The study was conducted in a probabilistic sample of 1,786 subjects aged ≥ 60 years. The dependent variable was disability defined as mild (some difficulty) or severe (total dependence) in performing at least one basic activity of daily living.

Self-reported hypertension and arthritis were associated with mild disability, while diabetes and stroke were associated with severe disability.

According to the results, chronic conditions associated with disability in the study population are preventable, and severely disabled elderly had less extra-family social
