title: Adult Acne: Prevalence and Portrayal in Primary Healthcare Patients, in the Greater Porto Area, Portugal.
abstract: BACKGROUND
  Though typically found in adolescents, acne frequently affects the adult population. In Portugal, no representative studies about acne prevalence in greater populational areas are known. This study had the following objectives: calculate acne prevalence in primary healthcare patients; its characteristics, including risk factors for onset and worsening; collect information concerning selfmedication and/or prescribed treatment.
  
  
  METHODS
  Application of a questionnaire and physical examination into a convenience sample, composed by adults from20 - 60 years old that visited, in random days, five primary healthcare centers of the Greater Porto area.
  
  
  RESULTS
  From the 1,055 evaluated adults, acne prevalence was estimated at 61.5%. Only 36.8% of acne suffering adults was awareof their condition. More than half of tobacco users (62.3%) had acne. Just 25% of acne sufferers sought treatment. The most affected areas were the malars, differing from the younger disease form.
  
  
  CONCLUSIONS
  Acne prevalence was relatively higher than other studies. The results of this study have confirmed that acne seems to be related with increased calorie intake, tobacco smoking, whole milk and fat-reduced milk consumption, hirsutism, alopecia and seborrhea.
  
  
  CONCLUSIONS
  In the primary healthcare set, more than half of adults were acne sufferers. These numbers show how important primary healthcare services can be in preventing and intervening when managing acne-related risk factors and psychosocial consequences.
