INTRODUCTION: It is important to assess longitudinal nutritional parameters during the ageing process in order to determine body composition changes. This procedure is more relevant when dealing with institutionalised geriatric @entity1 suffering from @entity73 . The aim of this study was to assess the interactions, if any, between mental status and several nutritional parameters in a cohort of elderly @entity1 . MATERIAL AND METHODS: A longitudinal prospective two years follow-up evaluation was performed on 301 elderly residents (233 females and 68 males) in a nursing home, of whom 51 of them fulfilled the clinical criteria for @entity303 . Both anthropometric and biochemical parameters were obtained annually, according to standard procedures. RESULTS: The @entity303 group had lower values when compared to the non- @entity303 group. Furthermore, nutritional values remained constant in the group with @entity73 (no significant differences were observed throughout the study period). BMI 24.5  4.9 vs 24.2  4.1; tricipital skinfold 15.0  6.0 vs 14.7  6.9; brachial circumference 25.9  3.3 vs 25.7  3.5, and albumin 3.7  0.3 vs 3.7  0.3. At the end of the study, the group without @entity73 showed lower values in all the parameters analysed when compared to the baseline ones, except for bicipital fold and plasma @entity1674 . CONCLUSIONS: Our study shows that there are no variations in the elderly with @entity73 , as regards the nutritional, anthropometric and biochemist parameters analysed. On the contrary, the group with normal cognitive status showed a reduction in most of the parameters. Further studies analysing larger populations of elderly @entity1 and over longer periods of time will provide more information to improve our knowledge on this important issue.
