目的估计母亲的教育对土著澳大利亚儿童的龋齿经验的影响，同时控制儿童的甜食intake.MethodsThe土著儿童的纵向研究是一项研究的土著澳大利亚儿童，年龄从6个月至2年（婴儿队列）和3.5至5年（儿童队列）在基线的两个代表性的队列。2008年，对儿童的主要照料者进行了一次面对面的访谈，并在随后的4年中每年重复一次。数据包括家庭人口统计、儿童健康（营养信息和牙齿健康）、产妇状况和最高资格水平。母亲受教育程度分为4类：0-9岁、10岁、11-12岁和>12岁。儿童的平均甜食摄入量为30%。缺失值的多重插补后，稳定的逆概率权重的边际结构模型被用来估计母亲的教育水平对儿童的蛀牙experience.ResultsFrom 2008年至2012年，完整的数据1720母子二人组。5年期间，儿童患龋率为42.3%。母亲文化程度对儿童龋病的控制直接效应估计值为1.21（95% CI：1.01-1.45），1.03（95% CI：0.91-1.18）和1.07（95% CI：0.93-1.22）;缺失值多重插补后，效应为1.21（95% CI：1.05-1.39），1.06（95% CI：0.94-1.19）和1.06（95%置信区间：0.95-1.19），比较0- 9 '，10'和11-12'年到>结论母亲的教育水平对儿童的龋齿经历有直接的影响，而不是通过甜食的摄入来介导的以及使用边际结构模型估计时的其他风险因素。
ObjectiveTo estimate the effect of mothers' education on Indigenous Australian children's dental caries experience while controlling for the mediating effect of children's sweet food intake.MethodsThe Longitudinal Study of Indigenous Children is a study of two representative cohorts of Indigenous Australian children, aged from 6 months to 2 years (baby cohort) and from 3.5 to 5 years (child cohort) at baseline. The children's primary caregiver undertook a face-to-face interview in 2008 and repeated annually for the next 4 years. Data included household demographics, child health (nutrition information and dental health), maternal conditions and highest qualification levels. Mother's educational level was classified into four categories: 0-9 years, 10 years, 11-12 years and >12 years. Children's mean sweet food intake was categorized as 30%. After multiple imputation of missing values, a marginal structural model with stabilized inverse probability weights was used to estimate the direct effect of mothers' education level on children's dental decay experience.ResultsFrom 2008 to 2012, complete data on 1720 mother-child dyads were available. Dental caries experience for children was 42.3% over the 5-year period. The controlled direct effect estimates of mother's education on child dental caries were 1.21 (95% CI: 1.01-1.45), 1.03 (95% CI: 0.91-1.18) and 1.07 (95% CI: 0.93-1.22); after multiple imputation of missing values, the effects were 1.21 (95% CI: 1.05-1.39), 1.06 (95% CI: 0.94-1.19) and 1.06 (95% CI: 0.95-1.19), comparing 0-9', 10' and 11-12' years to > 12 years of education.ConclusionMothers' education level had a direct effect on children's dental decay experience that was not mediated by sweet food intake and other risk factors when estimated using a marginal structural model.
