to compare the biomarkers and the allostatic load levels in a sample of older persons with and without canine companionship.
descriptive and comparative study. Data were collected using a sociodemographic questionnaire and a fasting blood sample. The allostatic load comprised 11 biomarkers that are primary and secondary stress mediators, which arise from the following systems: neuroendocrine, immune, metabolic, cardiovascular and anthropometric.
a significant difference was found in two biomarkers: cortisol (t= -3.091, df=104, p=0.003) and total cholesterol (t= -2.566, df=104, p=0.012), in the allostatic load levels between older adults with and without a canine companionship (U= 1714.00, Z= 2.01, p=0.044). By associating the allostatic load level with the canine companionship, there was a higher frequency of older adults with low allostatic load among those who have canine companion, compared with those who do not have canine companionship. (χ2= 3.69, df=1, p= 0.043).
canine companionship influences health in a positive way, as the allostatic load is lower in older adults who have a dog as companion, in addition to presenting lower levels of cortisol and total cholesterol.
比较有和没有犬类陪伴的老年人样本中的生物标志物和应激负荷水平。
描述性和比较性研究。使用社会人口统计学问卷和空腹血样收集数据。应激负荷包括11种作为主要和次要应激介质的生物标志物，这些标志物来自以下系统：神经内分泌、免疫、代谢、心血管和人体测量学。
在有和没有犬类陪伴的老年人的应激负荷水平中，发现两种生物标志物存在显著差异：皮质醇（t = -3.091，自由度 = 104，p = 0.003）和总胆固醇（t = -2.566，自由度 = 104，p = 0.012）（U = 1714.00，Z = 2.01，p = 0.044）。通过将应激负荷水平与犬类陪伴相关联，与没有犬类陪伴的老年人相比，有犬类陪伴的老年人中应激负荷低的频率更高。（χ2 = 3.69，自由度 = 1，p = 0.043）。
犬类陪伴对健康有积极影响，因为有狗作为陪伴的老年人应激负荷较低，同时皮质醇和总胆固醇水平也较低。
