Caffeine Intake During Pregnancy and Neonatal Anthropometric Parameters

Abstract

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 (p > 0.05). Caffeine intake in our study population was relatively low and did not negatively affect fetal growth.

Efectos fisiológicos y cognitivos de la cafeína en la infancia: Revisión sistemática de la literatura

“…Por otro lado, en esta revisión sistemática se excluyeron los estudios que trataran de la exposición a la cafeína en útero, debido a que se consideró que el poco control experimental sobre las variables extrañas podría ser un factor de sesgo en los resultados en los escolares. No obstante, las autoras de esta revisión consideran que los trabajos descartados sobre el tema [20][21][22] , podrían ser analizados para futuras investigaciones.…”

“…El inicio de exposición de los niños a la cafeína puede suceder desde el momento de la concepción a través de la placenta 20 , durante el nacimiento ante circunstancias específicas de salud, o bien a lo largo de la infancia. No obstante, los efectos que produce a posteriori, no están bien establecidos debido a la dificultad de controlar las variables extrañas 21,22 . Al respecto, se considera necesario indagar en la literatura cuáles son los efectos cognitivos y fisiológicos en diferentes períodos de la niñez y en condiciones patológicas particulares como la apnea y alteraciones paidopsiquiátricas.…”

Extraction-Free, Direct Determination of Caffeine in Microliter Volumes of Beverages by Thermal Desorption-Gas Chromatography Mass Spectrometry

“…ese benefits result not from the initial increase in heart rate and blood pressure but from the blocking of adenosine receptors responsible for the feelings of fatigue by similarly structured caffeine. Nevertheless, concerns have arisen regarding caffeine consumption by vulnerable groups, such as children [13,14] or during pregnancy [15,16]. Excessive caffeine consumption has been known to lead to the condition "caffeinism," reported to be characterised by tinnitus, mood swings, diarrhoea, delirium, muscle tension, and tremors [17,18].…”

“…Even when purchased from the same vendor, they can vary by as much as 46% from day-to-day [23]. is can present an issue for those wishing to monitor their caffeine consumption for religious [26], sporting [10][11][12], or medical reasons [2,15] and can be a problem for suppliers and manufactures [27].…”

“…furthermore, caffeine cause mainly its biological outcomes through inhibiting all kinds of adenosine receptors and increasing the catecholamine concentrations within the mother among the fetus, leading to reduced placental blood ow and hinders placental nutrient and oxygen transport to the fetus [9][10].…”
