title: Nutritional status is altered in the self-neglecting elderly.
abstract: Elder self-neglect is the most common form of elder mistreatment. Individuals who cannot provide basic needs for themselves may develop social, functional, and physical deficits. The systematic characterization of self-neglecting individuals is the goal of the Consortium for Research in Elder Self-Neglect of Texas project. This study reports on the nutritional status of self-neglecting elderly. Self-neglectors (SN) were recruited based on referrals along with matched control (CN) subjects. Data are for 40 SN subjects (age 76 +/- 7 y) and 40 CN subjects (76 +/- 7 y). Blood samples were collected and analyzed for indices of nutritional status. SN subjects had a greater serum concentration of total homocysteine than CN subjects (13.6 +/- 4.5 vs. 11.6 +/- 5.6 micromol/L, P < 0.05) and a lower concentration of red blood cell folate (1380 +/- 514 vs. 1792 +/- 793 nmol/L, P < 0.05). Plasma beta-carotene and alpha-tocopherol were lower in SN subjects (0.28 +/- 0.2 vs. 0.43 +/- 0.33 micromol/L; 23.2 +/- 9.3 vs. 27.8 +/- 9.3 micromol/L, P < 0.05). SN subjects had a lower serum concentration of 25-hydroxyvitamin D than CN subjects (33.7 +/- 16.4 vs. 44.1 +/- 19.6 nmol/L, P < 0.05). These differences in markers of nutritional status show that the self-neglecting elderly are at risk for altered nutritional status, particularly of folate, antioxidants, and vitamin D. Evaluation of these data in relation to other functional and cognitive assessments are critical for evaluating the relation between nutrition and self-neglect.
