There was a 5-year study of asthma among children in the state of Rhode Island. Children were followed and assessed for new asthma cases every year. At the beginning of the study, 17 of the 2,400 children already had asthma. At the first yearly assessment, 15 more kids had developed asthma. At the second yearly assessment, 20 more kids had developed asthma. At the third assessment, 34 more kids, at the fourth assessment, 25 more kids, and at the final and fifth assessment, 15 more kids had developed asthma.

Answer :

To understand the progression of asthma among children in this study, we can look at each year's developments and how the new cases add to the initial count of asthma cases.

Initial Situation:

  • At the beginning of the study, 17 out of 2,400 children already had asthma.

Yearly Assessments:

  1. First Year: 15 more children developed asthma.

    • Total cases: 17 (initial) + 15 (new) = 32
  2. Second Year: 20 more children developed asthma.

    • Total cases: 32 (previous total) + 20 (new cases) = 52
  3. Third Year: 34 more children developed asthma.

    • Total cases: 52 (previous total) + 34 (new cases) = 86
  4. Fourth Year: 25 more children developed asthma.

    • Total cases: 86 (previous total) + 25 (new cases) = 111
  5. Fifth Year: 15 more children developed asthma.

    • Total cases: 111 (previous total) + 15 (new cases) = 126

Conclusion:

  • By the end of the 5-year study, a total of 126 children out of the initial 2,400 had developed asthma.

Understanding the Study:

  • Who: Children in Rhode Island
  • What: Study on the development of asthma
  • When: Conducted over 5 years
  • Where: The state of Rhode Island
  • How: Followed and assessed for new asthma cases yearly

This study can help understand trends in asthma development in children, potentially guiding public health initiatives and further research on environmental or genetic factors contributing to asthma.
