What did studies of Senior-friendly diet find?

10

Studies of Senior-friendly diet measured 10 outcomes; the most studied are physical functioning (1 study), quality-adjusted life expectancy (1) and health-related quality-of-life utility weights (1).

Physical functioning

1 study

  1. Senior-friendly diet improves physical functioning in humans (-0.266, p < 0.05).

    “The estimated effects are −0.266 (p < 0.05) for mobility, −0.087 (p < 0.05) for self-care, −0.134 (p < 0.05) for usual activities, −0.281 (p < 0.05) for pain/discomfort, and −0.178 (p < 0.05) for anxiety/depression.”

  2. Senior-friendly diet improves physical functioning in humans.

    “These overall gains were primarily driven by significant enhancements in physical functioning, specifically in mobility, self-care, usual activities, and the reduction of pain and discomfort.”

Quality-adjusted life expectancy

1 study

  1. Senior-friendly diet increases quality-adjusted life expectancy in humans (0.655, SE = 0.142, p < 0.01).

    “The coefficient on treatment effect is 0.053 (SE = 0.013, p < 0.01) for utility weight and 0.655 (SE = 0.142, p < 0.01) for QALE.”

  2. Senior-friendly diet increases quality-adjusted life expectancy in humans.

    “consuming the senior-friendly diet led to statistically significant improvements in both utility weights and quality-adjusted life expectancy.”
