Final answer:
The National Social Life, Health, and Aging Project likely found that older respondents with intimate partners are part of a trend reflecting changing relationship practices among older adults, as cohabitation becomes more common and traditional marriage less so, all while maintaining sexual health and relationships.
Step-by-step explanation:
In the National Social Life, Health, and Aging Project, which surveyed more than 3,000 U.S. 57- to 85-year-olds, more than half of the oldest respondents with an intimate partner were likely involved in nuanced relationships that reflected the changing norms and practices around marriage, cohabitation, and sexuality in older age. This reflects broader societal trends, where cohabitation is increasing, marriage is sometimes delayed or foregone, and the traditional U.S. family structure is becoming less common. For older adults, aging and sexuality are important aspects of their quality of life and identity, and this includes those who may be part of the LGBTQ community and face unique challenges in long-term care settings. The studies collectively suggest that sexual health and relationships remain important components of life for many older adults, despite evolving social norms and the challenges that come with aging.
