OBJECTIVE
The purpose of this study was to determine the effects of coffee consumption on salivary cortisol (sCort) and alpha amylase (sAA) in young adults.
MATERIALS AND METHODS
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.
RESULTS
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.
CONCLUSION
: Coffee consumption, in non-stressful conditions, did not alter levels and patterns of sCort and sAA in young adults.
目的
本研究旨在确定饮用咖啡对年轻成年人唾液皮质醇（sCort）和α淀粉酶（sAA）的影响。
材料与方法
60名有喝咖啡习惯的健康大学生参与了这项描述性观察研究。参与者被分为分为三组：G1低摄入量组（每天≤2杯咖啡，n = 20），G2中等摄入量组（每天2 - 5杯咖啡，n = 20），以及G3高摄入量组（每天>5杯咖啡，n = 20）。唾液自行采集时间为早晨（上午6:30 - 7:30）和晚上（晚上8:00 - 9:00）。采用化学发光法分析sCort，用动力学方法分析sAA活性。数据的统计分析采用学生t检验和方差分析。
结果
样本包括30名女性和30名男性，年龄在20至35岁之间。在所有组中，早晨的sCort值更高（上午0.29±0.19 vs. 下午0.09±0.05μg/dl，p < 0.0001）。相反，晚上的sAA水平更高（下午160.16±60.42 vs. 上午32.79±12.98 U/ml，p < 0.0001）。各组之间在Corts和AAs含量方面未检测到显著差异。
结论
在无压力条件下，饮用咖啡不会改变年轻成年人sCort和sAA的水平及模式。
