Achievement status toward goal blood pressure levels and healthy lifestyles among Japanese hypertensive patients; cross-sectional survey results from Fukushima Research of Hypertension (FRESH)

Association of healthy lifestyle score with control of hypertension among treated and untreated hypertensive patients: a large cross-sectional study

Background

Hypertension stands as the leading single contributor to the worldwide burden of mortality and disability. Limited evidence exists regarding the association between the combined healthy lifestyle score (HLS) and hypertension control in both treated and untreated hypertensive individuals. Therefore, we aimed to investigate the association between HLS and hypertension control among adults with treated and untreated hypertension.

Methods

This cross-sectional study, including 311,994 hypertension patients, was conducted in Guangzhou using data from the National Basic Public Health Services Projects in China. The HLS was defined based on five low-risk lifestyle factors: healthy dietary habits, active physical activity, normal body mass index, never smoking, and no alcohol consumption. Controlled blood pressure was defined as systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg. A multivariable logistic regression model was used to assess the association between HLS and hypertension control after adjusting for various confounders.

Results

The HLS demonstrated an inverse association with hypertension control among hypertensive patients. In comparison to the low HLS group (scored 0-2), the adjusted odds ratios (95% confidence intervals) for hypertension were 0.76 (0.74, 0.78), 0.59 (0.57, 0.60), and 0.48 (0.46, 0.49) for the HLS groups scoring 3, 4, and 5, respectively (Ptrend < 0.001). Notably, an interaction was observed between HLS and antihypertensive medication in relation to hypertension control (Pinteraction < 0.001). When comparing the highest HLS (scored 5) with the lowest HLS (scored 0-2), adjusted odds ratios (95% confidence intervals) were 0.50 (0.48, 0.52, Ptrend < 0.001) among individuals who self-reported using antihypertensive medication and 0.41 (0.38, 0.44, Ptrend < 0.001) among those not using such medication. Hypertensive patients adhering to a healthy lifestyle without medication exhibited better blood pressure management than those using medication while following a healthy lifestyle.

Conclusion

HLS was associated with a reduced risk of uncontrolled blood pressure.

Association between Health Practice and Food Stockpiling for Disaster

In this study investigated the association between health practices and food stockpiling for disasters in predicted areas with a high risk of food shortage due to the Nankai Trough earthquake. A survey was conducted during 18-20 December 2019 using a self-administered web-based questionnaire. In total, 1200 individuals registered with an online survey company participated in the study. The association between health practices and food stockpiling status was analyzed (n = 998). 59.1% of participants had a poor Breslow's seven health practice scores (BHPS), 32.9% had a moderate score, and 8.0% had a good score. Multivariable logistic regression analysis revealed that higher BHPS had a significantly higher prevalence of food stockpiling. Additionally, the interrupted group had the highest percentage of participants with low BHPS. Lower BHPS was significantly associated with interrupted stockpiled in the adjusted models. Among the seven health practices, the odds ratio of the "eating breakfast" practice was high. There was a significant positive association between higher health practice scores and food stockpiling for disasters in areas with a high risk of food shortage due to the predicted earthquake. Particularly, it was clarified that individuals who had fewer good health practices were associated with ending up interrupting food stockpiling.

An association between visceral or subcutaneous fat accumulation and diabetes mellitus among Japanese subjects

BACKGROUND

The impact of subcutaneous fat accumulation remains controversial. This study assessed the association between visceral or subcutaneous fat area (VFA and SFA, respectively) and diabetes mellitus (DM) among Japanese subjects.

METHODS

This was a cross-sectional study involving 1907 eligible participants (men, 1050; women, 857) who participated in a voluntary health check-up conducted at Juntendo University Hospital from January 2017 to December 2018, in Tokyo, Japan. Associations between VFA or SFA quartiles and DM were identified using adjusted odds ratios (AORs) and 95% confidence intervals (CIs) with multivariable logistic regression analysis adjusted for confounders. Receiver operating characteristic (ROC) curve analysis was used to assess appropriate cut-off values of VFA or SFA.

