Abstract
BACKGROUND: Premature hair graying (PHG) is often a matter of great concern for patients as it is viewed as a sign of increasing age, debility, decreasing vigor, and may lead to low self-esteem and psychological morbidity. Its etiopathogenesis is not completely understood but genetic, and various acquired factors have been implicated. The present study was undertaken to evaluate various epidemiological and biochemical variables associated with PHG. MATERIALS AND METHODS: A cross-sectional case-control study was conducted at a tertiary care hospital in North India for 1 year which comprised 120 patients and equal number of controls. Various epidemiological variables were recorded and compared to controls. Serum ferritin, serum calcium, serum Vitamin D, serum Vitamin B12, lipid profile, thyroid profile, and fasting blood sugar were measured and compared among cases and controls. RESULTS: Significantly higher proportion of cases had atopic diathesis, sedentary lifestyle, family history, history of smoking, and higher perceived stress values as compared to controls. Hair oiling seemed to protect against premature graying. Significantly, lower levels of serum calcium, ferritin, Vitamin B12, high-density lipoprotein-cholesterol, and high low-density lipoprotein-cholesterol were observed among cases. CONCLUSION: In the light of the present study, further studies with larger sample size are required to establish the definite etiological significance of these variables and formulate various preventive and therapeutic targets to prevent and treat PHG.
