Due to limited information on associations between health‐related knowledge and attitudes and sugars‐sweetened beverage (SSB) intake, our study examined this question using the 2010 HealthStyles Survey data for 3,835 adults (≥18 years). Multivariable logistic regression was used to estimate the adjusted odds ratios (OR) for drinking SSB ≥2 times/day. About 31% of adults consumed SSBs ≥1 time/day, with 20.5% doing so ≥2 times/day. Most adults (84.5%) agreed that drinking SSB can cause weight gain. However, the majority of adults did not know the actual calorie content of 24‐oz fountain soda (19% underestimated, 17% overestimated, and 45% did not know). Only 28.2% of adults agreed that if the price for a 20‐oz regular soda increased by $0.50 but the price of diet soda remained the same, they would switch to the diet soda. After adjusting for sociodemographic factors, the odds for drinking SSBs ≥2 times/day were significantly higher among adults who neither agreed nor disagreed (neutral) that drinking SSB can cause weight gain (OR=1.70 vs. agree), adults who underestimated the calorie content of regular soda (OR=1.52 vs. do not know), and adults who disagreed that if the price for a 20‐oz regular soda increased, they would switch to diet soda (OR =1.48 vs. agree). Our findings suggest a need for health education regarding the caloric content of SSBs and menu labeling can be a form of education information.
