The frequency of consumption of beverages was evaluated by applying the qualitative questionnaire specially designed to measure the habitual intake of beverages in the participants of this study. A retrospective structured interview was asked about the frequency of consumption in the last month. The list used included 39 beverages, grouped into 15 categories following the ANIBES study methodology (18).

For each drink, the participants had to answer for the frequency of intake (daily, weekly or monthly) and the number of times of that frequency selected with options from 1 to 10. Likewise, the participant could declare himself a non-consumer of some drink. Drink in the last month. Because it is a qualitative questionnaire, the portion or quantity consumed was not asked; therefore, the nutritional value of these beverages could not be obtained.

Training of enumerators

The training and standardization of the interviewers were carried out in three stages; in the first one, it was addressed to the interviewers and supervisors who participated in a pilot test in the city of Caracas. Once these results were obtained, the necessary improvements were made. In a second stage, all the interviewers and supervisors who participated in the fieldwork were trained; this training covered the following aspects: the objective of the research, role of the interviewer, approach and selection of the sample subject, description and form of application of the instruments, use of the interviewer’s manuals, use of the help instruments in obtaining data and resolution of doubts. Finally, the third stage was dedicated to standardizing the application of instruments with practical sessions that sought to evaluate the execution, clarify doubts and reinforce the procedures.

Data collection and quality control

The field activity was carried out between May and August 2015. Food intake was evaluated during two visits to the home of the sample subject. Data collection was done so that every day of the week was included and randomly distributed among the study participants. In total, 2264 reminders corresponding to 1132 sample subjects were collected.

To ensure quality control of the data, several strategies were used during the different stages of the study. In the first place, the nutrition team made several visits to each city, and the data collection process was supervised in the field to ensure adequate quality in obtaining them.

After collection, each survey was reviewed by the supervisor in the field in the interviewer’s presence to request clarifications or notice omissions. After this verification, the coordinator sent it to the primary research center, where it was coded and later thoroughly reviewed by the filing team, ensuring that all fields were complete. Finally, the team of nutritionists verified that the record of reminders was adequate.

In any of the cases, when a survey did not meet the quality criteria due to lack of information or clarity, it was returned to the previous step to assess whether the data could be corrected; if this was not possible, the survey was excluded from the final analysis.

Data processing and validation

Transforming the practical measures to the objective amount consumed was carried out by a nutritionist-dietician and corroborated by another colleague. A double-check was also performed for the data transcription process.

After transforming the data into calories and nutrients for each food, the information was added by mealtime and subsequently at the individual level. In addition, the average intake was calculated for the two visits.

The database was also subjected to a quality control process to verify out-of-range values ​​or atypical data. Given the non-normality of the distribution of the consumption data, a logarithmic transformation was carried out using the Multiple Source Method (MSM). The average habitual intake corrected for each of the quantitative data was obtained. This method was developed by the European Prospective Investigation into Cancer and Nutrition (EPIC) and consisted of a mixed method of several steps that requires the application of at least two R24h in a sample to obtain a probabilistic consumption model that is then transformed into a normal distribution with which a better approximation to the usual intake of each person is achieved.
