  • Indeed, decades of research have produced unequivocal evidence that waist circumference provides both independent and additive information to BMI for morbidity and mortality prediction. Even a small weight loss between 5 and 10 percent of your current weight will help lower your risk of developing diseases associated with obesity.

  • Prevalence remained significant only among men with inclusion of physical activity. Our findings suggest that television watching is positively associated with prevalence of abdominal obesity and obesity among both men and women.

Scientists don't know for sure, but research is providing strong clues. Although guidelines for the management of obesity from several professional societies recognize the importance of measuring waist circumference, in the context of risk stratification for future cardiometabolic morbidity and mortality, these guidelines limit the recommendation to measure waist circumference to adults defined by BMI to have overweight or obesity.

Our finding of a persistent association among men between sedentary activity and measures of obesity after adjusting for various types of physical activity warrants further investigation. Vigorous activity was defined as activity that caused large heart rate or breathing increases, and moderate activity was defined as activity that caused small increases. The fat surrounding the liver and other abdominal organs, so-called visceral fat, is very metabolically active.

Introduction

Obesity was defined as BMI at or above After 16 years, women wajst had reported the highest waist sizes — 35 inches or higher —had nearly double the risk of dying from heart disease, compared to women who had reported the lowest waist sizes less than 28 inches. Our findings showed strengthening of the associations between television watching and measures of obesity waist circumference and BMI after adjusting for various types of physical activity, especially for men. How Abdominal Fat Increases Disease Risk More than 60 years ago, the French physician Jean Vague observed that people with larger waists had a higher risk of premature cardiovascular disease and death than people who had trimmer waists or carried more of their weight around their hips and thighs.

Garvey, W. Although BMI can be used for most men and women, it does have some limits: It may overestimate body fat in athletes and others who have circjmference muscular build. Kissebah, A. Novel biomarkers must at the very least have an independent statistical association with health risk, after accounting for established risk markers in the context of a multivariable epidemiological model. Diabetes 52— Moreover, VAT is an established marker of morbidity 5051 and mortality 24 Moreover, height is only marginally associated with waist circumference

That makes waist circumference the better choice waist circumference many settings. Search for:. Although most of our findings are in agreement with other studies, little research exists that explores differences between the sexes in the associations between various types of sedentary and physical activity behaviors and obesity measures, adjusting for underlying factors such as food intake, that are linked to these activity behaviors. Each of the other models included the base model adjusted for each type of physical activity ie, moderate, vigorous, transportation as an independent variable. Although many types of physical activity were associated with reduced risk of obesity and abdominal obesity as our hypothesis predicted, work-based physical activity was not.

Transportation was defined as circumfrrence or bicycling to get size 20 waist circumference obesity and from places. When considering public health implications, our models show that public health initiatives must focus on increasing recreational physical activity and decreasing television-based sedentary activity.

Thus, for a given waist circumference, a larger BMI might represent a phenotype with elevations in lower body subcutaneous adipose tissue.

Accordingly, the inclusion of waist circumference measurement in routine practice affords practitioners with an important opportunity to improve the care and health of patients. Moreover, within each BMI category, individuals with high waist circumference values are at increased risk of adverse health outcomes compared with those with normal waist circumference values When BMI and waist circumference are considered as continuous variables in the same risk prediction model, waist circumference remains a positive predictor of risk of death, but BMI is unrelated or negatively related to this risk.

These observations are promising and support, at least for white adults, the clinical utility of the BMI category-specific waist circumference thresholds given in Table 1. A large waist circumference is a red flag for excessive abdominal fat, which is associated with obesity-related conditions, such as type 2 diabetes, high cholesterol, high triglycerides, high blood pressure and coronary artery disease.

A limitation of our study is its cross-sectional design, which precludes a causal inference of our findings. We found no association among men between eating meals prepared away from home and obesity or abdominal obesity. The two most common ways to measure abdominal obesity are waist circumference and waist size compared to hip size, also known as the waist-to-hip ratio.

Our findings also show that consuming meals prepared away from home or frozen prepared meals was associated with risk of abdominal obesity and obesity among women only.
