LUGO GONZALEZ, Isaías Vicente  y  SANCHEZ CERVANTES, Cintia Tamara. Pica behavior in patients with chronic end-stage kidney disease: Behavioral, psychosocial and clinical variables associated. Rev. Mex. de trastor. aliment [online]. 2019, vol.10, n.2, pp.207-217.  Epub 14-Mar-2022. ISSN 2007-1523.

Pica behavior (PB) is defined as the persistent intake of non-nutritive substances, which has been identified in various chronic diseases. The aim of this study was to estimate the presence of PB among patients with chronic end-stage kidney disease (CESKD), to identify the main substances ingested, as well as associated behavioral, psychosocial and clinical variables. A total of 100 adult patients (M age = 43.9, SD = 15.8), men and women, under hemodialysis, completed an evaluation that included questions on the functional analysis of behavior. Of the total participants, 58% presented PB. The main food substances ingested were: ice (37%), grains of sugar or salt (11%), and wheat flour (10%); of the non-food substances highlighted: stones or partition (7%), bicarbonate or magnesia (6%), and mud (5%). The main situations associated with PB were inactivity (27%) and anxiety (10%); as consequences highlighted the feeling of well-being (36%) and decreased anxiety (10%). Patients with PB were characterized by their lower age and perception of social support, as well as greater anxiety. The results of this study support the development of specific forms of intervention for the management of PB in patients with CESKD.
