Food insecurity is rising among older adults, especially those with physical limitations. Difficulty with daily activities significantly increases the risk of very low food security in this population.
Area of Science:
- Gerontology
- Public Health
- Nutrition Science
Background:
- Food insecurity has more than doubled among U.S. older adults since 2001.
- This issue is more prevalent in frail older adults, posing a significant public health concern due to the aging population.
- Physical functioning and adequate food intake are critical for the well-being of older adults.
Purpose of the Study:
- To examine the association between different domains of physical limitations and food security status in U.S. older adults.
- To identify specific physical activities that are strongly correlated with food insecurity.
- To inform public health interventions aimed at improving food security for aging populations.
Main Methods:
- Utilized data from the National Health and Nutrition Examination Survey (2007-2012) for participants aged 60 and older (n=5969).
- Defined physical limitations based on difficulty with 19 activities, categorized into 5 domains and an index score.
- Employed multinomial and logistic regression models to analyze the relationship between physical limitations and food security status.
Main Results:
- Older adults reporting 4 or more physical limitations were more likely to experience very low food security (aOR: 2.62).
- Key correlates of food insecurity included limitations in Instrumental Activities of Daily Living (aOR: 1.49), Leisure and Social Activities (aOR: 1.56), and General Physical Activities (aOR: 1.50).
- A significant association was found between multiple domains of physical limitations and increased odds of food insecurity.
Conclusions:
- Physical functioning is a crucial determinant of food security among older adults.
- Interventions should integrate assessments of physical functioning to identify at-risk individuals.
- Resources supporting food acquisition, preparation, and intake are essential for older adults with physical limitations.
