Electrocardiographic Left Atrial Abnormality and B-Type Natriuretic Peptide in a General Japanese Population: NIPPON DATA2010. J Atheroscler Thromb 2021; 28:34-43. [PMID: 32188793 PMCID: PMC7875149 DOI: 10.5551/jat.54171] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 02/04/2020] [Indexed: 12/21/2022] Open
Abstract
AIMS P-wave terminal force in lead V1 (PTFV1) is an electrocardiogram marker of increased left atrial pressure and may be a noninvasive and early detectable marker for future cardiovascular events in the general population compared to serum B-type natriuretic peptide (BNP) concentration. The clinical significance of PTFV1 in the contemporary general population is an area of unmet need. We aimed to demonstrate the correlation between PTFV1 and BNP concentrations in a contemporary representative Japanese population. METHODS Among 2,898 adult men and women from 300 randomly selected districts throughout Japan (NIPPON DATA2010), we analyzed 2,556 participants without cardiovascular disease (stroke, myocardial infarction, and atrial fibrillation). Elevated BNP was defined as a value of ≥ 20 pg/mL based on the definition from the Japanese Circulation Society guidelines. RESULTS In total, 125 (4.9%) participants had PTFV1. Participants with PTFV1 were older with a higher prevalence of hypertension, major electrocardiographic findings, and elevated BNP concentrations (13.5 [6.9, 22.8] versus 7.8 [4.4, 14.5] pg/mL; P<0.001). After adjustment for confounders, PTFV1 was correlated with elevated BNP (odds ratio, 1.66; 95% confidence interval, 1.05-2.62; P=0.030). This correlation was consistent among various subgroups and was particularly evident in those aged <65 years or those without a history of hypertension. CONCLUSIONS In the contemporary general population cohort, PTFV1 was independently related to high BNP concentration. PTFV1 may be an alternative marker to BNP in identifying individuals at a higher risk of future cardiovascular events in the East Asian population.

Abstract
BACKGROUND This study assessed sex-specific time-associated changes in the impact of risk factors on coronary artery disease (CAD) mortality in a general population over long-term follow-up.Methods and Results:A prospective longitudinal cohort study was conducted on representative Japanese populations followed up for 29 years. Data from 8,396 participants (3,745 men, 4,651 women) were analyzed. The sex-specific multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of 4 risk factors (smoking, diabetes, serum total cholesterol [TC], and systolic blood pressure [SBP]) for CAD mortality were calculated at baseline and at 10, 15, 20, 25, and 29 years of follow-up. In men, smoking (HR 3.23; 95% CI 1.16-9.02) and a 1-SD increase in TC (HR 1.82; 95% CI 1.29-2.57) were strongly associated with a higher risk of CAD in the first 10 years, but this association decreased over time. Diabetes (HR 2.30; 95% CI 1.37-3.85) and a 1-SD increase in SBP (HR 1.23; 95% CI 1.00-1.50) were strongly correlated with a higher risk of CAD after 29 years). In women, diabetes was correlated with CAD after 20 years (HR 2.53; 95% CI 1.19-5.36) and this correlation persisted until after 29 years (HR 2.47; 95% CI 1.40-4.35). CONCLUSIONS The duration of follow-up needed for the accurate assessment of risk factors for CAD mortality varies according to risk factor and sex.

