Caffeine is a psychoactive substance that may affect the normal course of pregnancy, therefore its intake during that time should not exceed 200 mg/day. The aim of this study was to evaluate caffeine intake among pregnant women from the Warsaw region. The study was conducted among 100 pregnant women who delivered at the Department of Obstetrics, Gynecology and Oncology, Medical University of Warsaw. Caffeine intake from coffee, tea, and energy drinks was measured using a questionnaire. Direct interviewing was used, with all interviews conducted by the same dietitian. Multiple regression analysis was used to investigate the relationship between caffeine intake and anthropometric measurements of the newborns. Mean caffeine intake among pregnant women was 68 ± 51 mg/day. Only 2% of the respondents exceeded the safe dose of 200 mg. Tea (mostly black) was the source of 63% of all caffeine. No relationships were found between caffeine intake and neonatal weight, length, or head and chest circumference ( > 0.05). Caffeine intake in our study population was relatively low and did not negatively affect fetal growth.
咖啡因是一种精神活性物质，可能会影响正常的妊娠过程，因此在此期间的摄入量不应超过 200 毫克/天。本研究旨在评估华沙地区孕妇的咖啡因摄入量。该研究在华沙医科大学妇产科和肿瘤学系分娩的 100 名孕妇中进行。使用问卷测量了来自咖啡、茶和能量饮料的咖啡因摄入量。采用直接访谈的方式，所有访谈均由同一位营养师进行。多元回归分析用于研究咖啡因摄入量与新生儿人体测量学指标之间的关系。孕妇的平均咖啡因摄入量为 68 ± 51 毫克/天。只有 2%的受访者超过了 200 毫克的安全剂量。茶（主要是黑茶）是所有咖啡因的 63%的来源。咖啡因摄入量与新生儿体重、身长或头围和胸围之间没有关系（> 0.05）。在我们的研究人群中，咖啡因摄入量相对较低，并未对胎儿生长产生负面影响。