RESULTS

Multivariate analyses showed that Q4 (≥ 125 cm²) of VFA was significantly positively associated with DM compared to Q1 (< 65 cm²) (AOR = 1.94, 95% CI 1.02-3.71), whereas there was no association between SFA and DM in men. Among women, Q4 (≥ 85 cm²) of VFA was significantly positively associated with DM compared to Q1 (< 30 cm²) (Q4, AOR = 6.15, 95% CI 1.65-22.99). Also, Q3 and Q4 (≥ 135 cm²) of SFA were significantly positively associated with DM compared to Q1 (< 90 cm²) (Q3, AOR = 5.64, 95% CI 1.21-26.25; Q4, AOR = 7.81, 95% CI 1.71-35.65). The appropriate cut-off value of VFA in men was 101.5 cm². Those of VFA and SFA in women were 72.5 cm² and 165.3 cm², respectively.

CONCLUSIONS

Our results suggest the importance of considering SFA as well as VFA, especially in women, for primary and secondary prevention of DM.

Association between Visceral or Subcutaneous Fat Accumulation and B-Type Natriuretic Peptide among Japanese Subjects: A Cross-Sectional Study

Background: Some previous studies have shown reduced levels of plasma B-type natriuretic peptide (BNP) in individuals with obesity. We aimed to estimate the relationship between BNP and abdominal fat distribution, adjusted for confounding factors. Methods: This cross-sectional study included 1806 Japanese individuals (981 men and 825 women) who underwent a medical health check-up. Analyzed data included age, sex, visceral fat area (VFA), and subcutaneous fat area (SFA) as obtained from computed tomography, blood pressure, and blood test results including BNP. Multiple linear regression analysis was used to examine the association between BNP, VFA, and SFA after adjusting for age, sex, comorbidities, and body mass index. Results: In the models analyzed separately for VFA and SFA, BNP correlated independently with VFA in multiple linear regression analysis among all subjects and in both men and women, while SFA correlated inversely with BNP in all subjects and women but not in men. In the model that included both VFA and SFA, BNP correlated independently with VFA, but SFA and BNP were not correlated in any models. Conclusion: Higher VFA showed an independent, significant association with lower BNP. In addition, the inverse correlation with BNP was stronger for VFA than for SFA.

An impact of dietary intervention on blood pressures among diabetic and/or hypertensive patients with high cardiovascular disorders risk in northern Thailand by cluster randomized trial

BACKGROUND

Global sodium intake remains above the recommended levels to control blood pressure (BP). We aimed to evaluate the efficacy of a dietary intervention on BP through salt reduction among community-dwelling participants with high risk of cardiovascular disorders (CVD).

METHODS

This cluster randomized trial (February 2012 to January 2013) included cooking instruction using the pocket salt meter among patients with diabetes and/or hypertension who were treated at health center in Thailand. Based on health centers, 8 clusters of eligible participants were randomly allocated to the 4 intervention and 4 control groups. Dietary intervention was performed at baseline, 1 month, and 3 months in intervention group. In both groups, systolic and diastolic BPs, and estimated 24 hours salt intake based on overnight urine samples were measured at baseline, 6 months, and 12 months.

RESULTS

A total of 753 participants were enrolled (374 in the intervention group and 379 in the control group). In the mixed-effects model, there were significant difference in SBP and estimated salt intake after adjusting covariates at 6 months (adjusted differences between groups [95% CI]; -7.55 [-5.61 to -9.49] mm Hg P < .01; -0.66 [-0.40 to -0.92] g/day P = .03). However, these differences were not observed at 12 months (adjusted differences between groups [95% CI]; -1.83 [0.34 to -4.00] mm Hg P = .48; -0.42 [-0.17 to -0.67] g/day P = .16). There were no differences in DBP in both follow-ups.

CONCLUSIONS

These results may suggest the effectiveness of a visually based dietary intervention targeting salt intake reduction in short term, but the effectiveness discontinued in long term.Clinical trial number: The International Standard Randomized Controlled Trial Number Register (ISRCTN39416277) on January 3, 2012.

Serum zinc concentrations and characteristics of zinc deficiency/marginal deficiency among Japanese subjects

BACKGROUND

Studies that have examined serum zinc deficiency/marginal deficiency in developed countries, including Japan, are still limited. The aim of this study was to assess serum zinc concentrations and associated characteristics among Japanese subjects.

