摘要

饮食调查估计，伦敦孕妇的咖啡因摄入量平均为1.4毫摩尔(270毫克)，范围为0至6.0毫摩尔(0-1160毫克)/天。平均血浆咖啡因为6.5 μ mol/l (SD 2.8 ~ 14.8)，血浆茶碱为2.9 μ mol/l (SD 1.3 ~ 6.7)，血浆可可碱为2.1 μ mol/l (SD 0.9 ~ 4.9)。饮食调查的结果显示出相当的相关性(r = 0.59;P < 0.01)与血浆咖啡因水平有关，但这些调查最好被视为咨询的基础，而不是对摄入量的准确估计。

Caffeine, theophylline and theobromine in pregnancy.

Dietary surveys estimated the caffeine intake of pregnant women in London to average 1.4 mmol (270 mg) with a range of 0 to 6.0 mmol (0-1160 mg)/day. The average plasma caffeine was 6.5 (SD 2.8-14.8), plasma theophylline 2.9 (SD 1.3-6.7), plasma theobromine 2.1 (SD 0.9-4.9) mumol/l. The results of the dietary surveys showed a fair correlation (r = 0.59; p less than 0.01) with plasma caffeine levels, but the surveys are best regarded as a basis for counseling rather than an accurate estimate of intake.
