To investigate risk indicators for untreated dental decay among Indigenous Australian children using a national representative sample.
Data were from the National Child Oral Health Study 2012-2014, which included a nationally representative sample of Indigenous Australian children aged 5-14 years. Outcomes were the prevalence (% ds/DS >0) and severity (mean ds/DS) of untreated dental decay at the tooth surface level. Caries of the primary dentition was estimated among 5- to 10-year-olds, while that of the permanent dentition was among 8- to 14-year-olds. Independent variables included residential location, household income, frequency and age commencement of toothbrushing, sugar-sweetened beverages (SSB) consumption, dental visiting and residential fluoridation status. Multivariable log-Poisson regression models with robust standard error estimation were used to identify risk indicators for untreated decay. The complex sampling design was taken into account in all analyses.
There were 720 5- to 10-year-old and 736 8- to 14-year-old Indigenous children. Indigenous children experienced significant amount of untreated dental caries. Among 5- to 10-year-olds, % ds >0 was 43.1 (95% CI: 36.8-49.6) and mean ds was 3.4 (95% CI: 2.4-4.4). Among 8- to 14-year-olds, % DS >0 was 27.3 (22.3-32.9), while mean DS was 0.8 (0.6-1.0). In multivariable modelling, risk indicators for % ds >0 among 5- to 10-year-olds were low household income, commencing toothbrushing after 30 months of age, consuming 2+ cups of SSB per day and not residing in fluoridated areas. Risk indicators for mean ds among 5- to 10-year-olds included infrequent toothbrushing and consuming 2+ cups of SSB per day. Risk indicators for % DS >0 among 8- to 14-year-olds were low household income, while risk indicators for mean DS among 8- to 14-year-olds were residing in non-capital city, low household income, consuming 2+ cups of SSB per day and not residing in fluoridated areas.
Indigenous Australian children experienced significant amount of untreated dental caries. Risk indicators for untreated decay included demographic factors, socioeconomic factors, oral hygiene behaviours, dietary behaviours and environmental factors.
利用全国代表性样本调查澳大利亚原住民儿童未治疗龋齿的风险指标。
数据来自于 2012-2014 年全国儿童口腔健康研究，该研究包括了年龄在 5-14 岁的具有全国代表性的澳大利亚原住民儿童。结果是根据牙齿表面计算的未治疗龋齿的流行率（% ds/DS>0）和严重程度（平均 ds/DS）。5-10 岁儿童估计有原发性龋齿，8-14 岁儿童估计有永久性龋齿。自变量包括居住地点、家庭收入、刷牙频率和起始年龄、糖饮料（SSB）的消费、看牙医和居住地区的氟化物状况。采用稳健标准误差估计的多变量对数泊松回归模型来确定未治疗龋齿的风险指标。在所有分析中都考虑了复杂的抽样设计。
有 720 名 5-10 岁儿童和 736 名 8-14 岁儿童。澳大利亚原住民儿童患有严重的未治疗龋齿。在 5-10 岁儿童中，% ds>0 为 43.1（95%CI：36.8-49.6），平均 ds 为 3.4（95%CI：2.4-4.4）。在 8-14 岁儿童中，% DS>0 为 27.3（22.3-32.9），平均 DS 为 0.8（0.6-1.0）。在多变量建模中，5-10 岁儿童% ds>0 的风险指标是家庭收入低、30 个月后开始刷牙、每天饮用 2 杯以上 SSB 和未居住在氟化物地区。5-10 岁儿童平均 ds 的风险指标包括刷牙不频繁和每天饮用 2 杯以上 SSB。8-14 岁儿童% DS>0 的风险指标是家庭收入低，而 8-14 岁儿童平均 DS 的风险指标是居住在非首府城市、家庭收入低、每天饮用 2 杯以上 SSB 和未居住在氟化物地区。
澳大利亚原住民儿童患有严重的未治疗龋齿。未治疗龋齿的风险指标包括人口统计学因素、社会经济因素、口腔卫生行为、饮食行为和环境因素。
