Instructions

The purpose of this form is to provide an exact and common format for the Core Data from the population surveys for transfer to the MONICA Data Centre (MDC). The data should be sent on magnetic tapes, not on paper forms. Instructions for data transfer on magnetic tapes are given in Part V, Section 1 : Data Transfer to the MONICA Data Centre. To avoid errors, special attention should be paid to extracting the data required for this form from the local data set.

Version 7 of the Data Transfer Format has the following changes to Version 6:

Data from the second MONICA survey can be transferred to the MDC by either using Version 6 or Version 7 of the Data Transfer Format. Every MCC should transfer data from the Third MONICA Survey using Version 7.

General instructions

The ITEM NAME on the form is a computer variable name used for the item by the MDC.

The COLUMNS indicate the columns on which the value of the item is to appear in the record on the magnetic tape. Data for different subjects must be written on different records.

Blank fields are not allowed in the magnetic tape record.

Instructions for making corrections to data that have already been sent to the MDC are given in Part V, Section 3.3.

Please contact the MDC for instructions if you cannot provide information as specified in this document.

Specific instructions for each item

These instructions should be followed carefully when creating a computer file for transfer to the MDC. Please ensure that the instructions are for the version of the Core Data Transfer Format being used. Specific instructions are listed by item below:

Enter number 04 to indicate the CORE DATA TRANSFER FORMAT-SURVEY DATA.

Item 2

2 VERSN Form version |_7| 3

Enter the version number printed on the form. If the number is not 7 these instructions do not correspond to the form you are using. Check that you are using the valid version of the form.

Item 3

3 CENTRE MONICA Collaborating Centre |__|__| 4 to 5

Enter the official MONICA Collaborating Centre Code number as it appears in Part I, Appendix 2: MONICA Collaborating Centres and Reporting Units. If your centre is not listed or is erroneously listed in this appendix, contact the MDC for instructions.

Item 4

4 RUNIT MONICA Reporting Unit |__|__| 6 to 7

Enter the official MONICA Reporting Unit code number as it appears in Part I, Appendix 2. Even if your centre has only one reporting unit please enter the appropriate code number here. Do not leave blanks in this item.

Item 5

5 SERIAL Serial number |__|__|__|__|__|__| 8 to 13

Enter here the serial number of the subject for whom the form is being completed. This number consists of six digits. Each serial number issued must be unique within each MONICA Reporting Unit and within each of the two or three surveys. Different MONICA Reporting Units and different surveys may use the same serial numbers. Check that the serial number you enter is correct.

Item 6

6 NUMSUR Number of the MONICA Population Survey
1 = baseline
2 = middle
3 = final 		|__| 14

If three surveys are carried out in the MONICA Reporting Unit enter 1 for the first, 2 for the middle and 3 for the third survey. If only two surveys (i.e. the first and the final) are carried out, code 1 for the first and 3 for the second.

Item 7

7 SAMUNIT Sampling stratum or primary unit
888 = the person was the primary unit of sampling and no stratification except possibly by age and sex was used
999 = insufficient data 		|__|__|__| 15 to 17

If the sample had stratification other than by age and sex, or if multi-stage sampling was used, please give here the code of the stratum and/or the primary sampling unit from which the person was selected. The code numbers should be issued by the MCC in such a way that they uniquely define the strata and the sampling units. The relation between the codes used and the sampling scheme should be described in a letter which should follow the data transfer.

If you have any uncertainty concerning the coding of this item, please contact the MONICA Data Centre for instructions.

Item 8

8 DEXAM Date of examination (day, month, year) |__|__||__|__||__|__| 18 to 23

If the person attended the survey examination, enter here the exact date when the physical/clinical examination of the person was carried out. If the person comes to the clinic more than once enter here the date which best identifies the day of the risk factor assessments (smoking, blood pressure, venous blood specimen taken for cholesterol).

The first two columns are reserved for the day of the examination; code 01 - 31 for specific dates. The third and fourth columns are reserved for the month of the examination; code 01 - 12. The last two columns are for the year, but only the last two digits are entered and the first two digits (19) are not entered.

If the person returns the completed questionnaire by mail but does not come to the clinic and has left this item blank, enter here the date of return of the mailed questionnaire.

Please make sure that all dates correspond with the study period in your centre.

The last two columns are for the year, but only the last two digits are entered; do not code the first two digits (19). If the year of birth is not known, code a year of birth derived from an estimate of the age. Records with the year of birth entered as 99 (not known) are not acceptable because they cannot be allocated to an age group.

Record the average number of cigarettes smoked daily. Include subjects who smoke hand-rolled cigarettes regularly. If CIGS = 1 this item corresponds to Question 2 of the Smoking Questionnaire.If CIGS = 3 this item corresponds to Question 4 of the Smoking Questionnaire. Please make sure that the data for this item are extracted from the relevant question of the Smoking Questionnaire for each subject.

For the amounts 1 - 9, code 001 - 009 and for amounts 10 - 99, code 010 - 099.
Code 888 if CIGS = 2.

This question has been added to clarify the pattern of smoking. An ambiguity existed in the old questionnaire whereby a person who smoked a lot on one day could not be differentiated from someone who smoked a little every day.

In an earlier version of the Smoking Questionnaire this question had also the option of "every day", which applied to regular smokers only. If such a Smoking Questionnaire was used, code 8 for the "every day" answers.

Item 18

Code 2 if the answer is "No"
Code 8 if CIGS = 1
Code 9 if Insufficient Data.

The earlier Smoking Questionnaires had an option for "Occasional past smoking" and this item was not to be asked of "Current occasional smokers". If such a Smoking Questionnaire was used (which was the case in most MCCs for the Second Survey) code 2 for "Occasional past cigarette smokers", and code 9 for "Current occasional smokers".

Item 19

Code 8888 if "Smoking regularly now" or "Never smoked regularly" (i.e. CIGS = 1 or EVERCIG = 2).

In the earlier Smoking Questionnaires this item was not to be asked of "Current occasional smokers". If such a Smoking Questionnaire was used (which was the case in most MCCs for the Second Survey, code 9999 for "Current occasional smokers."

Item 20
