Sensitive skin is a complex dermatological condition, defined by abnormal sensory symptoms. The aim of this epidemiological survey was to assess the prevalence of sensitive skin and collect data on sensitive skin in the US population.
A phone survey was conducted in the USA by a poll institute in 2007. A sample was drawn from a representative national cohort of the American population at least 18years of age through the quota method. Data on demographic characteristics, environmental and climatic factors, skin characteristics, dermatological disorders, cosmetics use, and visits to the dermatologist were collected.
Of 994 subjects who answered (495 men and 499 women), 44.6% declared having "sensitive" or "very sensitive" skin. Women were more concerned than men (50.9% vs. 38.2%, P<0.0001). There was no significant difference related to geographic localization, age, or ethnic distribution. Subjects with sensitive skin had mainly dry (34.5%) or mixed skin (35.7%), fair phototypes, dermatological disorders, higher skin reactivity to cosmetics and various environmental factors in comparison with subjects who stated having only a "slightly" sensitive or not sensitive skin. The dermatologist had a strong influence on subjects with "sensitive" or "very sensitive" skin through the prescription of skin care products.
This study, based on a representative sample of the American population, reveals a high prevalence of sensitive skin in the USA. Sensitive skin is mainly associated with dry skin, fair phototype, reactivity to climatic and environmental factors, and cosmetics. American dermatologists seem largely involved in the care of this condition.
敏感皮肤是一种复杂的皮肤科疾病，其特征为异常的感觉症状。本项流行病学调查旨在评估敏感皮肤在美国人群中的患病率，并收集相关数据。
2007 年，一家调查机构在美国进行了电话调查。采用配额法，从具有代表性的美国人群中抽取至少 18 岁的样本。收集了人口统计学特征、环境和气候因素、皮肤特征、皮肤病、化妆品使用情况以及皮肤科就诊情况的数据。
在 994 名回答问题的受试者中（495 名男性和 499 名女性），44.6%的人表示自己的皮肤“敏感”或“非常敏感”。女性比男性更关注敏感皮肤（50.9%对 38.2%，P<0.0001）。与地理位置、年龄或种族分布无关。与自述皮肤“仅轻微敏感”或不敏感的受试者相比，有敏感皮肤的受试者主要为干性（34.5%）或混合性皮肤（35.7%），肤色较浅，对化妆品和各种环境因素的皮肤反应性更高，且更容易患皮肤病。皮肤科医生通过开具皮肤护理产品对“敏感”或“非常敏感”皮肤的患者有很大的影响。
本研究基于美国人群的代表性样本，揭示了美国敏感皮肤的高患病率。敏感皮肤主要与干性皮肤、浅色皮肤、对气候和环境因素的反应性以及化妆品有关。美国皮肤科医生似乎广泛参与了对这种疾病的护理。
