The study aimed to determine the degree of satisfaction with health, psychological, environmental, and social needs and to determine the effects of a nutritional intervention, physical activity, and comprehensive activity (nutritional intervention plus physical activity) on the degree of satisfaction of the needs of older people with frailty syndrome (FS). The study included 188 residents (140 women and 48 men) and was conducted using the Fried scale and Camberwell’s modified brief needs assessment. In addition, data were collected on age, sex, educational level, type of the previous occupation, marital status, remaining in a relationship, co-residents, place of residence, work status, financial situation, and help with housework. Intervention groups were formed: G1-diet, G2-physical activity, G3-comprehensive therapy, and G4-control. Stage 1 (T1)-3 months after the first examination, stage 2 (T2)-after another three months, the measurements from stage 0. In all groups, the majority were women, respondents with a low or medium level of education in relationships. The degree of need satisfaction in groups G2, G3, and G4 depended on the measurement time (p = 0.019, p = 0.007, p = 0.016). The introduction of physical activity and physical activity in combination with dietary changes most effectively influenced the increase in the level of need satisfaction in elderly patients with frailty.
