What does the term "gerontology" refer to?

The term "gerontology" specifically refers to the study of aging and the various issues that affect the elderly population. This field encompasses a wide range of disciplines, including biology, sociology, psychology, and public health, and focuses on understanding the aging process, the challenges faced by older adults, and the social and policy implications of an aging society. Gerontologists analyze factors such as the healthcare needs, mental health, social engagement, and quality of life of older individuals, providing insights that can help improve care and support for this demographic.

The other choices do not accurately reflect the definition of gerontology, as they pertain to different fields or focus. For instance, the study of nursing practices is a separate area of healthcare education and research. Similarly, the field of medicine dealing with young adults does not relate to gerontology. Finally, the analysis of healthcare policies, while related to the care of various populations, does not specifically focus on the aging process or the unique challenges of the elderly.
