Hair pigmentation is one of the most conspicuous phenotypes in humans ranging from black, brown, and blonde to red. Premature graying of hair occurs more commonly without any underlying pathology but is said to be inherited in autosomal dominant pattern. Premature graying has been shown to be associated with a few of the autoimmune disorders. A role for environmental factors and nutritional deficiencies has also been postulated. However, to date the exact etiology of premature graying has not been established.
The objective of our study was to conduct an epidemiological and investigative study of premature graying of hair in higher secondary and pre-university school children of the semi-urban area.
A total of 35 cases and controls were investigated for various parameter such as Hemoglobin, total iron binding capacity, serum ferritin (S. Ferritin), serum calcium (S. Ca), serum iron (S. Iron), vitamin B12, and vitamin D3 after taking informed consent. Epidemiological and investigations correlation was established using the Chi-square and Mann Whitney test and P < 0.05 values were considered significant.
Among the various laboratory parameters S. Ca, S. Ferritin and vitamin D3 were low in patients with premature graying of hair. There was significant high number of vitamin D3 deficient and insufficient among the cases compared to the controls.
According to our study S. Ca, S. Ferritin, vitamin D3 may play a role in premature graying of hair in our society.
头发色素沉着是人类最显著的表型之一,从黑色、棕色、金色到红色。头发过早变白在没有任何潜在病理状况的情况下更为常见,但据说呈常染色体显性模式遗传。头发过早变白已被证明与一些自身免疫性疾病有关。环境因素和营养缺乏也被认为有一定作用。然而,迄今为止,头发过早变白的确切病因尚未明确。
我们研究的目的是对半城市地区高中和大学预科学校儿童头发过早变白进行流行病学和调查研究。
在获得知情同意后,对35例病例和对照进行了各种参数的调查,如血红蛋白、总铁结合力、血清铁蛋白(S. 铁蛋白)、血清钙(S. 钙)、血清铁(S. 铁)、维生素B12和维生素D3。使用卡方检验和曼-惠特尼检验建立流行病学和调查相关性,P < 0.05的值被认为具有统计学意义。
在各种实验室参数中,头发过早变白患者的S. 钙、S. 铁蛋白和维生素D3水平较低。与对照组相比,病例组中维生素D3缺乏和不足的人数显著更多。
根据我们的研究,S. 钙、S. 铁蛋白、维生素D3可能在我们社会中头发过早变白中起作用。
