Currently, five-point body condition scoring (BCS) is widely used by veterinarians and clinicians to assess adiposity in dogs in Japan. However, BCS score assignment is subjective in nature, and most clinicians do not score with half points, instead preferring to round off values, thereby rendering less accurate assessments. Therefore, we sought to determine whether assessing body fat percentage using simple morphometric measurements and supplementing this with five-point BCS can have increased sensitivity for detecting increasing adiposity in overweight small-medium sized dog breeds via plasma metabolite validation.
Overall, lean body fat percentage was determined to be 15%-22% for male (non-neutered/neutered) dogs and 15%-25% for female (nonspayed/spayed). Dogs categorized as overweight by BCS had significantly higher levels of nonesterified fatty acids ( = 0.005), whereas animals categorized as overweight by BCS + body fat percentage were observed to have significantly higher levels of nonesterified fatty acids ( = 0.006), total cholesterol ( = 0.029), and triglycerides ( = 0.001) than lean animals. The increased sensitivity due to body fat percentage for gauging alterations in plasma metabolite levels may be due to increased correlation strength. Body fat percentage correlated positively with plasma insulin (r = 0.627, = 0.002), nonesterified fatty acids (r = 0.674, < 0.001), total cholesterol (r = 0.825, < 0.0001), triglycerides (r = 0.5823, < 0.005), blood urea nitrogen (r = 0.429, < 0.05), creatinine (r = 0.490, = 0.021), and total protein (r = 0.737, < 0.0001) levels, which all tend to increase as a result of increasing adiposity.
Supplementing body fat percentage with five-point BCS appears to increase the likelihood of validating overweight status in small-medium sized dog breeds by detecting changes in plasma metabolite levels, especially lipids, induced as a result of increasing adiposity.
目前，五分制身体状况评分（BCS）在日本被兽医和临床医生广泛用于评估犬类的肥胖程度。然而，BCS评分的赋值本质上是主观的，大多数临床医生不采用半分制评分，而是倾向于将数值四舍五入，从而导致评估不够准确。因此，我们试图通过血浆代谢物验证来确定，使用简单的形态测量法评估体脂百分比并辅以五分制BCS，是否能提高检测超重中小型犬种肥胖程度增加的敏感性。
总体而言，雄性（未绝育/已绝育）犬的瘦体重脂肪百分比为15%-22%，雌性（未绝育/已绝育）犬为15%-25%。被BCS归类为超重的犬，其非酯化脂肪酸水平显著更高（P = 0.005），而被BCS + 体脂百分比归类为超重的动物，与瘦动物相比，其非酯化脂肪酸（P = 0.006）、总胆固醇（P = 0.029）和甘油三酯（P = 0.001）水平显著更高。体脂百分比用于衡量血浆代谢物水平变化的敏感性增加，可能是由于相关性强度增加。体脂百分比与血浆胰岛素（r = 0.627，P = 0.002）、非酯化脂肪酸（r = 0.674，P < 0.001）、总胆固醇（r = 0.825，P < 0.0001）、甘油三酯（r = 0.5823，P < 0.005）、血尿素氮（r = 0.429，P < 0.05）、肌酐（r = 0.490，P = 0.021）和总蛋白（r = 0.737，P < 0.0001）水平呈正相关，这些指标往往会随着肥胖程度的增加而升高。
用五分制BCS补充体脂百分比，似乎可以通过检测肥胖导致的血浆代谢物水平变化，尤其是脂质变化，来提高验证中小型犬种超重状态的可能性。
