Researchers from the University of Surrey analyzed the vitamin D status of 6,433 middle-aged South Asian individuals from the United Kingdom and found that 20% of South Asians had a severe Vitamin D deficiency. Vitamin D deficiency is often associated with other health conditions such as hypertension, cardiovascular disease, cancer, respiratory infections, and osteomalacia. The research team found that geography and Body Mass Index (BMI) were two possible factors that could impact Vitamin D levels. South Asians in Scotland, Wales, and Northern England had slightly lower Vitamin D levels than those living in London and the South East. South Asian individuals classified as overweight by their BMI had a 32% higher chance of Vitamin D deficiency, while those classified as obese had a 51% higher chance of Vitamin D deficiency. Researchers hope that identifying this vulnerable population will lead to targeted public health campaigns to mitigate this health disparity.
