Abstract

Interrupted time series analysis. An interrupted time series (ITS) analysis was conducted to determine if there was an association between the announcement and implementation of the soft drinks industry levy (SDIL) and rates of hospital admission for tooth extractions due to dental caries in children. Hospital Episode Statistics (HES) were used on hospital admissions for tooth extraction of one or more primary or permanent tooth due to a primary diagnosis of dental caries in children aged 0–18 years attending a National Health Service (NHS) hospital in England from January 2012 (pre-SDIL) to February 2020 (post-SDIL implementation). HES data were grouped and summarised by Index of Multiple Deprivation (IMD) and age group. There was an absolute reduction of 3.7% (95% CI 5.3% to 2.2%) per 100,000 population/month and a relative reduction of 12.1% (95% CI 17.0% to 7.2%) in hospital admissions for carious tooth extractions in all children (0–18 years) compared if there had been no announcement of the SDIL (counterfactual scenario). Reductions were observed in children living in most areas regardless of the level of deprivation and most notably in the youngest children (<10 years). An ITS analysis of administrative data on hospital admissions found the announcement of the UK SDIL was associated with improvements (reduction) in the incidence of hospital admissions for tooth extractions due to dental caries. This study provides evidence of benefits of the UK SDIL to children’s oral health.

英国软饮料行业征税对儿童蛀牙有何影响？

设计数据分析：通过间断时间序列（ITS）分析，确定软饮料行业征税（SDIL）的宣布和实施与儿童因龋齿而入院拔牙的比率之间是否存在关联。研究使用了医院病例统计（Hospital Episode Statistics，HES）数据，统计的是 2012 年 1 月（软饮料行业税征收前）至 2020 年 2 月（软饮料行业税征收实施后）期间，在英格兰国民健康服务（NHS）医院就诊的 0-18 岁儿童中，因主要诊断为龋齿而拔除一颗或多颗乳牙或恒牙的入院率。HES数据按多重贫困指数（IMD）和年龄组进行了分组和汇总：结果：与未公布《特殊和差别化法律》的情况（反事实情况）相比，所有儿童（0-18 岁）因龋齿而入院拔牙的绝对人数减少了 3.7%（95% CI 5.3% 至 2.2%）/100,000 人/月，相对人数减少了 12.1%（95% CI 17.0% 至 7.2%）。无论贫困程度如何，大多数地区的儿童住院率都有所下降，最年幼的儿童住院率下降最为明显（结论：儿童龋齿拔除住院率下降的原因是他们的生活水平较低：对入院管理数据的 ITS 分析发现，英国 SDIL 的公布与因龋齿而入院拔牙的发生率的改善（减少）有关。这项研究提供了英国 SDIL 对儿童口腔健康有益的证据。
