Ageing populations entail important social issues. The population of Lodz is characterised by the highest ageing ratio in Poland (17.2% people aged 65 or above). The aim of our study was to present factors determining the use of social support services in the subpopulation of elderly people in a city environment. The study, conducted between 2011 and 2012 with the use of a survey questionnaire, included 466 respondents aged 65 or older, who were looked after by the Municipal Social Welfare Centre, Lodz-Polesie. The response rate was 93.2%. Most beneficiaries were women (77.9%). The respondents were mostly widows (73.9% of women) or widowers (43.7% of men). Most respondents applied for nursing services (79.7%), while 28.3% asked for financial help. In Lodz as a whole, these percentages were 81.0% and 19.0%. A chronic disease was the most common cause of the application for help (73.4%). In 4.1% of applicants, the cause was a low income per capita. Multivariate logistic regression analysis indicated that the variables which contributed to receiving financial support included being a man, aged 65-69 years, being single and receiving a monthly salary per capita below 500.0 PLN (Polish New Zlotys). The variables which contributed to receiving social care service in the form of nursing services included being a woman, aged 85 years or older, receiving a monthly salary per capita between 1001.0 and 1500.0 PLN, suffering from a chronic disease, which was a reason for applying for social support service, a result on the Activities of Daily Living scale confirming disability and a very negative self-evaluation of health. The results of the study have shown that the poor health condition of elderly people is the most frequent reason for applying for social services. Identifying reasons for applying for social care by elderly people might facilitate the introduction of workable solutions in the social and healthcare policy.
