BACKGROUND Within-person variability in measured values of a risk factor can bias its association with disease. We investigated the extent of regression dilution bias in calculated variables and its implications for comparing the aetiological associations of risk factors. METHODS Using a numerical illustration and repeats from 42,300 individuals (12 cohorts), we estimated regression dilution ...

BACKGROUND Higher waist circumference and lower hip circumference are both associated with increased cardiovascular disease (CVD) risk, despite being directly correlated. The real effects of visceral obesity may therefore be underestimated when hip circumference is not fully taken into account. We hypothesized that adding waist and hip circumference to traditional risk factors would significant...

Aim: The main purpose of this study was to examine the accuracy of a specific pedometer (Silva model Pedometer Plus 56013-3) and accelerometer (Silva model Ex3 plus 56026) in women suffering from obesity. The second aim was to study the impact of BMI, waist and hip circumference and waist-hip ratio on different pedometer and accelerometer positions on the body. Methods: Forty women with a BMI >...

Objective: To evaluate the efficacy of anthropometric and body composition parameters in the prediction of body fat percentage and lipid profile in schoolchildren. Methods: Cross-sectional study with 209 schoolchildren aged between seven and nine years old. The following variables were evaluated: weight, height, body mass index, percentage of body fat, arm and waist circumferences, conicity ind...

OBJECTIVE To evaluate the usefulness of neck circumference as an index of excess weight and obesity in young adults while identifying its appropriate cutoff points. METHODS The study comprised 41 male and 109 female students, aged 18-20 years. Anthropometric markers of obesity were measured, including body mass index, waist circumference, hip circumference, waist-to-hip ratio, and compared wi...

BACKGROUND Estimates of excess mortality associated with body mass index (BMI; in kg/m(2)) have been calculated for the US population. OBJECTIVE The objective of this article is to compare the excess mortality associated with BMI levels to the excess mortality associated with other anthropometric variables. DESIGN For the 1988-1994 Third National Health and Nutrition Examination Survey, est...

BACKGROUND Epidemiological studies find a progressive increase in the prevalence of elevated blood pressure with increasing adipose tissue. But there is no common opinion about which effectiveness of the anthropometric measurement tools indicating general or android obesity are most important to follow up in patients with elevated blood pressures. OBJECTIVES To identify which anthropometric m...

BACKGROUND Indices predictive of adolescent central obesity include waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR). Such reference data are lacking for Greek adolescents. The aim of this study was to develop age- and gender-specific WC, WHR and WHtR smoothed reference percentiles for abdominal obesity among Greek adolescents aged 12-17 years, to investigate ...

AIM This study was conducted to investigate the correlation between waist/hip ratio (WHR) as a measurement of obesity and severity of coronary artery disease (CAD) assessed by angiography in Kosovo. METHODS The study included 82 patients with suspected or known CAD who were referred for coronary angiography. All patients were subjected to full individual medical history, clinical examination ...
