Abstract
The purpose of this study was to evaluate the age of the mother as a risk factor in caries incidence in the three year old children. The subjects were 870 pairs of a mother and her first child. Caries incidence in children was examined at three and a half years of age.
The factors analyzed with logistic model analysis were as follows: the age of the mother at the birth of her first child: 22 years or less,23 years or more; frequency of between meals: 4 times or more per day,3 times,2 times,1 time or none; regularity of between meals: irregular, regular; tooth brushing by mother: none or sometimes, every day; living with grandparent(s): yes, no; working of mother: yes, no.
The results were as follows.
The risk factors showing significant correlation with the caries incidence were the age of the mother being 22 years or less (ratio of odds: 2.451, CI95: 1.623-3.702, p<0.001); frequency of between meals being 4 times or more (ratio of odds: 2.638, CI95: 1.314-5.296, p=0.006) and living with grandparent (s) (ratio of odds: 1.352, CI95: 1.024-1.786, p=0.034).
This study suggests that with the age of the mother of 22 years or less there a risk factor of caries incidence in 3 year old children.