Association of Free Sugars Intake with Cardiometabolic Risk Factors among Japanese Adults: The 2016 National Health and Nutrition Survey, Japan. Nutrients 2020; 12:nu12123624. [PMID: 33255814 PMCID: PMC7761430 DOI: 10.3390/nu12123624] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 11/23/2020] [Accepted: 11/24/2020] [Indexed: 11/23/2022] Open
Abstract
The relationship between free sugars intake and cardiometabolic risk factors is unclear in Japanese adults. This cross-sectional study aimed to investigate this association using data from the 2016 National Health and Nutrition Survey, Japan. The percentage of energy intake from free sugars was estimated based on the 1-day weighed dietary record data of Japanese men (n = 4071) and women (n = 5794) aged ≥ 20 years. Associations between free sugars intake and cardiometabolic risk factors, including body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressures, glycated haemoglobin (HbA1c) level and levels of serum total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol, were investigated using linear regression and Dunnett’s test, with the lowest category of quartiles as a reference. After adjustment for potential confounding factors, free sugars intake was inversely associated with blood pressures (men only) and HDL-cholesterol level (both sexes) and positively associated with total-cholesterol level (women only) and LDL-cholesterol level (both sexes), whereas no association was observed for BMI, WC, and HbA1c level. This study identified both positive and inverse associations of free sugars intake with cardiometabolic risk factors in Japanese adults.

Abstract
OBJECTIVE Associations between the overall quality of Japanese diets and metabolic risk factors are largely unknown. This cross-sectional study investigated this issue using data from the 2012 National Health and Nutrition Survey, Japan. METHODS Dietary intake was assessed by a 1-day weighed dietary record in 15,618 Japanese adults aged ≥ 20 years. Overall diet quality was assessed by adherence to the Japanese Food Guide Spinning Top (JFG score), its modified version (modified JFG score), the Mediterranean diet score (MDS) and the Dietary Approaches to Stop Hypertension (DASH) score. Metabolic risk factors included BMI, waist circumference, blood pressure, total, HDL- and LDL-cholesterol and glycated haemoglobin. RESULTS While DASH score was consistently associated with favourable nutrient intake patterns (including higher micronutrient and dietary fibre intakes and lower SFA and sodium intakes), other scores were associated with both favourable and unfavourable aspects (e.g., lower micronutrient intakes for JFG score, higher SFA intakes for modified JFG score and higher sodium intakes for MDS). The associations with metabolic risk factors were also inconsistent and unexpected, including positive associations of JFG and modified JFG scores with LDL-cholesterol, inverse associations of MDS with HDL-cholesterol and null associations of DASH score with blood pressure. CONCLUSIONS This study did not show expected and consistent associations of the four available diet quality scores with nutrient intakes and metabolic risk factors in Japanese adults. This in turn suggests the need for a scientific base on which to develop an appropriate tool for assessing the quality of diets in the Japanese context.

Abstract
BACKGROUND In recent years, individuals with high serum total cholesterol (TC) have been more likely to modify their diet by reducing their intake of dietary lipids. The aim of this study was to investigate time-related changes in the relationships between the Keys score, dietary lipids, and TC between 1980 and 2010 in representative Japanese populations. Methods and Results: We used 3 cross-sectional cohort studies conducted among Japanese representative populations in 1980, 1990, and 2010 (NIPPON DATA80/90/2010) for the analyses. We analyzed data for 10,365, 7,714, and 2,657 participants, respectively, in each dataset. The relationships between TC and the Keys score (calculated by dietary lipids, cholesterol, and energy intake)/dietary lipids were examined. In men, a 1-unit higher Keys score correlated with 0.92 mg/dL and 0.64 mg/dL TC in 1980 and 1990, respectively, but not in 2010. In women, a 1-unit higher Keys score correlated with 0.70 mg/dL and 0.74 mg/dL TC in 1980 and 1990, respectively, but with 0.33 mg/dL in 2010. In men and women, dietary cholesterol, saturated fatty acid (SFA), and trans fatty acid (TFA) levels were positively associated with TC concentrations in 1980 and 1990, but not in 2010. CONCLUSIONS In these representative Japanese populations, a higher Keys score as well as dietary cholesterol, SFA, and TFA levels correlated with higher TC concentrations in 1980/1990, but the relationships were weaker or not observed in 2010.

