El embarazo en la adolescencia es considerado como un riesgo para la salud materna e infantil, así como un factor que contribuye al desmesurado crecimiento de la población, a la deserción escolar, y a la perpetuación de la pobreza, al coartar las posibilidades de desarrollo familiar. Sus causas se atribuyen principalmente a la sexualidad precoz y a la falta de información y de acceso a los métodos anticonceptivos. Esta publicación pone en cuestión los supuestos antes mencionados, destacando dos factores realmente subyacentes a esta problemática: la pobreza y la desigualdad, que dejan pocas oportunidades alternativas de desarrollo a una gran cantidad de nuestros jóvenes, y la falta de una verdadera educación para el ejercicio de la sexualidad que les permita enfrentarse con responsabilidad a este aspecto tan central para su vida.

Providing a critical review of the current state of health promotion research. This book re-conceptualises the field of health promotion as collaborative and integrating enterprise, rather than as a battlefield for disciplinary and intellectual clashes. It makes a significant contribution to ongoing epistemological, theoretical and methodological debates in health promotion research. With contributors from Sweden, Switzerland, Denmark, Ireland, the UK and the US, Researching Health Promotion will be of interest to students and professionals working in health promotion, public health, medicine and health policy.

International in scope, The Handbook of Global Health Communication offers a comprehensive and up-to-date analysis of the role of communication processes in global public health, development and social change Brings together 32 contributions from well-respected scholars and practitioners in the field, addressing a wide range of communication approaches in current global health programs Offers an integrated view that links communication to the strengthening of health services, the involvement of affected communities in shaping health policies and improving care, and the empowerment of citizens in making decisions about health Adopts a broad understanding of communication that goes beyond conventional divisions between informational and participatory approaches

"This volume is a textbook on linear control systems with an emphasis on stochastic optimal control with solution methods using spectral factorization in line with the original approach of N. Wiener. Continuous-time and discrete-time versions are presented in parallel.... Two appendices introduce functional analytic concepts and probability theory, and there are 77 references and an index. The chapters (except for the last two) end with problems.... [T]he book presents in a clear way important concepts of control theory and can be used for teaching." —Zentralblatt Math "This is a textbook intended for use in courses on linear control and filtering and estimation on (advanced) levels. Its major purpose is an introduction to both deterministic and stochastic control and estimation. Topics are treated in both continuous time and discrete time versions.... Each chapter involves problems and exercises, and the book is supplemented by appendices, where fundamentals on Hilbert and Banach spaces, operator theory, and measure theoretic probability may be found. The book will be very useful for students, but also for a variety of specialists interested in deterministic and stochastic control and filtering." —Applications of Mathematics "The strength of the book under review lies in the choice of specialized topics it contains, which may not be found in this form elsewhere. Also, the first half would make a good standard course in linear control." —Journal of the Indian Institute of Science

The topics covered in the book cover different aspects of sexual and reproductive health. This book provides novel research results that may be essential as a basis for the development of health policies and strategies in sexual and reproductive health. These policies are necessary to achieve greater health protection. Among others, issues as important as the increase in STIs, their risk factors, vulnerable situations and populations, as well as the issue of priority in reproductive health, such as the care that must be provided during pregnancy and childbirth in order to guarantee healthy women and children, are developed in the book. There is no doubt that women should be the preferential recipients of these health policies and strategies and, therefore, pathologies that have an impact on their quality of life as well as the situations of gender violence that these women experience also occupy a place within the content of this book. In this book, you can find interesting results allowing researchers to take into account in proposing new lines of research, students and academics to receive and transmit the most current and relevant knowledge, political leaders to develop adequate and efficient health policies and strategies, and clinical health professionals to work in clinical practice with the best available scientific evidence.

Tanto padres como educadores, somos los responsables de proporcionar una educación sexual y afectiva completa a nuestros menores, no podemos relegar a un segundo plano los contenidos que contribuyen a la consecución de tales objetivos y es por ello que debemos incluir dentro de las materias del marco educativo actual, la educación sexual de los individuos que se están formando, sabiendo que de esta forma estamos contribuyendo al logro de conseguir seres felices.

This book contains the latest information on surveillance by the international public health community, including: the WHO's Stepwise Approach, the U.S.'s Behavioral Risk Factor Surveillance System, the Finbalt Health Monitor, the EURALIM Experience, and the Mega Country Health Promotion Network. It is for those involved in planning or conducting chronic disease risk factor surveillance and for those interested in developing a global network of persons involved in this arena.
