Abstract
Western diet (WD), characterized by excess saturated fat and sugar intake, is a major contributor to obesity and metabolic and arterial dysfunction in humans. However, these phenotypes are not consistently observed in traditional inbred, genetically identical mice. Therefore, we sought to determine the effects of WD on visceral adiposity and metabolic/arterial function in UM-HET3 mice, an outbred, genetically diverse strain of mice. Male and female UM-HET3 mice underwent normal chow (NC) or WD for 12 weeks. Body mass and visceral adiposity were higher in WD compared to NC (P < 0.05). Female WD mice had greater visceral adiposity than male WD mice (P < 0.05). The results of glucose and insulin tolerance tests demonstrated that metabolic function was lower in WD compared to NC mice (P < 0.05). Metabolic dysfunction in WD as was driven by male mice, as metabolic function in female WD mice was unchanged (P > 0.05). Systolic blood pressure (BP) and aortic stiffness were increased in WD after 2 weeks compared to baseline and continued to increase through week 12 (P < 0.05). Systolic BP and aortic stiffness were higher from weeks 2-12 in WD compared to NC (P < 0.05). Aortic collagen content was higher in WD compared to NC (P < 0.05). Carotid artery endothelium-dependent dilation was lower in WD compared to NC (P < 0.05). These data suggest sex-related differences in visceral adiposity and metabolic dysfunction in response to WD. Despite this, arterial dysfunction was similar in male and female WD mice, indicating this model may provide unique translational insight into similar sex-related observations in humans that consume WD.

Combined effect of weight gain within normal weight range and parental hypertension on the prevalence of hypertension; from the J-MICC Study. J Hum Hypertens 2019; 34:125-131. [PMID: 31481698 DOI: 10.1038/s41371-019-0230-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 04/22/2019] [Accepted: 06/12/2019] [Indexed: 11/08/2022]
Abstract
The aim of this study is to show the combined effect of weight gain within normal weight range in adulthood and parental HT on the prevalence of HT. The study subjects were 44,998 individuals (19,039 men and 25,959 women) with normal weight (body mass index [BMI] 18.5-24.9) aged 35-69 years who participated in the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study. They were categorized into six groups by weight gain from age 20 years (<10 kg, and ≥10 kg) and by the number of parents having HT (no parent, one parent, and both parents). Odds ratios for HT were estimated after adjustment for age, sex, current BMI, estimated daily sodium intake, and other confounding factors. The prevalence of HT (31.5% in total subjects) gradually increased with greater weight gain from age 20 years and with greater number of parents with HT. Subjects who gained weight ≥10 kg and having both parents with HT showed the highest risk of having HT compared with those who gained weight <10 kg without parental HT (59.8% vs. 24.9%, odds ratio 4.25, 95% CI 3.53-5.13 after adjustment). This association was similarly observed in any category of age, sex, and BMI. Subjects who gained weight within normal range of BMI and having one or both parent(s) with HT showed the higher risk of having HT independent of their attained BMI in their middle ages. Thus, subjects having parent(s) with HT should avoid gaining their weight during adulthood, even within normal range of BMI, to reduce the risk of having HT.

Abstract
Background: Infection with Helicobacter pylori is the leading risk factor for noncardia gastric cancer, yet its influence on prognosis of gastric cancer is largely unknown. Thus, exploring the role of Helicobacter pylori (H. pylori) in survival could lead to a greater understanding of the high mortality associated with gastric cancer.Methods: Seropositivity to 15 H. pylori antigens was assessed using a multiplex assay in two prospective cohorts, the Shanghai Men's Health Study and the Shanghai Women's Health Study. Multivariable-adjusted Cox proportional hazards regression was used to examine the association between prediagnostic H. pylori antigen levels and gastric cancer-specific survival.Results: Prediagnostic levels of H. pylori serum antibodies that were previously associated with gastric cancer incidence in this population were not associated with gastric cancer survival, whether assessed in a 6-antigen panel [HR = 1.29; 95% confidence interval (CI), 0.78-2.13 for men; HR = 0.93; 95% CI, 0.57-1.52 for women], focused on CagA+H. pylori (HR = 0.73; 95% CI, 0.44-1.20 forwomen; HR = 1.27; 95% CI, 0.70-2.31 for men) or on the high-risk biomarkers of dual Omp and HP 0305 seropositivity (HR = 0.97; 95% CI, 0.72-1.30 for women; HR = 1.37; 95% CI, 0.97-1.94 for men).Conclusions: Prediagnostic H. pylori antigen levels are not associated with gastric cancer survival in East Asian populations.Impact: Identification of additional factors associated with gastric cancer survival would further our understanding of the high mortality associated with this malignancy.

