Acne really is a nightmare for some teens

Zits, pimples, bumps and blemishes are a young person's worst nightmare. Collectively they are known as acne, a very common skin condition that affects millions of adolescents. Now a Norwegian study published in the open access journal BMC Public Health has investigated the links between acne, diet and mental health issues in both males and females.

University of Oslo researcher Jon Anders Halvorsen together with co-authors from Lhasa (Tibet) and Boston (US) studied 3775 adolescents to explore the possible causes of acne. The 18- and 19-year olds were given questionnaires to monitor their diets, lifestyle variables, and mental conditions. Participants reported on their own acne. Lastly, researchers acquired the socio-demographic status of the young people from Statistics Norway.

The study identified crude associations between acne and high intake of chocolate and chips and low intake of vegetables. In girls, there was a significant link between acne and diet low in raw and fresh vegetables. This may indicate that a low-glycemic index could have a protective role in the development of acne.

Dr. Halvorsen said: "Our study shows a possible link between diet and acne. However, when we introduced symptoms of depression and anxiety in our statistical model, the role of diet became less clear. On the other hand the association between acne and mental health problems was still strong when diet was introduced. This underscores mental health problems as an important aspect of young people's acne".

He concluded, "It is too early to give evidence based diet advice to teenagers with acne. Further studies are needed. Luckily, acne is rarely associated with serious morbidity. However, it does cause problems for a high number of young people. I hope that this study will encourage doctors to help adolescents to treat their acne and researchers to find preventive factors. Young people deserve better!"

BMC Public Health (in press)

2. BMC Public Health is an open access journal publishing original peer-reviewed research articles in the epidemiology of disease and the understanding of all aspects of public health. The journal has a special focus on the social determinants of health, the environmental, behavioral, and occupational correlates of health and disease, and the impact of health policies, practices and interventions on the community. BMC Public Health (ISSN 1471-2458) is indexed/tracked/covered by PubMed, MEDLINE, CAS, Scopus, EMBASE, Current Contents, Thomson Reuters (ISI) and Google Scholar.

3. BioMed Central ( is an STM (Science, Technology and Medicine) publisher which has pioneered the open access publishing model. All peer-reviewed research articles published by BioMed Central are made immediately and freely accessible online, and are licensed to allow redistribution and reuse. BioMed Central is part of Springer Science+Business Media, a leading global publisher in the STM sector.

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
