Objectives
The aims of the study were (1) to assess in 6- to 7-year-old Filipino children caries prevalence and experience and the weight status and (2) to investigate the association between dental caries and weight status.
Materials and methods
Dental and anthropometric examinations were conducted on 1,962 6- to 7-year-old children during the National Oral Health Survey in 2005–2006. Dental caries assessments were carried out using World Health Organisation (WHO) criteria (1997). Weight status was assessed with body mass index according to WHO growth reference. A multivariable logistic regression model was applied to investigate the effect of dental caries and sociodemographic variables on the children’s weight status.
Results
Caries prevalence was 96.8 % in primary and 39.7 % in permanent teeth, and caries experience was 8.4 dmft and 0.6 DMFT. Of the children, 17.8 % were underweight, 73.0 % had normalweight, 6.0 % were overweight and 3.2 % were obese. Girls had a lower risk of being underweight than boys odds ratios (OR) 0.70, confidence interval (CI) 0.55–0.88. Children living in rural areas and with no television at home were more likely to be underweight (OR 1.36, CI 1.07–1.72; OR 1.37, CI 1.07–1.76, respectively). Fewer primary and permanent teeth were risk factors for being underweight (OR 0.93, CI 0.92–0.95; OR 0.90, CI 0.89–0.94, respectively).
Conclusions
Underweight was associated stronger with demographic and socioeconomic conditions than with dental variables. However, underweight and dental caries are public health issues of high priority affecting children at an important phase of their development.
Clinical relevance
Definite conclusions upon an association between dental caries and weight status in high caries risk schoolchildren cannot be drawn.
