Along with groups such as the United Nations and the Bill and Melinda Gates Foundation, the World Health Organization's Child and Adolescent Health and Development (CAH) division is concerned with the health and well-being of those who range in age from the newly born to age nineteen. It is, as they point out on their website, a rather large group of individuals, and all told, it comprises approximately 40% of the world's inhabitants. From their homepage, interested parties can learn about their primary areas of focus, and also look over a thorough list of their recent publications. Other sections include those dedicated to providing data about nutritional portraits of infants in different parts of the world and neonatal care. Visitors will also be glad to learn that the site and its materials are available in Spanish, Russian, French, and English.
