New horizons in advancing lifestyle medicine for older adults utilizing a transdisciplinary approach: gaps and opportunities.

Nearly half of premature deaths can be prevented with healthy lifestyle behaviours. However, most older adults do not adhere to established guidelines to promote a healthy lifestyle. We propose a tailored framework of lifestyle medicine that acknowledges the complex contexts and care needs of older adults. The proposed framework of lifestyle medicine for older adults integrates their lived experiences (e.g. social determinants of health, built environment), the 5 M framework of geriatric medicine (i.e. Mind, Mobility, Medications, Multicomplexity, Matters Most) and the six pillars of lifestyle medicine (i.e. nutrition/diet, physical activity/exercise, restorative sleep, stress management, avoidance of risky substances, positive social connections) through a novel transdisciplinary approach. Guided by the updated framework, key gaps and opportunities are presented to advance lifestyle medicine practice, research and policy with the goal of promoting sustained behaviour change and improving the healthspan of older adults.
