1. Review the WEB pages on EPIINFO and work through a sample problem
You've ben hired by the Massachusett's Attorney Geberal's office to consult in their upcoming suit against the tobacco companies regarding retrieval of the public health costs of smoking. As part of the discovery process, you are asked to assist in the survey and analysis of secular trends in smoking behaviors. Data are from a health maintenance organization(HMO) in New Bedford, Massachusetts. This institution collected repeated measurements of its membership's smoking patterns. Available to you are pairs of repeated measurements, 1980 and 1995, of smoking history information for n=10 members. Completed surveys are given below. Notice that the HMO forgot to include in their survey instrument the following items: date of birth, date of survey, age, sex. Identifying information, in the form of a medical record number, is coded in the 12 column grid the upper right corner. This block is labelled "Project use only. Do not fill in".
Surveys: #1, #2, #3, #4, #5, #6, #7, #8, #9, #10
Exercise:Prepare a report that documents your solutions to the following:
1. Using Epi-Info, design and create a data entry program called smoke.qes. Take care that you need to accommodate the missing fields( id, date of birth, date of survey, age, sex). Include a copy of the data entry program in an appendix to your report.2. Develop a coding manual, and include it in an appendix to your report.
3. Using Epi-Info, develop a set of within form checks called smoke.chk. Include a copy of the check program in an appendix to your report.
4. Enter your data into Epi-Info and save in a file called smoke.rec. Include a copy in the appendix to your report.
5. Verify the data.
6. Export smoke.rec to a SAS data set called smoke.sd2.
7. Write a simple descriptive report that summarizes each variable. Include a list of the data in your report as the last table. Put the contents of the data set in an appendix. Place your report on your WEB page. Print a paper copy of the report (not the appendix) to turn in.
