Introduction This manual focuses on the variables and indicators of Food Consumption Database. These variables have been collected by the GloboDiet Tool and self- reported questionnaires (Food Frequency Questionnaires). To the GloboDiet consumption data other data have been added a posteriori: - Food composition table data from the Nubel or Nevo databank (2015) - Some essential background variables/indicators from the General database (like age, gender, etc.) All data are organised at the individual level. A person selected through sampling and having agreed to participate in the survey is considered as a participant. In children (3-9 years) a parent or legal guardian was used as a proxy respondent. Each line represents a food or food supplement consumption, as reported by the participant or his/her proxy. This section aims to list all variables stated in the questionnaires and explain all indicators constructed on their basis. Variables and indicators are presented by topic. The French and Dutch versions of the questionnaires are available on the website of the Food Consumption Survey 2014-2015: Dutch version: https://fcs.wiv-isp.be/nl/SitePages/Vragenlijsten.aspx French version: https://fcs.wiv-isp.be/fr/SitePages/Questionnaires.aspx Before starting any analyses on the consumption data, please read carefully some important remarks mentioned in chapter 3 “Food consumption interview (Epic-Soft)” in order to be able to use this database correctly. 3 2.

A total of 64 groups participated to the survey. A group is largely equivalent to a ‘municipality’. Nevertheless, in the case of large cities, several groups can be allocated to a similar municipality. Fourth digit: trimester of sampling (1,2,3,4) Fifth and sixth digit: The sixth digit refers to the age-gender stratum of participant: 1 = 3-5 years male 2 = 3-5 years female 3 = 6-9 years male 4 = 6-9 years female 5 = 10-17 years male 6 = 10-17 years female 7 = 18-39 years male 8 = 18-39 years female 9 = 40-64 years male 0 = 40-64 years female The fifth digit refers to the number of the selected person in that stratum. (caution: for a participant from the first trimester the fifth and the sixth digit both refer to the age-gender stratum (1-10)) The seventh digit: identification of the cluster (1, 2, 3, 4) A cluster is an ensemble of 4 people who were considered as “equivalent” in the sampling process (same municipality of residence, gender and age). The principle behind the clustering is that one person of each cluster should take part in the survey. The eight digit: identification of the individual in the cluster (1, 2, 3, 4) Denominator All participants 5 Remarks Example: The participant with id “31231711”: Is living in the Walloon region (3) Belongs to group 312 (is living in Liège) Was sampled for the third trimester Refers to a participant of the first age- gender stratum (male between 3-5 years) Refers to the seventh selected person in that stratum Belongs to the first cluster Is the second individual within that cluster Variable FCS2014 INT_DATE Title Date of EPIC interview Type of variable Num Possible value Between 01/02/2014 and 16/04/2015 Value labels DD/MM/YYYY Denominator All participants Remarks / Variable FCS2014 INT_DAY Title Day of EPIC interview Type of variable Num Possible value 1 to 7 Value labels 1=Monday 2=Tuesday 3=Wednesday 4=Thursday 5=Friday 6=Saturday 7=Sunday Denominator All participants Remarks / Variable FCS2014 INT_NUM Title EPIC interview number Type of variable Num Possible value 1 or 2 Value labels 1=first epic interview day 2=second epic interview day Denominator All participants Remarks / Variable FCS2014 Date_rec 6 Title Date of recalled day Type of variable Num Possible value Between 01/31/2014 and 05/29/2015 Value labels MM/DD/YYYY Denominator All participants Remarks / Variable FCS2014 Date_interw Title Date of food frequency questionnaire Type of variable Num Possible value Between 01/04/2014 and 22/04/2015 Value labels DD/MM/YYYY //=missing Denominator All participants Remarks This variable is not cleaned Variable FCS2014 DateFFQ Title Date of supplement frequency questionnaire Type of variable Date Possible value Between 12/06/2014 and 12/05/2015 Value labels DD/MM/YYYY Denominator Subsample – questionnaire was collected from 12/06/2014. Remarks / Indicator FCS2014 WFIN_epic Title Weight of the individual within the sample (food consumption database) Type of variable Num Possible value From 0.041 to 8.245 Value labels / Based on variable(s) Age, prov, season, hc0105, week Construction The weight is the ratio between the population of a stratum (variable "N") and the number of interviews in this stratum (variable "total"), with additionally taking into account the repartition over the “week” & “season” if week = 1 then WFIN_epic = N*25/(total*4*49); else if week = 2 then WFIN_epic = N*4/(total*4*49); else if week = 3 then WFIN_epic = N*20/(total*4*49); The weighting factors are normalized: 7 WFIN_epic = (3146*WFIN_epic)/6858169.9082; Denominator All participants Remarks National statistics from the population by provinces on January 2014 was used to calculate the weighting factor Indicator FCS2014 mark_capi Title Number of available CAPI interviews Type of variable Num Possible value 1 to 2 Value labels 1 = One CAPI interview 2 = Two CAPI interviews Based on variable(s) intervie, intervie2 Construction if intervie=. or intervie2=. then mark_capi=1; else mark_capi=2; Denominator All participants Remarks When the variable ‘intervie’ (date of CAPI interview) is missing no CAPI interview was done.
