What Lithuanian First-Graders Eat: Results of a 15-Year Semi-Longitudinal, Cross-Sectional Surveillance Study.

This article presents the dietary habits of Lithuanian first-grade (7-8-year-old) students over a 15-year surveillance period to understand the trends and changes in their nutrition patterns. The presented data were collected from three study rounds of the Lithuanian Growth Surveillance Study conducted between 2008 and 2023, with a total sample of 11,594 first-grade students from all 10 counties of Lithuania. The main findings reveal significant shifts in breakfast consumption, with an increase in daily breakfast intake observed over the surveillance period.

Heritability estimates of dental arch parameters in Lithuanian twins.

Background: The genetic influence on dental arch morphology may be country-specific, thus it is reasonable to check the estimates of genetics across different populations. The purpose of this study was to evaluate the heredity of dental arch morphology in the sample of Lithuanian twins with accurate zygosity determination.

Material And Methods: The study sample consisted of digital dental models of 40 monozygotic (MZ) and 32 dizygotic (DZ) twin pairs.
