RESUMO

BACKGROUND AND PURPOSE: An effect of dietary carotenes on risk of cardiovascular disease (CVD) is uncertain. We aimed to investigate whether the association between dietary carotenes intake and risk of CVD mortality will persist after controlling for the intakes of potential cardioprotective dietary factors that correlate with dietary alpha- and/or beta-carotenes. METHODS AND RESULTS: We followed up a total of 58,646 Japanese between 1988 and 1990 and 2009. We used a food frequency questionnaire (FFQ) to determine the dietary intakes of carotenes, and estimated the hazard ratios (HRs) and 95% confidence intervals (CIs) of CVD mortality in relation to carotene intake by the proportional hazard regression developed by David Cox. During 965,970 person-years of follow-up (median 19.3 years), we identified 3388 total CVD deaths. After adjusting for demographic and lifestyle factors, dietary intakes of alpha-carotene were significantly associated with the reduced risk of mortality from coronary heart disease (CHD); adjusted HR (95% CI) in the highest versus lowest quintiles of intake was 0.75 (0.58-0.96; P-trend = 0.02) and dietary intakes of beta-carotene were significantly associated with the reduced risk of mortality from CVD, CHD, and other CVD; adjusted HRs (95% CIs) were 0.88 (0.79-0.98; P-trend = 0.04), 0.78 (0.61-0.99; P-trend = 0.01), and 0.81 (0.67-0.98; P-trend = 0.04), respectively. However, after further adjusting for the dietary intakes of potassium, calcium, vitamins C, E, or K, these associations disappeared. CONCLUSIONS: -Dietary alpha- and beta-carotene intakes were not associated with risk of CVD mortality after controlling for intakes of other potential cardioprotective nutrients.

RESUMO

Dairy intake was suggested to reduce the risk of gastrointestinal cancers. This study investigated the association between dairy intake and the risk of pancreatic cancer (PAC) using a prospective cohort study and meta-analysis of prospective cohort studies. First, we included 59,774 people aged 40-79 years from the Japan Collaborative Cohort Study (JACC Study). The Cox regression was used to compute the hazard ratios (HRs) and 95% confidence intervals (CIs) of incident PAC for individuals who reported the highest intakes of milk, cheese, and yogurt compared with not consuming the corresponding dairy products. Then, we combined our results with those from other four prospective cohort studies that were eligible after searching several databases, in a meta-analysis, using the fixed-effects model before evaluating publication bias and heterogeneity across studies. In the JACC study, the highest versus no intakes of milk, cheese, and yogurt were not associated with the reduced risk of PAC after a median follow-up of 13.4 years: HRs (95% CIs)= 0.93 (0.64, 1.33), 0.91 (0.51, 1.62), and 0.68 (0.38, 1.21), respectively. The results did not significantly change in the meta-analysis: 0.95 (0.82, 1.11) for milk, 1.16 (0.87, 1.55) for cheese, and 0.91 (0.79, 1.05) for yogurt. The meta-analysis showed no signs of publication bias or heterogeneity across studies. To conclude, consumption of milk, cheese, and yogurt was not associated with the risk of PAC either in the JACC study or the meta-analysis.

