Respondent-driven sampling for an adolescent health study in vulnerable urban settings: a multi-country study.

The global adolescent population is larger than ever before and is rapidly urbanizing. Global surveillance systems to monitor youth health typically use household- and school-based recruitment methods. These systems risk not reaching the most marginalized youth made vulnerable by conditions of migration, civil conflict, and other forms of individual and structural vulnerability.

Social capital and vulnerable urban youth in five global cities.

Purpose: Social capital is essential for the successful development of young people. The current study examines direct measures of social capital in young people in five urban global contexts.

Methods: The Well-Being of Adolescents in Vulnerable Environments is a global study of young people aged 15-19 years living in disadvantaged, urban settings.

Employment and training programs: a context for reaching out of school youth with mental health and other health programs.

Youth who have dropped out of school engage in risky health behaviors and have limited access to health care. It is difficult for health experts to develop programs that successfully reach this population. Employment and training programs for youth who have dropped out are a potential venue for addressing the many health needs of these youth.