METHODS

This cross-sectional study, conducted from September 2016 to December 2018, included 2056 eligible subjects who participated in a voluntary health checkup. Serum zinc concentration categories were defined as deficiency (<60 μg/dL), marginal deficiency (≥60 to <80 μg/dL), and normal (≥80 μg/dL). Serum zinc concentrations were compared between the first age category (<40 years) and other age categories with Dunnett's method. Trends in P-values were estimated using the Jonckheere-Terpstra test for continuous variables.

RESULTS

The proportions of subjects with deficiency and marginal deficiency were 0.4% and 46.0% in men, and 0.6% and 38.4% in women, respectively. The deficiency/marginal deficiency group had significantly lower lipid profiles and nutritional status, and a significantly lower proportion were non-daily drinkers in both genders. Older age was significantly associated with lower serum zinc concentration only in men.

CONCLUSIONS

Our findings clarified a high proportion of serum zinc deficiency/marginal deficiency, especially in men, and suggest a possible association between serum zinc levels and nutritional status and alcohol consumption. It may be necessary to manage nutritional status, including zinc intake.

Relationship Between Parental Lifestyle and Dietary Habits of Children: A Cross-Sectional Study

Background

Although parents seek the best for their children, nutrition education for parents has attracted little attention to improve their children’s dietary habits. To address this gap, this study aimed to examine the relationship between parental lifestyle factors and children’s dietary habits.

Methods

We used data from the questionnaire survey of the Super Shokuiku School Project conducted in January 2016. The participants consisted of 1,632 elementary school children who answered questions about their lifestyle, while their parents answered parental lifestyle questions, including Breslow’s seven health practice score (BHPS). Logistic regression analysis was performed to evaluate the strength of the relationship between parental lifestyle factors and parental dietary attitudes or children’s dietary habits.

Results

Compared with good maternal BHPS (scores of 6–7), poor maternal BHPS (scores of 0–3) was significantly associated with less parental interest in Shokuiku, less parental consideration of nutrient balance, and an increased rate of children eating breakfast alone (adjusted odds ratio [aOR] 2.95; 95% confidence interval [CI], 1.82–4.78, aOR 3.86; 95% CI, 2.50–5.96, and aOR 2.42; 95% CI, 1.34–4.35, respectively). There was no significant difference between parental BHPS and the following children’s dietary habits: frequency of eating breakfast, vegetable intake, and snacking. These habits of children were associated with their personal lifestyle factors.

Conclusion

Two types of dietary habits among children were associated with lifestyle factors of both parents and children. Nutrition education might be especially important for parents to improve their dietary attitude and children’s dietary habits. However, different nutrition education interventions would be needed to appropriately address each dietary habit.

Achievement of Target Serum Uric Acid Levels and Factors Associated with Therapeutic Failure among Japanese Men Treated for Hyperuricemia/Gout

Objective To assess the rate of successfully achieving treatment goals among Japanese men with hyperuricemia/gout and identify factors influencing the success rate. Methods This cross-sectional study, conducted from January to December 2012, examined the serum uric acid (SUA) levels and clinical characteristics of 2,103 men with hyperuricemia/gout selected from an initial population of 136,770 individuals who participated in a workplace health checkup. The success rates (defined as SUA ≤6.0 mg/dL) were calculated, and a multivariate analysis was used to identify factors associated with "therapeutic failure" to achieve target SUA levels. Results The rate of successfully achieving the target SUA level was 37.5%. The body mass index (BMI) was significantly associated with therapeutic failure [25.0≤ Category (C) 2<27.5, adjusted odds ratio (AOR) =1.35; 27.5≤C3<30.0, AOR=1.69; C4 ≥ 30.0, AOR=1.94; relative to C1<25.0]. A significant positive association was also observed between waist circumference (WC) and therapeutic failure (85≤C2<90, OR=1.29; 90≤C3<95, OR=1.41; 95≤C4, OR=2.28; relative to C1<85.0 cm). Those with higher BMI/WC measurements were significantly more likely to have higher SUA levels than those with lower such measurements. The ongoing intake of dyslipidemia medication was identified as a protective factor against therapeutic failure. Discussion Our findings suggest a possible association between obesity and therapeutic failure, underscoring the importance of maintaining lipid profiles as part of managing SUA levels. Better management of both obesity and dyslipidemia may prevent future cardiovascular disorders by ensuring healthier SUA levels.

