Food Insecurity Associated with Self-Reported Falls Among Medicare Advantage Members

More than 3 million older US adults injure themselves by falling each year. Falls are a major cause of morbidity and mortality for this population, and account for nearly $30 billion in Medicare expenditures annually. Falls have been linked to frailty and vitamin D deficiency, both of which are linked to low nutrient intake and food insecurity. This retrospective, observational study is the first the authors know of to directly assess the relationship between food insecurity and falls. The study sample consisted of 26,525 Medicare Advantage members at Kaiser Permanente Northwest, a group model health maintenance organization, who had completed a quality of care survey between April 2013 and March 2017 and who maintained continuous enrollment in the 12 months prior to the survey date. Multivariable logistic regression analysis was used to assess the association between self-reported food insecurity and falls; electronic health record variables for age, sex, socioeconomic status, comorbidity, and health care utilization were included as covariates. Medicare Advantage members who reported food insecurity had 1.69 times higher odds of experiencing a fall in the past year than those without food insecurity, in adjusted analysis. Age, sex, comorbidity, and health care utilization also were significantly associated with falls. Food insecurity is significantly associated with falls among Medicare Advantage members. Routine assessment for food insecurity within the health care system, with subsequent referral to food resources, may help reduce rates of falls in older populations.
