Relationship between Tooth Emergence and Height and Weight.

Relationship between primary tooth variables (quintiles of ‘number of paired teeth’ at age 15 months and ‘age at first tooth’) and height (cm)/weight (Kg) at 17 years of age, in 1362 males and 1615 females. In the case of height, β-coefficients represent mean change in height per quintile increase in number of paired teeth/month increase in age at first tooth. Due to the skewed nature of weight we used the natural logarithm in analyses. Beta-coefficients were back transformed so that the coefficients represent the ratio of geometric means (RGM) of weight per quintile increase in number of paired teeth/month increase in age at first tooth. Analyses were adjusted for age at dxa scan, age (in months) of dentition questionnaire completion, gestational age and stratified by gender. p(int) is the p-value from a gender interaction test. R2 reports the coefficient of determination (variance explained) by the model outlined above.