Association between health literacy and metabolic syndrome or healthy lifestyle characteristics among community-dwelling Japanese people

BACKGROUND

Few studies have assessed the association between health literacy (HL) and healthy lifestyle characteristics among Japanese people, and reports on the association between HL and prevalence of metabolic syndrome are also scarce.

METHODS

The present cross-sectional study included 1817 (781 men and 1036 women) Japanese individuals who participated in a medical health checkup at Bange Kosei General Hospital and Takada Kosei Hospital in Fukushima, Japan, from April 2013-2014. Information regarding HL and healthy lifestyle characteristics listed in Breslow's seven health practices was collected by self-administered questionnaire.

RESULTS

In multivariate logistic analysis, higher HL (≥14) was positively associated with healthy lifestyle characteristics [odds ratio (OR) = 2.08, 95 % confidence interval (CI) = 1.33-3.23] and inversely associated with prevalence of metabolic syndrome (OR = 0.67, 95 % CI = 0.48-0.95) among men. Among HL items, the ability to make decisions based on health-related information was significantly associated with healthy lifestyle characteristics (OR = 2.04, 95 % CI = 1.34-3.10 for men, OR = 1.38, 95 % CI = 1.30-1.85 for women) and inversely associated with prevalence of metabolic syndrome (OR = 0.62, 95 % CI = 0.44-0.88 for men, OR = 0.68, 95 % CI = 0.49-0.95 for women) in both sexes.

CONCLUSIONS

We found positive associations between HL and healthy lifestyle characteristics and an inverse association with prevalence of metabolic syndrome among men. Our findings also suggest that men and women are likely to engage in health-promoting behaviors and make decisions based on health-related information. These findings highlight the importance of comprehensive assessments, including HL, for health promotion in the community.

Association Between Serum Uric Acid Levels/Hyperuricemia and Hypertension Among 85,286 Japanese Workers

This cross-sectional study from January 2012 to December 2012 aimed to examine the sex-specific association between serum uric acid (SUA) levels/hyperuricemia and hypertension among Japanese patients. SUA level, medical histories, and lifestyle-related items were collected from 85,286 of 136,770 participants. Among those with hyperuricemia, the median age was 46 years and 97% were men, which was significantly different than those without hyperurecemia (44 years and 56%, respectively; P<.01). Hyperuricemia was 1.79 times more likely in hypertensive men than normotensive men and almost six times more likely in hypertensive women (odds ratio=5.92 and adjusted odds ratio=1.33 for men and adjusted odds ratio=1.81 for women) after multivariate analysis. SUA quartiles positively correlated with systolic and diastolic blood pressures in both sexes. Hyperuricemia and SUA levels were significantly associated with hypertension in both sexes. These findings underscore the importance of maintaining normal SUA levels to manage and prevent hypertension. Better management of SUA as well as blood pressure may have potential in preventing future cardiovascular disorders.

Achievement of Target Blood Pressure Levels among Japanese Workers with Hypertension and Healthy Lifestyle Characteristics Associated with Therapeutic Failure

BACKGROUND

Few studies have examined Japanese with regard to the achievement rates for target blood pressure levels, or the relationship between these rates and healthy lifestyle characteristics in patients with hypertension as defined by the newly established hypertension management guidelines (JSH2014). The aim of this study was to elucidate achievement rates and examine healthy lifestyle characteristics associated with achievement status among Japanese.

METHODS

This cross-sectional study, conducted in January-December 2012, examined blood pressure control and healthy lifestyle characteristics in 8,001 Japanese workers with hypertension (mean age, 57.0 years; 78.8% were men) who participated in a workplace health checkup. Data were collected from workplace medical checkup records and participants' self-administered questionnaires. We divided into 5 groups [G1; young, middle-aged, and early-phase elderly patients (65-74 years old) without diabetes mellitus or chronic kidney disease (CKD) (<140/90 mmHg), G2; late-phase elderly patients (≥75 years old) without diabetes mellitus or CKD (<150/90 mmHg), G3; diabetic patients (<130/80 mmHg), G4; patients with CKD (<130/80 mmHg), and G5; patients with cerebrovascular and/or coronary artery diseases (<140/90 mmHg)] according to JSH2014. And then, achievement rates were calculated in each group. Multivariate analysis identified healthy lifestyle characteristics associated with "therapeutic failure" of target blood pressure.

