摘要:
目的 了解广州市5岁儿童重度龋病发生的影响因素，为制订科学、有效的防控措施提供理论依据。方法 在人群调查的基础上，按照1：1配对原则筛选出244对重度龋和无龋儿童组成病例组和对照组，采用单因素和多因素条件Logistic回归方法分析儿童重度龋病的影响因素。结果 多因素条件Logistic回归分析结果显示低出生体重（OR=3.08，95%CI：1.00~9.43，P=0.049），高出生体重（OR=2.30，95%CI：1.06~4.97，P=0.035），经常进食甜食（OR=2.17，95%CI：1.07~4.44，P=0.033），睡前有进食甜食习惯（OR=1.80，95%CI：1.08~12.98，P=0.023）以及父母年龄（OR=0.50，95%CI：0.28~0.87，P=0.015）是广州市5岁儿童重度龋病发生的影响因素。结论 父母应重视儿童乳牙龋的发生，从小培养儿童形成良好的饮食行为习惯，降低重度婴幼儿龋病的发生率。

Abstract:
Objective To study the risk factors of severe early childhood caries (SECC) among 5 years old children in Guangzhou, and to provide theoretical evidence for developing scientific and effective interventions. Methods 1:1 matched case-control study was conducted in 244 cases with SECC and 244 controls with no caries based on population survey. Univariate and multivariate conditional Logistic regressions were used to analyze the factors influencing SECC. Results Multivariate conditional Logistic regression showed that low birth weight (OR=3.08, 95% CI:1.00-9.43, P=0.049), high birth weight (OR=2.30,95%CI:1.06-4.97,P=0.035) regular eating sweets (OR=2.17, 95% CI:1.07-4.44, P=0.033), habit of eating sweets before bedtime (OR=1.80, 95% CI:1.08-2.98, P=0.023), parent age (OR=0.05, 95% CI:0.28-0.87, P=0.015) were risk factors for the occurrence of SECC among 5 years old children in Guangzhou. Conclusions Parents should pay more attention to children's deciduous caries, and good eating habits should be developed from younger age for reducing SECC occurrence.
