Statistical Information
- Rising Burden of Anemia Increases Demand for Vitamin B Testing: According to the World Health Organization (WHO), 1.92 billion people worldwide were affected by anemia in 2021, representing approximately 23.9% of the global population. Vitamin B12 and folate deficiencies are recognized nutritional causes of megaloblastic anemia, increasing the need for laboratory testing to identify the underlying deficiency.
- Older Adults Are a High-Risk Population for Vitamin B12 Testing: The U.S. National Institutes of Health (NIH) reports that 3.6% of U.S. adults aged 19 years and older have vitamin B12 deficiency, while 12.5% have vitamin B12 insufficiency. Older adults are among the highest-risk groups because reduced stomach acid and gastrointestinal disorders impair vitamin B12 absorption, increasing physician recommendations for routine screening.
- Vitamin B12 Deficiency Increases with Age: A large population study involving 3,511 adults aged 65 years and above found that vitamin B12 deficiency increased from approximately 1 in 20 people (5%) among those aged 65–74 years to 1 in 10 (10% or more) among adults aged 75 years and older. These findings support higher diagnostic testing rates in elderly populations.
- Fortification Policies Increased Consumer Awareness of Vitamin B Status: CDC researchers reported that following mandatory folic acid fortification in the United States, the prevalence of marginal vitamin B12 deficiency decreased from 25.1% to 20.7% among older adults, while vitamin B12 deficiency remained closely monitored through laboratory testing programs.
- Atrophic Gastritis Increases Testing Need in Elderly Patients: NIH estimates that 8%–9% of adults aged 65 years and older have atrophic gastritis compared with about 2% of the general population. This condition significantly reduces vitamin B12 absorption and increases physician-ordered diagnostic testing.
- Vitamin B12 Stores Can Delay Symptoms for Years: The NIH states that the human body stores approximately 1–5 mg of vitamin B12, equivalent to roughly 1,000–2,000 times the average daily intake. As a result, deficiency symptoms may take several years to appear, reinforcing the importance of laboratory screening
- Average Daily Vitamin B12 Intake Exceeds Recommended Levels: NHANES 2017–2020 data show that average vitamin B12 intake from foods was 5.84 mcg/day for men and 3.69 mcg/day for women, both above the recommended 2.4 mcg/day for adults. Despite this, deficiency persists because absorption disorders remain common.
- Long-Term Acid Suppression Raises Vitamin B12 Deficiency Risk: A large PubMed study found that patients receiving proton pump inhibitors (PPIs) for two years or longer had a 65% higher risk of vitamin B12 deficiency (OR 1.65; 95% CI 1.58–1.73). Higher daily doses increased the risk further to OR 1.95.
- Meta-Analysis Included More Than 30,000 Participants: A systematic review and meta-analysis covering 25 clinical studies involving 2,852 PPI users and 28,070 non-users found that PPI users had a 42% higher likelihood of vitamin B12 deficiency (OR 1.42).
