This is a prospective study because the researchers are following a group of children over a period of time to observe the development of weight gain in relation to their eating behaviors and physical activity patterns. A retrospective study would involve looking back at past data to determine an association. In vitro studies involve testing on cells or tissues outside of a living organism, and a case-control study involves comparing a group with a particular outcome (e.g. weight gain) to a group without that outcome.