Neuromuscular electrical stimulation acutely mobilizes endothelial progenitor cells in critically ill patients with sepsis. Ann Intensive Care 2016; 6:21. [PMID: 26969168 PMCID: PMC4788669 DOI: 10.1186/s13613-016-0123-y] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2015] [Accepted: 02/29/2016] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Endothelial progenitor cells (EPCs) have been suggested to constitute a restoration index of the disturbed endothelium in ICU patients. Neuromuscular electric stimulation (NMES) is increasingly employed in ICU to prevent comorbidities such as ICU-acquired weakness, which is related to endothelial dysfunction. The role of NMES to mobilize EPCs has not been investigated yet. The purpose of this study was to explore the NMES-induced effects on mobilization of EPCs in septic ICU patients. METHODS Thirty-two septic mechanically ventilated patients (mean ± SD, age 58 ± 14 years) were randomized to one of the two 30-min NMES protocols of different characteristics: a high-frequency (75 Hz, 6 s on-21 s off) or a medium-frequency (45 Hz, 5 s on-12 s off) protocol both applied at maximally tolerated intensity. Blood was sampled before and immediately after the NMES sessions. Different EPCs subpopulations were quantified by cytometry markers CD34(+)/CD133(+)/CD45(-), CD34(+)/CD133(+)/CD45(-)/VEGFR2 (+) and CD34(+)/CD45(-)/VEGFR2 (+). RESULTS Overall, CD34(+)/CD133(+)/CD45(-) EPCs increased from 13.5 ± 10.2 to 20.8 ± 16.9 and CD34(+)/CD133(+)/CD45(-)/VEGFR2 (+) EPCs from 3.8 ± 5.2 to 6.4 ± 8.5 cells/10(6) enucleated cells (mean ± SD, p < 0.05). CD34(+)/CD45(-)/VEGFR2 (+) EPCs also increased from 16.5 ± 14.5 to 23.8 ± 19.2 cells/10(6) enucleated cells (mean ± SD, p < 0.05). EPCs mobilization was not affected by NMES protocol and sepsis severity (p > 0.05), while it was related to corticosteroids administration (p < 0.05). CONCLUSIONS NMES acutely mobilized endothelial progenitor cells, measures of the endothelial restoration potential, in septic ICU patients.

Abstract
OBJECTIVES To evaluate if pre-pregnancy body mass index (BMI) determines blood pressure throughout pregnancy and to explore the role of gestational weight gain in this association. In addition, the effects of pre-pregnancy BMI and gestational weight gain on the occurrence of gestational hypertension and pre-eclampsia were investigated. DESIGN Prospective cohort study. SETTING Maternal and child health primary care referral centre, Jakarta, Indonesia. POPULATION AND MEASUREMENTS 2252 pregnant women visiting Budi Kemuliaan Hospital and its branch for regular antenatal care visits from July 2012 to April 2015. Pre-pregnancy BMI (kg/m(2)) was based on self-reported pre-pregnancy weight and measured height at first visit. Gestational weight gain was calculated as weight at the day of delivery minus the pre-pregnancy weight. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured during pregnancy at every visit. Linear mixed models were used to analyse this relation with repeated blood pressure measures as the outcome and pre-pregnancy BMI as the predictor. When looking at gestational hypertension and pre-eclampsia as outcomes, (multiple) logistic regression was used in the analysis. RESULTS Independent of pre-pregnancy BMI, SBP and DBP increased by 0.99 mm Hg/month and 0.46 mm Hg/month, respectively. Higher pre-pregnancy BMI was associated with higher pregnancy SBP (0.25 mm Hg/kg/m(2); 95% CI 0.17 to 0.34; p<0.01) and DBP (0.18 mm Hg/kg/m(2); 0.13 to 0.24; p<0.01) in adjusted analysis. Every 1 kg/m(2) higher pre-pregnancy BMI was associated with 6% and 9% higher odds for gestational hypertension (adjusted OR (aOR) 1.06; 95% CI 1.03 to 1.09; p<0.01) and pre-eclampsia (aOR 1.09; 1.04 to 1.14; p<0.01). Accounting for gestational weight gain did not attenuate these associations. CONCLUSIONS Pre-pregnancy BMI determines the level, but not the change, of blood pressure in pregnancy and is linked to higher odds for gestational hypertension and pre-eclampsia, independent of gestational weight gain.

