OBJECTIVE
The purposes of this study were to perform a detailed analysis how: i) the frequency of coffee/tea consumption and ii) the use of additives in coffee/tea is associated with measures of total and abdominal obesity.
METHOD
3,823 participants of the 2003-2004 National Health and Nutrition Examination Survey were examined. Obesity was assessed by BMI and waist circumference (WC). Coffee and tea consumption and use of additives were assessed by questionnaire.
RESULTS
Coffee consumption was not related to BMI or WC in either gender. However, men who drank ≥2 cups of tea per day had lower BMI (25.9 vs. 28.0 kg/m(2)) and WC (95.2 vs. 101.32 cm) values than men who never drank drink tea (p ≤ 0.05). The associations between tea consumption and BMI or WC were no longer significant after adjustment for additive use. Coffee/tea drinkers who used artificial sweeteners had larger (p ≤ 0.05) BMIs than coffee/tea drinkers who did not use sweeteners (28.2 vs. 27.1 kg/m(2) in men, 28.4 vs. 27.1 kg/m(2) in women).
CONCLUSION
Frequency of coffee/tea consumption was not associated with measures of obesity because additive use explained the association between tea consumption and obesity in men. Artificial sweetener use within coffee/tea was associated with higher BMI.
目的
本研究旨在详细分析：i）咖啡/茶的饮用频率，以及 ii）咖啡/茶中添加剂的使用，与总体肥胖和腹部肥胖的衡量标准有何关联。
方法
对 2003-2004 年全国健康与营养调查的 3823 名参与者进行了检查。通过体重指数（BMI）和腰围（WC）来评估肥胖。通过问卷调查评估咖啡和茶的消耗以及添加剂的使用。
结果
咖啡的消耗与男女两性的 BMI 或 WC 均无关。然而，每天饮用≥2 杯茶的男性的 BMI（25.9 与 28.0kg/m²）和 WC（95.2 与 101.32cm）值均低于从不饮茶的男性（p≤0.05）。调整了添加剂的使用后，茶的消耗与 BMI 或 WC 之间的关联不再显著。使用人工甜味剂的咖啡/茶饮用者的 BMI 比不使用甜味剂的咖啡/茶饮用者更大（男性为 28.2 与 27.1kg/m²，女性为 28.4 与 27.1kg/m²）（p≤0.05）。
结论
咖啡/茶的消耗频率与肥胖的衡量标准无关，因为添加剂的使用解释了男性中茶的消耗与肥胖之间的关联。咖啡/茶中人工甜味剂的使用与更高的 BMI 有关。
