This health problem is characterized by increased urinary albumin excretion, leading to decreased glomerular filtration rate and renal failure. In this regard, previous investigations have revealed the possibility of a relationship between vitamin D deficiency and diabetic nephropathy. The present study assessed the relationship between vitamin D deficiency and albuminuria in patients with type 2 diabetes.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This study was conducted with 200 participants with type 2 diabetes mellitus from December 2019 to January 2021. The patients\u2019 25-hydroxyvitamin D (25OHD) serum level and urinary albumin-to-creatinine ratio (UACR) were measured concurrently. Afterward, the subjects were divided into three groups based on their albuminuria level. Finally, 25OHD serum level and other clinical characteristics were compared among these albuminuria groups, and the relation between albuminuria level and 25OHD was analyzed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The prevalence of vitamin D deficiency in macroalbuminuric patients (UACR\u2265300\u2009mg\/g) was 61.8%, and in microalbuminuric (30\u2009\u2264\u2009UACR&lt;\u2009300\u2009mg\/g) and normoalbuminuric groups (UACR&lt;\u200930\u2009mg\/g) was 33.3% and 24%, respectively.
