Abstract
BackgroundMaternal nutrition status during pregnancy may affect fetal tooth development, formation, and mineralization, and may affect dental caries susceptibility in children. We investigated the association between maternal intake of dairy products and calcium during pregnancy and the risk of childhood dental caries.MethodsSubjects were 315 Japanese mother-child pairs. Data on maternal intake during pregnancy were assessed through a diet history questionnaire. Outcome data was collected at 41–50 months of age. Children were classified as having dental caries if one or more primary teeth had decayed or been filled.ResultsHigher maternal cheese intake during pregnancy was significantly inversely associated with the risk of dental caries in children, showing a clear inverse dose–response relationship; the adjusted odds ratio (OR) in comparison of the highest tertile with the lowest was 0.37 (95 % confidence interval [CI]: 0.17-0.76, P for trend = 0.01). The inverse associations between maternal intake of total dairy products, yogurt, and calcium during pregnancy and the risk of childhood dental caries were of borderline significance: the adjusted ORs for the highest tertile of total dairy products, yogurt, and calcium were 0.51 (95 % CI: 0.23-1.09, P for trend = 0.07), 0.51 (95 % CI: 0.23-1.10, P for trend = 0.07), and 0.50 (95 % CI: 0.23-1.07, P for trend = 0.08), respectively. There was no evident relationship between maternal milk intake and the risk of childhood dental caries.ConclusionThese data suggested that high intake of maternal cheese during pregnancy may reduce the risk of childhood dental caries.
Highlights
Maternal nutrition status during pregnancy may affect fetal tooth development, formation, and mineralization, and may affect dental caries susceptibility in children
The purpose of this prospective study was to investigate the association between maternal intake of dairy products and calcium during pregnancy and the risk of dental caries in young Japanese children, using data from the Osaka Maternal and Child Health Study (OMCHS)
Compared with the 687 children who were excluded from the present analysis, the 315 study subjects were more likely to have older mothers, report higher family income, have parents with relatively high educational levels, and have high intake levels of yogurt and calcium, while they were less likely to have been exposed to maternal smoking during pregnancy (Table 1)
Summary
Maternal nutrition status during pregnancy may affect fetal tooth development, formation, and mineralization, and may affect dental caries susceptibility in children. A follow-up study of a randomized controlled trial in Argentina showed that maternal calcium supplementation during pregnancy was significantly inversely associated with dental caries in children at 12 years of age [9]. In another longitudinal study in Thailand, the incremental risk of caries between 9 and 12 months of age was lower among children whose mothers had received calcium supplements during pregnancy [10]. The purpose of this prospective study was to investigate the association between maternal intake of dairy products and calcium during pregnancy and the risk of dental caries in young Japanese children, using data from the Osaka Maternal and Child Health Study (OMCHS)
