Predictors of sunburn in North Queensland recreational boat users.

ISSUE ADDRESSED: Identify personal and situationalfactors predicting sunburn in north Queensland recreational boat users over summer.

METHODS

Cross-sectional survey with prospective 24-hour follow-up for sunburn, conducted in Townsville, north Queensland, during the summer of 2003. Ninety-three out of 100 boat users returning after a day trip agreed to participate. All were followed up, with three later excluded from analysis due to prior sunburn (n=90, response rate 93%).

RESULTS

Overall, 48% of participants experienced sunburn as a result of their boat trip; 57% of these developed sunburn on the face and 43% on both the V of the neck and the legs. Factors found to increase the occurrence of sunburn were longer time on the water between 10 am-2 pm, not wearing a wide-brimmed hat, not working outdoors, and going boating less than once per month.

CONCLUSIONS

The survey shows unacceptably high levels of sunburn in north Queensland boat users. Sunburn appears related to not using optimal sun protection between 10 am and 2 pm. Boat users in the tropics need to wear a brimmed hat to better protect the face, a collared long-sleeved shirt buttoned up at the throat to protect the V of the neck and arms, long pants, and rely less on sunscreen and on darker skin types that are perceived to sunburn less readily.
