Purpose: To examine associations of adolescent sugar-sweetened beverage (SSB) intake with parent SSB intake and parent and adolescent knowledge of SSB-related health risks.
Design: Quantitative, cross-sectional.
Setting: 2014 SummerStyles survey.
Subjects: Nine hundred and ninety parent and adolescent (12-17 years) pairs.
Measures: The outcome was self-reported adolescent intake (0, >0 to <1, or ≥1 time/day) of SSBs (soda, fruit drinks, sports/energy drinks, other SSBs). The exposures were self-reported parent SSB intake (0, >0 to <1, ≥1 to <2, or ≥2 times/day) and parent and adolescent knowledge of SSB-related health risks (weight gain, diabetes, and dental caries).
Analysis: Separate multinomial logistic regression models were used to estimate adjusted odds ratios (aORs) for adolescent SSB intake ≥1 time/day (ref: 0 times/day), according to (1) parent SSB intake and (2) parent and (3) adolescent knowledge.
Results: About 31% of adolescents consumed SSBs ≥1 time/day, and 43.2% of parents consumed SSBs ≥2 times/day. Adolescent and parent knowledge that SSB intake is related to health conditions ranged from 60.7% to 80.4%: weight gain (75.0% and 80.4%, respectively), diabetes (60.7% and 71.4%, respectively), and dental caries (77.5% and 72.9%, respectively). In adjusted models, adolescent SSB intake ≥1 time/day was associated with parent intake ≥2 times/day (aOR = 3.30; 95% confidence interval = 1.62-6.74) but not with parent or adolescent knowledge of health risks.
Conclusion: Parental SSB intake may be an important factor in understanding adolescent behavior; knowledge of SSB-related health conditions alone may not influence adolescent SSB behavior.
