Question

A cohort study following a group of 200 randomly selected adolescent females over 4 years finds the results shown in the table below Drops Out of High School Finishes High School Totals Pregnancy 36 24 60 No Pregnancy 56 84 140 Totals 92 108 200 Review the results provided in the table and answer the following question 1. Calculate the incidence rate (IR) for dropping out of high school. How do you interpret this result (in your own words)? 2. What is the attributable risk (AR) of dropping out of high school for adolescent females who become pregnant? How do ye interpret this result (in your own words)? 3. Calculate the relative risk (RR) of dropping out of high school for adolescent females who become pregnant. Assuming y RR is significant, how do you interpret this result (in your own words)?

Answer 1

1.Incidence rate is the ratio of the population with a particular disease to the total no of population.

Incidence rate of school dropouts with pregnancy:36/60 =0.6

Incidence rate of school dropouts without pregnancy:56/140=0.4

This means out of 60 students who are pregnant 36 of them dropped the school and Out of 140 students who are not pregnant 56 students dropped the school so the incidence rate of school dropout is higher in pregnant students as compared to nonpregnant students

2.Attributable risk is the difference between the risk of the exposed and unexposed group

Attributable risk of school dropouts in females who are pregnant is 36/60=0.6

56/140= 0.4

which is the difference of the no of pregnant female dropped out of school and no of pregnant females who finished the school so attributable risk is 0.6-0.4 =0.2

3.relative risk is the ratio of the exposed risk to unexposed risk .it is the relative of the risk pregnant dropout students to nonpregnant dropout students

36/60=0.6

56/140=0.4

Relative risk =0.6/0.2=3
