Malnutrition increases frailty among older adults: How? Dear Editor, We read the article by Boulos et al. [1], aiming to show the relationship between frailty and malnutrition among older adults living in a rural setting, with great interest. In this well designed and written study, the authors showed that malnutrition rate was higher in the participants with frailty than without and malnutrition was found to be an independently correlate for being frail. When analyzing this hypothesis, it would be more appropriate to select the participants in each group to be similar among the age, gender and other baseline characteristics those might also have an affect on the prevalence of malnutrition. In recent study, frail individuals were older than pre-frail and robust individuals and gender rates in each group were different. We know that the prevalence of malnutrition increases with aging [2] and some evidence from observational studies show that female genders are more prone to be in malnutrition status than men [3]. The recent study by Boulos et al. demonstrated that frail individuals had greater malnutrition rate and malnutrition was associated with increased frailty rate. At the same time, frail subjects were older and had higher female rate than other ones. In light of mentioned factors, we think that the results of the study should be supported with further studies investigating the same hypothesis with the population that have the similar baseline characteristics according to the frailty status to find out the exact relationships between frailty and malnutrition.
