| Outline of Final Research Achievements |
In this population based retrospective cohort study of 76920 children born between 2004 and 2010 in Kobe City, prevalence of household smoking was 55.3% (n=42525), and 6.8% (n=5268) had evidence of exposure to tobacco smoke. A total of 12729 incidents of dental caries were observed and most were decayed teeth (3 year follow-up rate 91.9%). The risk of caries at age 3 years was 14.0% (no smoker in family), 20.0% (smoking in household but without evidence of exposure to tobacco smoke), and 27.6% (exposure to tobacco smoke). The propensity score adjusted hazard ratios of the two exposure groups compared with having no smoker in the family were 1.46 (95% confidence interval 1.40 to 1.52) and 2.14 (1.99 to 2.29), respectively. The propensity score adjusted hazard ratio between maternal smoking during pregnancy and having no smoker in the family was 1.10 (0.97 to 1.25).
