Alcohol consumption and blood pressure: a comparison of native Japanese to American men

We compared the cross-sectional association of alcohol consumption with blood pressure in 810 Japanese men (JM) living in Tokyo and 946 white men (WM) living in New York. Mean systolic (JM and WM, p < 0.001) and diastolic blood pressure (JM, p < 0.002; WM, p < 0.001) were associated with alcohol consumption in both groups. Compared to abstainers, the heaviest drinkers had the highest systolic (JM, p = 0.001; WM, p < 0.01) and diastolic (JM, p < 0.002; WM, p < 0.05) blood pressures. The relation of blood pressure to alcohol intake was J-shaped in the Americans, but linear in the Japanese. Exploratory analyses revealed that the J-shape may have been due to under-reporting of heavy alcohol ingestion by American abstainers. When abstainers were excluded, the relationships were similar in both the American and Japanese. The positive association between blood pressure and alcohol consumption persisted after adjustment for age, cigarette smoking, use of antihypertensive medications, body mass index, heart rate, abdominal skinfold thickness, hematocrit, fasting blood glucose, serum uric acid levels and urinary sodium/potassium ratio. Alcohol use was also related to prevalence of hypertension. These findings confirm the presence of an independent association between alcohol intake and blood pressure in both JM and WM and suggest that, despite differences in the metabolism of alcohol, the relation of alcohol consumption to blood pressure is similar in both nationalities.     

儿童期血压偏高对成年期高血压的影响研究

目的 本研究旨在探讨儿童期血压偏高对成年期高血压的影响,为成人高血压的早期防控提供科学依据。方法 基于“中国居民健康与营养调查”资料(1991-2011年),纳入儿童期(6~17岁)和成年期(18~38岁)均进行至少1次随访的研究对象。儿童期血压偏高前期定义采用中国儿童青少年血压参考值性别和年龄的第90百分位(P₉₀)至第95百分位(P₉₅),儿童期血压偏高采用≥P₉₅。成年期高血压前期为收缩压/舒张压≥120/80 mmHg且<140/90 mmHg;成年期高血压为收缩压/舒张压≥140/90 mmHg,或有高血压史,或目前正服用降压药物。采用协方差分析和Cox比例风险回归模型分析儿童期血压偏高对成年期高血压前期和高血压的影响,控制混杂因素包括儿童期性别和年龄,成年期的体重指数(BMI)、吸烟和饮酒。结果 本研究共纳入1 984名数据完整的研究对象,中位随访时间为11.7年。基线儿童期共有108人(5.4%)为血压偏高前期,199人(10.0%)为血压偏高。随访成年期共有697人(35.1%)为高血压前期,104人(5.2%)为高血压。协方差分析表明,成年期收缩压和舒张压水平均随着儿童期血压百分位的增加而增加(P_趋势<0.001)。多因素Cox回归分析显示,儿童期血压偏高者成年后为高血压前期的风险增加(HR=1.41,95%CI:1.12~1.77)。儿童期血压偏高者成年后为高血压的风险显著增加(HR=1.73,95%CI:1.01~2.98)。结论 儿童期血压偏高会增加成年期罹患高血压的风险。应该重视儿童青少年血压监测,对血压偏高的高危儿童应及时采取干预措施。     

Association Between Exposure to Cadmium and Blood Pressure in Japanese Peoples

The authors studied the effects of environmental cadmium exposure on blood pressure (BP). Subjects 1,140 men and 1,713 women, aged ≥ 50 yr lived in three areas of Japan considered “unpolluted” by cadmium. Multiple logistic regression analysis was used to evaluate relationships between hypertension/nonhypertension and cadmium concentrations in blood (B-Cd) or urine (U-Cd). Age, body mass index, drinking and smoking habits, and blood and urine chemistry data were incorporated into the model. Odds ratios for hypertension were significantly less than 1 in either gender when U-Cd was the indicator of cadmium exposure and hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg. The results suggest a significant negative association between cadmium exposure and BP in inhabitants in Japan.     

