Doctors do not know why some people, particularly women, have persistent acne and others do not. New study Italian scientists concluded that the phenomenon may have many contributing factors.
Some of them are family history, poor consumption of fruits and vegetables and the intense stress.
In a study conducted with nearly 500 women found that these are some of the factors that significantly increase the chances to see the acne persists for many years after puberty.
Lead researcher Dr. Luigi Nalnti, director of the Research Dermatology Center GISED and Dermatology Clinic Papa Giovanni XXIII, Bergamo and colleagues interviewed 248 women with acne and 270 women in other skin problems, which were addressed in dermatological clinical 12 Italian cities.
As shown by their answers, the appearance of acne is associated with certain lifestyle factors, as well as family and personal medical history.
Thus, women who ate fresh fruits, less frequently than four times vegetables and fish a week had more than twice as likely adult acne compared with those eating daily fruit and vegetables and often fish.
Moreover, many reported severe or very severe stress, had three times the risk of persistent acne, and many were office workers were more than twice the risk than what housewives and unemployed women.
Other factors that increased the risk was the historical edge to parents or siblings (up 3 and 2.4 times, respectively), the personal history of acne in adolescence (5.4 times higher risk for adult acne) and increased facial hair and/or in the body (increases the risk 3.5 fold).
Although these findings do not mean that these factors are causes or that if women eat more fruits and vegetables will get rid of pimples, experts say it would be good to try to improve their diets and relax.
The findings were published in the December issue of the Journal of the American Academy of Dermatology.
