[One hundred years of health in a demographic, epidemiological and public policy context: the transition of childhood morbidity and its challenges]. / Cien años de salud en un contexto demográfico, epidemiológico y de políticas públicas: la transición de la morbilidad infantil y sus desafíos.

ABSTRACT

Chile is in an advanced stage of demographic and epidemiological transition. It is in this scenario that the political, economic and health crisis occurred, with the social outbreak in 2019 and then the COVID-19 pandemic. The mortality of children and adolescents dropped significantly, however, changes in lifestyles and demotivation, associated with long confinement and worsening health of parents and caregivers triggered an epidemic of mental health, developmental and nutritional problems. Pediatricians were forced to reinvent themselves, exposing themselves to stress and burnout. The aim of the manuscript is to describe the demographic, epidemiological and public policy context of child health in Chile in the last century, as a backdrop to dimension the immediate impact of the COVID-19 pandemic. The new health challenges for this age group in the medium and long term are discussed. Some theories, conceptualizations, and relevant milestones of the public health system in Chile are presented. The emergence of "post-pandemic morbidity", such as sedentary lifestyle, food insecurity, screen addiction, identity conflicts, violence, mental health disorders and reemergence of morbidity and mortality due to infectious and contagious diseases is discussed. Professionals responsible for the care of children must redouble their efforts to provide comprehensive care, accompanying families in the new challenges, in order to rehabilitate a healthy childhood.