RESULTS

Target blood pressures were achieved by 60.2% of young, middle-aged, and early-phase elderly patients (G1), 71.4% of late-phase elderly patients (G2), 30.5% of diabetic patients (G3), 33.4% of those with chronic kidney disease (G4), and 66.0% of those with cerebrovascular and/or coronary artery diseases (G5). A body mass index of 18.5-24.9 and non-daily alcohol consumption were protective factors, and adequate sleep was found to contribute to therapeutic success.

DISCUSSION

We found low achievement rates for treatment goals among patients with chronic kidney disease and diabetes mellitus. Maintaining an ideal body weight and adequate alcohol consumption may help with blood pressure control. Lifestyle modification may be necessary for better management of hypertension.

Association between lifestyle-related disorders and visceral fat mass in Japanese males: a hospital based cross-sectional study

OBJECTIVE

This study aimed to examine the association between lifestyle-related disorders and visceral fat mass, and to estimate an appropriate cutoff value for visceral fat mass that correlated with body mass index (BMI) and waist circumference (WC).

METHODS

This cross-sectional study was conducted between July 2012 and August 2013 at Bange Kosei General Hospital, in Fukushima, Japan. All study participants were adult males who had completed voluntary medical check-ups that included estimation of visceral fat mass by bioelectrical impedance analysis (BIA). Participants were without past histories of atherosclerotic complications or were not currently taking medications for lifestyle-related disorders. Multivariate analysis was performed to estimate the association between lifestyle-related disorders and quartiles of visceral fat mass.

RESULTS

Of 536 total respondents, 442 were included in the analysis. Mean participant age was 56 years, and mean values of BMI, WC, and visceral fat mass were 24.1 kg/m(2), 85.9 cm, and 2.1 kg, respectively. Visceral fat mass ≥1.8 kg was positively associated with an increased prevalence of dyslipidemia, elevated blood pressure, and impaired glucose tolerance. Cutoff values that correlated with visceral fat mass (≥1.8 kg) were 85.3 cm for WC and 23.25 kg/m(2) for BMI.

CONCLUSION

Visceral fat mass ≥1.8 kg was positively associated with lifestyle-related disorders and closely related to WC and BMI cutoff values used to diagnose obesity. BIA may be a useful method for assessing visceral fat mass, and these findings provide important evidence for the use of BIA in the early detection of central obesity for preventing lifestyle-related disorders.

Changes in blood-pressure control among patients with hypertension from 2008 through 2011: surveys of actual clinical practice

We performed cross-sectional surveys to investigate changes in clinical practices regarding blood-pressure control in patients with hypertension from 2008 through 2011. Questionnaires regarding the care of patients with hypertension were mailed to members of the Kanagawa Physicians Association in Kanagawa Prefecture, Japan. Data were obtained on 675 patients in 2008, 332 in 2009, and 1,076 in 2011. The mean systolic blood pressure (BP) was significantly lower in 2011 than in 2008 (132.2±11.9 mm Hg versus 134.6±10.6 mm Hg). The office-measured target BP, according to the 2009 guidelines of the Japanese Society of Hypertension for the management of patients with hypertension, was achieved in 53.9% of patients in 2008, 55.1% in 2009, and 57.1% in 2011. In nonelderly patients (younger than 65 years), the achievement rate was significantly greater in 2011 (41.2%) than in 2008 (23.6%). This analysis showed that the factor most significantly associated with a decrease in office-measured BP was treatment with a larger number and higher doses of antihypertensive agents. To investigate changes in clinical practices according to the guidelines, further follow-up surveys are necessary.

Association between control to target blood pressures and healthy lifestyle factors among Japanese hypertensive patients: longitudinal data analysis from Fukushima Research of Hypertension (FRESH)

OBJECTIVE

To determine success rates in controlling target blood pressures longitudinally by measuring several factors, including lifestyle characteristics associated with uncontrolled blood pressures for target treatment goals.

METHODS AND PATIENTS

This prospective observational cohort study (September 2008-September 2010) collected information on blood pressure control status and healthy lifestyle factors listed in Breslow's seven health practices through medical records and self-administered questionnaires from 884 of the 1264 Japanese hypertensive patients initially registered in the FRESH study. Multivariate analysis adjusted for associated factors was performed to estimate the association between lifestyle change and "uncontrolled blood pressures" at the final follow-up survey.

