Here is the study that looked at beverage consumption, using sample sizes which are relatively smaller. One part of this study compared 20 children who were 7 to 10 years old with the 5 who were 11 to 13. The younger children consumed average of 8.2 oz of sweetened drinks for each day while the older ones averaged 14.5 oz. The standard deviations were 10.7 oz as well as 8.2 oz respectively.
