Abstract Background Few prospective studies on association between waist circumference and hypertension have taken account of the dynamic change of WC, which caused by lifestyle modification. Methods After a baseline investigation, we conducted the first and the second follow-up assessments for subjects after 2 and 5years, respectively. The difference value (D-value, the value at the first follow-up minus the value at baseline) in WC was calculated to evaluate 2years change of WC. The association between 2years change of WC and incident hypertension was analyzed by using Cox proportional hazards regression model. Results Among 2778 participants free of hypertension at baseline and the first follow-up, 660 (23.8%) subjects developed hypertension over a period of 5years (between the first and the second follow-up assessments). In both genders, the incidence density and HRs of hypertension were all increased with WC D-value regardless of their abdominal obesity status at baseline. Compared with participants who were non-abdominal obese both at baseline and first follow up, hypertension risk was higher in subjects who were abdominal obese both at baseline and the first follow-up, and in subjects who were non-abdominal obese at baseline but with abdominal obesity at the first follow up. Conclusions WC dynamic change was associated with incident hypertension, and more WC reduction was associated with more hypertension risk decrease.
Summary Background Endothelial function predicts recurrence of adverse cardiac events in patients with acute coronary syndromes (ACS). Moreover, the recovery of endothelial function correlates with cardiac event-free survival. Objectives The aim of this study was to determine which clinical factors correlate with the improvement in endothelial function after ACS. Methods Vascular endothelial function was assessed in 98 patients with ACS by flow-mediated dilation (FMD) of the brachial artery usin...

Background and Aims. Currently, obesity has become a worldwide health problem affecting even children and yet little is known about its role as a determinant of high blood pressure in this age group. The aim of this epidemiological study was to determine the relationship between the increment of body mass index (BMI) and waist circumference (WC) on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in children and teenagers. Methods. The study was performed in Mexico City schools. ...
Abstract Objective We investigated the link between a reduction in waist circumference and metabolic syndrome. Methods 105 obese Japanese men were enrolled in this study with a 1-year follow-up. Anthropometric and body composition parameters, i.e. height, body weight, body fat percentage, waist circumference and hip circumference, blood pressure, triglyceride, HDL cholesterol and blood sugar, were evaluated. Metabolic syndrome was diagnosed using criteria developed in Japan. Results After a 1-ye...

Background: Coronary heart disease (CHD) risk factors increase with age and body mass index (BMI; in kg/m 2 ). However, whether lifestyle intervention ameliorates metabolic CHD risk factors in obese older adults is unknown. Objective: The objective was to determine whether lifestyle intervention improves metabolic CHD risk factors in obese older adults. Design: A 6-mo outpatient randomized controlled trial was conducted in obese (BMI ≥ 30) older (≥65 y) adults randomly assigned to diet and exerc...
Background: In Western populations, waist circumference (WC) is more predictive of cardiovascular disease (CVD) risk than is body mass index (BMI). It is unclear whether the same is true in Asian populations. Objective: The objective was to examine the independent effects of WC and BMI on CVD risk factors in China. Design: CVD risk factors, BMI, and WC were measured in a nationally representative cross-sectional study of 15 540 Chinese adults aged 35-74 y. Results: Higher WC tertiles were associ...

Objective: BMI (kilograms per meters squared) and waist circumference (WC) (measured in centimeters) are each associated with the risk of developing cardiovascular disease (CVD). Therefore, a combination of the two may be more effective in identifying subjects at risk than either alone. The present study sought to identify the combination of BMI and WC that has the strongest association with CVD risk factors in whites. Research Methods and Procedures: Subjects were 8712 white men and women from ...
Body mass index (BMI) and waist circumference are independently associated with blood pressure, but the dependence of these associations on gender and age has not been clarified. We investigated the associations of BMI and waist circumference with systolic (SBP) and diastolic (DBP) blood pressure and assessed possible interactions with gender and age. Data concerning blood pressure and anthropometric variables were collected at enrollment in a cohort study from 10,928 non-smoking adults, all ove...
Objective: NIH Clinical Guidelines (1998) recommend the measurement of waist circumference (WC, centimeters) within body mass index (BMI, kilograms per square meter) categories as a screening tool for increased health risk. Research Methods and Procedures: The Canada Heart Health Surveys (1986 through 1992) were used to describe the prevalence of the metabolic syndrome in Canada and to test the use of the NIH guidelines for predicting metabolic risk factors. The sample included 7981 participants...
