摘要:
Background: Acne vulgaris is known as a commonly-seen skin disease with a
considerable impact on the quality of life. At present, there have been a growing
number of epidemiological, medical, demographic and sociological researches focusing
on various influencing factors in the occurrence of acne. Nevertheless, the correlation
between environmental factors and acne has yet to be fully investigated.
Objective: To assess the impacts of individual, natural and social environmental factors
on acne and to construct a framework for the potential impact of built environment
on acne.
Methods: A thorough review was conducted into the published social demographical,
epidemiological, and environmental studies on acne through PubMed, Google Scholar
and Web of Science, with reference made to the relevant literature.
Results: The influencing factors in acne are classed into four major categories. The first
one includes individual socio-economic and biological factors, for example, gender, age,
economic level, heredity, obesity, skin type, menstrual cycle (for females), diet, smoking,
cosmetics products, electronic products, sleep quality and psychological factors. The
second one includes such natural environmental factors as temperature, humidity, sun
exposure, air pollution and chloracne. The third one relates to social environment,
including social network and social media. The last one includes built environmental
factors, for example, population density, food stores, green spaces, as well as other
built environment characteristics for transport. Acne can be affected negatively by family
history, overweight, obesity, oily or mixed skin, irregular menstrual cycles, sugary food,
greasy food, dairy products, smoking, the improper use of cosmetics, the long-term
use of electronics, the poor quality of sleep, stress, high temperature, sun exposure,
air pollution, mineral oils and halogenated hydrocarbons. Apart from that, there are also
potential links between built environment and acne.Conclusions: It is necessary to determine the correlation between the built environment
and acne based on the understanding of the impact of traditional factors (sociology
of population and environment) on acne gained by multidisciplinary research teams.
Moreover, more empirical studies are required to reveal the specific relationship between
built environment and acne.
