Frequency of Sunburn in Queensland Adults

12% men and 8% women in Queensland sunburnt on

the previous weekend.

18-24 years 7x more likely and those 35-44 years 5x

more likely to report sunburn thank older people.

Sunburn remains a public health problem, especially in

young people.

9.3% squamous cell carcinomas

prevented fraction 14% of melanoma.

Typical levels of sunscreen use reduce skin cancer

incidence by 10-15%.

UV Skin Study Conclusions

The density of epidermal melanocytes 14 days after exposure

to 2 MED SSUVR was two-fold higher than baseline

(unirradiated) skin.

• The change in epidermal melanocyte counts among people

carrying the red hair gene (MC1R) was significantly lower than those

with wild-type MC1R.

• Sunscreen applied to the skin before exposure to 2 MED SSUVR

completely blocked the UV-induced skin damage measured

Text message interventions worldwide

Systematic review

8 studies fulfilled inclusion criteria (5 RCTS, 2 controlled

clinical trials, 1 cohort study).

5 used text messages, 2 mobile phone apps, 1 electronic

messages via email.

All studies resulted in at least one improved self-reported

behaviour.

Only one study used objective measure of electronically

monitored sunscreen.

Survey of Australian adults

People who worry about getting enough vitamin D

wear sunscreen less often (p=0.001);

wear shorts more often (p=0.04); and

tend to spend more time in the sun (p<0.001).

Research needed

Do risk calculators – indicators –apps assist

people making optimal decisions?

Do they improve sun protection or screening

behaviours?

Evidence so far is largely negative

Need better data on how they may impact

behaviours

Key Elements to Successful Skin Cancer Prevention Programs

R/ship between social, political, and economic environment

Established, effective, and well-resourced organisation

Access to resources

Congruency of aims among partners

Strategic planning

Strong research and evaluation base

Awareness of system change

Strategies across the whole system

Tailoring media message to environment

Potential negative effect of strategies

Motivating ‘hard-to-reach’ groups
