Age-related physiologic and social changes to eating has been shown to affect diet and nutrition-related diseases, but it is not known whether these changes also affect physical function. A team of WHI researchers led by Dr. Marian Neuhouser examined the relationship of eating barriers on physical function in a subset of 5,910 WHI participants. Eating barriers were both psychosocial-related (i.e., eating alone, poor eating frequency, or financial burdens to obtaining food) and physical (i.e., dentition problems or physical difficulties with cooking or shopping) and were collected by a questionnaire developed by the Nutrition and Energy Balance Scientific Interest Group. Physical function was collected during an in-person clinic visit and included grip strength and components of the Short Physical Performance Battery – a balance test, timed walking speed, and a chair stand test.

Their results showed that all the barriers to eating, with the exception of eating alone, were associated with lower physical functioning. Furthermore, as the number of eating barriers a participant had increased, her level of physical functioning decreased. Since poor physical function is highly predictive of future health events and mortality, these findings emphasize the importance of addressing health and nutrition concerns related to eating and physical functioning in older women.

These findings were published in Preventative Medicine in October 2020.
