| Summary: | Objectives: To investigate the trajectory of maternal intake of sugar-sweetened beverages (SSB)
during the first five years of their child’s life and its effect on the child’s dental caries at five
years-of-age.
Methods: This is an ongoing prospective population-based birth cohort study in Adelaide,
Australia. Mothers completed questionnaires on their SSB intake, socioeconomic factors and
health behaviors at the birth of their child and at the ages of one, two and five years. Child dental
caries measured as decayed, missing, or filled tooth surfaces was collected by oral examination.
Maternal SSB intake was used to estimate the trajectory of SSB intake. The trajectories then
became the main exposure of the study.
Dental caries at age five years were the primary outcomes. Adjusted mean- and prevalence-ratios
were estimated for dental caries, controlling for confounders.
Results: 879 children had dental examinations at five years-of-age. Group-based trajectory
modeling identified three trajectories of maternal SSB intake: ‘Stable low’ (40.8%), ‘Moderate but
increasing’ (13.6%), and ‘High early’ trajectory (45.6%). Multivariable regression analysis found
children of mothers in the ‘High early’ and ‘Moderate but increasing’ groups to have greater
experience of dental caries (MR: 1.37 (95%CI 1.01-1.67), and 1.24 (95%CI 0.96-1.60) than those
in the ‘Stable low’ trajectory, respectively.
Conclusion: Maternal consumption of SSB during pregnancy and in the early postnatal period
influenced their offspring’s oral health. It is important to create a low-sugar environment from
early childhood. The results suggest that health promotion activities need to be delivered to
expecting women or soon after childbirth. |
