Prevalence of food insecurity based on presence or absence of probable sarcopenia for each definition: Definition 1 – SDOC defined grip strength <35.5kg for men and <20kg for women, Definition 2 – SDOC defined grip strength divided by BMI <1.05 for men and <0.79 for women, Definition 3 - SDOC defined grip strength divided by weight <0.45 for men and <0.34 for women, Definition 4 – FNIH defined grip strength <26kg for men and <16kg for women.