Dietary Calcium and Blood Pressure in a Native American Population

Objective: To assess the relationship between dietary calcium and blood pressure.

Methods: Cross-sectional study of 404 adult Pima Indians of Arizona. Dietary variables were assessed by the 24-hour recall. Hypertension (HTN) was defined as systolic blood pressure (SBP) ≥140 mmHg or diastolic blood pressure (DBP) ≥90 mmHg or drug treatment.

Results: Controlled for age and sex, dietary calcium intake was higher in subjects with HTN than in those without (p<0.01), and higher dietary calcium was associated with a higher prevalence of HTN (odds ratio comparing highest with lowest tertile group of calcium=2.6, 95% CI 1.4–4.8). Age-sex-adjusted mean DBP in low, middle and high tertiles of calcium was 74, 76, and 79 mmHg, respectively (p<0.001). SBP was not significantly different in the three tertiles (p=0.07). Multiple regression analyses that controlled for age, sex, body mass index, sodium, potassium and alcohol also suggested a positive association between DBP and dietary calcium (p<0.01), an association which was stronger at higher glucose concentrations (p<0.01 for the calcium-glucose interaction).

Conclusion: In Pima Indians, a population with a high incidence of diabetes, the inverse association between dietary calcium and blood pressure reported in other populations was not found.     

Fruit and vegetable consumption is inversely associated with blood pressure in a Mediterranean population with a high vegetable-fat intake: the Seguimiento Universidad de Navarra (SUN) Study

There is evidence that a diet rich in fruit and vegetables reduces blood pressure (BP). Characteristically, the Mediterranean diet is rich in plant-derived foods and also in fat, but studies conducted in Mediterranean countries to relate diet to BP are scarce. We studied the association between fruit and vegetable consumption and BP in a cross-sectional analysis of 4393 participants in the Seguimiento Universidad de Navarra (SUN) Study, an ongoing dynamic cohort study in Spain. Diet was measured using a food-frequency questionnaire previously validated in Spain. Fat represented more than 37 % total energy intake. Subjects were considered to have undiagnosed hypertension if they reported systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg, and not a medical diagnosis of hypertension. The adjusted prevalence odds ratio of undiagnosed hypertension (upper v. lowest quintile) was 0.58 (95 % CI 0.36, 0.91; P for trend 0.01) for vegetable consumption and 0.68 (95 % CI 0.43, 1.09; P for trend 0.10) for fruit consumption. Comparing those in the highest quintile of both fruit and vegetable consumption with those in the lowest quintile of both food groups, the prevalence odds ratio was 0.23 (95 % CI 0.10, 0.55; P = 0.001), after adjusting for risk factors for hypertension and other dietary exposures. In a Mediterranean population with an elevated fat consumption, a high fruit and vegetable intake is inversely associated with BP levels.     

Does alcohol protect against ischaemic heart disease in Bulgaria? A case-control study of non-fatal myocardial infarction in Sofia

