Waist-to-hip ratio, also known as waist-hip ratio, is the circumference of the waist divided by the circumference of the hips. It is more likely that a complex set of biological and neuroendocrine pathways related to cortisol secretion contribute to central adiposity, such as leptinneuropeptide ycorticotropin releasing factor and the sympathetic nervous system.

How to Calculate Waist to Hip Ratio -- What are the Risks of More Belly Fat

Waist circumference and waist-hip ratio guidelines -

Using data pooled from 15 prospective studies that included individuals, we demonstrated that the risk of incident CVD increases in men and women with elevations in WC or WHR.

In an effort to understand the causal pathway that relates abdominal obesity to CVD risk, we examined adjusted risk estimates. We tried to determine whether adjustment for confounders such as smoking i. moderately adjusted data would strengthen the association of abdominal obesity with CVD, and whether adjustment for factors in the causal pathway between abdominal obesity and CVD, such as blood lipids i.

maximally adjusted data , would attenuate the association. However, no changes in associations were identified. This supports prior investigations which demonstrate that abdominal obesity is an independent risk factor for CVD over and above other abdominal obesity correlates.

To explore whether CVD risk differed between men and women, we stratified our analyses by sex. We found a sex difference in the moderately adjusted subgroup analysis of beta-coefficients, in the maximally adjusted subgroup analysis of beta coefficients for WC, and within all adjustment subgroup analyses of extreme quantiles.

However, these differences were not statistically significant. We expected that a sex-related difference might exist because metabolic risk factors appear in women at lower WC and WHR thresholds than in men.

WHR has been suggested to be a superior predictor of CVD risk because it includes a measurement of hip circumference, which is inversely associated with dysglycaemia, dyslipidaemia, diabetes, hypertension, CVD, and death.

Increased hip circumference is associated with increased hip subcutaneous fat, gluteal muscle, and total leg muscle mass. However, these associations were not significantly different.

Although there may be advantages of the WHR over the WC, WHR is more difficult to perform and a less reliable measure than WC. A non-obese and an obese individual could theoretically have the same WHR, which could remain constant during weight change.

We were unable to examine the association of abdominal obesity with CVD risk by ethnic group. Most participants were white Caucasians, and only one article studied an exclusively non-white population. Our study has several strengths.

The first is clearly the number of participants assessed by the included articles. Over participants were followed for nearly 6 years, and there were over CVD events. Secondly, we included only prospective studies in order to minimize potential biases associated with retrospective study designs.

Thirdly, we included studies of healthy individuals who later suffered their first CVD episode in order to make our findings generalizable to healthy populations. Finally, we tried to utilize all available data in the literature and employed a novel technique to include the reference category in WLS meta-regression.

Our study has some limitations. The first is that we did not include studies that used a WC or WHR cut-point to denote abdominal obesity. Secondly, we could not evaluate the standardized linear associations of WC and WHR with CVD because standard deviations of each measure were not consistently reported in all articles.

However, we attempted to address this problem by pooling risk estimates representing the comparison of extreme quantiles for each measure.

Thirdly, studies were adjusted for different covariates, which contributed to heterogeneity among the moderate and maximally adjusted subgroups.

Finally, the small number of studies and significant heterogeneity limited our ability to detect small differences in risk.

Abdominal obesity as measured by WC and WHR is significantly associated with the risk of incident CVD events. These simple measures of abdominal obesity should be incorporated in CVD risk assessments. This study complies with the Declaration of Helsinki.

To find out their WHR, a person needs to measure both the circumference of their waist and their hips. Circumference means the distance around something. To measure the circumference of their waist, a person should stand up straight and breathe out, then measure their waist just above the belly button with a tape measure.
