The health and welfare of older people cannot be separated from the support system provided by the family. The family is very important in caring for elderly people living at home.

This research used a pre-experimental with one group pretest-posttest design using a purposive sampling technique with a total sample of 158 elderly people living with families, both nuclear families and extended families. The measuring instruments used in this research were a sphygmomanometer to measure the physical health of older people and the Mini-Mental State Exam (MMSE) for the mental health of the elderly, which was then analyzed using the paired t-test. The results of the study showed that the physical health of older people, the mean (SD) value for pre-post systolic blood pressure was 158.1 (14,461) - 144.56 (11,816), and for pre-post diastolic blood pressure was 86.77 (4,824) - 77.41 (5,884), while mental health elderly people obtained pre-post results of 20.08 (1.963) – 24.24 (1.982), with different test results obtained a p-value of 0.0001.
