News Finding: New U.S. research has compared alcohol brand choices between underage youth (those under 21) &amp; adults:  @username

News Context: New U.S. research has compared alcohol brand choices between underage youth (those under 21) &amp; adults:  @username
Paper Context: There were no substantial differences by region (p=0.11). Therefore, despite our use of analytic weighting, it is possible that our youth brand preference estimates do not fully represent the brand choices of Black and lower income youth, an issue that might further affect the comparability of our youth and adult brand consumption estimates. Finally, it is possible that respondents either exaggerated or underreported their drinking behavior, though it should be pointed out that research long ago established the validity of substance use surveys completed under conditions of anonymity.
