Abstract

BACKGROUND

There are racial differences in the prevalence and types of androgenetic alopecia (AGA). The prevalence of AGA has been studied in Caucasians and in some Asian people. In China, although there have been some epidemiological studies carried out in single cities or regions, no multicentre population-based study has been reported.

OBJECTIVES

To study the prevalence and types of AGA in China and to compare the results with those previously reported in Caucasians and in other Asian people.

METHODS

A community-based study was carried out in six cities of China. Subjects were interviewed face-to-face and completed questionnaires. The degree of AGA was classified according to the Norwood and Ludwig classifications.

RESULTS

In total 17 886 subjects were interviewed and 15 257 completed the questionnaires. In men, the overall prevalence of AGA was 21.3%, with 2.8% in men aged 18-29 years, 13.3% in those aged 30-39 years, 21.4% in those aged 40-49 years, 31.9% in those aged 50-59 years, 36.2% in those aged 60-69 years and 41.4% in those aged 70 years and over. The most common type was frontal and vertex hair loss. A small number of subjects (3.7%) showed 'female pattern' hair loss. In women, the prevalence of AGA was 6.0%, with 1.3% in women aged 18-29 years, 2.3% in those aged 30-39 years, 5.4% in those aged 40-49 years, 7.5% in those aged 50-59 years, 10.3% in those aged 60-69 years and 11.8% in those aged 70 years and over. Ludwig grade I was the most common type. The prevalence of AGA varied between cities. A positive family history was present in 29.7% of men and 19.2% of women with AGA.

CONCLUSIONS

The prevalence of AGA in Chinese men and women was lower than in Caucasians and similar to that in Koreans.

摘要

背景

雄激素性脱发（AGA）的患病率和类型存在种族差异。AGA 的患病率已在白种人和一些亚洲人群中进行了研究。在中国，虽然已经在单个城市或地区进行了一些流行病学研究，但尚未报告多中心基于人群的研究。

目的

研究中国 AGA 的患病率和类型，并将结果与白种人和其他亚洲人群的研究结果进行比较。

方法

在中国六个城市进行了一项基于社区的研究。通过面对面访谈和问卷调查对受试者进行了调查。AGA 的严重程度根据 Norwood 和 Ludwig 分类进行分类。

结果

共访谈了 17886 名受试者，其中 15257 名完成了问卷。男性中 AGA 的总体患病率为 21.3%，18-29 岁男性为 2.8%，30-39 岁男性为 13.3%，40-49 岁男性为 21.4%，50-59 岁男性为 31.9%，60-69 岁男性为 36.2%，70 岁及以上男性为 41.4%。最常见的类型是额部和顶部头发稀疏。少数受试者（3.7%）表现为“女性型”脱发。女性 AGA 的患病率为 6.0%，18-29 岁女性为 1.3%，30-39 岁女性为 2.3%，40-49 岁女性为 5.4%，50-59 岁女性为 7.5%，60-69 岁女性为 10.3%，70 岁及以上女性为 11.8%。Ludwig 分级 I 是最常见的类型。AGA 的患病率在不同城市之间存在差异。有 AGA 的男性中有 29.7%和女性中有 19.2%有阳性家族史。
