Sun exposure habits and health risk-related behaviours among individuals with previous history of skin cancer.

AIM: The aim of the present study was to investigate possible associations between UV exposure and other health risk behaviours in different social environments and in regard to previous history of skin cancer.

PATIENTS AND

METHODS

In two closely-located, equally-sized cities in Sweden, representing different social environments (blue collar and white collar), patients aged 55-69 years, diagnosed with skin cancer (study group, n=489) or seborrhoeic keratosis (control group, n=664), were identified through a regional Health Care Register, and were given a questionnaire mapping for sun habits, tobacco smoking, alcohol use, and physical activity.

RESULTS

A previous history of skin cancer was associated with reduced UV exposure (p<0.01) and increased UV protection (p<0.001), higher alcohol consumption (p<0.05), and higher level of physical activity (p<0.05). Smoking was more common among subjects frequently sunbathing and rarely using sunscreen, but frequent sunbathing was positively associated with physical activity (p<0.05). Daily smoking and risky drinking habits were more common in the blue collar social environment, while no differences were seen for sun habits in this respect.

CONCLUSION

A previous history of skin cancer appears to promote increased UV protection. In contrast to alcohol/smoking habits, no association between social environment and sun habits was found.
