To study adults border-selling tea consumption in border areas in Tibet,Qinghai,and Inner Mongolia and provide the scientific data for the risk assessment of hazards and nutrients,this paper adopted multistage stratified random sampling to investigate the consumption pattern of 837 adults drinking border-selling tea in Tibet,Qinghai,and Inner Mongolia by 24-hour retrospective method.The results showed that all adults in these three areas generally drank milk tea or butter tea,with a drinking tea rate of 100%.The consumption frequency distribution of border-selling tea in adult consumers in border areas was skewed.The range of daily consumption was0.19 ~144.89 g,the average daily consumption was 14.46 g,the median value was 6.72 g,high daily consumption(P95) was 50.32 g.There was no significant difference of the average consumption of tea between male and female adult consumers among the three provinces(male:13.75 g/d;female15.10 g/d),but the regional differences were observed,the average consumption levels of border-selling tea in Tibet,Inner Mongolia and Qinghai were 23.19 g and 12.88 g and 7.07 g.The border-selling tea consumption of adults in these three areas was significantly higher than that of adults in other regions of China.The average daily consumption of border-selling tea was high.When assessing the risk of drinking tea,the health risk of residents drinking border-selling tea should be concerned.
