In a recent study, scientists from Texas have been comparing the prevalence of vitamin D deficiency in obese and non-overweight children and examining the relationship between vitamin D status and markers of abnormal glucose metabolism and blood pressure.
Data on blood pressure, diet, vitamin D levels and the results of blood tests designed to detect diabetes were recorded for 411 obese children aged 6–16 years at an obesity referral clinic. Vitamin D levels were also obtained for 87 non-overweight children for comparison.
When the data was analysed, the scientists found that a shocking 92% of the obese children had a vitamin D level below the optimal 75nmol/litre and 50% were below 50nmol/litre. Among the non-overweight children, vitamin D deficiency was less prevalent, but still significant, with 68% recording levels below 75nmol/litre, and 22% below 50nmol/litre. What’s more, the blood test results showed that low vitamin D levels were significantly associated with risk factors for type II diabetes, such as insulin resistance and high blood sugar levels.
