简要总结
The goal of this cluster randomized controlled trial was to compare the effects of two single-session interventions (sugar-intensive vs. general health control) on added sugar intake, motivation to reduce sugar consumption, and factual knowledge about added sugar 6 weeks later, in a sample of first-semester undergraduates.
详细描述
Excessive sugar consumption is recognized as a critical public health concern. For many young adults, the transition to college presents both risk and a promising opportunity to encourage formation of healthy dietary habits. Capitalizing on this window of opportunity, we conducted a cluster-randomized controlled trial to compare the effects of two single-session interventions on added sugar intake in a sample of first-semester undergraduates. Participants received either an intervention primarily focused on reducing added sugar consumption or a general health behavior intervention with units on physical activity, sleep, and healthy diet. Participants' added sugar intake, motivation to reduce sugar consumption, and factual knowledge about added sugar intake were compared at follow-up.

结局指标
主要结局
Change from Baseline Added-Sugar Consumption at 6 Weeks
时间窗: 6 weeks post-intervention
Change from baseline in consumption of specific high-sugar foods and beverages each day during the week preceding assessment. Using a matrix with days as columns and food/beverage items as rows, participants reported number of servings consumed of each food per day of that week: regular soda/pop/sweet iced tea (12oz), energy drinks (1 can), fully sweetened sports drinks (12oz), sugar-syrup coffee drinks (small = 8-12 oz = 1 serving; med = 1.5 servings; large = 2 servings), mixed drinks/cocktails (1 drink), donut/sweet pastry/danish (1 whole), muffin/cake-type bread slice (1 whole), fresh flavored yogurt (½ cup), cookie/brownie (3 oz), cupcake/slice of cake (1 whole), slice of pie (1 whole), ice cream/frozen yogurt (½ cup), and candy (¼ cup). Servings were multiplied by grams added sugar/serving for each item based on the National Cancer Institute Dietary Health Questionnaire-III, and summed across items to obtain total weekly added sugar.
