Final answer:
A significant percentage of older adults have at least one chronic health condition, with arthritis affecting 50% of those over sixty-five, suggesting a high overall prevalence.
Step-by-step explanation:
Regarding the percentage of older adults with at least one chronic health condition, the data provided speaks to a variety of health issues prevalent in those over sixty-five years old. From the information given, it is clear that a significant percentage of older adults suffer from chronic conditions. The most frequently reported health issues among this age group are arthritis (50 percent), hypertension (38 percent), heart disease (32 percent), and cancer (22 percent). Moreover, the trend noted by Parker and Thorslund indicates increasing levels of functional impairments and chronic diseases. Taking into account that these conditions are common among older adults,
The percentage of older adults with at least one chronic health condition is likely very high, given that arthritis alone affects 50 percent. This suggests that the correct answer to the multiple-choice question is potentially 'D: 75' if one refers specifically to adults over sixty-five.
