Calcium and bone health in infants

Area of Science:

• Pediatrics
• Nutritional Science
• Bone Biology

Background:

• Infancy is a critical period for bone mass accretion, surpassing even adolescence.
• Nutrient deficiencies during infancy, especially in preterm infants, can lead to osteopenia, rickets, and fractures.
• Adequate calcium and bone status in infancy is vital for immediate calcium homeostasis and mineralization, and long-term peak bone mass potential.

Purpose of the Study:

• To highlight the importance of optimizing calcium and bone status during infancy.
• To discuss the factors influencing infant calcium requirements and bioavailability.
• To address practical strategies for ensuring adequate calcium intake in both term and preterm infants.

Main Methods:

• Review of physiological factors affecting infant calcium requirements.
• Analysis of calcium bioavailability from various dietary sources.
• Consideration of practical nutritional management for infants.

Main Results:

• Bone mass accretion in the first year of life is substantial, equaling or exceeding other life stages.
• Optimizing calcium intake supports immediate bone mineralization and calcium balance.
• Meeting calcium needs in infancy contributes to achieving genetic potential for peak bone mass.

Conclusions:

• Ensuring optimal calcium nutriture during infancy is essential for preventing bone disorders and establishing lifelong skeletal health.
• Understanding calcium physiology and dietary sources is key to meeting infant needs.
• Practical approaches are necessary to optimize calcium intake for all infants, including vulnerable preterm populations.
