Final answer:
Having a family history, including a parent or sibling, does indeed increase the risk of developing diabetes due to genetic and environmental factors.
Step-by-step explanation:
The correct answer to whether having a parent or sibling increases the risk for diabetes is B) Yes, having a family history increases the risk. Diabetes, including both type 1 and type 2 diabetes, has a genetic component, meaning that having a family member with diabetes can indeed increase your likelihood of developing the condition.
This is due to the combination of genetic predisposition and, in the case of type 2 diabetes, environmental factors such as obesity, diet, and exercise that may be shared within a family.
Type 2 diabetes, which is more common, is strongly associated with lifestyle factors as well as genetics. Therefore, both genetic and environmental aspects must be taken into consideration when assessing the risk. It's not just siblings or parents that can influence risk; any first-degree relative with diabetes may increase the likelihood of developing the disease.
