| 摘 要： | 目的 探究儿童恒磨牙早萌的流行病学特征及其与体质量指数(BMI)的关联，为促进儿童口腔健康提供参考。 方法 整群选取蚌埠市2所小学861名9~12岁儿童，开展父母问卷采集社会人口统计学信息，检查并记录第二恒磨牙萌出情况。采用多因素Logistic回归模型和边际效应命令分别探讨体重状态及BMI与第二恒磨牙早萌风险的关联。 结果 第二恒磨牙早萌检出率为26.5%(228名)，其中男童检出率为27.5%，女童为24.9%，差异无统计学意义(χ2=0.73，P=0.39)。肥胖组儿童第二恒磨牙早萌检出率(39.0%)高于正常体重组(21.5%)(χ2=21.85，P < 0.01)。肥胖与第二恒磨牙早萌风险呈正相关(OR=3.55，95%CI=2.14~5.87，P < 0.01)；超重与第二恒磨牙早萌风险的关联无统计学意义(OR=1.64，95%CI=0.95~2.81，P=0.07)。女童较同年龄男童第二恒磨牙早萌发生风险更高(OR=2.19，95%CI=1.42~3.39，P < 0.01)。 结论 肥胖儿童恒磨牙早萌发生风险显著增加，同年龄女童第二恒磨牙早萌较男童常见。

| Abstract: | Objective To investigate the epidemiological characteristics of premature eruption of permanent molars and its aasociation with body mass index (BMI), to provide a reference for childhood oral health promotion. Methods A total of 861 children aged 9 to 12 years from two primary schools in Bengbu City were selected by cluster sampling method. Parental questionnaire was administered to collect socio-demographic information. The eruption of second permanent molars were examined. Data was analyzed by multivariate Logistic regression model and margins command. Results The detection rate of premature eruption of second permanent molars was 26.5%(228), 27.5% in boys and 24.9% in girls(χ2=0.73, P=0.39). Early detection rate of second permanent molars (39.0%) was significantly higher in obese group than normal weight group (21.5%)(χ2=21.85, P < 0.01). Logistic regression analysis showed that obesity was positively correlated with the risk of premature eruption of second permanent molars(OR=3.55, 95%CI=2.14-5.87, P < 0.01). Overweight was not associated with higher risk of premature eruption of second permanent molars(OR=1.64, 95%CI=0.95-2.81, P=0.07). Being female was associated with higher risk of premature eruption of second permanent molars compared to age-matched peers(OR=2.19, 95%CI=1.42-3.39, P < 0.01). Conclusion Childhood obesity is associated with higher risk for premature eruption of second permanent molars. Girls are more likely to have second permanent molar erupted in advance compared to age-matched boys. |