BACKGROUND: Many observational studies have shown that alcohol consumption is associated with a reduced risk of ischaemic heart disease (IHD). IHD mortality has generally fallen in established market economies but not in some countries of Eastern Europe. Since the level of consumption of saturated fat does not explain these differences in trends, other associations with risk need to be explored. We investigated whether alcohol consumption also presents a U or J-shaped association with IHD risk in a case-control study in Bulgaria. METHODS: Cases (n = 155) were admissions to the cardiology unit, Central Clinical Hospital, Sofia, aged 45 to 69, with confirmed diagnoses of ischaemic heart disease. Controls (n = 154) were concurrent admissions for minor elective surgery. Measurements were made of blood pressure, height and weight and a blood sample was taken around three days after admission. Subjects were interviewed before discharge and asked about the type and amount of alcohol they consumed. RESULTS: Reported alcohol intake demonstrated a J-shaped association with the risk of IHD. The odds ratio (adjusted only for age and sex) was 0.67 (95% CI 0.34-1.28) for patients reporting 0.01-18 g/d of alcohol consumption daily, and 0.36 (95% CI 0.18-0.73) for 18.01-36 g/d, compared to patients reporting to be abstainers. The associations with alcohol intake remained statistically significant and unaltered after adjustment for established IHD risk factors: HDL cholesterol, body mass index, systolic blood pressure, family history, education, physical activity and risk factors significantly related with IHD: fruit and vegetables consumption, type of fat used in cooking, bread consumption. CONCLUSIONS: Our results are consistent with previous studies showing a J-shaped association between alcohol intake and IHD risk. The highest protective effect we observed for levels of alcohol intake 18.01-36 g/d, which corresponds to 100-200 ml wine or 1-2 beers, or little more than 50-100 ml spirits.     

Association of dietary sodium intake and blood pressure in the German population

Aim

The present study investigated the association of dietary sodium intake and blood pressure (BP) based on existing data from the German National Health Interview and Examination Survey (GNHIES) and the associated German Nutrition Survey (GeNuS).

Subject and methods

After exclusion of participants with known hypertension and/or anti-hypertensive medication use, complete data of the GeNuS subsample of the 1998 GNHIES were analysed for 1,539 men and 1,553 women aged 18–79?years. The survey included a health and lifestyle questionnaire, a medical examination and a comprehensive diet history interview. Sodium density (g/1,000?kcal) was examined in quartiles of systolic and diastolic BP (SBP and DBP). Multiple linear regression models were used to investigate associations of sodium density and SBP or DBP. Adjustments were made for sex, age and socio- and health-behavioral risk factors previously found to be related to BP in univariate analysis.

Results

Participants with a high SBP and DBP (fourth quartile of SBP: ≥ 142?mmHg in men; ≥ 139?mmHg in women) had a significantly higher dietary sodium intake than individuals with a lower BP. In the multiple models, both SBP and DBP were significantly associated with sodium density when adjusted for other factors such as sex, age, body mass index and alcohol consumption.

Conclusion

An association of dietary sodium intake and BP in the German population could be found. Further research using sodium data collected via 24-h urine samples is urgently needed for evidence-based public health policy reducing risk of BP associated morbidities and mortalities in Germany.     

Association between exposure to cadmium and blood pressure in Japanese peoples

The authors studied the effects of environmental cadmium exposure on blood pressure (BP). Subjects 1140 men and 1713 women, aged > or =50 yr lived in three areas of Japan considered "unpolluted" by cadmium. Multiple logistic regression analysis was used to evaluate relationships between hypertension/nonhypertension and cadmium concentrations in blood (B-Cd) or urine (U-Cd). Age, body mass index, drinking and smoking habits, and blood and urine chemistry data were incorporated into the model. Odds ratios for hypertension were significantly less than 1 in either gender when U-Cd was the indicator of cadmium exposure and hypertension was defined as systolic BP > or =140 mmHg and/or diastolic BP > or =90 mmHg. The results suggest a significant negative association between cadmium exposure and BP in inhabitants in Japan.     

Alcohol consumption, drinking pattern and blood pressure: analysis of data from the Italian National Research Council Study

The present analyses addressed the relationship between alcohol consumption, drinking patterns and hypertension in 6699 Italian men and women participating in a national project on arteriosclerosis risk factors. The results of the analyses are consistent with an association between heavy alcohol consumption and systolic blood pressure in both males and females. Higher diastolic blood pressure was associated with heavy alcohol consumption in men but not in women. Drinkers of wine both with and without meals have a higher prevalence of hypertension than abstainers in both sexes. We conclude that heavy alcohol consumption is associated with higher blood pressure values, and that the pattern of drinking could be an important determinant in the association between alcohol and hypertension.     