RESULTS

Median age and proportion of men were 73 years and 39.1%, respectively. All survey failure rates were 37.6% among non-elderly patients (<65 years of age) without diabetes mellitus or chronic kidney disease, and 35.0% among patients with these diseases or myocardial infarction. Maintaining a healthy lifestyle was a protective factor against uncontrolled blood pressures in multivariate analysis. Obesity and smoking status were associated with uncontrolled blood pressures, and exercise frequency was borderline significance. The number of participants with healthy responses for these factors remained relatively low during follow up.

CONCLUSION

Our study revealed low rates of controlled blood pressures, especially in non-elderly patients without diabetes mellitus or chronic kidney disease, and patients with these diseases or myocardial infarction. Our data indicate the need to maintain a healthy lifestyle, in particular, ideal body weight and adequate exercise frequency, for better hypertension management according to treatment guidelines.

Achievement of cardiometabolic goals in aware hypertensive patients in Spain: a nationwide population-based study

Despite the importance of achieving cardiometabolic goals beyond blood pressure, in the health of hypertensives, no comprehensive assessment of these characteristics has been performed in whole countries. We studied in 2008-2010 a total of 11 957 individuals representative of the Spanish population aged≥18 years. Information on cardiometabolic characteristics was collected at the participants' homes, through structured questionnaires, physical examination, and fasting blood samples. A total of 3983 individuals (33.3%) had hypertension (≥140/90 mm Hg or current antihypertensive drug treatment), 59.4% were aware of their condition, 78.8% treated among those aware, and 48.5% controlled among those aware and treated (22.7% of all hypertensives). Of the aware hypertensives, 13.8% had a body mass index<25 kg/m2, 38.6% consumed <2.4 g/d of sodium, 19.3% were diabetic with 61% attaining goal hemoglobin A1c<6.5%, whereas 42.3% had hypercholesterolemia, with 38.1% reaching goal low-density lipoprotein<115 mg/dL. Only 30.7% of overweight patients received a prescription of specific method for weight loss, 17.4% of daily smokers were offered a smoking cessation strategy, and 15.8% of older patients were given a flu shot. Aware and unaware hypertensives showed a similar frequency of some lifestyle, such as adequate physical activity. In conclusion, in a European country with a well-developed, free-access healthcare system, achievement of many cardiometabolic goals among hypertensives is poor. Moreover, a serious deficiency in hypertension awareness and in the effectiveness of some lifestyle interventions among aware hypertensives is present. Greater effort is needed in the management of coexisting risk factors and on lifestyle medical advice to improve the cardiometabolic health of hypertensives.

Usefulness of desirable lifestyle factors to attenuate the risk of heart failure among offspring whose parents had myocardial infarction before age 55 years

Heart failure (HF) is one of the leading causes of hospitalization and death in the United States and throughout Europe. Although a higher risk for HF with antecedent myocardial infarction (MI) has been reported in offspring whose parents had MIs before age 55 years, it is unclear whether adherence to healthful behaviors can mitigate that risk. The aim of the present study was therefore to prospectively examine if adherence to healthy weight, regular exercise, moderate alcohol consumption, and abstinence from smoking can attenuate such increased HF risk. Information on parental history of MI and lifestyle factors was collected using questionnaires. Subjects adhering to ≥3 healthy lifestyle factors were classified as having good versus poor lifestyle scores. Incident HF was assessed via yearly follow-up questionnaires and validated in a subsample. During an average follow up of 21.7 ± 6.5 years, 1,323 new HF cases (6.6%), of which 190 (14.4%) were preceded by MI, occurred. Compared to subjects with good lifestyle scores and no parental histories of premature MI, multivariate adjusted hazard ratios for incident HF with antecedent MI were 3.21 (95% confidence interval 1.74 to 5.91) for subjects with good lifestyle score and parental histories of premature MI, 1.52 (95% confidence interval 1.12 to 2.07) for those with poor lifestyle score and no parental histories of premature MI, and 4.60 (95% confidence interval 2.55 to 8.30) for those with poor lifestyle scores and parental histories of premature MI. In conclusion, our data suggest that even in subjects at higher risk for HF because of genetic predisposition, adherence to healthful lifestyle factors may attenuate such an elevated HF risk.
