Results: The proportion of SSBs knowledge score less than 60 points, between 60-79 points and 80-100 points were 5.6%, 41.9% and 52.4%. Multivariate analysis showed that age(4-6 grade, junior middle and high school), gender(female), parents education(high school or vocational schools, colleges and universities as bachelors, masters or doctors), students pay attention to the ingredient list (seldom, none), parental dissuasion or reward behavior (only forced dissuasion, giving no dissuasion, occasional reward, no reward), and the storing beverages at home (seldom, none) were associated with total SSBs knowledge score and milk containing beverage knowledge score ( β =-0.79，-1.19，-1.74，0.58， 1.20 ，1.81，2.98，3.13，2.70，4.85，6.34,6.41，-0.99，-0.78，-1.81，-2.40，5.85，6.26，0.61，1.92， P <0.05).
