OBJECTIVES: Determine which behavioral syndromes of dementia are independently related to weight loss. DESIGN: Longitudinal study using four subsequent quarterly Minimum Data Set (MDS) 2.0 assessments. Characteristics obtained in one period were related to weight loss observed in the next period. SETTING: Eight nursing homes in the Netherlands. PARTICIPANTS: The initial population was 2031 nursing home residents with four quarterly MDS assessments within a period of 15 months. We selected 1850 subjects who were at least 65 years old at the time of the first assessment and who were not comatose. MEASUREMENTS: Information about the presence of four behavioral syndromes (depression, apathy, agitation, and rejection of care), demographic data, cognition status, body mass index (BMI), and time that residents were involved in activities were obtained from MDS 2.0. RESULTS: Bivariate correlation showed that weight loss at follow-up assessments was related to all baseline behavioral syndromes, degree of cognitive impairment, body mass index, and time that residents were involved in activities. Multivariable binary logistic regression with these factors showed that the only behavioral syndrome that was independently related to subsequent weight loss was apathy. In multivariable analysis, the degree of cognitive impairment and BMI were also independently related to weight loss. CONCLUSION: These results suggest that of all behavioral factors we have assessed, apathy had the strongest association with weight loss in nursing home residents even when adjusted for the degree of cognitive impairment.
