Body condition scoring (BCS) provides a readily available technique that can be used by both veterinary professionals and owners to assess the body condition of cats, and diagnose overweight or underweight conditions. The objective of this study was to evaluate a five-point BCS system with half-point delineations using dual-energy x-ray absorptiometry (DXA). Four evaluators (a veterinarian, veterinary technician, trained scorer and untrained scorer) assessed 133 neutered adult cats. For all scorers, BCS score was more strongly correlated with percent body fat than with body weight. Percent body fat increased by approximately 7% within each step increase in BCS. The veterinarian had the strongest correlation coefficient between BCS and percent fat (r = 0.80). Mean body fat in cats classified as being in ideal body condition was 12 and 19%, for 3.0 and 3.5 BCS, respectively. Within BCS category, male cats were significantly heavier in body weight than females within the same assigned BCS category. However, DXA-measured percent body fat did not differ significantly between male and female cats within BCS category, as assigned by the veterinarian (P >0.13). Conversely, when assessed by others, mean percent body fat within BCS category was lower in males than females for cats classified as being overweight (BCS >4.0). The results of this study show that using a BCS system that has been validated within a range of normal weight to moderately overweight cats can help to differentiate between lean cats and cats that may not be excessively overweight, but that still carry a higher proportion of body fat.
体况评分（BCS）提供了一种易于使用的技术，兽医专业人员和猫主人都可以用它来评估猫的体况，并诊断超重或体重不足的情况。本研究的目的是使用双能X线吸收法（DXA）评估一种有半分划分的五点BCS系统。四名评估人员（一名兽医、一名兽医技术员、一名经过培训的评分员和一名未经培训的评分员）对133只绝育成年猫进行了评估。对于所有评分员来说，BCS评分与体脂百分比的相关性比与体重的相关性更强。在BCS每增加一个等级时，体脂百分比大约增加7%。兽医的BCS评分与脂肪百分比之间的相关系数最强（r = 0.80）。对于BCS评分为3.0和3.5的猫，被归类为理想体况的猫的平均体脂分别为12%和19%。在BCS类别中，在相同指定BCS类别的情况下，雄性猫的体重明显比雌性猫重。然而，根据兽医的分类，在BCS类别中，雄性和雌性猫的DXA测量的体脂百分比没有显著差异（P >0.13）。相反，当由其他人评估时，对于被归类为超重（BCS >4.0）的猫，在BCS类别中雄性猫的平均体脂百分比低于雌性猫。本研究结果表明，使用在正常体重到中度超重范围内经过验证的BCS系统，有助于区分瘦猫和可能并非过度超重但仍携带较高比例体脂的猫。
