A. During the initial phase of a cross-sectional study, a survey was conducted to determine the prevalence of existing disease in the community. Table 1 shows by age the population being surveyed and the number of detected cases of Diabetes Mellitus. Assume that this represents all persons aged 30-59 residing in the community. Table 1.

Answer Question #2
A. During the initial phase of a cross-sectional study, a survey was conducted to determine the
prevalence of existing disease in the community. Table 1 shows by age the population being surveyed
and the number of detected cases of Diabetes Mellitus. Assume that this represents all persons aged
30-59 residing in the community.

1.
Compute for the prevalence of DM by age group in Table 1.
2. Compute and interpret the following:
a. Prevalence ratio (40-49 years vs. 30-39 years; and 50-59 years vs. 30-39 years)
b. Prevalence difference (40-49 years vs. 30-39 years; and 50-59 years vs. 30-39 years)
3. Assume that 50% of all men and women aged 50-59 years decided that they did not want to
volunteer for this survey. Compute for the prevalence of DM by age group in table 2, assuming
that the occurrence of DM is the same in both those who did and did not participate.
