■这项研究的目的是确定咖啡消费对年轻人唾液皮质醇(sCort)和α淀粉酶(sAA)的影响。
■60名健康的大学生,习惯性的咖啡消费者,参加了这项描述性观察研究。参与者分为三组:G1低消费量(每天≤2杯咖啡,n=20),G2适度消费(每天2-5杯咖啡,n=20),和G3高消费(每天>5杯咖啡,n=20)。唾液自我收集是在早上(6:30-7:30AM)和晚上(08:00-09:00PM)。通过动力学方法使用化学发光和sAA活性分析sCort。使用Studentt检验和方差分析对数据进行统计学分析。
■样本由30名女性和30名男性组成,年龄在20至35岁之间。在所有组中,上午sCort值较高(AM0,29±0,19vs.PM0,09±0,05µg/dl,p<0.0001)。相比之下,夜间sAA水平较高(PM160,16±60,42vs.AM32,79±12,98U/ml,p<0.0001)。没有检测到显著差异,在Corts和AAs的内容中,群体之间。
■:咖啡消费,在非压力条件下,没有改变年轻人的索尔特和sAA的水平和模式。
UNASSIGNED: The purpose of this study was to determine the effects of coffee consumption on salivary cortisol (sCort) and alpha amylase (sAA) in young adults.
UNASSIGNED: Sixty healthy university students, habitual coffee consumers, participated in this descriptive observational study. Participants were divided into three groups: G1 low consumption (≤ 2 cups of coffee per day, n = 20), G2 moderate consumption (2-5 cups of coffee per day, n = 20), and G3 high consumption (>5 cups of coffee per day, n = 20). Saliva self-collection was in the morning (6:30-7:30 AM) and at night (08:00-09:00 PM). sCort was analyzed using chemiluminescence and sAA activity by kinetic method. Statistical analysis of the data was performed using Student\'s t-test and analysis of variance.
UNASSIGNED: The sample consisted of 30 women and 30 men, aged between 20 and 35 years. In all groups, sCort values were higher in the morning (AM 0,29 ± 0,19 vs. PM 0,09 ± 0,05 µg/dl, p < 0.0001). In contrast, sAA levels were higher in the night (PM 160,16 ± 60,42 vs. AM 32,79 ± 12,98 U/ml, p < 0.0001). No significant differences were detected, in the contents of Corts and AAs, between the groups.
UNASSIGNED: : Coffee consumption, in non-stressful conditions, did not alter levels and patterns of sCort and sAA in young adults.
