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.
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.
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.
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.
早发性白发(PHG)常令患者极为担忧,因为它被视为衰老加剧、身体虚弱、活力下降的标志,还可能导致自卑和心理疾病。其发病机制尚未完全明确,但遗传因素以及各种后天因素都与之相关。本研究旨在评估与早发性白发相关的各种流行病学和生化变量。
在印度北部一家三级护理医院进行了一项为期1年的横断面病例对照研究,包括120例患者和数量相等的对照组。记录各种流行病学变量并与对照组进行比较。测量病例组和对照组的血清铁蛋白、血清钙、血清维生素D、血清维生素B12、血脂谱(血脂)、甲状腺功能指标和空腹血糖,并进行比较。
与对照组相比,病例组中特应性素质、久坐不动的生活方式、家族史、吸烟史以及较高的感知压力值的比例明显更高。使用发油似乎能预防早发性白发。值得注意的是,病例组中血清钙、铁蛋白、维生素B12、高密度脂蛋白胆固醇和高、低密度脂蛋白胆固醇水平明显较低。
根据本研究,需要进行更大样本量的进一步研究,以确定这些变量的确切病因学意义,并制定各种预防和治疗目标,以预防和治疗早发性白发。
