Total body scans were performed on 89 domestic cats of various ages, using dual energy x-ray absorptiometry (DEXA) to determine body composition, including fat, lean, and bone mineral content. Bone mineral density results from scans also are presented.
This cross sectional study included data for cats from a closed colony and from privately owned cats. Data were grouped by age and were analyzed by sex and reproductive status to provide information as to the rate of growth of the individual components of body composition.
The results indicate that the rate of accretion of bone mineral, fat, and lean tissue differs throughout maturation and by sex. Regressions are provided to highlight age- and sex-related differences.
The results of this study emphasize the benefits of examining the growth of each component of body composition when studying the effects of nutrition, disease processes, or therapeutic interventions.
使用双能X线吸收法（DEXA）对89只不同年龄的家猫进行全身扫描，以确定身体成分，包括脂肪、瘦肉和骨矿物质含量。还呈现了扫描所得的骨矿物质密度结果。
这项横断面研究纳入了来自封闭猫群和私人饲养猫的数据。数据按年龄分组，并按性别和生殖状态进行分析，以提供有关身体成分各组成部分生长速率的信息。
结果表明，骨矿物质、脂肪和瘦肉组织的积累速率在整个成熟过程中因性别而异。提供了回归分析以突出年龄和性别相关差异。
本研究结果强调了在研究营养、疾病过程或治疗干预的影响时，检查身体成分各组成部分生长情况的益处。
