这项研究是为了确定寿命和品种大小之间的关联，在狗，根据数据来自宠物人口。77个美国养犬俱乐部品种进行了分析，收集了700多只狗的数据。以寿命为因变量，身高或体重为自变量进行多元线性回归分析。身高与寿命呈负相关（r =-0.603，p < 0.05），体重与寿命呈负相关（r =-0.679，p < 0.05）。体重是寿命的重要预测因子（p < 0.001），表明体重较小的品种通常比体重较重的品种寿命长。这些数据形成了利用狗作为模型进行衰老研究的基础工作，并为主人提供了预测狗品种寿命的定量方法，从而有助于宠物选择。(c)2006爱思唯尔有限公司保留所有权利。
This study was undertaken to determine the association between life spans and breed size in the dog, based upon data derived from the pet population. Seventy-seven American Kennel Club breeds were analyzed with data collected for more than 700 dogs. Multiple linear regression analysis was carried out with longevity as the dependent variable and height or weight as the independent variable. A negative correlation was observed between height and longevity (r = -0.603, p < 0.05), and between weight and longevity (r = -0.679, p < 0.05). Weight was the significant predictor of life span (p < 0.001), revealing that breeds smaller by weight generally live longer than heavier breeds. These data form the ground work for investigations of aging utilizing the dog as a model and provide owners with a quantitative method for predicting lifespan of dog breeds, thereby aiding in pet selection.
