Background:

• The vitamin B12 market in Sweden experienced a threefold increase between 1991 and 1995.
• Primary healthcare providers accounted for the majority (60%) of vitamin B12 prescriptions.

Purpose of the Study:

• To investigate the attitudes, values, and knowledge of Swedish family physicians/general practitioners regarding vitamin B12 deficiency management.

• A response rate of 74% was achieved, with dropout analysis confirming sample representativeness.

Main Results:

• Analysis of physician responses supported the hypothesis linking market growth to increased awareness.
• Physicians' understanding of biochemical, pathophysiological, and social aspects of vitamin B12 deficiency appears to have risen.
• The study suggests a correlation between enhanced primary care awareness and the expanding vitamin B12 market.

Conclusions:

• Increased awareness among primary healthcare providers is a likely driver for the significant growth in the Swedish vitamin B12 market.
• Further research into physician education and patient outcomes related to vitamin B12 deficiency is warranted.
