Calculate the Relative Risk An uptick in attempted suicides

Calculate the Relative Risk: An uptick in attempted suicides in teen boys has interested the State Health authorities and they are looking for some information on the data the hospital has received in the past calendar year. The common exposure factor here is a history of parental abuse.

Suicide Attempt

No Suicide Attempt

History of Parental Abuse

No History of Parental Abuse

Those who reported parental abuse:

            14 had attempted suicide

            9 had not attempted suicide

Those who had not reported parental abuse:

            49 had attempted suicide

            149 had not attempted suicide

Calculate the Relative Risk

Solution

Relative Risk of Suicide Attempt with Parent abuse

=> [(number of suicide attempt in parental abuse)/(number of no suicide attempt in parental abuse)]/[(number of suicide attempt in no parental abuse)/(number of no suicide attempt in no parental abuse)]

=> [14/(14+9)]/[49/(49+149)]

=> 14/23 * 198/49

=> 2.459

Hence the relative risk is equal to 2.459
