The aim of this retrospective study was to assess the abdominal fat distribution in toy breed dogs using computed tomography (CT) in relation to the breed, age, and sexual status. In 140 dogs (52 Maltese, 33 Poodles, 32 Shih-Tzus, and 23 Yorkshire Terriers), the total fat area (TA), visceral fat area (VA), subcutaneous fat area (SA) and body area (BA) were measured at the third and sixth lumbar vertebral level on non-contrast transverse CT images. The differences in the TA/BA and VA/SA according to the breed, age, and sexual status, and correlations with the age were analysed. The differences in the TA/BA and VA/SA among the breeds were revealed ( < 0.05). There was no difference for the TA/BA among the sexual statuses, but the VA/SA was higher in spayed females than in intact females ( = 0.001). Positive correlation of the age with the TA/BA in the Maltese, Poodles, and intact females, and the age with the VA/SA in the Maltese, Shih-Tzus, Yorkshire Terriers, neutered males, and spayed females were found. The results showed that the abdominal fat composition varied according to the breed, age, and sex, which may have implications on defining obesity-related disease risks in different populations. Careful monitoring of the VA/SA in the breed (Maltese, Shih-Tzu, and Yorkshire Terrier), age (senior dogs), and sexual status (neutered dogs) may be required.
这项回顾性研究的目的是使用计算机断层扫描（CT）评估玩具犬种的腹部脂肪分布，并分析其与品种、年龄和性别状况的关系。对140只犬（52只马尔济斯犬、33只贵宾犬、32只西施犬和23只约克夏梗）在非增强横断CT图像上的第三和第六腰椎水平测量总脂肪面积（TA）、内脏脂肪面积（VA）、皮下脂肪面积（SA）和体表面积（BA）。分析了TA/BA和VA/SA根据品种、年龄和性别状况的差异，以及与年龄的相关性。品种间TA/BA和VA/SA存在差异（P<0.05）。性别状况间TA/BA无差异，但绝育雌性犬的VA/SA高于未绝育雌性犬（P=0.001）。发现马尔济斯犬、贵宾犬和未绝育雌性犬的年龄与TA/BA呈正相关，马尔济斯犬、西施犬、约克夏梗、去势雄性犬和绝育雌性犬的年龄与VA/SA呈正相关。结果表明，腹部脂肪组成因品种、年龄和性别而异，这可能对确定不同人群中与肥胖相关的疾病风险有影响。可能需要对特定品种（马尔济斯犬、西施犬和约克夏梗）、年龄（老年犬）和性别状况（去势犬）的VA/SA进行仔细监测。