Abstract
AIM Body weight gain adds risk for metabolic disorders and there are different metabolic changes in earlier and later adulthood. However, its impact on non-alcoholic fatty liver disease (NAFLD) was indeterminate. The aim of current study was to evaluate the impact of body weight gain on NAFLD and metabolic syndrome (MetS) during overall, earlier (25-40y) and later (over 40y) adulthood. METHODS 1119 subjects were selected to calculate changes in body weight (ΔBW), body mass index (BMI) (ΔBMI) and bodyweight per year (ΔBW/y) to analysis their impact on NAFLD and MetS in multi-variable regression models, and explored the potential mediators that associated ΔBMI with NAFLD by mediation analysis. RESULTS ΔBMI, ΔBW and ΔBW/y in whole adulthood were all positively associated with NAFLD and MetS. Body weight gain during earlier adulthood was more strongly associated with NAFLD than those during later adulthood. In NAFLD, the ORs of ΔBMI (third trisection), ΔBW and ΔBW/y were 3.86 (2.25, 6.57), 1.05 (1.02, 1.09) and 2.05 (1.29, 3.24) during earlier adulthood, and 1.47 (1.09, 2.02), 1.02 (1.00, 1.06), and 1.04 (.99, 1.13) over 40y. Insulin and HOMA-IR were important intermediates that associated ΔBMI with NAFLD. ΔBMI in earlier adulthood increased higher insulin and insulin resistance (IR) than later adulthood. CONCLUSIONS Body weight gain in adulthood was positively associated with NAFLD and MetS, and the association was stronger in earlier than later adulthood. Insulin and IR were important mediators that contributed to the association.

Abstract
BACKGROUNDS The number and activity of circulating endothelial progenitor cells (EPCs) in prehypertension is preserved in premenopausal women. However, whether this favorable effect still exists in prehypertensive premenopausal women with diabetes is not clear. METHODS This study compared the number and functional activity of circulating EPCs in normotensive or prehypertensive premenopausal women without diabetes mellitus and normotensive or prehypertensive premenopausal women with diabetes mellitus, evaluated the vascular endothelial function in each groups, and investigated the possible underlying mechanism. RESULTS We found that compared with normotensive premenopausal women, the number and function of circulating EPCs, as well as endothelial function evaluated by flow-mediated dilatation (FMD) in prehypertensive premenopausal women were preserved. In parallel, the Tie2/Akt/eNOS signaling pathway and the plasma NO level or NO secretion of circulating EPCs in prehypertensive premenopausal women was also retained. However, in presence of normotension or prehypertension with diabetes mellitus, the number or function of circulating EPCs and FMD in premenopausal women decreased. Similarly, the phosphorylation of Tie2/Akt/eNOS signaling pathway and the plasma NO level or NO secretion of circulating EPCs was reduced in prehypertension premenopausal with diabetes mellitus. CONCLUSION The present findings firstly demonstrate that the unfavorable effects of diabetes mellitus on number and activity of circulating EPCs in prehypertension premenopausal women, which is at least partially related to the abnormal phosphorylation of Tie2/Akt/eNOS signaling pathway and subsequently reduced nitric oxide bioavailability. The Tie2/Akt/eNOS signaling pathway may be a potential target of vascular protection in prehypertensive premenopausal women with diabetes mellitus.

Abstract
Previous epidemiological studies of circulating folate concentration and colorectal cancer have reported inconsistent results. We evaluated associations of prediagnostic plasma folate concentration with colorectal cancer risk in a case-control study nested within the Shanghai Men's Health Study (2002-2010). Included herein are 288 cases who were diagnosed with incident colorectal cancer and 575 controls who were individually matched to cases on baseline characteristics. Folate concentrations in plasma were measured by microbiological assay. Multivariate conditional logistic regression was used to assess associations of plasma folate concentrations with colorectal cancer risk. Plasma folate was nonsignificantly but positively associated with colorectal cancer risk. Odds ratios (OR) and 95% confidence intervals (CI) were 1.38 (0.95-2.02) for the middle tertile of plasma folate concentrations and 1.33 (0.90-1.98) for the highest compared to the lowest tertile. The positive association reached statistical significance for the highest tertile of folate concentrations for men with late-stage colorectal cancer (OR = 2.66; 95% CI = 1.03-6.86) and for the middle tertile for cases diagnosed within the first 4 years after blood collection (OR = 1.72; 95% CI = 1.02-2.92) and for men in the high BMI group (OR = 1.88; 95% CI = 1.14-3.11). In our study population, where folic acid fortification of the food supply and vitamin supplement use are uncommon, plasma folate concentration was positively associated with colorectal cancer risk among men who may have had preneoplastic lesions. These findings need to be confirmed in studies with specific assessment of preneoplastic lesions and repeated measurements of folate level over time.

