The prevalence and severity of Vitamin D deficiency are more commonly revealed among Indian females compared to males. Subjects and Methods: The study subjects comprised 198 female students of a nursing college located in Northeast India who were attending the gynecology outpatient department of a tertiary care center. Study participants were invited to respond to online queries related to Vitamin D deficiency and associated sociocultural practices. Among them, 126 students who had volunteered, 25 OH Vitamin D total levels were estimated by enzyme-linked fluorescent assay method along with linked blood parameters.
