Abstract
BackgroundFew data are available on the nutritional status of Iranian geriatric population. The present study aimed to determine the nutritional status of older adults’ population in Birjand, East of Iran.MethodsThe community-based cohort study was performed on older adults population (60 years and older) living in urban and rural areas of Birjand. The mini nutritional assessment (MNA) questionnaire was used to assess nutritional status. Anthropometric and biochemical evaluation were also performed for all of the participants.ResultsA total of 1417 geriatric person were enrolled in this study, which, most of them were female (51.9 %). According to MNA tool, most of the participants (73.3 %) had normal nutrition (MNA score ≥ 24). Malnourished (MNA score < 17) and at high risk of malnutrition (MNA score: 17- 23.5) were constituted 0.9 % and 25.8 % of the participants, respectively. Marital status, occupation, period of education and family member were associated with nutritional status. Multiple logistic regression showed that with increase of body mass index (BMI) (OR = 0.96), education years (OR = 0.95), hemoglobin (OR = 0.86) and lymphocyte (OR = 0.98), the odds of malnutrition decreased, but with increase of age the odds (1.03) of malnutrition is also elevated.ConclusionsMNA could successfully forecast the risk of malnutrition and malnourished people. Sociodemographic factors are associated with the nutritional status.

Summary
Few data are available on the nutritional status of Iranian geriatric population. The present study aimed to determine the nutritional status of older adults’ population in Birjand, East of Iran. Due to the development of health services and rising life expectancy, the mean age of the population in different countries has increased [1, 2]. In some countries, such as Japan, a large part of the country’s population is older adults [3]. Aging causes significant changes in various organs of the body, especially the gastrointestinal tract. These changes include decreased salivation, difficulty swallowing, gastrointestinal upset, and constipation that affect food intake. Some social factors such as loneliness, dementia and depression reduce food intake [9]