RESUMO

BACKGROUND AND PURPOSE: Several prospective cohort studies and a randomized clinical trial have shown the beneficial effects of peanut consumption on cardiovascular disease and its risk factors. We examined the association between peanut consumption and risk of cardiovascular disease in Japanese men and women. METHODS: We analyzed data of 74 793 participants aged 45 to 74 years who completed a lifestyle questionnaire including the validated food frequency questionnaire in the Japan Public Health Center-based Prospective Study. They were followed up from 1995 to 2009 for cohort I and from 1998 to 1999 to 2012 for cohort II. Peanut consumption was calculated from the food frequency questionnaire, and the end points were incidence of stroke, ischemic heart disease, and cardiovascular disease (stroke and ischemic heart disease). RESULTS: During a median follow-up of 14.8 years, 3,599 strokes and 849 ischemic heart diseases were reported. Higher peanut consumption was associated with reduced risks of total stroke, ischemic stroke, and cardiovascular disease among men and women. The multivariable hazard ratios (95% CIs) for the highest versus lowest quartiles of peanut consumption after adjustment for age, sex, public health center, smoking, alcohol consumption, perceived stress level, physical activity, vegetable, fruit, fish, soy, sodium and total energy intakes, body mass index, history of hypertension, history of diabetes, and cholesterol-lowering drug were 0.84 (0.77-0.93, P for trend=0.002) for total stroke, 0.80 (0.71-0.90, P for trend=0.002) for ischemic stroke, 0.93 (0.79-1.08, P for trend=0.27) for hemorrhagic stroke, 0.97 (0.80-1.17, P for trend=0.81) for ischemic heart disease and 0.87 (0.80-0.94, P for trend=0.004) for cardiovascular disease, and these associations were similarly observed in both sexes. CONCLUSIONS: Higher peanut consumption was associated with reduced risk of stroke, especially ischemic stroke, but not ischemic heart disease in Japanese men and women.

RESUMO

Historically, a right bundle branch block has been considered a benign finding in asymptomatic individuals. However, this conclusion is based on a few old studies with small sample sizes. We examined the association between a complete right bundle branch block (CRBBB) and subsequent cardiovascular mortality in the general population in Japan. In this large community-based cohort study, data of 90,022 individuals (mean age, 58.5 ± 10.2 years; 66.2% women) who participated in annual community-based health check-ups were assessed. Subjects were followed up from 1993 to the end of 2016. Cox proportional hazards' models and log-rank tests were used for the data analysis. CRBBB was documented in 1,344 participants (1.5%). Among all included participants, CRBBB was associated with an increased risk of cardiovascular mortality after adjustment for all potential confounders (hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.06-1.38). The increased risk of cardiovascular mortality was particularly evident in women aged < 65 years (HR 2.00; 95% CI 1.34-2.98) and men aged ≥ 65 years (HR 1.28; 95% CI 1.06-1.55). CRBBB is associated with an increased risk of cardiovascular mortality in women aged < 65 years and men aged ≥ 65 years. Clinicians should be aware of the presence of CRBBB in young women and elderly men, even if they exhibit no symptoms.

RESUMO

AIM: Diabetes mellitus and hypertriglyceridemia may adversely interact with the development of ischemic cardiovascular disease, but epidemiological evidence on this issue is scarce. We hypothesized that the impact of hypertriglyceridemia on ischemic cardiovascular disease (ischemic heart disease and ischemic stroke) would differ according to the presence or absence of diabetes mellitus and tested our a priori hypothesis under a large population-based prospective study. METHODS: A total of 90,468 men and women aged 40-79 years in 1993 were enrolled in the Ibaraki Prefectural Health Study (IPHS), a community-based cohort study of Japanese. The participants' serum triglyceride levels (mostly nonfasting) were measured every 5 years, and the participants were followed up for mortality from ischemic cardiovascular disease through 2016. Hazard ratios (95% confidence intervals) were calculated according to 5-year updated triglyceride levels (<100, 100-149, 150-199, 200-299, and ≥ 300 mg/dl). RESULTS: During 1,795,877 person-years, there were 3,323 deaths from ischemic cardiovascular diseases (1,968 ischemic heart diseases and 1,355 ischemic strokes). We found no association between triglyceride levels and the risk of mortality from ischemic cardiovascular disease after adjustment for known cardiovascular risk factors. However, when stratified by the presence or absence of diabetes mellitus, excess mortality from ischemic cardiovascular disease appeared among participants with diabetes mellitus with triglyceride levels of ≥ 300 mg/dl. Further adjustment for high-density lipoprotein-cholesterol attenuated the association toward being statistically nonsignificant. CONCLUSION: The impact of high serum triglyceride levels on the risk of ischemic cardiovascular disease mortality was confined to participants with diabetes mellitus.

