What factor may contribute to the increased social vulnerability of older adults?

The correct answer highlights the significant impact that retirement, loss of a spouse, and decreased mobility have on the social vulnerability of older adults. As individuals age, they often face a transition from active employment to retirement, which can lead to a loss of social connections and identity associated with their work life. The death of a spouse can further exacerbate feelings of loneliness and isolation, as many older adults rely on their partners for emotional support and companionship.

Additionally, decreased mobility, whether due to physical health issues or the natural aging process, can limit an older adult's ability to participate in social activities, access community resources, and maintain relationships with friends and family. Together, these factors create a scenario where older adults may experience increased isolation, a lack of social support, and a heightened risk of mental health issues, which collectively contribute to their social vulnerability. Understanding these dynamics is crucial for providing appropriate support and resources to this population.
