Relationship Between Diet Texture and Discharge Due to Deteriorating Health Condition in Nursing Home Residents in Japan

Abstract

We conducted a multicenter 1-year prospective study to evaluate the relationship between diet texture and discharge due to deteriorating health condition. The staff dietitian at each nursing home in Japan retrieved participants’ data (N = 9528) from nursing records. Diet texture was categorized into 4 groups: “normal,” “chopped,” “pureed,” and “parenteral nutrition.” Discharge status was categorized into 2 groups: “discharge due to deteriorating health condition” and “stable health condition.” Multivariate adjusted odds ratios and 95% confidence intervals (CIs) for “discharge due to deteriorating health condition” (n = 1820) were 1 (reference) for “normal”, 1.23 (95% CI = 1.05-1.45) for “chopped,” 1.82 (95% CI = 1.48-2.24) for “pureed,” and 1.82 (95% CI = 1.41-2.35) for “parenteral nutrition.” In conclusion, even after adjusting for baseline health status, texture-modified diets and parenteral nutrition were independently and positively associated with discharge due to deteriorating health condition.
