Processes related to daily care of older adults during hospitalization, such as mobility and nutrition, have long-term consequences for their health and functioning. Although instrumental support provided by family members during hospitalization is highly prevalent, its relationship to older adults' actual walking and eating is unknown. Data on walking level (walking outside vs. inside the room) and nutritional intake were collected from 493 independent older adults admitted to internal medicine wards through up to three daily interviews using validated questionnaires.
