Background: There are few studies in the Czech Republic describing and evaluating the nutritional status of institutionalized elderly. Methods: Data were collected from 659 women and 156 men aged 65 years and older and living in retirement homes in and around Prague.
Data included: a Mini-Nutritional Assessment (MNA questionnaire), anthropometric measurements and biochemical evaluations. Results: According to the MNA questionnaire, 10.2% of these elderly individuals were malnourished and 39.4% were at risk of malnutrition.
More women than men were malnourished (OR = 0.59 and 95% CI 0.42-0.86). Mean BMI values were 25.5 for females and 27.5 for males.
MNA was positively correlated mostly with immobility (r = 0.63; p < 0.001), BMI (r = 0.57; p < 0.001) and mid-arm circumference (r = 0.56; p < 0.001). Serum albumin levels were < 28 g/l in 1.3% (1.3% of the women and 1.36% of the men) and between 29.0 - 34.0 g/l in 21% (22.5% of the women and 14.4% of the men).
Statistically significant differences between groups according to MNA scores were found for albumin, prealbumin, transferrin and creatinine. Prevalence of smoking was significantly higher among males.
Conclusion: The study results confirmed that institutionalized elderly, especially women, should be considered a nutritionally vulnerable population group that needs attention.
