Waist circumference (WC) measurement is a useful tool in the assessment of overweight/obese individuals, but standard measures may miss an apron of 'overhanging' fat (termed 'panniculus'). The objective of this study was to assess whether, in clinically overweight/obese youth, 'pannicular' WC better correlates with fat mass than a standard WC measurement.
Standard and pannicular WC, alongside body composition (BC) measures, were collected from 181 consultations on 127 overweight and obese children/adolescents (52% male; mean (standard deviation) age 12.5 (3.4) years). Correlation coefficients describe associations between WC and measures of BC, and between ΔWC and ΔBC, while linear regression models assessed which of the WC measures explained more of the variability in BC and ΔBC over time.
Standard and pannicular WC were highly correlated (r = 0.95). Correlation coefficients with measures of BC were generally greater for pannicular than standard WC, with greatest correlations seen for whole body (r = 0.94 vs. 0.85, respectively) and truncal (r = 0.86 vs. 0.77) fat mass. Furthermore, pannicular and Δpannicular WC explained more variability in truncal fat and Δtruncal fat than the standard measure of WC.
These data show that pannicular, rather than standard, WC measurements better correlate with absolute measures of fat mass, and their change over time, in clinically overweight/obese youth.
腰围测量是评估超重/肥胖个体的一项有用工具，但标准测量方法可能会遗漏“悬垂”脂肪（称为“腹垂肉”）。本研究的目的是评估在临床超重/肥胖的青少年中，“腹垂肉”腰围与脂肪量的相关性是否优于标准腰围测量。
收集了127名超重和肥胖儿童/青少年（52%为男性；平均（标准差）年龄12.5（3.4）岁）181次会诊时的标准腰围和腹垂肉腰围，以及身体成分测量数据。相关系数描述了腰围与身体成分测量之间的关联，以及腰围变化量（ΔWC）与身体成分变化量（ΔBC）之间的关联，而线性回归模型评估了哪种腰围测量方法能更好地解释身体成分及其随时间的变化量中更多的变异性。
标准腰围和腹垂肉腰围高度相关（r = 0.95）。腹垂肉腰围与身体成分测量的相关系数总体上大于标准腰围，全身脂肪量（分别为r = 0.94和0.85）和躯干脂肪量（r = 0.86和0.77）的相关性最高。此外，腹垂肉腰围及其变化量比标准腰围测量能更好地解释躯干脂肪量及其变化量中的更多变异性。
这些数据表明，在临床超重/肥胖的青少年中，腹垂肉腰围测量而非标准腰围测量与脂肪量的绝对测量值及其随时间的变化具有更好的相关性。
