Malnutrition and nutrient intake values in the hungarian elderly
Department of Dietetics and Nutrition Sciences, Faculty of Health Sciences, Semmelweis University Budapest, Hungary
Head: prof. dr István Szabolcs
Summary
Introduction. Both obesity and malnutrition are health risks for the elderly, and deficiencies of certain vitamins and minerals also frequently occur.
Aim. The aim of this survey was to assess and analyse nutritional status, occurrence of malnutrition, and the nutrient intake of elderly persons over 55 years of age.
Material and method. Anthropometric data from 327 elderly persons were collected, and the Mini Nutritional Assessment (MNA) questionnaire was used to screen for malnutrition. Nutrient intake was assessed by 24-hour recall, and a nutrient calculator (NutriComp) was also used. The data were analysed using SPSS 15.0 software.
Results. According to MNA a quarter (25.07%) of participants were found to be either malnourished or to be at high risk of it, but ? interestingly ? only 3.98% of those had a subnormal BMI. On the other hand, a third of the subjects (31.19%) were obese (with BMI > 30 kg/m2). Total energy intake in both genders was lower than recommended (8943 kJ for men and 7493 for women versus 10450 kJ recommended). Fat energy and sodium intake were higher, while carbohydrate, calcium, vitamin D, C, folate and dietary fibre intake were lower than recommended. Overall daily fluid consumption, which is important for the elderly, fell below the desirable level.
Conclusions. In the Hungarian elderly, a relatively high risk of malnutrition and imbalance of nutrient intake (sodium excess and insufficiency of fluid, dietary fibre, calcium, vitamin D, and folate) was found and should be corrected.
INTRODUCTION
By 2050 the number of European citizens over 65 years of age is expected to rise by 70%, and the number of octogenarians by 170% ? a serious challenge for the Europe of the 21st century (1). In Hungary in 2009 the proportion of the population over 65 years old was 16.3% (2). Unfortunately, the life expectancy and healthy life span of this age group are lower than the European average.
In old age loss of lean body mass and increase of fat content occur, leading to a slowing down of the metabolism. Due to this and the more inactive lifestyle, there is a decrease in the energy requirement which ? with unchanged appetite ? results in body mass increase. On the other hand, malnutrition caused by poor appetite due to impaired taste and smell, or by difficulties with chewing and swallowing, is also frequent. In addition, disturbed nutrient absorption may lead to deficiencies of certain vitamins (D, B12) and minerals (calcium) (3).
Therefore, the assessment of dietary patterns and nutrient intake in the Hungarian elderly with the aim of proposing and introducing modern, balanced nutrition sustaining health and quality of life is a professional and social responsibility.
AIM
The aim of the survey was to assess and analyse nutritional status, occurrence and risk of malnutrition and obesity, and nutrient intake values for home-living or institutionalized Hungarian persons over 55 years of age, and to identify nutrition-related risks which could hinder ?successful aging?.
MATERIAL AND METHOD
The survey was carried out in 2008-2009 on 327 volunteers over 55 years old, living independently or in institutions of community care. Gender, living status, education and age subgroups are shown in table 1.
Personal and anthropometric data were obtained by a questionnaire containing both open and closed questions. To screen malnutrition, the Mini Nutritional
Assessment (MNA) developed for the elderly was used (4). Nutrient intake was examined by 24-hour recall plus the NutriComp nutrient calculator. Data processing and analyses were done using SPSS 15.0 statistical software.
RESULTS
25.07% of subjects were found to be malnourished or at high risk of malnutrition according to the Mini Nutritional Assessment questionnaire (see table 2). Note that malnutrition was more frequent in the institutionalized versus home-living elderly and in the capital of Hungary versus the countryside.

Based on the body mass index (BMI) (tab. 3 and 4) only 3.98% of participants were found to be malnourished
(BMI < 20 kg/m2), which reflects significant divergence from the MNA results. As MNA was developed to study the elderly age group, its results may be more appropriate to be taken into account. There was no gender-related difference in the BMI distribution but 31.19% of the investigated elderly subjects were found to be obese (BMI > 30 kg/m2),
which occurred more frequently in the age group of
65-75 years than in younger or more advanced age.
