Final answer:
According to the CDC's worst-case scenario in 2010, up to 30% of the US adult population could have diabetes by 2050, influenced by the increasing rates of obesity and pre-diabetes.
Step-by-step explanation:
According to the Centers for Disease Control and Prevention's (CDC) worst-case projection made in 2010, by the year 2050, it is estimated that up to 30% of the US adult population could have diabetes. This projection takes into account the increasing rates of obesity and pre-diabetes, which are strong risk factors for the development of type 2 diabetes. Furthermore, currently about 30 million Americans have type 2 diabetes and another 90 million have pre-diabetes, conditions that have significant long-term complications such as loss of eyesight, heart disease, and kidney failure. Prevention measures include maintaining a healthy diet, regular physical activity, and a normal body weight to reduce the risk of diabetes.
