Introduction:

Dietary exposure is complex to measure and is associated with the development of chronic diseases; therefore, it is necessary to develop and validate simplified instruments for measurement.

Objective:

To establish the classification and validity reproducibility of the 24-hour dietary recall method (24hDR) in food frequency questionnaires (FFQ) developed in Colombia.

Materials and methods:

Diagnostic technology study developed during 2010-2017. Two 24hDR and two FFQs were applied to 523 subjects: 109 in Bogotá D.C., 107 in Medellín, 106 in Cali, 102 in Barranquilla and 99 in Bucaramanga and its metropolitan area. Reproducibility and validity studies were performed using crude Pearson's r coefficients adjusted by residual energy method.

Results:

The reproducibility of 24hDR was poor-moderate (minimum -0.00, maximum 0.72), as was the reproducibility of the questionnaires (minimum -0.01, maximum 0.72). The validity of the questionnaires was poor (minimum -0.01, maximum -0.59).

Conclusion:

FFQs are not useful for epidemiological research, which is explained by the high variability caused by few 24hR recalls in dietary estimation when designing questionnaires, and failures in data collection.