北京市宣武区成人饮酒与慢性病关系研究

目的探讨饮酒与高血压病、糖尿病、血脂异常、肥胖的关系。方法采用多阶段分层整群随机抽样的方法,对742名居民进行问卷调查、体格检查和实验室检测,分析饮酒与慢性病的关系。结果过量饮酒会使血压升高、导致腹型肥胖、甘油三酯升高;低频率饮酒(1～3 d/月)组慢性病患病率最低,随饮酒频率的增加,慢性病的患病率也有所增加;与小剂量组(<500 g/月)相比,大剂量饮酒组(≥500 g/月)高血压和肥胖发生率提高,高血压患病率由37.3%上升到57.3%,肥胖发生率由46.1%上升到67.1%,差异有统计学意义。Logistic回归分析显示,饮酒频率越高则慢性病的患病风险越大(OR=1.648)。结论低频率少量饮酒对高血压、糖尿病、血脂异常及肥胖有保护作用;长期、高频率、大量饮酒会导致慢性疾病的发生。     

Alcohol consumption, %CDT, GGT and blood pressure change during alcohol treatment

AIMS: Blood pressure (BP) changes in alcohol-dependent individuals during a 12-week alcohol relapse prevention study were examined in light of drinking status and biomarkers of alcohol consumption [carbohydrate-deficient transferrin (%CDT) and gamma-glutamyl transpeptidase (GGT)]. METHODS: Of 160 randomized alcoholic individuals, 120 who had hypertension and in whom daily drinking data was available, at 6 and 12 weeks of treatment were included. The impact of alcohol consumption on change in systolic BP (SBP) and diastolic BP (DBP) was examined. Further analysis determined the relationship between BP and alcohol-use biomarkers. RESULTS: A significant effect of complete abstinence on both SBP (-10 mmHg; P = 0.003) and DBP (-7 mmHg; P = 0.001) when compared to any drinking (SBP and DBP = -1 mmHg) was observed. At week 12, participants with a positive %CDT (> or =2.6) had 7 mmHg greater SBP (P = 0.01) and DBP (P < 0.001) than those with negative %CDT. Participants with positive GGT (> or =50 IU) had 10 mmHg greater SBP (P = 0.12) and 9 mmHg greater DBP (P = 0.03) than those with negative GGT. The percent change in SBP was correlated with percent change in %CDT (P = 0.003) but not GGT (P = ns). The percent change in DBP was correlated with both percent change in %CDT (P < 0.0001) and GGT (P = 0.03). CONCLUSIONS: Abstinence from alcohol significantly decreased the BP and a positive relationship between BP and both alcohol-use biomarkers was illustrated. Since %CDT is more specific than GGT for heavy alcohol consumption, clinicians may monitor the role of alcohol in hypertension using %CDT as a supplemental aid, providing an objective assessment of drinking to influence BP treatment decisions.     

Arsenic exposure from drinking water, dietary intakes of B vitamins and folate, and risk of high blood pressure in Bangladesh: a population-based, cross-sectional study

The authors performed a cross-sectional analysis to evaluate the association between arsenic exposure from drinking water and blood pressure using baseline data of 10,910 participants in the Health Effects of Arsenic Longitudinal Study in Bangladesh (October 2000-May 2002). A time-weighted well arsenic concentration (TWA) based on current and past use of drinking wells was derived. Odds ratios for high pulse pressure (> or = 55 mmHg) by increasing TWA quintiles (< or = 8, 8.1-40.8, 40.9-91.0, 91.1-176.0, and 176.1-864.0 microg/liter) were 1.00 (referent), 1.39 (95% confidence interval (CI): 1.14, 1.71), 1.21 (95% CI: 0.99, 1.49), 1.19 (95% CI: 0.97, 1.45), and 1.19 (95% CI: 0.97, 1.46). Among participants with a lower than average dietary intake level of B vitamins and folate, the odds ratios for high pulse pressure by increasing TWA quintiles were 1.00 (referent), 1.84 (95% CI: 1.07, 3.16), 1.89 (95% CI: 1.11, 3.20), 1.83 (95% CI: 1.09, 3.07), and 1.89 (95% CI: 1.12, 3.20). The odds ratios for systolic hypertension suggest a similar but weaker association. No apparent associations were observed between TWA and general or diastolic hypertension. These findings indicate that the effect of low-level arsenic exposure on blood pressure is nonlinear and may be more pronounced in persons with lower intake of nutrients related to arsenic metabolism and cardiovascular health. Future research is needed to evaluate the effect of low-level arsenic exposure on specific cardiovascular outcomes.     