Abstract
BACKGROUND AND AIM Prehypertension is an increasingly highly prevalent condition in the general population, and is associated with an increased risk for coronary heart disease and stroke. However, evidence from population-based studies of the risk factors for prehypertension is scant. We sought to examine the predictors of progression from normotension to prehypertension in a community-based population from Western New York. METHODS AND RESULTS A longitudinal analysis, over 6 years of follow-up, among 569 men and women (mean age 51.8 years) who were free of prehypertension, hypertension, cardiovascular disease and diabetes at the baseline examination, in the Western New York Health Study (WNYHS). Incident prehypertension at follow-up was defined as systolic blood pressure of 120-139 mm Hg and/or diastolic blood pressure of 80-89 mm Hg. The cumulative six year incidence of prehypertension was 33.5% (189/564). In bivariate analyses, there were several correlates of incident prehypertension, including age, BMI and waist circumference, impaired fasting glucose (IFG), uric acid, and baseline blood pressure levels. After multivariate adjustment, IFG at baseline [odds ratio (OR): 1.70, 95% CI: 1.07-2.69) and weight gain since age 25 (OR: 1.12, 1.04-1.21 per 10 lb increase)] were the strongest significant predictors of prehypertension at follow-up. Neither baseline waist circumference nor change in BMI were predictor variables in models when they were substituted for weight gain. CONCLUSIONS Results from this study suggest early dysregulation of glucose metabolism and weight gain over the lifespan may represent important risk factors for prehypertension in the general population.

Abstract
OBJECTIVE To evaluate the association between body mass index and mortality from overall cardiovascular disease and specific subtypes of cardiovascular disease in east and south Asians. DESIGN Pooled analyses of 20 prospective cohorts in Asia, including data from 835,082 east Asians and 289,815 south Asians. Cohorts were identified through a systematic search of the literature in early 2008, followed by a survey that was sent to each cohort to assess data availability. SETTING General populations in east Asia (China, Taiwan, Singapore, Japan, and Korea) and south Asia (India and Bangladesh). PARTICIPANTS 1,124,897 men and women (mean age 53.4 years at baseline). MAIN OUTCOME MEASURES Risk of death from overall cardiovascular disease, coronary heart disease, stroke, and (in east Asians only) stroke subtypes. RESULTS 49,184 cardiovascular deaths (40,791 in east Asians and 8393 in south Asians) were identified during a mean follow-up of 9.7 years. East Asians with a body mass index of 25 or above had a raised risk of death from overall cardiovascular disease, compared with the reference range of body mass index (values 22.5-24.9; hazard ratio 1.09 (95% confidence interval 1.03 to 1.15), 1.27 (1.20 to 1.35), 1.59 (1.43 to 1.76), 1.74 (1.47 to 2.06), and 1.97 (1.44 to 2.71) for body mass index ranges 25.0-27.4, 27.5-29.9, 30.0-32.4, 32.5-34.9, and 35.0-50.0, respectively). This association was similar for risk of death from coronary heart disease and ischaemic stroke; for haemorrhagic stroke, the risk of death was higher at body mass index values of 27.5 and above. Elevated risk of death from cardiovascular disease was also observed at lower categories of body mass index (hazard ratio 1.19 (95% confidence interval 1.02 to 1.39) and 2.16 (1.37 to 3.40) for body mass index ranges 15.0-17.4 and <15.0, respectively), compared with the reference range. In south Asians, the association between body mass index and mortality from cardiovascular disease was less pronounced than that in east Asians. South Asians had an increased risk of death observed for coronary heart disease only in individuals with a body mass index greater than 35 (hazard ratio 1.90, 95% confidence interval 1.15 to 3.12). CONCLUSIONS Body mass index shows a U shaped association with death from overall cardiovascular disease among east Asians: increased risk of death from cardiovascular disease is observed at lower and higher ranges of body mass index. A high body mass index is a risk factor for mortality from overall cardiovascular disease and for specific diseases, including coronary heart disease, ischaemic stroke, and haemorrhagic stroke in east Asians. Higher body mass index is a weak risk factor for mortality from cardiovascular disease in south Asians.

