This project examined the relative significance of dietary sugars, toothbrushing frequency and social class as predictors of caries experience (caries vs. no caries) among 1,450 British pre–school children who took part in the National Diet and Nutrition Survey. This cross–sectional survey was based on a representative sample of children aged 1.5–4.5 years studied in 1992/3. Children were classified into four groups according to social class and toothbrushing habit. Diet/caries associations were examined for biscuits and cakes, sugar confectionery, chocolate confectionery and soft drinks, and the percentage of energy from non–milk extrinsic sugars, using data on amount and frequency of consumption from 4–day weighed dietary records. In stepwise logistic regressions, the strength of the association between social class and caries experience was twice that between toothbrushing and caries, and nearly three times that between sugar confectionery and caries (other dietary variables were not significant). The association of caries with sugar confectionery (both in amount and frequency) was only present among children whose teeth were brushed less than twice a day. Toothbrushing frequency appeared to have a stronger impact on caries prevention in non–manual compared with manual children. Household expenditure on confectionery was associated with caries only among children from the manual group. The findings suggest the hypothesis that regular brushing (twice a day) with a fluoride toothpaste may have greater impact on caries in young children than restricting sugary foods.
Voluntary and involuntary smoking influence general health. Links between voluntary smoking and oral health are confirmed for periodontal diseases and oral cancer/precancer. Since recent reports have suggested an association between parental smoking and caries experience in young children, this study aimed to explore varying patterns of parental smoking, adjusted for social class, with caries prevalence, using data derived from the UK National Diet and Nutrition Survey (1995). Data analysis was confined to 749 children aged 3.0–4.5 years, to avoid confounding effects of unerupted teeth. Bivariate analysis indicated that the prevalence of maternal rather than paternal smoking was significantly related to caries and substantially attenuated social class differences. The reported number of cigarettes smoked was not important. To compensate for the association between social class and maternal smoking, data were dichotomised by social class (manual/non–manual). With caries prevalence as the dependent variable, logistic regression analysis recorded maternal smoking as a significant independent variable in each case, with odds ratios of 1.55/1.96, respectively. The process was repeated for the combined dataset, using the more extensive (six) social class categories. This further analysis yielded an odds ratio for maternal smoking of 1.54 compared with 1.46 for social class. Nutrition status (as growth parameters) and dietary intake (as household spending on confectionery) were not significant independent variables in these equations. The rationale for these findings is discussed. Further research is required to determine mechanisms underlying these observations. It is concluded that maternal smoking is a significant factor to be considered as an additional risk indicator beyond social class when predicting caries risk in young children.
This paper aims to describe the sociocultural context of areca nut use through exploring people's norms and values and the meaning underlying a wide range of different practices. A historical review is followed by an examination of more recent evidence, including quantitative and qualitative research conducted in the United Kingdom. It is concluded that some reports involving the various uses of areca nut and the conclusions drawn are confusing and that future studies need to be more explicit. While a sound scientific background is required, important sociocultural and religious issues around areca nut use must also be understood if health promotion initiatives are to be considered.
