To evaluate the effect of signalment and body conformation on activity monitoring in companion dogs.
104 companion dogs.
While wearing an activity monitor, each dog was led through a series of standard activities: lying down, walking laps, trotting laps, and trotting up and down stairs. Linear regression analysis was used to determine which signalment and body conformation factors were associated with activity counts.
There was no significant effect of signalment or body conformation on activity counts when dogs were lying down, walking laps, and trotting laps. However, when dogs were trotting up and down stairs, there was a significant effect of age and body weight such that, for every 1-kg increase in body weight, there was a 1.7% (95% confidence interval, 1.1% to 2.4%) decrease in activity counts and for every 1-year increase in age, there was a 4.2% (95% confidence interval, 1.4% to 6.9%) decrease in activity counts.
When activity was well controlled, there was no significant effect of signalment or body conformation on activity counts recorded by the activity monitor. However, when activity was less controlled, older dogs and larger dogs had lower activity counts than younger and smaller dogs. The wide range in body conformation (eg, limb or body length) among dogs did not appear to significantly impact the activity counts recorded by the monitor, but age and body weight did and must be considered in analysis of data collected from the monitors.
评估体征和身体形态对伴侣犬活动监测的影响。
104只伴侣犬。
每只犬佩戴活动监测器时,依次进行一系列标准活动:躺下、走圈、小跑圈以及上下楼梯小跑。采用线性回归分析确定哪些体征和身体形态因素与活动计数相关。
犬躺下、走圈和小跑圈时,体征或身体形态对活动计数无显著影响。然而,犬上下楼梯小跑时,年龄和体重有显著影响,即体重每增加1千克,活动计数下降1.7%(95%置信区间为1.1%至2.4%),年龄每增加1岁,活动计数下降4.2%(95%置信区间为1.4%至6.9%)。
当活动得到良好控制时,体征或身体形态对活动监测器记录的活动计数无显著影响。然而,当活动控制较差时,老年犬和体型较大的犬的活动计数低于年轻犬和体型较小的犬。犬之间身体形态(如肢体或身体长度)的广泛差异似乎对监测器记录的活动计数没有显著影响,但年龄和体重有影响,在分析从监测器收集的数据时必须予以考虑。
