Summer weekend sun exposure and sunburn among a New Zealand urban population, 1994-2006.

AIM

To describe summer weekend sun exposure and sunburn experience, 1994-2006, among urban New Zealanders (15-69 years) by sex, age group, skin type and outdoor activity type.

METHOD

A series of five telephone surveys undertaken in the summers of 1994, 1997, 1999-2000, 2002-3 and 2005-6 provided a sample of 6,195 respondents with usable data from five major cities (Auckland, Hamilton, Wellington, Christchurch and Dunedin). Respondents were administered a Computer Assisted Telephone Interview (CATI) questionnaire which sought sociodemographic information, sun exposure, and sunburn experience during the most recent weekend.

RESULTS

Overall, 69% of the sample had spent at least 15 minutes outdoors between 11am and 4pm. Weekend sunburn was reported by 21%, and was more common among males, young adults and those with highly sun-sensitive skin than females, older adults and those with less sensitive skin. The head/face/neck was the body area most frequently and severely sunburned. Sunburn was associated with greater time spent outdoors and occurred most frequently during water-based (29%) and passive recreational activities (25%) and paid work (23%).

CONCLUSIONS

Sun protection strategies could usefully be targeted not only towards at-risk population groups, but also towards those activities and contexts most strongly associated with potentially harmful sun exposure.
