Basic research design: Cross-sectional study analysing data from the National Child Measurement Programme (N=2427) and the Local Dental Health Survey (N=1425). The association of deprivation with weight status and caries was determined at individual and area level, using ANOVA and Poisson models. The overall spatial clustering was assessed using a modified version of the Global Moran's I, while clusters were located through Local Indicators of Spatial Association. Spatial autocorrelation was assessed using the variograms of the raw values. Log-linear Poisson models were fitted to assess the significance of neighbourhood characteristics on overweight/obesity and caries distribution. Results: At an individual level, deprivation was not associated with BMI z-scores but was a significant predictor of caries (p<0.05). However, at area level, deprivation related to the rates of both conditions. A significant positive autocorrelation was observed across neighbourhoods for caries. The variograms suggested spatial autocorrelations up to 2.5 km and 3 km for overweight/obesity and caries, respectively. Among several neighbourhood characteristics, the proportion of people on benefits was found to be a significant predictor of caries rates. Conclusions: Our results underline the importance of considering geographic location and characteristics of the broader environment when developing strategies to target obesity and caries.||ISSN:||0265-539X||DOI:||10.1922/CDH_4214Paisi07||Rights:||© Dennis Barber||Type:||Article||Affiliation :||University of Plymouth
