Low Vitamin D Persists Year-Round in Northern Britain
Screening data from a UK clinical trial found low vitamin D levels in 55% of older patients and 72% of ethnic patients, with little variation despite summer months.
Clinical Report: Low Vitamin D Persists Year-Round in Northern Britain
Overview
A study found that over half of older patients and nearly three-quarters of ethnic patients in northern Britain had vitamin D insufficiency or deficiency, with little seasonal variation.
Background
Vitamin D insufficiency is a significant public health concern, particularly among older adults and ethnic minorities who may have limited sun exposure. Understanding the prevalence of vitamin D deficiency is crucial.

Key Findings
55% of older patients had serum 25-hydroxyvitamin D levels below 50 nmol/L.
72% of ethnic patients had serum 25-hydroxyvitamin D levels below 50 nmol/L.
Vitamin D insufficiency or deficiency persisted across all seasons, with no significant decline during summer months.
Among older patients, the prevalence of insufficiency during June through August was 56%.
Ethnic patients maintained high rates of insufficiency throughout winter, spring, and summer.
Clinical Implications
Clinicians should be aware that vitamin D status may not improve in summer for high-risk groups, such as older adults and ethnic minorities. Regular screening and appropriate supplementation strategies may be necessary to address persistent vitamin D insufficiency in these populations.
Conclusion
The study reports high rates of vitamin D insufficiency among high-risk groups in northern Britain.
A new international consensus framework standardizes how disease severity and relapse are defined, addressing inconsistencies that have complicated clinical trials and treatment decisions.
