In terms of blood pressure ranges, which group generally tends to have the broadest range for systolic pressures during childhood?

Systolic blood pressure tends to increase as children grow older, transitioning from newborns to school-aged children. The school-aged child group typically demonstrates a broader range for systolic pressures because of the physiological changes and growth that occur during early childhood.

In this age group, factors such as increased body size, activity level, and cardiovascular development contribute to the wider spectrum of acceptable systolic blood pressure values. The normal ranges for blood pressure during this phase are influenced by age, height, and individual health status, further extending the variability.

In comparison, newborns and infants usually have much narrower blood pressure ranges due to their smaller size and underdeveloped cardiovascular systems. As children progress through the toddler stage, their blood pressure also increases, but the variability remains less than what is observed in school-aged children where these factors are more pronounced and individual differences are greater. Thus, school-aged children indeed show the broadest range for systolic pressures during childhood.