Interrelations among smoking habits, casual blood pressure and intraocular pressure in middle and old-aged Japanese residents

Objectives To investigate the association of smoking habits with blood pressure (BP) and intraocular pressure (IOP), and to examine whether the smoking-BP association is related to the IOP level. Methods This study was conducted on the basis of a cross-sectional design using annual health check-up data during one-year between August, 1999 and August, 2000 for 611 middle and old-aged Japanese residents living in Ibaraki prefecture, Japan. Results After adjustment for age, gender, body mass index and alcohol intake score, the proportion of hypertensives, and the mean systolic and diastolic blood pressure (SBP and DBP) of the subjects without antihypertensive medications were the highest (50.4%, 129.6 mmHg and 75.9 mmHg, respectively) in the “smokers of 25 or more cigarettes per day with intraocular pressure (IOP)≥15 mmHg” of six subgroups crossed by three smoking categories (non-smokers, 1 to 24 cigarettes per day, and 25 or more cigarettes per day) and two IOP categories (less than 15 mmHg, and 15mmHg or greater). On the other hand, the adjusted proportion of hypertensives, and the adjusted mean SBP and DBP decreased with increasing smoking category in the individuals with less than 15 mmHg of the IOP (p for trend=0.028 for proportion of hypertensives 0.008 for the SBP, and 0.001 for the DBP, respectively). Conclusions Heavy smoking may be specifically related to ‘high BP accompanied by high IOP’, although the BP may be inversely associated with smoking under the condition without high IOP.     

Lifestyle and the development of hypertension: a 3-year follow-up study of middle-aged Japanese male office workers.

The association of lifestyle factors with the development of hypertension (blood pressure > or = 140/90 mmHg) over a 3-year follow-up period was studied in 949 hypertension-free Japanese male office workers aged 35 to 54 years. From the Cox proportional hazards model, age, alcohol intake, body mass index (BMI) and hours of work were independent factors associated with the development of hypertension. Adjusted hazard ratios for 5-year increases in age, daily consumption of alcohol, 5-kg/m2 increases in BMI and working 10 hours per day or more were 1.18 [95% confidence interval (CI) = 1.02-1.35]; 1.53 (CI = 1.14-2.05); 1.79 (CI = 1.38-2.33) and 0.58 (CI = 0.41-0.82), respectively. In the analysis using logistic regression, BMI was independently related to working 10 hours per day or more, controlling for other lifestyle factors. Adjusted odds ratio for 5-kg/m2 increase in BMI was 0.66 (CI = 0.49-0.88). These results suggest that the influences of long working hours on blood pressure are likely to be indirectly mediated through less overall obesity.     

