A comparison of two methods of assessing waist girth in males and females : an honors [thesis] (HONRS 499)

Abstract

The purpose of this study is to determine if there is a significant variance between the results of two differing methods of determining waist girth measurements and how this variance impacts a subject's disease risk stratification. Past research has shown a correlation between the absolute waist girth measurement and an increased risk for cardiovascular and metabolic disease. The standard measurement used for determining waist girth uses the narrowest location between the xyphoid process (tip of the sternum) and the umbilicus (belly button). Recent guidelines published by the United Stated Department of Agriculture (USDA) have altered the procedures for locating the waist girth measurement. This measurement requires the professional to measure the subject at the level of the iliac crest (top most point of the ilium or hip bone). The waists of one hundred one subjects were assessed at the two sites described above. In addition, the height, weight, age and gender of each subject were recorded. Comparisons were made among the subjects by dividing them into categories according BMI classification, gender, and age. Two-tail t-tests were then performed in order to declare statistical significance and draw conclusions from the study results. The subjects were risk was also evaluated strictly based upon the waist girth measurement and discussion of the validity and accuracy of the determinations produced by each site followed. This study is up for presentation at the Midwest and/or national ACSM conferences in the fall of 2004.
