Objective: Waist circumference reference values can be vary amongsocieties. Therefore, the purposeof this study was to determine the waist circumference values of Turkish adultspeople for 19-75 year. Material and Method: A total of 25.866 (11484females and 14382 males) adult participants were recruited, grouped intocategories of waist circumference in accordance with the World HealthOrganizasion cutoffs. Waist circumferencewas measured with a tape measure according to the recommendations of the World Health Organization. Results:It was found that waist circumference values varied atcertain age ranges. Furthermore, there was a statistically significantrelationship between the age variable and waist circumference values for male (r=.441) and female (r=.444) adults. It was determinedthat 87.91% of the male adults participating were to have normalvalues and 12.08% of them were to have higher risks of obesity related to thediseases, and 65.86% of female participantswere to have normal values and 34.14% of them were to have had higher risk ofobesity related diseases.Conclusions:The use waist circumference for the prediction ofrisk factor clustering among adults has significant clinical utility. These analyses should be continued in future studies in orderto examine both health and reference values between societies.
