The Role Of Environmental Hazards In Premature Birth

Each year in the United States approximately 440,000 babies are born premature. These infants are at greater risk of death, and are more likely to suffer lifelong medical complications than full-term infants. Clinicians and researchers have made vast improvements in treating preterm birth; however, little success has been attained in understanding and preventing preterm birth. Understanding the complexity of interactions underlying preterm birth will be needed if further gains in outcomes are expected. The Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine sponsored a workshop to understand the biological mechanism of normal labor and delivery, and how environmental influences, as broadly defined, can interact with the processes of normal pregnancy to result in preterm birth. This report is a summary of the main themes presented by the speakers and participants.

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.

Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.

Each year in the United States, 250,000 infants are born too soon, weighing too little. For these low birth weight, premature infants, the future is uncertain, since they are at risk for a variety of serious medical and developmental problems—including behavioral and learning disorders that may have damaging effects for the rest of their lives. The extent to which a comprehensive early intervention program could improve or prevent these adverse outcomes was examined in the Infant Health and Development Program, a randomized controlled trial involving almost 1,000 infants in eight cities in the United States. This book describes in detail the program, its research methodology, the progress of the program, and the results of the clinical trial. The program was administered by an interdisciplinary team composed of physicians, biostatisticians, child development specialists, and researchers from several disciplines. It was instituted upon the discharge of the infants from the neonatal nursery and was maintained for three years. One-third of the infants were randomly assigned to an intervention group, the remainder to a follow-up group. Infants in both groups received pediatric care and community referral services, but only those in the intervention group participated in a program that included extensive home visits, attendance at a child development center, and group meetings for parents. The results of the program proved to be clinically important; at age three, the children in the intervention group had significantly higher IQ scores, greater cognitive development, and fewer behavioral problems. The implications of the findings for public policy are equally important, for there is increasing interest in the prevention, early detection, and management of developmental disabilities in children, as evidenced by such legislation as the Education for All Children Act. Strategies to minimize the problems of low birth weight children, with their potential for long-term savings through the prevention of disabilities and their attendant costs, could have significant repercussions in such governmental areas as medical care, education, and social welfare.

A troubling study of the role that medical racism plays in the lives of black women who have given birth to premature and low birth weight infants Black women have higher rates of premature birth than other women in America. This cannot be simply explained by economic factors, with poorer women lacking resources or access to care. Even professional, middle-class black women are at a much higher risk of premature birth than low-income white women in the United States. Dána-Ain Davis looks into this phenomenon, placing racial differences in birth outcomes into a historical context, revealing that ideas about reproduction and race today have been influenced by the legacy of ideas which developed during the era of slavery. While poor and low-income black women are often the “mascots” of premature birth outcomes, this book focuses on professional black women, who are just as likely to give birth prematurely. Drawing on an impressive array of interviews with nearly fifty mothers, fathers, neonatologists, nurses, midwives, and reproductive justice advocates, Dána-Ain Davis argues that events leading up to an infant’s arrival in a neonatal intensive care unit (NICU), and the parents’ experiences while they are in the NICU, reveal subtle but pernicious forms of racism that confound the perceived class dynamics that are frequently understood to be a central factor of premature birth. The book argues not only that medical racism persists and must be considered when examining adverse outcomes—as well as upsetting experiences for parents—but also that NICUs and life-saving technologies should not be the only strategies for improving the outcomes for black pregnant women and their babies. Davis makes the case for other avenues, such as community-based birthing projects, doulas, and midwives, that support women during pregnancy and labor are just as important and effective in avoiding premature births and mortality.

The seventh edition of the Canadian Immunization Guide was developed by the National Advisory Committee on Immunization (NACI), with the support ofthe Immunization and Respiratory Infections Division, Public Health Agency of Canada, to provide updated information and recommendations on the use of vaccines in Canada. The Public Health Agency of Canada conducted a survey in 2004, which confi rmed that the Canadian Immunization Guide is a very useful and reliable resource of information on immunization.
