Intake of caffeine and other methylxanthines during pregnancy and risk for adverse effects in pregnant women and their foetuses


Book Description

The first part of the report deals with occurrence of methylxanthines in foods, beverages, and medicines, and estimates of caffeine intake. In addition, a short review of the pharmacological and toxicological actions of caffeine is given. The second and main part of the report reviews available information from epidemiological studies on the potential health hazards to the human foetus associated with parental intake during pregnancy of caffeine and related methylxanthines in foods, beverages and medicines. The studied adverse effects are influence on fertility, spontaneous abortion, congenital malformation, pre-term delivery, foetal growth retardation, foetal behaviour and effects on neonates, infants and young children. The conclusion of the report demonstrates the need for limiting caffeine exposure during pregnancy. The Nordic Working Group on Food Toxicology and Risk Evaluation (NNT) recognizes that the human exposure to caffeine and related compounds causes a spectrum of pharmacological effects, for instance cardiovascular, renal, neurological and behavioural effects. The increasing use of caffeine and related methylxanthines in various foods and beverages consumed by children and adolescents cause concern. NNT recommends that a full hazard characterization of caffeine and related methylxanthines should be performed with the aim to reach a conclusion about the upper safe level of intake of these compounds.




Caffeine for the Sustainment of Mental Task Performance


Book Description

This report from the Committee on Military Nutrition Research reviews the history of caffeine usage, the metabolism of caffeine, and its physiological effects. The effects of caffeine on physical performance, cognitive function and alertness, and alleviation of sleep deprivation impairments are discussed in light of recent scientific literature. The impact of caffeine consumption on various aspects of health, including cardiovascular disease, reproduction, bone mineral density, and fluid homeostasis are reviewed. The behavioral effects of caffeine are also discussed, including the effect of caffeine on reaction to stress, withdrawal effects, and detrimental effects of high intakes. The amounts of caffeine found to enhance vigilance and reaction time consistently are reviewed and recommendations are made with respect to amounts of caffeine appropriate for maintaining alertness of military personnel during field operations. Recommendations are also provided on the need for appropriate labeling of caffeine-containing supplements, and education of military personnel on the use of these supplements. A brief review of some alternatives to caffeine is also provided.

Preterm Birth


Book Description

The increasing prevalence of preterm birth in the United States is a complex public health problem that requires multifaceted solutions. Preterm birth is a cluster of problems with a set of overlapping factors of influence. Its causes may include individual-level behavioral and psychosocial factors, sociodemographic and neighborhood characteristics, environmental exposure, medical conditions, infertility treatments, and biological factors. Many of these factors co-occur, particularly in those who are socioeconomically disadvantaged or who are members of racial and ethnic minority groups. While advances in perinatal and neonatal care have improved survival for preterm infants, those infants who do survive have a greater risk than infants born at term for developmental disabilities, health problems, and poor growth. The birth of a preterm infant can also bring considerable emotional and economic costs to families and have implications for public-sector services, such as health insurance, educational, and other social support systems. Preterm Birth assesses the problem with respect to both its causes and outcomes. This book addresses the need for research involving clinical, basic, behavioral, and social science disciplines. By defining and addressing the health and economic consequences of premature birth, this book will be of particular interest to health care professionals, public health officials, policy makers, professional associations and clinical, basic, behavioral, and social science researchers.
