Frailty syndrome (FS) is associated with the weakness of the physical and/or mental health of elderly people and it is becoming a global problem. The objective of the research study was to characterise elderly people attending Day Care Senior Centres, in terms of the  occurrence of frailty syndrome, dietary habits and nutritional risk. The survey was conducted among 49 individuals (21 men and 28  women) aged 61 – 97 (on average 77.5 ± 8.8) from Warsaw (24 people) and Rzeszów (25 people), who lived on their own, but attended Day  Care Senior Centres on a regular basis, where they were provided half board. A Cardiovascular Health Study Scale (CHS) was applied to  assess the frailty syndrome, while the nutritional risk was estimated on the basis of Dietary Screening Tool (DSC). The frailty syndrome  was diagnosed in 39.3 % of women and 9.5 % of men (26.5 % of the surveyed in total), the pre-frailty syndrome in 46.4 % of women and  52.4 % of men (49 % of the surveyed in total); 14.3 % of women and 38.1 % of men (24.5 % of the surveyed in total) did not show any  symptoms of FS. The differences between the men and women surveyed were significant. The nutritional risk was diagnosed in 63.3 % of  the people in the group surveyed, the probable nutritional risk – in 34.7 % and only 2 % of the surveyed did not show this symptom. No  correlation between the occurrence of FS and nutritional risk was found. Elderly people with FS less often consumed wholegrain bread and  yet more often sweets (tendency 0.1 > p > 0.05). Slightly less often their diet contained fatty cold cuts, vegetables, dairy products,  non-fried fish and more often lean cold cuts, fruits and dietary supplements (there was no statistical significance). Further prospective  cohort studies are needed to better understand the cause-effect relationships between the occurrence of frailty syndrome and malnutrition.
