Abstract

Background- Both obesity and malnutrition are common health problems in older adults. Aim- The aim of our study is to investigate the prevalence of undernutrition and related factors in older obese patients. Methods- 1911 older outpatients who underwent comprehensive geriatric assessment were included in this cross-sectional study. Body mass index (BMI) was categorized as follows: ‘Underweight’ = BMI < 18.5, ‘Normal weight’ = 18.5 ≤ BMI < 25, ‘Overweight’ 25 ≤ BMI < 30, and ‘Obesity’ ≥ BMI 30. Mini-Nutritional Assessment scores > 23.5, 17–23.5, or < 17 were categorized as well-nourished, malnutrition risk, and malnutrition, respectively. Those who were not well-nourished were considered undernutrition. Results- Of 1911 patients, with a mean age of 77.34 ± 8.0 years, 931 (48.7%) were obese. Of whom 6.0% were malnourished and 26.3% were at risk of malnutrition. Age, females, widowed and those living with their children, the number of drugs used, and the presence of heart failure, Parkinson’s disease, and dementia, decreased calf circumference and muscle strength were higher in obese patients with undernutrition than obese well-nourished patients (p < 0.05). After adjustment for the aforementioned factors, basic and instrumental activities of daily livings, and Tinetti scores were lower, and falls and Geriatric Depression Scale-15 scores were higher in those with undernutrition compared to those with well-nourished among older obese patients (p < 0.05). Conclusions- Half of the older patients were obese and undernutrition was observed in one out of every three older obese patients. Undernutrition was associated with decreased functional capacity, impairment in balance and gait functions, falls, and depressed mood. Therefore, we recommend to screen older obese patients for nutritional status.
