First graders who misbehave in school may be more likely to be regular smokers as young adults according to a new study presented in the July 2004 issue of the American Journal of Epidemiology. After following a group of U.S. first graders for 15 years, it was found that among those kids who had tried smoking and misbehaved, 73% were daily smokers

This problem is incomplete.

To understand the study and its findings, we need to break it down into several components:

1. The Study: The study mentioned is published in the July 2004 issue of the American Journal of Epidemiology. It follows a group of U.S. first graders for a period of 15 years.

2. Participants: The participants of the study were first graders, meaning they were approximately six years old at the beginning of the study.

3. Misbehavior in School: The study focuses on first graders who exhibited misbehavior in school. It does not specify the types of misbehavior, but it suggests that these behaviors could be indicators of certain traits or tendencies.

4. Smoking Behavior: The study examines the smoking behavior of the participants as they transition into young adulthood. It specifically looks at whether these individuals have tried smoking and whether they have become daily smokers.

5. Study Findings: The study found that among the group of first graders who had both tried smoking and exhibited misbehavior, 73% became daily smokers as young adults.

It's important to note that the study suggests an association between misbehavior in first grade and an increased likelihood of becoming a regular smoker as a young adult. However, correlation does not imply causation. There may be various factors that contribute to this association, which the study does not necessarily account for.

The study is based on observation and data gathered over a significant period of time from a specific group of participants. Therefore, it is essential to consider the limitations and potential biases of the study when interpreting its findings.
