abstract="It is unknown if physical activity and diet quality are associated with the risk of poor outcomes, such as mortality, among prefrail and frail older adults. This was a population-based cohort study among 1487 prefrail and frail older-adults from the Third National Health and Nutrition Survey. Compared to participants who were sedentary (0 bouts of physical activity per week), those who were physically inactive (1-4 bouts of physical activity per week) were 24% less likely to die [HR: 0.76 (95% CI: 0.58-0.98)], and those who were physically active (≥5 bouts of physical activity per week) were 34% less likely to die [HR: 0.66 (95% CI: 0.51-0.86); Ptrend = 0.002]. Compared to participants with poor diet quality, those with fair diet quality were 26% less likely to die [HR: 0.74 (95% CI: 0.52-0.98)], and those with good diet quality were 33% less likely to die [HR: 0.67 (95% CI: 0.55-1.00); Ptrend = 0.050]. There was a synergistic interaction between physical activity and diet quality on the risk of mortality (Pinteraction = 0.058). Participation in physical activity and consumption of a healthy diet is associated with a lower risk of mortality among prefrail and frail older adults.<p /> <p>Language: en</p>",
