Despite widespread recognition among public health experts that childhood sugar-sweetened beverage consumption should be reduced, doing so has proven to be a challenge. An agent-based model of early childhood sugar-sweetened beverage consumption was applied to data from three high-quality, longitudinal cohort studies to gain insight into potentially effective intervention strategies across contexts.
From 2021 to 2023, a single agent-based model design was applied to data sets derived from three separate cohorts of children followed from infancy to childhood, with very different populations and environments (participants recruited in 1999-2002; 2003-2010; and 2009-2014). After assessing its ability to reproduce observed consumption patterns across cohorts, it was used to simulate potential impacts of multiple intervention strategies across contexts.
Interventions reducing home availability of sugar-sweetened beverages consistently had the largest potential effects. Impact differed between cohort settings: a complete decrease in availability resulted in an estimated 87% decrease in overall early childhood consumption for one of the cohorts, compared with 61% and 54% in the others. Reducing availability in center-based child care resulted in substantially greater reduction in one cohort relative to the other two.
There is untapped potential for strategies targeting children's sugar-sweetened beverage consumption in the home, but in some instances, other approaches might also yield meaningful effects. Tailoring approach to setting may be important, and agent-based models can be informative for doing so. This agent-based model has broad generalizability and potential to serve as a tool for designing effective, context-specific strategies to reduce childhood sugar-sweetened beverage consumption.
尽管公共卫生专家普遍认识到应该减少儿童含糖饮料的消费,但事实证明这是一项挑战。本研究应用基于代理的儿童早期含糖饮料消费模型,利用来自三个高质量、纵向队列研究的数据,深入了解跨环境的潜在有效干预策略。
2021 年至 2023 年,应用单一基于代理的模型设计,对三个独立儿童队列的数据进行分析,这些队列的儿童在婴儿期至儿童期被跟踪,具有非常不同的人群和环境(1999-2002 年、2003-2010 年和 2009-2014 年招募参与者)。在评估其在跨队列中再现观察到的消费模式的能力后,它被用于模拟跨环境的多种干预策略的潜在影响。
减少家庭含糖饮料供应的干预措施始终具有最大的潜在影响。干预效果因队列设置而异:在一个队列中,完全减少供应可使整个儿童早期的消费估计减少 87%,而在其他两个队列中则减少 61%和 54%。在日托中心减少供应可使一个队列的含糖饮料消费显著减少。
针对家庭中儿童含糖饮料消费的策略具有尚未开发的潜力,但在某些情况下,其他方法也可能产生有意义的效果。针对特定环境制定方法可能很重要,而基于代理的模型可以为其提供信息。该基于代理的模型具有广泛的通用性和潜力,可以作为设计有效、特定于环境的策略的工具,以减少儿童含糖饮料的消费。