Abstract
Most epidemiological studies evaluating the association of fruit and vegetable intakes on lung cancer risk were conducted in North American and European countries. We investigated the association of intakes of fruits, vegetables, dietary vitamins A and C, and folate with lung cancer risk among 61,491 adult Chinese men who were recruited into the Shanghai Men's Health Study, a population-based, prospective cohort study. Baseline dietary intake was assessed through a validated food frequency questionnaire during in-home visits. Multivariate Cox regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of lung cancer risk associated with dietary intakes. During a median follow-up of 5.5 yr, 359 incident lung cancer cases accrued after the first year of follow-up and 68.8% of them were current smokers. Intakes of green leafy vegetables, β-carotene-rich vegetables, watermelon, vitamin A, and carotenoids were inversely associated with lung cancer risk; the corresponding HR (95% CI) comparing the highest with the lowest quartiles were 0.72 (0.53-0.98), 0.69 (0.51-0.94), 0.65 (0.47-0.90), 0.63 (0.44-0.88), and 0.64 (0.46-0.88). Intake of all fruits and vegetables combined was marginally associated with lower risk. Our study suggests that the consumption of carotenoid-rich vegetables is inversely associated with lung cancer risk.

Abstract
Actual cardiovascular disease (CVD) risk and related factors among blue collar workers employed by small businesses were investigated. This cross-sectional study of 238 Korean blue collar workers used surveys, anthropometric and blood pressure measurements, and blood sampling for lipid and glucose levels to answer the research questions. Multiple regression techniques were used to analyze study data. The prevalence of actual CVD risk among blue collar workers was 32 cases per 100 workers. A multiple regression model showed that a combination of individual, psychosocial, and work-related factors explained 34% of the variance in actual CVD risk. The significant predictors of actual CVD risk included knowledge of CVD risk, risk perception, job stress, and waist-to-hip ratio. It is important for clinicians to consider all of these significant predictors of actual CVD risk when designing an intervention program to reduce CVD among Korean blue collar workers.

Abstract
OBJECTIVE The aim of this study was to examine the association between BMI and risk of incident hypertension among Japanese men and women who are middle-aged and older. DESIGN Prospective, population-based cohort study. PATIENTS A total of 68 205 nonhypertensive adults (18 336 men and 49 869 women) aged 40-79 years who completed health check-ups in the Ibaraki prefecture, Japan, in 1993 were followed up through 2006. To exclude the impact of BMI change during the follow-up period, a time-dependent covariate Cox proportional hazards model was used to compute the hazard ratios of incident hypertension according to BMI categories. Incident hypertension was defined as a SBP of at least 140 mmHg, a diastolic BP of at least 90 mmHg, and/or hypertensive medication use. RESULTS A total of 30 982 adults (45.4%) developed hypertension (9331 men and 21 651 women) during a mean of 3.9 years of follow-up. Compared with a BMI of less than 19.0, time-dependent covariates adjusted hazard ratios [95% confidence interval (CI)] for hypertension among participants with a BMI of at least 25.0 were 1.42 (1.17-1.73) for men aged 40-59 years, 1.34 (1.19-1.51) for men aged 60-79 years, 1.47 (1.33-1.62) for women aged 40-59 years, and 1.29 (1.18-1.41) for women aged 60-79 years. CONCLUSION The baseline BMI is associated with future risk for incident hypertension even after accounting for weight change during the follow-up period. Weight loss may be recommended to nonhypertensive obese adults to prevent the development of hypertension.

Abstract
BACKGROUND Treatment and care of elderly patients with diabetes and hypertension means a hard task in primary care. Patients with these two components of metabolic syndrome are often overweight or obese. Although some parameters of metabolic syndrome are usually measured in a medical setting, checking body weight is usually done by the patients. AIM The aim of this study is to analyse the patients' self-recorded data on weight and compare them according to hypertension and diabetes. PATIENTS AND METHODS Five hundred and forty people (225 men and 315 women) between 60 and 75 years of age were eventually selected in primary care settings. Retrospective self-recorded data on recent weights and every decade since the age of 20, as well as the decade prior to diagnosis were collected. The data of patients with and without diabetes and/or hypertension were compared. RESULTS The current mean body weight was significantly higher in all groups than at the age of 20. Compared with the control group, hypertensive men and women were approximately of the same weight in their twenties and, also, recently, but they gained more weight in the 4th and 5th decades of their life. Diabetics started at higher weights. The greatest weight gain was observed as follows: between 20-30 years and 30-40 years in men and women, respectively, as well as between 50-60 years of age and in the last decade prior to diagnosis in both genders. Weight gain in the control group was steady at a lower rate. CONCLUSIONS Weight gain between 20-40 years of age could be an important factor in the aetiology of diabetes. Stable or at least limited weight gain may be a preventive factor. Considering the limitations of the study, further and decades long epidemiological evaluations are suggested in a larger study population.