RESUMO

BACKGROUND AND AIMS: The role of hobbies as a protective factor against cardiovascular diseases (CVD) has gained increasing attention; however, no large-scale studies were performed to confirm this. We aimed to examine the association between having hobbies and the risk of total CVD, coronary heart disease (CHD), and stroke in a large Japanese cohort. METHODS: A total of 56,381 adults aged 45-74 years were divided into the non-hobby, having a hobby, and having many hobbies groups. We performed Cox proportional hazard models to estimate the hazard ratio (HRs) for incident CVD, CHD, and stroke after adjusting for potential confounding factors. RESULTS: We identified 3685 incident CVDs (940 CHDs and 2839 strokes) during a median follow-up of 16.3 years. After multivariable adjustment, compared to the non-hobby group, participants having a hobby and many hobbies had a 10% (HR = 0.90 [0.83, 0.97]) and 20% (HR = 0.80 [0.69, 0.93]) lower risk of CVD incidence, respectively. The risk of CHD was lower in those with many hobbies, but the association between having many hobbies and CHD risk was not statistically significant. We also found a similar inverse association for stroke. Compared to the non-hobby group, participants having a hobby and many hobbies had a 13% (HR = 0.87 [0.80, 0.96]) and 20% (HR = 0.80 [0.68, 0.94]) lower risk of stroke. CONCLUSIONS: Having hobbies was associated with a lower risk of CVD. Engagement in hobbies may emerge as an important target for healthy lifestyle promotion for the primary prevention of CVD.

RESUMO

BACKGROUND: The positive direct relation between stress and the development of cardiovascular disease has increasingly been recognized. However, the link between hypothalamic-pituitary-adrenal (HPA) dysregulation and subclinical cardiovascular disease has not been studied longitudinally. We investigated the relation of diurnal salivary cortisol, as a biological marker of stress levels, with progression of aortic stiffness over five years. METHODS: A total of 3281 people (mean age 65.5) in the Whitehall II prospective study provided six saliva samples on a single weekday. We assessed the diurnal salivary cortisol using the daytime slope and bedtime level. Aortic stiffness was measured by carotid-femoral pulse wave velocity (PWV) at baseline (2007-2009) and five years later (2012-2013). Linear mixed models were used to estimate the association of diurnal salivary cortisol with baseline PWV and five-year longitudinal changes. RESULTS: Diurnal salivary cortisol were not associated with PWV at baseline. Among women but not men, a 1-SD shallower salivary cortisol slope at baseline was associated with a five-year increase in PWV (ß = 0.199; 95% CI = 0.040, 0.358 m/s) and higher bedtime cortisol level (ß = 0.208, 95% CI = 0.062, 0.354 m/s). CONCLUSIONS: Dysregulation of the HPA axis measured using salivary cortisol (shallower slope, higher bedtime level) predicted the rate of progression of aortic stiffness among women.

RESUMO

AIMS: Reports on the association between height and aortic disease have been modest, and there are only a few studies investigating the association between height and mortality from specific aortic disease types or by sex. METHODS: We conducted the Japan Collaborative Cohort Study, a prospective study of 99,067 Japanese (41,730 men and 57,337 women) aged 40-79 years old. Height was self-reported, and the participants were followed up from 1988-1989 to the end of 2009. Sex-specific hazard ratios (95% confidence intervals) of mortality from aortic disease type according to sex-specific quartiles of height were analyzed using the Cox proportional hazards model. RESULTS: During the median follow-up period of 19.1 years, the numbers of deaths due to aortic aneurysm, thoracic aortic aneurysm, abdominal aortic aneurysm, and aortic dissection were 87, 29, 48, and 56 among men and 35, 17, 15, and 65 among women, respectively. The sex-specific multivariate hazard ratios (95% confidence intervals) and p for trend for the highest versus lowest quartiles of height were 1.10 (0.66-1.83), p=0.58 among men and 1.54 (0.85-2.79), p=0.06 among women for total aortic disease; 1.85 (0.80-4.28), p=0.16 among men and 5.67 (0.90-35.77), p=0.08 among women for abdominal aortic aneurysm; and 1.13 (0.48-2.64), p=0.65 among men and 1.70 (0.82-3.50), p=0.04 among women for aortic dissection. The positive association was observed for both sexes, albeit more prominent among women. No association was found between height and mortality from thoracic aortic aneurysms. CONCLUSIONS: As per our findings, we were able to determine that height was positively associated with mortality from abdominal aortic aneurysm in the Japanese population.

