BACKGROUND Waist circumference (WC) has been well recognized as a surrogate marker of abdominal adiposity. In peritoneal dialysis (PD) patients, however, aspects related to this dialysis modality, such as abdominal distension, presence of catheter and frequent hernia, raise questions regarding the reliability of WC measurements. Herein, we investigated for the first time whether WC is a reliabl...

The aim of this study was to elucidate further the precise nature of the so-called "white coat" (WC) effect. We enrolled 88 hypertensive (46 men, 42 women) and 18 normotensive (4 men, 14 women) subjects in whom beat-to-beat blood pressure (BP) and heart rate (HR) were measured with a Finapres device at rest (R period) and during conventional BP measurement (WC period). The WC effect was defined...

Considering the main effect of obesity on chronic non-communicable diseases, this study was performed to assess the association between body mass index (BMI), waist-circumference (WC), cardio-metabolic risk factors and to corroborate whether either or both BMI and WC are independently associated with the risk factors in a sample of Iranian adults. This cross-sectional study was performed on dat...

OBJECTIVE Childhood and adolescent overweight, defined by body mass index (BMI) are associated with an increased risk of cardiovascular disease in later life. Abdominal adiposity may be more important in associations with cardiovascular diseases but waist circumference (WC) has been rarely studied in children. We studied associations between BMI and WC and blood pressure (BP) and cholesterol in...

BACKGROUND There is an ongoing debate about the applicability of current criteria for large waist circumference (WC) in older adults. OBJECTIVES Our aim was to explore cut-off values for large WC in adults aged 70 years and older, using previously used and new methods. DESIGN Prospective cohort study. PARTICIPANTS Data of 1049 participants of the Longitudinal Aging Study Amsterdam (LASA) ...

BACKGROUND The prevalence of obesity is increasing throughout the world.Obesity assessed by body mass index (BMI) has shown to be associated with gestational complications while the relationship using waist circumference (WC) is not clear yet. The present study was aimed to determine the relationship between WC and adverse pregnancy complications. METHODS In this prospective cohort study, 114...

The scope of this study was to evaluate the association between waist circumference (WC) and body mass index (BMI) of Brazilian women of childbearing age studied in the most recent National Demographic and Health Survey (NDHS), in 2006. This study is an excerpt of the NDHS, which is a home-based cross-sectional study. The nutritional status of women was assessed by WC and BMI, considering exces...

BACKGROUND We examined the relationship between changes in waist circumference (WC) and the incidence of nonalcoholic fatty liver disease (NAFLD). METHODS A cohort study of 37,130 men and women were followed-up annually or biennially. Differences in WC between baseline and subsequent measurements were categorized in quartiles: first (WC loss), second (no change in WC as the reference), third ...

BACKGROUND Tungsten carbide nanoparticles are being explored for their use in the manufacture of hard metals. To develop nanoparticles for broad applications, potential risks to human health and the environment should be evaluated and taken into consideration. OBJECTIVE We aimed to assess the toxicity of well-characterized tungsten carbide (WC) and cobalt-doped tungsten carbide (WC-Co) nanopa...
