Consumption of sugar-sweetened beverages (SSB) is linked to obesity. The authors hypothesized that school-based nutrition education would decrease SSB consumption.
Self-selected interventional cohort with random selection for pre and post measurements.
Arizona Supplemental Nutrition Assistance Program-Education Program-eligible schools.
Randomly selected (9%) fourth- and fifth-grade classroom students.
The University of Arizona Nutrition Network provided general nutrition education training and materials to teachers, to be delivered to their students. The University of Arizona Nutrition Network administered behavioral questionnaires to students in both fall and spring.
MAIN OUTCOME MEASURE(S): Change in SSB consumption.
Descriptive statistics were computed for student demographics and beverage consumption on the day before testing. Paired t tests evaluated change in classroom averages. Linear regression assessed potential correlates of SSB consumption.
Fall mean SSB consumption was 1.1 (± 0.2) times; mean milk and water intake were 1.6 (± 0.2) and 5.2 (± 0.7) times, respectively. Beverage consumption increased (3.2%) in springtime, with increased SSBs (14.4%) accounting for the majority (P = .006). Change in SSB consumption was negatively associated with baseline SSB and water consumption but positively associated with baseline milk fat (P ≤ .05).
The results suggest the need for beverage-specific education to encourage children to consume more healthful beverages in warmer weather.
饮用含糖饮料（SSB）与肥胖有关。作者推测以学校为基础的营养教育会减少SSB的摄入量。
自我选择的干预队列，随机选择进行前后测量。
亚利桑那州符合补充营养援助计划-教育计划的学校。
随机选择（9%）四年级和五年级的班级学生。
亚利桑那大学营养网络向教师提供一般营养教育培训和材料，由教师传授给学生。亚利桑那大学营养网络在秋季和春季对学生进行行为问卷调查。
SSB摄入量的变化。
计算测试前一天学生人口统计学和饮料消费的描述性统计数据。配对t检验评估课堂平均水平的变化。线性回归评估SSB消费的潜在相关因素。
秋季SSB平均摄入量为1.1（±0.2）次；牛奶和水的平均摄入量分别为1.6（±0.2）次和5.2（±0.7）次。春季饮料消费量增加（3.2%），其中SSB增加（14.4%）占大部分（P = 0.006）。SSB消费的变化与基线SSB和水的消费呈负相关，但与基线乳脂呈正相关（P≤0.05）。
结果表明需要针对饮料进行特定教育，以鼓励儿童在天气较暖和时饮用更健康的饮料。