RESUMO

BACKGROUND: B vitamins and methionine are essential substrates in the one-carbon metabolism pathway involved in DNA synthesis and methylation. They may have essential roles in cancer development. We aimed to evaluate the associations of dietary intakes of vitamin B12, vitamin B6, folate, and methionine with the risk of esophageal cancer (EC) using data from the Japan Public Health Center-based Prospective Study. METHODS: We included 87,053 Japanese individuals who completed a food frequency questionnaire and were followed up from 1995-1998 to 2013 and 2015. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated by Cox proportional-hazard regression across quintiles of dietary intakes of B vitamins and methionine. RESULTS: After 1,456,678 person-years of follow-up, 427 EC cases were documented. The multivariable HR (95% CI) of incident EC in the highest versus lowest quintile of dietary intake of vitamin B12 was 1.75 (1.13-2.71; p-trend=0.01). Stratification analysis based on alcohol consumption showed that higher dietary intakes of vitamin B12 and methionine were associated with an increased risk of EC among never-drinkers; HRs (95% CIs) were 2.82 (1.18-6.74; p-trend=0.009; p-interaction=0.18) and 3.45 (1.32-9.06; p-trend=0.003; p-interaction 0.02) for vitamin B12 and methionine, respectively. Meanwhile, there was no association between vitamin B12 and methionine intake with the risk of EC among drinkers. There were no associations between dietary intake of folate or vitamin B6 and the risk of EC. CONCLUSION: Dietary intake of vitamin B12 was positively associated with the risk of EC in the Japanese population.

RESUMO

CONTEXT: Maternal cholesterol is important for fetal development. Whether maternal serum total cholesterol (maternal TC) levels in mid-pregnancy are associated with small- (SGA) or large- (LGA) for-gestational-age independent of pre-pregnancy body mass index (BMI) and weight gain during pregnancy is inconclusive. OBJECTIVE: To prospectively investigate the association between maternal TC in mid-pregnancy and SGA or LGA. DESIGN AND SETTING: The Japan Environment and Children's Study is a nationwide prospective birth cohort study in Japan. PARTICIPANTS: A total of 37,449 non-diabetic, non-hypertensive mothers with singleton birth at term without congenital abnormalities. OUTCOME MEASURES: Birth weight for the gestational age <10 percentile and ≥90 percentile were respectively defined as SGA and LGA by the Japanese neonatal anthropometric charts. RESULTS: The mean gestational age at blood sampling was 22.7±4.0 weeks. After adjustment for maternal age, sex of child, parity, weight gain during pregnancy, pre-pregnancy BMI, smoking, alcohol drinking, blood glucose levels, household income, and Study Areas, one standard deviation decrement of maternal TC was linearly associated with SGA [odds ratio (OR): 95% confidence intervals (CI) = 1.20: 1.15-1.25]. In contrast, one standard deviation increment of maternal TC was linearly associated with LGA [OR: 95% CI = 1.13: 1.09-1.16]. Associations did not differ according to pre-pregnancy BMI and gestational weight gain (p for interaction>0.20). CONCLUSION: Maternal TC levels in mid-pregnancy were associated with SGA or LGA in Japanese. Maternal TC in mid-pregnancy may help to predict SGA and LGA. Favorable maternal lipid profiles for fetal development must be explored.

