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.<br /><strong></strong></p><p><strong>Material and Methods:</strong> Application of a questionnaire and physical examination into a convenience sample, composed by adults from<br />20 - 60 years old that visited, in random days, five primary healthcare centers of the Greater Porto area.<br /><strong></strong></p><p><strong>Results:</strong> From the 1,055 evaluated adults, acne prevalence was estimated at 61.5%. Only 36.8% of acne suffering adults was aware<br />of 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.</p><p><br /><strong>Discussion:</strong> 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.</p><p><br /><strong>Conclusion:</strong> 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.</p>}, number={9}, journal={Acta Médica Portuguesa}, author={Semedo, Diogo and Ladeiro, Filipa and Ruivo, Mariana and d’Oliveira, Carlos and de Sousa, Filipa and Gayo, Mariana and Lima, Clara and Magalhães, Frederico and Brandão, Rui and Branco, Maria and da Silva, Isabel and Batista, Joana and Amado, João and Massa, António and Neves-Amado, João}, year={2016}, month={Sep.}, pages={507–513} }
