Background: Considering the paramount significance of hair in life, greying hair at a young age can be extremely distressing. In addition, an incompletely understood aetiology and scarcity of treatment options make premature hair greying (PHG) noteworthy. Aims: We aimed to estimate the prevalence of PHG in medical college students from Rajasthan, India, and any sociodemographic and lifestyle correlates of PHG and to determine its effect on the quality of life (QOL). Patients and Methods: A cross-sectional study was conducted amongst 295 students of a medical college in western Rajasthan, India, under the age of 25 years. A scalp examination was done to count grey hair. All factors were investigated using structured, pre-validated questionnaires. Results: The prevalence of premature greying of hair was 41.4%. Sociodemographic factors such as older age, rural residence and positive family history were significantly associated with PHG. The number of meals, fruit consumption and irregularity of meals were the lifestyle factors associated with PHG. The QoL of 54.1% of students with grey hair was poor; males and rural residents were more affected. Conclusions: Premature greying of hair is a fairly prevalent condition in medical college students affecting their QoL. Factors such as family history, age, residence and eating habits may predispose students to PHG. [ABSTRACT FROM AUTHOR]

Background and Objectives: Greying of hair is a regular feature of chronological aging that occurs in all regions and races. Premature canities is defined as minimum of five grey hairs in a person less than 20 years in Whites, 25 years in Asians, and 30 years in Africans. Premature canities is a common yet incompletely understood dermatological entity. This study aims at finding any association between premature hair greying (PHG) and parameters like hemoglobin (Hb), ferritin and calcium levels as well as its clinical profile. Methodology: This was a hospital-based cross-sectional analytical study conducted in the Department of Dermatology and Venereology, Trivandrum over one and half years. The study population consisted of 40 cases and 40 controls. Severity assessment, calculation of body mass index, and estimation of hemoglobin, serum ferritin, calcium, Random blood sugar, Anti Thyroid Peroxidase antibody, T3, T4, and TSH were done. Results: The mean age of the 40 patients was 17.14 years and most patients had onset of greying between 16 and 20 years. The male to female ratio was 1.2:1. A positive family history with a paternal predominance was noted. Vertex was the most common site of onset (42.5%), diffuse pattern was the most common clinical pattern (47.5%) and 60% had involvement of mild grade. Fourteen patients (35%) had abnormal investigations reports, in terms of low ferritin levels in 7 (17.5%), low calcium in 4 (10%) and a low Hb levels in 3 (7.5%) patients. Six (15%) patients had raised Anti TPO values. The association of PHG with low ferritin and raised anti-TPO levels were statistically significant. Conclusion: Low serum ferritin and raised Anti TPO levels may have a role in premature hair greying. [ABSTRACT FROM AUTHOR]

Objective: To document the epidemiological, clinical characteristics, believed triggers and associated behaviour in hair greying. Design: A community based cross-sectional descriptive study was conducted in February 2020 following ethical approval and written informed consent from participants. All participants were clinically evaluated for hair greying, its pattern and location on the scalp. Socio-demographic data were documented. Data was entered and analyzed using the IBM statistics software version 22. Numerical and categorical variables are presented. Setting: The study was conducted at an urban market in Lagos, Nigeria. Participants: The study participants comprised 307 adult traders. Results: The mean age of the 307 participants studied was 42.7±12.8 years. The prevalence of hair greying was 47.6% (51% in males and 45.9% in females). The median (IQR) age of those with grey hair was 52 (44, 59) years. The prevalence of hair greying was 14.8% in those aged 30-34 years and 97.2% in those aged 60 years and above. The prevalence of premature greying was 17.7% and greying before friends and family members was reported at 19.9% and 13%, respectively. Grey hair was diffuse in 81.5%; localized to the frontal area of the scalp in 55.5%. Use of hair dye was noted in 15.8%. Conclusion: Hair greying is common in the study population. The age at onset is 30 years. Premature hair greying is uncommon in Nigeria. More epidemiological studies of hair greying especially of premature hair greying are needed. [ABSTRACT FROM AUTHOR]

The association of hair greying with metabolic syndrome is not well known, while association with obesity and coronary artery disease has been suggested. A cross-sectional study was conducted to identify an association between premature hair greying and metabolic risk factors. Of the 1,929 young healthy subjects (1,067 men and 862 women), 704 (36.4%) were categorized in the premature hair greying group. Waist circumference (means of non-premature hair greying vs. premature hair greying, 74.3 vs. 76.3 cm; p < 0.001), systolic (109.2 vs. 111.7 mmHg; p < 0.001) and diastolic (65.0 vs. 66.2 mmHg; p = 0.003) blood pressures, and fasting blood sugar (90.8 vs. 91.6 mg/ dl; p = 0.013) were higher and serum high-density lipoprotein cholesterol (68.1 vs 65.4 mg/dl; p < 0.001) was lower in premature hair greying group. Multivariate logistic regression analysis showed that metabolic risk factors ≥ 2 was independently associated with premature hair greying after controlling for confounding factors (odds ratio 1.725; p = 0.036). The present study revealed an association between premature hair greying and metabolic risk factors. [ABSTRACT FROM AUTHOR]

Background: Many researchers have been indicated that premature hair greying (PHG) may be associated with the multifactorial problem include genetic, trace elements deficiencies and some medical problems such as metabolic disorders. However, the risk factors for premature hair greying are not well known for young adult., Aim: This study aimed to determine the risk factors of hair greying in young adult., Methods: We conducted a cross-sectional study recruited 100 respondents of a college student at the Universitas Sumatera Utara (USU) with the inclusion criteria: male, less than 25 years old with hair greying and not have skin pigmentation disorders. The questionnaires about greying of hair status, family history of greying and history of family disease were collected by self-report., Results: The age of participants in this study was 20.09 ± 2.01 years (mean ± SD). The mean onset of PHG was 15.23 ± 3.52 years (range: 9 - 22 years). The family history of PHG was 39% with paternal in 262%; maternal in 10%% and both parents in 3%. There was a significant difference between several grey hairs with a family history of PHG P = 0.045. The family history with metabolic disorders; hypertension was 29%, obesity was 25%, and diabetes Mellitus (DM) was 15%. Limitations: Owing to the use of questionnaires, the possibility of recall bias exists. The young female was not evaluated in this study., Conclusion: The family history of PHG and onset of greying are important risk factors associated with PHG of a young adult., (Copyright: © 2019 Dwi Rita Anggraini, Lita Feriyawati, Hidayat Hidayat, Arlinda Sari Wahyuni.)