RESUMO

OBJECTIVE: The present study investigated associations between occupation, job stress, and salivary cortisol levels after psychological tasks. METHODS: We examined 766 (273 men and 493 women) healthy employed Japanese participants aged 21 to 68 years (mean age = 46.4 years, standard deviation = 8.5) with three types of occupation: manager, teacher, and general worker. The Brief Job Stress Questionnaire was used to evaluate participants' job stress levels, including job demand, job control, support from supervisors, and support from coworkers. Salivary cortisol levels were measured at pre-session, post-stressful tasks, and post-relaxation. All samples were assayed using an enzyme-linked immunosorbent assay test. Natural log transformation was applied before statistical analyses. A multiple regression analysis and a repeated measures analysis of covariance were conducted to test associations between occupation and salivary cortisol levels, adjusting for confounding factors. Statistical analyses were conducted separately for men and women. RESULTS: Among both men and women, general workers had higher cortisol levels than managers throughout the experimental session (men 0.6 µg/dL and 0.4 µg/dL, respectively; women 0.5 µg/dL and 0.4 µg/dL, respectively). Job control was positively associated with cortisol levels measured in all sessions, after adjusting for confounding factors (standardized beta 0.15, 0.21, and 0.18 for pre-session, post-stressful-tasks, and post-relaxation, respectively, all p < 0.05). Men with low support from coworkers had higher cortisol levels than those with high support through the sessions (0.6 µg/dL and 0.4 µg/dL, respectively). CONCLUSION: Socioeconomic disparity according to occupational status was related to cortisol levels in Japanese workers. Support from coworkers may be effective for reducing cortisol secretion in men.

RESUMO

AIM: Reports have shown that physical activity is inversely associated with heart failure risk, but evidence in Asian populations is lacking. We sought to examine the impacts of walking and sports participation on heart failure mortality among a Japanese population. METHODS: We involved 36,223 Japanese men and 50,615 women (aged 40-79 years) who completed a self-administered questionnaire between 1988 and 1990. We divided participants into four categories of walking (<0.5, 0.5, 0.6-1.0, and ≥ 1 h/day) and sports participation (<1, 1-2, 3-4, and ≥ 5 h/week) and examined associations with activity and heart failure mortality through 2009. RESULTS: We found inverse associations between physical activity and heart failure mortality. The multivariable hazard ratios (95% confidence intervals) for the highest category of walking time compared with the second-lowest category were 0.76 (0.59-0.99) in men and 0.78 (0.61-0.99) in women, while the ratios for the highest category of sports participation time compared with the second-lowest category were 0.62 (0.41-0.93) in men and 1.09 (0.73-1.65) in women. The lower hazard ratios in the highest categories of walking and sports participation time in men became no longer statistically significant after excluding heart failure deaths for the first 5, 10, and 15 years for walking time and 10 and 15 years for sports participation. However, in women, the low hazard ratios for the highest category ≥ 1.0 h/day of walking time did not change materially. CONCLUSIONS: Physical activity was associated with a lower risk of mortality from heart failure in this Japanese community-based population. The attenuated and nonsignificant association of walking and sports participation with the risk in men after exclusion of first 5-15 years heart failure death was probably due to changes in physical activity and death certificate diagnosis during the follow-up and reverse causation. However, the persistent inverse association between walking and the risk in women suggests a beneficial preventive effect on heart failure.

RESUMO

Tocopherols, strong antioxidants, may be useful in preventing dementia, but the epidemiological evidence is insufficient. We performed a community-based follow-up study of Japanese, the Circulatory Risk in Community Study, involving 3739 people aged 40-64 years at baseline (1985-1999). Incident disabling dementia was followed up from 1999 through 2020. For subtype analysis, we classified disabling dementia into that with and that without a history of stroke. Dietary intake of tocopherols (total, α, ß, γ, and δ) were estimated using 24-h recall surveys. During a median follow-up of 19.7 years, 670 cases of disabling dementia developed. Total tocopherol intake was inversely associated with risk of disabling dementia with multivariable hazard ratios (95% confidence intervals) of 0.79 (0.63-1.00) for the highest versus lowest quartiles of total tocopherol intake (P for trend = 0.05). However, the association was strengthened when further adjusted for α-linolenic acid intake (Spearman correlation with total tocopherol intake = 0.93), with multivariable hazard ratios of 0.50 (0.34-0.74) (P for trend = 0.001) but was weakened and nonsignificant when further adjusted for linoleic acid intake (Spearman correlation with total tocopherol intake = 0.92), with multivariable hazard ratios of 0.69 (0.47-1.01) (P for trend = 0.05). Similar but nonsignificant inverse associations were observed for α-, γ-, and δ-tocopherols but not for ß-tocopherol. These results were similar regardless of the presence of a history of stroke. Dietary tocopherol intake was inversely associated with risk of disabling dementia, but its independent effect was uncertain owing to a high intercorrelation of α-linolenic linoleic acids with total tocopherol intake. Even with such confounding, a diet high in tocopherols may help prevent the onset of dementia.

