Bishop NJ, et al. - Considering the observation that both food insecurity and comorbidity are precursors to functional limitation in older adults, researchers investigated if food insecurity modifies the progression from chronic disease to disability via examining 5986 respondents age 50 and older drawn from the 2012–2014 Health and Retirement Study (HRS) and 2013 Health Care and Nutrition Study (HCNS). Findings revealed the association of food insecurity with a greater number of mobility limitations and more rapid increase in mobility limitations over the two-year observational period. In addition, food security status modified the association between comorbidity and both mobility limitation outcomes, with the food secure exhibiting a stronger positive association between chronic conditions and mobility limitations than the food insecure. More mobility limitations were noted in the food insecure vs the food secure when few chronic conditions were reported.
