Question

a group of researchers wants to determine whether certain dietary factors are associated with the risk of attention deficit hyperactivity disorder (adhd). the scientists follow a group of 500 healthy newborn babies for 10 years and collect health information as well as dietary practices for each child. at the end of the study period, the scientists analyze the data for correlations between the children's dietary practices and their likelihood of being diagnosed with adhd. this is an example of a study

Answer 1

The study is an example of a longitudinal study.

In a longitudinal study, researchers follow a group of people over a period of time and collect data at different points in time. This allows the researchers to see how changes in the participants' behavior or environment (in this case, their diet) may be associated with changes in their health outcomes (in this case, their risk of developing ADHD).

The data from this study could be used to support or refute the hypothesis that certain dietary factors are associated with the risk of ADHD. For example, if the data showed that children who ate a lot of sugary foods were more likely to be diagnosed with ADHD, this would support the hypothesis that diet plays a role in the development of ADHD. However, if the data showed no such association, this would suggest that diet is not a significant factor in the development of ADHD.
