Quizplus · Accepted Answer

This is a prospective study because the scientists are following the children over a period of time to observe and record their behaviors and determine if there is an association with weight gain. A case-control study involves comparing individuals with a certain condition to those without it, and a retrospective study involves looking back at past events or data rather than following individuals over time. In vitro studies are conducted in a laboratory setting using isolated cells or tissues rather than living organisms.
