A global public health and child advocacy movement has emerged in recent years that focuses on children’s environmental health. This movement developed out of the growing recognition that women’s and children’s exposures to environmental chemicals are widespread, health outcomes thought to be caused by environmental exposures are increasing among women and children, and governmental regulation of environmental toxicants does not take children’s unique vulnerabilities into account [1, 2]. Many MCH professionals are actively involved in this movement. They hold positions at all levels, including leadership positions, in academic centers, research programs, government agencies, professional societies, and advocacy organizations that address the impact of environmental exposures on children’s health and development [3–5]. In addition, there have been attempts to get the MCH field—as defined in the US by formal MCH training programs and their faculties, programs funded by the Maternal and Child Health Block Grant, professional associations, and this journal—to recognize the relevance of children’s environmental health to its mission. Kotelchuck called for such recognition as early as 1996 [6]. Leiss presented a course syllabus on children’s environmental health developed specifically for MCH students [7]. The MCH section of the American Public Health Association has in the past (but not presently) had an environmental health committee. The authors know of faculty at two different schools of public health who offered to teach courses on this topic under the aegis of their respective MCH departments. (Both of the MCH departments declined the offers.) These efforts have not succeeded in changing the mindset of our field, which still does not recognize the importance to its goals of women’s and children’s environmental exposures. Except for a limited focus on lead and tobacco smoke, environmental health as a topic is absent from the agendas of the major US MCH organizations. It is not present among the issues, projects, and resources highlighted on their websites, nor is it featured at their conferences [8–12]. (The 2009 MCH Epidemiology Conference will include, for the first time, a plenary session on this topic [13].) It is not included among collected MCH course syllabi [10] or in MCH textbooks [14], and it is not part of the core competencies that guide MCH training programs [15]. Environmental health issues are not mentioned in the funding announcements for training programs of the Maternal and Child Health Bureau (except for one brief mention in the schools of public health and pediatric pulmonary center guidances). Articles on this topic in the MCH Journal are rare. Clearly, children’s environmental health is not currently part of our ‘‘corporate consciousness.’’ It is true that many MCH students have access to courses in perinatal epidemiology and reproductive health that consider the role of environmental exposures. But in most Addressing women’s and children’s exposure to environmental toxicants is fundamental to achieving the goals of the MCH field. Children’s environmental health should be part and parcel of MCH training, research, and practice in the twenty-first century.
