Relationship of Frailty, Nutritional Status and Oral Health-Related Quality of Life in Mexico City Nursing Home Residents

We aimed to identify the association among nutritional status, Oral Health-Related Quality of Life (OHRQoL) and frailty, and to estimate the mediation effect of these conditions between age and frailty in a group of Mexico City nursing home residents.
