Aims: Sunbed use is common among adolescents, and may give an increment to UV exposure and an overall skin cancer risk comparable to that of the sun. Sunbed use was studied among 15- to 19-year-old adolescents in Stockholm County.
Methods: Data from two questionnaire surveys (1252 respondents in 1993, and 2950 respondents in 1999, survey tool partly revised) were analysed. By stepwise binary logistic regression the occurrence of sunbed use was assessed and analysed versus sunbed erythema, skin type, outdoor tanning, sunscreen use and smoking.
Results: Sunbed use declined between the surveys. In 1993, 70% of females, and 44% of males used sunbeds; in 1999, these were 45% and 19% respectively. Sunbeds were used against user recommendations. Of the sunbed users in 1993, 45% and 43% reported sunbed erythema; in 1999, 29% and 19% did so. Sunbed erythema, though related to sun sensitivity, occurred in all skin types. In both surveys, sunbed use was positively related to moderately sensitive skin type (females), outdoor tanning, and smoking (females). Smoking was a strong predictor for sunbed use among females in both surveys.
Conclusions: Even though different survey tools were used, and in spite of a decline in sunbed use, sunbed erythema was still common, and the relation to other health risk behaviour remained. Further research on sunbed use and its role in the aggregation of health risk behaviours in vulnerable ages is warranted, particularly its relation to outdoor tanning and smoking. A national and international harmonization of survey tools is also recommended for improved comparability.

Vitamin D is produced in the skin in response to UVB irradiation, from either sun exposure or UVB sunbeds. The objective of the current study was to characterize serum 25(OH)D response to regular sunbed use from several lamp outputs following their respective time exposure recommendations. There were three groups that tanned over 12 weeks during the winter months in dedicated sunbeds based on lamp outputs (100 W and 160 W low pressure fluorescent and 700 W high pressure filtered metal halide lamps) and a control group provided serum 25(OH)D samples at baseline and end-of-study.

In order to ground the credibility of the sunbeds' ultraviolet radiation compliance assessment with the 0.3W/m(2) erythema effective irradiance limit, it is highly important to use reliable measuring equipment and to justify reasonably the measurement's result. Recently, the first surveillance action of the artificial tanning sector in Greece has been finalised.

Ultraviolet radiation (UVR) is part of the electromagnetic spectrum emitted naturally from the sun or from artificial sources such as tanning devices. Acute skin reactions induced by UVR exposure are erythema (skin reddening), or sunburn, and the acquisition of a suntan triggered by UVR-induced DNA damage. UVR exposure is the main cause of skin cancer, including cutaneous malignant melanoma, basal-cell carcinoma, and squamous-cell carcinoma.

Increased use of indoor tanning for cosmetic purposes has led to concerns for its impact on the risk of cutaneous cancers. The effects on UVR on skin depend on radiant dose, i.e.

Even though UVA irradiance had not been considered detrimental to human skin for years, nowadays it is recognized for its role in photoaging and other biological responses. The ratio UVA/UVB is about 17 at a solar zenith angle (SZA) of 20° and it is almost constant up to 60° when it rapidly increases since the UVB wavelengths (280-320nm) are more attenuated than the UVA waveband (320-400nm). For a constant SZA, the ratio increases with the ozone content.
