This cross-sectional study developed and evaluated an online Arabic Beverage Frequency Questionnaire (ABFQ) for assessing beverage intake. The ABFQ showed good reliability but could not be validated using 24-hour urine osmolality alone.
Participants completed the ABFQ twice (7-20 days apart) and provided one 24-hour urine sample. For validity, average daily beverage consumption from the first questionnaire was compared to urine osmolality, showing a weak, non-significant negative correlation (r_s = -0.2, p = 0.12).