Abstract
Endothelial progenitor cells (EPCs) are thought to participate in endothelial cell regeneration and neovascularization in either a direct or an indirect way. The number of circulating EPCs is influenced by many factors like disease status, medication, age, and fitness level and is an independent predictor of disease progression and cardiovascular events. Experimental as well as clinical studies during the last 10 years clearly demonstrated that physical exercise training has a beneficial effect on endothelial function, which is a clear predictive value for cardiovascular mortality. Over the last years mainly clinical studies provided solid evidence for an exercise training induced mobilization of EPCs from the bone marrow, thereby possibly influencing the regeneration of the endothelial cell layer. This review will discuss the mechanisms how exercise induces mobilization of EPCs from the bone marrow with a focus on the influence on the redox balance.

Abstract
OBJECTIVE To assess the relationship between patterns of overweight during adulthood and systolic (SBP) and diastolic (DBP) blood pressure (BP) at age 53. METHOD Data are from 3035 male and female participants of the 1946 British birth cohort study. Body mass index (BMI) was obtained at ages 20, 26, 36, 43 and 53 years. Censored regression models accounting for medication were used to investigate associations of BP at 53 years with overweight (BMI > 25 kg/m) at each age, age at first overweight and conditional weight gain. Sex interactions were also examined. RESULTS Overweight at all ages except for 20 years in men was positively associated with BP at 53 years. After adjusting for current BMI, only overweight at age 43 contained additional information on BP in men. Men who were overweight at age 26 had a SBP 8.7 mmHg higher [95% confidence interval (CI) 4.4-13.0] than those first overweight at 53 years. Similar patterns but smaller associations were seen in women [P(interaction) < 0.001). All periods of adult weight gain (26-36, 36-43, 43-53 years) were associated with a higher BP. BMI tracked strongly through adulthood, the BMI at 53 years in men first overweight at 26 was 30.9 kg/m (95% CI 30.5-31.4) compared to 26.4 (95% CI 26.3-26.6) in those first overweight at age 53. CONCLUSIONS Early adult overweight and all periods of adult weight gain irrespective of earlier BMI were associated with higher BPs. This highlights the importance for later health of preventing overweight in early adulthood.

Abstract
OBJECTIVES Although some prospective cohort studies have shown that baseline BMI is positively associated with a future incident risk for hypertension, these studies do not account for weight changes during the observation period. Therefore, it is not evident whether future incident risk for hypertension in obese, non-hypertensive people increases when their weight remains stable. We examined the association between long-term weight stability and risk for developing hypertension. METHODS A total of 5201 Japanese male workers aged 30-59 years underwent health checkups in 2002 and were followed through 2006. To consider transitions in covariates during the follow-up period, we used a time-dependent covariate Cox proportional hazard model to compute the relative risks (RRs) of incident hypertension. Furthermore, as a complementary analysis, we restricted the data to individuals whose BMI remained unchanged (± 5% of baseline BMI) during the follow-up and compared the RRs between BMI categories. RESULTS During the follow-up, there were 899 newly diagnosed cases of hypertension among the 5201 men (14,888 person-years). Mean change in BMI during the follow-up period of all subjects was 0.2 ± 1.1 kg/m(2) (range: -6.6 to 6.3 kg/m(2)). The multivariate RRs for hypertension increased as BMI increased when we applied the time-dependent covariate Cox proportional hazard model. The complementary analysis showed that the multivariate RR (confidence interval) within the ≥ 27.0 kg/m(2) BMI category was 1.43 (1.16-1.77) times higher than the reference of 23.0-24.9 kg/m(2), whereas the RR for the <21.0 kg/m(2) BMI category was 0.63 (0.51-0.79) times lower than the reference. CONCLUSIONS A higher baseline BMI increases future incident risk for hypertension even when there has been no major weight increase. Weight management should be encouraged for obese, non-hypertensive people to prevent future hypertension.

