The aim of this systematic review was to examine the association between malnutrition and oral health in older people (≥ 60 years of age). A comprehensive systematic literature search was performed in four databases (PubMed, CINAHL, Dentistry and Oral Sciences Source, and Embase) for literature from January 2000 to May 2020. Both observational and intervention studies were screened for eligibility. Two reviewers independently screened the search results to identify potential eligible studies, and assessed the methodological quality of the full-text studies. A total of 3240 potential studies were identified. After judgement for relevance, 10 studies (cross-sectional (n = 9), prospective cohort (n = 1)) met the inclusion criteria. Three studies described malnourished participants as having fewer teeth, or functional (tooth) units (FTUs), compared to well-nourished participants. Four studies reported soft tissue problems in malnourished participants, including red tongue with blisters, and dry or cracked lips. Subjective oral health was the topic in six studies, with poorer oral health and negative self-perception of oral health in malnourished elderly participants. There are associations between (at risk of) malnutrition and oral health in older people, categorized in hard and soft tissue conditions of the mouth, and subjective oral health. Future research should be focused on longitudinal cohort studies with proper determination of malnutrition and oral health assessments, in order to evaluate the actual association between malnutrition and oral health in older people.
This study evaluates the concurrent validity of five malnutrition screening tools to identify older hospitalized patients against the Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria as limited evidence is available. The screening tools Short Nutritional Assessment Questionnaire (SNAQ), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST), Mini Nutritional Assessment—Short Form (MNA-SF), and the Patient-Generated Subjective Global Assessment—Short Form (PG-SGA-SF) with cut-offs for both malnutrition (conservative) and moderate malnutrition or risk of malnutrition (liberal) were used. The concurrent validity was determined by the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the level of agreement by Cohen’s kappa. In total, 356 patients were included in the analyses (median age 70 y (IQR 63–77); 54% male). The prevalence of malnutrition according to the GLIM criteria without prior screening was 42%. The conservative cut-offs showed a low-to-moderate sensitivity (32–68%) and moderate-to-high specificity (61–98%). The PPV and NPV ranged from 59 to 94% and 67–86%, respectively. The Cohen’s kappa showed poor agreement (k = 0.21–0.59). The liberal cut-offs displayed a moderate-to-high sensitivity (66–89%) and a low-to-high specificity (46–95%). The agreement was fair to good (k = 0.33–0.75). The currently used screening tools vary in their capacity to identify hospitalized older patients with malnutrition. The screening process in the GLIM framework requires further consideration.
Rationale: In this study, we aimed to explore how dietitians’ history-taking questions function during dietary counseling of clients with malnutrition (risk). Fruitful functioning of history-taking questions during the problem identification phase is crucial for dietitians to develop a client-centered dietary treatment plan.Methods: Using discursive psychology, we analyzed the problem identification phase of recorded dietitian-client conversations of 7 dietitians and 17 clients. Discursive psychology is a qualitative, inductive methodology that is used to analyze real-life conversations. Discursive psychology focuses on how descriptions in talk (including wording, intonation, pauses, non-verbal behavior) accomplish actions such as presenting oneself in a particular way.Results: Our analysis shows how, in response to dietitians’ history-taking questions, clients repeatedly demonstrate that they have already made some effort to self-help. Typically, these history-taking questions presume some biopsychosocial factor as the cause of the dietary problems discussed. In response, clients show they already started to eat extra, closely monitored their body weight, and tried to eat despite having no appetite. In addition, clients account for the absence of efforts by claiming various kinds of inability, such as facing difficulties in preparing food for oneself or by questioning whether their underlying medical condition caused the diet-related problem in the first place.Conclusion: This study shows that history-taking questions not only elicit answers with factual information but also evoke clients’ self-presentations. Responses from dietitians show little attention to the relevance of these self-presentations,while clients treat self-help as a normative requirement to demonstrate they have done everything they can before they sought professional help. To optimize the problem identification phase, we suggest that in addition to conversationaltechniques dietitians could increase their attention to clients’ actions performed.