RESUMO

BACKGROUND: Postpartum depression (PPD) has been associated with adverse health outcomes including maternal suicide. Mode of delivery has been suggested to be a risk factor for PPD, but no large cohort study has examined the association between mode of delivery and PPD. We aimed to examine the association between mode of delivery and risks of PPD at 1 and 6 months after childbirth. METHODS: In a nationwide study of 89,954 mothers with a live singleton birth, we examined the association between mode of delivery and risks of PPD. PPD was measured by the Edinburgh Postnatal Depression Scale (≥13) at 1 and 6 months after childbirth. Odds ratios (ORs) with 95% confidence intervals (CIs) of PPD were calculated using multivariable logistic regression analyses after adjustment of antenatal physical, socioeconomic, and mental factors. RESULTS: Among 89,954 women, 3.7% and 2.8% had PPD at 1 and 6 months after childbirth, respectively. Compared with unassisted vaginal delivery, cesarean section (CS) was marginally associated with PPD at 1 month, but not at 6 months; adjusted ORs were 1.10 (95% CI, 1.00-1.21) and 1.01 (95% CI, 0.90-1.13), respectively. The association with PPD at 1 month was evident in women with antenatal psychological distress: adjusted OR was 1.15 (95% CI, 1.03-1.28). The observed associations were attenuated after adjusting for infant feeding method. CONCLUSIONS: Women who had antenatal psychological distress and underwent CS delivery may be regarded as a target for monitoring PPD.

RESUMO

BACKGROUND: Ischemic stroke, including transient ischemic attack (TIA) and acute-phase cerebral infarction (aCI), is a serious health problem in the aging society. Thus, this study aimed to identify TIA and aCI biomarkers. METHODS: In 19 patients with TIA, candidate antigens recognized by serum IgG autoantibodies were screened using a human aortic endothelial cell cDNA library. Through amplified luminescent proximity homogeneous assay-linked immunosorbent assay (AlphaLISA), serum antibody levels against the candidate antigens were examined in healthy donor (HD), TIA, and aCI cohorts (n = 285, 92, and 529). The plasma antibody levels in the Japan Public Health Center-based Prospective Cohort Study (1991-1993) were also examined. RESULTS: The candidate antigens were aldolase A (ALDOA) and fumarate hydratase (FH). In AlphaLISA, patients with TIA or aCI had higher anti-ALDOA antibody (ALDOA-Ab) and anti-FH antibody (FH-Ab) levels than the HDs (P < 0.05). In a multivariate logistic regression analysis, the ALDOA-Ab (odds ratio [OR]: 2.46, P = 0.0050) and FH-Ab (OR: 2.49, P = 0.0037) levels were independent predictors of TIA. According to the case-control study, the ALDOA-Ab (OR: 2.50, P < 0.01) and FH-Ab (OR: 2.60, P < 0.01) levels were associated with aCI risk. In a correlation analysis, both ALDOA-Abs and FH-Abs were well associated with hypertension, coronary heart disease, and habitual smoking. These antibody levels also correlated well with maximum intima-media thickness, which reflects atherosclerotic stenosis. CONCLUSIONS: ALDOA-Abs and FH-Abs can be novel potential biomarkers for predicting atherosclerotic TIA and aCI.

RESUMO

In recent years, there has been an increase in the number of problems associated with neurodevelopmental disorders in children, and there has been a growing interest in the relationship between environmental chemicals and children's health. The objective of this study was to examine whether an association exists between occupational or environmental prenatal maternal exposure to volatile organic compounds and the risk of neurodevelopmental disorders in children using Japanese translations of the Ages & Stages Questionnaires, Third Edition (J-ASQ-3). An increase in the risk of neurodevelopmental delay in 12-month-old children associated with maternal exposure to formalin or formaldehyde was identified in terms of problem-solving (odds ratio (OR): 1.76, 95% confidence interval (CI): 0.99-3.12) and personal-social skills (OR: 3.32, 95% CI: 1.46-7.55). It is not clear whether or not this tendency is reversible, and whether it is observed past 12 months of age. Further research and a preventive approach are needed.

