Summary
The Beverage Intake Questionnaire (BEVQ-15) was adapted for Turkish adults, resulting in the BEVQ-21. This revised questionnaire shows good validity and reproducibility for assessing beverage consumption in Turkey.
Area of Science:
- Nutrition Science
- Dietary Assessment Tools
- Public Health
Background:
- Accurate assessment of beverage intake is crucial for understanding dietary patterns and health outcomes.
- Existing questionnaires may not adequately capture the beverage consumption habits of specific populations.
- Cultural adaptation of dietary assessment tools is essential for their validity and utility.
Purpose of the Study:
- To translate and culturally adapt the Beverage Intake Questionnaire (BEVQ-15) for the Turkish population.
- To evaluate the validity and reproducibility of the adapted questionnaire, named BEVQ-21.
- To ensure the BEVQ-21 accurately reflects Turkish beverage preferences and consumption patterns.
Main Methods:
- The Beverage Intake Questionnaire (BEVQ-15) was translated and culturally adapted for Turkish adults, leading to the BEVQ-21.
- The BEVQ-21 included specific categories for black tea, coffee, herbal tea, mineral water, kefir, and turnip juice.
- Validity and reproducibility were assessed through repeated administrations of the BEVQ-21 and comparison with a three-day dietary record in 51 participants.
Main Results:
- The adapted BEVQ-21 showed minimal yet significant differences compared to dietary records for various beverage categories (mL and kcal).
- Bland-Altman plots indicated consistency in differences for water, milk, soft drinks, black tea, herbal teas, and total beverage intake.
- Reproducibility analysis revealed significant associations for sugary and total beverage consumption between the two BEVQ-21 administrations (r=0.44-0.65).
Conclusions:
- The culturally adapted BEVQ-21 is a valid and reproducible tool for assessing beverage intake in the Turkish adult population.
- The modifications made to the BEVQ-15, such as individualizing tea and water categories, improved its relevance for Turkish dietary habits.
- The BEVQ-21 can be reliably used in research and clinical settings to evaluate beverage consumption patterns in Turkey.

143
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
451
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