Abstract
Endothelial dysfunction is related to reduced arterial elasticity in patients with essential hypertension. Circulating endothelial progenitor cells (EPCs), an important endogenous repair approach for endothelial injury, is altered in hypertensive patients. However, the association between alteration in circulating EPCs and hypertension-related reduced arterial elasticity has not been reported. The purpose of this study is to investigate the association between alteration in circulating EPCs and hypertension-related reduced arterial elasticity. We measured the artery elasticity profiles including brachial-ankle PWV (baPWV) and C1 large and C2 small artery elasticity indices in patients with essential hypertension (n = 20) and age-matched normotensive subjects (n = 21). The number and activity of circulating EPCs isolated from peripheral blood were determined. Compared to normotensive subjects, the patients with hypertension exhibited decreased C1 large and C2 small artery elasticity indices, as well as increased baPWV. The number of circulating EPCs did not differ between the two groups. The migratory and proliferative activities of circulating EPCs in hypertensive patients were lower than those in normotensive subjects. Both proliferatory and migratory activities of circulating EPCs closely correlated with arterial elasticity profiles, including baPWV and C1 large and C2 small artery elasticity indices. Multivariate analysis identified both proliferative and migratory activities of circulating EPCs as independent predictors of the artery elasticity profiles. The present study demonstrates for the first time that impaired activity of circulating EPCs is associated with reduced arterial elasticity in patients with hypertension. The fall in endogenous repair capacity of vascular endothelium may be involved in the pathogenesis of hypertension-related vascular injury.

Abstract
Improved understanding of the determinants of blood pressure (BP) changes during pregnancy is essential for decreasing the morbidity and mortality borne by women and their families worldwide. While most epidemiological studies consider associations based on categorical risk factor classifications, using measurements on a continuous scale has been advocated as a means of gaining richer insights into biological processes. We modelled the relationship during pregnancy of continuous systolic (S) and diastolic (D) BP distributions with gestational age and pre-pregnancy body mass index (BMI) using fractional polynomials. We used information, including antenatal BP values abstracted from medical records, from a prospective cohort of 1733 women recruited before 20 weeks' gestation. The percentiles for SBP and DBP changed over pregnancy, with DBP percentiles decreasing initially, followed by an increase starting about mid-second trimester. Modelling the joint impact of BMI and gestational age on mean BP indicated an increase in mean BP with increasing BMI that was attenuated at higher BMI levels, later in pregnancy. This attenuation persisted in a variety of sub-analyses which explored the possibility that it was caused by confounding or by influential groupings of subjects. Estimated longitudinal percentiles that characterise the BP distribution across gestation may facilitate evaluation of BP during pregnancy. BP patterns observed over pregnancy and, in particular, the attenuation of BP increases at high BMI, late in pregnancy, can provide insights towards elucidating the mechanisms that drive BP changes during pregnancy.

Abstract
Changes in BMI and body size were compared to incident hypertension in 24,550 men and 10,111 women followed prospectively as part of the National Runners' Health Study to test whether long-term weight change affects hypertension risk. Incident hypertensions were reported by 2,143 men and 430 women during (mean +/- s.d.) 7.8 +/- 1.8 and 7.5 +/- 2.0 years of follow-up, respectively. Despite being active, men's and women's BMI increased 1.15 +/- 1.70 and 0.95 +/- 1.89 kg/m(2), respectively, and their waist circumferences increased 2.97 +/- 5.02 and 3.29 +/- 6.67 cm, respectively. Compared to those whose BMI declined, those who gained >or=2.4 kg/m(2) had an odds ratio (95% confidence interval) of 1.68 (1.45, 1.94) for becoming hypertensive if male and 1.42 (1.05, 1.92) if female. Men whose waist circumference increased >or=6 cm had an odds ratio of 1.22 (1.01, 1.47) for becoming hypertensive compared to those whose waists decreased. In both sexes, the odds for hypertension were significantly related to BMI at follow-up when adjusted for baseline BMI, but generally not to baseline BMI when adjusted for follow-up BMI. In the subset whose weights remained relatively unchanged during follow-up (+/-0.4 kg/m(2)), each kg/m(2) increment in BMI was associated with an odds ratio for becoming hypertensive of 1.19 (1.14, 1.24) in men and 1.11 (1.02, 1.20) in women. Thus, even among lean, physically active individuals: (i) weight gain increases hypertension risk; (ii) higher body weight increases the hypertension risk in a dose-dependent manner in the absence of any weight change; and (iii) there is no advantage carried forward to having been previously lean.

