This condition is thought to be related to risk factors such as hypertension, diabetes mellitus, smoking, and lack of physical activity.

The level of closeness of the relationship with the contingency coefficient test in this study was obtained r = 0.239 (0.20-0.399) so it is said that the closeness of the relationship is weak. It can be concluded that there is a significant relationship between BMI and length of stay in SNH patients at Sultan Agung Islamic Hospital Semarang.
