Vitamin D: Australian dietitian's knowledge and practices.

Area of Science:

• Nutrition Science
• Public Health

Background:

• Vitamin D (VitD) is crucial for bone health and immune function.
• Dietitians play a key role in advising on nutrient intake and supplementation.
• Understanding current dietitian knowledge and practices is essential for optimizing VitD recommendations.

Purpose of the Study:

• To assess dietitians' knowledge and practices concerning vitamin D (VitD).
• To identify gaps in understanding regarding VitD intake, sources, supplementation, and disease impact.

Main Methods:

• An online survey was distributed to Australian dietitians in April 2015.
• The survey collected data on knowledge and current practices related to VitD.
• Descriptive statistics were employed for data analysis.

Main Results:

• Dietitians demonstrated strong knowledge of dietary VitD sources and its physiological roles.
• Inconsistencies were observed in knowledge regarding optimal VitD supplement dosages for deficiency prevention and treatment.
• Uncertainty exists among dietitians concerning evidence-based sun exposure guidelines for VitD synthesis.

Conclusions:

• Dietitians possess foundational knowledge for advising on VitD but require enhanced confidence and clarity.
• There is a clear need for updated, accessible guidelines on VitD management for dietitians.
• Professional development and standardized protocols can improve dietitian capacity to provide accurate VitD advice.
