Objective: Diabetes is a chronic disease that has connotations of culture or unhealthy lifestyle, so to overcome this a cultural approach is needed that leads to better behavioral patterns. The purpose of this study was to determine the effect of Sudanese culture sensitive family nursing model on improving family behavior in controlling blood sugar in elderly with diabetes

Method: This study used quasi-experimental design pre and post-test involving 114 respondents of families with elderly diabetes consisting of 57 respondents in the intervention group and 57 respondents in the control group. Samples were taken by multistage cluster sampling and statistical analysis using univariate, bivariate with independent t-test and chi-square, multivariate with General Linear Model Repeated Measure (GLM-RM).

Result: The results showed an increase in the mean of  family behavior (knowledge, attitudes, and actions) and a decrease in the mean of blood sugar levels at three months and six months after the intervention model in the intervention group compared to the control group with each p-value = 0.001

Conclusions: Sundanese culture sensitive family nursing models can improve family behavior in treating the elderly with diabetes and have an impact on controlling blood sugar. It is recommended that this Sundanesse culture sensitive family nursing model be used as a pattern of a culture based approach in the treatment of elderly with diabetes.
