目的对比重症龋和无龋学龄前儿童的血红蛋白和维生素D水平。方法 2012~2013年从儿保门诊中选取206名儿童;其中111名患重症龋,95名无龋齿。由父母或监护人完成一份问卷调查,同时儿童进行口腔检查和实验室检测。统计方法包括描述性统计、t检验、卡方检验、Fisher精确检验。结果所有儿童的平均血红蛋白水平为(114.49±10.52)g/L,平均1,25(OH)2D3水平为(75.56±30.47)nmol/L。重症龋儿童平均血红蛋白水平〔(111.37±8.71)g/L〕显著低于无龋齿儿童〔(118.55±7.87)g/L〕(P<0.001)。重症龋儿童平均1,25(OH)2D3水平〔(69.38±25.03)nmol/L〕显著低于无龋齿儿童〔(82.76±33.06)nmol/L〕(P<0.001)。结论重症龋儿童与无龋齿儿童相比,血红蛋白及维生素D水平低,差异显著。
Objective To compare hemoglobin and vitamin D levels in preschool children with severe and caries-free caries. Methods From 2012 to 2013, 206 children were selected from child-care clinics; 111 of them suffered from severe caries and 95 had no caries. A questionnaire survey was completed by parents or guardians, while children had oral and laboratory tests. Statistical methods include descriptive statistics, t-test, chi-square test, Fisher’s exact test. Results All children had a mean hemoglobin level of (114.49 ± 10.52) g / L and an average of 1,25 (OH) 2D3 level of (75.56 ± 30.47) nmol / L. The average hemoglobin level in children with severe caries [(111.37 ± 8.71) g / L] was significantly lower than that in caries-free children (118.55 ± 7.87 g / L〕 (P <0.001). The average 1,25 (OH) 2D3 level in children with severe caries [(69.38 ± 25.03) nmol / L) was significantly lower than that in children without caries (82.76 ± 33.06 nmol / L) (P <0.001). Conclusion Compared with children without caries, children with severe caries have lower levels of hemoglobin and vitamin D, the difference is significant.
