title: Relationship of nutritional status and oral health in elderly: Systematic review with meta-analysis.
abstract: This systematic review aimed to compare the nutritional status and oral health in older adults individuals. Three databases (Medline-Pubmed, Scopus and EMBASE) were searched up to October 28th 2016 for studies that performed the Subjective Global Assessment (SGA) or the Mini Nutritional Assessment (MNA) and an oral examination performed by a dental professional, either dental hygienist or a dentist. Both observational and interventional studies were screened for eligibility. Meta-analyses were performed comparing the malnourished/at risk of malnutrition and the normal nutrition subjects with three oral health parameters (edentulism, use of prosthesis and mean number of present teeth). Twenty-six studies were included in the systematic review, of which 23 were cross-sectional. It was showed that well-nourished subjects had a significantly higher number of pairs of teeth/Functional Teeth Units (FTU) in comparison to individuals with risk of malnutrition or malnutrition. The meta-analyses showed no statistically significant association between edentulism and use of prosthesis, as the pooled Relative Risk were, respectively, 1.072 (95% CI 0.957-1.200, p = 0.230) and 0.874 (95% CI 0.710-1.075, p = 0.202). On the other hand, the pooled Standard Mean Difference of mean number of present teeth were -0.141 (95% CI -0.278 to -0.005, p = 0.042) in subjects with at risk of malnutrition/malnourished. FTU and mean number of teeth present were significantly associated with nutritional status. Furthermore, more longitudinal studies in this field are needed.
