RESUMO
OBJECTIVE: To investigate factors associated with the nutritional status in institutionalized Mexican older adults. MATERIAL AND METHODS: In this cross-sectional study of residents in three long-term care facilities (LTCFs) in Monterrey, Mexico, a medical history, Mini-Mental State Examination, Barthel index, and geriatric depression scale, and Mini Nutritional Assessment (MNA) were performed. Risk of malnutrition and malnutrition status were defined as MNA 17-23.5 and <17, respectively. RESULTS: Residents (n = 280) had a median age of 85 years and 72.1% were female. A total of 116 (41.4%) were at risk of malnutrition and 35 (12.5%) were malnourished. Having malnutrition or being at risk of malnutrition was associated with age (OR = 1.048), functional dependence (OR = 8.376), body mass index (BMI) <22 (OR = 7.518), cognitive impairment (OR = 2.210), urinary incontinence (OR = 2.397), previous stroke (OR = 2.870), Parkinson's disease (OR = 5.193), use of calcium channel blockers (OR = 3.706), and use of atypical antipsychotics (OR = 2.277). Having benign prostatic hyperplasia (OR = 0.067) or the use of angiotensin II receptor blockers (OR = 0.038) were related to being well-nourished. CONCLUSIONS: In a population of residents of three LTCFs in Mexico, we found a high prevalence of malnutrition or being at risk of malnutrition. This underscores the need to implement guidelines for the prompt identification of this condition and further explanation of the factors identified as possibly related to malnutrition.
