3,500 women between the ages 60 -74 years are in a town consisting of a population of 15,000 persons. 85 cases of cancer are in the town one year and 30 of these cases were women 60 -74 years old. What is the prevalence of cancer among women of this age group?
There are 15000 population of a town consisting of 3,500 women between ages 60-74 years.
Total cases of cancer in one year = 85.
Total cases of cancer for women for 60-74 years of age = 30.
Prevalance is basically a rate or is reffered to as prevalance rate is the proportion of persons in a population who have particular disease. It can be expressed in terms of percentage or it can be considered in terms of rate
For calculating the prevalance we have to calculate the probability of a person suffering from disease.
Therefore the prevalance of women of age group 60-74 for cancer is 0.008571. It can also be expressed in terms of percentage given by
Therefore the prevalance is that 0.85% of the population is affected or we can say that out of 15,000 persons , we have prevalnce as
It indicates that out of 15000 persons 128.5~129 women of age group 60-74 suffer from cancer