Association between cigarette consumption and proteinuria in healthy Japanese men and women from an occupational population

The association between cigarette consumption and prevalence of mild proteinuria (30-99 mg/dl of albumin) was analyzed in 11,569 male and 4,715 female workers aged 18-67 yr recruited from an occupational population. Proteinuria was found in 274 (2.4%) of the total male workers and in 50 (1.1%) of the total females. Stepwise logistic regression analyses showed that sex, suspected diabetes mellitus, blood pressure (BP) and Brinkman Index (BI) levels (0, 1-199, 200-499, 500-799, 800-) were significantly related to proteinuria, and that the odds ratio of each BI level for proteinuria was 1.11 (C.I.: 1.01-1.67). In the subjects aged 50 yr or older, after excluding those suspected of having hypertension and/or diabetes mellitus, the odds ratio reached 1.37 (C.I.: 1.15-1.63), with the gender difference then no longer significant. The odds ratio for proteinuria was calculated as 5.44 (C.I.: 2.27-13.0) in male and female smokers having a BI of 500 or above and normal-high BP (130-139/85-89 mmHg) in comparison with nonsmokers having normal BP (<130/85 mmHg). These results suggest that heavy cigarette consumption represented by a BI of 500 or above is a risk factor of proteinuria even in healthy Japanese workers, particularly in those aged 50 yr or older and having normal-high BP.     

Sex and age interactions in the association between alcohol and blood pressure

The cross-sectional association between alcohol intake and blood pressure was examined in a probability sample of Michigan adults surveyed in 1983. Despite adjustments for race, sex, age, Quetelet index, and current treatment with antihypertensive medications, heavier alcohol intakes (more than one drink daily) were associated with increased systolic blood pressure, diastolic blood pressure, and prevalence of elevated blood pressure. These associations were somewhat exaggerated in women and in younger persons. Statistically significant differences in blood pressure were demonstrated only among consumers of more than one drink daily. Attributable risk calculations indicated that no more than 8.4 and 8.5% of instances of elevated blood pressure (systolic pressure greater than or equal to 140 mmHg or diastolic pressure greater than or equal to 90 mmHg) in men and women, respectively, could be attributed to alcohol intakes exceeding one drink daily.     

Gender and age differences in lifestyle factors related to hypertension in middle-aged civil service employees

The aim of this study is to identify lifestyle factors related to hypertension in man and woman workers, and to investigate age and gender differences in the relationships of the factors. From 6,000 civil service employees (4,937 men and 1,063 women) aged 40-69 years, information on lifestyle-related factors such as stress, exercise habits, preference for salty taste, alcohol drinking and smoking habits, and body mass index, as well as age and family history of hypertension was obtained through self-administered questionnaires in 1997. Hypertension was defined as either a systolic blood pressure > or = 140 mmHg, a diastolic blood pressure > or = 90 mmHg, or undergoing treatment for hypertension, and was present by 37.0% in men and 19.6% in women. Only body mass index was a significant lifestyle-related risk factor common to both genders with an odds ratio and its 95% confidence interval in parentheses of 2.2 (2.0-2.5) for men and 3.2 (2.3-4.6) for women. Men and women who preferred salty taste showed multivariate adjusted odds ratios of 0.9 (0.8-1.1) and 1.5 (1.1-2.2) for hypertension, respectively. In the stratified subanalysis, women aged 50 years and over had a significant odds ratio of 2.7 (1.5-4.9), whereas women aged 40-49 years and men of all age classes failed to show significant relationships. Salt intake was suggested to be a key factor for hypertension particularly for women after menopause.     

Poor health is associated with episodic heavy alcohol use: evidence from a National Survey

