Description:Purpose:
To compare the performance of one survey screener question measuring total sugar-sweetened beverage (SSB) intake to a screener measuring SSB types separately using four questions.
Design:
Cross-sectional.
Setting:
Web-based 2014 SummerStyles survey.
Subjects:
4,167 U.S. adults (≥18 years).
Measures:
Frequency of SSB intake measured using one screener question was compared to frequency using a four-question screener (regular soda, fruit drinks, sports/energy drinks, sweetened coffee/tea). SSB intake (number of times/day) was categorized as 0, >0 to <1, and ≥1 time/day; difference in mean intake was calculated between four questions versus one.
Analysis:
Paired t-tests were used, and agreement was evaluated using weighted kappa and Lin’s Concordance Correlation Coefficient (CCC).
Results:
Mean SSB intake was 1.7 (95% CI: 1.65–1.79) times/day using four questions and 0.6 (95% CI: 0.56–0.62) times/day using one question (p<0.001). Intake frequency based on four questions vs. one, respectively, was 16.0% vs. 38.5% for 0 times/day, 15.6% vs. 42.5% for >0 to <1 time/day, and 68.4% vs. 18.9% for ≥1 time/day. There was fair agreement for the three SSB intake categories (kappa: 0.27), and poor absolute agreement between the two continuous measures (Lin’s CCC: 0.31).
Conclusion:
Daily SSB intake was significantly lower using one screener question versus a four-question screener. Researchers should assess SSB types separately or consider that daily SSB intake is likely underestimated with one question.