RESUMO

Cardiovascular disease (CVD) is the leading cause of death and a major contributor to disability worldwide. Since the majority of cardiovascular events are preventable, identification of modifiable CVD risk factors and implementation of primordial prevention strategies should be a public health priority. In this aspect, the American Heart Association declared a strategic goal to reduce total CVD mortality in the US by 20% within 10 years via eliminating 7 major CVD risk factors (hypertension, diabetes, dyslipidemia, cigarette smoking, physical inactivity, obesity, and poor-quality diet) in 2010, and their strategy has been achieving. However, the applicability of similar metrics to prevent CVD among East Asians requires an in-depth investigation of the modifiable CVD risk factors based on national and regional evidence-based findings. Herein, this review article aims to discuss several modifiable risk factors for CVDs, using epidemiological evidence from cohort studies and nationally representative data of 2 East Asian countries: Korea and Japan.

RESUMO

BACKGROUND/OBJECTIVES: Isothiocyanate (ITC) is formed via the hydrolysis of glucosinolates by myrosinase, found in cruciferous vegetables. Although myrosinase is inactivated by the cooking process, no studies have incorporated the effect of cooking into the estimation of dietary ITC intake or evaluated the validity. We evaluated the validity of dietary ITC intake estimated from a food frequency questionnaire (FFQ), and urinary ITC levels using 24 h urine samples or a WFR (weighed food record), and evaluated the reproducibility of dietary ITC in two FFQs administered at an interval of 1-year. SUBJECTS/METHODS: The JPHC-NEXT Protocol Area included a total of 255 middle-aged participants across Japan. We calculated dietary ITC intake from WFR and two FFQs by assuming that cooked cruciferous vegetables contain zero ITC. Urinary ITC excretion was measured at two points during summer and winter. The validity and reproducibility of dietary ITC intake estimated by FFQ were assessed using Spearman's correlation coefficients. RESULTS: Although we observed a moderate correlation between dietary ITC intake derived from a 12-day WFR and urinary ITC excretion, notwithstanding the cooking process, the correlation between dietary ITC intake estimated by FFQ and mean urinary ITC excretion was low. However, the correlation was improved when we compared urinary ITC excretion and a 3-day WFR or FFQ collected during winter. Our FFQ showed good reproducibility. CONCLUSION: Although seasonality is a critical factor, dietary ITC intake estimated using an FFQ showed moderate validity and reproducibility and can be used in future epidemiological studies.

RESUMO

The association between the intake of non-alcoholic beverages and CVD in Asians is uncertain. The intake of non-alcoholic beverages was estimated in 77 407 participants of the Japan Public Health Centre-based cohort study aged 45-74 years. The Cox regression calculated the hazard ratios (HR) and 95 % CI for incident CVD according to sex-specific quintiles of intake of non-alcoholic beverages. A total of 4578 incident CVD (3751 strokes and 827 CHD) were diagnosed during a 13·6-year median follow-up. The risks of stroke and total CVD were lower for the highest v. lowest intake quintiles of non-alcoholic beverages in men and women: the multivariable HRs (95 % CIs) were 0·82 (0·71, 0·93, Ptrend = 0·005) and 0·86 (0·76, 0·97, Ptrend = 0·02), respectively, in men and were 0·73 (0·63, 0·86, Ptrend = 0·003) and 0·75 (0·65, 0·87, Ptrend = 0·005), respectively, in women. The reduced risk was evident for both ischaemic and haemorrhagic strokes and was mainly attributable to green tea consumption. The intake of non-alcoholic beverages from coffee and other beverages was not associated with the risk of CVD in both men and women. Also, there was no association between the intake of non-alcoholic beverages and the risk of CHD in either sex. In conclusion, the risks of stroke and total CVD were lower with a higher intake of non-alcoholic beverages in Japanese men and women.
