Background and Objectives: Vitamin D deficiency (VDD) is highly prevalent in both healthy population and patients with type 2 diabetes mellitus (T2DM) in Bangladesh. Data on Vitamin D status in nonresident Bangladeshi (NRB) individuals with T2DM are scarce. We conducted this study to compare the Vitamin D status between resident and NRBs. Materials and Methods: This cross-sectional study evaluated 234 patients with T2DM (109 resident Bangladeshis [RBs] and 125 NRBs) attending a specialized diabetes hospital in Cumilla city, Bangladesh, from July 2021 to February 2022. Serum 25(OH)D <20 ng/mL defined VDD. Results: The mean age of the study participants was 42.5 ± 9.4 years; the frequencies of obesity, hypertension, dyslipidemia, and uncontrolled diabetes (HbA1c ≥7%) were 79.1%, 45.7%, 93.6%, and 88.9%, respectively. The Middle East countries were the residing countries of most (92.8%) of the NRBs. Higher frequencies of smokers and dyslipidemia were observed among RBs. The body mass index and HbA1c were higher, and low-density lipoprotein cholesterol was lower among NRBs than RBs. In the study participants, the mean 25(OH)D level was 25.7 ± 10.2 ng/mL; 30.3%, 38.5%, and 31.2% of the study participants were sufficient, insufficient, and deficient in Vitamin D, respectively. RBs and NRBs had similar 25(OH)D levels (25.7 ± 11.9 vs. 25.8 ± 8.5 ng/mL, P = 0.948) and VDD status (36.7% vs. 26.4%, P = 0.124). Conclusion: Low Vitamin D is highly prevalent in both RBs and NRBs with T2DM though they have similar Vitamin D levels and comparable rates of VDD. Further studies are needed to determine the factors that influence Vitamin D status in our people.
