不良生活习惯让皮肤老化?

Don't blame genes for aging facial skin. A new study of twins suggests you can blame those coarse wrinkles, brown or pink spots, and dilated blood vessels on too much time in the sun, smoking, and being overweight.

　　皮肤老化？别怪基因。一项针对双胞胎开展的最新研究表明，皱纹、红褐斑以及血管瘤等皮肤问题和长时间日晒、吸烟以及体重超标有关。

　　Because twins share genes, but may have different exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues explain in the latest issue of Archives of Dermatology.

　　位于美国俄亥俄州克里夫兰的凯斯西储医学院的艾尔玛?D?巴伦博士及其同事在最新一期的《皮肤病学档案》中解释称，由于双胞胎拥有相同的基因，但可能受到的环境因素的影响不同，因此研究双胞胎可以“对基因易感性加以控制”。

Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.

　　研究人员对65对双胞胎的皮肤损伤环境影响因素进行分析后发现，环境和生活方式对皮肤老化的影响大于遗传因素。

　　But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.

　　但在皮肤癌的问题上，研究人员称他们的发现与之前的研究一样，认为环境和基因对患皮肤癌风险均有影响。
