Final answer:
Sodium intake in children and adolescence varies depending on factors such as diet and food choices. School-age children generally have higher sodium intake, not specifically females. Sodium intake has a positive relationship with potassium intake. There is a link between energy intake and sodium intake as many high-sodium foods are also high in calories.
Step-by-step explanation:
The sodium intake of children and adolescence varies depending on various factors. A) After introducing solid foods, sodium intake typically increases, but it doesn't necessarily dramatically increase, as it depends on the individual's diet and food choices. B) School-age children (6 - 11 years old) do have higher sodium intake compared to other age groups, however, it is not specifically higher in females. C) There is a positive relationship between sodium and potassium intake, meaning that as sodium intake increases, so does potassium intake. D) There is a link between energy (kcal) intake and sodium intake, as many processed and manufactured foods, which tend to be high in sodium, are often high in calories as well.