Abstract
BACKGROUND Insulin resistance and obesity are recognized as left ventricular (LV) mass determinants independent of blood pressure (BP). Prevalence of LV hypertrophy (LVH) and the relationship between LV mass to body composition and metabolic variables were evaluated in normotensive individuals as participants of a population-based study. METHODS LV mass was measured using the second harmonic image by M-mode 2D guided echocardiography in 326 normotensive subjects (mean 47+/-9.4 years). Fasting serum lipids and glucose, BP, body composition and waist circumference (WC) were recorded during a clinic visit. RESULTS Applying a normalization criterion not related to body weight (g/height raised to the power 2.7) and the cut-off points of 47.7 (men) and 46.6 g/m(2.7) (women), LVH was found in 7.9% of the sample. Univariate analysis showed LV mass (g/m(2.7)) related to age, body mass index (BMI), WC, fat and lean body mass, systolic and diastolic BP, and metabolic variables (cholesterol, HDL-c, triglycerides and glucose). In multivariate analysis only BMI and age-adjusted systolic BP remained as independent predictors of LV mass, explaining 31% and 5% of its variability. Removing BMI from the model, WC, age-adjusted systolic BP and lean mass remained independent predictors, explaining 25.0%, 4.0% and 1.5% of LV mass variability, respectively. After sex stratification, LV mass predictors were WC (8%) and systolic BP (5%) in men and WC (36%) and systolic BP (3%) in women. CONCLUSION BMI in general and particularly increased abdominal adiposity (WC as surrogate) seems to account for most of LV mass increase in normotensive individuals, mainly in women.

Abstract
BACKGROUND: Studies of the lifestyle predictors of cardiovascular diseases (CVD) have been predominantly conducted in Caucasian populations. There are few data from other populations, such as Chinese men, who have different lifestyles and a different spectrum of CVD as compared with Caucasian populations. METHODS: Based on the baseline data of the Shanghai Men's Health Study during March 2002-June 2006, a matched case-control analysis including 518 myocardial infarction, 333 hemorrhagic stroke, and 1927 ischemic stroke cases was conducted. Five controls were selected for each case. The lifestyle factors under study included alcohol, tea and ginseng consumption, physical activity during adolescence, and weight change from age 20 to 40. The associations of these lifestyle factors with myocardial infarction and stroke were evaluated. To account for the misclassification of exposures and disease diagnosis, a sensitivity analysis was conducted. RESULTS: Alcohol consumption was inversely associated with myocardial infarction (OR=0.63, 95% CI: 0.50, 0.80). Tea consumption was inversely associated with hemorrhagic (OR=0.63, 95% CI: 0.49, 0.81) and ischemic stroke (OR=0.77, 95% CI: 0.69, 0.85). Weight increase from age 20 to 40 was positively associated with myocardial infarction and stroke in a dose-response manner (trend p<0.001). CONCLUSIONS: Alcohol and tea consumption may decrease the prevalence of myocardial infarction and stroke, respectively. Weight increase from age 20 to 40 may increase the prevalence of myocardial infarction and stroke in Chinese men.

Abstract
BACKGROUND Individuals with prehypertension, a new blood pressure category defined as systolic blood pressure of 120-139 mm Hg and/or diastolic blood pressure of 80-89 mm Hg, are at an increased risk for heart diseases and are strongly recommended to practice lifestyle changes, including weight control. Data on impacts of long-term weight change on prehypertension are sparse. OBJECTIVE To evaluate the association between weight change since age 20 and prehypertension risk. METHODS In this cross-sectional analysis of 36 075 non-hypertensive women aged 40-70 years, information on weight history was collected at enrollment in the Shanghai Women's Health Study; blood pressures were measured 2-3 years later by medical professionals. The odds ratios (ORs) of prehypertension were calculated for women who gained or lost weight since age 20 compared with those with stable weight (gain or loss <5 kg), adjusting for age, lifestyle factors, sodium intake and body mass index at age 20. RESULTS A total of 47% of the study participants (n=16 981) had prehypertension. For a 6- to 10-kg gain, the OR (95% CI) was 1.36 (1.28-1.45); for 11- to 15-kg gain, 1.64 (1.54-1.75); for 16- to 20-kg gain, 2.32 (2.14-2.51); for 21- to 25-kg gain, 2.91 (2.60-3.26); and for a gain >25 kg; 3.65 (3.13-4.26). While for a 6- to 10-kg loss and a loss >10 kg, the respective ORs were 0.76 (0.67-0.87) and 0.47 (0.38-0.59). The increase in prehypertension risk associated with each 1-kg gain was similar to that associated with a 1-year increase in age. Although weight gain during early adulthood appeared to have a more pronounced effect on the risk of prehypertension, weight gain later in life also contributed significantly to an elevated risk. CONCLUSION Weight gain since age 20 substantially increases risk for prehypertension in non-hypertensive individuals, while weight loss significantly lowers the risk, emphasizing the importance of weight control throughout adulthood in preventing hypertension.
