对哺乳动物身体状况的估计可以通过测量骨骼大小和体重来构建。我们使用来自澳大利亚两个野生家鼠种群（家鼠）的数据说明了这样做的方法，并指出了文献中常用的错误方法。个体家鼠的各项健康指标与胴体脂肪含量无相关性。家鼠的状态指数重复性相对较低，因为体重每天都在变化，而且不同观察者所测量的长度也不同。为了使活体动物的状态指数有用，必须消除观察者之间测量的偏差。
Estimates of body condition in mammals may be constructed from measures of skeletal size and body mass. We illustrate the methodology for doing this using data from two populations of feral house mice (Mus domesticus) in Australia, and point out an erroneous method that has commonly been used in the literature. Indices of condition for individual house mice were not correlated with the fat content of their carcasses. Indices of condition for house mice have a relatively low repeatability because of variation from day to day in body mass and because of variation in length measurements taken by different observers. Bias in measurements among observers must be eliminated to make indices of condition from live animals useful.
