Family sun-safety programme changed habits, not sunburn over time

Design

Randomised clinical trial, active education control

Population

364 melanoma survivors and their children aged 8 to 17 with a recent sunburn

Primary outcome

Change in child sunburn through two post-intervention assessments

Effect

No significant difference overall; sun-protective behaviour B = 0.26 (95% CI 0.14 to 0.38)

A randomised trial in JAMA Dermatology (7 October) enrolled 364 melanoma survivors with a child aged 8 to 17 who had been sunburnt in the past year. Families received four weeks of telehealth modules: either a programme teaching familial melanoma risk and sun-protection skills, or general education on finding reliable health information.

Over the whole follow-up there was no difference between groups in the change in child sunburn, the primary outcome. At the first assessment after the programme, children in the intervention group reported fewer sunburns, and sun-protective behaviour improved more in the intervention group through to the second assessment. Tanning did not differ.

Children of melanoma survivors carry about twice the lifetime risk of melanoma. Education alone shifted behaviour but not the outcome that matters. Clinicians seeing a melanoma survivor can still use the visit to raise their children's sun protection, but should not expect one round of teaching to be enough.

• Ask melanoma survivors whether their children have been sunburnt in the past year.
• Explain that children of melanoma survivors carry about twice the lifetime melanoma risk.
• Give specific sun-protection advice for children: shade at midday, clothing and hats, and broad-spectrum sunscreen reapplied.
• Revisit sun protection at later visits rather than relying on a single conversation.

Why it matters

It shows that teaching high-risk families improves what they say they do faster than it changes how often children burn.

Don't overread it

The early fall in sunburn was a secondary time point, not the primary outcome, which was negative.

The statistics, in plain English

The primary analysis looked at the change in sunburn across all follow-up and found no difference. The positive result at the first assessment is one of several time points and is weaker evidence. Both groups received some education, which makes a difference harder to show.
