The concern over the weight gain problem continues to grow among both the international scientific community and public health authorities, since overweight and obesity prevalence rates continue to increase worldwide. In Chile, two out of three people are overweight, whereas 25% of the adult population is obese. Abdominal fat, has been linked to the development of a number of metabolic disorders. Waist circumference (WC) and the waist:height ratio (WHtR) have recently been evidenced as good predictors of metabolic risk for both adults and children. Thus, the present work aims at establishing smoothed centile charts and LMS 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.
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 obese group the WC cutoff values were 99.75 cm and 92.35 cm for men and women, respectively. The cutoff point for WHtR was 0.59 for both obese men and women.
The study shows, for the first time, reference values for WC and WHtR for Chilean adults.
由于全球超重和肥胖患病率持续上升，国际科学界和公共卫生当局对体重增加问题的担忧不断加剧。在智利，三分之二的人超重，而25%的成年人口肥胖。腹部脂肪与多种代谢紊乱的发生有关。最近有证据表明，腰围（WC）和腰高比（WHtR）是成人和儿童代谢风险的良好预测指标。因此，本研究旨在基于全国健康调查（ENS）的数据，为智利成年人建立WC和WHtR的平滑百分位数图表和LMS表，以便获得识别高危人群的可靠信息。
纳入了4788名年龄在15 - 75岁（平均年龄46±18岁）的受试者样本。测量了体重、身高和WC，并计算了体重指数（BMI）和WHtR。使用L（曲线Box - Cox）、M（曲线中位数）、S（曲线变异系数）方法计算百分位数。在肥胖组中，男性和女性的WC临界值分别为99.75 cm和92.35 cm。肥胖男性和女性的WHtR临界值均为0.59。
该研究首次展示了智利成年人WC和WHtR的参考值。
