This study aimed to identify the health behavioral needs of older adults based on the Omaha System. This descriptive study was conducted in Northern Cyprus between May and October 2021. The sample comprised 400 older adults who resided in the Gecitkale municipality. The problem-classification scheme of the Omaha system was used for data collection. The main behavioral health problems concerned nutrition (100%), physical activity (87.25%), and medication regimen (87.25%). In addition, all behavioral health problems defined by the Omaha system were evident in participants who were 75 years and older, female, single, childless, educated, and with incomes that did not cover expenses ( p < .05). This study identified the basic healthcare needs of older adults, which increased in parallel with age. The Omaha system may help health professionals deliver services focusing on older people’s needs.
