What health condition has become more prevalent in children since the 1990s due to inactivity and poor nutrition?

The increase in diabetes among children since the 1990s is closely linked to rising levels of inactivity and poor nutrition. This health condition, particularly type 2 diabetes, has seen a significant rise in prevalence due to lifestyle factors such as sedentary behavior and diets high in sugars and processed foods. These lifestyle choices have contributed to increased rates of obesity in children, which is a major risk factor for developing type 2 diabetes. Unlike other options, which may not have the same direct correlation with lifestyle changes over the past few decades, the link between rising obesity rates and diabetes highlights the importance of addressing nutrition and physical activity in promoting children's health.
