Hypovitaminosis D Implicated in the Development of Stress, Metabolic Syndrome and Hepatic Steatosis among Health Science Undergraduates attending a Tertiary Care Institute in Tamil Nadu, India

Introduction: Vitamin D deficiency is prevalent worldwide and its association with stress has become an emerging problem. A collection of linked physiological, biochemical, clinical, and metabolic risk factors is known as the Metabolic Syndrome (MS). High stress level is found associated with vitamin D deficiency and features of metabolic syndrome symptoms.

Aim: To estimate the prevalence of vitamin D deficiency, perceived stress, metabolic syndrome and hepatic steatosis among health science Undergraduate (UG) students and also to evaluate the association of vitamin D with percieved stress score, calcium, phosphorus, components of metabolic syndrome and indicators of liver steatosis.

Materials and Methods: This cross-sectional study was conducted in SRM Medical College, Hospital and Research Centre, Chennai, India, from February 2022 to August 2022. A total of 80 health science UG students in the age group of 19-25 years were included. The parameters included Fasting plasma glucose, Triglycerides (TGL), High Density Lipoprotein Cholesterol (HDLC), Gamma-glutamyl Transferase (GGT), phosphorus, calcium, and a Perceived Stress Scale (PSS) score scale. Data were statistically analysed using Pearson’s correlation test and Receiver Operating Characteristic (ROC) curve was used to assess the relationship of vitamin D with stress, metabolic syndrome and liver steatosis.

Results: In the present study, majority 56 (70%) had vitamin D deficiency, 23 (28.75%) had insufficiency and 1 (1.25%) had sufficiency. An estimated 6 (7.5%) of students experienced low stress, 63 (78.75%) experienced moderate stress and 11 (13.75%) experienced high perceived stress. Indicators of metabolic syndrome occurred in 13 (16.25%) of the population. Nearly 6 (7.5%) of the participants displayed manifestation of fatty liver. A negative association was found between vitamin D with stress score, Body Mass Index (BMI), waist circumference, Blood Pressure (BP), phosphorus, fasting plasma glucose, TGL, HDLC, GGT, Fatty Liver Index (FLI) score.

Conclusion: In the present study, vitamin D deficiency was most prevalent (70%), followed by metabolic syndrome, high stress and hepatic steatosis. Vitamin D showed a negative correlation with stress score, BMI, waist circumference, BP, phosphorous, fasting plasma glucose, TGL, HDLC, GGT and FLI score.
