All of them were interviewed personally by a public health nurse using a structured questionnaire, and 1081 interviewed study subjects, including 468 men and 613 women, participated in physical examination, giving a participation rate of 68.8%.
In collaboration with Reporters Without Borders UK and other NGOs, we will feature regular case studies, interviewing the subjects where possible, and featuring some of their most powerful work.

When interviewing your subjects, draw on the research questions you studied in class.
This was tested during the pilot phase of an ongoing cohort study in Golestan by interviewing subjects twice and collecting urine samples twice, 2 months apart (Abnet et al, 2004).
Universities and hospitals will serve as study centers, enlisting and interviewing subjects, and collecting air, water, dust, and other environmental samples, as well as biological samples including blood, urine, hair, and fingernail clippings.
