Abstract

Introduction Tooth extraction due to dental caries is associated with socioeconomic deprivation and is a major reason for elective childhood hospital admissions in England. Consumption of sugar-sweetened beverages is a risk factor for dental caries. We examined whether the soft drinks industry levy (SDIL), announced in March 2016 and implemented in April 2018, was associated with changes in incidence rates of hospital admissions for carious tooth extraction in children, 22 months post-SDIL implementation. Methods Changes in incidence rates of monthly National Health Service hospital admissions for extraction of teeth due to a primary diagnosis of dental caries (International Classification of Diseases; ICD-10 code: K02) in England, between January 2012 and February 2020, were estimated using interrupted time series and compared with a counterfactual scenario where SDIL was not announced or implemented. Periodical changes in admissions, autocorrelation and population structure were accounted for. Estimates were calculated overall, by Index of Multiple Deprivation (IMD) fifths and by age group (0–4 years, 5–9 years, 10–14 years, 15–18 years). Results Compared with the counterfactual scenario, there was 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). Children aged 0–4 years and 5–9 years had relative reductions of 28.6% (95% CI 35.6% to 21.5%) and 5.5% (95% CI 10.5% to 0.5%), respectively; no change was observed for older children. Reductions were observed in children living in most IMD areas regardless of deprivation. Conclusion The UK SDIL was associated with reductions in incidence rates of childhood hospital admissions for carious tooth extractions, across most areas regardless of deprivation status and especially in younger children.

英国软饮料行业征税对儿童龋齿拔牙住院的估计影响:中断时间序列分析
由于龋齿而拔牙与社会经济贫困有关,是英国儿童选择性住院的主要原因。饮用含糖饮料是患龋齿的一个危险因素。我们研究了2016年3月宣布并于2018年4月实施的软饮料行业税(SDIL)是否与实施后22个月儿童龋齿住院率的变化有关。方法初步诊断为龋齿的每月国民保健院拔牙住院率的变化(国际疾病分类;使用中断时间序列对2012年1月至2020年2月期间英国的ICD-10代码:K02进行了估计,并与未宣布或实施SDIL的反事实情景进行了比较。考虑了招生、自相关和人口结构的周期性变化。根据多重剥夺指数(IMD)五分之一和年龄组(0-4岁、5-9岁、10-14岁、15-18岁)计算总体估计值。结果与反事实情景相比,所有儿童(0-18岁)因龋齿拔牙入院的相对减少了12.1% (95% CI 17.0%至7.2%)。0-4岁和5-9岁儿童的相对下降分别为28.6% (95% CI 35.6%至21.5%)和5.5% (95% CI 10.5%至0.5%);在年龄较大的儿童中没有观察到变化。生活在大多数贫困地区的儿童,不论是否贫困,都出现了减少。结论:英国SDIL与儿童龋齿住院率的降低有关,在大多数地区,无论贫困状况如何,尤其是在年幼的儿童中。试验注册号ISRCTN18042742。
