HIGH PREVALENCE OF VITAMIN D DEFICIENCY AMONG PATIENTS WITH TYPE 2 DIABETES: A POPULATION-BASED CROSS-SECTIONAL STUDY IN NEW JERSEY

1:00 AM – 2:00 AM

Objective : The last National Health and Nutrition Exam Survey estimated 41% of United States population is Vitamin D deficient, leading to considerable interest in the role of Vitamin D. Recent reports link low Vitamin D levels with poorly controlled blood sugars and suggest Vitamin D is implicated in the homeostasis of glucose metabolism. Our aim was to investigate the prevalence of Vitamin D deficiency in an established Diabetic population as compared to the general U.S. population.


Methods : This cross-sectional study involved a chart review of a sample of 106 Type 2 Diabetes Mellitus patients with normal renal function seen at a New Jersey Endocrinology office in 2018. The data collected included age, race, gender, vitamin D level, and serum creatinine. Vitamin D deficiency was defined as serum 25-hydroxy vitamin D level below 30 ng/mL. Mean age of study was 63.9 with 52.8% Males and 47.2% Females. The data was analyzed with a chi squared test and significant p value < .05.


Results : A total of 102 out of 106 patients, 96.2% of the studied diabetic population, had low vitamin D levels. Highest percent of vitamin D deficiency was found in the Hispanic population (100%), followed by African Americans (97.7%), Asians (88.9%) and Caucasians (88.2%). Observed association did not differ by sex (96% Males, 96% Females). Statistical analysis revealed chi squared 136.2 and p value < .00001.


Discussion : Based on a well-defined population in New Jersey, we have shown that the prevalence of Vitamin D deficiency in Type 2 Diabetics is greater than 2.3 times that of the general population in the United States; this data is statistically significant. Highest prevalence is noted in Hispanic and African American populations.


Conclusion : This study shows the high burden of Vitamin D deficiency on type 2 Diabetics, who should have Vitamin D levels routinely checked, with appropriate repletion, to improve glycemic control.
