The role of nurses in implementation of public policy on adolescent health in Colombia, Ecuador, and Peru.

Background: In Latin America, interventions aimed at adolescents' health suffer from a shortfall of investment and lack of sustainability. Nurses, as an integral part of health services and systems, can lead the implementation and development of public health policies to improve adolescent health.

Objective: To identify and analyze the role of nurses in the development and implementation of public policies and in the provision of health care to adolescents in Colombia, Ecuador, and Peru.

Homicide among young people in the countries of the Americas.

Objective: To examine the homicide trends among young people (10-24 years), adolescents (10-19 years), and young adults (20-24 years) in 33 countries in the Americas between 2000 and 2019, with a focus on inequalities between countries in the burden of homicides.

Methods: An ecological study was performed using estimated deaths from 33 countries. Age-adjusted rates, percentage change (PC), average annual percentage change (AAPC), and relative risk (RR) were estimated; besides, analysis on social inequalities was performed.

Effectiveness of a participatory approach to develop school health interventions in four low resource cities: study protocol of the 'empowering adolescents to lead change using health data' cluster randomised controlled trial.

Introduction: Comprehensive local data on adolescent health are often lacking, particularly in lower resource settings. Furthermore, there are knowledge gaps around which interventions are effective to support healthy behaviours. This study generates health information for students from cities in four middle-income countries to plan, implement and subsequently evaluate a package of interventions to improve health outcomes.
