Insights
Maternal calcium and vitamin D supplementation during lactation, and infant supplementation, significantly decrease infant bone-specific alkaline phosphatase (BAP). Fontanel size did not indicate infant calcium status.
Area of Science:
- Nutritional science
- Pediatric bone health
- Maternal-infant health
Context:
- Bone development is crucial in early life.
- Calcium and vitamin D are essential nutrients for skeletal health.
- Supplementation strategies during pregnancy, lactation, and infancy are explored.
Purpose:
- To evaluate the impact of calcium and vitamin D supplementation on infant bone development.
- To assess the effects of supplementation during different maternal and infant stages.
- To determine the relationship between supplementation and infant bone markers.
Summary:
- Maternal calcium and vitamin D intake during lactation and infant supplementation significantly reduced infant bone-specific alkaline phosphatase (BAP).
- Supplementation during pregnancy did not show a significant effect on infant BAP.
- Infant feeding methods did not significantly influence BAP levels.
- Fontanel anterior (FA) size in infants under 42 days showed a negative correlation with BAP, but FA size did not reliably indicate infant calcium status.
Impact:
- Provides evidence for optimal timing of calcium and vitamin D supplementation for infant bone health.
- Highlights the importance of maternal supplementation during lactation and direct infant supplementation.
- Suggests that fontanel size may not be a reliable indicator of calcium status in infants.
Objective:
To investigate the effect of calcium and vitamin D supplementation during pregnancy, lactation and infants on bone development of infant.
Methods:
1176 health infants aged 42-365 days and their mothers were recruited as subjects at Pediatric Department in Beijing Obstetrics and Gynecology Hospital during November 2006 to January 2008. Retrospective questionnaire was asked about calcium and vitamin D supplementation during pregnancy, lactation and infant. Blood bone-specific alkaline (BAD) and fontanel anterior (FA) of infant were measured. Chi2 test and logistic regression were used to analyze the research data.
Results:
The chi2 test result showed that maternal supplementation with Ca and vitamin D during breastfeeding could decrease infant BAP significantly (P = 0.018), while supplementation during pregnancy could not (P = 0.154). The logistic regression result showed that infant supplementation with Ca and Vitamin D could decrease infant BAP significantly (P = 0.000), while infant feeding methods could not (P > 0.05). The FA size of infants aged < or =42 days had significant negative relationship with BAP (P = 0.017), and no relationship with Ca and vitmin D supplementation during pregnancy.
Conclusion:
Supplementation with Ca and vitamin D of mother during lactation and infant could significantly decrease infant BAD. The FA size could not indicate the infant calcium status.

Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
