Since the start of the human immunodeficiency virus (HIV) pandemic, numerous biomedical advances have caused the social-work response to shift from management of a crisis to prevention of an incurable, but treatable chronic disease. About 1.3 million people in the United States and more than 33 million people worldwide are estimated to be living with HIV. Rates of incidence in impoverished, marginalized communities are highest, with the rates continuing to increase among young African American gay and bisexual men. Other communities at high risk are people who are incarcerated, engage in sex work or other kinds of exchange sex, and participate in risky injection-drug use. Minority groups are often impacted because of reduced access to quality medical care and HIV testing. Social workers in HIV prevention work are challenged to educate clients and communities on the sexual risk continuum, provide more interventions that are culturally tailored for disadvantaged at-risk groups, and implement evidence-based HIV prevention and testing programs worldwide. The National HIV/AIDS Strategy now provides structure to funding opportunities for HIV prevention programs, and there is disparate access to effective treatments worldwide for those living with HIV.

Scientific findings from social sciences, neurobiology, endocrinology, and immunology highlight the adaptive benefits of positive emotion and activity to both mental and physical health. Positive activity, such as engagement with music and exercise, can also contribute to favorable health outcomes. This article reviews scientific evidence of the adaptive benefits of positive emotion and activity throughout the life course, with examples drawn from the fetal environment through late adulthood. Specifically, the text weaves together theory and empirical findings from an interdisciplinary literature to describe how positive emotion and activity help to build important cognitive, social, and physical resources throughout the life course.

This entry focuses on the transition to independent living process required of youth and young adults who are “aging out” of the foster care system. It addresses the multiple risks and challenges faced by young people who are aging out of care and those of young adults who have “aged out.” This entry addresses existing policies and programs intended to assist youth who are transitioning from care. Current research findings about the experience of these youth over time both prior to and after exiting foster care are presented. Finally, the unique risks and challenges faced by as well as existing resources for LGBTQ youth who are in the process of or who have aged out are presented as an exemplar of unique needs and experiences of youth from vulnerable populations. Attention is also given to the strengths and resiliency of many former foster care youth who successfully make the transition from foster care to independent living.