OBJECTIVES: The objective of this study was to examine the relationship between self-rated health and episodic heavy drinking in a representative sample of American adults. We also sought to determine ethnic and gender differences in the association between self-rated health and episodic heavy drinking. METHODS: Data (n=4649) from the Third US National Health and Nutrition Examination Survey were utilized for this investigation. Episodic heavy drinking was defined as the consumption of five or more and four or more alcoholic beverages on one occasion for men and women, respectively. Poor health was defined as answering fair or poor to the question: "Would you say your health in general is excellent, very good, good, fair or poor?" Odds ratio from the logistic linear regression analysis was used to estimate the risk for poor health that was associated with episodic heavy drinking. Statistical adjustments were made for age, hypertension, diabetes, current smoking, body mass index and race/ethnicity. RESULTS: Overall, episodic heavy drinking was associated with increased odds of poor self-rated health in men and women. In men, episodic heavy drinking was independently associated with 1.28 (95% CI: 1.07-1.82) increased odds of poor health. The corresponding value in women was 1.86 (95% CI: 1.05-2.28). In men, being Black was associated with approximately two-fold (OR=1.96; 95% CI: 1.33, 2.89), and being Hispanic was associated with approximately four-fold (OR=3.59; 95% CI: 2.50, 5.14) increased odds of poor self-rated health relative to being White. The corresponding odds ratios in women were 2.97 (95% CI: 1.90, 4.64) and 5.18 (95% CI: 3.23, 8.30). Associations were greater among blacks (adjusted OR=2.41; 95% CI: 1.81-3.22) and Hispanics (adjusted OR=4.15; 95% CI: 3.12-5.52) than among whites. CONCLUSIONS: Poor health is associated with episodic heavy alcohol consumption. Public health strategies to curb alcohol abuse may improve self-reported health status in these at-risk populations.     

Association between the Intake of Fermented Soy Products and Hypertension Risk in Postmenopausal Women and Men Aged 50 Years or Older: The Korea National Health and Nutrition Examination Survey 2013–2018

Sodium intake is positively associated with hypertension risk; however, it is not clear whether there is an association between the intake of fermented soy products, a major source of salt, and blood pressure (BP). This study aimed to investigate the hypothesis that hypertension risk and BP were negatively associated with the intake of fermented soy products but not with the intake of sodium from fermented soy products. This cross-sectional study was performed using data from the Korea National Health and Nutrition Examination Survey (2013–2018). In total, 11,566 men and postmenopausal women aged ≥50 years were divided according to quintiles of sodium or fermented soy product intake. The intake of fermented soy products was negatively associated with hypertension risk (odds ratio: 0.81, 95% confidence interval: 0.66–0.98; p-trend = 0.023) and systolic BP (SBP; p-trend = 0.043) in postmenopausal women. Mediation analysis showed that the intake of fermented soy products had total and direct effects on SBP; however, there was no indirect effect because soy nutrients, such as protein, fiber, calcium, and potassium, had no significant effects on SBP. Among men, fermented soy product intake was not associated with hypertension risk and BP. Additionally, the intake of sodium from fermented soy products was not significantly associated with hypertension risk and BP in both postmenopausal women and men. This study suggests that hypertension risk and BP were not associated with the intake of sodium from fermented soy products; further, hypertension risk and BP were inversely associated with fermented soy product intake in postmenopausal women. Further clinical studies are needed to confirm the effect of fermented soy product intake on hypertension risk and BP.     

Health risk behaviours, awareness, treatment and control of hypertension among rural community people in Thailand

This cross-sectional study aimed to assess health risk behaviours, prevalence, awareness, treatment, and control of hypertension and associated factors among Thai rural community people. 527 people, aged 35-60 years, were randomly sampled and interviewed. Two blood pressure (BP) measurements were assessed by standardized protocol. Hypertension was defined as a mean systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg. 76.9% lacked regular exercise, 28.5% were current alcohol drinkers, and 23.7% were current smokers. The prevalence of hypertension was 17.8%. Among the hypertensive cases, 64.9% (61/94) were aware of their high BP, 42.6% (26/61) were treated, and 42.3% (11/26) achieved BP control (< 140/ 90 mmHg). Multiple logistic regression analysis indicated four variables significantly associated with hypertension: age > 40 years (adjusted OR = 4.20, 95% CI 1.93-9.11), married status (adjusted OR = 0.48, 95% CI 0.26-0.89), family history of hypertension (adjusted OR = 2.39, 95% CI 1.40-4.07), and BMI > 23.0 kg/m2 (adjusted OR = 3.41, 95% CI 1.80-6.45). Lifestyle modification programs are needed to prevent hypertension.
