Aim. The main aim of the research is to examine the impact of public health interventions on the frailty and loneliness of the elderly. The specific objectives are: a) Quantify the aging parameters; b) Determine the connection between the frailty and independent living; c) Determine the connection between loneliness and quality of life. Respondents and methods. The study included 410 participants, aged +75, living in their own homes, 283 women and 127 men. Elderly persons resident in the western part of the city of Rijeka were included in the intervention groups, and the control group consisted of the elderly resident in the eastern part of the city of Rijeka. Participants of the intervention groups “prevention of falls” and "reduction of loneliness" and the control group were monitored through the programs "integrated care" and "regular care". In this study were used validated questionnaires for frailty (TFI), loneliness (JGLS-6); independent living (ADL, IADL) and quality of life (SF-36; SF-12v2). Results. After one year, the overall level of frailty and loneliness increased significantly in the “regular care” program, while in “integrated care” program did not increase. Higher number of subjects in the household and higher total psychological quality of life is associated with lower frailty while greater frailty is associated with the use of the “doctor visit” service. Decreased level of loneliness is associated with higher total psychological quality of life. Variables that predict loneliness are alcohol consumption and both aspects of limiting independent living. Conclusion. Integrated care has positive effects on frailty and loneliness and indicates that urban service interventions are an inevitable solution in future policies and strategies for older people. The social ecological model of healthy aging can be adapted to the sustainable development goals.
