenuated by insulin administration. In the HFD diabetic mice, the Angptl4 mRNA expression levels were increased in liver, WAT, and BAT. Treatment with metformin for 4 weeks attenuated the increased levels of Angptl4 mRNA. Fatty acids (FAs) such as palmitate and linoleate induced Angptl4 mRNA expression in H4IIE hepatoma cells and 3T3-L1 adipocytes. Treatment with insulin but not metformin attenuated FA-induced Angptl4 mRNA expression in H4IIE. Both insulin and metformin did not influence the effect of FAs in 3T3-L1 cells.

Abstract
Aldosterone plays a role in hypertension, and hypertension is prevalent in patients with insulin resistance. Cross-sectional studies have reported that plasma aldosterone levels are higher in patients with insulin resistance. However, it is not known whether plasma aldosterone levels predict the development of insulin resistance. Subjects of the present study were 1235 local residents (490 men and 745 women) who participated in health screenings in Japan in 1999. Plasma aldosterone levels were measured by radioimmunoassay. We investigated the cross-sectional relationship between plasma aldosterone levels and insulin resistance (homeostasis model assessment index ≥1.73 according to the diagnostic criteria used in Japan) in 1088 nondiabetic participants. At the 10-year follow-up, 141 subjects had died, and 260 subjects refused re-examination. We performed a prospective analysis of 564 subjects to predict incident insulin resistance. We found a significant (P<0.001) cross-sectional relationship between plasma aldosterone and homeostasis model assessment index at baseline. In the prospective analysis, a significantly higher (P<0.05) relative risk (1.71 [95% CI: 1.03-2.84]) was observed in the highest tertile versus lowest tertile of plasma aldosterone for the development of insulin resistance, after adjustment for confounding factors. This 10-year prospective study demonstrated that plasma aldosterone levels predicted the development of insulin resistance in a general population.

Abstract
OBJECTIVE Ghrelin is a novel gastric peptide identified in 1999 as a 'hunger hormone'. Plasma ghrelin level is decreased in human obesity. Factors associated with ghrelin have been mainly investigated in western countries where the prevalence of obesity is high. The aim of this study is to examine factors associated with plasma ghrelin in a Japanese general population where obesity is not so common. METHODS Fasting ghrelin levels were measured by ELISA in 638 subjects in 2005-2007. We measured body mass index (BMI), waist circumference and blood pressure. Blood was drawn in the morning after a 12-h fast for determinations of ghrelin, lipid, glucose (FPG), insulin, estimated glomerular filtration rate (eGFR) and uric acid levels. Univariate and multiple stepwise regression analyses were performed to find out factors associated with ghrelin. RESULTS In our population, the mean BMI was 23·8 kg/m(2) , indicating a nonobese population. Results of univariate analysis showed that age (P<0·001), BMI (P<0·001), waist (P<0·001), triglycerides (P<0·01), FPG (P<0·01), insulin (P<0·001) and uric acid (P<0·05) were inversely associated with ghrelin. High-density lipoprotein (HDL) cholesterol (P<0·001) and eGFR (P<0·05) were positively associated with ghrelin. Men had lower ghrelin levels than women (P<0·001). Results of the multiple stepwise regression analysis revealed that age (P<0·001; inversely), female gender (P<0·001), insulin (P<0·001; inversely), HDL cholesterol (P=0·005), BMI (P=0·01; inversely) and uric acid (P=0·045; inversely) were significantly and independently associated with ghrelin. CONCLUSIONS The present study demonstrated that age and gender affected plasma ghrelin levels more than BMI. This may well be because of the low prevalence of overweight in our population.

Abstract
BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) plays a role in cardiovascular disease (CVD) and renal injury. Recent clinical studies have suggested that circulating levels of MCP-1 could be a biomarker of atherosclerosis and future cardiovascular events in humans. Because chronic kidney disease (CKD) is one of the risk factors of CVD, it is conceivable that elevated MCP-1 levels may link the increased risk of CVD in CKD patients. However, as far as we know, in addition to well-known traditional risk factors for atherosclerosis, whether renal dysfunction could be independently associated with the elevation of MCP-1 levels in a general population remains unknown. Therefore, we examined here which anthropometric and metabolic variables, including renal function, could be independent correlates of circulating levels of MCP-1 in a general population. HYPOTHESIS We hypothesized that renal function was one of the independent correlates of serum MCP-1 levels. METHODS A total of 860 Japanese residents (318 males and 542 females, mean age 65.4 ± 9.8 years) in a small fishing community underwent a complete history and physical examination with determination of blood chemistries, including serum levels of MCP-1. RESULTS Mean MCP-1 levels were 281.4 pg/mL. Multiple stepwise regression analyses revealed that male sex (P<0.0001), age (P=0.03), estimated glomerular filtration rate (eGFR) (P<0.0001, inversely), and white blood cell count (P=0.037) were independently associated with MCP-1 levels. CONCLUSIONS The present study demonstrated for the first time that other than white blood cell count, eGFR was an independent correlate of serum levels of MCP-1 in a Japanese general population. Elevated MCP-1 levels may partly explain the increased risk of CVD in CKD patients.

Abstract
High mobility group box 1 (HMGB1), a nonhistone chromatin-associated protein, is implicated as a mediator of both infectious and non-infectious inflammatory conditions. Clinical research on this protein in humans just has begun; serum HMGB1 was reported to be elevated in a small number of critically ill patients suffering from sepsis. However, the kinetics, distribution and factors associated with circulating HMGB1 are unknown in a general population. In this study, we examined these issues in a large population of healthy subjects. Fasting blood samples were obtained from 626 subjects (237 males and 389 females). HMGB1 levels showed a skewed distribution with a mean of 1.65 +/- 0.04 ng/ml. Multiple stepwise regression analyses found that white blood cell (WBC) counts (P = .016) and the soluble form of receptor for advanced glycation end products (sRAGE; P < .001, inversely), which is also known to be a receptor for HMGB1, were independently associated with HMGB1 levels. We demonstrated for the first time that circulating HMGB1 levels were inversely associated with sRAGE levels in a general population. Because RAGE is involved in HMGB1 signaling, our present study suggests that sRAGE may capture and eliminate circulating HMGB1 in humans.
