## Abstract

PROJECT SUMMARY
Nursing home residents, like Americans of all ages, suffer increasingly from obesity. Obesity develops
frequently in the presence of other chronic conditions, including cardiovascular diseases, diabetes, arthritis,
and some cancers. Compared to those with normal weight, residents with obesity experience more pain with
activity, and typically have more difficulty rising from a chair, walking, and maintaining balance. Thus, care
providers in nursing homes increasingly face the prospect of simultaneously managing multiple chronic
conditions and functional limitations among these residents. Using national Minimum Data Set (MDS) and
Medicare Provider Analysis and Review (MedPAR) files (2012-2015), this R03 project aims to 1) characterize
constellations of multimorbidity among nursing home residents with obesity. This will include: a) identifying the
most common 1, 2, 3, 4, 5, or 5 above concurrent conditions; and b) distinguishing patterns of constellations of
multimorbidity among residents with class I, class II and class III obesity, respectively. 2) assess the impact of
multimorbidity, found in A1, on death among nursing home residents with obesity. 3) assess the impact of
multimorbidity, found in A1, on hospitalization among nursing home residents with obesity. This study will
provide descriptive information of constellations of prevalent conditions among nursing home residents with
obesity, and identify subgroups of these individuals at high risk of preventable hospitalization and of mortality.
The study results will support clinicians with insight about how interventions to improve care can be targeted to
individuals in high-risk groups. This study addresses the Department of Health and Human Services' 2010
Strategic Framework on Multiple Chronic Conditions, which calls for studies to “understand the epidemiology of
multiple chronic conditions” (Goal 4, Objective B) and augment the currently limited research about “the
constellations of conditions that are most prevalent and most important …[and] to inform effective
interventions.”
