引言回覆:

CHICAGO, Ilinois (Reuters) -- Smoking not only can wrinkle the face and turn it yellow -- it can do the same to the whole body, researchers reported Monday.

The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.

"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.

"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.

The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers

Independent judges decided how wrinkled each person's skin was.

When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.

這則新聞是摘自Archives of Dermatology(一本皮膚科雜誌)。

主要的發現是抽煙不只會使臉的皺紋增加,也使得全身其它沒有被日照的皮膚老化。

所以有時我看到那些模特兒在後台抽煙,都會想勸戒她們,畢竟模特兒是靠臉蛋和身材吃飯的,抽煙無疑是自毀前程。

文章中也有提到日曬對皮膚的傷害。不過,若為了怕皮膚受傷而不從事戶外活動,人生會減少很多樂趣,這就得自我斟酌了。

上篇新聞所引用的皮膚科雜誌(Arch Dermatol, Mar 2007; 143: 397 - 402)原文摘錄如下:

引言回覆:

Objectives To develop a reproducible photonumeric scale to assess photoprotected skin aging and to determine whether health and lifestyle factors, such as smoking, affect skin aging in photoprotected sites.

Design Using standard photographs of participants' upper inner arms, we created a 9-point photonumeric scale. Three blinded reviewers used the scale to grade the photographs. Participants answered multiple lifestyle questions.

Setting Academic outpatient dermatology clinic.

Participants Eighty-two healthy men and women aged 22 to 91 years.

Interventions A professional medical photographer took standardized photographs of each participant's upper inner arm. Participants answered standardized health and lifestyle questions.

Main Outcome Measures (1) Interobserver agreement and reproducibility using the photonumeric scale and (2) health and lifestyle factors most predictive of the degree of aging in photoprotected skin.

Results There was good blinded interobserver agreement as measured by the maximum range of disagreement scores for each participant (mean, 0.91; 95% confidence interval, 0.76-1.06). Results were reproducible. We developed a multiple regression model showing that the best model for predicting the degree of aging in photoprotected skin includes 2 variables: age and packs of cigarettes smoked per day.

Conclusions This photonumeric scale demonstrates good interobserver agreement and good reproducibility. Using this scale, the degree of aging in photoprotected skin was significantly correlated with patient age and a history of cigarette smoking. Additional studies are needed to continue garnering information regarding independent risk factors for aging of photoprotected skin.


本文附了一張皺紋評分表

0分表示光滑無暇;8分表示皺紋甚多。各位可以自行評分喔。
