儿童超重及肥胖与牙周健康状况的相关性调查

Study on the association between overweight-obesity and periodontal status in children

目的探究10～11岁儿童超重及肥胖与牙周状况之间的关系。方法纳入成都市198名10～11岁儿童,其中男106名,女92名。检查受试者身高、体重、腰围,计算体质指数(BMI)、记录刷牙习惯和牙周状况。以BMI作为标准纳入超重肥胖组(实验组) 98人、正常组(对照组) 100人,以腰围为标准纳入超重肥胖组(实验组) 94人、正常组(对照组) 104人。牙周检查内容包括探诊出血指数(BOP)、可见菌斑指数(VPI)、牙石指数(CI)和探诊深度(PD)。采用χ2检验、t检验、单因素及多因素Logistic回归模型进行分析。结果 BMI和腰围标准分组下,实验组的口腔卫生习惯均差于对照组(P<0.01),BOP、VPI>0.25人数、CI高于对照组(P<0.01),出现PD>3 mm的人数无统计学差异。控制VPI>0.25、口腔卫生习惯不良作为混杂因素,BMI标准的超重/肥胖是BOP>0.25的危险因素(OR=1.911,95%CI 1.02～3.58),腰围标准的超重/肥胖是BOP> 0.25(OR=1.78,95%CI 1.28～3.39)和出现牙石(OR=1.88,95%CI 1.03～3.58)的危险因素。结论 10～11岁儿童中全身性肥胖与BOP相关,腹型肥胖与BOP和出现牙石均存在关联。

Objective To analyze the association between periodontal status and overweight-obesity in children aged 10 to 11. Methods 198 children aged 10 to 11 of both gender （ 106 males and 92 females） in Chengdu were included in this case-control study. Subjects answered questionnaires about their habits of brushing teeth. Anthropometrie examinations of height, weight, waist circumference and clinical examination of bleeding on probing （BOP）, visible plaque index （VPI）, calculus index （CI） and probing depth （PD） were carried out. Body mass index （BMI） was further calculated. Under the BMI standard, 98 and 100 were respectively included in the overweight and obesity group （test group） and normal group （control group） , while under the waist circumference standard , 94 and 104 were included in the test group and control group. χ^2 test, t test, bivariate and muhivariate Logistic regression model were used to analyze data. Results Under both standards, the test group showed worse oral hygiene status （ P〈0.01 ） , higher BOP, larger population of VPI〉0.25 and CI （P〈0.01） than the control group. No statistically significant difference was found between groups regarding PD〉3mm. In multivariate Logistic regression analysis, keeping VPI〉0.25 and poor oral hygiene as confounding factors, overweight-obesity under the BMI standard was a risk factor of BOP 〉0.25 （OR = 1.911,95% CI 1.02-3.58 ） , while overweight-obesity under the waist circumference standard was a risk factor of both BOP〉0.25 （OR-= 1.78,95% CI 1.28-3.39） and occurrence of calculus （OR= 1.88, 95% CI 1.03-3.58）. Conclusion In children aged 10 to 11, systemic obesity is associated with BOP and abdominal obesity is associated with both BOP and occurrence of calculus.
