Waist circumference and waist:height ratio percentiles using XXXX method in Chilean population.

@entity1 @entity11293 @entity28 @entity209
BACKGROUND AND AIMS: The concern over the weight gain problem continues to grow among both the international scientific community and public health authorities, since overweight and @entity28 prevalence rates continue to increase worldwide. In Chile, two out of three @entity1 are overweight, whereas 25% of the adult population is @entity28 . Abdominal fat, has been linked to the development of a number of @entity209 . Waist circumference (WC) and the waist:height ratio (WHtR) have recently been evidenced as good predictors of metabolic risk for both adults and @entity1 . Thus, the present work aims at establishing smoothed centile charts and @entity11293 tables for WC and WHtR for Chilean adults based on data from the National Health Survey-ENS, in order to have reliable information for identifying groups at risk. METHODS AND RESULTS: A sample of 4788 subjects aged 15-75 years old (mean age 46      18 years old) was considered. Body weight, height, and WC were measured and Body Mass Index (BMI) and WHtR were also determined. Percentiles were calculated using the L (curve Box-Cox), M (curve median), S (curve coefficient of variation) method. In the @entity28 group the WC cutoff values were 99.75  cm and 92.35  cm for @entity1 and @entity1 , respectively. The cutoff point for WHtR was 0.59 for both @entity28 @entity1 and @entity1 . CONCLUSION: The study shows, for the first time, reference values for WC and WHtR for Chilean adults.
