The aim of this study was to investigate the effects of tea on the total antioxidant capacity of saliva among smokers.
24 smokers were selected by convenience sampling. Demographic information and duration of smoking were recorded at the beginning of study. Two cups of tea were given to the participants with specific instruction for 30 days. The unstimulated saliva was collected on first day, 15 and 30 days. Then, total antioxidant capacity was measured by a special kit. Statistical analysis was conducted by repeated measure ANOVA test.
The mean values of total antioxidant capacity of saliva were significantly higher in days 15 and 30 from the baseline. (p<0.0001, P=0.006). In day 30, the mean value of antioxidant was not significantly different from day 15. (P=0.271).
tea consumption increases salivary antioxidants level in smokers.
本研究旨在调查茶对吸烟者唾液总抗氧化能力的影响。
通过便利抽样选取24名吸烟者。在研究开始时记录人口统计学信息和吸烟时长。给予参与者两杯茶，并给出具体饮用指导，为期30天。在第1天、第15天和第30天收集非刺激性唾液。然后，使用专用试剂盒测量总抗氧化能力。采用重复测量方差分析进行统计分析。
唾液总抗氧化能力的平均值在第15天和第30天显著高于基线水平。（p<0.0001，P=0.006）。在第30天，抗氧化剂的平均值与第15天无显著差异。（P=0.271）。
饮茶可提高吸烟者唾液中的抗氧化剂水平。
