Objective: To compare the social support network and expectation of care among elderly persons who live alone and those who live with others. Method: A cross-sectional study with 348 elderly people living in the community in the municipal region of Várzea Grande, Mato Grosso, Brazil was performed. The elderly were interviewed using a questionnaire composed of socio-demographic issues; evaluation tools of basic and instrumental activities of daily living; and care expectation and perceived social support network. The data were submitted to descriptive and comparative statistical analysis, the chi-squared test or Fisher’s exact test at a significance level of 5%. Results: Most of the interviewees were younger elderly women. Of these,14.66% lived alone and 85.34% lived with other people, with mainly bi-generation family arrangements. The majority stated that they had fair health, had up to two diseases, were dependent in instrumental activities of daily living and independent in self-care activities. Elderly persons who lived with others relied on their family, and the expectation of care was aimed at a daughter or daughter-in-law; while those who lived alone expected to rely on neighbors or friends to help with their tasks, if needed. Conclusion: Family members are the greatest providers of support and care, and the elderly hope to count on them when they need help in carrying out basic and instrumental activities of daily living.
