ABSTRACT

Introduction: Optimising bone health might reduce the burden of both fractures in childhood and fragility fractures in later life. A number of maternal dietary and non-dietary factors have been identified that might influence offspring bone health and represent targets for intervention.

Areas covered: This article will outline the accrual of bone mineral throughout the life course and how observational and intervention studies have shown that maternal diet, in particular maternal calcium and 25-hydroxyvitamin D [25(OH)D] status, and lifestyle are associated with offspring bone mineralization. Studies examining the effects of maternal micronutrient supplementation on offspring bone mineral density (BMD) will also be discussed.

Expert commentary: There is a wealth of observational evidence relating maternal diet to offspring BMD. However, high quality randomized controlled trials, such as the ongoing MAVIDOS study, are needed before these findings can be definitively translated into public health advice.

Article Highlights

  • Fractures are common in childhood and later adult life and represent a significant healthcare burden.

  • Birthweight has been associated with bone mineral density (BMD) in adulthood, and a number of studies have demonstrated associations between maternal dietary quality or components and lifestyle and offspring bone health.

  • Observational studies relating maternal calcium status to offspring bone health are inconclusive, and the few studies of calcium supplementation have not consistently demonstrated a positive effect on offspring BMD; one study in the Gambia has shown mixed long-term effects on maternal BMD and offspring growth.

  • Many observational studies have identified positive relationships between maternal 25-hydroxyvitamin D status and offspring BMD. The MAVIDOS randomized controlled trial of cholecalciferol supplementation in pregnancy demonstrated that maternal vitamin D supplementation led to greater offspring neonatal BMD amongst winter born infants.
