Note for the HTML-version: These instructions were extracted word to word from Version 6 of Form 04, which was part of the November 1990 revision of the MONICA Manual. Therefore, references to other sections of the Manual also refer the November 1990 revision, which has not been converted to HTML.

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.

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 subsections 4.9 and 4.10.

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:

Item 1

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

Item 2

2 VERSN Form version |_6| 3

Enter the version number printed on the form. If the number is not 6 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 Code |__|__| 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.

The circumference should be measured on subjects without heavy outer garments in standing position. The contents of all pockets must be removed. All tight clohting, including the belt, must be losened before the measurement is taken. A plastic metric tape should be used. The participant should stand with the feet fairly close together (about 12-15 cm) with weight equally distributed on each leg. Participants should be asked to breath normally, and at the time of the reading of the measurement be asked to breath out gently. This will prevent subjects from contracting their muscles or from holding their breath. The tape should be held firmly and its horizontal position should be ensured. It is recommended that the observer is sitting by the participant while taking the measurements.

This item is optional and was not inclued in the questionnaire until 1988. However, MCCs which have collected these data, or are planning their next survey are strongly encouraged to record this item.
