Beverage Intake Assessment Questionnaire: Relative Validity and Repeatability in a Spanish Population with Metabolic Syndrome from the PREDIMED-PLUS Study

Abstract

We assess the repeatability and relative validity of a Spanish beverage intake questionnaire for assessing water intake from beverages. The present analysis was performed within the framework of the PREDIMED-PLUS trial. The study participants were adults (aged 55–75) with a BMI ≥27 and <40 kg/m2, and at least three components of Metabolic Syndrome (MetS). A trained dietitian completed the questionnaire. Participants provided 24-h urine samples, and the volume and urine osmolality were recorded. The repeatability of the baseline measurement at 6 and 1 year was examined by paired Student’s t-test comparisons. A total of 160 participants were included in the analysis. The Bland–Altman analysis showed relatively good agreement between total daily fluid intake assessed using the fluid-specific questionnaire, and urine osmolality and 24-h volume with parameter estimates of −0.65 and 0.22, respectively (R2 = 0.20; p < 0.001). In the repeatability test, no significant differences were found between neither type of beverage nor total daily fluid intake at 6 months and 1-year assessment, compared to baseline. The proposed fluid-specific assessment questionnaire designed to assess the consumption of water and other beverages in Spanish adult individuals was found to be relatively valid with good repeatability.

Development and relative validity of a self‐administered semi‐quantitative drinks frequency questionnaire, validated in a population of university students

“…16,22,40,41 Because of the importance of accurately recording drinks consumption, several fluid-specific questionnaires have been validated in other languages. 13,42 In Greece, a similar tool was developed some years ago, 43 evaluating water intake from liquid, solid foods and water, as well as urine, faeces and sweat water loss. However, because of its different aim, it is not a quick assessment tool, as the DFQ.…”

Challenges in the assessment of total fluid intake in children and adolescents: a discussion paper

“…Studies to date have indicated that 24-h recalls significantly underestimate intake when compared to a 7-day diary [37]. A few beverage-specific questionnaires have been developed with promising early results [32, 33], and a recent study in adults has demonstrated the validity and reliability of a 7-day fluid record using total body water turnover [34]. …”

“…Using both the urine osmolality and the 24-h urine volume analysis, 66% of individuals were categorised in the same or adjacent quintile, demonstrating a reasonably good level of questionnaire validity. The questionnaire also demonstrated good repeatability; the difference between baseline measurement of total fluid intake and the measurement after 6 months and 1 year were not significant [ 32 ]. The Water Balance Questionnaire was adapted for use with Greek pregnant women and when compared to urine hydration indices, it was considered to be valid [ 33 ].…”

Relative Validity of a Beverage Frequency Questionnaire Used to Assess Fluid Intake in the Autosomal Dominant Polycystic Kidney Disease Population

“…To our knowledge, no previous studies have validated a beverage intake questionnaire in a chronic kidney disease population. In fact, to date, we identified only three beverage questionnaire validation studies, and these were evaluated in a general healthy population [ 6 , 17 , 18 ]. Hedrick et al [ 6 ] validated a questionnaire against food records ( r = 0.456, p < 0.001); whereas, questionnaires by Ferreira-Pago et al [ 17 ] and Malisova et al [ 18 ] were validated against 24-h urine volume ( r = 0.447, p = 0.0003; r = 0.29, p = 0.015, respectively) and osmolality ( r = −0.447, p = 0.0005; r = −0.30, p = 0.010, respectively).…”
