OBJECTIVES
To explore the association between oral hygiene status and obesity among preschool children in Hong Kong.
METHODS
Three hundred and twenty-four 5-year-old children in Hong Kong were recruited. Their oral hygiene status was recorded using visible plaque index (VPI). Body height, body weight, waist circumference (WC), hip circumference and triceps skinfold thickness (TRSKF) were measured to assess general adiposity (weight/height ratio, W/H; body mass index, BMI), central adiposity (WC; waist/hip ratio, WHR) and peripheral adiposity (TRSKF). The relationships between VPI and W/H, BMI, WC, WHR and TRSKF were examined in bivariate and regression analyses.
RESULTS
Fifty-six per cent of the children were considered to have high VPI (VPI ≥ 65.0%). Logistic regression analyses identified that W/H z-score (OR = 1.28, 95% CI = 1.01-1.61) and WC z-score (OR = 1.25, 95% CI = 1.00-1.58) were associated with high VPI. No association was found after adjusted for socio-demographic status (P > 0.05).
CONCLUSION
Oral hygiene status was not associated with obesity among 5-year-old children in Hong Kong after controlling for socio-demographic factors.
目的
探讨香港学龄前儿童口腔卫生状况与肥胖之间的关系。
方法
在香港招募了 324 名 5 岁儿童。使用可见菌斑指数（VPI）记录他们的口腔卫生状况。测量身高、体重、腰围（WC）、臀围和三头肌皮褶厚度（TRSKF），以评估全身肥胖（体重/身高比，W/H；体重指数，BMI）、中心性肥胖（WC；腰臀比，WHR）和外周性肥胖（TRSKF）。在双变量和回归分析中检查 VPI 与 W/H、BMI、WC、WHR 和 TRSKF 之间的关系。
结果
56%的儿童被认为具有高 VPI（VPI≥65.0%）。逻辑回归分析表明，W/H 得分（OR=1.28，95%CI=1.01-1.61）和 WC 得分（OR=1.25，95%CI=1.00-1.58）与高 VPI 相关。在调整了社会人口统计学因素后，没有发现相关性（P>0.05）。
结论
在控制了社会人口统计学因素后，香港 5 岁儿童的口腔卫生状况与肥胖之间没有关联。
