Association between Short Stature at Grade 1 and Permanent Teeth Caries at Grade 6 in Elementary School Children in...

Area of Science:

• Pediatric Health
• Oral Epidemiology
• Nutritional Science

Background:

• Short stature in children can indicate poor nutritional status.
• Previous research suggests a potential link between short stature and dental caries, but longitudinal data are limited.
• Understanding this association is crucial for early identification and intervention strategies.

Purpose of the Study:

• To investigate the longitudinal association between short stature in elementary school children and the development of dental caries.
• To determine if early-life short stature serves as a predictor for future dental caries.

Main Methods:

• A longitudinal study analyzed data from 3576 elementary school children in Adachi City, Tokyo, Japan.
• Height-for-age data from grade 1 and dental caries (DMFT) data from grade 6 were collected.
• Multivariable Poisson regression with robust standard error was used to examine the association, adjusting for confounders.

Main Results:

• Children identified with short stature at grade 1 exhibited a significantly higher number of decayed, missing, or filled permanent teeth (DMFT) by grade 6.
• The mean ratio of DMFT was 1.17 for children with height-for-age between -2.01 and -3.00 SD, and 2.18 for those with height-for-age below -3.00 SD.
• These results remained significant after adjusting for potential confounding factors.

Conclusions:

• Short stature in the early elementary school years may serve as a valuable marker for predicting the risk of future dental caries.
• The findings underscore the importance of monitoring growth alongside oral health in children.
• Further research could explore underlying mechanisms connecting nutritional status, growth, and dental health.