Abstract
Background The structure and risk factors for cardiovascular diseases (CVD) in Japan may change because lifestyle, particularly nutrition, socioeconomic status, and medical care, which affect CVD, may markedly change over time. Therefore, a new prospective cohort study on a representative general Japanese population based on national surveys is required. Methods In November 2010, the baseline survey of the National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 2010 (NIPPON DATA2010) was performed with the National Health and Nutrition Survey of Japan (NHNS2010) in 300 randomly selected districts throughout Japan. The survey included a questionnaire, electrocardiogram, urinalysis, and blood biomarkers added to the NHNS2010 examinations. Physical measurements, blood biomarkers, and dietary data were also obtained in NHNS2010. Socioeconomic factors were obtained by merging with the Comprehensive Survey of Living Conditions 2010 (CSLC2010) dataset. Participants are followed annually for the incidence of diabetes mellitus, CVD events (acute coronary events, heart failure, atrial fibrillation, and stroke), and cause-specific mortality. The activities of daily living are followed every 5 years. Results A total of 2,898 individuals aged 20 years or older agreed to participate in the baseline survey of NIPPON DATA2010. The participation rate was 74.6%. Of these, data from NHNS2010 was merged for 2,891 participants (1,236 men and 1,655 women). The data of 2,807 participants were also merged with CSLC2010 data. Conclusions We established NIPPON DATA2010 as a cohort study on a representative general Japanese population that covers all of Japan.

Abstract
Epidemiologic evidence on the associations between dietary acid load and metabolic risk factors are limited and inconsistent. We investigated the hypothesis that dietary acid load is associated with adverse profiles of metabolic risk factors in Japanese adults. This cross-sectional study included 15 618 Japanese adults aged ≥20 years from the 2012 National Health and Nutrition Survey, Japan. Dietary acid load was characterized as potential renal acid load (PRAL) and net endogenous acid production (NEAP) based on information on nutrient intake, which was derived from a 1-day semi-weighed dietary record. After adjustment for potential confounding factors, both PRAL and NEAP were positively associated with body mass index (BMI) and waist circumference in both sexes (P for trend ≤.01). PRAL and NEAP also showed positive associations with systolic and diastolic blood pressure in men, independently of BMI (P for trend ≤.005), while they showed positive associations with systolic (but not diastolic) blood pressure in women (P for trend ≤.03). For other metabolic risk factors, there were positive associations between PRAL and NEAP and total and LDL-cholesterol concentrations only in men (P for trend ≤.04). After excluding participants taking medication for hypertension, dyslipidemia, and diabetes, similar associations were observed for adiposity measures and blood pressure (P for trend ≤.01), with there being positive associations between NEAP and HDL-cholesterol and between PRAL and NEAP and glycated hemoglobin in men (P for trend ≤.04). In conclusion, higher dietary acid load was significantly but weakly associated with higher adiposity measures and blood pressure in Japanese adults.

Abstract
Objective We aimed to examine factors associated with untreated diabetes in a nationally representative sample of the Japanese population. Research Design and Methods We pooled data from the Japanese National Health and Nutrition Survey from 2005 to 2009 (n = 20,496). Individuals aged 20 years and older were included in the analysis. We classified participants as having diabetes if they had HbA1c levels ≥6.5% (≥48 mmol/mol). People with diabetes who self-reported that they were not currently receiving diabetic treatment were considered to be untreated. We conducted a multinomial logistic regression analysis to determine factors associated with untreated diabetes relative to non-diabetic individuals. Results Of 20,496 participants who were included in the analysis, untreated diabetes was present in 748 (3.6%). Among participants with untreated diabetes, 48.3% were previously diagnosed with diabetes, and 46.5% had HbA1c levels ≥7.0% (≥53 mmol/mol). Participants with untreated diabetes were significantly more likely than non-diabetic participants to be male, older, and currently smoking, have lower HDL cholesterol levels and higher BMI, non-HDL cholesterol levels, and systolic blood pressure. Conclusions A substantial proportion of people in Japan with untreated diabetes have poor glycemic control. Targeting relevant factors for untreated diabetes in screening programs may be effective to enhance the treatment and control of diabetes.
