Direct assessment of skinfold thickness and waist and hip girths provides information about body fat and its distribution, avoiding estimation errors due to predictive equations. The present study aimed to provide new centile curves for the sum of eight skinfold thicknesses (Σ8SKF) and waist-to-hip ratio (WHR) in adult population, and to identify breakpoints during adulthood.
The present investigation was conceived as a multicenter, cross-sectional study. Stature, body mass, eight skinfold thicknesses (i.e., triceps, biceps, subscapular, iliac crest, supraspinal, abdominal, thigh, and calf) and waist and hip girths were measured according to the International Society for the Advancement of Kinanthropometry protocol in 1,313 men and 1,194 women aged 18-65 years. Smoothed age- and sex-specific percentile curves were generated using the Lambda Mu and Sigma method. For both sexes, simple linear regressions of the dependent variable (Σ8SKF and WHR) versus the explanatory variable (age) were performed to investigate changes in the response variable's slope and to test for potential breakpoints.
Reference percentile curves (3rd, 10th, 25th, 50th, 75th, 90th, and 97th) for Σ8SKF and WHR were provided. In men, Σ8SKF increased by 1.0 mm/year between the ages of 21 and 59, while in women, it increased by 3.8 mm/year between the ages of 38.5 and 47. In men, WHR showed a progressive increase of 0.004/year until the age of 28.4, followed by a slower increase of 0.003/year throughout the lifespan. In women, WHR increased by 0.003/year from the age of 20-65.
Σ8SKF and WHR appear sex- and age-specific. Scientists and practitioners are provided with reference values for the adult population.
直接测量皮褶厚度、腰围和臀围可提供有关体脂及其分布的信息，避免因预测方程导致的估计误差。本研究旨在为成年人群提供八部位皮褶厚度之和（Σ8SKF）及腰臀比（WHR）的新百分位数曲线，并确定成年期的转折点。
本研究为多中心横断面研究。按照国际人体测量学促进协会的方案，对1313名年龄在18至65岁的男性和1194名女性测量身高、体重、八部位皮褶厚度（即肱三头肌、肱二头肌、肩胛下、髂嵴、脊柱上、腹部、大腿和小腿）以及腰围和臀围。使用Lambda Mu和Sigma方法生成按年龄和性别划分的平滑百分位数曲线。对男女两性，均进行因变量（Σ8SKF和WHR）与解释变量（年龄）的简单线性回归，以研究响应变量斜率的变化并检验潜在的转折点。
提供了Σ8SKF和WHR的参考百分位数曲线（第3、10、25、50、75、90和97百分位数）。在男性中，Σ8SKF在21岁至59岁之间每年增加1.0毫米，而在女性中，在38.5岁至47岁之间每年增加3.8毫米。在男性中，WHR在28.4岁之前每年以0.004的速度逐渐增加，随后在整个生命周期中以每年0.003的较慢速度增加。在女性中，WHR从20岁至65岁每年增加0.003。
Σ8SKF和WHR呈现出性别和年龄特异性。为科学家和从业者提供了成年人群的参考值。
