“…2,[19][20][21] In a previous study, a female pattern was observed in 11.1% of Korean males with AGA, which is higher than that found in white males. 20 In the current study, a female pattern (type F) accounted for approximately 37% in men, which was more frequent than expected.…”

“…The prevalence of male pattern baldness accounted for 14.1% in Korean males and 38.5% in Thai males; in white males, it accounted for 46.0%. 3,20,21 In addition, Japanese men develop AGA approximately one decade later than whites, and the prevalence is 1.4-fold lower in each decade of life. 22 Therefore, Asian men with PHL are disposed to have different aspects from those of whites.…”

“…Following that study we recognized that a significant proportion of Australian men developed frontal recession as their predominant pattern of hair loss and modified our grading scale to include stage 4. In comparison to previous prevalence studies from the UK, US, Korea, and Thailand (Norwood, 1975;Venning and Dawber, 1988;Birch et al, 2001;Norwood, 2001;Paik et al, 2001;Pathomvanich et al, 2002), our study recruited subjects from a standard study population in Maryborough. The recruitment of our study was similar to the studies done in Norway (Demuro-Mercon et al, 2000) and Singapore (Tang et al, 2000), but the two studies reported only the epidemiology of MPHL.…”

Maryborough, in central Victoria has an approximate population of 8000 and census data is well matched for Australia overall. Australia has compulsory voting and registration on the electoral roll. To determine the age-related prevalence of balding among men and women in Maryborough we conducted a postal survey of 5000 men and women aged 20 or older, and 427 were invited to attend for examination. Additional data was collected on dandruff, presence of gray hair. Supplementary questionnaires were sent to 340 children aged 5-9, attending a coeducational primary school. 1456 adults (34.1%) responded to the questionnaire. 396 attended for examination. The prevalence of androgenetic alopecia (AGA) increased with advancing age. 98.6% of men had bitemporal recession and severity was significantly associated with vertex and mid-frontal hair loss (p <0.01) but not age (p = 0.06). In all, 64.4% of women had bitemporal hair loss, and similar to men there was a significant association with mid-frontal hair loss (p =0.042) but not age (p =0.467). One hundred and forty children with completed questionnaires were examined. All 72 females and 68 males were assessed as stage 1 on the mid-line part and with no bitemporal recession (frequency stage 1 = 100%, 95% CI (confidence interval) 97.4%-100%). A significant but weak positive association existed between presence of gray hair and history of dandruff (p<0.01). The prevalence of mid-frontal hair loss increases with age and affects 57% of women and 73.5% of men aged 80 and over.

“…Während etwa 50% der Männer europäischer Abstammung bis zum Alter von 50 Jahren in unterschiedlichem Ausmaß betroffen sind [15,24],scheint die Inzidenz der androgenetischen Alopezie bei asiatischen und afrikanischen Männern geringer zu sein [52,60]. Bei Frauen ist die Inzidenz generell niedriger als bei Männern.…”

Androgenetische Alopezie

Androgenetic alopecia is the most common type of hair loss in men and women. The disorder represents a quantitative phenotype with an underlying genetic disposition. So far none of the causative genes have been identified. Under the influence of androgens there is a shortening of the anagen phase as well as a reduction of the cellular hair matrix volume in the involved scalp area. This results in the transformation of thick terminal hair follicles into thin vellus-like hair follicles. Clinically, patients present with an alopecia that follows a defined pattern (pattern baldness) and progresses continuously but in varying degrees. In advanced cases, men may develop baldness with remaining hair exclusively in the temporal and occipital regions. Women are prone to exhibit a more diffuse type of hair loss with pronounced thinning in the parietal region. Whereas the diagnosis of androgenetic alopecia is easy, its treatment is often difficult. The physician is commonly confronted with high patients' expectations regarding hair regrowth. Today, with minoxidil and finasteride, effective therapies are available which can lead to cessation of hair loss. The identification of underlying genes will make a more specific therapy easier to achieve.
