Assessing children's ultraviolet radiation exposure: The use of parental recall via telephone interviews
OBJECTIVES: This study evaluated the validity of a parental report measure of children's solar protection behaviors. METHODS: Fifty-eight children had skin color assessed twice with a colorimeter. Between measurement sessions, parents were interviewed by telephone to assess children's indoor-outdoor status and solar protection across 40 hourly intervals. RESULTS: Parental report of child's indoor-outdoor status was significantly correlated with t…
Assessing children's ultraviolet radiation exposure: The potential usefulness of a colorimeter
OBJECTIVES: This study evaluated the colorimeter as an objective measure of children's ultraviolet (UV) radiation exposure. METHODS: Fifty-eight children, ages 6 to 9 years, attended two summer measurement sessions, with 46 attending a subsequent winter session. RESULTS: Comparisons between summer sessions for the L* scale showed that only the upper arm significantly changed in the tanner direction, while b* scale values indicated significant tan…
