The Sex Specific Waist Circumference Cut Off Points to Predict Overweight or Obesity

The waist circumference (WC) cut off levels of the Caucasian people may not represent the characteristics of different ethnic groups. The investigators aimed to determine sex specific WC cut off points to predict obesity, metabolic syndrome and increased cardiovascular risk in Turkish adults.

About this study

Waist circumference (WC) is an easy and reliable measure of visceral adipose tissue and a simple index of cardiovascular risk. The World Health Organization (WHO) reported sex specific WC cut off values for the Caucasian people, named as action levels 1 and 2, to define the overweight or obese people. These cut off values, originally established in a Dutch population, were later adopted by several medical organizations in order to define Metabolic Syndrome. However, these cut off levels may not necessarily represent the characteristics of the other populations. Therefore it is recommended that the sex specific WC cut off points should be established for different ethnic groups.

The investigators aimed to investigate whether the suggested sex specific WC cut off points for the Caucasian adults are appropriate for the Turkish adult population. The secondary aim of the study is to search for better WC cut off points to predict obesity, metabolic syndrome and increased cardiovascular risk in Turkish adult men and women.

Treatment and study plan

Primary outcomes

Waist circumference cut off levels

Time frame: About a year to collect all the demographic data

These cut off levels were determined by the receiver operating curve analyses. The sum of the highest sensitivity and specificity values of the WC levels to determine the overweight (Body mass index (BMI) > 25kg/m2) and obese (BMI>30kg/m2) adults were taken as the cut off points. The cut off points to determine the overweight, were also taken as the WC limits for the diagnosis of metabolic syndrome.
