Defining "intermittent UVR exposure".

Background: Cutaneous malignant melanoma (CMM) has been associated with "intermittent UVR exposure", which in previous studies has mainly been assessed by retrospective questionnaire data. Further, there is no uniform definition of the term "intermittent UVR exposure".

Objectives: We aimed to define and quantify "intermittent UVR exposure" by an objective measure.

Personal UVR exposure of farming families in four European countries.

Background: The main risk factor for skin cancer is ultraviolet radiation (UVR). Farming families living in rural areas with easy outdoor access may experience excessive UVR exposure. Differences between countries in latitude, altitude and sun behaviour could result in different personal UVR exposures.

Sun exposure patterns of urban, suburban, and rural children: a dosimetry and diary study of 150 children.

Background: Sun exposure is the main etiology of skin cancer. Differences in skin cancer incidence have been observed between rural and urban populations.

Objectives: As sun exposure begins in childhood, we examined summer UVR exposure doses and sun behavior in children resident in urban, suburban, and rural areas.

UVR exposure and vitamin D in a rural population. A study of outdoor working farmers, their spouses and children.

Background: Living and working in the countryside may result in excessive UVR exposure, with increased risk of skin cancer. Some sun exposure is, however, recommended, since vitamin D production is UVB-dependent.

Objectives: To examine UVR exposure and vitamin D levels in a rural population of outdoor working male farmers, their indoor working spouses and their children, expected to receive high UVR exposure.

Good agreement between minimal erythema dose test reactions and objective measurements: an in vivo study of human skin.

Background/purpose: The erythema resulting from the minimal erythema dose (MED) test is subjectively assessed. The evaluator visually grades erythema on an ordinal scale. Both intra- and interobserver variation have been found for this erythema assessment.
